Understanding Computer Science 2019

Due to the fact that technology is constantly evolving, it can be difficult to pinpoint a solid definition for the specializations in the dynamic field of computer science. Computer Science has typically been understood as the study of solving computer problems. The elementary pursuits of computer science include the following questions: What are the computer problems that need solutions? How can the computer be made more efficient, faster, and accessible to scientists and the basic user? How can we utilize science to give computers a more viable artificial intelligence? The study of computer applications in a social context is called information technology. This involves information security, networking, and using computers as a sales, marketing or business tool. To really get an understanding of the many branches and terminology of the computer sciences is available in the educational realm. Examining the multitude of degrees at ones disposal related to the field can help to familiarize you with the business and the study of computer science. .u4dce2377373f947076314c874b1ead45 { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -moz-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -o-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); text-decoration:none; } .u4dce2377373f947076314c874b1ead45:active, .u4dce2377373f947076314c874b1ead45:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .u4dce2377373f947076314c874b1ead45 { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .u4dce2377373f947076314c874b1ead45 .ctaText { font-weight:bold; color:inherit; text-decoration:none; font-size: 16px; } .u4dce2377373f947076314c874b1ead45 .post Title { color:#000000; text-decoration: underline!important; font-size: 16px; } .u4dce2377373f947076314c874b1ead45:hover .postTitle { text-decoration: underline!important; } READ Getting Your Health Care Management EducationNumerous universities commit entire departments to computer science, and others create departments that stem from general computer science.

Indian and European Nations Free Essays

Nearly all European invaders as well as their descendants tried to submerge by suppressing their times of yore and by physical repression. The Indian nations relied on spoken means for the spread of history from one memorial cohort to the next, destined that the conclusion of their social constitution would obliterate their history, and thus complete the removal of their survival. Think of what ought to have come prior to the arrival of Europeans, which in several cases was even lost to Indians and the mass of distinctions with the tribes as they dealt with Europeans invaders. We will write a custom essay sample on Indian and European Nations or any similar topic only for you Order Now In the early 16th century, Indian nations were crisscrossed by the Spanish expeditions, turning over new traits, new influence, and the early amalgamation of priests and soldiers that commenced the progression of racial combination as well as Christianization a century prior to the English and French’s arrival in the New World. The colonization of Indian nations by the Europeans had overwhelming consequences for the indigenous people. Flanked by the diseases that were new to them brought by the assailants – Europe itself had simply gotten over an era of plagues as well as epidemics that killed no less than two thirds of its people, and the massacres and enslavement by the hands of the Spaniards. Spain explored and put down claim to the majority of the continent. Indian nations spoke their own languages; communication between Indians and Europeans suffered from differences, not just on a sole landfall, but throughout 500 years and even today. One understandable, yet concealed, source of resistance was the failure or repudiation of the Europeans, predominantly in the British Isles, to learn the Indian tongue. Indian words along with usages, in addition to many other languages such as Spanish, Greek, Italian, Hebrew, and German, came to supplement the English language and particularly the American tongue (Axtell, 2001, p30). The position of men and women among Indian grassroots showed a discrepancy more than among European nations. The distinctive characteristic of Indian civilization was the diversity of its population. In European standards, Indian nations at that time were astonishingly diverse regionally. This astounding diversity was in large part a creation of the technique that colonial Europe was initially settled. The reason possibly lay, throughout the 1400s and 1500s, with the regularity of relationships involving sexes that the Roman Catholic Church brought for centuries among the citizens of Central and Western Europe. The division of labor showed a discrepancy noticeably from a tribe, above among Europeans, however it was found that it lacked class system as well as social estates of Europe, there was greater parity and uniformity of role among lower and higher orders of women and men. The establishment of Indian nations is in fact the longest and exhaustive structure of any independent lands in the world. India, in particular, has a quasi-federal type of regime and a bicameral congress functioning under a Westminster-style parliamentary scheme (Iverson, 1992, p34). Since its sovereignty in 1947, these Indian nations maintained amiable and cordial connections with most countries. The history of Indian nations experienced colonial dependencies within the western hemisphere created by the European countries causing diversity in population, problems in geography and establishments of institutions. European nations increased colonies in Indian nations for several reasons, but mostly to create income. They made use of colonies to give raw materials for trade serving as markets for polished and refined products. These systems encouraged religious toleration, diplomat government, economic development as well as cultural diversity. However, the historical policies of Europeans that carry on bureaucracies in and out of Indian nations suppress tribal management and prop up reliance. Indian peoples will stay in a dependent affiliation and the poverty will provide confirmation of the historic abandonment of the nations’ original people so long as regime (Salisbury, 2000, p18): holds back the economic and political growth of the Indian peoples, deprives them to quality education, disregard cultural needs of Indians, and raises bureaucratic barriers to the recognition of Indian tribes as humans and Indian peoples as part of history.

