The Organizational Consequences of Information Deployment

Description: This study investigates the influence that increasing end user autonomy has on organizational data models. The independence offered by microcomputer technology offers users increasing independence in their information-handling activities. As independence increases, uniformity of data models across the organization is theorized to diminish. The problem motivating this study is the potential for improper allocation of resources that may result from a misinterpretation of organizational data. This study suggests that the expanding use of microcomputers in the business setting will contribute to diversity of data models. This may eventually lead to confusion and even lack of confidence in the information produced.

A Comparison of Two Methods of Training Naive Users in the Use of a Microcomputer System

Description: The problem addressed in this study is the need for efficient and economic methods to train naive college students to operate microcomputers as a necessary step in their acquisition of computer proficiency. Two methods of training were compared. These were training by live demonstration and training by videotape. These methods were considered economically viable because each could be presented in a classroom and neither required a one-to-one student-to-computer or student-to-tutor ratio. Four sections of an introductory computer science class were used in the study. Two classes were presented each treatment. The effectiveness of the presentations was measured by means of a written quiz administered immediately after the presentation and by the number of microcomputer system operation tasks successfully completed during an individual laboratory session. The computer anxiety level of each participant was measured prior to the presentation to determine if anxiety was a factor in finding the best training method. When scores of naive users who saw the videotape were compared with the scores of naive users who saw the live demonstration, no significant differences were found. However, when novice users (those who had some previous experience with operating or programming a microcomputer) were included, the group that saw the videotape scored significantly higher on the written quiz than the group that saw the live demonstration. A two by two analysis of variance showed no significant interactions between anxiety and treatment. User satisfaction was found to be significantly higher for the videotape group than for the live demonstration group. This study concluded with the recommendation that the Computer Science Department of North Texas State University utilize videotapes to train students in introductory classes to use a microcomputer system. This recommendation was based on the superior test results for naive and novice users who saw the videotape, the user satisfaction scores ...

Assessing the Integration of Technology into the Academic Administrative Environment: College Administrators and Microcomputers

Description: This study was conducted to determine the administrative functions that community college academic administrators perform with microcomputers; to identify demographic characteristics that distinguish administrators who rate their overall use of the microcomputer higher than others; to ascertain whether the importance placed on (1) microcomputer uses, (2) computer training, and (3) non-training conditions affecting computer use differed from the perceived current uses, training, and adequacy of conditions. Data for this study were collected through a survey instrument that was devised and evaluated for use in the study. The survey instrument was delivered during the fall, 1984 semester to the forty—two division chairs serving at the seven colleges that comprise the Dallas County Community College District. Thirty five division chairs responded to the survey for an 83.33 per cent return rate, and thirty-four of the survey forms returned were useable for analysis.

Assessing the Use of Microcomputers by Administrators in Higher Education in Oklahoma

Description: This study was conducted to examine the use of microcomputers and other computers by top administrators in the twenty—seven public colleges and universities in Oklahoma; to assess the impact that training and other factors have on the extent to which microcomputers are being used; and to identify trends in administrative computer usage. The survey technique was utilized in collecting the data for this study. The survey instrument was developed for use in this study from a review of the literature, an evaluation by a panel of judges, and a pilot study. The survey instrument was sent to the administrators for business, academic, and student affairs via the president of each university in the 1986 spring and summer semesters. Seventy-four of the eighty-one or 91.4 percent of the administrators responded. Following is a summary of the major findings of this study. 1. Fourteen of the seventy-four or 18.9 percent of the respondents personally use a microcomputer and 51.3 percent of the respondents have someone use a microcomputer on their behalf. 2. The most prevalent use of microcomputers is word processing; the most prevalent uses of mainframes are word processing and database management; and the majority of the respondents do not use a computer for spreadsheets, graphics, database management, telecommunications, and time management functions. Computer functions rated highly important are word processing, spreadsheets, and database management. 3. Administrators feel they need more training in the use of computers. 4. Conditions affecting the use of microcomputers are an established process for evaluating software, funding for maintenance, and practice time. 5. Age is negatively correlated to the personal use of microcomputers. 6. Administrators believe that in the near future, the use of microcomputers will increase, the use of mainframes will remain about the same, and the number of jobs done without computers will decrease.

