CONSTRUCTION OF SOMOMETER AND DETERMINATION OF SOUND VELOCITY IN AIR: In a Sonometer, one or more (allowing simultaneous comparison), strings, fixed at both ends, are stretched over a sound box while one or more movable bridges are manipulated to demonstrate mathematical relationships between sound frequencies. "With its single string, movable bridge and graduated rule, the monochord straddled the gap between notes and numbers, intervals and ratios, sense-perception and mathematical reason." However, "music, mathematics, and astronomy were [also] inexorably linked in the monochord...{read more to download full material}
0590]. DESIGN AND CONSTRUCTION OF A SOLAR STANDING FAN:This work is on solar standing fan. The project involves using solar energy to recharge power standing fan. Rechargeable solar standing fan, charges with solar energy. Standing solar fan operated either by solar panel and battery. Solar panel charges the battery during the day while the rechargeable supplies the energy stored in the battery to the fan during the night...{read more to download full material}
0591]. DESIGN AND CONSTRUCTION OF A SOLAR SPRINKLER IRRIGATION SYSTEM: Costs of diesel for irrigation systems are increasing sharply due to the lack of availability of diesel in the markets. Moreover, the use of diesel fuel is also more expensive in the “new lands” due to the remoteness of desert farms. Taking into account the costs of transportation of diesel, maintenance and overhauling of generators, using diesel will no longer be economically feasible or affordable for those farms in the near future. At the...{read more to download full material}
0592]. DESIGN AND CONSTRUCTION SOLAR RECHARGEABLE AC LANTERN USING LED: The lamp operates on electricity from batteries, charged through the use of solar photovoltaic panel. Solar-powered household lighting can replace other light sources like candles or kerosene lamps. Solar lamps use renewable energy with infinity supply which is cheaper than standard lamps. In addition, solar lamps reduce health risk as kerosene lamps have a bad impact on human health. However, solar lamps may have higher initial cost, are weather dependent...{read more to download full material}
0593]. SOLAR PRINCIPLES AND DESIGN OF SOLAR PANEL: Sunlight is a form of radiant energy that travels to the earth as electromagnetic waves. In reality, the light we see is just a small part of the energy we receive from the Sun. The radiant energy from the Sun covers the full breadth of the electromagnetic spectrum. Using solar technology, we are able to "capture" the Sun's radiant energy and convert it to either heat or electricity. This sun is captured using solar panel, which is a set of solar photovoltaic (PV) modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions (STC)...{read more to download full material}
0594]. DESIGN AND CONSTRUCTION OF A 12VDC TO 220VAC SOLAR INVERTER: This work is on design and construction of a 12VDC to 220VAC solar panel. Solar inverter converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. In solar inverter, Solar panels produce direct electricity with the help of electrons that are moving from negative to positive direction. Most of the appliances that we use at home work on alternative current. This AC is created by the constant back and forth of the electrons from negative to positive. In AC electricity the voltage can be adjusted according to the use of the appliance. As solar panels only produce Direct current the solar inverter is used to convert the DC to AC...{read more to download full material}
0595]. DESIGN, CONSTRUCT AND PERFORMANCE EVALUATION OF A THERMOELECTRIC GENERATOR:Energy crisis and environment deterioration are two major problems for 21st century. Thermoelectric device is a promising solution for those two problems. Thermoelectric generator (TEG), is device that convert heat energy into electric energy. This generator accomplish this task by using arrays of specialised circuits known as thermoelectric modules, each of which consists of semiconductor materials-known as p-type and sn-type -sandwiched between insulating ceramic substrates. This work deals on thermoelectric power electricity...{read more to download full material}
0596]. DESIGN AND CONSTRUCTION OF AN ARDUINO BASED SINGLE PHASE AUTOMATIC CHANGEOVER SWITCH: An Automatic Changeover Switch switches off the generator and automatically changes over to NEPA. An Automatic Changeover Switch will automatically switch off your generator and change over to MAIN ( Public power supply/NEPA) on resumption. You will save fuel and no risk of electrocution. It also serves as power surge protector for appliances. The main aim of any electric power supply in the world is to provide uninterrupted power supply at all times to all its consumers. Although, in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient, hence power instability and outage...{read more to download full material}
0597]. TRANSMISSION LOSS MINIMIZATION FOR POWER SUPPLY EXPANSION AND PLANNING USING DISTRIBUTED GENERATION (DG): The epileptic power supply from the national grid due to instability is a concern to energy consumer. This instability in power supply experienced in power transmission network could be minimized by introducing distributed generation (DG). The goal of this work is to calculate the total loss in the system and minimize this loss by implementation of distributed generation (DG) technology ...read and download
0598]. DESIGN AND CONSTRUCTION OF A REMOTE CONTROLLED 3KVA PETROL GENERATOR: The paper presents the design and construction of an infrared remote controlled petrol generator, which is a device that enables the user to operate or control the ON and OFF supplied of a generator from approximately 5 to 10 meters away. The remote transmits a beam of light using an infrared light emitting diode; this light is picked and decoded by the receiver unit (Photodiode). The receiver only activates when it receives the beam of light, there are no accidental activations...{read more to download full material}