Performance review free essay sample

2. Determine an overall employee performance score based on information found on the appraisal form and components of the job description. Answer:There are two parts of the overall employee performance score. One parts is the open-end sections and the other part is the quantitative information. They are using weights of 0. 7(quantitative) and 0. 3(open-end) to combine to the overall score. And in the quantitative section, they total score also will be calculated by the weight method. 3. Select an appropriate time period to document performance as part of a performance review. Answer: Conduct semiannual reviews and complete the appraisal forms toward the end of the fiscal year. one review would be completed halfway through the fiscal year and the other one toward the end of the fiscal year. Adopting this approach leads to the completion of the appraisal form for all employees at about the same time, thereby facilitating cross-employee comparisons as well as the distribution of rewards. An additional advantage of following the fiscal year cycle is that individual goal setting can be more easily tied to corporate goal setting because most companies align their goal cycle with their fiscal year. This helps employees synchronize their work and objectives with those of their unit and organization. 4. Determine how many formal meetings are needed between the subordinate and the supervisor to discuss performance issues. Provide your rationale. Answer: Performance management systems can include six formal meetings between the subordinate and the supervisor: †¢System inauguration—The first meeting, system inauguration, includes a discussion of how the system works and the identification of the requirements and responsibilities resting primarily on the employee and on the supervisor. This discussion includes the role of self- appraisal and the dates when the employee and supervisor will meet formally to discuss performance issues. This meeting is particularly important for new employees, who should be introduced to the performance management system as soon as they become members of the organization. †¢Self-appraisal—The second meeting, the self-appraisal, involves the employee’s assessment of herself. This meeting is informational in nature and, at this point, the supervisor does not pass judgment on how the employee regards her own performance. This meeting provides an opportunity for the employee to describe how she sees her own performance during the review period. It is helpful if the employee is given the same form to be filled out later by the supervisor so that she can provide self-ratings using the same dimensions that will be used by the supervisor. †¢Classical performance review —The third meeting, the classical performance review meeting, during which employee performance is discussed, includes both the perspective of the supervisor and that of the employee. Most performance management systems include this type of meeting only. No other formal meetings to discuss performance are usually scheduled. This meeting is mainly past oriented and typically does not focus on what performance should look like in the future. †¢Merit/salary review—The fourth meeting, the merit/salary review, discusses what, if any, compensation changes will result from the period’s performance. It is useful to separate the discussion of rewards from the discussion of performance so that the employee can focus on performance first and then on rewards. If these meetings are not separated, employees may not be very attentive during the discussion of performance and are likely to feel it is merely the price they must pay to move on to the part of the meeting that really matters: the discussion about rewards. Although these meetings are separate, supervisors should explain clearly the link between the employee’s performance, discussed in detail in a previous meeting, and the rewards given. Rewards are not likely to carry their true weight if they are not linked directly to performance. †¢Development plan—The fifth meeting, the development plan, discusses the employee’s developmental needs and what steps will be taken so that performance will be improved during the following period. This meeting also includes information about what types of resources will be provided to the employee to facilitate the development of any required new skills. †¢Objective setting—The sixth and final meeting, objective setting, includes setting goals, both behavioral and result oriented, regarding the following review period. At this point, the employee has received very clear feedback about her performance during the past review period, knows what rewards will be allocated (if any), understands developmental needs and goals, and knows about resources available to help in the process of acquiring any required skills. 5. Give two advantages and disadvantages of using supervisors, peers, subordinates, self, and customers as sources of performance information. Then determine who will provide performance input for the job you are working with. Answer: Supervisors An advantage of using supervisors as a source of performance information is that they are usually in the best position to evaluate performance in relation to strategic organizational goals. Also, supervisors are often those making decisions about rewards associated with performance evaluation. Supervisors are able to differentiate among various performance dimensions (e. g. , adaptability, coaching, and development) regardless of the level of experience of the employee being rated. Peers Change management is extremely important to the successful implementation of this consolidation. The company is therefore revising how it assesses the competency â€Å"teamwork† at the senior and middle management levels, with the belief that successful teamwork is crucial to change management initiatives. One-third of the score for this competency is determined by ratings provided by peers. Subordinates Subordinates are in a good position to evaluate leadership competencies, including delegation, organization, and communication. Subordinates may be asked to rate their manager’s ability to (1) remove barriers that employees face, (2) shield employees from politics, and (3) raise employees’ competence. With this type of system, subordinates may hesitate to provide upward feedback if put on the spot. Self Self-appraisals are an important component of any performance management system. When employees are given the opportunity to participate in the performance management process, their acceptance of the resulting decision is likely to increase, and their defensiveness during the appraisal interview is likely to decrease. An additional advantage associated with self-appraisals is that the employee is in a good position to keep track of activities during the review period, whereas a supervisor may have to keep track of the performance of several employees. Customers Performance information provided by customers is particularly useful for jobs that require a high degree of interaction with the public or with particular job-related individuals (e. g. , purchasing managers, suppliers, sales representatives). Performance information can be collected from internal customers. Although the clients served may not have full knowledge of the organization’s strategic direction, they can provide useful information. In this training specialist review form I think the supervisors, peers and self will provide performance input for the job. 6. Using your appraisal form, describe briefly the psychological mechanisms leading to the inflation and deflation of performance ratings. Answer: There are motivational barriers that prevent raters from providing accurate performance information. Raters may be motivated to distort performance information and provide inflated or deflated ratings. In fact, supervisors may not even be trying to measure performance accurately and may attempt to use performance ratings for other goals. For example, a supervisor may be motivated to provide inflated ratings to