Assessing the Impact of the MAXHELP Microcomputer Orientation Course on Administrator, Teacher and Non-Educator Concerns Relating to Microcomputer Acceptance

Description: The problem this descriptive study dealt with was the fear (computerphobia) administrators, teachers, and noneducators have concerning the acceptance of microcomputers in the educational setting. The MAXHELP Project is an Air University sponsored program to assist the local schools in scientific and technological education. The 12 hour MAXHELP Microcomputer Orientation Course has graduated over 500 educators from seven Alabama school districts. This study used the Stages of Concern Questionnaire (SoCQ). This instrument was developed at the Inter-Institutional Program for the Reasearch and Development Center for Teacher Education, The University of Texas at Austin, by Hall, George and Rutherford. The SoCQ was mailed to a random sample of 300 MAXHELP graduates. A total of 212 responses were used in the study. This report concludes that the administrator and teacher groups are moving through the stages of concern when compared with the typical "non-user." Teachers show greater concerns relating to Management and administrators have greater concerns on Consequence, Collaboration, and Refocusing. Administrators are not users of microcomputers in the classroom, but are very concerned about how to facilitate the spread of microcomputers throughout the school curriculum. In general, the data indicate more similarity of teaching concerns by age, years teaching experience, and area of specialization. Concerns relating to the demands of microcomputers upon the individual who has to use microcomputers in the classroom cannot be satisfied without the microcomputer being available. Personal stage concerns will probably remain high until more microcomputers are available in the classroom. Teachers who have been in the classroom between one to six years appear to be the most prone to resist change. Special attention needs to be given to this group to demonstrate the advantages of the microcomputer as a teaching tool and as an administrative aid at both the pre-service and in-service levels.

Users Guide and Tutorial for PC-GenoGraphics: Version 1

Description: PC-GenoGraphics is a visual database/query facility designed for reasoning with genomic data. Data are represented to reflect variously accurate notions of the location of their sites, etc., along the length of the genome. Sequence data are efficiently stored and queried via a rather versatile language so that entire sequences of organisms will be treatable as they emerge. Other classes of information, such as function descriptions, are stored in a relational form, and joint queries relating these to sequence properties are supported. All queries result in visual responses that indicate locations along the genome. The results of queries can themselves be promoted to be queryable objects against which further queries can be launched.

Perceived Attitudes of Vocational Administrators, Vocational Office Education Teachers and Marketing and Distributive Education Teachers Toward Using Microcomputers in Vocational Education Programs

Description: The primary purpose of this study was to determine the perceived attitudes of vocational administrators, vocational office education teachers, and marketing and distributive education teachers toward using microcomputers in vocational education programs. The sample forth is study was randomly selected from all vocational administrators , vocational office education teachers, and marketing and distributive education teachers employed by Texas School Districts. A total of 288 questionnaire were returned from the three vocational education groups. The return was seventy-seven percent. Statistical techniques included descriptive statistics, one-way, and two-way analyses of variance (ANOVA) to describe the responses and to test the seven null hypotheses. The results of the study was reported in two categories: statistical significance of the tested hypotheses, and the educational inferences of the vocational administrators' and vocational teachers' responses to questionnaire items. There were significant differences in the perceived general attitudes of the three groups. There were no significant differences in the perceived general attitudes of the three groups when categorized by levels of age, occupational experience, amount of computer training, and availability of microcomputers. There were no significant differences in hypotheses which tested for differences in the perceived attitudes of the three groups toward utilizing microcomputers for classroom instruction and supportive services.

The Design of Microcomputer-Based Sound Synthesis Hardware

Description: Microcomputer-based music synthesis hardware is being developed at North Texas State University (NTSU). The work described in this paper continues this effort to develop hardware designs for inexpensive, but good quality, sound synthesizers. In order to pursue their activities, researchers in computer assisted instruction in music theory, psychoacoustics, and music composition need quality sound sources. The ultimate goal of my research is to develop good quality sound synthesis hardware which can fill these needs economically. This paper explores three topics: 1) how a computer makes music--a short nontechnical description; 2) what has been done previously--a review of the literature; and 3) what factors bear on the quality of microcomputer-based systems, including encoding of musical passages, software development, and hardware design. These topics lead to the discussion of a particular sound synthesizer which the author has designed.

A fast method for evaluating a simplified hot dry rock heat flow problem

Description: I present optimizations to the computation of Elsworth's single zone, hot dry rock thermal recovery model. These enhancements lead to as much as a 6-fold increase in computational speed. The greatest time savings derive from an efficient evaluation of the model's thermal response due to a step in heat flux, which is required for solution of the more general problem via Duhamel's Principle. Further enhancements come from taking advantage of the special structure of the model's finite difference equation. Reductions in execution speed were sought in order to facilitate the model's implementation on AT-class microcomputers. The PC-based application requires multiple evaluations of the model. Typical execution times on a 33 MHz 80386 microcomputer for 128 time steps were 7 seconds, as compared with 25-42 seconds for the non-optimized approach, and for 512 time steps were 28 and 100-168 seconds, respectively; the timing of the non-optimized method depended upon particulars of the dimensionless variables.

