1 Henderson, Thomas C.2-D scene analysis using split-level relaxationWe present a new method for applying multiple semantic constraints based on discrete relaxation. A separate graph is maintained for each constraint relation and used in parallel to achieve a consistent labeling. This permits both local and global analysis without recourse to complete graphs. Here l...Discrete relaxation; Split-level relaxation1985
2 Bhanu, Bir3-D model building for computer visionThis paper presents a Computer-Aided Geometric Design (CAGD) based approach for building 3-D models which can be used for the recognition of 3-D objects for industrial machine vision applications. The objects are designed using the Alpha_1 CAGD system developed at the University of Utah. A new metho...CAGD; 3-D models; Machine vision1985
3 Cohen, ElaineA new local basis for designing with tensioned splinesRecently there has been a great deal of interest in the use of "tension" parameters to augment control mesh vertices as design handles for piecewise polynomials. A particular local cubic basis called p-splines, which has been termed a "generalization of B-splines", has been proposed as an appropriat...Tensioned splines1985
4 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
5 Mathews, V. JohnAnalysis of the short-time unbiased spectrum estimation algorithmAbstract- The short-time unbiased spectrum estimation (STUSE) algorithm is analyzed and expressions for the mean and variance of the spectrum estimates are derived. The STUSE algorithm deliberately adds biased spectrum estimates in order to yield unbiased estimates and at the same time have excellen...1985
6 Henderson, Thomas C.Arc and path consistency revisitedMackworth and Freuder have analyzed the time complexity of several constraint satisfaction algorithms [4]. We present here new algorithms for arc and path consistency and show that the arc consistency algorithm is optimal in time complexity and of the same order space complexity as the earlier algor...Arc consistency; Path consistency; Constraint satisfaction algorithms1985
7 Ailion, David Charles; Morris, Alan H.Asymmetric spin echo sequences. a simple new method for obtaining NMR 1H spectral imagesThe nuclear magnetic resonance (NMR) signal decay produced by reversible tissue-induced dephasing of the magnetization components in the transverse plane (reversible tissue-induced dephasing) was measured and expressed as a function of a new transverse relaxation time T'2 (T2 prime) for samples of ...Asymmetric spin echo; Signal decay; Chemical shift; Tissue characterization; Lung aeration; Fatty liver1985
8 Henderson, Thomas C.; Bhanu, BirCAGD based 3-D visual recognitionA coherent automated manufacturing system needs to include CAD/CAM, computer vision, and object manipulation. Currently, most systems which support CAD/CAM do not provide for vision or manipulation and similarly, vision and manipulation systems incorporate no explicit relation to CAD/CAM models. CAD...Object manipulation; CAGD1985
9 Ailion, David CharlesCommensurability and defect-induced phason gaps in incommensurate systemsThe phason energy gap has been observed to increase on going from the incommensurate to higher-order commensurate phases in the "devil's staircase" compound [N(CH3)4]2ZnCl4. The gap was determined via the phason-induced 1 4N spin-lattice relaxation contribution, which was obtained from the variati...Phasons; Commensurate; Incommensurate; Lattices; Modulation1985

12 Olivera, Baldomero M.; Gray, William Robert; Yoshikami, DojuConus geographus toxins that discriminate between neuronal and muscle sodium channelsWe describe the properties of a family of 22-amino acid peptides, the μ-conotoxins, which are useful probes for investigating voltage-dependent sodium channels of excitable tissues. The μ-conotoxins are present in the venom of the piscivorous marine snail, Conus geographus L. We have purified even...Conus geographus; Venom; Conotoxins; Sodium channels; Neurotoxins1985

14 Pounder, Diana G.Decision making in videotaped selection interviews: age and position effects retestedThis study was designed to test the effects of a candidate's age and the effect of the type of position under consideration on candidate ratings as assessed from a videotaped interview simulation. To investigate the effect of these variables, a 2 x 2 factorial design was used. The independent varia...1985

16 Miller, Jan D.; Herbst, John A.; Lin, Chen-LuhDevelopment of a multicomponent-multisize liberation modelThis paper is concerned with the development of a kinetic model for mineral liberation by grinding. Existing population balance size reduction models are extended to include two minerals with an arbitrary number of locked particle fractions. The validity of this approach to liberation modelling is d...Population balance; size reduction; liberation; grinding model1985

S. Department of Transportation, Federal highway Administration.1985
18 Vardeny, Zeev ValentineEffect of bias illumination on photoinduced absorption decay in ?-Si:HZeldov and Weiser1 proposed a model to explain the influence of optical biasing on the decay of photoinduced absorption (PA) in ?-Si:H at high temperatures observed by Pfost, Vardeny, and Tauc.2 This model differs from the model originally used2 for interpreting the experimental data at temperatures...Optical biasing; Bias illumination; Photoinduced absorption decay; a-Si:H; Amorphous silicon1985
19 McCullough, John M.Evidence for assortative mating and selection in surnames: a case from Yucatan, MexicoSurnames are often used as metaphors for genetic material on the assumption of neutrality and general immunity from systematic pressures. The Yucatec Maya use surnames of both Maya and Spanish origin. We find evidence of positive assortative mating by ethnic origin of surname and a slight bias away ...Surnames; Assortative mating; Maya1985
20 Davidson, Diane W.Experimental study of diffuse competition in harvester antsExperiments carried out over a 5-yr period in the Chihuahuan Desert support the a priori prediction of diffuse competition between two species of harvester ants. Despite dietary overlap between a large species {Pogonomyrmex rugosus) and a small species (Pheidole xerophila), the large species facilit...Chihuahuan Desert; Ants; Facilitation; Resource allocation; Granivory1985
21 Brinkman, Paul T.Financial impact of part-time enrollments on two-year colleges: a marginal cost perspectiveThe number of part-time students attending public two-year colleges increased rapidly during the 1970s. By the end of the decade, aggregate part-time enrollment constituted about 63 percent of total headcount enrollment at those institutions. Concern has been expressed about the financial implicatop...Students; Part-time; Full-time; Colleges; Costs1985
22 Davidson, Diane W.Granivory in the Chihuahuan Desert: interactions within and between trophic levelsWe investigated the effects of Chihuahuan Desert granivores on three seasonal classes of plant resource species, the effects of these resource classes on one another, and the ways in which interactions through plant resources affect the abundances of seed consumers. At our study site, three seasona...Annual plant; Ant; Competition; Community; Desert; Ecosystem structure; Experiment; Granivore; Indirect interaction; Rodent; Population cycles; Seed predation1985