Investment casting Essay Example

Investment casting Essay Investment casting or lost wax casting has been used by many different cultures for thousands of years.The Egyptians used investment casting to make bronze statues and the Chinese made vessels and a variety of other items by using investment casting.Therefore, it is by no means a new process.The most modern approach, which has been used since the middle of the twentieth century is called ceramic shell casting.Because this is the most modern form of investment casting, I will bee focusing on this particular process for the entirety of the paper. The two different types of patterns used in investment casting are called expendable and permanent.Expendable patters are made of wax, are joint less, and yield a casting with a higher degree of accuracy than the permanent pattern method.The permanent pattern method uses a pattern that is made of wood, steel, or some other type of solid material.Using the permanent pattern method is usually cheaper than the expendable pattern method.One disad vantage of the permanent pattern method is that the molds must be assembled in separate parts, which makes it less accurate than the expendable pattern method. Thefirst step in investment casting when using the expendable pattern method is to manufacture a die.The die is made from strong alloys such as steel and Duralumin or softer fusible alloys where accuracy is less important.Steel dies are the best for long production runs and are machined from a solid piece of steel.Many dies are produced in two or more sections enabling the pattern to be removed once it is cast.After the die is done being machined it is coated with a parting agent or lubricant which helps the pattern to be extracted.The die is used repeatedly to makewax patterns for the investment process. Wax is the most common material used in investment casting.The wax has a low ash content, is compounded from natural and synthetic waxes and resins, and usua

