ABSTRACT: Maximum Power Point Tracking (MPPT) is the most important part of an energy conversion system using photovoltaic arrays. Maximum power point tracking (MPPT) techniques are used in photovoltaic (PV) systems to maximize the PV array output power by tracking continuously the maximum power point (MPP) which depends on panel temperature and on irradiance conditions. … Read more

INTRODUCTION 1.1. General Humans every day sees strange disasters around the world such floods, deadly diseases, environmental pollutions and building burning. Buildings exposed to direct fires for periods long enough to deteriorate concrete membersdifficultto be completely rehabilitated again. High strength concrete has diverse strength loss when subjected to thermal loads and shows a higher tendency … Read more

Delco-Remy started to test in 1948 for first electronic ignition system, whilst Lucas started to perform in 1955 for transistorized ignition system. It was used for formula one engine in 1962. After sales of existing power transistor 201 and Autolit (capacitive discharge thyratro’s) Tung-Sol E-4 and E began offering later that year. Pontiac optional EU, … Read more

Present industrial scenario requires any engineering structure to be designed considering stability of several parameters at the operating conditions (e.g. Temperature, pressure, resistance to mechanical and surface degradation, etc.). Choice of materials for any engineering component should be such that it operates safely for reliable function; without failure during in-service, giving optimum component life. Due … Read more

The effective length of the radiating slot is used to determine the resonant frequency. Effective length of a radiating aperture is used to determine the resonant frequency. The effective length of the slot can be varied by extending or truncating the radiating slot by use of Switches, such as, RF MEMs, PIN diodes and Varactor … Read more

The accuracy of distance protection relays from double-circuit lines is highly influenced by the zero sequence mutual impedance and fault resistance. During earth faults with parallel line operation, the impedance computed by the fault locator of the relay will be inaccurate, due to the zero sequence mutual coupling. Also, the power system state and the … Read more

Turbomachines requires high quality mesh. Because of the complex geometry it is not easy to get this type of high quality mesh, also the time required for carrying out dynamic analysis of such mesh is very high. So in order to be able to carry out large number of analysis it is very necessary to … Read more

Different design can be used for different kind of toilets, for this matter we are looking into different designs for Urine ‘ Diversion Dehydration Toilets (UDD ‘ toilets) and Composting Toilets. The difference between the UDD ‘ toilet and the composting toilet is that the UDD ‘ toilet focus on getting the liquid (i.e. urine … Read more

Ans: Decision Support System introduce to a class of systems which support in the process of decision making and does not always give a decision itself. Decision Support Systems (DSS) are a particular class of computerized information system that supports business and organizational decision making events. The DSS basically helps in the information system in … Read more

Introduction : Modern multi-function test equipment utilize a microcontroller in their designs frequency meters are extensively used in industry for measuring frequency and period of continuous singles .analogue signals are normally passed through a filter and a zero crossing circuit to make the signal amplitude compatible with TTL input of microcontroller provide reasonably accurate result … Read more

2.1 Introduction A Fuel Cell is an Electro-Chemical cell that converts a source fuel into an Electrical current. It generates Electricity inside a cell through reactions between a fuel and an Oxidant, triggered in the presence of an electrolyte. The reactants flow into the cell, and the reaction products flow out of it, while the … Read more

Increases in microprocessor power dissipation coupled with reductions in feature sizes due to manufacturing process improvements have resulted in continuously increasing heat fluxes [1]. The ever increasing heat flux has necessitated the development of new thermal management technologies. Although some of the solutions for high flux cooling problems based on liquid methods such as spray … Read more

In this project we have tried studying about nature of industrial load, designing of a PF corrector for the same and Development of a single phase PF corrector using PIC microcontroller chip. Using PIC microcontroller and sensors it measures and senses the PF of the load. With the help of programming done right it will … Read more

Manholes are underground loads assembled to give man- entry access for the maintenance of sewer and channel lines, water valves, metering gear, and so forth. They are liable to disintegration from ground water interruption, corrosion from fluids and gases and general decay from age. With the introduction of successful manhole repair advancements, the imperfections and … Read more
