Renewable and non-renewable energy resources

A.   Renewable Energy Sources :  These are the source of energy which are inexhaustible i.e., can be used the produce energy again  and again. Example : Sun. Water. Animal dunk. etc.

a. Solar Energy : Solar energy is a clean, cheap and abundantly available renewable energy and it also that most important of the non-conventional source of energy because it is non-polluting and, therefore help in decreasing the green house effect.
b. Biogas : 

1. Biogas is formed due to the decomposition of organic waste matter.
2. During the decomposition of organic matter the gases, such as carbon dioxide, hydrogen and hydrogen sulphide are formed.
3. the organic waste is generally animal dunk, plant waste etc.

c.  Hydro Energy :  

1. it is renewable energy source, which is used to generate electricity.
2. hydro power is obtained from water flow falling water from a height.
3. Water store behind dam and at height has lot of potential energy which is converted into mechanical and electrical energy.

d. Wind Energy : Wind energy is a renewable energy of non-polluting energy and it has tremendous potential which if harnessed, can easily satisfy the energy demand of a country.

e. Tidal Energy : 

1. Gravitational pull by sun and moon result in the tides.
2. This type of energy can be harnessed by constructing the tidal barrage.
3. energy can be harnessed from high as well as from low tides.

B. Non-renewable energy resources :  These are the sources of energy which are exhaustible i.e., cannot be replaced if once they are used.

Example: coal,petroleum products, natural gas etc.

a. coal energy : 

1. coal is a conventional energy sources 
2. it is prepared by carbonisation of coal.
3. it is composition of mainly carbon and hydrocarbons.

b. Natural Gas : 

1. it is a one of the fossil fuels.
2. Natural gas is the cleanest fossil fuel.
3. it is mainly composed of methane with small amount of propane and ethane.

what is robot

What is a Robot?

•   Robot today are being in a wide variety of industrial application. The most majority of industrial robots  are mechanical arms attached to a fixed base, with the some form programmable control for automatic execution of motion. There are a variety of definition of an industrial robot, two of which are as follows:
• A: Robot is a re programmable multi-function manipulator designed to move material part, tool or devices, through variable programmed motion for the performance of a variety of task.(Robotic Institute of America, 1979)
• (British Robot Association ) Robotics is the engineering science and technology of robot, and their design, manufacture, application, and structural disposition. it requires a working knowledge of electronics, mechanics, and softwere.
• Law of Robotics are a set of law rule or principal, which are intended as a fundamental framework the behavior of robots designed to have a degree of autonomy.
• 3 law of the Robot.

1. Robot must not injure humans 
2. Robot must obey order 
3. Robot must protect their own existence in detailed.

Graphical kernel system

The Graphical kernal System (GKS)  was the first ISO standard for low-level computer graphics.international standard was circulated for review in september 1983.final ratification of the standard was achieved in 1985

OR

(GKS) Graphical kernal system : It is  ANSI and ISO standard. It is device independing, Host system independent and application independent. It sopport both tow-dimentional and three-dimentional data viewing.

1. GKS. is defined in term of a number of levels discribing the level of support in term of facilities.
