The Media How realistic is the media’s presentation of women? Women and men come in all shapes and size, yet constantly the media presents us with only one ‘image’ – a very slender and unrealistic one. Only a small percentage of women actually look that way naturally. We forget when looking at these pictures that the best lighting and photographic equipment, hours with make-up artists and wardrobe assistants have been necessary to make these women look so ‘natural’. What is the media trying to do by constantly presenting us with unrealistic images? Deliberately convince us that we are not good enough as we are. To make us believe that in order to be happy, successful and popular we must change – we must try and mirror the media image.

Factors Affecting the Success of Mega

Factors Affecting the Success of Mega Introduction In the recent past, the popularity of events management and related projects has increased. According to Bladen (2010), the phenomenon involves the application of project management concepts to the administration of events and occasions. In this paper, the author will analyse a number of contemporary issues affecting the management of these undertakings.Advertising We will write a custom critical writing sample on Factors Affecting the Success of Mega-Events specifically for you for only $16.05 $11/page Learn More To this end, the author will review 6 articles reporting on various issues in this field. A key theme affecting the operations of a manager operating in this field in each of the articles will be identified and critically reviewed. Contemporary Issues in Events Management Media Representation of Volunteers at the Beijing Olympic Games (Charles Richard Bladen) Volunteers play a major role in the management of activities related to many events. Bladen (2010) explores how the media represents volunteers in sports. Bladen analyses this issue from the perspective of the 2008 Beijing Olympics. The major theme in this article is the portrayal of volunteers in mainstream media. According to Bladen (2010), the Chinese and foreign media houses varied in their coverage of assistants involved in the Olympics. The local media portrayed these individuals as the force behind the success of the mega-event. The foreign media, on the other hand, treated volunteers as a ‘front’ for the Chinese government. According to Bladen (2010), Chinese media tended to glorify the parties, while foreign media focused on their shortcomings. The media is a very influential force, especially in gauging the success of managing an event like the Olympics. In some cases, media outlets can distort the outcomes of an event. Such distortions can occur in situations where there are conflicting representations, like in the Olympics Games. Bla den (2010) feels that the reporting of volunteering in sporting events lacks sufficient research. The media pays more attention on the individuals engaged in the sports and the actual games, ignoring the parties that provide their services for free. In future, the media can be harnessed to manage mega-events, such as the Olympics. The success can be achieved by acknowledging the individuals behind the preparation and execution of such activities. Beijing Olympics Games would have been depicted as a success if the conflicting representation of the volunteers did not give rise to extraneous issues, such as politics. Bladen (2010) addresses the problem of differing representation of volunteers in the games by analysing the major issues revolving around their roles. The motives behind the activities of these individuals are established by focusing on their duties and how they are treated by the media.Advertising Looking for critical writing on business economics? Let's see if w e can help you! Get your first paper with 15% OFF Learn More The misrepresentation of volunteers in the Olympics Games had negative impacts on Chinese legacy. The misinformation raised questions about China’s sincerity and competencies in managing such events. The Chinese were depicted by the media as friendly and accommodating hosts. However, their government was regarded as ‘Big, Bad China’ (Bladen 2010). The biased reporting in the media cannot be ignored. Such skewed representation extends to the treatment of volunteers by local and international news agencies. As an events manager, the author of this paper feels that the media plays a significant role in the success of events. In addition, the invaluable contribution of volunteers cannot be ignored, irrespective of their skills. However, the coverage of events by the media should be independent from popular themes and attitudes surrounding the culture or politics of the people. The Conceptual isation and Measurement of the Legacy of Mega Sporting Events (Holger Preuss) The legacy of any event significantly influences the management of similar occasions in the future. In their article, Preuss (2007) reviews the nature of the legacies left behind by large scale sporting affairs. The impact of such events is the major theme in this article. Definition of the term legacy, especially in relation to events, is not clear cut. As a result of this, the International Olympic Committee has made efforts to clarify sporting activities and their impacts. The value derived by communities or sports organisations from games, as well as the value of the sporting facilities, constitutes the legacy of sports events. According to Preuss (2007), the effects of any sports undertaking on the community and on other stakeholders can either be positive or negative. They can also be planned or unplanned. The impacts of the event on sporting structures may persist for a long time. As an events manag er, it is important to note that the intended and unintended legacies of a mega sporting undertaking determine the management of the entire undertaking. In addition, the benefits that members of the community derive from the occasion determine its success or failure. Considering the massive investments made in large scale sporting events, the manager should take the lasting legacy very seriously. The impacts are part of the occasion’s return on investment.Advertising We will write a custom critical writing sample on Factors Affecting the Success of Mega-Events specifically for you for only $16.05 $11/page Learn More Gauging the lasting impression of sports is very important in the management of these undertakings in the future. For instance, the manager should determine the extent to which the event benefits members of the society. To this end, those undertakings that have positive impacts on the community should be prioritised. There are several met hods used in measuring the legacy of large scale sporting affairs. They include the benchmark, the top-down, and the bottom-up approaches (Preuss 2007). As an event manager, the author of this paper agrees with Preuss that the bottom-up approach is more comprehensive, effective, and adequate compared to the rest. It is important to determine the structural changes brought about by ‘super-events’ (Preuss 2007). In addition, the manager should gauge the emotional impacts of the occasions, as well as their impacts on the image of the country. For instance, the enhancement of the country’s image as a result of hosting the Olympics is a major aspect of the event’s legacy. In the opinion of this author, the future of such large scale sporting organisations as the FIFA World Cup depends on their legacies in relation to the hosting nation. With regards to the current global economic turmoil, countries are taking the issue of the impacts of events very seriously. A s a manager, this author will strive to enhance the effects of large occasions using the pre-event, event, and post-event legacy framework. Hosting Business Meetings and Special Events in Virtual Worlds: A Fad or the Future? (David M. Pearlman Nicholas A. Gates) The contemporary world is characterised by significant developments in relation to information and technology. Today, technology is emerging as an essential aspect of almost all human undertakings. Events management is one of the areas in the modern world where technology is utilised. The application of technology in managing events is the major theme in this article. Pearlman and Gates (2010) carried out a study to determine virtual reality and its significance to contemporary organisations. The two sought to examine the adoption of this technology in businesses, special parties, and meetings. The viability of virtual reality applications in today’s business world was also analysed. According to Pearlman and Gates ( 2010), the term ‘virtual reality’ is used in reference to computer-simulated environments. The technology is used to ‘imaginarily’ replicate the real world. A number of computer applications are used to generate 3D visual environments that constitute the virtual world.Advertising Looking for critical writing on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Most professionals lack information on virtual reality applications. However, in spite of these inadequacies, the use of this technology in the business world is on the rise. Some of the applications available in the market include WebEx, 3D SL, and ON24 (Pearlman Gates 2010). The most significant contribution of virtual reality to the profession is the development of virtual events. They are gaining popularity because of several factors. Users are becoming used to online platforms. Maturation of virtual technologies and the availability of high bandwidth are some of the other factors enhancing virtual events. Holding virtual conferences and such other undertakings reduces operational costs in the organisation. Such reduced expenditures have increased the popularity of these kinds of meetings and conferences. In spite of the economic benefits associated with this technology, Pearlman and Gates (2010) note that some organisations are reluctant to adopt virtual reality. The study ill ustrates uncertainties about