Performance Analysis of Hybrid ARQ Protocols in a Slotted Code Division Multiple-Access Network by Joseph M Hanratty( Book )

1 edition published in 1989 in English and held by 2 WorldCat member libraries worldwide

A link throughput-delay analysis is presented for a slotted direct-sequence spread-spectrum multiple-access packet radio network (PRN) operating in the presence of background noise, multiple-access interference, and pulsed jammer noise. The PRN is comprised of an arbitrary number of full-duplex radio units arranged in a paired-off topology. Slotted ALOHA random access is used in conjunction with CDMA for channel access and a type I hybrid ARQ is used for error control. Expression are derived for the link throughput-delay in terms of the channel cutoff rate and capacity. With the friendly objective of maximizing the link throughput, and the enemy objective of minimizing the link throughput, the dependency of the optimal retransmission probability, processing gain, code rate, and jamming fraction on the population size, traffic intensity, bit energy-to-background-noise ratio, is examined in detail. It is shown that properly designed (optimized) PRN using random-access CDMA offers a significantly larger heavy load throughput than a random-access PRN. Theses. (RH)
Analysis of Knowledge-Based Expert Systems as Tools for Construction Design( )

1 edition published in 1991 in English and held by 2 WorldCat member libraries worldwide

Because construction costs are continuously rising, Congress mandated that those within the respective branches of military service who are responsible for planning and executing construction programs develop policies and procedures that ensure that the individual projects are designed, bid, and constructed as rapidly as possible. This requires an approach that demands maximum efficiency from the design process. Reviews are necessary to ensure that designs meet all requirements, but the reviews themselves must be conducted in the least amount of time so as to preclude delays. Design tools that increases efficiency are knowledge-based expert systems which are interactive computer programs that incorporate judgement, experience, rules of thumb, and other expertise, so as to provide knowledgeable advice about a specific domain. They mimic the thought process employed by a human expert in solving a problem
Study and analysis of speech parameters and display techniques( Book )

1 edition published in 1968 in English and held by 2 WorldCat member libraries worldwide

The research demonstrated the feasibility of the hybrid system approach to automatic speech processing. In particular, this approach appears suitable for acquiring statistics regarding a variety of acoustic properties of monosyllabic utterances over very large sample populations in a rapid and efficient manner. On the basis of experimental runs made with several types of normalization and scaling, it is concluded that the following procedure should be adopted in any further processing of data with the present hybrid system. It is felt that vectorgrams produced by the procedure used would be readily amenable to automatic pattern-recognition programming on the digital computer. (Author)
Extreme Values of Queues, Point Processes and Stochastic Networks( Book )

2 editions published in 1985 in English and held by 2 WorldCat member libraries worldwide

Work progressed on four topics. In modeling of stochastic flows in networks, compound Poisson approximations for random variables and point processes were developed. In extremal problems in stochastic networks, a family of bounds for the distributions of certain generic random variables were obtained. In optimization of queueing systems, progress was made in determining ways to control or dampen extremes of queues. Finally, research was begun on extreme values of queues and point processes.

Modeling Crosstalk on Printed Circuit Boards( Book )

1 edition published in 1985 in English and held by 2 WorldCat member libraries worldwide

The modeling of crosstalk on printed circuit boards is investigated. The emphasis is on simple models for use in CAD/CAM codes. Several simple models are developed. Their predictions are assessed for typical printed circuit board dimensions and interfering signals. The model predictions are compared to those of conventional lumped-circuit iterative models as well as experimental results. Also included are similar results for a ribbon cable. Keywords: Printed circuit board, Crosstalk, Coupling, Transmission Lines, Ribbon Cable, and Electromagnetic Compatibility
The Role of Self-Esteem and Self-Efficacy in Detecting Responses to Feedback( Book )

2 editions published in 1998 in English and held by 1 WorldCat member library worldwide

Our research on the relationships between individual differences, feedback seeking, and reactions to feedback sought to identify and clarify the existing state of knowledge concerning these relationships. We identified five individual difference variables that have historically been included in empirical feedback studies. These are: self-esteem, self-efficacy, locus of control, achievement need, and tolerance for ambiguity. Within the identified research, feedback-related responses were classified into five categories: affective reactions to feedback (e.g., satisfaction with the feedback), cognitive reactions to feedback (e.g., perceived accuracy), feedback monitoring (i.e., using indirect methods such as observing others to gain some performance information), feedback seeking (i.e., asking others for feedback), and other behaviors (often including performance following the receipt of feedback). The results of this investigation are summarized in Appendices A through E. In each appendix, the relationship between an individual difference and the responses given above are outlined. More specifically, the results for self-esteem are contained in Appendix A, for self-efficacy in Appendix B, for locus of control in appendix C, for tolerance for ambiguity in Appendix D, and need for achievement in Appendix E
Integrated Automatic Target Detection from Pixel-Registered Visual-Thermal-Range Images( Book )

