radar-the world communicates essays

radar-the world communicates essays Current Technology and Advances Made Radar first began in 1930 when two American scientists realised its military value. Its first major application was in 1940 when the British had developed radar to such a degree that they were very successful in detecting and shooting down many enemy aircraft during WWII. Since then Radar has made a lot of advances and has spread into many different fields such as tracking aeroplane traffic, mapping, weather forecasting and one of its very important uses in police radar and speed cameras. In the late 1950s the police introduced the first technologies to kerb the ever-increasing fatality rate on the N.S.W roads. They introduced the first speed detection device called the Pie Radar (Radio Detection and Ranging) which had an antenna about the size of a 20-litre drum, because of its size and the power required to run it, it had to be carried around in the back of a Ute which had to be kept running to power the radar. These original radars were not really a solution to the problem as they were not practical or accurate. In 1968 a new radar called the S5 was put to the test and showed to be more salubrious than previous models as it was smaller and much easier to use but in 1971 the S5 radar lost a challenge in court and it was proved that the manufacturer couldnt verify their own radar, this was the end of the S5. The polices radar of today is called the Silver Eagle Traffic radar it can be used both in a stationary position as well as in a moving vehicle as it is contr olled by a Doppler based microprocessor. The other modern day speed camera is the Traffixpak Speedshot, which can tell the difference between different vehicles travelling in the same direction as well as calculating the speed of vehicles travelling in both directions this system can also be modified to digital imaging in the future. The newest radar instrument, which was introduced in 1997, is c ...

