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 the ....etc

high speed underwater acoustic modems is shown in this paper. high speed digital communication and broadband underwater acoustics technologies have been combined to achieve this . increased data rate and decreased power consumption is achieved by Broadband Spread Spectrum Technology. The underwater communication has to deal with noises such as offshore drilling noise, ambient noise, ship noise etc. no communication errors has been seen to appear with these noises.
Broadband Spread Spectrum Technology us implemented using DSP which is sui ....etc

INTRODUCTION


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, m ....etc

The syllabus for Physics at the Higher Secondary Stage has been developed with a view that this stage of
school education is crucial and challenging as it is a transition from general science to discipline-based
curriculum. The recommendations of National Curriculum Framework-2005 have been followed, keeping
the disciplinary approach with rigour and depth, appropriate to the comprehension level of learners. Due
care has been taken that the syllabus is not heavy and at the same time it is comparable to the international
standards. The sylla ....etc