2 editions published in 1998 in English and held by 1 WorldCat member library worldwide

This paper outlines a method to automatically detect targets from sets of pixel registered visual, thermal, and range images. The method uses operations specifically designed for the different kinds of images. It also introduces the morphological operation called erosion of strength n as a powerful tool for removal of spurious information. Good preliminary results obtained for detection support its suitability for application to the Automatic Target Recognition (ATR) problem
Integrated Diagnostics( Book )

3 editions published between 1997 and 1999 in English and held by 1 WorldCat member library worldwide

This document summarizes activity concerning the performance of basic research being conducted in the area of Integrated Diagnostics, a term associated with the technologies and methodologies used to determine how mechanical failures occur, and how they can be detected, predicted, and diagnosed in real time. Objectives, set forth through a Department of Defense Multidisciplinary Research Program of the University Research Initiative (M-URI), are being addressed by faculty and staff from the Georgia Institute of Technology, Northwestern University, and the University of Minnesota. Fourth year accomplishments and plans are reported upon. During this reporting period, experiments based on material, load, and vibration information from critical rotorcraft components continued so as to collect data of relevance in understanding the mechanisms of small crack growth for use in developing fatigue failure models. Such models serve as a guide in the selection and development of sensors to detect faults and pending failures. Effort has been placed on sensor development, and achieving the means to analyze and correlate reliable sensor output for operator use. Organizationally, this activity is being accomplished through (11) projects, categorized by the thrust areas of (1) Mechanical System Health Monitoring, including microsensor development and the condition monitoring of rotordynamic elements; (2) Nondestructive Examination Technology; and (3) Material Failure Characterization and Prediction Methodology

ARL Intranet Analysis and Development Study by Dana L Ulery( Book )

2 editions published in 1999 in English and held by 1 WorldCat member library worldwide

We analyze the concept and practice of Intranets used in midsize and large enterprises, focusing on their use and impact within research and development (R & D) organizations. We examine the shift from the old concept of business computing to the modern concept of enterprise computing, and consider Intranets-a class of enterprise computing-relative to enterprise computing trends. By analyzing in detail some case studies selected from the literature, on-site visits, and workshop discussions, we then offer three tools to frame the critical issues and provide structure for systematically constructing strategic Intranets specific to a given organization's mission and culture. Arguing that creation of an Intranet that projects an image of a world-class organization demands no less than a world-class enterprise that is strategically enabled through information technology, we then analyze the current U.S. Army Research Laboratory (ARL) Intranet and present a three-step action plan to expedite ARL's movement toward creation of such an Intranet
Final Report Summer Intern Program( Book )

2 editions published in 1998 in English and held by 1 WorldCat member library worldwide

This report summarizes the summer internship program conducted in 1996, supported by an ONR grant (N00014-92-J-1828, Georgia Tech budget C36-542). The report describes the work undertaken by the students, results of the program, and future plans. Overall, the internship program was a complete success. The goal of the internship program was to give socioeconomically disadvantaged undergraduate students an introduction to what graduate study in Computer Science is like and to encourage them to consider graduate education. A further goal was to build stronger relationships with local and national four year HBCUs (Historically Black Colleges and Universities). We also recruited students from HBCUs nationwide and worked in conjunction with the School of Electrical and Computer Engineering, which has a similar intern program, funded by the National Science Foundation. We worked very closely with local HBCU faculty to provide an internship program that was rewarding, challenging, enjoyable, and closely mentored
F-15 Tail Buffet Alleviation: A Smart Structure Approach( Book )

2 editions published in 1998 in English and held by 1 WorldCat member library worldwide

In high performance twin-tail aircraft fighter aircraft (HPTTA), tail buffet was first noticed through its destructive effects of induced fatigue cracks in the F-15 aircraft. The fatigue cracks were noticed shortly (less than six months) after the F-15 was placed in service and many high angles of attack maneuvers were executed. After repeated temporary structural fixes, a thorough investigation of the conditions leading to the crack confirmed that tail buffet is the cause of these effects. There are two significant effects of the buffet induced tail vibrations. These vibrations can restrict the flight maneuvering capability by restricting the angles of attack and speeds at which maneuvers such as the wind-up and wind-down turns can be executed. The second effect is caused by fatigue cracks and the resulting corrosion due to moisture absorption through the cracks. The objective of this work is to describe the results of our work in the area of buffet alleviation by the use of piezoceramic stack actuator assemblies
User Interfaces for Cooperative Remote Design( Book )

3 editions published between 1997 and 1998 in English and held by 1 WorldCat member library worldwide