the future of this technology as one of the reasons behind the reluctance. However, considering the advantages associated with virtual events, these doubts are unjustified. Reports of similar undertakings hosted virtually by such organisations as IBM and American Cancer Society highlight the reliability and usefulness of these applications (Pearlman Gates 2010). Global pandemics, such as Influenza, and an increase in travel costs, have led to reduced physical participation in conventions and such other business gatherings. Virtual events have little or no carbon footprint. Such an attribute is important in the contemporary world where people are concerned with global warming. It is important to note that holding large scale events on the virtual platform is a difficult undertaking. In spite of these difficulties, it appears that the growth of these undertakings will increase in the future. Furthermore, simulating mega-events enhances the success of actu al ground occasions. The Effects of Facebook Users’ Arousal and Valence on Intention to go to the Festival: Applying an Extension of the Technology Acceptance Model (Woojin Lee, Lina Xiong, and Clark Hu) The influence of social media platforms on marketing is a force to reckon with in events management. Large groups of people and corporations come together on social media sites. The link between Facebook as a social medium and management of activities is the main theme in the report cited above. Lee, Xiong, and Hu (2012) acknowledge the influence of social media on events marketing in the contemporary world. The sites make it possible to communicate directly with potential event attendees or the target audience. In addition, the gathering of first hand reactions and suggestions regarding events is made easy. Lee et al. (2012) sought to determine whether Facebook users actually respond to events communicated through the social media site or not. Lee et al. (2012) used the tech nology acceptance model (TAM) to assess how arousal and valence influenced the response of Facebook users in relation to events marketed via the site. The theory of reasoned action (TRA) forms the basis of TAM. It explains the construction of behaviours by individuals (Lee et al. 2012). According to Lee et al. (2012), individuals’ reaction to technology is informed by its perceived ease of use and applicability. Using TAM, Lee et al. determined that emotions are a major factor as far as responding to a Facebook marketing event is concerned. The importance of Facebook as a marketing tool is undeniable. For instance, every month, approximately 3.5 million events are advertised on the site (Lee et al. 2012). The sheer volume of users makes the site a prime tool for managers keen on wooing attendees, especially in relation to mega-events. However, ensuring that the users respond to the advertisements is a different matter altogether. Lee et al. (2012) found that users who experie nce high levels of arousal and valence from the advertisement are more likely to access Facebook pages than their counterparts. Such users are also more likely to respond to the events marketed there compared to other individuals. Technology advancements give rise to new marketing options. Organisers adopt the most effective of these alternatives. Understanding the factors influencing these options will ultimately determine the success of marketing. Social media marketing is important in reaching out to those users that are technologically savvy. Facebook is one of the most popular platforms used in relation to this form of marketing. To determine the future responsiveness of these users, managers should focus on the perceived value of this social site. The event page should be easy to navigate. Updating the content on such pages will also enhance the success of future events. The Development of Competitive Advantage through Sustainable Event Management (Stephen Henderson) The artic le by Henderson (2011) revolves around the theme of sustainable event management. Henderson (2011) emphasises the need for organisations and event organisers to meet their projected desires. The managers can achieve this through sustainable application of both human and physical resources. Sustainability implies a form of development that meets the present human needs. The development also makes some compromises to help future generations meet their own needs. The definition of sustainable events encompasses several issues. In a broad sense, the definition brings together both the process and the outcome or product of the event. The two aspects imply undertakings organised to meet sustainable standards to enhance the benefits accrued to the audience (Henderson 2011). To this end, a sustainable event should be beneficial to the people and the planet as a whole. In addition, it should meet the interests of the investors. Public and private sector occasions differ in relation to sustai nable management. The former are more concerned with the public welfare. Organisers of such undertakings strive to help the people and to safeguard the environment. On the other hand, management of private sector events mainly focuses on profit generation at the expense of the people and the planet (Henderson 2011). Sustainable coordination of activities may be compromised when competitive advantage is sought. However, cost leadership and focus and differentiation strategies can be used to enhance sustainability without negatively affecting the profitability aspect of these investments. Differentiation and focus approach is people oriented. The event organiser focuses on the delivery of unique utility to the audience. Both approaches enhance profits since the consumers are drawn to the event by the qualities they desire. As such, they are likely to contribute generously to support the process. Conflicts are likely to occur between sustainable management and cost leadership, especial ly with regards to the creation of competitive advantage. It is noted that most of the strategies used in lowering costs disregard the sustainability aspect of the event. For instance, generation of green energy to support the activities associated with Olympics may be costly compared to the use of fossil energy. Such an event addresses the issue of sustainability, but negatively impacts on profitability. To realise sustainability, future event organisers should try to combine the various competitive elements of management. An event geared towards differentiation and focus is more likely to achieve the sustainability target. The same is not guaranteed when a competitiveness strategy is adopted. Sustainability is an important element in contemporary business management. Managers should realise the importance of upholding sustainability in their undertakings. Sustainability-oriented societies will most likely respond to sustainable events, irrespective of the price they are required t o pay to enjoy such undertakings. Relationship Marketing of Services: Growing Interest, Emerging Perspectives (Berry 1995) Berry (1995) addresses the theme of relationship marketing of services in the context of events management. The author views the concept as a collection of activities involved in the attraction, maintenance, and enhancement of client relationships. It is noted that most mega-events are products of multiple services organisations. As such, the importance of relationship marketing in this field is irrefutable. The analysis of Contact Theatre relationships and marketing of services by Berry (1995) brings to light some essential aspects of relationship marketing. The interaction between the theatre and the various stakeholders reveals the framework adopted by this organisation in promoting its services. Berry (1995) regards the nature of interactions as a vital element in the success of the theatre. The success is especially determined by the response to the convent ions and other gatherings held. Contact Theatre nurtures relationships with various individuals involved in the running of the business. They include, among others, teachers and youthful workers. The interactions with local, national, and international arts organisations highlight this connection. The link between arts directors and members of staff, for example, indicates internal relationships. According to Berry (1995), marketing differs depending on the nature of relationships exhibited in an organisation. The differences are inevitable since the roles of the individuals or groups in the interaction also differ. For instance, the marketing of internal engagements should focus on attracting and developing qualified employees (Berry 1995). Internal employees and the audience are the most important stakeholders with regards to the activities carried out at Contact Theatre. As such, internal marketing is essential since the services produced involve performance. To this end, the emp loyees are the performers (Berry 1995). Collaboration with the audience is the only means through which the theatre can achieve its objectives. The success of Contact Theatre is measured using the status of the relationships it has with stakeholders and the response of the audience. The more people respond to artistic events, the more the success of the managers. Contact Theatre is a non-profit organisation. In the opinion of this author, management in this entity differs significantly with the coordination of activities in private commercial organisations. The objectives of the latter involve the establishment of relationships geared towards the generation of revenue. On the contrary, Contact Theatre focuses on sustainable relationships with the society and other stakeholders. The internal and external stakeholders regard their relationship with Contact Theatre positively. The former regard this engagement as an open undertaking, leading to high levels of satisfaction and mutual in terest. The external stakeholders view their interaction with the theatre as representative of all groups.

