With the steep increase in wireless devices, requirement of spectrum has increased for communication. However, despite huge demand, available is underutilized. The cognitive radio network (CRN) more challenging environment as compared to conventional mobile ad hoc because node mobility and dynamic channel availability. Therefore, we propose a localized clustering scheme, which aims provide better stability, scalability, efficient management, reduce communication overhead. Each computes its...

In the present work, effect of pouring temperature (650°C, 655°C, and 660°C) on semi-solid microstructure evolution in-situ magnesium silicide (Mg2Si) reinforced aluminum (Al) alloy composite has been studied. The shear force exerted by cooling slope during gravity driven flow melt facilitates formation near spherical primary Mg2Si Al grains. Shear along grain fragmentation have identified as responsible mechanisms for refinement grains with improved sphericity. Results show that, while...

Abstract Additive manufacturing has the potential to develop three-dimensional customized components directly in a layered fashion. One of major challenges is surface roughness fabricated by this process. An experimental investigation into effect cryogenic grinding on characteristics direct metal laser sintered (DMLS) Ti-6Al-4V alloy been performed. Before experimentation, DMLS were heat-treated at 800 °C for 1.5 h relieve residual stresses generated during fabrication. The morphology,...

Additive manufacturing (AM) is used for the fabrication of solid components complex geometries customized applications. However, AM-fabricated frequently require finishing operations such as abrasive grinding, which causes a different surface characteristic compared to conventionally manufactured components. Thus, it essential study effect process parameters and heat treatment on quality AM because these may behave differently conventional In this study, characteristics samples Ti-6Al-4V...
