Face-To-Face Vs. Computerized Conferences : A Controlled Experiment. Volume I: Findings, Computerized Conferencing & Communications Center, Starr Roxanne Hiltz, Kenneth Johnson, Charles Aronovitch, Murray Turroff

Computerized Conferencing and Communications Center Reports

This is a report on the first controlled experiment conducted as part of a four year effort to explore the feasibility and effectiveness of using the computer to structure the communication for various types of group tasks. It uses a language called INTERACT, developed as part of this grant effort, to administer all instructions and conduct a group problem solving discussion in a computer conference. The experiment compares the process and outcome of face to face vs. computer mediated group problem solving discussions.

The objectives of this experiment are the following "basic research" questions:

Atomic Hydrogen Storage, John A. Woollam

Department of Electrical and Computer Engineering: Faculty Publications

Atomic hydrogen, for use as a fuel or as an explosive, is stored in the presence of a strong magnetic field in exfoliated layered compounds such as molybdenum disulfide or an elemental layer material such as graphite. The compound is maintained at liquid temperatures and the atomic hydrogen is collected on the surfaces of the layered compound which are exposed during delamination (exfoliation). The strong magnetic field and the low temperature combine to prevent the atoms of hydrogen from recombining to form molecules.

Electronic Properties Of Metal Chloride Intercalants Of Graphite*, **, John A. Woollam, M. B. Dowell, A. Yavrouian, A. G. Lozier, G. Matulka

Department of Electrical and Computer Engineering: Faculty Publications

The Shubnikov-deHaas (SdH) effect has been used to study the electronic properties of graphite intercalated with PdC1₂ (stage 3), FeC1₃ (stages 2, 4, 6, and 11), CuC1₂ (stage 1), and WC1₆ (stage 5). For the palladium chloride, ferric chloride, and copper chloride intercalants the SdH spectra are similar: these show frequencies of approximately, 27, 80, 380, and 550 Tesla for fields parallel to the c-axis. The effective masses have been measured for each of these carriers, and are of the order of 0.1 m₀, where m₀ is the free electron mass. These carriers …

Some Facts And Prospects For The Establishment Of Television Broadcasts In Mainland Tanzania, H. R. Mgombelo

Abstract

Synchronization Strategies, Mishell J. Stucki, Jerome R. Cox Jr

All Computer Science and Engineering Research

Computing systems are now frequently composed of independently clocked subsystems that cooperate to perform the function desired for the whole. This type of architecture has many advantages and promises to be the standard for the foreseeable future. With the trend towards more and more gates per chip, the number of chips per subsystem gets smaller and smaller, and we can expect to soon see one or more subsystems per chip. This transition will require contributions from disciplines previously outside the field of chip design, and every issue will have to be carefully worked out beforehand because debugging chips of this …

Atomic Hydrogen Storage Method And Apparatus, John A. Woollam

Department of Electrical and Computer Engineering: Faculty Publications

Atomic hydrogen, for use as a fuel or as an explosive, is stored in the presence of a strong magnetic field in exfoliated layered compounds such as molybdenum disulfide or an elemental layer material such as graphite. The compound is maintained at liquid helium temperatures and the atomic hydrogen is collected on the surfaces of the layered compound which are exposed during delamination (exfoliation). The strong magnetic field and the low temperature combine to prevent the atoms of hydrogen from recombining to form molecules.

Information Systems For Natural Resources Managers: An Exercise In Interfacing, Connie L. Knapp

Marine Affairs Theses and Major Papers

This thesis proposes guidelines for achieving the human interfaces which are requisite to the development and operation of natural resources information systems. Conclusions were drawn from an evaluation of past experiences in building and attempting to use these types of systems. Both successful and unsuccessful systems were considered, as well as the current effort in Rhode Island to develop a system for coastal resources managers. Examples are presented to support particular conclusions and recommendations. The perspective is nontechnical. Examples and recommendations, therefore, are conceptual rather than quantitative or technical. While a variety of mechanisms can be used to achieve the …

Computer Graphics: Conversion Of Contour Line Definitions Into Polygonal Element Mosaics, Thomas W. Sederberg

Theses and Dissertations

There has been a disparity between the conventional method of describing topographic surfaces (i.e. contour line definition) and a format of surface description often used in continuous-line computer graphics (i.e. panel definition). The two differ enough that conversion from contours to panels is not a trivial problem. A computer program that performs such a conversion would greatly facilitate continuous tone display of topographical surfaces, or any other surface which is defined by contour lines.

This problem has been addressed by Keppel and alluded to by Fuchs. Keppel's is a highly systematic approach in which he uses graph theory to find …

Programming Language Requirements For Human Communication Structures Or Computer Conferencing, Computerized Conferencing & Communications Center, Peter Gordon Anderson

Computerized Conferencing and Communications Center Reports

Our overall goal is to be able, simply and quickly, to construct computer conferencing systems for new requirements, applications, and even experimental ideas or fantasies. One way to view this requirement is as the creation of a highly parameterized conferencing system itself. Our view, however, is that of a programming language; i.e., an integrated notational system for the specification of communication structures and the associated actions or computation to be taken by the computer system hosting the structure.

A communication structure consists of a group of people (and storage devices) each endowed with some characteristics, and some means of person-to-person …

Design Of A Microprocessor Controlled Telecommunication System, George J. Maroutsos

Dissertations and Theses

Recent advancements in Large Scale Integration Technology have made available devices, such as microprocessors, analog gates and "three state" logic, that provide the designer with a wide range of possibilities in the design of telecommunication systems. A microprocessor and analog gates are utilized in this design to demonstrate the feasibility of implementing a flexible Telecommunication System. The microprocessor is programmed to control, through software, the system functions. The feasibility of systems highly adaptable to the needs of individual subscribers is thus demonstrated.

Communication Processes In The Design And Implementation Of Models, Simulations And Simulation-Games: A Selective Review And Analysis, From The Vantage Point Of Computerized Conferencing, Computerized Conferencing & Communications Center, Julian M. Scher

Computerized Conferencing and Communications Center Reports

Computerized conferencing is a new form of communication which permits a group of individuals, who could be separated in time as well as space, to engage in an interactive dialogue with each other through the convenience of their computer terminals. The software for a computerized conferencing system is designed to keep track of all messages communicated in the system, as well as insure that the various protocols for communication are observed by all.

Our objectives in this report are to examine the communication processes found in the design and implementation of models, simulations and simulation-games, and to identify those areas …

Computerized Conferencing And The Homebound Handicapped, Computerized Conferencing & Communications Center, Murray Turoff, Howard Gage

Computerized Conferencing and Communications Center Reports

Computer conferencing is a relatively new technique which can be applied to improve both the efficiency of education, and communication services available to the homebound handicapped. A system is currently being implemented at the New Jersey Institute of Technology which allows such individuals to engage in a written form of conversation with other individuals or groups. Here the computer stores the discus­sion and keeps track of what everyone has or has not seen, so participants can communicate at a time and pace of their choosing. There is also provision for a range of ancillary facilities such as voting, word processing, …