Business Plan - Essay Example Stern measures have to be taken by the tour operators as far as safety and health assessments are concerned as Controls are not rigorous. This would help to safeguard the agency also against any litigation. Assessments of health and safety should be carried out throughout the tour (Daily Mail, 2006). While tour operators have to rely on the guarantees provided by the hotel authorities, BE should ensure that its terms and conditions of joining the tour are well laid out while setting up the business as tour operators could be subject to civil liability (AHS, 2007). While WTO predicts international travel will grow annually at the rate of 4.1% up to 2020 but various factors pose a risk to tourism. These include economic stability, world terrorism, and global climate changes. The UK travel sector is just recovering from the recent airport chaos and the threat of terrorist attack. Fear of terrorism affects global travel demand and the targets set by BE is a very optimistic figure. Tourism is a very sensitive sector and destination factor is very important. BE intends to focus on the affluent class and predominantly on adventure tourism. The company has not attained any experience in this segment and it would be advisable to have another sector and segment to fall back upon initially till it gets established. The number of holidays on offer should be limited to start with. Security situation puts holiday firms in a difficult situation (Reuters, 2007). Lessons can be learnt from the giants in the industry who have been able bring a turnaround despite the effects of football World Cup, avian flu, terror threats and the hot summer in UK (Mall, 2007). This has required a dual measure of huge investments and cost-cutting in various areas. BE plans to build brand awareness in the first year but would have to consider the consolidation taking place in the UK travel market as big firms are merging. This definitely means less competition but there is an oversupply of

The Smartphone Security Awareness Information Technology Essay

The Smartphone Security Awareness Information Technology Essay Over the past decade mobile phones have become pervasive and have evolved significantly from feature phones to smartphones to fit the increasing needs of the competitive market and to meet consumers wants and needs. The purpose of this research paper is to provide insight and raise security awareness into the risks posed by unsecured smart mobile devices. Smartphones are ubiquitous devices and are comparative to the personal computer in terms of computational power, choice of operating systems, software with the same extended features and the ability to support 3rd party software. Smartphones have enabled businesses and their workforce the freedom to collaborate and access organizational data 24 hours a day, 365 days a year. What has been done to protect individuals and businesses from the ever increasing threat of mobile orientated attacks? Pervasive computing (also called ubiquitous computing) Endpoint security antivirus/malware enterprise information infrastructure mobile information security perspective security awareness training technical topics are outside the scope of this research Introduction The purpose of this document is to expose a business problem from a technological viewpoint. The subject of the business problem I have selected is on smartphone security awareness. This subject will be analysed and critically evaluated, then expanded upon further to reflect the range of possible solutions and create a comprehensive guide for the benefit of the reader. 1.1 Motivation The motivation for this project was mostly due to my vocational role as an IT consultant. During the course of my employment over the past decade within the IT industry, I have noticed a substantial gap within businesses for the need of greater smartphone security and awareness. It was obvious to me that along with the evolution and improved capabilities of cellular devices, established a greater risk for organisations. This thesis is the result of work I have personally carried out in various roles throughout my technological career between October 2004 and December 2010. 1.2 Aims and objectives The following are my aims and objectives for this project Aims Create an authoritative document with recommendations to raise awareness and inform businesses for the need of greater mobile security within the business environment. Use insight to establish a research gap. Main objectives Assess smart mobile devices currently used. Analyse security advantages and disadvantages of smart mobile devices. Establish what risks smart mobile devices are exposed to. Evaluate impact of risk exposed by unsecure mobile devices to businesses. Examine mobile security currently available. Investigate responsibility Evaluate current business policies and procedures for mobile devices and how these are enforced. Construct smartphone security guide with recommendations for businesses. 1.3 Problem Statement The problem is information and financial loss due to information theft or inaccessibility from malicious software (malware), and the detrimental impact this has upon the business. There are many types of information that can be stored on smartphones for example, personally identifiable information in the form of contact details (phone, address), email, GPS coordinatesà ¢Ã¢â€š ¬Ã‚ ¦ Information security has gained significant value within the business domain over the past decade however this value remains subjective. Users have been made aware of the risks posed by malicious software whilst using their personal computer on the internet, now assistive technology like smart mobile devices are becoming increasingly more powerful, functional and ubiquitous. Where personal computers have at least some security software in place as standard, smartphones commonly have no security software installed and are susceptible to the same threats as personal computers. Businesses, professionals and personal users now have a greater awareness for the need of personal computer security. This has been provided by media coverage, enterprise training or through personal experience. When using a personal computer or laptop for example, it is common to find a firewall and antivirus software installed showing that internet safety has now become a social normalcy. Example http://www.bloobble.com/broadband-presentations/presentations?itemid=3397 Data loss or inaccessibility due to a virus, data theft due to Smartphones are high specification mobile personal computers, and are subject to the same risks personal computers are open to. There are four to five billion mobile phones and we are approaching a billion smart phones. But remember that these devices are more powerful than supercomputers were a few years ago, and we are putting them in the hands of people whove never had anything like it before. Google CEO Eric Schmidt Businesses need IT to function, IT adds value and to compete in todays economic climate. ITs purpose is to save time, time is money. Todays organisations rely heavily upon information technology in order to allow their business to function (Khosrowpour, 2001). This is fundamentally due to how intricate information technology systems are embedded into organisations. Enterprise architecture (EA) is a communication tool between IT and business (Zachman, 2004). EA is multifaceted (Wagter et al, 2005) and for the scope of the project I will be examining how the Security Architecture (SA) facet can benefit organisations to secure the Information Technology within the business against the increasing threat that unsecured mobile devices pose. There are many different mobile operating systems for smart mobile devices requiring different security applications. I will analyse these systems and the risks associated. My intentions are to investigate what impacts smart mobile devices can have on businesses, why these problems affect the organisation, and how they are overcome. Finally I will gather insight and make recommendations that businesses can use to foresee and prevent future unnecessary costs and risk. 2 Literature review 2.1 Background The subject I have proposed to use for this project is a very real-world business and information technology problem. Because smartphone security is still in its infancy, it is currently quite a challenge to source accurate and relevant information from authoritative sources such as Emerald without resorting to web based research. However, the more this project advances smartphone security in the media is becoming omnipresent. The first documented computer virus was designed over 25years ago by two brothers named name 1 and name 2 in Pakistan, the virus was called the brain virusà ¢Ã¢â€š ¬Ã‚ ¦ Timeline evolution of the mobile telephone (Malware) Analogue Cellular Mobile History / Uses 2.2 Current status/Development of theories Information is all that needs to be secured. Malware is changing, smartphones are changing and businesses are changing. How far up the technological ladder are mobiles/feature phones/smartphones 2.3 How this project fits in with the literature review I had chosen the subject then chosen the literature review method, thus tailoring the literature review to fit the requirements of the project. 3 Research methods 3.1 Introduction: hypothesis Throughout my employment, I recognised a gap and need for smartphone security within 3.2 Epistemology http://www.learnhigher.ac.uk/analysethis/main/quantitative1.html One of the methods of analysis I will to use is the conceptual method, this has been described by Beaney as a way of breaking down or analysing concepts into their constituent parts in order to gain knowledge. Conceptual analysis consists primarily in breaking down or analysing concepts into their constituent parts in order to gain knowledge or a better understanding of a particular philosophical issue in which the concept is involved (Beaney 2003). I have interpreted this to mean the compartmentalisation and analysis of data. The proposed project will be delivered using an analytical in-depth research structure. I have chosen this project structure as it will primarily be research based on the current business problem as previously stated. I intend to analyse this problem, propose possible solutions, test and implement a well-documented solution with recommendations. Critical and creative thinking skills such as Edward.De Bono six thinking hats will be used to examine the problem domain. A review will be given on how the systems work and compare them to how they should work. I will then analyse the solution domain by examining which options are available to improve the system security along with an optimal recommendation and the benefits it would provide. 3.3 Methodology Figure research methodFor my project I will implement a triangulated, positivistic methodological approach, I have chosen this particular technique as it will provide me a balanced view of the subject area. I will incorporate both quantitative and qualitative primary research methods as recommended by Bryman (BRYMAN, 2006). However for the scope of this project I will be mostly using Quantitative based research as indicted in Fig 1 below. . Bryman advises that quantitative data can be gathered by way of a survey and qualitative research collected from journals and interviews. Initially I will undertake primary research in the form of a survey questionnaire, and furthermore I will interview professionals in the field of smartphones and security such as police personnel, security advisors and mobile phone shop staff. The survey will be available to respondents in paper form and electronically hosted so any user with internet access may access it. I will design the survey to be concise and simple to maximise the amount of respondents and gain quality information. My target survey participants are business managers, IT professionals and general smartphone users. I have chosen to target these particular users as I am trying to ascertain not only the perception of smartphone security but also what policies and procedures are put in place and how aware users are of these. I have proposed to target these users by using a popular internet based technological social news website named Reddit. Reddit has a daily turnover of over 850.000 unique users (Alexa, 2010). According to Alexa the average Redditor is male, between the age of 18 to 44, does not have children, is well educated and browses Reddit either from work or home, suggesting that the majority of Redditors are working professionals and due to being a technological social news website the average user is technologically aware (Alexa, 2010). This confirms my premise and establishes that Reddit would suit my proposed target survey participant. There are many options available for online survey software, each option has its benefits and weaknesses, I have carefully analysed these options personally and have chosen to utilise the cloud based option Survey Monkey to host my survey. The default limitations of Survey Monkey are the survey itself has been designed to be logical with closed questioning and Qualitative data has been sourced from reliable and authoritative resources. I have chosen journals from Emerald Primary research methods used Interviewing mobile phone shop staff, police, business owners I will critically analyse the results of my survey by comparing the answers given to a risk register. 4 Results 4.1 Presentation and description of results Who took part? A survey was conducted to establish the awareness for the need of smartphone security. Users were openly invited from technological backgrounds to partake in the survey and assured of anonymity. A total of 758 people responded to the online survey from a possible 854,998 potential participants. The survey itself was open for one month during February and March 2011. The results indicated that majority share with 82% of survey responders being male as opposed to the 18% that were female both averaging at 26 years of age, this confirms part of my original hypothesis as an average smartphone user. When asked, 53% of respondents reported that they had used their smartphone solely for personal use as opposed to the 45% of partakers that reported they used their smartphone for both business and personal use, with just 2% reporting to use a smartphone solely for business use only as shown in Fig 2 combining a total of 47%.C:UsersLeeDesktopUniUniversity 2010_11MikeDissertationDocumentsDissertationSurveySurvey monkey charts8 FeaturesSM_Features_Line.png Figure Smartphone use 25% of respondents had only been using smartphones for the past six months, 17% were aware they had been using them for at least a year and a majority percentage of 59% had been using smartphones for more than one year.

