prepare and submit a term paper on Introductory Control: First Order System Response.

/in /by

As the value of alpha escalates the system responds relatively quickly as depicted by the underlying lowest rise in the table above.

The underlying step response depicts that the output of the system commences reaching the final value succeeding the first-order system response, which essentially exponential increase of the output. The speed of the system depends on the value of the alpha that it α it dictates whether a system will be either faster or slower. Moreover, a relatively higher value of α normally results in a faster response.

This can be verified by the three graphs below that the steady-state value of every response. For the relative value of alpha, the underlying steady values translate to the lower as the prevailing alpha appears at the denominator. Thus, the alpha value of eight possesses steady-state value of 0.125, which is the lowest.

The transfer function is significant for the analysis of the system stability. A system is stable in case e poles of the underlying transfer function possess negative real parts. This implies that the quantities of s at the existing denominator become zero. When the poles are on the complex s-plane that is all the poles are within the left half of the plane then it is under stable operation. The system marginally stable when two poles on the imaginary axis and the corresponding system have oscillation. The system is stable since the pole’s real part is negative. Moreover, the system’s stability is attained from the state-space model. Transfer function poles are the system matrix A’s eigenvalues.

To make the system stable, the alpha value ought to be that the underlying poles stay left side of the S-plane, which depicts that the α&gt.0. When the value of α=0, the system is stable and called marginal stable

Because the prevailing negative value of the alpha makes the underlying exponential term positive, the corresponding output escalates exponentially.&nbsp.

The paper shows that one must observe the environment with a greater depth because his proposed structure will have an environmental impact at the end of the day and in order to reduce that impact he must study the surroundings. This includes the type of vegetation in the area, the animal that lives around and other structures that are close to the perspective construction site.

As a design engineer, I will find a location along the river banks where the land is comparatively clear and there are no trees. This will be a good location because no trees are to be cut, if there is no such site available choose the areas having least no trees and then it is suggested that if one tree falls down, at least 5 of such new should be planted in the near vicinity. Then before cutting the tree special care should be given to shifting the bird’s nest and other animals residing near the tree. Then comes the wood with which we are going to construct the bridge, in this what a responsible design engineer can do is that he can instruct the client to dictate the contractor to use the wood which is made from the wood of farmed trees.

Another environmental issue that will arise is the production of waste during the excavation process and then during the construction itself. A good designer would do two things about it, firstly he will design the components that are available readymade from the market and you just have to fix them together this will reduce the waste produced at the site. Secondly, it is the job of the design consultant to draft the contract document and in which he can make the contractor contractually bound to effectively manage the waste and a suitable dump site is selected after the consensus of both the parties. The site should be under a repetitive cycle of clearance and cleaning. Furthermore, as a design engineer, I can use the ready-mix concrete for the construction of abutment to safeguard the environment. this is proposed to avoid the batching of concrete on site which will result&nbsp.in extra waste and dust.

write an article on clean water for farm to use Paper must be at least 3000 words.

Farm water comes from a number of different sources and therefore its quality varies from one source to another. Water sources include dams, boreholes, wells, rivers, and town water channels, and recycled water. Water from various sources may be of unsuitable quality for its intended purposes such as irrigation, stock, household, or other farm activities. It is important that the correct water quality problems that affect the usage of the farm as well as the productivity of crops are identified. Water quality can have adverse effects on plants growing on the farm, soils, livestock present in the farm, irrigation equipment operational in the farm, water for domestic usage, and the general farm activities.

This describes the acidity or alkalinity of water. The PH of the soil can affect the growth of plants, irrigation equipment, pesticide efficiency, and the quality of drinking water. Water that has a PH that is below 7 is acidic and that which has a scale above 7.5 is alkaline in nature. Most of the natural waters that exist are between PH 5 and 8. The accepted PH for farm water is 6.5-7.5.

The iron bacteria will develop in the water where the concentration range of iron is 0.3 to 1.5 mg/l. concentrations that are above 1.5 mg/l tend to favor the development of iron deposits. The irrigation systems that are used for fertigation should use water that has high iron content.

This refers to the measure of the number of exchangeable sodium cations in water or in soil. In water, it is expressed as a sodium absorption ratio(SAR). If the SAR is greater than 3, the water is sodic and is a potential hazard in soils.

It is important to consider water processing system design in the development of an efficient water treatment system. The treatment system must be designed with a number of fundamental water treatment processes. These processes include coagulation, sedimentation, PH measurement, and filtration process.

The global economy is heavily dependent on oil production and this source of energy controls over 90% of the world economy and about 25% of the Gross domestic product of the oil-producing countries [1].

