230 A scheduling strategy for shared memory multiprocessorsAn efficient scheduling strategy for shared memory multiprocessors is described. The rapid dissemination of tasks to available procesors and ready queues is crucial to the performance of any parallel system. Such overheads determine the attainable speedup and performance of the system. Poor techniq...Shared memory multiprocessors1990
231 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
232 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
233 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
234 A stability condition for certain bilinear systemsAbstract-This correspondence derives a simple sufficient condition for the output of a discrete-time, time-invariant bilinear system to be bounded whenever the input signal to the system is bounded by a finite constant.1994
235 A stability result for RLS adaptive bilinear filtersAbstract- This letter considers recursive least squares (RLS) adaptive nonlinear filtering using bilinear system models. It is shown that the extended RLS adaptive bilinear filter, as well as the equation-error RLS adaptive bilinear filter, are guaranteed to be stable in the sense that the time aver...1994

238 A standard magnetic tape format for digital image exchangeThis proposal describes a simple yet flexible magnetic tape format for exchanging digital image information. Multi-dimensional arrays of raster scan data are stored as sequential files, with descriptive information related to the sefiles stored in an initial directory file. Directory information is ...Raster scan data1981
239 A standard-cell self-timed multiplier for energy and area critical synchronous systemsThis paper describes the design of a standard-cell self-timed multiplier for use in energy and area critical synchronous systems. The area of this multiplier is bounded by N rather than N2 as seen in more traditional combinational parallel array designs, where N is the word size. Energy has a polyn...2001
240 A stochastic FDTD method for statistically varying biological tissuesTHE analysis of radio wave absorption is a continuing concern for the cell phone industry due to health effects (and associated regulations) of the person using the cell phone [1,2].

243 A stratospheric connection to Atlantic climate variabilityIt is well recognized that the stratosphere is connected to tropospheric weather and climate. In particular, extreme stratospheric circulation events and their dynamical feedback on the troposphere are known to play a major role1. However, what is not known to date is whether the state of the strat...2012-01-01
244 A structural MRI study of human brain development from birth to two yearsBrain development in the first 2 years after birth is extremely dynamic and likely plays an important role in neurodevelopmental disorders, including autism and schizophrenia. Knowledge regarding this period is currently quite limited. We studied structural brain development in healthy subjects from...2008-01-01
245 A study of Pierce's group generatorPierce describes an approach to map learning with uninterpreted sensors and effectors.