Harris Interactive: Tablet users more likely to transfer sensitive data than smartphone users Serendipity, sagacity 5 Smartphones A mobile phone is a portable electronic device used to make and receive telephone calls. The mobile phone was first revealed by Dr Martin Cooper from the company Motorola in 1973, it was not until ten years after Dr Coopers demonstration that Motorola released its flagship mobile phone the DynaTAC, this was the worlds first commercially viable mobile phone (Motorola, 2009). Originally these devices were commercially targeted at businesses and upper class individuals as the cost of the device was very high and the actual usage was severely restricted, due to the technology limitations at this time battery weight was 2kg (Motorola, 2009) and the battery duration would last a maximum of 30 minutes thus making the device impractical and available only to businesses and professional consumers. According to Moores Law, the number of transistors on a chip roughly doubles every two years. (Intel, 2005) As Moore stated over thirty five years ago, due to the advancement of processors, battery technologies and overall reduced power consumption, mobile phones have become lighter, smaller, more powerful and longer lasting. Due to these fundamental technological advancements mobile phones have been able to incorporate additional existing technologies such as camera units, sensors, speakers and often take advantage of JAVA based applications and features, thus coining the term Feature phone. Feature phones are more advanced technologically than mobile phones. Smartphone The term smartphone is ambiguous and many experts fail to agree on a suitable definition. Most smartphone features are not exclusive to a particular category, this project does not intend to make that definition, however for the scope of this project I have listed combined definitions and compared current smartphone features as listed in Figure 3 below. Most vendorsà ¢Ã¢â€š ¬Ã‚ ¦ type more Gartner, a world leading authority in information technology research define smartphones as A large-screen, voice-centric handheld device designed to offer complete phone functions while simultaneously functioning as a personal digital assistant.'(Gartner, 2010) Feature phones can have several of the characteristics as listed below in figure 3, however smartphones have the capability of providing all the capabilities. As a result, any mobile device meeting all conditions of each function in figure 3 can be considered a smartphone under this definition. Figure Smartphone characteristics Function Characteristic Phone size Device is compact and easily transported. Operating System Operating system that allows third party applications. Connectivity Device provides multiple methods (wired and wireless) of connecting to both the internet and other devices and networks. Input The device contains keyboard, or touchscreen keyboard. Storage capacity The device has a large and expandable storage facility. Office functionality The device provides the ability to perform basic office tasks such as email, take notes and word processing. Calendar The device includes a digital organiser and calendar. Synchronisation The device supports synchronisation of information with fixed desktop or laptop devices, or online web services. Phone Features The mobile device executes voice, text and multimedia message functions. Sensors Acceloratormeter, light, sound and movement sensors. A model to measure the maturity of smartphone security at softwareà ¢Ã¢â€š ¬Ã‚ ¦ Under this definition of smartphones or Smart Mobile Device (SMD) the following mobile platforms were included: Apple iOS Blackberry Google Android Symbian Windows Mobile These mobile platforms were reported to be the top 5 mobile platforms used in 2010 Figure (?) Storage expansion cards Smartphones currently reside in the top tier of mobile communication technology. Third party operating system As previously stated there are many smartphone platforms available, each platform and brand bringing different benefits and functionality. These platforms or operating systems create opportunities for both businesses and personal users. For businesses this increased functionality provides the facility for added employee productivity. These opportunities exist not just for business and personal users as the opportunity extends to the bad guys too, I will continue to explain further in the document. Smartphone Definition A smartphone is defined as A cellular telephone with built-in applications and Internet access (PCMAG, 2010) describes a smartphone as a à ¢Ã¢â€š ¬Ã‚ ¦ andà ¢Ã¢â€š ¬Ã‚ ¦ describes it asà ¢Ã¢â€š ¬Ã‚ ¦I have interpreted these descriptions and define smartphones as not feature phones basically. All smartphones have generalised functionality, such as input devices (keys, touchscreen) I will go into greater detail regarding the operating features Botha, et al (2009) point out that early generations of cell phones and PDAs had relatively little storage capability. Johnson (2009) indicates that todays generation of devices can be quickly and easily upgraded by adding additional storage cards. http://mobileopportunity.blogspot.com/2007/01/shape-of-smartphone-and-mobile-data.html 5.1 Apple The Apple Iphone was the original smartphone (), first released in June 2007.

