Manish Kumar; Abhay Chaturvedi

European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 4, Pages 151-158

The adders are logic circuits designed to execute “high speed Arithmetic operations” in Arithmetic Logic Unit (ALU) utilized in processors. The basic Adders are “Half Adder and Full adder”. The diverse kinds of adders are Carry Look ahead Adder (CLA), Ripple Carry Adder(RCA), Carry Select Adder (CSLA), &Carry Skip Adder(CSKA). In this manuscript, Heterogeneous adder (HA) architecture is designed with support of diverse Homogeneous adders and Heterogeneous adders are contrasted with Homogeneous adders in terms of power, delay, & area. This architecture is based on a VHDL and compares their performance with Xilinx VIVADO software tool.

Synthetic aperture Radar is a two- dimensional radar or three-dimensional radar that plays a prominent role in remote sensing. After many researchers have been done the advanced radar is polar metric synthetic aperture radar. PolSAR radar is fully polar metric radar it provides valuable data on relating experimental target than conventional artificial aperture radar. Therefore, it plays a significant job in numerous grounds like agriculture, military and geology. Based on this classification, ISODATA and minimum distance classification are utilized to explain the spatial and spectral data of polarimetric synthetic aperture radar. The initial step is to create the spatial data utilized for pre- processing stage. The PolSAR image is produced by decomposition and super pixels and then the date is estimated. The next method is to utilize spatial data for post-processing it sustains the minimum distance classification .The result is obtained by minimum distance categorization. The third method utilizes spatial data openly for categorization. In this method, SENTINEL data is applied to classify the PolSAR image. This SENTINEL data is classified by using SNAP software Based on Max-Margin the trademark work is structured and restrictive arbitrary field is utilized to proliferate the logical data in both naming field and perception field. Otherworldly term and spatial term are two significant pieces of the representation

Due to various benefits, Microstrip patch antennas are utilized in different applications extensively. Because of the attractive features of ease of fabrication, robustness, light weight, and low profile, microstrip patch antennas have been investigated. However, the significant disadvantage is the narrow bandwidth that is where stacking of antennas is proposed. The stacked antenna is designed to form an array which is used for enhancing bandwidth. The stacked antenna offers many advantages like miniaturization, frequency independent, wideband and multiband capabilities, low volume, smaller dimension and many more. With a rectangular slot, a rectangular microstrip patch antenna is designed in this project and it is replicated based on HFSS tool. A 1*1, 1*2 and 1*3 stacked antenna designs are proposed using line and coaxial feeding techniques. The proposed antennas are intended at a frequency of 2.8 GHz with a substrate of FR-4 EPOXY that has a dielectric constant of 4.4.it has features like enhanced bandwidth which is one of the concerns for this project. For proposed 1*1, 1*2 and 1*3 antennas the feeding techniques used are microstrip line feeding and coaxial feeding. For feeding, inverted T shaped microstrip line feeding was used. Here full ground plane is considered for ground structure. The antennas resonating ate 2.8 GHz frequency meets the desired requirements of VSWR and return loss. The stacked antenna array with a thin slot achieves a better result than single antenna. The HFSS (High Frequency Structured Simulator) tool is utilized to evaluate the performance characteristics of the designed antenna such as Return loss, VSWR, Directivity, Gain and radiation pattern

VLSI is a stream of electronics engineering thatoccupy putting millions and billions of transistors logically together on to a single chip. VLSI circuits play a vital role in modern digitalized world. FLIP-FLOPS (FFs) are the main storage elements utilized in digital system propose, that constitutes registers, shift registers, counters etc. The current utilization of the FFs employed in a typical digital design has a great influence on its performance. This paperpresentsthe design of a SISO (Serial In Serial Out) register using LCNT(Leakage Control NMOS Transistor) based D Flip Flop. The functional verification is done in mentor graphics tool. The obtained results matching with the expected ones and the comparative analysis with the previous design techniques shows that thiswill be an effective solution for the future low power register designs

Automatic detection of vehicles data has been widely used in the area of traffic surveillance system where the efficient traffic management along with safety is the main concept. This project depicts the count of the vehicles present at that particular area of traffic using the data provided by the satellite. The satellite captures the image of the particular traffic junction. This satellite image is further processed in order to find the count of the vehicles. The image contains unwanted objects along with the vehicles. For that image, apply thresholding techniques to detect the vehicles and such that unwanted objects whose gray scale values are below the threshold level will be removed. The designed system converts the satellite captured image into gray scale image. This gray scale image is then converted into binary image. It is proposed to develop a unique algorithm for detecting the vehicles using thresholding techniques. If the intensity value is greater than the threshold value, 8-bit of value 255 is assigned else 8-bit of value 0 will be assigned. The edges of the objects present in the binary image will be obtained. Noise will be reduced using filters. The bright areas which are bounded will shows the vehicles present in the image. Boundary formation is useful for detecting the objects in the image. Using Blob detection method, the properties of the objects are depicted and using the Moore Boundary tracking algorithm the boundaries of the objects are detected. Detecting the vehicles and finding the count of the vehicles are the objectives of this project.
