Object representation in computer vision : International NSF-ARPA Workshop, New York City, NY, USA, December 5-7, 1994 : proceedings by Martial Hebert( Book )

5 editions published in 1995 in English and Undetermined and held by 276 WorldCat member libraries worldwide

This book documents the scientific outcome of the International NSF-ARPA Workshop on Object Representation in Computer Vision, held in New York City in December 1994 with invited participants chosen among the recognized experts in the field. The volume presents the complete set of papers in revised full-length versions. In addition, the first paper is a report on the workshop in which the panel discussions as well as the conclusions and recommendations reached by the workshop participants are summarized. Altogether the volume provides an excellent, in-depth view of the state of the art in this active area of research and applications
Heat transfer and fire spread by Hal E Anderson( )

2 editions published in 1969 in English and held by 265 WorldCat member libraries worldwide

"Experimental testing of a mathematical model showed that radiant heat transfer accounted for no more than 40% of total heat flux required to maintain rate of spread. A reasonable prediction of spread was possible by assuming a horizontal convective heat transfer coefficient when certain fuel and flame characteristics were known. Fuel particle size had a linear relation to residence time of the flame while fuel bed porosity influenced burning rate. Burning regimes of liquid pool fires (turbulent, transitional, and laminar) appeared to also apply to moving fires in solid fuels."

An approach to replicated databases for robust command and control by Iris Kameny( Book )

3 editions published between 1995 and 1996 in English and held by 159 WorldCat member libraries worldwide

This report presents an approach to making future command and control data more timely and robust through the use of replicated distributed data management techniques. The report includes "situational awareness" data needed by Army tactical commanders from platoon through corps, including mission plan and progress, represented as machine-processable operation orders, enemy situation, and friendly situation and status. The conceptual solution described in the report would give warfighters near-real-time common pictures of the battlefield for situational awareness in spite of communication delays due to jamming and congestion, network partitioning, node failures, and other hostile actions that might interfere with the rapid dissemination of data

An optical signal processing model for the interferometric fiber optic gyro by Joseph M Aein( Book )

5 editions published in 1995 in English and held by 154 WorldCat member libraries worldwide

This report presents the results of a communication theoretic model used to analyze the operation of Interferometric Fiber Optic Gyroscopes (IFOG). The IFOG is an all-solid-state rotation-rate sensor employed in miniature inertial measurement units (MIMU). The IFOG can achieve a navigation grade of performance (0.01 degree/hour drift rate) and offers the considerable advantage of reducing instrument costs by a factor of two or more over the current ring laser gyroscope (RLG) technology base. A simplified classical propagation model is used to describe the optical beams employed. Optical signal modulation is impressed with the following goals: (1) increase the linearity of the rotation-rate measurement and (2) mitigate the deleterious effects of the optical scatter noise unavoidably generated by the desired light beams as they traverse the optical pathways of the IFOG. This report deals with goal (1) above. The following are analyzed: (1) AC bias modulation used to linearize the IFOG instrument; (2) closed-loop, feedback operation to extend the dynamic range; and (3) serrodyne operation. The analysis establishes the performance relationships among the appropriate optical signal parameters and allows for their optimization
The RAND Advanced Simulation Language project's declarative modeling formalism (DMOD) by Jeff Rothenberg( Book )

2 editions published in 1994 in English and held by 149 WorldCat member libraries worldwide

This report discusses research by the RAND Advanced Simulation Language (RASL) project. The objective of this research project has been to develop knowledge-based techniques that integrate simulation and planning to answer strategic mobility questions that go beyond the What if ...? capabilities of traditional simulation: questions such as Can a give event ever happen? Under what conditions will an event happen? or 'How can a desired result be achieved?' The strategic mobility planning problem encompasses a wide range of issues concerning which transportation assets (ships, planes, etc.) to acquire and how to use them to transport personnel and materiel to satisfy mission objectives. The RASL project is researching new modeling techniques that will allow simulation and planning to be performed in an integrated fashion, using a single, underlying model of the strategic mobility domain. This project has developed a new declarative modeling formalism (DMOD) for modeling and reasoning about dynamic systems

Analysis of random drop for gateway congestion control by Eman Salaheddin Hashem( Book )

1 edition published in 1989 in English and held by 133 WorldCat member libraries worldwide

The growing demand on the Internet has prompted the need for more effective congestion control policies. Currently No Gateway Policy is used to relieve and signal congestion, which leads to a degradation of overall network performance. This thesis uses network simulation to illustrate the character of Internet congestion and its causes. It considers a newly proposed gateway congestion control policy, called Random Drop, as a promising solution. Random Drop relieves resource congestion upon buffer overflow by choosing a random packet from the service queue to be dropped. The random choice should result in a drop distribution proportional to the bandwidth distribution among all contending TCP connections. The simulation experiments demonstrate several shortcomings with this policy. Because Random Drop is a congestion control policy, which is not applied until congestion has already occurred, it usually results in a high drop rate that hurts too many connections including well- behaved ones. A modification of Random Drop to do congestion avoidance by applying the policy early was also proposed. Early Random Drop to do congestion avoidance by applying the policy early was also proposed. Early Random Drop has the advantage of avoiding the high drop rate of buffer overflow. The early application of the policy removes the pressure of congestion relief and allows more accurate signaling of congestion. Algorithms for the dynamic adjustment of the parameters of Early Random Drop to suite the current network load must still be developed.

Optoelectronic packaging by Alan Rolf Mickelson( Book )

6 editions published in 1996 in English and Undetermined and held by 132 WorldCat member libraries worldwide

The rapidly expanding field of packaging for optoelectronic devices challenges electrical engineers with a host of complex and daunting problems. The increasing intricacy of assemblage compounds the thorny interconnection issues associated with electronic packaging-how to assemble an array with many elements efficiently while maintaining thermal tolerance and simultaneously overcoming the ensuing modulation problems that generate electrical noise. Adding to these problems has been the absence, until now, of a single authoritative reference on the subject
