This paper proposes a performance comparison of 64-bit KASUMI block cipher architectures based on speed vs. area trade-offs. The analysis includes 8-rounds KASUMI architectures for high-speed designs, 2-rounds / 1-round KASUMI architecture for moderate area / throughput values and optimized one round KASUMI having one FI function for low area design requirements. A throughput value as high as 13.6...
This paper describes the welding process of automatic butt-fusion welding machine for polyethylene pipe in detail. A control system based on ARM processor is designed, whose hardware and software are analyzed in detail. Bang-bang and fuzzy-PID control algorithm is applied to its temperature control which improves its capacity of anti-interference. Taking ISO11414 standard as reference, the method...
With the advancement of technology and incorporation of sophisticated systems in the aircrafts, the modern aircrafts are highly dependent on the reliable electrical power systems. Prognostic and Health Management (PHM) is the evolving field for fault diagnosis, failure prevention and cost cutting maintenance. In this paper, a real-time frequency estimation algorithm based on 3-line Discrete Fourier...
Multipath is the main source of error in satellite positioning. Although various multipath reduction and delay estimation techniques have been developed, short-delay multipath is still a problem area particularly for high precision applications, indoor use and under dense urban environments. The number of close-in secondary paths is not only high in indoor and urban areas but also dynamic in nature...
