Real time systems are at the heart of industrial automation applications and thus, a time response mechanism is required to be able to implement such systems. This paper presents a survey of implementing real time systems for industrial automation applications. Recently, PLCs have dominated industrial automation implementations but however, they do present some challenges especially ...

The band gap for 2D PhC with different modes and different lattice structures using FDTD has been computed. Three PBGs between the first and the second bands, between the second and the third bands and between the fourth and fifth bands are concluded. Simulation results shows that for band structure computation is of 1D PhC ...

People have seen over the years that the process of manual attendance has been carried out across almost all educational institutions. The process is not only time consuming but also sometimes inefficient resulting in the false marking of attendance. Today, people need not maintain pen and paper based attendance registers. Following this thought, the authors ...
