Continuously variable transmission (CVT) (PPT Notes)

Definition

After more than a century of research and development, the internal combustion (IC) engine is nearing both perfection and obsolescence: engineers continue to explore the outer limits of IC efficiency and performance, but advancements in fuel economy and emissions have effectively stalled. While many IC vehicles meet Low Emissions Vehicle standards, these will give way to new, stricter government regulations in the very near future. With limited room for improvement, automobile manufacturers have begun full-scale development of alternative power vehicles. Still, manufacturers are loath to scrap a century of development and billions or possibly even trillions of dollars in IC infrastructure, especially for technologies with no history of commercial success. Thus, the ideal interim solution is to further optimize the overall efficiency of IC vehicles.

Design, Analysis, Fabrication And Testing Of A Composite Leaf Spring (PPT Notes)

Definition

In order to conserve natural resources and economize energy, weight reduction has been the main focus of automobile manufacturers in the present scenario. Weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The suspension leaf spring is one of the potential items for weight reduction in automobiles as it accounts for 10% - 20% of the unsprung weight. This achieves the vehicle with more fuel efficiency and improved riding qualities.

Global Issues

Everyday radios, newspapers, televisions and the internet warn us of energy exhaustion, atmospheric pollution and hostile climatic conditions. After few hundred years of industrial development, we are facing these global problems while at the same time we maintain a high standard of living. The most important problem we are faced with is whether we should continue "developing" or "die".

Hydro Drive (PPT Notes)

Definition

Hydro Forming uses water pressure to form complex shapes from sheet or tube material. The pressure may go up about 60,000 psi depending on the component.

As the automobile industry strives to make car lighter, stronger and more fuel efficient, it will continue to drive hydro forming applications. Some automobile parts such as structural chassis, instrument panel beam, engine cradles and radiator closures are becoming standard hydro formed parts.

Head And Neck Support (HANS) (PPT Notes)

Definition

Only recently has the racing industry acknowledged that the number one cause of racing-related fatalities is basilar skull fractures from excessive head motions and neck loading. Racing legend Dale Earnhardt's death proved to the racing world and the general public that what appears to be a low impact crash can be fatal. Under development and extensively tested for over a decade, there is a device that can reduce the risk of serious injury or even death to the driver in such a crash. It is the Head And Neck Support (HANS) device.

Fractal Robots (PPT Notes)

Definition
In order to respond to rapidly changing environment and market, it is imperative to have such capabilities as flexibility, adaptability, reusability, etc. for the manufacturing system. The fractal manufacturing system is one of the new manufacturing paradigms for this purpose. A basic component of fractal manufacturing system, called a basic fractal unit (BFU), consists of five functional modules such as an observer, an analyzer, an organizer, a resolver, and a reporter. Each module autonomously cooperates and negotiates with others while processing its jobs by using the agent technology. The resulting architecture has a high degree of self-similarity, one of the main characteristics of the fractal. What this actually means in this case is something that when you look at a part of it, it is similar to the whole object.

Military Radars (PPT Notes)

RADAR (Radio Detection and Ranging) is basically a means of gathering information about distant objects by transmitting electromagnetic waves at them and analyzing the echoes. Radar has been employed on the ground, in air, on the sea and in space. Radar finds a number of applications such as in airport traffic control, military purposes, coastal navigation, meteorology and mapping etc.

Smart Bombs (PPT Notes)

Introduction

Smart bombs are weapons capable of destroying enemy targets with out the need for a launch aircraft to penetrate the envelops of the air defense systems. These essentially comprise a terminal guidance unit that guides them in the last phase to achieve pinpoint accuracy. Increased accuracy means that a single, moderate-size bomb can give a better result than multiple strikes with larger, non-guided bombs.

Handfree Driving (PPT Notes)

Definition
All of us would like to drive our car with a mobile held in one hand, talking to the other person. But we should be careful; we don't know when the car just before us apply the break and everything are gone. A serious problem encountered in most of the cities, National Highways, where any mistake means no 'turning back'! There comes the tomorrows technology; Hand free driven car. Initializing the modern technological approach in Robotics.
What is the need for safety precaution?

Logo Package Drawing Using C (CODE)

This is a logo package by which you can draw different object using
keyboard. This program uses number of colour patterns and object movement
at the time drawing. This logo manages the cicle by which you can move into
different directions. Also can increase or decrease the radious of the circle
as you wish.
Code is given below.

Bricks "computer game" In C (CODE)

Bricks is a computer game which is played by the single player at a time. In this game a four layer of
bricks is there and you have to knock out the brick by the ball to get the point.For each knock you get 5 points.
You have maximum of four balls and each time you lose the ball 10 marks are deducted from your score.
You have to catch the ball on the paddle which is appearing on the bottom on the screen and if you will not able the catch the ball on the paddle you lose the ball. For moving the paddle use left and right arrow key.
As the ball and paddle are to be moved throughtout the game, we first store their images
in the memory using malloc() function which is used to allocate the memory.After this , the image at new coordinates is set erasing the previous location. When the ball reaches to the boundary it will pushed inside.

Major Project In C (CODE)

In this project the main menu provide the option for different
 demonstration. The item from the main menu can be selected by using the enter key or by pressing the
    hotkey which is represented by the bold character. The getoutput() function
    manage the movement of the cursor and selection of the menu item this function
    also use getkey() function to to find which key has been press by the user.
    The Showmenu() function is used to displays the menu in box drawn by menubox()
    available in the "intro.h".