Contrasting Fortinbras and Laertes with Hamlet Essay -- comparison com

     Ã‚   In William Shakespeare's tragedy Hamlet, Laertes, Fortinbras and Hamlet find themselves in similar situations.   While Hamlet waits for the right time to avenge his father's death, Laertes learns of his father's death and immediately wants vengeance, and Fortinbras awaits his chance to recapture land that used to belong to his father.   Laertes and Fortinbras go about accomplishing their desires quite differently than Hamlet.   While Hamlet acts slowly and carefully, Laertes and Fortinbras seek their revenge with haste. Although Laertes and Fortinbras are minor characters, Shakespeare molds them in order to contrast with Hamlet.   Fortinbras and, to a greater extent, Laertes act as foils to Hamlet with respect to their motives for revenge, execution of their plans and behavior while carrying out their plans.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Although each character plots to avenge his father in the play, the motives of Laertes and Fortinbras differ greatly than that of Hamlet.   Fortinbras, who schemes to rebuild his father's kingdom, leads thousands of men into battle, attempting to capture a small and worthless piece of Poland. After his uncle warned him against attacking Denmark.   The added land will do little to benefit Norway's prosperity, but this campaign may cost "two thousand souls and twenty thousand ducats" (4.4.26) .   This shows that pride is a driving factor behind Fortinbras' plan because he is willing to put the lives of his countrymen at risk for a minimal gain.   Laertes, on the other hand, is compelled to seek revenge because he loses his father and eventually his sister.   The root of Laertes' revenge appears to be the love for his family because he proclaims that he will "be revenged / most throughly for [his] father" (4.5... ...side Shakespeare.

