Simulation of Locomotive Control of Traction Motor Using a New Bidirectional ...paperpublications3
Abstract: This project mainly concentrates on a simulation of locomotive control of traction motors with a new bidirectional DC-DC-AC converter using Renewable Energy Sources. The existing system is developed with four quadrant operation of dc series motor or induction motor fed voltage and frequency control using power electronic controllers. But in this system the efficiency is low and speed control is not synchronized with other motors. Therefore there is jerking of compartments, uniform braking is not possible in the traction system. The DC motors have been utilized for traction for over one hundred years and were originally chosen because of their inherent compatibility with traction power supplies and ease of mounting within locomotive bogies. The proposed system is designed with fuel cell based bidirectional DC-DC-AC dual inverter for traction motor to optimize third harmonic distortion, switching pattern losses, voltage fluctuations, reducing of switches, cost and also increasing efficiency and feasible operation of traction motors. The Fuel cell based system is powered to the traction motor to run forward, reverse and regenerative braking operation with the help of bidirectional control. So that the kinematic operation of traction motor is control the voltage, speed, torque levels using the ZVS DC-DC-AC converters. The proposed multilevel inverter minimizes the THD with the implementation of Z-source inverter. It is useful in boosting the voltage and additionally reducing the voltage fluctuations in the nine switch Z-source inverter. In a fuel cell powered to traction system the bidirectional dc-dc converter and inverter are essential for efficient performance of the traction motor. The simulation of dual converters is developed using MATLAB/SIMULINK and rotor current, stator current, stator voltage, rotor speed, electromagnetic torque and rotor angle is obtained for the traction motor. The multilevel inverters are developed to reduce the total third harmonic distortions (THD) in the converters. The multilevel converters are used to reduce the switching pattern losses. The performance of the traction system is compatible and running of motors is continuous without any disturbances. The most advantageous of the system is the multistep boost ZVS converter is implemented to maintain the constant power output.

Effect of beam current, weld speed and dissolution on mechnical and microstru...eSAT Journals
Abstract Electron beam welding has proved phenomenal in welding of components used in space because it uses a vacuum environment which eliminates substances like oxygen, nitrogen, and hydrogen. The main advantage of EBW is its ability to weld dissimilar materials and incorporate desirable properties in the assembly. It has high depth to width ratio and focuses exactly on the portion to be welded, thereby reducing the weld area, making it one of the most suitable welding processes. In this study, welding has been done on a circular heterogeneous component using an electron beam welding machine to determine the effect of beam current, speed of weld and dissolution on the bead geometry, hardness at the weld bead and the heat affected zone. This component is made up of AISI 304(Austenitic) and AISI 446 (Ferrite) stainless steel, both of which are widely used in space applications.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
