this paper introduces a mesh generating algorithm for solving the traffic flow equation as a conservation law equation. the idea behind the new method is to use the characteristic curves and moving non-oscillatory finite volume method. in addition, when characteristic curves intersect, the proposed scheme uses shock speed equation in order to improve computational efficiency. we also compare...

The profitability of a firm is jointly determined by the market structure and the firm’s organizational structure. To explore the relationship between these two structures, a real-time information processing model in a dynamic duopoly environment is developed, which allows us to examine the effects of the product market competition and the cost of delay. It is found that Decentralization tends ...

Mrs. Umbridge walks through the hall of Hogwarts with a certain air about her; each of the students knows that what she says will be the !nal decision (Barron, 2007). The O.W.L.S. will be the deciding factor on how well the students do in the future and any student who does not meet the standards will not be able to partake in any form of witchcraft in the future. Students are taught a basic kn...

Cloud computing can be defined as the provision of computing resources on-demand over the Internet. Although this might bring a number of advantages to end-users in terms of accessibility and elasticity of costs, problems arise concerning the collection of personal information in the Cloud and the legitimate exploitation thereof. To the extent that most of the content and software application a...

We analyze a model of moral hazard in local public services, which could be efficiently managed by officials under democratic accountability, but not who are appointed the ruler centralized autocracy. The might prefer to retain an official diverted resources from services contributed part benefit ruler. autocratic would value better only when residents reduce taxable investments, become unprofi...

congenital radial club hand is an intercalary or terminal deficiency characterized by radial deviation of the hand, marked shortening of the forearm, and generalized underdevelopment of the extremity. we performed centralization of the ulna in 12 forearms of 10 patients with severe congenital radial club hands. the mean follow up was 42 months after operation (24 to 68 months). the mean age at ...
