The present work investigate on parametric study and optimization of process parameter in resistance spot weld efficiency of chromate micro-alloyed cold rolled mild steel sheets using L25 Taguchi design of experiments. The output responses are being studied as tensile shear strength of the weldment and nugget diameter which is affected by the input variables like weld current, electrode force and weld time. Both output responses were optimized to achieve effective values by using conventional Taguchi based Grey Relational Analysis and a Metaheuristics method as Genetic Algorithm. Here in present work two main goals specifically tensile shear strength and nugget diameter simultaneously optimized using multi-objective genetic algorithm. The analytical results were validated with experimental run so to analyze the efficiency of methods.Keywords
Genetic Algorithm, Grey Relational Analysis, Orthogonal Array.

An equation has been developed to measure the efficiency of PV module instantly, if the climatic parameters of the area are known. The measured and calculated values of efficiency are verified to check the percentage error between them. It is observed that developed equation has very correlation with the measured values.Keywords

The production of PV power depends on different meteorological parameters. Accumulation of dust is one of the factor which reduces the output power. The recent study was done in Tripura, India and there is maximum of 13% and minimum of 9% reduction in efficiency has been observed during the period of experiment.Keywords
