The global electrical energy consumption is steadily increasing and the installed classical high power stationeries cannot fulfill the demand on the other hand, continuous decrement of fossil fuels make incentives to invest alternative energy sources like wind power. Generally Squirrel Cage induction generator (SCIG), Doubly Fed Induction Generator (DFIG) and Permanent Magnet Synchronous generator (PMSG) are used in the wind power generating systems. Individual power coefficient is calculated for different tip speed ratio at fixed rotor speed for the above mentioned generators. A comparative efficiency performance has also been carried out in this paper and the most efficient turbine generator is found.

Natural dye sensitized solar cells (DSSC) have been widely investigated as a next generation solar cell because of their simple structure and low manufacturing cost. In the present work betacyanin dye responsible for the red color of many fruits and leaves having favorable absorption spectra with the solar spectrum has been used in fabrication of solid state dye sensitized solar cell. A Nanocomposite polymer electrolyte consisting of Poly vinyl alcohol (PVA), Lithium acetate, Ethylene carbonate (EC) and Propylene carbonate (PC) with TiO2 filler was used as a solid state thin film electrolyte for betacynin based Dye Sensitized Solar cell. The nanocomposite polymer was complexed with ammonium iodide and iodine crystals were added to the polymer electrolyte. The DSSC with the nanocomposite polymer electrolyte showed good photovoltaic performnance including short circuit photocurrent density (Jsc) 9.8 mA cm-2, the opencircuit volyage (Voc) 0.435 V, the fill factor (ff) of 52% and the conversion effeciency (η) of 2.2% under AM 1.5.

Cloud Computing is a computational framework that provides collection of virtualized resources as Service. Cloud computing is highly profitable cost effective services in the business world in the present day scenario. However, the energy consumption of Data Centers is the big problem emerging out of growing demand for cloud services. That type of critical issues not only reduces the profit margin, but also has effect on high carbon production which is a harmful for environment and living organisms. On the other hand, Green Computing is an overwhelming need based environment friendly computational framework empowered by low emission rate. The basic principles of Green computing is directed towards environment friendly computation. In this paper, a Green cloud enabled framework has been proposed which envisioned the energy efficient way of a minimal discharge and rectification of the problem of high carbon production so as to increase the profit margin. The profitability may not always be expressed with respect to revenue but in terms of bio and environment friendliness. The target is to merge the Cloud Service with the green cloud computational frame work for the future research.

This paper presents a CFD based 3-D numerical simulation of steady turbulent flow in the passage of a Francis turbine. The performance parameters under different operating conditions have been analyzed using available CFX code. The five different operating conditions from part load to over load of a Francis turbine are investigated and results are presented in the form of efficiency and head loss. It has been observed that head losses are minimum and efficiency is maximum at rated discharge and rated head. An attempt has been made to compare the computed results with the available model testing results. The numerical results are found to be in good agreement with the model testing results.

At the end of the solar module manufacturing process, an I-V measurement is performed under different illumination of each individual solar module to determine its current Imp and voltage Vmp at the maximum power point and the ISC and VOC points, where the power will be zero and the maximum value of power will occur between the two. The Fill Factor (FF) is essentially a measure of quality of the solar sell. When calculated the performance of the solar cell from I-V Characteristics using the conventional method, it was found that noise caused the I-V curves to zigzag slightly near the VOC and to zigzag widely near the `knee' of the curve. Defining the exact value of solar Module's parameters is called Module's Characterization. So in this paper the authors are tried to minimized the noise of I-V curve to get the highest power output using Automatic electronic load regulator and also find out a real value of ISC and VOC points from the I-V curve plotting using ATMEGA Microcontroller.

There is rapid growth in demand for air conditioning due to rising population and economic development. This technology should diversify and utilize alternative source of energy like solar energy for sustainable development. Liquid desiccant based air conditioning system (LDAC) is adaptable to solar thermal energy and has advantages like high density energy storage and low regeneration temperature. Regenerator in LDAC system removes moisture from LD absorbed in air dehumidifier. Various regenerators in literature like air scavenging regenerators and collector cum regenerator are discussed. These regenerators are compared and their pros and cons are given. The paper presents the topic in digestible form and provides a perspective to a professional in the field or a person who would like to start doing research in the field.

This paper presents on the continuous conduction mode (CCM) of operations of a flyback SMPS and stability analysis based on inclusive study and operating dogma. The modeling of the SMPS enlightens the stability with the power components and feedback loop. It is worked out by unbreakable poles and zeros of the transfer function of the SMPS, since the coupled inductor in the CCM is palpably a current source and the dominating pole is just the broken by the output capacitor and load resistor. This prediction predicts the upper limit of phase shift that is about 90 degrees of the closed loop stable operation.
