Fiber Reinforced Self Compacting Concrete (FRSCC) is a composite material consisting of cement based matrix with an ordered or random distribution of fiber which can be steel, nylon and polythene, etc., which offers several economical and technical benefits. In this study, domestic waste plastics (Polythene fibres) were used and the properties of concrete (viz., compressive strength, flexural strength, split tensile strength) are studied. The tests have been carried out as per EFNARC for fresh concrete and Indian Standard Code for hardened concrete. © Medwell lournals, 2012.

Network on Chip (NoC) router plays a vital role in System on Chip (SoC) applications. Routing operation is difficult to perform inside the SoC chip. Because it contains millions of chips in one single Integrated Circuit (IC), in which every chip consists of millions of transistors. Hence NoC router is designed to enable efficient routing operation in the SoC board. It produces more delay to find the priority, which comes from various input channels. And more area is consumed in unidirectional router. Also if any path failure occurs, it cannot route the data through other output channel. To address this problem, a novel bidirectional NoC router with and without contention is proposed, which offers less area and high speed than the existing unidirectional router. The proposed bidirectional router can route the data from any input channel to each and every output channel. So it avoids conflict situation and path failure problems. If any path fails, immediately it will take the alternative path through the switch allocator. Simulation is performed by ModelSim6.3c and synthesis is carried out by Xilinx10.1. The proposed bidirectional NoC router is implemented in FPGA Spartan3 to verify their performance. Our results prove that the proposed bidirectional router is suitable for high frequency operation, minimum delay and small in size on-chip network design. © Research India Publications.

Fiber Reinforced Concrete (FRC) is a composite material consisting of cement based matrix with an ordered or random distribution of fiber which can be steel, nylon, polythene etc. The addition of steel fibre increases the properties of concrete, viz., flexural strength, impact strength and shrinkage properties to name a few. A number of papers have already been published on the use of steel fibres in concrete and a considerable amount of research has been directed towards studying the various properties of concrete as well as reinforced concrete due to the addition of steel fibres. Hence, an attempt has been made in the present investigations to study the influence of addition of polythene fibers (domestic waste plastics) at a dosage of 0.5% by weight of cement. The properties studied include compressive strength and flexural strength. The studies were conducted on a M20 mix and tests have been carried out as per recommended procedures of relevant codes. The results are compared and conclusions are made. © 2006-2011 Asian Research Publishing Network (ARPN).

Technology scaling has led to the integration of many cores into a single chip. Multiprocessor Network-on-Chip (NoC) seems to be a good solution for the higher performance desired VLSI designs. The main challenge is how to enhance the communication efficiency in NoC. The NoC is a new paradigm which is fast emerging at present. The performance of the on-chip-networking depends on routing techniques used in the system. The existing techniques such as Round Robin Arbitration are not so efficient in finding an optimal path. The authors have chosen a different routing algorithm called Optimal Address Based Router (OAR) to find an optimal path which has low overhead. In this paper, we have reported a comparative evaluation of Optimal Address Based NoC router and Round Robin Arbitration based NoC router. The simulated results indicate that the Optimal Address Based NoC router is a better choice. The implementation is done on FPGA Spartan 3Xc 3s400 board. Further analyses of results shows that the optimal address based router consumes 71% lower power, occupies 90% less area and is faster by a factor of 35%. © 2014 IEEE.

Solar Energy | Year: 2013

Many types of solar air heaters have been developed in India and their performance has been studied in detail. In solar dryers the drying process largely depends on the varying local weather conditions, resulting in a poor quality of the dried product. To eliminate the fluctuations in the temperature of the hot air, solar collectors are integrated with the Phase Change Material (PCM) based thermal storage unit. The present study is aimed at investigating the feasibility of using a latent heat storage unit with HS 58, an inorganic salt based phase change material, to store the excess solar energy, and release it when the energy availability is inadequate during poor weather conditions, and to extend the period of utilisation beyond the sunshine hours. Experiments were conducted to evaluate the charging and discharging characteristics of the storage unit. The effects of inlet flow rate during the charging and discharging processes were measured and reported. For the storage tank configuration and PCM ball size considered in the present investigation, the mass flow rate of 200. kg/h is able to provide a near uniform rate of heat transfer during charging and discharging processes. Further, low mass flow rate is able to utilise the maximum capacity of the storage system and to supply heat for a longer duration. © 2012 Elsevier Ltd.
