Abstract Energy efficiency in public buildings is a prime issue of research. We have studied the basic principles and implementation of energy efficiency in public buildings in this work. To do so, we have basically developed an algorithm with a sound architecture. The system implementation results are presented briefly.... Read More

Abstract In the work we have assessed the mean channel capacity of selection combination of diversity system based on signal decision algorithm. The system is implemented in the microcell interference environment. We have experimented it with the results that shown the effects of channel system indicators. We have received the mean channel capacity based on signal decision algorithm that has the... Read More


Optisystem, an Optical Fibre in Linear Regime

Abstract We have developed a package called as Optisystem which is an optical fibre in linear regime. We have studied the Gaussian pulse propagation with fibre with group velocity. The results shown the Gaussian pulse shapes in the characteristic section with velocity dispersion. Further we have presented the velocity dispersion and dispersion induced chirp with results....