Case Study Of Collin’s ATM System Samples

The business information system is described as a system that integrates information technology components, people and overall business functions. The business information system helps to bring information technology components and business functions together to establish effective interaction among the components to provide organizational growth (Kharchenko & Chynchenko, 2013). The effectiveness of business information system in this report is discussed in this report with reference to a case study. The chosen case study is Collin’s ATM system. The description of Collin’s ATM system through system vision document is provided in this report. The purpose of this report is to analyse the given cases study using business information system approach. The outline of this report is system vision document, resources required, stakeholder map and risks of the project. The system vision document consists of problem description, proposed outcome, system capabilities and business benefits. The problem descriptions of Collin’s ATM Bank are given as follows. There are different kinds of consumers who want easy access to banking system and services such as deposit or withdrawal, from any part of the world. This service is provided by a system called ATM which is used commonly in today’s scenario (Kamal et al., 2015). ATM is commonly used for withdrawal, mini statements and balance checking for an individual account reducing the human effort. Hence, Collin’s ATM Bank requires an ATM system to facilitate their customers by providing easy banking activities. The Collin’s ATM Bank requires the ATM to have a card reader for reading ATM cards. The other requirements are a cash dispenser, a display, a printing feature to print details of transaction and to deposit cash/cheques a chute feature is required. The proposed outcome of Collin’s ATM system is the key requirements, the company needs. The key requirements of the Collin’s ATM system are as follows. The first is to assist one customer at a single time. The second is recognition of card by the corresponding bank. The third is to verify the entered pin. The fourth is to select the type of account; customer has (Montefusco et al., 2016). The fifth is to select the type of transaction such as withdrawal, deposit, transfer, checking account balance or printing mini statements. The sixth is to generate report after transaction and facilitate the corresponding bank to provide regular updates to identify the flow of cash from a corresponding bank. The system capabilities of ATM system are various and hence, the ATM system is the most common one for every banking industry. The capabilities are as follows. The ATM system provides benefit of doing transaction 24/7 hours (Ahmad, Rifen & Wahab, 2016). The human effort is reduced which is the most beneficial capability of this system. The bank customers leverage convenience to use this system without the need of going to bank. This system requires small place to install and hence more convenient in farther and remote areas where customers have to travel to the bank (De Gramatica et al., 2015). The ATM system provides new notes rather than the soiled ones to the customer. This system minimizes the hassle in transaction process to provide a quick and fast transaction. The ATM system provides paperless process until and unless customers need a paper receipt or mini statement. The ATM system is beneficial for making customer’s daily work easy. However, this system too comes with some major issues and their as follows. There are issue with ATM card that it can be cloned for fraud activities. There are some cases regarding fake ATM systems. The ATM operates on a network and hence if the ATM is out of service then no transaction process can occur (Patriarca, 2016). There is no guarantee that ATM system will have cash when a customer needs. The shortage of amount is handled by the bank if no amount of cash is left in the system. The above paragraph shows the system capabilities of ATM system which is beneficial for the business growth of a bank such as Collin’s ATM Bank (Ball et al., 2017). Therefore, the below points shows the benefits of ATM system provide for organizational growth. The resources for the ATM system are of various kinds of activities that the system offers such as transaction, insertion of pin number, screen and other activities (De Gramatica et al., 2015). The resources required as per the need of Collin’s ATM system requirements along with some additional resources are given below. Card Reader- The card reader is an essential requirement for the system. The card reader is used to read the various kinds of cards to access its information (Onyesolu & Okpala, 2017). The various kinds of cards are processed by the card reader to get information and proceed according to the action provided by the card holder. The card is swiped in the system to be accessed by the card reader. Display Screen- The display screen is similar to a television or computer screen where information or menus are shown to the customers (Mandari & Koloseni, 2016). The steps for transaction process whether it is withdrawal or deposit, both are shown in the screen to facilitate the process for the customer. The most widely used display screens are CRT or LCD screen. Keypad- The keypad in the system provides insertion of details such as personal identification number (pin) of the card or amount of cash whether for depositing or withdrawal. The keypad generally consists of 48 keys (Verma, 2014). The pin number in the system is entered in an encrypted form through keypad to prevent any fraud activities. The keypad comes with this feature of encryption which is used only for pin number details. Speaker- The speaker in the system provides information when any error occurs or any wrong key is pressed against the activity shown in the display screen. Printers- The printers are used only for the purpose of printing receipts of transactions, mini statements and balance enquiry (Sharma et al., 2017). The receipt provides information regarding the transaction occurred. An example is, a receipt for withdrawal generally contains date and time of transaction, account number (in encrypted format), amount withdrawn and total balance. There are three major stakeholders related to ATM system and they are are primary, secondary and tertiary. The primary stakeholders are the customers who do transaction using the ATM system. The banks are considered as secondary stakeholder because bank act as a platform through which transaction occurs. The tertiary stakeholders are manufacturer of ATM system who deals with the different kinds of issues related with ATM system (Kavitha, 2015). These stakeholders have large number of advantages and limitations regarding the ATM system. The benefits are using ATM for regular transactions at high speed and technical errors are reduced through this system. This benefit is related to customers who are responsible for using the ATM for transaction. The benefit for secondary customer is that they can easily get extra amount of cash as interest from several customers when they do transaction. The easy and fast transaction is an essential part of generating revenue for banks. The customers w ill also likely to suggest it to other customers and recommend to the banks to build more ATM systems. The risks of the project to implement ATM system are various. The major issues are fraud related to currency, attacks related to physical and logical types of attack. These three are the major and common attacks that may occur and there is a need to prevent these attacks (Kavitha, 2015). The security of ATM system consists of three major areas and they are currency protection, different types of logical security and physical security. The below paragraph describe the fraud related to cards and currencies. There are many frauds nowadays related to cards and currency. The attack occurs on cards and currency where the details of cards and cash are stole by the attackers. These details are then misused for fraud activities of withdrawal (Martins, Oliveira & Popovi?, 2014). The type of attacks in ATM occurs are skimming, fishing of cards and currency tapping which are common nowadays. The stealing of card and currency details affects the customers badly resulting in financial loss for customers as well as banks.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The above discussions conclude that a business information system is a necessary part for an organization before starting of any project. The report shows the analysis of business information systems through a case study of an ATM system. The development of ATM system is thoroughly analysed to provide an overview of the effectiveness of the business information system. The system vision document briefly describes the aspects of ATM system that will be required to develop the system. The report focuses on how ATM system can be built with the provided resources, associate stakeholders and considered risks to prevent. Therefore, it can be concluded that system vision document with reference to business information system provides an overview of any project. Ahmad, N., Rifen, A. A. M., & Wahab, M. H. A.

Outline - Essay Example You have probably come across it in your studies or seen it in the media, at one time or another- am talking about the City Lagos Nigeria. B. Adaptation: Most governments would want to develop and grow their cities at some point or another. Learning the best strategy of growing the cities would not only help countries to develop effective cities but also to decentralize power to other areas and to reduce many incidents of corruption that come with centralized systems of governance. C. Credibility: Centralization of power often results into growth of failed and weak states. In such countries, power and wealth is vested among the few individuals and systems, which always fail to serve their intended purpose. Absence of effective and credible governance often leave many states, towns and cities in a sorry and destitute state and the inhabitants are left to languish in poverty. To avoid this scenario, I have gathered adequate information regarding the strategy that the City Lagos Nigeria used to make its sudden paradigm shift that I believe would guide other States at the verge of collapsing. D. Enumerated preview: This research paper provides three main lessons that can be learned by failed states from the turnaround made by the City Lagos Nigeria that would enable them to improve in governance- embrace democracy, embrace diversity, and focus on effective devolution. II. Diversity relates to the differences that exist between people and their demographic surrounding. Cities that are able to utilize diversity creatively and innovatively will be able to navigate through most of the governance challenges (Purcell, 2013, 16). 3. Geographical diversity and spread in terms of settlements also promotes effective governance since the people who posses most of the wealth and authority would be influenced if their neighborhoods were affected by the urban problems. Transition: Embracing democratic governance and diversity can play a great role in promoting growth

