Abstract
Adaptive optics is a new technology which is being used now a days in ground based telescopes to remove atmospheric tremor and thus provide a clearer and brighter view of stars seen through ground based telescopes. Without using this system, the images obtained through telescopes on earth are seen to be blurred, which is caused by the turbulent mixing of air at different temperatures.
Adaptive optics in effect removes this atmospheric tremor. It brings together the latest in computers, material scie ....etc

ABSTRACT
FIBRE-OPTICS COMMUNICATION
Most reference materials that discuss the historical perspective mention about Indian smoke signals. None of these primitive systems was secure due to the spreading of the unguided light. Ideally, a communication system should be secure and should not require installation of a cumbersome physical media. Fiber optics satisfied these desires, and as early as 1958, fiber-optic equipment was being focused for use in the factory. The ....etc

This article presents a fiber-optics-based sensing network for fault detection in power systems. This scheme is considered secure and immune from interferences. A passive rugged fiber-Bragg-grating-based sensors are present a each of the monitoring locations. magnetostrictive transducers are used in the place of CT or PT for the purpose of converting the magnetically induced currents into optical signals. The temperature drift in these sensors can be easily compensated for. An increased fault current at a certain location causes a surge in th ....etc

Role & Role Effectiveness
Role, Role Space & Role Set
• Mutual obligations under a social system
• Functions one performs in response to the expectations
• Role is defined with the expectations of the role senders, including those of the role occupant.
• Role Space is a dynamic relationship between the self and the various roles an individual occupies and also amongst these roles
• Role Set is a subsystem or inter relationships between a particular role and the other roles in an organi ....etc

SEMINAR REPORT ON FIBER OPTICS BASED COMPUTER NETWORK
INTRODUCTION
In recent years it has become apparent that fiber-optics are steadily replacing copper wire as an appropriate means of communication signal transmission. They span the long distances between local phone systems as well as providing the backbone for many network systems. Other system users include cable television services, university campuses, office buildings, industrial plants, and electric utility companies.
