An internal combustion engine (ICE) is an engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine the expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine. The force is applied typically to pistons, turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy.
The Cyclone Engine is built of three major components, the Steam Generator, Piston Block, and Condenser. The working fluid, deionized water, travels continuously through these three components. Beginning in the steam generator, moving into the pistons, then to the condenser, and finally pumped back into the steam generator.
This presentation covers about 'Heat Engine' precisely.Two Stroke Engine, Four Stroke Engine-Comparison, working Principle, Description of Engine Components, Cooling system, Lubricating system, Timing Diagram etc. It will be helpful for Mechanical Engineering students, so will for Electrical Engineering Students and obviously for those who want to learn about 'Engine' to meet personal thirst. Enjoy.
The vehicle propulsion is usually obtained by means of engines, also known as prime movers, i.e. mechanical devices capable to convert the chemical energy of a fuel into mechanical energy. By the way, the English term “engine”, is likely to have a French origin in the Old French word “engin” which in turns is thought to come from the Latin “ingenium” (sharing the same root of “ingénieur” or “engineer”).

It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.
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.
Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

2. HISTORY OF ICE
• JJ LENOIR (1860) PIONEER
OF IC ENGINE
• NICOLAUS OTTO &
EUGENE LANGEN(1876)
SI ENGINES
• RUDOLF DIESEL(1897)
CI ENGINES
3. INTERNAL COMBUSTION ENGINES
• The internal combustion engine is a heat engine that
converts chemical energy in a fuel into mechanical energy,
usually made available on a rotating output shaft.
• Chemical energy of the fuel is first converted to thermal
energy by means of combustion or oxidation with air inside
the engine.
• This thermal energy raises the temperature and pressure
of the gases within the engine, and the high-pressure gas
then expands against the mechanical mechanisms of the
engine.
4. INTERNAL COMBUSTION ENGINES
• This expansion is converted by the mechanical linkages of
the engine to a rotating crankshaft, which is the output of
the engine. The crankshaft, in turn, is connected to a
transmission and/or power train to transmit the rotating
mechanical energy to the desired final use.
13. Working Cycle (Strokes)