Tactile and Kinesthetic Controls for use in Interactive Mini andMicrocomputer Environments

Description: The traditional visual bias for computer-to-user communications seems to have reached the point of excluding other, non-traditional solutions to computer-user linkage problems. users, generally humans, are much more than simple video communicators and expanding the number of methods by which the computer converses with the user can be used to significantly enhance the intimacy of the relationship. Human communication channels include, in addition to video; sounds, tactile sensations (vibrations, temperature, direct electrical stimulation) and kinesthetic sensations (resistance to movement). This paper describes simple vibrating, kinesthetic and temperature-variable switches with respect to their implementation, their limitations and their potential applications. They conclude that such devices are generally simple to implement and control and offer substantial benefits to interactive environment users as mechanical ''pointers'' to appropriate response classes and as binary (yes/no) responders to specific user queries.

275 C Downhole Microcomputer System

Description: An HC11 controller IC and along with serial SRAM and ROM support ICs chip set were developed to support a data acquisition and control for extreme temperature/harsh environment conditions greater than 275 C. The 68HC11 microprocessor is widely used in well logging tools for control, data acquisition, and signal processing applications and was the logical choice for a downhole controller. This extreme temperature version of the 68HC11 enables new high temperature designs and additionally allows 68HC11-based well logging tools and MWD tools to be upgraded for high temperature operation in deep gas reservoirs, The microcomputer chip consists of the microprocessor ALU, a small boot ROM, 4 kbyte data RAM, counter/timer unit, serial peripheral interface (SPI), asynchronous serial interface (SCI), and the A, B, C, and D parallel ports. The chip is code compatible with the single chip mode commercial 68HC11 except for the absence of the analog to digital converter system. To avoid mask programmed internal ROM, a boot program is used to load the microcomputer program from an external mask SPI ROM. A SPI RAM IC completes the chip set and allows data RAM to be added in 4 kbyte increments. The HC11 controller IC chip set is implemented in the Peregrine Semiconductor 0.5 micron Silicon-on-Sapphire (SOS) process using a custom high temperature cell library developed at Oklahoma State University. Yield data is presented for all, the HC11, SPI-RAM and ROM. The lessons learned in this project were extended to the successful development of two high temperature versions of the LEON3 and a companion 8 Kbyte SRAM, a 200 C version for the Navy and a 275 C version for the gas industry.

Performance of scientific computing platforms running MCNP4B

Description: A performance study has been made for the MCNP4B Monte Carlo radiation transport code on a wide variety of scientific computing platforms ranging from personal computers to Cray mainframes. We present the timing study results using MCNP4B and its new test set and libraries. This timing study is unlike other timing studies because of its widespread reproducibility, its direct comparability to the predecessor study in 1993, and its focus upon a nuclear engineering code. Our results, derived from using the new 29-problem test set for MCNP4B, (1) use a highly versatile and readily available physics code; (2) show that timing studies are very problem dependent; (3) present the results as raw data allowing comparisons of performance to other computing platforms not included in this study to those platforms that were included; (4) are reproducible; and (5) provide a measure of improvement in performance with the MCNP code due to advancements in software and hardware over the past 4 years. In the 1993 predecessor study using MCNP4A, the performances were based on a 25 problem test set. We present our data based on MCNP4B`s new 29 problem test set which cover 97% of all the FORTRAN physics code lines in MCNP4B. Like the previous study the new test problems and the test data library are available from the Radiation Shielding and Information Computational Center (RSICC) in Oak Ridge, Tennessee. Our results are reproducible because anyone with the same workstation, compiler, and operating system can duplicate the results presented here. The computing platforms included in this study are the Sun Sparc2, Sun Sparc5, Cray YMP 8/128, HP C180,SGI origin 2000, DBC 3000/600, DBC AiphaStation 500(300 MHz), IBM RS/6000-590, HP /9000-735, Micron Milienia Pro 200 MHz PC, and the Cray T94/128.

Support of Gulf of Mexico Hydrate Research Consortium: Activities to Support Establishment of a Sea Floor Monitoring Station Project

Description: A Consortium, designed to assemble leaders in gas hydrates research, has been established at the University of Mississippi's Center for Marine Resources and Environmental Technology, CMRET. The primary objective of the group is to design and emplace a remote monitoring station on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station allows for the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. Establishment of the Consortium has already succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in this relatively new research arena. Complementary expertise, both scientific and technical, has been assembled to innovate research methods and construct necessary instrumentation. As funding for this project, scheduled to commence December 1, 2002, had only been in place for less than half of the reporting period, project progress has been less than for other reporting periods. Nevertheless, significant progress has been made and several cruises are planned for the summer/fall of 2003 to test equipment, techniques and compatibility of systems. En route to reaching the primary goal of the Consortium, the establishment of a monitoring station on the sea floor, the following achievements have been made: (1) Progress on the vertical line array (VLA) of sensors: Software and hardware upgrades to the data logger for the prototype vertical line array, including enhanced programmable gains, increased sampling rates, improved surface communications, Cabling upgrade to allow installation of positioning sensors, Incorporation ...

