Abstract: The photovoltaic industry requires the cutting of Silicon ingots into wafers to facilitate the manufacturing of silicon with view to achieve higher productivity.. In this study the wire electric discharge machining process(WEDM) was selected for machining of Polycrystalline silicon to study the effect of  various input parameters like Pulse ON time, Pulse OFF time, peak current, wire feed, wire tension, spark gap voltage and water pressure on cutting rate, surface finish and kerf width. The experimental results showed that pulse on time,  pulse off time, spark gap voltage, wire feed and water pressure have significant effect on cutting rate, surface finish and kerf width. The other machining parameters like wire tension and peak current did not have large effect on machining process. The experiments  performed demonstrated that WEDM process can be applied to produce silicon wafers from polycrystalline silicon ingots. Hence the application of WEDM process to the manufacture of solar cells can bring significant enhancement in production efficiency of  solar cells.

Keywords: photovoltaic industry, WEDM, silicon, solar cells.

Abstract: The study is about making a sample Aerosol box which could answer the present problems of the latest Aerosol box especially on its function to trap the breath air of a patient with contagious disease. The study used a thermoelectric device to answer the present problem. The study fabricated a proposed sample Aerosol box that will trap the breath moist. The result of the experiment was that the thermoelectric device that was used is not sufficient to control the temperature and humidity of the bigger room with the dimension of 381 millimeters by 381 millimeters by 381 millimeters. However, when the dimension is shirked to smaller dimension of 101.6 millimeters by 076.2 millimeters by 50.8 millimeters the humidity is controlled.

Abstract: The purpose of this study is to design and develop an air conditioning system with and integrated water dispenser. With this study, by combining these two distinct pieces of equipment, there can be a noticeable amount of energy savings compared to the total energy consumption of an air conditioner and a water dispenser. The researchers made a prototype of this device that is able to produce cold and hot drinking water as in a water dispenser at the same time blowing cool air that is regulated by a thermostat as in an air conditioning system. The researchers used the fundamental knowledge of heat transfer in coming up with the design. In the data gathered during testing phase, the researchers are able to reach the temperatures that conventional water dispensers have after a certain amount of time, while being able to decrease electrical energy consumption. Hence, it can be concluded that this study is beneficial to the people that are in hot and humid areas like the Philippines

Abstract: The purpose of this study is to give knowledge to the Mechanical Engineering Students of the Lyceum of the Philippines University- Cavite on how to design an air conditioning and elevator system for a Research Facility and Administration building located at Freedom Island Trail (Rail Road), Parañaque City, Metro Manila. The researchers believe that the study would broaden the knowledge of mechanical engineering students about the design of Heating, Ventilating, and Air conditioning (HVAC), what are the things need to consider and how to compute the humidity of the facilities. The researchers made a floor plan as to understand how to compute the materials and to determine the length of each components needed. We referred to ASHRAE data guide to compute and practice safety standards. After computation that we held, we the researchers conclude that the assumption of the datum that we gather is relevant to the real works of the real project.

Abstract: Electrical Discharge Machining (EDM) is a machining process used for producing complex metal fabrication that cannot produce using conventional machining processes. Proper selection of material is important for the benefits of the machining rate. Good selection of material leads to better performance. The present study mainly focusing on copper as the electrode. The objective of this is to assess the wear rate of the copper on AISI 4340 alloy steel and output parameters such as pulse current, pulse on time, and pulse off time.

Abstract: Areca nut fibers and Areca nut fiber with Glass fibers are reinforced with epoxy matrix and composites have been developed by hand lay-up technique. The effect of areca nut and Glass fibers on mechanical properties of epoxy composites was studied. The mechanical properties include tensile and flexural properties as per ASTM standard Procedures. The analysis continued to evolve a comparative study of pure Areca nut fiber and hybrid Areca nut & Glass composites. The results revealed that incorporation of glass fiber in Areca nut fiber improved the mechanical properties of the composite in a greater extent.
