[1] Review on High Performance Integrated Circuit Transform Finite Impulse Response Module

Anjali Bathma & Shraddha Shrivastava

This paper presents efficient modified distributed arithmetic (MDA)-based approaches for low delay reconfigurable usage of limited motivation reaction (FIR) channels whose channel coefficients change during runtime. Expectedly, for reconfigurable DA-based usage of FIR channel, the query tables (LUTs) are required to be actualized in ROM; and the ROM-based LUT is seen as exorbitant for application explicit incorporated circuit (ASIC) execution. Along these lines, a common LUT configuration is proposed to understand the MDA calculation. Rather than utilizing separate registers to store the potential aftereffects of incomplete internal items for DA handling of various piece positions, registers are shared by the DA units for bit cuts of various weightage. The all plan actualized in Xilinx Virtex-5 FPGA gadget (XC5VSX95T-1FF1136).

[2] Study the variation in Sub ionospheric Very Low Frequency (VLF) Signal during geomagnetic storm

Sakshi Jain, Abhinav Bhargava, D.K Sondhiya & Santosh Jain

The propagation characteristics of subionospheric VLF signal depends in variation in geomagnetic field of earth. For a long propagation path variation in solar zenith angle influence on the VLF signal propagation characterises. To study the effect of variation in geomagnetic field on VLF signal propagation, we study the propagation characteristics of four VLF signals transmitted form VLF transmitter (i.e. ICV, NAA, NRK and TBB) during geomagnetic storm occur on year 2018. We conclude that VLF signals show shift in morning and evening terminator time and spiky nature during all geomagnetic storm under consideration.

[3] Experimental Study Of Design And Fabriction Of Hexagonal Reflector Using Flat Plate Solar Collector

Deepak Kumar Pandey, Dr. Shailendra Dwived & Jitendra Raghuwanshi

The motive of this thesis is to develop and fabricate the Hexagonal reflector solar collector or heater. The collector concentrates the solar energy and converts into the concentrated radiation without using the concave or convex mirrors for heating or heat transfer into the water. The Hexagonal type solar reflector concentrates together direct radiation of the sun toward the collector. For maximizing the intensity of radiation from reflector. which can be adjusted by varying its angle relevant position of sun. The radiation comes from sun's energy was changed into heat and then heat was transferred to the water. A design is proposed and carried out the experiments. As well identify the behaviour of heating through model against of different position of sun and combination of angle. The observation has also considered that the model temperature changes and taken into the part of heat transfer.