Oil and gas are produced both onshore and offshore and it is transported through pipelines to the refineries and various depots. The global oil reserve is estimated at about 3520 billion barrels and an average daily production of 2500-3000 billion barrels. Over the past years, the global production of oil and natural gas has increased substantially [2]. This has resulted in increased processing and transportation of oil between points. There has been a great increase in the oil spills and theft of oil resulting in environmental pollution and degradation [3]. Oil spills normally result from a number of factors including defective materials, corrosion of pipes, ground erosion, tectonic movement on the offshore wells, and vandalism of the oil and gas facilities [1]. Oil spills normally result in adversely fatal impacts such as environmental degradation, fires, and massive loss of property.

Taking a more specific focus on Nigeria, the country heavily depends on oil production to support its economy and its GDP. Various multinational companies in the country have invested in oil and gas production and even though this sector is doing fairly well, oil spills and theft remain a big problem in the country [2]. Most of the oil spillage in Nigeria is associated with equipment failure and corrosion of pipes as a result of aging. Vandalism contributes about 69% of the total spillage while 20% is contributed by controlled incidents [1]. The table below shows the recorded spillage for a period of 10 years.

In order to maximize profits, companies use various tools for product management such as the Boston Matrix Tool and product lifecycle management [4]. Use of information technology comes in handy in the long term planning, management and marketing of the products.

prepare and submit a paper on american romanticism in the landscape paintings.

/in /by

Cole’s “The Oxbow” belongs to the American Romantic Movement. In the 19th-century New World, romanticism in the field of visual art was widely viewed in terms of two main subjects: nature and man (Strickland, 2007). In particular, nature and landscape were utterly synonymous. Cole’s painting evidently depicts a picturesque image seen in the Connecticut River in the time of the romantic artist. The masterpiece clearly shows trees, shrubs, waters, and other images visible in the natural landscape. Further, the landscape painting is portrayed like a picture-postcard perfect, a characteristic of American romanticism.

Church’s “The Heart of Andes” also belongs to the 19th-century American romanticism. Similar to Cole’s painting. Church’s artwork depicts the panoramic view of the wilderness. “The Heart of Andes” shows the exotic of nature. In contrast to the cityscape, Church’s painting evokes the untamed and virgin element found in the vast green forest. American romanticism is basically defined in terms of landscape, seascape, and other natural wonders — what Kaufman and Macpherson (2005) call sublime and beautiful.

The landscape paintings prominent in the 19th-century America are considered as part and parcel of the American romanticism. Cole’s “The Oxbow” and Church’s “The Heart of Andes” are beautiful and sublime landscape artworks characterized in a romantic movement. Both paintings exhibit nature in its grandeur and exotic nature.

prepare and submit a paper on how sucessful has the government and the bank of england been in running the british economy over the past 2 years.

Bank of England and the British Economy October 2008 The fifth largest Economy in the world is the Economy of the United Kingdom also known as theBritish Economy and this is on the basis of the market exchange rates. in terms of purchasing power parity it is sixth largest in the world. In Europe it is the second largest Economy, second only to Germany’s Economy. There are three countries which make up the British Economy namely, England, Wales, Northern Ireland and Scotland. This paper will throe light upon how successful the government and the Bank of England have been in running the British economy over the past two years.

The major Economies of the world are facing a credit crunch and this has also affected the British Economy in more ways than one. Obtaining credit has become one of the most difficult tasks and in addition to this. the cost of mortgages has also adversely affected the major Economies of the world. “A significant level of short-term debt—unsecured or secured against property, as well as credit cards—is widespread. Over the last ten years the economy under the Labor government has grown in large part because of consumer spending financed by debt. (The Impact, 1 October 2008). According to a report it was found that out of 47.5 million adults in UK, 4.8 million people were found to be spending more than what they earned. It is predicted that in the near future the British Economy is going to be affected by the credit crunch, just like the economy of United States of America.

The British economy is facing two major problems as of now namely, the GDP (Gross Domestic Product) growth is really slow and the rising rate of Inflation has taken on a toll on the British Economy. The bank of England is trying everything possible to stimulate the economic growth in the British Economy. the cut in the interest rates proves the same. Currently the British Economy can take a little satisfaction from the fact that the employment rate has risen and there is less unemployment found in Britain than what it used to be earlier. ““The employment rate for people of working age was 74.5 per cent for the three months to October 2007, up 0.1 from the previous quarter but unchanged over the year. The number of people in employment for the three months to October 2007 was 29.29 million, up 114,000 over the quarter and up 226,000 over the year. Total hours worked per week were 940.0 million, up 5.1 million over the quarter and up 11.7 million over the year. These figures for people in employment and hours worked are the highest since comparable records began in 1971,” (British Economy, 1 October 2008).