Biography of Dorothy Vaughan, Groundbreaking NASA Mathematician

Biography of Dorothy Vaughan, Groundbreaking NASA Mathematician Dorothy Vaughan (September 20, 1910 – November 10, 2008) was an African American mathematician and computer. In her time working for NASA, she became the first African American woman to hold a supervisory position and helped the institution transition to computer programming. Fast Facts: Dorothy Vaughan Full Name: Dorothy Johnson VaughanOccupation: Mathematician and computer programmerBorn: September 20, 1910 in  Kansas City, MissouriDied: November 10, 2008 in Hampton,  VirginiaParents: Leonard and Annie JohnsonSpouse: Howard Vaughan (m. 1932); they had six childrenEducation: Wilberforce University, B.A. in mathematics Early Life Dorothy Vaughan was born in Kansas City, Missouri, the daughter of Leonard and Annie Johnson. The Johnson family soon moved to Morgantown, West Virginia, where they stayed throughout Dorothy’s childhood. She quickly proved to be a talented student, graduating early from high school at the age of 15 as her graduating class’ valedictorian. At Wilberforce University, a historically black college in Ohio, Vaughan studied mathematics. Her tuition was covered by a full-ride scholarship from the West Virginia Conference of the A.M.E. Sunday School Convention. She graduated with her bachelor’s degree in 1929, only 19 years old, cum laude. Three years later, she married Howard Vaughan, and the couple moved to Virginia, where they initially lived with Howard’s wealthy and well-respected family. From Teacher to Computer Although Vaughan was encouraged by her professors at Wilberforce to go to graduate school at Howard University, she declined, instead taking a job at Robert Russa Moton High School in Farmville, Virginia, so that she could help support her family during the Great Depression. During this time, she and her husband Howard had six children: two daughters and four sons. Her position and education placed her as an admired leader in her community. Dorothy Vaughan taught high school for 14 years during the era of racially segregated education. In 1943, during World War II, she took a job at the National Advisory Committee for Aeronautics (NACA, the predecessor to NASA) as a computer. NACA and the rest of the federal agencies had technically desegregated in 1941 by executive order of President Franklin D. Roosevelt. Vaughan was assigned to the West Area Computing group at Langley Research Center in Hampton, Virginia. Despite women of color being recruited actively, they were still segregated into groups separate from their white counterparts.   Nasa.gov The computing group consisted of expert female mathematicians who dealt with complex mathematical calculations, nearly all done by hand. During the war, their work was connected to the war effort, since the government firmly believed that the war would be won on the strength of air forces. The scope of activity at NACA expanded considerably after WWII ended and the space program began in earnest. For the most part, their work involved reading data, analyzing it, and plotting it for use by the scientists and engineers. Although the women- both white and black- often held degrees similar to (or even more advanced than) the men who worked at NASA, they were only hired for lower positions and pay. Women could not be hired as engineers. Supervisor and Innovator In 1949, Dorothy Vaughan was assigned to supervise the West Area Computers, but not in an official supervisory role. Instead, she was given the role as acting head of the group (after their previous supervisor, a white woman, died). This meant the job didn’t come with the expected title and pay bump. It took several years and advocating for herself before she was finally given the role of supervisor in an official capacity and the benefits that came with it. Vaughan did not just advocate for herself, but also worked hard to advocate for more opportunities for women. Her intention was not just to help her West Computing colleagues, but women across the organization, including white women. Eventually, her expertise came to be highly valued by the engineers at NASA, who relied heavily on her recommendations to match projects with the computers whose skills aligned best. In 1958, NACA became NASA and segregated facilities were completely and finally abolished. Vaughan worked in the Numerical Techniques division and, in 1961, shifted her focus to the new frontier of electronic computing. She figured out, earlier than many others, that electronic computers were going to be the future, so she set out to make sure she- and the women in her group- were prepared. During her time at NASA, Vaughan also contributed directly to projects on the space program with her work on the Scout Launch Vehicle Program, a particular type of rocket designed to launch small satellites into orbit around the Earth. Vaughan taught herself the programming language FORTRAN that was used for early computing, and from there, she taught it to many of her colleagues so they would be prepared for the inevitable transition away from manual computing and towards electronics. Eventually, she and several of her West Area Computing colleagues joined the newly formed Analysis and Computation Division, a race- and gender-integrated group working to expand the horizons of electronic computing. Although she tried to receive another management position, she was never granted one again. Photographs from Dorothy Vaughans retirement party. Vaughan retired from NASA in 1971.   Courtesy Vaughan Family /  Nasa.gov Later Life and Legacy Dorothy Vaughan worked at Langley for 28 years while raising six children (one of whom followed in her footsteps and worked at NASA’s Langley facility). In 1971, Vaughan finally retired at the age of 71. She continued to be active in her community and her church throughout retirement, but lived a fairly quiet life. Vaughan died on November 10, 2008 at the age of 98, less than a week after the election of America’s first black president, Barack Obama. Vaughan’s story came to public attention in 2016, when Margot Lee Shetterly published her nonfiction book Hidden Figures: The American Dream and the Untold Story of the Black Women Who Helped Win the Space Race. The book was made into a popular feature film, Hidden Figures, which was nominated for Best Picture at the 2017 Academy Awards and won the 2017 Screen Actors Guild Award for best ensemble (the guild’s equivalent of a best picture award). Vaughan is one of the three main characters in the film, along with colleagues Katherine Johnson and Mary Jackson. She’s portrayed by Oscar-winning actress Octavia Spencer. Sources Dorothy Vaughan.

