Heat transfer and fire spread by Hal E Anderson ( )
2 editions published in 1969 in English and held by 195 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. (Author)
Mass transport in oxides; proceedings of a symposium held at Gaithersburg, Maryland, October 22-25, 1967 by J. B Wachtman ( Book )

An approach to replicated databases for robust command and control by Iris Kameny ( Book )
5 editions published between 1995 and 1996 in English and held by 158 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 types of command and control data that we address in this report include "situational awareness" data needed by Army tactical commanders from platoon through corps, including mission plan and progress, represented as machine-processable operation orders (OPORDs), enemy situation, and friendly situation and status. The concepts presented here were developed in answer to common objectives in two projects, a Distributed Databases project for the Advanced Research Projects Agency (ARPA) of the Department of Defense (DoD), and a project addressing the Management of Information for Joint and Combined Operations for the Army Office of the Director of Information Systems for Command, Control, Communications, and Computers (ODISC4). The report should be of interest to C2 operators and technologists concerned with digitization of the battlefield, tactical command and control, replicated distributed databases, and handling of asynchronous data on the battlefield

The RAND Advanced Simulation Language project's declarative modeling formalism (DMOD) by Jeff Rothenberg ( Book )
3 editions published in 1994 in English and held by 150 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
An optical signal processing model for the interferometric fiber optic gyro by Joseph M Aein ( Book )
in English and held by 147 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

New methods for robust science and technology planning by Robert J Lempert ( Book )
2 editions published in 1998 in English and held by 134 WorldCat member libraries worldwide
RAND researchers have conducted a successful proof-of-concept demonstration for the Defense Advanced Research Projects Agency (DARPA) of two new methods for science and technology (S&T) planning. These methods--HyperForum, a facilitated Web-based collaborative exercise, conducted in a carefully crafted, information-rich, online environment, and Exploratory Modeling, a new approach to generating systematic, quantitative comparisons among alternative policy decisions without relying on imperfect predictions of the future--exploit new information technologies in order to : improve the quality of the S&T planning process by using online computer-assisted decision-support tools that (1) make relevant information more easily available to expert panelists meeting over the World Wide Web, and (2) help panelists include and compensate for the effects of uncertainty by treating an S&T plan as a portfolio of technology investments hedged against a wide range of plausible futures; provide a lasting electronic archive of the expert discussions and other information that go into building an S&T plan; lower the travel-related costs and scheduling constraints of the current planning process by supplementing face-to-face expert panel meetings with asynchronous meetings over the World Wide Web. This documented briefing describes that demonstration. It should be of interest to decisionmakers responsible for choosing, managing, and justifying portfolios of science and technology research projects in the Department of Defense and other federal agencies, and in the private sector. In addition, it should be informative to those readers intereste

Analysis of random drop for gateway congestion control by Eman Salaheddin Hashem ( Book )
1 edition published in 1989 in English and held by 122 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.

Territorial waters in the Arctic: the Soviet position by S. M Olenicoff ( Book )
2 editions published in 1972 in English and held by 111 WorldCat member libraries worldwide
The Soviet Union maintains that its territorial waters, including those in the Arctic, extend 12 n mi from its coastline. It has also declared a 'sector claim' which Soviet jurists have unofficially interpreted to mean that the USSR also claims the airspace above the sector as well as the ice islands, the ice pack, and the waters between the Arctic Basin islands and between the islands and the mainland. These claims may become troublesome with the advent of surface-effect vehicles and submarine transports that will permit regular Arctic navigation. (Author Modified Abstract)