Industrial Instrumentation On Load Cells Engineering Essay

Load cells are detectors which are used to mensurate the degree or force per unit area by change overing the force ( torsion or mass ) into electrical signals and so these signals are displayed by the show unit to demo the degree or force per unit area. Load cells are besides known as burden transducers. In dictionary, a burden cell is known as â€Å" weight mensurating device necessary for electronic signal that displays weight in the signifier of figures. † Load cells can be classified harmonizing to their operations: Load cells that utilize liquid force per unit area or air force per unit area. Load cells that utilize snap. Load cells that utilize a magnetostriction or piezoelectric consequence. The strain gage burden cell is the largely used among the all sorts of burden cells. Therefore, when we say â€Å" burden cell, † we are largely mentioning to strive gauge burden cells. Although there are many other measurement devices, such as piezoelectric detectors, magnetostrictive detectors, electrical capacity detector and other detectors.1.2-Types of Load cellsStrain gage burden cells Tension burden cells Pneumatic burden cells Hydraulic burden cells Shear Load Cells Compression Load Cells Bending Load Cells Ringing Torsion Load Cells Pancake Load Cells Single Point Load Cells1.3-Strain Gauge Load CellsThis is a type of burden cell which is usage to mensurate the degree of any storage vas.1.3.1-Working ruleWhen force per unit area is applied on a music director its length alterations due to which opposition of the music director alterations and relation to the alteration in opposition show unit displays the alteration in degree.1.3.2-Construction and workingA strain gage is consists of a long length music director which is arranged in zig-zag manner on the flexible membrane which is exposed to the applied force per unit area country. This music director is connected in a wheat rock span as a resistance and when force per unit area or weight is applied on the membrane which is connected to the music director it gets stretched and due to stretching the length of the music director alterations and due to alter in length the opposition of the music director additions. These are normally four or a multiple of four, are connected into a wheat rock span constellation in order to change over the really little alteration in the opposition into the suited electrical signal. As these gages are combination of mechanical and electrical constituents so the mechanical parts are located at the site but electrical parts are in the control suites due to their environmental and temperature sensitivenesss. And the wires used for the transmittal of the signals besides have their ain opposition so that opposition besides considered during their building. The accommodation and arrangement of the strain gage burden cell in the wheat rock span and its working phenomena is shown in the undermentioned diagrams. Strain gage burden cells are placed at the underside of the vass largely to mensurate the degree of the column or vas. 00204.png Figure Figure 00205.png1.3.3-AdvantagesStrain gage burden cells are used in automotive industry to look into the structural public presentations of the stuff used in doors, goons, short pantss etc. Strain gage burden cells can be usage for weighing intents. Strain gage burden cells can besides be usage for stuff testing in procedure industry besides. Strain gage burden cells are besides used in tensile trial machines as a major constituent. Strain gage burden cells truth is 0.07 % of the rated capacity Strain gage burden cells can be used for both enlargement and compaction. Strain gage burden cells are less dearly-won so largely used in the industry.1.3.4-DisadvantagesStrain gage burden cells require uninterrupted electric energy for the production and show of signals. Strain gage burden cells besides requires an elaboration circuit for the coevals of end product show because the signals produced by the gage itself are of really much low electromotive force about in milli Vs. Strain gage burden cells can non be used for the force per unit area measuring of extremely reactive or caustic stuffs because they can damage the gage. Strain gage burden cells can non be used for the measuring of really high force per unit area if the stop usage is of plastic.1.4-Tension Load CellsThis is another type of burden cell which is besides usage to step to the degree.1.4.1-Working PrincipleIt consists of a vibrating wire transducer, fixed in a thick-vessel metallic cylinder, designed to supply a extremely stable and sensitive agencies of supervising tensile tonss in weighing systems, like procedure weighing systems and batch systems. As the applied burden additions on the burden cells the force on the internal vibrating wire besides increases by altering its tenseness, and therefore the resonating frequence of the vibrating wire. The frequence is measured and relative to the applied weight.1.4.2-Construction and workingThe chief portion of this burden cell is strain gauged stop which is for good secured in the transducer shell. The transducer is fitted with a metallic oculus leting in line connexion to the deliberation system, and a metallic hook, attached to the sensitive stop, provides a agency by which weight is applied in a suspended manner. The burden cell is vented to the ambiance to extinguish barometric effects for the upper limit or optimal truth. The signal overseas telegram which is attached to the burden cell is connected with the control room where these signals can be monitored. Figure There are besides some Thermistors placed inside its shell which are used to mensurate the temperature of the working fluid or vas. Degree centigrade: UsersAlY RaZaAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.WordUntitled.png1.4.3-AdvantagesThe chief advantage of the tenseness burden cell is that it is extremely sensitive and stable. As it is a vibrating component wire detector and its end product is frequency so it is non affected by the alteration in the overseas telegram opposition and therefore long signal overseas telegrams are non jobs. The frequence of the vibrating wire is measured by either the portable read-out box or informations lumberman. So it can give more accurate readings. The end product signal scopes in the electromotive force from 0 to 5 Vs so there is no elaboration unit required and therefore the cost lessenings. The rated capacity of the tortuosity burden cell is from 10 kilograms to 15 kilograms. The truth of the tortuosity burden cells is A ±0.1 % The temperature ranges for the working or operation of the tortuosity burden cells is -20A °C to +80A °C. Such types of transducers have about zero impetus and have besides really low consequence of temperature on its truth.1.4.4-DisadvantagesThis type of burden cells can non be used for high temperature fluids to happen degree or weight of fluid incorporating column. This type of burden cells can non besides be used for high capacities or for big armored combat vehicles column or weight measurings. This type of burden cell is extremely affected by the high temperatures due to its sensitive nature of the detection wire.1.5-Pneumatic Load CellsThis is another type of burden cells which are usage to mensurate the weight in the industry and these are used for low capacity.1.5.1-Working PrincipleThis type of burden cells works on â€Å" the force-balance rule. †1.5.2-The Force-Balance PrincipleThe inertial force produced by a seismal land gesture shifts the mass from its original equilibrium place, and the alteration in place or speed of the mass is so interpreted into an electric signal. This rule is for low scope burden cells. For long scope burden cells the inertial force is balanced with an electrically generated force so that the mass moves every bit low as possible.1.5.3-Working of pneumatic burden cellThis sort of burden cells consist of a detection component which is exposed to the site or the vas of which force per unit area or lying unstable weight is to be measured. And in this sort of burden cell the force reassigning medium is air as comparison to the any other fluid in instance of hydraulic burden cell. When force is applied by the lying fluid on the feeling portion of the burden cell it transfers this force to the inside air and so this force is applied on the potentiometer which is placed in the wheat rock span. As the force is applied on the feeling portion of the burden cell the opposition of the variable opposition potentiometer alterations due to this force and therefore the possible equilibrium between the oppositions is disturbed and this shows the magnitude of the applied force on the feeling component by exposing it on the show unit. Figure pneumatic.gif Another technique which is largely used in such sort of burden cells is the use of the piezoelectric crystals. In this sort the detection component transportations applied force to the interior fluid ( air ) and it imparts this force on the crystal. And due to the application of the applied force on the crystal by agencies of air its construction gets disturbed and due to disturbance in the construction the possible across the crystal alterations and this alteration in the possible across the crystal is detected by the voltmeter and so this electromotive force is converted into weight of force units and displayed on the exposing unit. Most of the clip wheat rock span is used for this sort of burden cell and there is merely variable resistance largely used while other resistances in the wheat rock span are of fixed opposition.1.5.4-AdvantagesThey are largely used on smaller tons when safety and protection are of premier concern. They are better in truth as comparison to the hydraulic burden cells because there is no alteration in the denseness and truth of the fluid being used for the transportation of applied force. They besides preferred on the hydraulic burden cells because there is no usage of liquid in these sorts of burden cells. These types of burden cells are inherently explosion cogent evidence and insensitive to temperature fluctuations. As they contain no fluids so there is no job of taint of the procedure if the stop gets ruptured. Pneumatic burden cells are besides used to mensurate little weights that depend upon cleanliness and safety.1.5.5-DisadvantagesThe chief disadvantage of these types of burden cells is that they can non be used for high measure measuring. Although they are really resistive to the temperature effects but their truth even acquire disturbed at really high temperature.1.6-Hydraulic Load CellsThis is another type of burden cells which are used to mensurate the magnitude of the applied force and their transition to the electric signals and its digital show.1.6.1-Working PrincipleThis type of burden cells besides work on â€Å" the force-balance rule. † The difference between the pneumatic burden cell and hydraulic burden cell is merely the transferring medium. In instance of pneumatic burden cell the force reassigning medium is air while in hydraulic burden cells the force reassigning medium is largely liquid or incompressible oil which is besides known as break oil.1.6.2-Construction and workingHydraulic burden cell consists of a fluid which act as a force reassigning medium and a piezoelectric crystal which is usage to change over this applied force into possible difference and so there is an agreement for the transition of this possible difference in footings of weight or force per unit area. There is a stop which is usage to feel the force exerted from the external side and the whole shell in which this complete cell is enclosed. When the force per unit area or weight by the vas or column is applied on the stop of the burden cell it sense that force and so transportations this force to the fluid which is filled in the shell of this burden cell. Then this force is transferred to the piezoelectric crystal by the fluid or oil and this oil transfers this force by the Pascal ‘s jurisprudence. So when the force is transferred by the oil it disturbs the internal construction of the piezoelectric crystal and due to this alteration in the construction of the piezoelectric crystal a possible difference is generated across the piezoelectric crystal. This possible difference is detected by the electric sensor and electric signal is transferred to the show unit to expose the magnitude of the applied force, weight or force per unit area. Figure Hydraulic.gif1.6.3-AdvantagesThese are largely use to happen the weight of the stuff in the storage armored combat vehicles, bin or hopper. The end product given by these types of burden cells is additive and largely unaffected by the sum of the filling fluid ( oil ) or by its temperature. If the hydraulic burden cells have been decently installed and calibrated so truth is largely within 0.25 % full graduated table or better and this is acceptable for most procedure weighing applications. As these types of burden cells have no electrical constituents therefore it is ideal for usage in risky or caustic countries. For more accurate measuring, the weight of the armored combat vehicle should be obtained by turn uping a burden cell at different points and summing their end products.1.6.4-DisadvantagesOne disadvantage of this type of burden cell is that the elastomeric stop limits the maximal force that can be applied on the Piston or stop to about 1,000 psig. Electronic pari-mutuel machine is required in instance of acquiring more accurate reading by summing the readings of the single burden cells. Another disadvantage of hydraulic burden cell is that they are expensive and are complex to utilize.1.7-Shear Load CellsThis is another type of burden cells which is usage to mensurate the weight or the degree of the column incorporating fluid or some stuff.1.7.1-Working PrincipleThis type of burden cells works on the shear of the web. A web of an elastic stuff is inserted at some degree in the vas or storage armored combat vehicle and a shear emphasis exerted by the unstable column stretches the web harmonizing to the burden of the unstable column. Therefore by mensurating the shear emphasis the degree or weight of the fluid in a column can be measured.1.7.2-Construction and workingThis type of burden cells consists of a web and a frame which is movable and the web is fixed with this frame. There are strain gages which are straight connected with this web and step the weight or degree of the column by mensurating the shear emphasis exerted by the liquid nowadays in the column on the web. As the web is inserted in the liquid column, liquid exerts the force on this web as this web is stretchy and elastic so it gets stretched and this stretched province of the web is sensed by the strain gages. This web is inserted in the liquid column perpendicular to the axis of the column. Then strain gages transfers the mensural value of the shear emphasis exerted by the tallness of the liquid column to the electrical transducers which converts it into electrical signals and so transmits it to the show unit to expose the mensural value of the weight in footings of degree or force per unit area as we required. Figure1.7.3-AdvantagesShear burden cells are popular now for all type of mediums and for high capacities. Shear-web is non limited to merely beam constellations. Shear-web detection component is besides being used by high capacity BSP and USP in a more complex manner. Shear burden cell engineering is besides being used in rearward transducers. Shear tonss cells can readily be sealed and can be protected from the environmental effects.1.7.4-DisadvantagesShear burden cells have comparatively little sensitiveness at the burden point so can non be used for little graduated table measurings. Shear burden cells are expensive as comparison to the strain gages. Shear burden cells are delicate merely because of the web which is really delicate and can be easy damage due to overload fro few minutes even.

