107 A shared memory algorithm and proof for the alternative construct in CSPCommunicating Sequential Processes (CSP) is a paradigm for communication and synchronization among distributed processes. The alternative construct is a key feature of CSP that allows nondeterministic selection of one among several possible communicants. Previous algorithms for this construct assume...Shared memory algorithm; Communicating Sequential Processes; CSP1987
108 A simple convolution procedure for calculating currents induced in the human body for exposure to electromagnetic pulsesAbstract-The finite-difference time-domain (FDTD) and frequency dependent finite difference time-domain (FD)2TD methods have been previously used to calculate internal electric (E) fields and induced currents for exposure of the anatomically based model of the human body to electromagnetic pulses (E...1994
109 A single chip low power asynchronous implementation of an FFT algorithm for space applicationsA fully asynchronous _x000C_fixed point FFT processor is introduced for low power space applications. The architecture is based on an algorithm developed by Suter and Stevens specifi_x000C_cally for a low power implementation. The novelty of this architecture lies in its high localization of compo...1998
