3d Location Of Circular And Spherical Features By Monocular Model-Based Vision, Y. C. Shiu, Shaheen Ahmed Mar 1989

3d Location Of Circular And Spherical Features By Monocular Model-Based Vision, Y. C. Shiu, Shaheen Ahmed

Department of Electrical and Computer Engineering Technical Reports

This paper addresses the mathematics for using monocular model-based vision to find the 3-D positions of circular and spherical model features, and, for the circular case, orientations as well. Monocular model-based vision here refers to the use of a single projective image of modeled objects to solve for the 3-D positions and orientations of the objects in the scene. The mathematics for solving 3-dimensional position and orientation of the object from matched model and image points/lines features are well known. However, no known paper addresses spherical features arid very few papers address the mathematics involving circular model features. This paper …


Adding Slip Support To Unix System V, K. B. Sheets Mar 1989

Adding Slip Support To Unix System V, K. B. Sheets

Department of Electrical and Computer Engineering Technical Reports

SLIP (Serial Line Internet Protocal)[ROMK88][KARE86] is a means by which a serial line may be used as the data link interface for TCP/IP communication [POST80]. This document describes software which can be used to enable a computer running UNIX* System V Release 3 and equipped with the WIN3B [TWG86] software to utilize SLIP. This software is necessary to our organization since we have several UNIX machines for which no Ethernet interfaces are available and from which we would like to be able to access the campus network.

Scatchard Analysis Of Methane Sulfinic Acid Production From Dimethyl Sulfoxide: A Method To Quantify Hydroxyl Radical Formation In Physiologic Systems, Charles F. Babbs, David W. Griffin Jan 1989

Scatchard Analysis Of Methane Sulfinic Acid Production From Dimethyl Sulfoxide: A Method To Quantify Hydroxyl Radical Formation In Physiologic Systems, Charles F. Babbs, David W. Griffin

Weldon School of Biomedical Engineering Faculty Publications

A major impediment to the confirmation of free radical mechanisms in pathogenesis is a lack of direct, chemical evidence that oxygen centered free radicals actually arise in living tissues in quantities sufficient to cause serious damage. This investigation was conducted to validate the use of dimethyl sulfoxide (DMSO) as a quantitative molecular probe for the generation of hydroxyl radicals (HO*) under physiologic conditions. Reaction of HO* with DMSO produces methane sulfinic acid (MSA) as a primary product, which can be detected by a simple colorimetric assay. To develop a method for estimating total HO* production, we studied two model systems: …


Consequences Of Valley Filtering On Abrupt Junction Algaas/Gaas Heterojunction Bipolar Transistors, Amitava Das, Mark S. Lundstrom Jan 1989

Consequences Of Valley Filtering On Abrupt Junction Algaas/Gaas Heterojunction Bipolar Transistors, Amitava Das, Mark S. Lundstrom

Department of Electrical and Computer Engineering Faculty Publications

Electron transport in AlGaAs/GaAs heterojunction bipolar transistors with compositionally abrupt emitter‐base junctions is examined. Transport across the abrupt emitter‐base heterojunction is treated quantum mechanically, and the Monte Carlo technique is used to study transport through the base. Although there is a sizeable population of upper‐valley electrons in the bulk emitter, the AlGaAs/GaAs heterojunction is found to favor the injection of Γ‐valley electrons into the base. This valley filtering effect enhances device performance by reducing base transit time, but quantum mechanical tunneling lowers the average energy of the injected flux which increases base transit time. The design of a heterojunction bipolar …


Effective Minority‐Carrier Hole Confinement Of Si‐Doped, N+‐N Gaas Homojunction Barriers, H. L. Chuang, M. E. Klausmeier-Brown, Michael R. Melloch, Mark S. Lundstrom Jan 1989

Effective Minority‐Carrier Hole Confinement Of Si‐Doped, N+‐N Gaas Homojunction Barriers, H. L. Chuang, M. E. Klausmeier-Brown, Michael R. Melloch, Mark S. Lundstrom

Department of Electrical and Computer Engineering Faculty Publications

he electrical performance of Si‐doped n+‐n GaAs homojunction barriers grown by molecular‐beam epitaxy (MBE) is characterized and analyzed. We employed a successive etch technique to study hole injection currents in GaAs n+‐n‐p+ solar cells. The results of the analysis show that minority‐carrier holes in our MBE‐grown material have a mobility of 293 cm2/V s for an n‐type Si‐doping level of 1.5×1016 cm−3 at 300 K. The interface recombination velocity for these homojunction barriers is estimated to be less than 1×103 cm/s, and it appears to be comparable to that recently observed for …
