202 Watkins, Gary ScottA real time visible surface algorithmWith the increasing use of computer graphics, a need is growing for a processor capable of displaying solid objects. Environmental simulation and architectural modeling are only two areas that would benefit from such a diplay processor. This dissertation describes an algorithm designed for such a ...Surface algorithm1970
203 Hawkes, KristenA reappraisal of grandmothering and natural selectionKachel et al. [1] conclude from simulations of their agent-based model that fitness benefits from helpful grandmothers do not select for increased longevity. We studied their assumptions and model, ran further simulations and found flaws that are fatal to their test. Here, we explain four problems a...2011-01-01
204 Brown, Francis HaroldA reappraisal of the geomagnetic polarity time scale to 4 MA using data from the turkana basin, East AfricaRecalibration of the Pliocene and early Pleistocene geomagnetic time scale using the K-Ar dated fluvial sequence of the Turkana Basin in East Africa agrees with calibrations based on astronomical calculations. Ages estimated here are: Olduvai Subchron, 1.78-1.96 Ma; Reunion Subchrons, 2.11-2.15 Ma ...2012
205 Fogel, Alan DaleA relational perspective on the development of self and emotionBegin with two premises. First, psychological experience always implies a connection, a relationship: with another person, with cultural tools or language, or with the natural environment. Life is a network of relationships. Second, psychological experience is always dynamic and changing. The sim...2001
206 Fogel, Alan DaleA relational perspective on the development of self and emotionThis work was funded in part by a grant to the author from the United States National Institute of Mental Health (MH48680 and MH57669). I am grateful to the following individuals for their comments on this chapter: Kari Applegate, Trevor Burnsed, Jacqueline Fogel, J'lene George, Ilse de Koeijer, ...2001
207 Myntti, JeremyA review of "Introduction to indexing and abstracting" by Donald B. Cleveland and Ana D. ClevelandIntroduction to Indexing and Abstracting by Donald and Ana Cleveland has been used in Library and; Information Science classrooms for many years. The latest edition of this text has been updated to; include more information about the current indexing environment where many people seem to favor; onli...Indexing; Abstracting2014
208 Crespo, Jose GuillermoA review of chemosensation and related behavior in aquatic insectsInsects that are secondarily adapted to aquatic environments are able to sense odors from a diverse array of sources. The antenna of these insects, as in all insects, is the main chemosensory structure and its input to the brain allows for integration of sensory information that ultimately ends in b...2011-09-13
209 Simpson, Jamesina J.A review of progress in FDTD Maxwell's equations modeling of impulsive subionospheric propagation below 300 kHzWave propagation at the bottom of the electromagnetic spectrum (below300 kHz) in the Earth-ionosphere waveguide system has been an interesting and important area of investigation for the last four decades. Such wave propagation is characterized by complex phenomena involving nonhomogeneous and aniso...2007-01-01
210 Podlog, Leslie WilliamA review of return to sport concerns following injury rehabilitation: practitioner strategies for enhancing recovery outcomesObjectives: Evidence suggests that competitive athletes returning to sport following injury rehabilitation may experience a range of psychosocial concerns. The purpose of this paper is to review some of the psychosocial stresses common among returning athletes and to provide practitioner strategies ...2011-01-01
211 Lawton, Evert C.A review of shear stress sign convention in interpreting Mohrs circleThe pole of planes method is a popular technique for interpreting Mohr's circle to determine the stresses (normal and shear) on planes of differing rotations in 2-D space. A survey of undergraduate textbooks on soil mechanics shows differing viewpoints on the sign convention for interpreting the she...2012-01-01
212 Kirby, Robert MichaelA scalable, efficient scheme for evaluation of stencil computations over unstructured meshesStencil computations are a common class of operations that appear in many computational scientific and engineering applications. Stencil computations often benefit from compile-time analysis, exploiting data-locality, and parallelism. Post-processing of discontinuous Galerkin (dG) simulation solutio...2013-01-01
213 George, LalA 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

215 Fujimoto, Richard M.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
216 Furse, Cynthia M.; Gandhi, Om P.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
217 Stevens, KennethA 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
