in this paper, a new identification of the lagrange multipliers by means of the sumudu transform, is employed to  btain a quick and accurate solution to the fractional black-scholes equation with the initial condition for a european option pricing problem. undoubtedly this model is the most well known model for pricing financial derivatives. the fractional derivatives is described in caputo sen...

putin’s policies have had significant impact on russian foreign policy after the cold war. despite the fact that putin sought for increasing russia’s power to the same level as the cold war, however; he was aware that the nature of the international system has undergone serious changes. therefore, some specific factors including close collaboration with the united states, an energy-oriented for...

implementing information technology projects requires a calculated process to prevent failure. at the same time application of information technology in organizations faces various potential risks. exploring information technology environment in organizations reveals the potential risks and provides a structure for comprehensive risk management. there are various methods available for risk mana...

Conventional energy sources are fast depleting due to poor conservation practises and excessive usage while the world’s energy demands are growing by minute. Additionally, the cost of producing conventional energy is rising also leading to an increase in harmful environmental pollution. Hence, there is a need to look at alternative energy sources such as sun, water and wind. Photovoltaic (PV) i...

Current mode (ECL) logic has long been the option of choice in those applications requiring logic functions at multigigahertz rates. This trend continues despite the obvious very high static power consumption and small signal swing characterizing this logic. In this work we investigate a simple mechanism for LowVoltage-Swing Logic (LVSL) to greatly reduce the power requirement of a CML logic su...

Renewable energy sources i.e., energy generated from solar, wind, biomass, hydro power, geothermal and ocean resources are considered as a technological option for generating clean energy. This paper presents the Solar-Wind hybrid Power system that harnesses the renewable energies in Sun and Wind to generate electricity. System control relies mainly on micro controller. It ensures the optimum u...

The recent development of high power DC/DC converters (more commonly know as Chopper Rectifiers) allows customers the option to keep older rectifier transformers and refurbished systems if reconfiguring or installing new cell line loads. Normally, new cell line impedances would require the replacement of transformer/rectifier equipment. This paper is intended to describe how one can change the ...

Carbon emission right allowance is a double-edged sword, one edge to reduce as its original design intention, another has in practice slain many less developed coal-consuming enterprises, especially for those thermal power industry. Partially governed on the hilt hands of authority, body this sword prices carbon right. How should plants dance blade motivates research. Considering impact price f...
