126 Sobh, Tarek M.; Henderson, Thomas C.Prototyping environment for robot manipulatorsDeveloping an environment that enables optimal and flexible design of robot manipulators using reconfigurable links, joints, actuators, and sensors is an essential step for efficient robot design and prototyping. Such an environment should have the right "mix" of software and hardware components for...Prototyping; Robot manipulators1994
127 Hansen, Charles D.Recent developments in parallel renderingUsing parallel computers for computer graphics rendering dates back to the late 1970s. Several papers published then focused on image space decompositions for theoretical parallel machines. Early research concentrated on algorithmic studies and special-purpose hardware, but the growing availability...Parallel rendering; Massively parallel processors1994
128 Brunvand, Erik L.Reduced latency self-timed FIFO circuitsSelf-timed flow-through FIFOs are constructed easily using only a single C-element as control for each stage of the FIFO. Throughput can be very high in FIFOs of this type because new data can be sent to the FIFO after communicating locally with only the first element of the FIFO. Therefore the thro...FIFO circuits; Self-timed; Flow-through; Reduced latency1994
129 Downes, Stephen M.Review of Michael Gorman, Simulating ScienceMichael Gorman has several projects in Simulating Science.

132 Berg, Cynthia A.Role of problem interpretations in understanding the development of everyday problem solvingImagine the following conversation between an 11-year-old and a 14-year-old. The two are fighting over how best to solve a problem that the 14-year-old experienced while working on a project at school. The problem involved completing the project so that it would be competitive for the class prize. T...1994
133 Gesteland, Raymond F.; Atkins, John F.; Wills, Norma M.rRNA-mRNA base pairing stimulates a programmed -1 ribosomal frameshiftBase pairing between the 3' end of 16S rRNA and mRNA is shown to be important for the programmed -1 frameshifting utilized in decoding the Escherichia coli dnaX gene. This pairing is the same as the Shine-Dalgarno pairing used by prokaryotic ribosomes in selection of translation initiators, but for ...Frameshifting; Escherichia coli; Binding Sites; Base Composition1994
134 Silverman, Randall H.Running on alkalineSixteenth, seventeenth and eighteenth century paper is unmistakable; it reeks of permanence. Its color, opacity and quality speak of strength and durability Handmade, you say? Cotton and linen fibers? True enough. But the longevity in these ancient sheets (noticeably lacking in much nineteenth and ...Alkaline pH; Precipitated calcium carbonate; Acid paper1994
135 Johnson, Christopher R.Semi-automatic image segmentation: a bimodal thresholding approachWe have developed a semi-automatic image segmentation tool which combines conventional manual segmentation utilities with a novel automatic image segmentation algorithm. Manual segmentation is achieved by dropping control points and fitting cubic splines to these points. Automatic segmentation is a...Image segmentation; Segmentation algorithms; Bimodal thresholding1994
136 Henderson, Thomas C.Sensing strategies based on manufacturing knowledgeWe propose an approach for the inspection of machined parts that is based on knowledge of the actual manufacturing process for the parts to be inspected. A principal benefit of this approach is that sensing can be focused on those areas of parts where violations of tolerance specifications are most ...Machined parts; Inspection; Sensing strategies; Toolpaths1994
137 Seger, JonSexual dimorphism in the HymenopteraSpectacular sex differences of many kinds occur abundantly among the wasps, bees and ants that make up the insect order Hymenoptera. In some cases these differences are so extreme that males and females of the same species have been classified in different genera for decades, until a chance observa...Reproductive; Insect; Morphology1994
138 Broughton, JohnSize of the bursa of fabricius in relation to gonad size and age in laysan and black-footed albatrossesAge determination can be difficult for birds that undergo little or no plumage change during life. This is the case for Laysan and Black-footed Albatrosses (Diomedea immutabilis and D. nigripes). The juvenile plumage for both these North Pacific albatrosses is completely grown by about five to six m...Birds; Species; Development1994
139 Bruderlin, BeatSketching as a solid modeling toolThis paper describes 'Quick-sketch', a 2-d and 3d modeling tool for pen based computers. Users of this system define a model by simple pen strokes drawn directly on the screen of a pen-based PC. Lines, circles, arcs, or B-spline curves are automatically distinguished and interpreted from these strok...Quick-sketch; Modeling tool; Pen based computers; Computer sketching1994
140 Miller, Jan D.;Yu, QiangSolvent refining of coal resin concentratesCertain bituminous coals of the western United States are known to contain appreciable quantities of macroscopic resinite (fossil resin). Such resinous coals are found in the states of Arizona, Colorado, New Mexico, Utah, Washington, Wyoming, etc. Among these, the Wasatch Plateau coal field in ce...1994
141 Morse, Michael DavidSpectroscopic analysis of the open 3 d subshell transition metal aluminides: AIV, AICr, and AICoThree open 3d subshell transition metal aluminides, AlV, AICr, and AlCo, have been investigated by resonant two-photon ionization spectroscopy to elucidate the chemical bonding in these diatomic molecules.
