Effect of Thermal Conditions on Microstructure and Mechanical Properties of AA5083 Processed by Equal Channel Angular Pressing
Abstract: A commercial AA5083 with an initial grain size of 210 μm was given an ultrafine-grained structure using the equal channel angular pressing (ECAP) technique under die design as patented. The identical sample underwent two successful passes through the die at 473 K, with each passage causing the sample to rotate 90° along its own longitudinal axis. After just one pressing, the microstructure was comparatively homogeneous. It was made up of …

Congenital Heart Disease (CHD) Detection Technique Based on Analysis and Classification of ECG Signal
Abstract: As per American Heart Association information, every year 125 babies out of 1000 are born with congenital heart disease (CHD). It was estimated that 36000 children are live born with CHD each year in the European Union. Child with CHD may have hole in heart up to 3–5 mm as small defects and for large defects it may go up to 5–8 mm. Depending upon the size of hole in …

A Review of Fire Retardants for Commercially Important Polyurethane Foams
Abstract: The review covers various additive and reactive fire retardants used to render flexible and rigid polyurethane foams fire retardant. Literature sources are mostly from technical publications, patents, books and handbooks since 1962. Various fire retardants such as phosphorus-containing compounds, halogen-containing compounds, nitrogen-containing additives, silicone-containing products and miscellaneous organic and inorganic additives have been used to render polyurethane foams fire retardant. Some heatresistant groups such as carbodiimide, isocyanurate and nitrogen-containing heterocycles …

A Review of Single-Phase Grid Connected Transformerless Solar PV Inverter Topology
Abstract: Abstract: Owing to low cost and system compactness, transformerless inverters became popular in single-phase grid connected photovoltaic (PV) systems. Improvement of conversion efficiency, reduction in distortion of the grid current and minimizing common mode leakage current are the major concerns in these inverters. The purpose of this paper is to review on various transformerless solar PV inverters. In this paper, the single-phase inverters are classified into two major categories: 1) …

Solar Charkha Retrofit
Abstract: Hand operated charkha is used to make thread from cotton. It is sensitive work and involves great deal of care and effort to spin the charkha wheel manually during thread extrusion. Charkha operation causes physical strain and fatigue in long run. Abrupt spinning creates thread knots and breakage thus results poor quality and cotton wastage. Large number of people board on this khadi profession to make their meager earnings and …
