Abstract: Adaptive on-chip verbal exchange is crucial to the layout of multi-center System-on-chip. Wormhole routers offer an powerful mechanism to alternate information a number of the more than one cores inside the NoC. Efficient packet allocation can improve the performance of adaptive wormhole routing with the aid of prioritizing uncongested packets to reach their destinations first. This paper gives a routing method that collects site visitors/congestion data, and employs it to prioritize lengthy distance visiting packets throughout excessive congestion. Each NoC router collects site visitors/congestion statistics from its close by routers and makes routing decisions to pick some packets for visiting...................

Abstract: Metamaterials are a recent area of research that are important in a wide range of applications such as antenna, cloaking devices(invisibility), observer of light, super-lens, invisible submarine. This has attracted researchers both from industry and academia from the last few decades. The literature presents quality work that has been done in this direction. The paper presents a review of how metamaterials can be used as an energy storage device and can be used if needed in future. It proves to be an edge over the existing conventional techniques..

Abstract: This paper presents the design and simulation of micro strip patch which involves the geometry of flipped swastika carried out on a rectangular patch. The proposed antenna structure is designed for Wi-Max application. The patch is cut in proposed shape to ensure improved results in terms of bandwidth and gain. Strip line feeding is given and the results are calculated for VSWR and return loss. The simulation and optimization is carried using HFSS software.