The Differences Between Communism and Socialism

The Differences Between Communism and Socialism The difference between communism and socialism is not conveniently clear-cut. The two terms are often used interchangeably, but these economic and political theories are not the same. Both communism and socialism arose from protests against the exploitation of the working class during the Industrial Revolution. While applications of their economic and social policies vary, several modern countries- all ideologically opposed to capitalism- are perceived as either communist or socialist. In order to understand contemporary political debates, its important to know the similarities and the differences between communism and socialism. Communism vs. Socialism In both communism and socialism, the people own the factors of economic production. The main difference is that under communism, most property and economic resources are owned and controlled by the state (rather than individual citizens); by contrast, under socialism, all citizens share equally in all economic resources as allocated by a democratically-elected government. This difference and others are outlined in the table below. Communism vs. Socialism Attribute Communism Socialism Basic Philosophy From each according to his ability, to each according to his needs. From each according to his ability, to each according to his contribution. Economy Planned By Central government Central government Ownership of Economic Resources All economic resources are publicly owned and controlled by the government. Individuals hold no personal property or assets. Individuals own personal property but all industrial and production capacity is communally owned and managed by a democratically elected government. Distribution of Economic Production Production is intended to meet all basic human needs and is distributed to the people at no charge. Production is intended to meet individual and societal needs and distributed according to individual ability and contribution. Class Distinction Class is abolished. The ability to earn more than other workers is almost nonexistent. Classes exist but differences are diminished. It is possible for some people to earn more than others. Religion Religion is effectively abolished. Freedom of religion is allowed. Key Similarities Communism and socialism both grew out of grass-roots opposition to the exploitation of workers by wealthy businesses during the Industrial Revolution. Both assume that all goods and services will be produced by government-controlled institutions or collective organizations rather than by privately-owned businesses. In addition, the central government is mainly responsible for all aspects of economic planning, including matters of supply and demand. Key Differences Under communism, the people are compensated or provided for based on their needs. In a pure communist society, the government provides most or all food, clothing, housing and other necessities based on what it considers the needs of the people. Socialism is based on the premise the people will be compensated based on the level of their individual contribution to the economy. Effort and innovation are thus rewarded under socialism. Pure Communism Definition Pure communism is an economic, political, and social system in which most or all property and resources are collectively owned by a class-free society rather than by individual citizens. According to the theory developed by German philosopher, economist, and political theorist Karl Marx in his classic 1848 book, â€Å"The Communist Manifesto,† pure communism results in a society in which all people are equal and there is no need for money or the accumulation of individual wealth. There is no private ownership of economic resources, with a central government controlling all facets of production. Economic output is distributed according to the needs of the people. Social friction between white and blue collar workers and between rural and urban cultures will be eliminated, freeing each person to achieve his or her highest human potential. Under pure communism, the central government provides the people with all basic necessitates, such as food, housing, education, and medical care, thus allowing the people to share equally from the benefits of collective labor. Free access to these necessities depends on constant advances in technology contributing to ever-greater production. In 1875, Marx coined the phrase used to summarize communism, â€Å"From each according to his ability, to each according to his needs.† Pure Socialism Definition Pure socialism is an economic system under which each individual- through a democratically elected government- is given an equal share of the four factors or economic production: labor, entrepreneurship, capital goods, and natural resources. In essence, socialism is based on the assumption that all people naturally want to cooperate, but are restrained from doing so by the competitive nature of capitalism. Socialism is an economic system where everyone in society equally owns the factors of production. The ownership is acquired through a democratically elected government. It could also be a cooperative or public corporation in which everyone owns shares. Again, the four factors of production under socialism are labor, entrepreneurship, capital goods, and natural resources. As in a command economy, the socialist government employs centralize planning to allocate resources based on both the needs of individuals and society as a whole. Economic output is distributed according to each individual’s ability and level of contribution. In 1980, American author and sociologist Gregory Paul paid homage to Marx in coining the phrase commonly used to describe socialism, â€Å"From each according to his ability, to each according to his contribution.†Ã‚   What Is a Socialist Democracy? Democratic socialism is an economic, social, and political ideology holding that while both the society and economy should be run democratically, they should be dedicated to meeting the needs of the people as a whole, rather than encouraging individual prosperity as in capitalism. Democratic socialists advocate the transition of society from capitalism to socialism through existing participatory democratic processes, rather than revolution as characterized by orthodox Marxism. Universally-used services, such as housing, utilities, mass transit, and health care are distributed by the government, while consumer goods are distributed by a capitalistic free market.   The latter half of the 20th century saw the emergence of a more moderate version of socialist democracy advocating a mixture of socialist and capitalist control of all means of economic production supplemented by extensive social welfare programs to help provide the basic needs of the people. What is Green Socialism   As a recent outgrowth of the environmental movement and the climate change debate, green socialism or â€Å"eco-socialism† places its economic emphasis on the maintenance and utilization of natural resources. This is achieved largely through government ownership of the largest, most resource consumptive corporations. The use of â€Å"green† resources, such as renewable energy, public transit, and locally sourced food is emphasized or mandated. Economic production focuses on meeting the basic needs of the people, rather than a wasteful excess of unneeded consumer goods. Green socialism often offers a guaranteed minimum livable income to all citizens regardless of their employment status. Communist Countries It is difficult to classify countries as being either communist or socialist. Several countries, while ruled by the Communist Party, declare themselves to be socialist states and employ many aspects of socialist economic and social policy. Three countries typically considered communist states- mainly due to their political structure- are Cuba, China, and North Korea. China The Communist Party of China owns and strictly controls all industry, which operates solely to generate profits for the government through its successful and growing export of consumer goods. Health care and primary through higher education are run by the government and provided free of charge to the people. However, housing and property development operate under a highly competitive capitalist system. Cuba   The Communist Party of Cuba owns and operates most industries, and most of the people work for the state. Government-controlled health care and primary through higher education are provided free. Housing is either free or heavily subsidized by the government. North Korea Ruled by the Communist Party until 1946, North Korea now operates under a â€Å"Socialist Constitution of the Democratic Peoples Republic of Korea.† However, the government owns and control of all farmland, workers, and food distribution channels. Today, the government provides universal health and education for all citizens. Private ownership of property is forbidden. Instead, the government grants people the right to government-owned and assigned homes. Socialist Countries Once again, most modern countries that identify themselves to be socialist may not strictly follow the economic or social systems associated with pure socialism. Instead, most countries generally considered socialist actually employ the policies of democratic socialism. Norway, Sweden, and Denmark all employ similar predominantly socialist systems. The democratically chosen governments of all three countries provide free health care, education, and lifetime retirement income. As a result, however, their citizens pay some of the world’s highest taxes. All three countries also have highly successful capitalist sectors. With most of their needs provided by their governments, the people see little need to accumulate wealth. As a result, about 10% of the people hold more than 65 percent of each nation’s wealth.

