...only electrical energy. We know that energy can’t be produced. It can only be transformed form one kind to another. The cheapest and the most available source of energy is the sun. We can use the solar radiation, which is transformed in to electrical energy directly using PV cells. Now, to solve the electric energy crisis, we need to do a few things. * Increase the production * Decrease use, specially misuses * Reduce dependency on bio energy We will try to work on all the solutions altogether to solve the energy crisis in our project. The main idea of the project is consumers of electricity will turn into the producers of electricity. Every house will turn into a mini power plant using PV panel. It will produce electricity for that house, and whatever will be left after using in the house will be supplied in the national power grid. Government will pay the owner of the house, as well as the owner of that Mini Power Plant. The power meter will run in the opposite direction, and the producers will get cash payment from the government. Where to work: * We can make the model more effective. * The way of supplying the electricity to the national grid. * We can work on making the system...

This interest stems from several factors such as improvement in living standards, reduced capital cost, stricter environmental constraints, and national programs that encourage renewable energy systems. To promote the usefulness of such renewable energy systems, a simple design and cost analysis method was developed. Its purpose is system sizing and life cycle cost analysis. Key parameters such as energy consumption, storage requirements, solar resources and financing options are entered into the program. Results such as system size and project cost are computed. For the financial analysis, Internal Rate of Return and Payback Period are used as project evaluation techniques. The method was tested for four PV systems with different geographical conditions and energy consumption profiles. Results show that the PV systems can be attractive on economic basis if governments provide sufficient funding and incentives. 1. INTRODUCTION Photovoltaics offer consumers the ability to generate electricity in a clean, quiet and reliable way. Because the source of energy is usually the sun, the electricity produced by PV systems is an...

One hundred million people shop at Wal-Mart every week. Wal-Mart is very convenient for people to shop at. Most people do not even have to shop at other stores because Wal-Mart has everything. It’s also convenient because it is right around the corner from a lot of customers houses; they don’t have to travel far to find a Wal-Mart store so they save gas. People already know that Wal-Mart has the lowest prices so they don’t have to search for stores with low prices. The items sold are good quality as well as cheap. What more could someone ask for. Wal-Mart is a world leader in logistics and promotes greater efficiency between its suppliers.

...The systems approach Attempts to reconcile the classical approach (emphasised the technical requirements of the organisation and its needs) with the human relations approach (emphasised the psychological and social aspects, and the consideration of humans needs). The attention is focused on the total work organization and the interrelationship of structure and behavior, and the range of the variables within the organisation. The principal idea is that any part of an organisations activities affects all others parts. The business organisation is an open system, there is continual interaction with the broader external environment of which it is part. The systems approach views the organisation within its total environment and emphasies the importance of multiple channels of interaction. The systems approachs views the organisation as a whole and involves the study of the organisations in terms of the relationships between technical and social variables within the system. The contingency approach This approach explain that the most appropriate structure and system pf management is therefore dependent upon the contingencies of the situation for each particular organisation, this approach implies that the organisation theory shouldn’t seek to suggest one best way to structure or manage organisation but should provide insights into the situational and contextual factors which influence management decisions. Other approaches to the study of organisations: -The decision-making...

...first lectures of the course show an empirical and theoretical view of the major principles of the organizational design as well as the alternative design forms. The stakeholders, both insiders and outsiders, and their behavior or relations of cooperation and competition suppose an analysis need that provides them of a huge importance. I also realize about the importance of the agency theory and the problems and remedies caused, improving the importance of efficient corporate governance. This need of a good organization is solved by the systems theory, ”Organizations are systems of interdependent activities linking shifting coalitions of participants; the systems are embedded in – dependent on continuing exchange with and constituted by – the environments in which they operate”. (Scott, 1998:28). The systems which formed the organization have a common target and are classified in three levels based on their relevance. Both, stakeholders and systems, needs an analysis in order to get success in our procedures and adapt the venture structure to the different organizational designs provided in the lectures. After understanding these concepts, the lectures focused on the relation between the main management factors (Vision and mission) and the drivers analyzed, providing goals and strategies to the organization. As important as the creative process is the analysis to know the organizational boundaries, which let the organization look for available goals based on the efficiency and effectiveness...