Environmental engineering report- flocculation Assignment

Environmental engineering report- flocculation - Assignment Example Proper designing, construction, and minimizing mechanisms are essential for protecting the environment and thus, the process of flocculation is regarded as a significant environment engineering techniques that helps to provide purified water. Thus, the report postulates that the flocculation technology is one of the superior environmental engineering processes to reduce the perilous and harmful substances that are generally present in the water, but the chance of errors remain in the process due to utilization ineffective chemicals. Environmental engineering is the application of science and engineering technology in order to respond to the challenges imposed to the environment. Besides, with the growing population, the extensive land-uses, modernization of technology, increasing operational activities and other factors has led to a significant threat to the environment. However, through this growing concern various environmental engineers are engaged in the activities to develop and provide most noteworthy and technical solutions in order to effectively deal and resolve the environmental problem and issues through the optimum utilization of necessary resources. The main object of the environmental engineering is to improve the condition of the natural environment through providing healthy air, water and land supporting the human habitation as well as a prospering ecosystem. In this regards the flocculation is an indigenous engineering mechanism to treat the wastewater. This mechanism is used to neutralize as w ell as aggregate the various ‘colloidal particles’ that are present in the water. Moreover, this mechanism is utilized to reduce the hazardous substances, color, phosphorous, organic substances, and metal traces including iron, chromium and manganese present in the water. Moreover, due the significant characteristics of colloidal suspension present in the water, it is difficult to separate through the conventional

Introduction of the new Nokia Lumia Product Essay

Introduction of the new Nokia Lumia Product - Essay Example product development is crucial to survive in the global competitive environment especially when it comes to technology such as gadgets, mobile phones, tabs and other electronic devices. In the era of globalisation it becomes crucial for organisation to innovate new product to keep up with the competition in the global environment and secure a better market place. Timely and responsive new products have become more critical in the global environment and there arise the need to response quickly to the changing dynamics of global forces (Yelkur & Herbig, 1996, p. 38). Methodology Research methodology includes two forms of research, primary research and secondary research. Primary researches are conducted based on questionnaires, interviews and can be both qualitative analysis and quantitative analysis. Secondary research is based on data which were already found and an analysis is made on the existing data. The methodology used to analyse the product introduced by Nokia, Nokia Lumia 820 and 920 in collaboration with Microsoft operating system are done mainly through secondary research. Data are collected from sources such as web, books, news and other relevant sources and are further analysed. Analysis and findings of Nokia and Microsoft are also based on SWOT analysis. Findings and Analysis According to IDC press release the global mobile phone market grew by 1% in the second quarter of 2012 where Apple and Samsung shipped half of the global Smartphone. With respect to the Operating System, Android has expanded its dominance in the global Smartphone market and accounted for 68% of the total Smartphone shipped in second quarter in 2012. According to findings, success of Android can be traced to Samsung accounting for 44%, iOS posted growth with double digit and remains at... This essay stresses that Nokia currently has been suffering from a major decline in market share leading to major loss for the company. Symbia which was the OS for Nokia did not help the company to generate enough revenue and as a result the company has partnered with Microsoft regarded as an opportunity for the company to increase its market share and profits. Nokia was facing a tough challenge from OS like Android, iOS due to the lack of innovation made by Nokia and also its slow response to match up the international market demands. Thus the advantage of pairing Nokia with Microsoft will be beneficial for both as within six months of the launch of Lumia Nokia from zero percentage went up to a third of the overall windows phone devices in the US. Nokia which was once the market leader in the mobile category had recently suffered a setback in the smart phone category and is trying to catch up with Apple and Samsung. This paper makes a conclusion that the management decision to partner with Microsoft has resulted to be beneficial for Nokia as the growth rate has increased within the six months of its launch of Nokia Lumia 820 and 920. In the competitive mobile Smartphone market, Nokia was lagging behind the market leaders Samsung and Apple and had suffered huge loss. Now entering into partnership with Microsoft it hope to regain back its lost market share and introduce new range of products with exciting features.
