ABSTRACT
Recent evolutionary achievements in robotics and bioengineering have given scientists and engineersâ„¢ great opportunities and challenges to serve humanity. With the development of radar and ultrasonic technologies over the past four decades, when combined with the robotic technology and bioengineering, gave rise to new series of devices, known as electronic travel aids (ETAs). It operates similar to a radar system, sends a laser or an ultrasonic beam, which after striking the object reflects ba ....etc

AGING OF BITUMEN


INTRODUCTION:
Transportation facilities are required for the economic development of a country .

Population growth and economic development result extensive development of asphalt-paved roadways

Bitumen is used for coating in pavement construction .

Bitumen serves as a satisfactory binder in improvement of physical interlocking of aggregate bitumen mixes

Its properties changes as it ages in bulk storage , transport and storage on site.

The aging of bitumen then leads to deterioration of pavement

Observations About Microwaves

Microwave ovens cook food from inside out
They can cook foods unevenly
They don’t defrost foods well
You shouldn’t put metal inside them?!
Do they make food radioactive or toxic?

INTRODUCTION
A major problem facing Planet Earth is provision of an adequate supply of clean energy. It has been that we face ...three simultaneous challenges -- population growth, resource consumption, and environmental degradation -- all converging particularly in the matter of sustainable energy supply. It is widely agreed that our current energy practices will not provide for all the world's peoples in an adequate way and still leave our Earth with a livable environment. Hence, a major task for the new century will be to dev ....etc

CHAPTER-1
What Is a Satellite?

A satellite is something that goes around and around a larger something, like the earth or another planet. Some satellites are natural, like the moon, which is a natural satellite of the earth. Other satellites are made by scientists and technologists to go around the earth and do certain jobs.
Some satellites send and receive television signals. The signal is sent from a station on the earth's surface. The satellite receives the signal and rebroadcasts it to other pl ....etc

Definition

A d.c,machine is a highly versversatile energy conversion device.In normal dc machines, stator pole is not laminated,armature core is always laminated to reduce eddy -current losses d.c.machines used in control systems These d.c machines mainly consists of two types .i.e generators & motors, In the year1821 Michael faraday invented these machines i.e.generators&motors basing on his laws of magnetic induction.

Applications

The DC generator system is designed and optimized to deliver the high currents at low voltages required ....etc

MAGNETORHEOLOGICAL FLUID DAMPER
1.INTRODUCTION
Vibration isolators or dampers are commonly used to mitigate vibrations in structures or machines. The isolators are typically passive and they are designed to reduce the vibration of the most undesired frequency. However, in many applications, the excitation frequency varies across a large range. In a semi-active device, the stiffness or damping can be adjusted during operation. Changing the stiffness of the support device can be exploited by moving the eigenfrequency o ....etc