Case summary Assignment Example | Topics and Well Written Essays - 500 words

Case summary - Assignment Example Most customers could find their way in since they have in mind that all the items they may wish to have are available hence increasing the number of customers thereby making huge profits. The cool music system in supermarket industries makes customers to feel much entertained while carrying out their shopping. However, almost all supermarket industries provide their customers with a wide range of items at their points. This enables most customers to find their way in. Trader Joe came up with a unique way of promoting his business nature by producing products which were not offered initially by other supermarkets such as black rice, whole bean coffees and sprouted wheat bread. Trader Joe later offered an extensive line of the private label items with brand names such as Trader Ming’s, Trader Jose and Trader Joe among others. All the labels were bearing the name ‘’Trader’’. This is an indication that he didn’t want to lose this title and popularity. On the other hand, Trader Joe stores could be found in old trip malls locations which maintained footprints. However, the nature of the prices was favorable and most of the customers could find their way in more especially during busy Saturday morning. Trader Joe also was paying his staff members more than what they were expecting including the retirement payments. Such offers could act as motives to the workers hence could make them to work open heartedly during their time of work. Trader Joe also organized the firm to offer health care benefits to all part time employees (Nicholas 67). Despite all the success, Trader Joe services attracted some imitators such as the Tesco which was the third largest retailer launched some small nearby markets in western United States. The firm drew some concepts which created competition between them (Nicholas 59). Trader Joe on the other side did not invest in technology within the store.

If I Had A Choice By Walt Whitan Essay Example for Free

If I Had A Choice By Walt Whitan Essay Wave resemblance in Walt Whitmans If I Had the Choice Although not rhythmically or metrically consistent throughout, Walt Whitmans poem If I Had the Choice is very consistent in its attempt to resemble the characteristics, specifically the waves, of the sea; whether read, heard, or seen, the poems adaptation to a waves nature is clearly evident. Whitmans use of repeated, but not uniform, rhythm in the poem exposes the up and down nature of waves, while the sudden, drastic change in rhythm helps depict the crashing of a wave. The metrical variation in the poem similarly attributes to the resemblance of a wave, for it goes hand in hand with the length of each line, giving the poem the physical characteristics of a wave. While the there is no metrical consistency throughout the poem (probably done because no two waves are identically alike), there is a noticeable pattern and consistency in the rhythm of the poem. The consecutive use of iambs in the first five lines of the poem help to not only emphasize the steady motion of the sea, but more importantly to give the poem a sense of the up and down motion of the waves in the sea; the pattern of unstressed/stressed/unstressed/stressed syllables in every line is very similar to the up and down undulation of a wave. The shift from the iambic rhythm in lines one through five to a loud, sudden spondee in line six clearly depicts the image of a wave crashing. The spondaic rhythm (stress/stress) of the first two words in line six, These, these, is an unexpected, drastic change from the prior unstressed/stressed pattern. Similar to the crashing of a wave, this change was drastic, and quick; it does not last long, hence the reason for the poems quick return to an iambic rhythm. The poems last three lines are once again consistently iambic; they are back to the quiet, pacific motion of waves in the sea. Just as the height of a wave affects the power of a wave, the meter of this poem affects its rhythm. Although there is no specific pattern for the number of feet per line in this poem, the meter is still greatly significant. When broken up iambically, the number of feet increase steadily from line one to four, until we reach line five, the longest (10 feet) line. The length of line five is significantly important in portraying the nature of waves; it is representative of the amplitude of a wave before it is about  to crash. Line five is ten feet long because it is followed by line six, the line in which there was a sudden rhythmical change, which portrayed the crashing of the wave. Once it crashes, the waves return to their prior size, just as the following lines of the poem go back to having the same range of feet as they did before line five. The alternating number of feet per line also allow the poems structure to resemble a wave; no two waves are similar in frequency (height) or amplitude (width), just as no two sentences of this poem are identical in length. As the lines approach the middle of the poem, they get longer, and then begin decreasing in size after they reached the longest point, line five. Since line five, the middle of the poem, is the longest line, when held sideways, this line is representative of the middle of a wave, its highest point right before it crashes. By using rhythm and meter skillfully, this poem is successful in imitating the rhythm of the sea, and the meter of the waves in the sea. In doing this, Whitman makes a very distinctive point; rhythm and meter affect each other, just as the height of a wave affects its crash. This relationship is evident whether one reads, sees or hears this poem.