(British Economic Condition, 1 October 2008)

The above chart shows that the gain that the British economy witnessed in the year 2007 has not been repeated in the 1st quarter of the year 2008. The economy witnessed no gain in the second quarter of the year 2008. The British economy is being affected by various reasons. some of the most important are the credit crunch in the various economies of different countries, the inflation rate has gone up because of the rise in oil prices and there are numerous other reasons for the same. Big Banks in England like Northern Rock are facing a really tough time in keeping up with the demands of the customers. Banks are cancelling the credit cards of the customers, so all these events show that all is not well in the British Economy and the government and the Bank of England have to do something about this before its too late.

Companies do this by installing monitoring tools on the mobile phones of the employees (EY, 2014). However, the article warns organizations that they should ensure that the monitoring tools safeguard only essential information to avoid interfering with the private information of workers.

The next trend is the use of data analytics to conceal the information that companies get from consumers on social media. This is because social media users provide organizations with too much private information, and this means that such data needs to be safeguarded (EY, 2014). Therefore, the use of data analytics will protect the information from social media users. for example, the data may be stored in encrypted forms to ensure that unauthorized persons are not able to read and understand its meaning.

The last technique of privacy discussed in the article is the use of cloud service brokerage. The article, however, argues that companies need to analyze the use of this service to ensure that it does not threaten the privacy of information.

Founded in the year 2004, Mandiant is regarded as one of the leading cybersecurity companies engaged in investing various types of computer security breaches across the organizations located in different parts of the world. Since its inception, the cybersecurity firm is committed to providing vital support by safeguarding each system-related information and data, and it helps organizations to carry out an evidence-based investigation process to perceive appropriate results about any type of security breaches in the organizations. According to a brief understanding of the current operational process, the cybersecurity mechanism of Mandiant includes safeguarding confidential product plans, and theft of vendor and client contract-related information, along with a customer database and financial assets of the organizations irrespective of dissimilar commercial fields. In addition, the cybersecurity structure of Mandiant also deals with organizational secrets and is responsible to protect them from uncertain security breach related issues (Mandiant, A FireEye Company, 2015).

Although Mandiant garnered its strong position through protecting the commercial credentials of the global organizations, the company has gained world recognition by its investigation of cybersecurity breach made by APT. According to the APT1 report of the organization, Mandiant has critically distinguished various APT&nbsp.groups along with their issues associated with the breaching cybersecurity of more than 141 US-based and globally renowned organizations. The APT1 in the Mandiant’s report referred APT groups in the cybersecurity-related issues. The APT1 report of the company is released with an aim of generating major awareness about the threat of cybersecurity breaching and the degree to which it can create security risks on the nations and the global economic condition as well (Rid, 2013).&nbsp.In addition, the report has also critically summarized the actual process along with tools, tactics, and procedures (TTP) that enabled APT1 to steal successfully the confidential information and intellectual property of different privately and publicly held foreign organizations.&nbsp.

prepare and submit a paper on effects of pollution of water.

/in /by

Over 80 % of marine water pollution comes from land-based actions such as oil, toxic chemicals, solid waste, sewage, and fertilizers. Oil leaks are a massive problem and cause significant harm to marine life in our water resources. Oil leaks are only responsible for 12 % of the oil that goes into the ocean every year. According to a study by the Nation Research Council of the United States, 36 % comes down from rivers as waste from cities and the industries (Marine problems: Pollution). Another cause of oil leaks is the discharge of freight residues from huge cargo ships. These huge cargo ships contaminate the ports, rivers, and oceans. Water pollution is also caused when rainwater washes off plowed fields to rivers, ponds, and oceans carrying fertilizers and waste. Moreover, these suspended materials are loaded with toxic materials that are contained in fertilizer materials such as phosphates and nitrates. With excess quantities of these nutrients, the marine vegetation and planktons have difficulties in growth. thus, food for underwater marine life becomes limited.

Another significant source of water contamination includes raw sewage that has harmful substances in it and cannot only harm marine life but can as well, harm human life. Raw sewage carries a risky quantity of infectious bacteria, harmful substances, and harmful viruses. Untreated sewage is supposed to be carried through wastewater pipes to treatment plants for processing. Although there are regulations to assist in securing the environment against raw sewage going into rivers, lakes, and oceans, most of these facilities are old, and the wastewater pipes are broken and worn-out from the overload of sewage. Owing to this issue, there is a direct release of raw sewer into lakes, rivers, and oceans. There are quite a number of other methods of releasing untreated sewage into the ocean.&nbsp.This release of raw sewage consists of overflows of sewage that usually occur when runoff water goes into damaged and corroded pipes.&nbsp.
