Maximum Power Point Tracking Using PSO with Boost Converter
Abstract: Maximum power point tracking methods are used for extraction of maximum power from solar PV panels. The characteristics of non-line panel hinder the power output from the solar panel. Earlier proposed methods like hill climbing, incremental conductance suffer from steady state and lower efficiency. This proposed evolutionary computation technique assures nearly zero steady state oscillation and faster convergence of tracking maximum power. The PSO algorithm is tested on a DC-DC …

Review on Drying of Tea Leaf during Manufacturing Process.
Abstract: India is the world's largest tea producer, and Assam contributes about 55 per cent of India's total production making it the largest tea growing area in the world. Tea production started in the early 1800s, during the British period. Maniram Dewan was Assam's first tea-maker. In the first two decades (1840–1860), the cultivation and production of Assam tea was monopolized by the Assam Company, which worked in Upper Assam districts …

Crosslinked Starch Polymer for Coating on Fruit/Vegetable for Preservation Derived from Waste De-Oiled Soybean Cake
Abstract: Cross-linked starch films have been prepared by reacting starch extracted from de-oiled soybean cake (waste material from oil industry) with bio-based acids citric acid and tartaric acid. The obtained films were characterized by spectroscopic, thermal and surface morphological techniques. Thermal analysis showed that thin film has good thermal stability. The micrographs obtained from scanning electron microscopy showed the film surface has smooth and uniform morphology. Biological properties like cytocompatibility, antimicrobial …