Our objective in this research is to allow teams that are physically separated to do detailed design work on large-scale, 3D projects. The specific task is to enable multiple users to stand at each of two (or more) Virtual Workbenches at remote locations and interact effectively for design generation. Specific tasks completed include: (1) Organized and segmented the new Navy Arsenal Ship model; (2) Developed off-axis stereoscopic display and basic tracking mechanisms; (3) Developed an object data organization; (4) Generated nearly 1,000 3D objects and classified them using the data organization format; (5) Worked on several interaction paradigms, many of which are implemented in the design environment; (6) Developed a networking structure; and (7) Put together and are demonstrating a prototype design environment. In the coming year we will further study issues of collaboration and will also continue our work in enlarging and managing the set of objects in the ship design

Applications of Multiconductor Transmission Line Theory to the Prediction of Cable Coupling. Volume 7. Digital Computer Programs for the Analysis of Multiconductor Transmission Lines( )

1 edition published in 1977 in English and held by 0 WorldCat member libraries worldwide

Four digital computer programs, XTALK, XTALK2, FLATPAK, FLATPAK2, for determining the electromagnetic coupling within an (n+1) conductor, uniform transmission line are presented. Sinusoidal steady state behavior of the line as well as the TEM or 'quasi-TEM' mode of propagation are assumed. XTALK and XTALK2 consider lines consisting of n wires (cylindrical conductors) and a reference conductor. The surrounding medium is homogeneous and lossless. XTALK assumes that all (n+1) conductors are perfect conductors whereas XTALK2 considers the conductors to be lossy. There are three choices for the reference conductor: a wire, a ground plane, an overall cylindrical shield. FLATPAK and FLATPAK2 consider (n+1) wire ribbon (flatpack) cables in which all wires are identical and are coated with cylindrical, dielectric insulations of identical thicknesses. All wires lie in a horizontal plane and all adjacent wires are separated by identical distances. FLATPAK considers the wires to be perfect conductors and FLATPAK2 considers the wires to be lossy. The dielectric insulations are considered to be lossless. General termination networks are provided for at the ends of the line and the programs compute the voltages (with respect to the reference conductor) at the terminals of these termination networks for sinusoidal steady state excitation of the line
Applications of Multiconductor Transmission Line Theory to the Prediction of Cable Coupling. Volume 6. A Digital Computer Program for Determining Terminal Currents Induced in a Multiconductor Transmission Line by an Incident Electromagnetic Field( )

1 edition published in 1978 in English and held by 0 WorldCat member libraries worldwide

The report describes a digital computer program which is designed to compute the terminal currents induced in a multiconductor transmission line by an incident electromagnetic field. Sinusoidal steady state behavior of the line is assumed. The transmission line is uniform and consists of n wires and a reference conductor immersed in a homogeneous, lossless, linear, isotropic medium. The n wires and the reference conductor are assumed to be lossless. The reference conductor may be a wire, an infinite ground plane or an overall, cylindrical shield. The incident electromagnetic field may be a uniform plane wave or a general nonuniform field. The primary restriction on the program validity is that the cross sectional dimensions of the line, e.g., wire separation, must be much less than a wavelength
Information-Based Multisensor Detection( )

2 editions published between 2000 and 2001 in English and held by 0 WorldCat member libraries worldwide

This program addresses the Navy need for extended firm track range for low altitude cruise missiles through the integration of multiple sensors. Track-Before-Declare (TBD) techniques that utilize signal features are proposed for the synergistic integration of an Electronically Scanned Array (ESA) radar with other sensors for the detection of weak targets. The computer simulation models of the sensors will include the effects of many issues such as finite sensor resolution, limitations on the sensor resources, atmospheric refraction, sensor pointing errors, sea-surface induced multipath, nonhomogeneous clutter, sea clutter, etc. that are omitted in most of the legacy simulations. The two primary accomplishments for the first year of this program were the development of a phased array radar model with search and track management functions for multiple targets as well as the development of a sea-clutter model with moving target indicator (MTI) waveform designs
Applications of Multiconductor Transmission Line Theory to the Prediction of Cable Coupling. Volume 5. Prediction of Crosstalk Involving Twisted Wire Pairs( )

1 edition published in 1978 in English and held by 0 WorldCat member libraries worldwide

A transmission line model of the twisted wire pair is presented which may be used to compute electromagnetic coupling between the twisted wire pair and other circuits. The model is derived by representing the transmission line for the twisted wire pair as a cascade of uniform loops and 'abruptly' nonuniform twists. The overall transmission line matrix is found by cascading the chain parameter matrices, which represent the loops, with the permutation matrices, that represent the twists. Comparisons are presented between the twisted wire pair, the straight wire pair, and the single wire circuit configurations to determine the relative effectiveness in the reduction of electromagnetic coupling. Experimental results are compared to the model predictions which verify that the chain parameter model is accurate to within + or - 3 dB for frequencies such that the line is electrically short (i. e. 1/10 lambda). Finally a second model, the low frequency model, is presented and is shown to be as accurate as the chain parameter model in the prediction of coupling at low frequencies. This low frequency model is very appealing in that it is conceptually much easier to model and also less time consuming, computationally
