Research ArticleOpen accessIn the abstractUsing PLC for Custom-design of a PID/PWM Program to Control a Heater TemperatureMohammad A.K. AliaThis is a practical approach to control a continuous-time process variable (temperature) using a discrete controller (PLC) and a custom-designed software control algorithm and hardware interface, in a closed-loop system. Unlike the conventionally known technique of transforming a digital control action into a proportional analogue one by a D/A converter followed by power amplifier, the control action was formed internally … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractLossless Compression Using LFSRsR. Muthiah, K. Neelakantan, Somi SebastianWhile lossy compression techniques are used for images, sound. where feature reproduction is more important than the actual data, it is necessary to use lossless compression for certain files containing data, programmes. Lossless compression techniques are not as effective as lossy ones and usually require a lot of computation for both compression and decompression. We presented a novel lossless compression … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,999 accessesView PDFCite
