Jr.An annotated key to the nymphs of the families and subfamilies of mayfliesAttempts to provide keys to the families and subfamilies of Ephemeroptera nymphs in general entomology textbooks (i.e. Essig (1942), Chu (1949), and Brues, Melander and Carpenter (1954)) have been far from satisfactory. This difficulty exists largely because of the failure of specialists of the Ephe...1963-06
485 Greenfield, HarveyAn application of computer graphics: two concurrent investigations within the medical fieldThe aim of this project is to apply new or recently developed computer graphic techniques to a particular discipline with the thought of broadening its research capabilities. The discipline chosen, that of medicine, has emphasis places on the area of hemodynamics. It is seen that computer graphics m...Computer graphic techniques1971
486 Keller, Robert M.An approach to determinacy proofsIt is known that any parallel program graph composed of continuous operators itself represents a continuous function. In other words, the network is determinate in the sense that for a given input, the output is unique, independent of the timing of the constituent operators. This result is applied t...Parallel program graph; Determinacy proofs1978

488 Henderson, Thomas C.An approach to three-dimensional scene databasesCurrent image database research is concerned for the most part with the encoding and processing of two-dimensional images. However, the most successful approach to computer vision is based on 3-dimensional information, organized as either stacks of 2-D images (e.g., the intrinsic images of Barrow an...Image databases; Three-dimensional; Scene databases1987
489 Keller, Robert M.; Lindstrom, Gary E.An architecture for a loosely-coupled parallel processorAn architecture for a large (e. g. 1000 processor) parallel computer is presented. The processors are loosely-coupled, in the sense that communication among them is fully asynchronous, and each processor is generally not unduly delayed by any immediate need for specific data values. The network supp...Loosely-coupled; Parallel processors1978
490 Myers, Chris J.An asynchronous implementations of the MAXLIST algorithmABSTRACT We present an efficient asynchronous VLSI architecture for calculating running maximum or minimum values over a sliding window. Running maximums or minimums are very useful for many signal and image processing tasks. Our architecture performs the calculation using the MAXLIST algorithm. In...1997

493 Bruderlin, BeatAn axiomatic approach for solving geometric problems symbolicallyThis paper describes a new approach for solving geometric constraint problems and problems in geometry theorem proving. We developed a rewrite-rule mechanism operating on geometric predicates. Termination and completeness of the problem solving algorithm can be obtained through well foundedness and ...Geometric constraint problems; Geometry theorem proving; Knuth-Bendix completion algorithm1990
494 Simpson, Jamesina J.An E-J collocated 3-D FDTD model of electromagnetic wave propagation in magnetized cold plasmaA new three-dimensional finite-difference time-domain (FDTD) numerical model is proposed herein to simulate electromagnetic wave propagation in an anisotropic magnetized cold plasma medium. Plasma effects contributed by electrons, positive, and negative ions are considered in this model. The current...2010-01-01
495 Marcus, RobinAn eccentrically biased rehabilitation program early after TKA surgeryRehabilitation services are less-studied aspects of the management following total knee arthroplasty (TKA) despite long-term suboptimal physical functioning and chronic deficits in muscle function. This paper describes the preliminary findings of a six-week (12 session) eccentrically-biased rehabili...2011
496 Mathews, V. JohnAn efficient algorithm for joint estimation of differential time delays and frequency offsetsABSTRACT This paper introduces an efficient algorithm that jointly estimates differential time delays and frequency offsets between two signals. The approach is a two-step procedure. First, the differential frequency offsets are estimated from measurement of the autocorrelation functions of the rec...1992
497 Mathews, V. JohnAn efficient algorithm for lattice filter/predictorABSTRACT An efficient method for updating the lattice filter/predictor coefficients using the sign algorithm is introduced. The pertinent coefficients are updated using only the signs of the estimation errors at each stage. This method requires less number of multiplications than other adaptive la...1985
498 Simpson, Jamesina J.An efficient stochastic approach to uncertainty quantification in 3-D FDTD magnetized cold plasmaAn efficient stochastic finite-difference time-domain (S-FDTD) method is developed to analyze electromagnetic field variability in three dimensional anisotropic magnetized plasma. The new S-FDTD plasma model provides a full understanding of the true physics due to the associated uncertainties and ha...2014-01-01

500 Sung, Yun JuAn empirical comparison of meta-analysis and mega-analysis of individual participant data for identifying gene-environment interactionsMeta-analysis combining results from multiple studies is a standard practice in GWAS. For genetic main effects, meta-analysis has been shown to provide comparable results as mega-analysis that jointly analyzes the pooled data from the available studies. Gene-environment interaction (GEI) studies are...Gene-environment interactions2017
