Abstract

In medical sciences and particular in cardiology related area, ECG machine is considered a basic equipment to get the fundamental knowledge about proper functioning of heart. In this work the aim is to make energy efficient ECG machine design on FPGA using capacitance scaling technique while the device is operating under various WLAN specific frequencies. Concept of internet of things is used in this work by adding additional 128-bit IPv6 address in the input of ECG machine that will use to control the device via internet. Kintex-7 is used from the FPGA family for this task. It is analyzed that 89.15%, 89.75% and 89.81% power reduction can be achieved under device operating frequencies 0.9 GHz, 2.4 GHz and 3.6 GHz respectively when the capacitance is taken 500 pF in place of 5000 pF.

Abstract

Objectives: In the innovation of current data correspondences, the requirement for data well being emerges to make the execution time and calculation overhead less connected with the execution of cryptographic calculations increments correspondingly. Method/Analysis: Parallelizing the calculation of cryptographic calculations on numerous center processing frameworks might be a promising technique to diminish the execution time and at some point or another, the quality admission of such calculations. In this paper, we build a pipelined form to look into and assess the execution time and quality admission of the Blowfish cryptographic calculation on the Single-Chip Cloud PC (SCC), a trial processor made by method for Intel Labs. Findings: On this model the Blowfish cryptographic calculation is isolated to littler lumps and each nibble is managed handiest by method for one center. The use of message passing interface, the info actualities goes thus through the majority of the centers stressed. In view of the verbal trade overhead and idleness connected with this model, we tested and analyzed the highest point of the line message length to go among the centers to abstain from soaking the on-chip dispatch group. Improvement: Our outcomes show that our parallel system is 27X speedier than the successive approach and yields near 16X less quality admission on the SCC stage.

Abstract

Nowadays digital media manipulation has become a common trend. Digital media, especially images, being one of the primary modes of communication, can be easily manipulated. Current research trends in digital image forensics focus on validating the authenticity of the image. Objectives: Objective of the present study is to authenticate objects in an image using light sources and their properties. Method: By locating the direction of the light source, forgery in the images can be easily detected. Inconsistencies between different light sources in the image highlight image tampering. This paper focuses on detection of image forgery using lighting inconsistencies. The proposed technique measures the lighting properties from different objects or surfaces present in the image. Finding: The model for digital forensics identifies the lighting discrepancies in the objects of an image and provides results indicating difference between real and fake images. Improvement: The proposed technique is an objective based method and identifies digital image forgery based on physics of the environment. Results are promising and reproducible making the technique an important tool for image forgery detection.

Abstract

Objectives: To highlight the barriers to the effective usage of biopesticides and solutions to these barriers for biopesticides produced from fungi Trichoderma viride and Beauveria bassiana. Methods and Statistical Analysis: Recent paper in last decade on production techniques and method of biopesticides from environmental friendly fungi namely T. viride and B. bassiana have been reviewed and analyzed. Findings: Optimized conditions of temperature and pressure can maintain the pH at about 7 which will result in an enhancement in the shelf life of the biopesticides from 2-3 months to about 1 or 1.5 years. Effective selection of carrier can benefit in the stability of the biopesticides characteristics and also decrease the cost of the products. The usage of metabolites and additives can highly affect the performance of the bio products and can increase their potential. Application/Improvements: Active packaging could greatly enhance/increase the shelf life of the biopesticides and thereby making them viable alternative cheap ecofriendly biopesticides for organic farming.

Abstract

Objectives: To increase the corrosion resistant property of C60 steel so that it can sustain high temperature corrosion at high temperature applications. Methods: The Friction Stir Processing (FSP) was done on C60 steel with tungsten carbide tool under three different rotational speeds 200 rpm, 400 rpm, 600 rpm, feed rate of 40 mm/min with plunge depth of 1 mm. Findings: The behavior of Friction Stir Processed (FSP) C60 steel for hot corrosion was studied in the salt environment at 900°C for 50 cycles; every cycle consisted of heating at 900°C for 1 hour followed by 20 min of cooling in air at room temperature. The weight change per unit area was reported after each cycle for bare and friction stir processed samples, to access the corrosion kinetics. EBSD, SEM/EDS, optical microscopy analyses techniques were used to characterize corroded samples. Improvements: FSPed samples were found to offer high corrosion resistance to bare steel; this may be due to presence of dense protective scale as a result of refined grains. The process can be used for various applications of automobiles and for material surface treatment.