...Organizations as a system. A system is a whole made up of parts. Each part can affect the way other parts work and the way all parts work together will determine how well the system works. when can look at business organization as a system because it conforms to the system definition; it recognizes the interrelationships of people, processes, decisions and designs organizational structure in order to realize its projected economic goal. An organization with a good designed system will requires an understanding of how all the parts (for instance, HR department, production department, logistic department, finance department, sales department, marketing department, IT department …etc) fit together as a whole, an intimate understanding of the parts themselves for a better understanding of endogenous event and a full awareness of the organization’s environment including the other external systems to which it is connected to better prepare for exogenous changes. Some hypothetical problems that disrupt the balance of the an organization would be a coordination or communication issue between departments, for instance HR department not selecting adequate candidate for a specific job skill because it did not have all relevant information about the job, or for instance marketing department lunches a new product without integrating logistic department in the project which may cause delays of production and order fulfillment issues. Another issue that may disrupt the balance of the system is exogenous...

...PubMed Abstract: Retroviral capsid proteins are conserved structurally but assemble into different morphologies. The mature human immunodeficiency virus-1 (HIV-1) capsid is best described by a 'fullerene cone' model, in which hexamers of the capsid protein are linked to form a hexagonal surface lattice that is closed by incorporating 12 capsid-protein pentamers. HIV-1 capsid protein contains an amino-terminal domain (NTD) comprising seven α-helices and a β-hairpin, a carboxy-terminal domain (CTD) comprising four α-helices, and a flexible linker with a 310-helix connecting the two structural domains. Structures of the capsid-protein assembly units have been determined by X-ray crystallography; however, structural information regarding the assembled capsid and the contacts between the assembly units is incomplete. Here we report the cryo-electron microscopy structure of a tubular HIV-1 capsid-protein assembly at 8 Å resolution and the three-dimensional structure of a native HIV-1 core by cryo-electron tomography. The structure of the tubular assembly shows, at the three-fold interface, a three-helix bundle with critical hydrophobic interactions. Mutagenesis studies confirm that hydrophobic residues in the centre of the three-helix bundle are crucial for capsid assembly and stability, and for viral infectivity. The cryo-electron-microscopy structures enable modelling by large-scale molecular dynamics simulation, resulting in all-atom models for the hexamer-of-hexamer and pentamer-of-hexamer...

...1. From the Portman Hotel case study, there were many fundamental attribution errors made by groups or type of people. A few of them are • Firing PVs in the first month by the Management due to their low turnover (16%) • PVs complaint about porters, who were slow to respond to their requests to carry guest bags to and from the room • Supervisors complaint about floaters being responsible for team lost loyalty. • PVs blaming on Scott for continual lack of organization and for his poor planning. etc In all the above examples, the blame is on different groups of people or on the management instead of the structure of the Portman Hotel System, which is the 5-star team plan. The Management thought it was PV’s fault for low turnover and fired some PV’s. Even in the extreme condition, let us assume that some PV’s neither worked nor followed Hotel Mission of being showing high level of ultimate service to customers. Even in that case, the question would be what caused the Management to hire such person? This would lead defect in the system that allowed the wrong person to be hired. So in either of the case, the individuals are blamed rather than the system, leading to fundamental attribution error. If this error had not been made, then the results would have been different in many ways and the reason for such results is as it would create a strong bond between employees and Management as a single family of Portman Hotel. • Firstly, the PV’s...

Detailed review of literature was carried out to cover the following study areas as shown: - Organizations - Management - Motivation (Reward) and its theories - Relevance of motivation (reward) on productivity. 2.2 ORGANIZATION Organization can be defined as two or more people who work together in structured way achieve a specific goal or goals. Organization can be defined form diverse perspectives. According to Scott (1981) these are there perspective for defining organization these are: 1. Organization as rational systems. 2. Organization as natural systems. 3. Organizations an open system. Organization as Rational Systems: The definition of Organizations as a rational system emphasizes two major characteristic of Organizations. a. Specification of goals b. Formalization of structure.

...Nakelya Moragne 03-18-2014 HRDV 5630 QE S2 2.) How does OD differ from a single-change technique such as management training? Answer: OD represents a systems approach that is concerned with the interrelationship of various divisions, departments, groups, and individuals as interdependent subsystems of the total organization. A single technique such as management training is aimed at changing individual behavior, whereas OD is focused on the larger goal of developing an organization-wide improvement in managerial style. OD uses many different techniques and no single technique represents the OD discipline. 5.) Explain three basic responses an individual may have to socialization. Socialization is the process that adapts employees to the organization’s culture. An individual may respond to the socialization in three basic ways. The notion of socialization has been primarily a result of the inequality that exist within the capital system, as a result of the relationship present between the capitalist and the workers strata of the society. Though the response of capitalism to socialization has traditionally been harsh claiming it to be against the right of ownership for which the capitalist system stands for, the response have been changing in its magnitude from time to time. In today’s world where we are witnessing such acute difference in the wealth distribution in different parts of the world. Individuals may be worried about how they’re going to interact with their...