Using Multiple Main Classes in Java

Using Multiple Main Classes in Java Normally at the outset of learning the Java programming language, there will be a number of code examples that are useful to compile and run to fully understand them. When using an IDE like NetBeans its easy to fall into the trap of creating a new project every time for each new piece of code. However, it can all happen in one project. Creating a Code Example Project A NetBeans project contains the classes needed to build a Java application. The application uses the main class as the starting point for the execution of the Java code. In fact, in a new Java application project created by NetBeans only one class included - the main class contained within the Main.java file. Go ahead and make a new project in NetBeans and called it CodeExamples. Lets say I want to try programming some Java code to output the result of adding 2 2. Put the following code into the main method: public static void main(String[] args) {int result 2 2;System.out.println(result);} When the application is compiled and executed the output printed is 4. Now, if I want to try out another piece of Java code I have two choices, I can either overwrite the code in the main class or I can put it in another main class. Multiple Main Classes NetBeans projects can have more than one main class and its easy to specify the main class an application should run. This allows a programmer to switch between any number of main classes within the same application. Only the code in one of the main classes will be executed, effectively making each class independent of each other. Note: This is not usual in a standard Java application. All it needs is one main class as a starting point for the execution of the code. Remember this is a tip for running multiple code examples within one project. Lets add a new main class to the CodeSnippets project. From the File menu choose New File. In the New File wizard pick the Java Main Class file type (its in the Java category). Click Next. Name the file example1 and click Finish. In the example1 class add the following code to the main method: public static void main(String[] args) {System.out.println(Four);} Now, compile and run the application. The output will still be 4. This is because the project is still set up to use the Main class as its main class. To change the main class being used, go to the File menu and choose Project Properties. This dialog gives all the options that can be changed in a NetBeans project. Click on the Run category. On this page, there is a Main-Class option. Currently, it is set to codeexamples.Main (i.e., the Main.java class). By clicking the Browse button to the right, a pop-up window will appear with all the main classes that are in the CodeExamples project. Choose codeexamples.example1 and click Select Main Class. Click OK on the Project Properties dialog. Compile and run the application again. The output will now be four because the main class being used is now example1.java. Using this approach its easy to try out lots of different Java code examples and keep them all in one NetBeans project. but still be able to compile and run them independent of each other.

Procedures in Collecting Forensic Evidence Essay

Procedures in Collecting Forensic Evidence - Essay Example The auditor would first check the design of the system and if he is satisfied with the design then he goes on checking the operation of the internal control system. The auditor must make inquiry of the management of the reasons for which the pervious auditor withdraws from the assignment. Management should be inquired as to the facts of not allowing the current auditor contacting the previous auditor. There are certain chances of irregularity in the financial statement or the withdrawal of the auditor may also indicate fraud. The auditor use both statistical techniques and non-statistical technique to select sample from any given population. When using the non-statistical sampling auditor uses his professional judgment to select the sample. The purpose of this type of sampling is to achieve satisfactory basis for the auditor to draw conclusion about the population. It is essential for the auditor to select a sample that represents population to avoid bias. The most common methods of sample selection are described below; In this type of sampling population is divided by a sample size to obtain s sampling interval. For example the auditor may select every 25th item from the population. The auditor should be careful if the population units are not structured in that way that the sample population represents a particular pattern (Pickett, 2006). This is the sampling technique in which the auditor selects a sample without following any structured techniques. With the use of this sampling the auditor avoid any biased selection, but it has no basis to justify the reason for which any particular item was selected. This sampling method is not appropriate when statistical sampling is used. In this method the auditor selects samples of contiguous items from the population. This type of sampling is not normally used in audit because the population is structured. It is only effective in

Self Compacting Concrete Essay Example | Topics and Well Written Essays - 250 words

Self Compacting Concrete - Essay Example 26). SCC can be used in most applications where traditionally vibrated concrete is used. It is suitable for high performance, densely reinforced structures as well as for less demanding unreinforced applications for instance the backfill (Petersson, et al., 2000, pg. 3). SCC can be fibre reinforced and is equally applicable for in situ construction as well in precasting. It has the capability to fill formwork and encapsulate and condense reinforcing bars only through the action of gravity and with maintained homogeneity. This ability is achieved by designing the concrete in such a way that it gains suitable inherent rheological properties. These properties are achieved through by not subjecting the concrete to any exterior energy input from vibrators, tampering or comparable actions. The predominant reason for the development of SCC has been the concern for reduced durability that is cause by inadequate homogeneity of the cast concretes. However, SCC has also been used to improve the quality of concrete work and to allow for the ability for automation of the construction work as well as improve the working conditions on construction sites (Cleland, et al., 1996, pg. 483). Other benefits of SCC over other forms of concrete include, it can be placed at a speedier and swifter rate without the need for mechanical vibration and with reduced screeding and this results to savings in placement costs, there is better-quality and more uniform and consistent architectural surface finish with minimal to no remedial surface work, there is enhanced consolidation around reinforcement and bond with reinforcement, it improved pumpability and is labor savings, it shortens constructions periods which translates to lower construction costs and minimised the traffic of ready mixed t rucks and pumps for the period of placement and finally increased work environment safety by doing away with the
