An exploration of cyberspace security R & D investment strategies for DARPA : "the day after-- in cyberspace II" by Robert H Anderson( Book )

3 editions published in 1996 in English and held by 162 WorldCat member libraries worldwide

In recent years, a RAND-developed "The Day After ..." exercise methodology has been used to explore strategic planning options, both for nuclear proliferation and counter-proliferation, and for questions involving "security in cyberspace" and "information warfare" (IW). On March 23, 1996, a "The Day After ... in Cyberspace" exercise with approximately 60 participants was conducted at RAND's Washington D.C. offices, under the sponsorship of the Defense Advanced Research Projects Agency. The purpose was to generate suggestions and options regarding research and development initiatives to enhance the security of the U.S. information infrastructure. The scenario in the exercise involved a Mideast crisis situation, with Iran as an aggressor. Exercise participants discussed both short-term technical fixes to counter IW attacks that were hypothesized to occur in the year 2000 and longer-term research strategies that could be initiated now to avoid significant vulnerabilities in the future

REDUCE : software for algebraic computation by Gerhard Rayna( Book )

2 editions published in 1987 in English and held by 2 WorldCat member libraries worldwide

CONTRIBUTED BY DR. ANTHONY C. HEARN THE RAND CORPORATION, SANTA MONICA, CALIFORNIA REDUCE is a computer program for algebraic computation that IS III world-wide use by thousands of scientists, engineers, and mathematicians. Although it traces its beginnings to 1963, until recently it has only been available on main-frame computers because of its relatively large resource requirements. In 1980 I predicted (1) that by the mid-1980's it would be possible to obtain personal computers in the $10,000 $20,000 range capable of running REDUCE. I am therefore delighted to see that machines of the power of the IBM PC can now run this system, even though these computers are more modestly priced than my 1980 vision of the personal algebra machine. In addition to the need for the more widespread access that personal computers can now provide, there has been a longstanding need for a textbook to help the beginning user become better acquainted with the system. I am therefore very glad that Dr. Rayna has undertaken to write such a book, just as the era of the REDUCE personal algebra machine is beginning. In order to understand the nature of REDUCE, a little history is in order. In 1963 I met Dr. John McCarthy, the inventor of LISP

THE PROBLEM OF SUBSTITUTION( Book )

1 edition published in 1968 in English and held by 1 WorldCat member library worldwide

One of the most significant features of programs designed for non-numeric calculation is that the size of expressions manipulated, and hence the amount of storage necessary, changes continually during the execution of the program. It is therefore usually not possible for the user to know ahead of time just how much output his program will produce, or whether the calculation will in fact fail because of lack of available computer memory. The key to keeping both the size of intermediate expressions and output under control often lies in the manner in which substitutions for variables and expressions declared by the programmer are implemented by the system. In this paper various methods which have been developed to perform these substitutions in the author's own system REDUCE are discussed. A brief discription of the REDUCE system is also given.

Symbolic computation : directions for future research : report of a workshop on symbolic and algebraic computation, April 29-30, 1988, Washington, DC by Anthony C Hearn( Book )

2 editions published in 1989 in English and held by 1 WorldCat member library worldwide

REDUCE Users' Manual( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

REDUCE is a program designed for general algebraic computations of interest to physicists and engineers. Its capabilities include: Expansion and ordering of rational functions of polynomials; symbolic differentiation; substitutions in a wide variety of forms; reduction of quotients of polynomials by cancellation of common factors; calculation of symbolic determinants; calculations of interest to high energy physicists including spin 1/2 and spin 1 algebra. The program is written completely in the language LISP 1.5 and may therefore be run with little modification on any computer possessing a LISP 1.5 compiler or interpreter. (Author)
An Exploration of Cyberspace Security R&D Investment Strategies for DARPA by Robert H Anderson( )

1 edition published in 1997 in English and held by 1 WorldCat member library worldwide

High performance computing opportunities and challenges for Army R & D( )

2 editions published in 2006 in English and held by 0 WorldCat member libraries worldwide

The purpose of this study was to identify key potential users of high-performance computing (HPC) within the Army science and technology community and any barriers that prevent full use of current and planned HPC resources. A main study goal was to help develop an Army HPC strategy and build an HPC initiative that facilitates that strategy, thereby allowing the Army to compete effectively for Department of Defense HPC resources and to ensure that they are used for maximum effect in attacking the most difficult and computationally intensive research problems critical to future force and future combat systems achievement. Particular attention was given to applications of HPC in biotechnology and biomedicine and modeling and simulation of complex battlefield wireless network communication systems
Army medical support to the Army after next : issues and insights from the medical technology workshop, 1999 by Medical Technology Workshop( )

1 edition published in 2001 in English and held by 0 WorldCat member libraries worldwide

The Army Medical Department is planning now to ensure that the Army will have the required medical capabilities in 2025. As part of this planning, it conducted Medical Technology Workshop 1999 to investigate technologies for future medical concepts and capabilities. Besides gleaning insights from both the functional and technology perspectives into such areas medical informatics, combat service support, and biological and chemical defense, RAND analysts in this report identify areas warranting further investigation. The authors also discuss methods of improving future workshops
