A Task on Geotechnics - Coursework Example Since in our case and , point L has such Figure 1. coordinates . At the same time, x coordinate of point M equals , while its z coordinate equals . Since in our case , , , and , point M has such coordinates . Points L and M are shown on Figure 1. We look for equation of the dam slope adjacent to the water reservoir in the form where and are constants. Since points L and M lie on this line, and can be found from the solution of the following system of equations (1) Solving the first equation of this system for we obtain the following . (2) Substituting the right hand side of equation (2) for in the second equation of system (1) we obtain the following . Therefore, . From equation (2) it follows that . Hence, the equation of the slope adjacent to the water reservoir has the following form:. The water level is equal to . Since and , the z coordinate of point A equals 43. Moreover, point A lies on line LM. Therefore, its x coordinate satisfies the following equation . Solving it for x we obtain that point A has such coordinates . In its turn, the difference between x coordinates of points L and A is the following:. Point F on the water surface at distance from point A has the following coordinates –. The difference between x coordinates of points F and O is the following: . ...

Therefore, we draw a curve that intersects line LM at right angle and â€Å"meets the base parabola smoothly and tangentially at a convenient point say,† N (Vijayendra, 2010, p. 15). The final shape of the free surface is shown on Figure 2. Figure 2 Problem # 3 Curve KNA shown on Figure 3 is a free water surface. Hence, the pore water pressure along this line is constant and equal to the atmospheric pressure (Vijayendra, 2010, p. 11). We assume that the pore water is incompressible. The hydraulic head is given by such the expression where here and below is the water density, is the acceleration of free fall, is pressure of the pore water (Wikipedia, n. d.). Therefore, the head loss between any two points belonging to this curve is proportional to the difference in their vertical coordinates. Since curve KNA is a phreatic line, it is a flow line (Vijayendra, 2010, p. 11). Segment LO shown on Figure 3 is the interface between the soil and the impermeable boundary. Therefore, it is a flow line (Vijayendra, 2010, p. 4). We draw the equipotential lines that start at points , , , and N making smooth transitions between their â€Å"straight and curved sections† (Vijayendra, 2010, p. 5). These lines are perpendicular to flow lines LO and KNA, as it is shown on Figure 3. Segment LA shown on Figure 3 is the â€Å"soil and permeable boundary† interface. Therefore, it is an equipotential line (Vijayendra, 2010, p. 4). The toe drain is a pipe

WALMART-international corporation Research Paper

WALMART-international corporation - Research Paper Example The company has worked very hard to get into this position by pursuing right strategies in both national and international regions. The organization thrives as an efficient merchandiser with effective processes and systems. These strategies have contributed to the overall buying power, superior growth and leadership in various systems such as logistics and supply chain. The company is headquartered at Bentonville, Arkansas, United States. The company has established more than eighty-five thousands stores across the globe. Product portfolio of the company includes, apparel, footwear specialty, supercenter, discount store, warehouse club, cash & carry, superstore, hypermarket and supermarket. The strategies of corporate management include selling products of high quality and high brand name and it lowest prices (David 293-298). The low prices are kept by reducing the overall operational costs through the use of advanced and unique electronic technology and unmatched warehousing. Mercha ndising deals are negotiated directly from the manufacturers which eliminate the work of middle men and save a lot of costs. The community outreach of Wal-Mart is focused on various goals such as involvement with local community services, customer satisfaction, providing scholarships for higher studies etc. The major emphasis of the company is on environmental and child issues. Mission and Goals Mission and goals are the building blocks of an organization. They guide the actions of an organization and define the goals and objectives. Whether an organization is big or small, to have a mission is the first step for setting up a business. The mission and purpose of Wal-Mart is to save the money of its customers so that they can have a better life. Apart from that, the purpose of the company is derived from the philosophy of the company’s founder. The motto of the retail giant is to work together and lower the living cost for everyone (Ahmed 23-30). This will provide an opportuni ty for the world in terms of saving money and enjoying a better life. Core Competencies Competitive advantage for Wal-Mart lies in its ability of cost differentiation and strong distribution channel across the globe. Cost leadership and distribution strategy of Wal-Mart has created barrier for competitors to copy the strategy of Wal-Mart (Gagnon 130-135).Expanded distribution channel of the company has helped them to sell products to large base of customers and increase market saturation for competitors. Wal-Mart follows a low cost leadership strategy. Macroscopic view of Wal-Mart’s competitive strategy shows that the company uses a resource based model in order to develop a value chain proposition which can’t be matched by competitors. With the help of the resource based view (RBV) model, it can be summarized that Wal-Mart has three major resources which are tangible, intangible and human resources, in order to create and maintain strategic capabilities. Resource capa bilities of Wal-Mart can be explained in the following manner. Access to both tangible and intangible resources has helped Wal-Mart to achieve the capabilities which has established the departmental chain as a global market leader.
