ABSTRACT In this investigation, 316L stainless steel, one of the three metal alloy grades used as a biomaterial, is produced by a selective laser melting process (SLM) of additive manufacturing. Static properties and microstructures including fracture morphologies were investigated as a function of build angles of 0, 30, 60, and 90 degrees. Static properties, namely […]

ABSTRACT We analytically explore the high optical performance of an ultrathin amorphous silicon (a-Si) solar cell by rigorous coupled wave analysis (RCWA) method. By studying the absorption spectrum and field intensity profiles, we have investigatedthe importance of the grating structure via scattering and diffraction mechanism. Asignificant improvement is observed with the cell efficiency(η) as high […]

ABSTRACT The cupola is a refractory lined shaft furnace and the basic fuel is coke. The main objective of the present work is the utilization of waste material (Rice husk briquette) of low C.V. to 50% eq. of split coke charge. Bed coke remains unaltered due to breakdown of rice husk briquette on heating in […]

ABSTRACT Flexible AC Transmission System (FACTS) is a progressive technology that has allowed power system utilities to make the most out of the existing grid and control the governing parameters that affect the power flow and/or stability of the transmission and power system broadly.  One of the most important FACTS devices is Unified Power Flow […]

ABSTRACT Now-a-days with the improvement of technology, the demand for electric power is increasing at a growing rate. Many consumer appliances demand quality improvement in power constantly for their operation. The performance of the end user accessories dependent on the quality of power supplied. But the quality of power delivered to the consumer is affected […]

ABSTRACT Static properties, microstructure and fracture morphologies of a near-eutectic aluminium alloy produced by a laser additive manufacturing (LAM) method were investigated. Laser powder bed fusion process was used to 3D-print tensile test specimens at 0, 30, 60 and 90-degree build angle orientations, with known processing parameters. Tensile tests were conducted on MTS Landmark servo […]

ABSTRACT Every nation strives hard to achieve economic development for which adequate infrastructure is required to accomplish the desired goals. In mountainous terrain, road and highway networks play an important role for transportation, public conveyance and other socio-economic activities. Infrastructure development in hilly areas warrants excavations for the construction or road widening purpose undermining the […]

ABSTRACT Flexible AC transmission system (FACTS) devices are widely used in power system. They have characteristics to perform faster and can solve many problems in power system study. With regards to this, a particle swarm optimization (PSO) algorithm is applied so that to design the coordinated parameters of static VAR compensator (SVC) and Thyristor Controlled […]

ABSTRACT The aim of this paper is about single screw extrusion graphical modeling, and automation. At plastic era, industrial processes of polymer shaping are becoming more and more complex, with an increasing demand in terms of safety, robustness, productivity gains and quality. This implies a new integrated automation design which is no longer limited to […]

ABSTRACT Exhaust gas recirculation (EGR) is widely adopted to reduce the oxides of nitrogen (NOx) emission. This involves recirculation a controllable proportion of the engines exhaust back into the intake air. Present experimental study has been carried out to investigate the effect of EGR on performance and emission characteristics in a direct injection diesel. A […]
