USE OF SOLAR POWER IN REFRIGERATION SYSTEM
The power incident from the sun to the earth has very much amount of energy that the present consumption rate of all the commercial and general uses. We utilize only 0.1% of total incident sun energy on the surface of earth. Thus solar energy can fulfill our present as well as future needs of energy. That is a reason it called renewable sources of energy. It is also environmental clean source of energy and available at whole part of world where people live. Using of solar energy in the field of refrigeration and air conditioning system it become very economical.
In our project we provide solar heat in generator for heating purpose of vapor compression refrigeration system.
For past few decades, energy has played a prominent role in the development of technology and economy. Energy has now become inevitable factor for production as well. The objective of this project is to develop an environment friendly vapour absorption system. Vapour absorption system uses heat energy, instead of mechanical energy as in vapour compression system, in order to change the condition of refrigerant required for the operation of the cycle. R 717(NH3) and water are used as working fluids in this system. The basic idea of this project is derived from the solar heating panel to obtain heat energy, instead of using any conventional source of heat energy. In this project various observations are done by varying operating conditions related to heat source, condenser, absorber and evaporator temperatures. The drawback of this system is that, it remains idle in the cloudy weather conditions.

Thermal Power Plant - Full Detail About Plant and Parts (Also Contain Animate...Shubham Thakur
A thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different fossil fuel resources generally used to heat the water. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy.[1] Certain thermal power plants also are designed to produce heat energy for industrial purposes of district heating, or desalination of water, in addition to generating electrical power. Globally, fossil fueled thermal power plants produce a large part of man-made CO2 emissions to the atmosphere, and efforts to reduce these are varied and widespread.

Generation of Air Conditioning by using Exhaust Gases and Cooling Water of an...ijtsrd
Air conditioning system of car or buses works on principle of vapor absorption cycle of refrigeration VAR . This system reduces the fuel economy of fuel of vehicle. When vehicle moving with air conditioning, it consumes more amount of fuel than vehicle rubs without AC, typically, it consumes 15 to 20 more amount of fuel. Exhaust gases coming from engine of vehicle have temperature ranges to 300 to 400 degree centigrade at full load it carries 25 to 30 of heat supplied by fuel. For A.C. of an automobile, the heat of exhaust gases is utilized to run vapor absorption refrigeration cycle instead of vapour compression refrigeration system. Resulting, it improves fuel economy of A. C. heavy vehicle. In this project try to integrate the vapor absorption refrigeration system with car or bus or heavy vehicle engine exhaust. Comparative study has been carried out when car running with VCR and vapor absorption system of refrigeration. Dr. M.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

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.
