A Real-time Algorithm for Atmospheric Turbulence Correction

Atmospheric turbulence poses a significant problem in fields like long range surveillance and astronomy. This paper presents an algorithm for correcting atmospheric turbulence. This algorithm is capable of giving real-time performance, processing a 640×480 resolution frame at more than 30 FPS. This algorithm is useful in restoring videos from fixed cameras and videos having negligible background changes w.r.t foreground… Download

Heat Transfer & Flow Simulation in PCB

The loss of heat from the surface of a PCB to the ambient air is difficult to compute as many process happen at the same time. This situation is much more challenging to describe mathematically since it involves the simultaneous processes of heat spreading by conduction and heat extraction over the surface of the board by convection and radiation. The…

Digital Signaling and Their Inter-conversion

Nowadays we face many ICs which have different interfaces like LVPECL, LVDS, CML, LVCMOS, TTL, HSTL etc. While designing a PCB schematic, interfacing of one IC with another IC with different signalling supported, becomes a hurdle to desgin the circuit. In this case a desginer always look for an ASIC which can act as a bridge between two signalling…… Download
