Rural Electrification by Solar Power LED's

Around 25,000 villages are located in remote and inaccessible areas and hence could not be electrified through conventional grid extension in India. The functionality of the system varies across the placed and across the seasons. During rainy season on an average one luminary works 2 to 3 hours. During winter and summer on an average one luminaire works 4 to 5 hours. However, performance declines over the years. Use of kerosene is reducing in rural areas. Nearly 53 to 69 percent reported that there is significant improvement in their children's education, and 37 to 78 per cent reported that there is improvement in the standard of living after the installation of solar lighting by LED's. Beneficiaries now spend more time on income generating activities.

Crime rate has also declined due to availability of solar street lights in the village. A basic system consists of a small solar panel, a battery, a charge controller, LED lights, and a universal outlet for charging cell-phones or other small appliances. This approach differs from the many for-profit organizations, who use conventional business strategies, simply importing their technology and sell the product with financing to those who can afford it. My community centered capacity building strategy differs from current industry players in that it allows for increased local capacity and empowerment.[1].

Implementation of TI-SEPIC Converter for Optimal Utilization Of PV Power

In this project qualitative analysis and controller design of a TI-SEPIC converter for optimal utilization photovoltaic power is presented. This converter is essentially combination of conventional buck and SEPIC converters sharing common components. On the account of the integration load side only one inductor is sufficient enough for performing the power conversion in both Buck and SEPIC converters. Here the function of the lower SEPIC converter is to extract maximum power from the PV and feeds into the load, while the remaining load power demand is supplied by the dc source through a voltage-mode controlled buck converter. Proposed integrated Converter performance is verified through MAT/SIM software simulations and then verified with measurement results obtained the laboratory prototype converter system.

Performance Analysis of Bayesian Methods to for the Spectrum Utilization in Cognitive Radio

Cognitive radio is an exciting wireless technology that has been introduced for the efficient used of spectrum. Using cognitive radios (CRs), the secondary users (unlicensed users) are allowed to use the spectrum which is originally allocated to primary users (PUs) as far as the active primary users are not using it temporarily. In order to prevent harmful interference to primary users, the SUs need to perform spectrum sensing before transmitting signal over the spectrum.

In this paper we use an optimal Bayesian detector for digitally modulated primary user to improve the spectrum utilization, without prior knowledge of transmitted sequence of the primary signals. And further suboptimal detectors in low and high SNR regime. We provide the performance analysis in terms of Detection probability and False alarm probability.

Use of Demorlished Concrete in Pavement

Recycled aggregates consist of crushed, graded inorganic particles processed from the material that have been used in the constructions and demolition debris. The target of the present thesis work is to determine the strength characteristic of recycled aggregates for the application in concrete pavement construction. The scope of the thesis is to determine and compare the compressive strength, flexural strength and sulphate resistance of concrete by using different percentages of recycled aggregates.

The investigation was carried out by using workability test, compressive strength test, flexural strength test and sulphate resistance test. A total of five mixes with replacement of coarse aggregates with 0%, 10%, 20%, 30% and 40% recycled coarse aggregates were studied. The water cement ratio was kept constant at 0.38. It was observed that workability of concrete was decreased with the increase in recycled aggregates in concrete. For the strength characteristics, the results showed that the strengths of recycled aggregate concrete was comparable to the strengths of natural aggregates concrete.

Green Plastics: Poly-lactic Acid Synthesis from Waste Tamarind Seed Powder & its Applications

In the era of sustainable development there is a necessity to produce biodegradable polymers to minimize the soil pollution. With the need of the hour Green plastic is the polymeric material formulated for specific applications, which is derived from the Tamarind seed de-oiled cake starch. Through the series of unit operations, starch which is produced can be fermented by Lactobacillus delbrueckii, Lactobacillus amylophylus and Lactobacillus amylovirus. The polymerization reaction of Lactic Acid is carried out by using a catalyst. To cope up with the scarcity of valuable petroleum product & to minimize the environmental pollution, Green plastic materials play an important role for sustainable development.