Rwanda-Hutus and Tutsis Essay examples -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The triumph of evil occurs when good men do nothing.† This quote was said by the modern day political philosopher, Edmund Burke. This quote means that it is when good people don’t take action that bad things are allowed to happen. This relates to the recent genocide in Rwanda, when the Hutus massacred the Tutsis over a period of 100 days in the summer of 1994. Three major ways in which good men did nothing is the UN’s avoided action, the soldiers who abandoned the Tutsis, and the United States’ refusal to use the word â€Å"genocide,† and took no action to prevent it.   Ã‚  Ã‚  Ã‚  Ã‚  The UN did a large deal of procrastinating during the ordeal in Rwanda. At first, they wouldn’t even address that there was a problem, since no one stepped forward to say that there was one. They simply ignored it when the Rwanda ambassador told them that it was just a â€Å"civil war.† When the UN finally did admit to the fact that there was a problem, they made several promises of action. These promises were hollow. Few actions were actually made to defuse the problem. Now the UN had already broken its most sincere promise in only 50 years, to never allow the extermination of a single group of people. A promise made immediately following the end of the holocaust. All the UN really did was to send troops over there but that did little, the number of troop at one point was only a couple hundred, not nearly enough to stop the Hutu army. They also asked the US m...

Course Concept Redesign Coursework Example | Topics and Well Written Essays - 500 words

Course Concept Redesign - Coursework Example In addition, the new student can present their views by commenting on the video and get feedbacks from their fellow students. The search strategy used article databases in identifying the three sources on the concept of the greenhouse effect and climate change. In the first source, Reinfried and colleagues argue that it is difficult changing student’s everyday ideas of the greenhouse effect. The challenge that environmental education face is creating of instructional setting aimed to foster student’s conceptual understanding of the concept of the greenhouse effect. In facilitating students conceptual development regarding the greenhouse effect, it is critical to design learning materials that promote active cognitive learning and focused on achieving deep understanding of the concept. Reinfried et al., present in the article, a developed learning material based on the theory of understanding and reasoning. They compared the efficacy of the design with standard learning materials by using pre-, post and follow-up test. In examining the student’s understanding and knowledge acquisition o ver the three measurement test, Reinfried et al., used both qualitative and quantitative methods. The study outcome demonstrated that the group instructed according to the design focused on in-depth learning had better knowledge gains and retention compared to the group taught using standard learning materials. The strength of the article, therefore, is that it provides an instructional design that engages learners in high cognitive activities, which enhance deep conceptual understanding of the abstract and complex concept of the greenhouse effect. However, the article has a weakness in presenting a comparative study conducted for a long a duration of time because conceptual changes require much time to develop. In the second source, Ogden et al., points that the extent of climate change affects human health in a

WALMART'S OPERATIONS AND MANAGEMENT Essay Example | Topics and Well Written Essays - 500 words

WALMART'S OPERATIONS AND MANAGEMENT - Essay Example Market analysts are of the opinion that Walmart will retain its top position ("Turning Point"). With this trend, it seems that Walmart will definitely continue its dominance in the consumer market, at least in the foreseeable future. It definitely does not hve a problem with the number of retail stores it owns; in the United States alone,it has about 3900 retail outlets ("Annual Dividend"). Walmart is a very aggressive company, and is currently opening about 1.45 stores per day. Although Walmart shares have mostly not grown, it will most likely increase in the immediate future. In a research note, Edward Jones analyst David Powers said "We believe Wal-Mart's growth outlook remains favorable." Powers believes that by April this year, growth will accelerate to nearly 13%. (Van Riper) Walmart's main concern is its slow growth rate, although this seems to be a minor problem at the moment. In January 2006 Walmart's same-store sales growth was 4.7%, compared to the previous december's 2.2%. (Van Riper) It is interesting that Walmart has what is probably the world's largest computer database, in its 1000-person Information Systems Division. This database has a capacity of 460 terabytes, equivalent to almost half of the information on the Internet. (Bianco) Walmart is able to reduce payrol costs through automated generation and adjustment of work sch
