In the Spark Erosion machining process, electrical energy in inter-electrode gap gets converted into thermal energy. Whatever generated inter electrode distributed among anode, cathode and dielectric fluid. The workpiece spark erosion process is kept as anode fraction of total which going to (workpiece) should be maximum. As this responsible for melting material on workpiece. This important par...

The optimum thickness of the building envelope insulation materials depends on a large number of parameters. But the optimum thickness is calculated considering only economic arguments. In this paper, life-cycle assessment of the materials used in the building, and specifically the insulation ones, are included in the process to calculate the optimum insulation thickness from both environmental...
