An Arithmetic Logic Unit (ALU) is an integral part of a computer processor. It is one of the most frequently accessed modules in a CPU and is utilized during most instruction executions. It has the capability of performing no. of different arithmetic and logic operations such as addition, subtraction, multiplication, bit-shifts and different logic operations. This paper primarily deals with the construction of Arithmetic Logic Unit (ALU) using Xilinx VIVADO 2016.2 and implement them on Field Programmable Gate Arrays (FPGAs) to analyze the design parameters. The main objective of designing the ALU is to develop algorithms in order to achieve an efficient utilization of the available hardware. The measures of the efficiency of an algorithm are speed improvement, less power consumption and better utilization of ALU. In this paper, we have simulated and synthesized the various parameters of ALUs by using VERILOG on Xilinx Vivado2016.2 and BASYS3 FPGA board [1].

Dry type transformer is a popular choice for application wherein flame-retarding, self-extinguishing and low- maintenance is desired; e.g. wind turbines, underground- substations etc. As their makeup involves no-oil, the cooling of coils is essentially by natural convection of air. With increase in demand for higher-ratings and stringent limitation on coil temperature rise, convectional design of thermal management has severe limitation on meeting these requirements. Also, conventional approach of thermal management leads to increased equipment cost and foot-print. This paper discusses a novel methodology of improving the heat dissipation in dry transformers with low- cost retrofit-able systems that increase the heat dissipation rate significantly.

In the area of farming, use of appropriate method of irrigation is crucial and it is clearly defined that drip irrigation is highly commercial and effective. In the normal conventional drip irrigation system, the farmers have to regularly keep an eye on irrigation schedule and timetable, which is varied for diverse crops. The central theme of the paper makes the irrigation automated. The use of low budget sensors and the small control unit makes this venture a low budget solution, which can be subscribed even by a meager agriculturalist. This idea is best suited for the places where scarcity of water takes place and it, also, has to be used in restricted quantity. Any states of India and the rest of the world can afford this modest and low budget solution for irrigation and obtain good yield on Crops.

This study presents a power management scheme for application in hybrid electric vehicle (EV) systems. For various advantageous features like, high efficiency, and high reliability photovoltaic (PV) system is chosen as the main power source of EV. However, according to mitigate the intermittency problem of solar cell, auxiliary source is required to be incorporated along with PV. Hence, an energy storage system (Battery) is associated with the PV system which can ensure an uninterrupted power supply. Through the bidirectional DC-DC converter battery cells are used to store excess solar energy and provide them to the load when required. As per requirement the battery is charged and discharged by controlling the operation mode of the bidirectional converter i.e. bucking and boosting, respectively. The MATLAB simulation results are presented to show the behavior of the responses even in presence of variation in load as well as in different illumination condition of PV module.

GPS, a standardized and matured satellite based navigation system, having a broad range of applications. It is widely preferred due to its fast and better performances. The accuracy of a GPS system is an important issue in PNT service to all the dependents, which is limited by geometry of visible satellites. With the advent of multiple constellations, research work is continuing to combine different constellations to get good geometry i.e. Dilution of Precision (DOP). In this research work, GPS and NavIC (Navigation Indian Constellation) constellations are combined to investigate the DOP values for the receiver located at GPCET (15.790N, 78.070E), Kurnool, India. GDOP is an instructional parameter as it specifies error in 3D position and time. In urban environments the GPS or NavIC users would be able to pick the satellite signals of higher elevation because of the obstructed sky view. In case of higher elevation mask angle (300) mean GDOP is 19.22 by GPS alone and 3.44 by the combined constellation (GPS+NavIC). Hence, the combination of GPS and NavIC is more preferable to get good geometry to improve the accuracy of PNT services in and around Indian region.
GPS是一种标准化、成熟的卫星导航系统，具有广泛的应用前景。由于其快速和更好的性能，它被广泛使用。GPS系统的精度是面向所有依赖者的PNT服务的一个重要问题，这受到可见光卫星几何形状的限制。随着多星座的出现，研究工作仍在继续，将不同的星座组合在一起，以获得良好的几何形状，即精度稀释(DOP)。在本研究中，结合GPS和NavIC (Navigation Indian Constellation)星座，研究了位于印度Kurnool GPCET (15.790N, 78.070E)的接收机的DOP值。GDOP是一个指导性参数，因为它指定了3D位置和时间的误差。在城市环境中，GPS或NavIC用户将能够选择较高海拔的卫星信号，因为天空视野受到阻碍。在高程掩模角(300)较高的情况下，GPS单独的平均GDOP为19.22,GPS+NavIC组合星座的平均GDOP为3.44。因此，GPS和NavIC的结合更有利于获得良好的几何形状，以提高印度地区及其周边地区PNT服务的精度。

A new modular three phase topology is proposed for Power Factor Correction (PFC) that features high voltage gain. This proposed three phase converter consists of switched capacitor cell in each module. In the proposed topology, all components have voltage stress equal to half of the output voltage. This converter features modular structure, less voltage stress across the active components, high voltage gain, good power factor. Average current control is implemented to have unity power factor and low harmonic distortion. MALAB/SIMLINK study has been carried out to ascertain the performance of the proposed converter.

With the increased share of renewables in power generation grid tied multilevel Inverters find a greater use. The vector control scheme has been implemented in the reference frame rotating at synchronous speed based on the independent control of real and apparent flow of power from the inverter to the grid. The currents injected in to the grid are controlled with two current control loops, one for the direct axis and other for the quadrature axis. Here, a lag compensator is taken as a controller technique for grid interface inverter to mitigate the power quality issues. The Insulating Gate Bipolar Transistor has forms as semiconductor switch for the parallel connected Voltage Source Inverter. The switching control employs SPWM technique in which a high frequency carrier is modulates with sinusoidal wave of grid frequency. The mathematical model of the inverter and its operation for power quality improvement has been validate and represents by the simulation.