Description: This report summarizes work completed on DOE Contract DE-AC21-92MC28138, Development of a Natural Gas Systems Analysis Model (GSAM). The products developed under this project directly support the National Energy Technology Laboratory (NETL) in carrying out its natural gas R&D mission. The objective of this research effort has been to create a comprehensive, non-proprietary, microcomputer model of the North American natural gas market. GSAM has been developed to explicitly evaluate components of the natural gas system, including the entire in-place gas resource base, exploration and development technologies, extraction technology and performance parameters, transportation and storage factors, and end-use demand issues. The system has been fully tested and calibrated and has been used for multiple natural gas metrics analyses at NETL in which metric associated with NETL natural gas upstream R&D technologies and strategies under the direction of NETL has been evaluated. NETL's Natural Gas Strategic Plan requires that R&D activities be evaluated for their ability to provide adequate supplies of reasonably priced natural gas. GSAM provides the capability to assess potential and on-going R&D projects using a full fuel cycle, cost-benefit approach. This method yields realistic, market-based assessments of benefits and costs of alternative or related technology advances. GSAM is capable of estimating both technical and commercial successes, quantifying the potential benefits to the market, as well as to other related research. GSAM, therefore, represents an integration of research activities and a method for planning and prioritizing efforts to maximize benefits and minimize costs. Without an analytical tool like GSAM, NETL natural gas upstream R&D activities cannot be appropriately ranked or focused on the most important aspects of natural gas extraction efforts or utilization considerations.

Client/Server distributed processing using SunOS remote procedure protocol

Description: Over the last ten years the development of PC's and workstations has changed the way computing is performed. Previously, extensive computations were performed on large high speed mainframe machines with substantial storage capacity. Large capital and operational costs were associated with these machines. The advent of more powerful workstations has brought more computational cycles to the users at lower cost than was achieved with busy timesharing systems. However, many users still can't afford individual special purpose hardware or gigabytes of storage. A successful distributed processing environment must share these resources. Client/Server models have been proposed to address the issues of shared resources. They are not a new idea, but their implementation has been difficult. With the introduction of SUN's public domain Remote Procedure Call (RPC) Protocol and SUN's interface generator, RPCGEN, their implementation has been made easier. SUN has developed a set of C'' callable routines that handle the Client/Server operations. The availability of Network File System (NFS) on the SRL CRAY and the arrival of Wollongong's latest version of NFS has allowed applications and information sharing between computing platforms. This paper reviews the Client/Server model with respect to SUN's RPC implementation. The discussion will focus on the RPC connection between local and remote machines, the RPC Paradigm for making remote procedure calls, and the programming levels of the RPC libraries. The paper will conclude with summaries of two applications developed at SRL using the protocol and their effect on our computing environment. These include the Nuclear Plant Analyzer and an animation of fluids using behavioral simulation of atom-like particles.

The design of a scalable, fixed-time computer benchmark

Description: By using the principle of fixed time benchmarking, it is possible to compare a very wide range of computers, from a small personal computer to the most powerful parallel supercomputer, an a single scale. Fixed-time benchmarks promise far greater longevity than those based on a particular problem size, and are more appropriate for grand challenge'' capability comparison. We present the design of a benchmark, SLALOM{trademark}, that scales automatically to the computing power available, and corrects several deficiencies in various existing benchmarks: it is highly scalable, it solves a real problem, it includes input and output times, and it can be run on parallel machines of all kinds, using any convenient language. The benchmark provides a reasonable estimate of the size of problem solvable on scientific computers. Results are presented that span six orders of magnitude for contemporary computers of various architectures. The benchmarks also can be used to demonstrate a new source of superlinear speedup in parallel computers. 15 refs., 14 figs., 3 tabs.

Multiple crossbar network: Integrated supercomputing framework

Description: At Los Alamos National Laboratory, site of one of the world's most powerful scientific supercomputing facilities, a prototype network for an environment that links supercomputers and workstations is being developed. Driven by a need to provide graphics data at movie rates across a network from a Cray supercomputer to a Sun scientific workstation, the network is called the Multiple Crossbar Network (MCN). It is intended to be coarsely grained, loosely coupled, general-purpose interconnection network that will vastly increase the speed at which supercomputers communicate with each other in large networks. The components of the network are described, as well as work done in collaboration with vendors who are interested in providing commercial products. 9 refs.
