In her confirmation hearings, U.S. Secretary of State Hillary ClintonClinton, said, “AmericaAmerica cannot solve the most pressing problems on our own, and world them without AmericaAmerica…We must use what has been called ‘smart powerSmart power,’ full range tools at disposal.”

this paper deals with a failure investigation of boiler feed pump’s shaft of a steam power plant. boiler feed water pump is a specific type of pump used to pump, feed water into a steam boiler and is one of most important part of steam power plants. feed pumps failure may cause failure of another part of steam power station, therefore keep them safe is an important problem. there are 12 feed pu...

low level lasers, cold or soft lasers: these lasers do not produce thermal effects on tissues and induce photoreactions in cellsthrough light stimulation which is called photobiostimulation. power of these lasers is usually under 250mw. the main point differentiating low level lasers and high power ones is the activation of photochemical reactions without heat formation. the most important fact...

Soft robotics offers the unique promise of creating inherently safe and adaptive systems. These systems bring man-made machines closer to the natural capabilities of biological systems. An important requirement to enable self-contained soft mobile robots is an on-board power source. In this paper, we present an approach to create a bio-inspired soft robotic snake that can undulate in a similar ...

In this paper, a new power control scheme is proposed for optimizing the power division between the BSs in the active set during soft handover. In stead of splitting the power equally between the BSs in the active set, it controls the power division according to the propagation attenuation of each radio channel. The optimized power control minimizes the interference and maintains getting benefi...

This paper presents the Zero-Voltage Switching (ZVS) performance of Dual Active Bridge (DAB) DC-DC converter for high power density aerospace applications. Switching transitions of the transistor occurring in favorable conditions such as device zero-voltage or zero-current is called as soft-switching. The benefits of soft-switching are reduced switching losses, switch stress, low electromagneti...

Governments may also use religious soft power in pursuit of national interests and objectives. This article focuses on the role of religious soft power in the foreign policy of three states – the United States of America, India and the Islamic Republic of Iran. The main concern is to assess religious actors’ contribution to the foreign policy environment and agenda in each country. The idea of ...

This paper presents the characterization of power control in WCDMA systems. We know that CDMA is an interference limited system. It is shown that the unbalance scheme is reliable and successful for both 2-way and 3-way soft handover. Unbalance scheme minimizes interference and speed up the soft handover algorithm to support more users quickly. Furthermore it requires minimum time to make decisi...

in this work, we define a fuzzy soft set theory and its related properties. we then define fuzzy soft aggregation operator that allows constructing more efficient decision making method. finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.
