    Title: Design and Implementation of Flash ADC Using Precise Comparator

    Authors: R Sindhu

    Abstract: A low-power comparator is presented. PMOS transistors are used at the input of the preamplifier of the comparator as well as the latch stage. Both stages are controlled by a special local clock generator. At the evaluation phase, the latch is activated with a delay to achieve enough pre amplification gain and avoid excess power consumption. Meanwhile, small cross coupled transistors increase the preamplifier gain and decrease the input common mode of the latch to strongly turn on the PMOS transistors (at the latch input) and reduce the delay. Unlike the conventional comparator, the proposed structure let us set the optimum delay for pre amplification and avoid excess power consumption. The speed and the power benefits of the comparator were improved. A Flash ADC is designed using this proposed comparator. Flash ADC is the fastest among the entire analog to digital converters. The designed flash ADC can achieve high speed and low power consumption.

    Title: The Calculation of Antennas’ Separation for the Optimum Operation of the Space Diversity Reception System of Different Point-to-Point High Frequency Installations in Libya

    Authors: Mohamed Youssef Ahmed Abou-Hussein

    Abstract: The space diversity reception system is the commonest used type of the diversity reception systems. It is used as a receiving terminal to overcome the fading phenomenon depending upon its receiving antennas separation amounts, in various point-to-point High Frequency (HF) installations, which are using operating HFs ranging from 2 To 30 Megahertz (MHz). The aim of this research is to experimentally calculate the antennas separation as times of the transmitting HF signal wave length (λ), and its equivalent in kilometer (km) for the used optimum operation of the space diversity reception system in Libya. Methodology: The λ measurements are calculated as a function of each different path lengths (0,500,1000, and 1500 Km), and its λ of arbitrary operating HF, and for its equivalent amounts in Km are computed as a function of each mentioned different specific path lengths, and its λ of operating HF that is equal the average values (mean is figured for two median values) that are ascertained for two point-to-point path FOT bands which are calculated practically in Libya, one of them for the winter (December, January, and February), and another one for the summer ( June, July, And August) seasons, by using the Central Radio Propagation Laboratory (CRPL) method of ionospheric prediction of the National Bureau of Standards (NBS) in U.S.A. The results show that the antennas separation amounts are obtained as times of λ which are ranging from 17λto 159 λ, and its equivalent, the more applicable results, in Km which are ranging from 0.4 to 15.4 Km. The conclusion: the results in Km can be implemented practically as one of the most important factors of the space diversity reception system good design, which is related for the overall reception performance improvement of the different point-to-point HF installations in Libya.

    Title: LTD2 vehicle driving System

    Authors: Dr. T. Muni Reddy and Dr. A. Pulla Reddy

    Abstract: In this paper we provide vehicle driving system based on LTD2 (Listen, Topology Distance-two- protocol and Distributed System) provides anti-collision system for vehicle driving. Which always listen the position of other vehicle by V2V and maintain the minimum distance between the vehicles. V2V exchange information like VID (vehicle ID), Status (Normal, Emergency and VIP) and Category (Public, Private and Personal). LTD² also calculates the distance between the vehicles. This system follows Distance-two- protocol during overtaking and also follows mesh topology with minimum distance. Distributed system allows route clearance for emergency and VIP vehicles by passing their decision to other vehicles which are in and around the emergency vehicle.

    Title: Analysis of Lung Cancer Detection and techniques Finite Element Method

    Authors: Sonia and Rajender Kumar

    Abstract: Threats recognition is usually completed correctly with expert techniques and procedures set was basically helping in the stage of proof recognized by the dominant, also incorporate a way entirely bleak and very dependent on the particular individual. It presents a high possibility of human slip-up in recognition engine that requires electronic means. Further, this paper focuses on the area’s most early malignancy through automated procedures for mix-ups reduce human and make proper progressive structure and trouble free. In the proposed work, take care of the calculation and false picture frame nerves have to plan a modern technique for the initial ID title lung most threatening development. These days, photographs dealing with the system can be uncontrollable used in the field of intelligent different image enhancement aid in early recognition and assessment of the stage of treatment, the part time let alone expect the job very pivtol in running more diverse than the standard in sneak the ultimate goal Like most malignancies lung, breast disease, etc. The investigation focuses on exceptional photo and precision. outstanding appraisal picture as the progress of the update is sorted out at the level where the philosophy is ready for pre-lower hinge used on the channel Gabor Gaussian rules; from the time division performed above considerations revamped area of the image and commitment to the extraction of a trademark is obtained, in addition to depending on the general limits, evaluation ordinariness made .Inside is happening with the distinguished capacity assessment is important for proper relations image pixel per cent and ensure naming , In this assessment has been made the subject of a class of nerves resulting framework is more remarkable than any other procedure today’s classrooms.

    Title: Radiation Hardened SRAM Design for Efficient Space Applications with Adiabatic Logic

    Authors: Mrs .K.Swapna

    Abstract: 9T adiabatic SRAM structure was presented for efficient space applications. The proposed SRAM uses a nmos switch to reduce the power consumption mainly the leakage power and delay of SRAM design. Our simulation results show that while the energy dissipation area and delay of the proposed circuit is improved over that of existing method.
