The role of faith-based organizations in HIV prevention and care in Central America by Kathryn Pitkin Derose( Book )
4 editions published in 2010 in English and Spanish and held by 11 libraries worldwide
Describes the involvement of churches and other faith-based organizations (FBOs) in addressing the HIV/AIDS epidemic in Belize, Guatemala, and Honduras. The authors describe the range of FBO activities and discuss the advantages and challenges to such involvement and possible ways that FBOs can enhance their efforts, both independently and in collaboration with other organizations, such as government ministries of health
Mathematical simulation of the effects of ionizing radiation on semiconductors ( Book )
6 editions published between 1968 and 1972 in English and held by 6 libraries worldwide
The report outlines the results of four mathematical investigations initiated during the present contract period: the high-low semiconductor junction, the junction field-effect transistor, the measurement of impurity atom distributions by differential capacitance techniques, and the electrical properties of a diffused semiconductor resistor. Two of these investigations remain incomplete; therefore, the information presented here constitutes a status report for these projects. The remaining two projects have been completed, and the information presented here summarizes all final conclusions derived from these mathematical investigations. (Author)
Computer aided engineering of semiconductor integrated circuits by David P Kennedy( Book )
3 editions published between 1976 and 1977 in English and held by 3 libraries worldwide
The objectives of this program are to remove the empiricism associated with the design and manufacturing of custom integrated circuits and to reduce the cost of these circuits by devising improved computer-aided engineering techniques. During this period emphasis has been placed on integrated circuit device and process modeling. For device modeling the results presented include the: (1) development of two-dimensional model for MOS and bipolar transistors; (2) development of a one-dimensional mathematical model for MOSFET operation; (3) studies on equivalent circuit modeling of transistor operation; (4) theoretical investigations of carrier mobility in the inversion layer of an MOSFET; (5) mathematical investigations for high-speed analysis of devices; (6) sheet resistivity test pattern model development, using Monte-Carlo techniques; and (7) hot carrier studies for inhomogeneous semiconductor material. For process modeling the results presented include (1) ion implantation; (2) thermal oxidation and chemical vapor deposition; (3) silicon epitaxy; and (4) thermal diffusion. (Author)

Physical models of MOSFET devices by David P Kennedy( Book )
2 editions published in 1975 in English and held by 2 libraries worldwide
This report presents research directed toward the development of a mathematical model for MOSFET operation that is based upon physical mechanisms associated with the operation of this semiconductor device. A principal objective of this effort is to develop a simple engineering type model that implicitly contains two-dimensional mechanisms known to exist in this device. Included in this objective is the development of a lumped network representation for MOSFET operation that can be expanded to include these two-dimensional mechanisms of operation. Chapter I of this final report outlines a mathematical model for MOSFET operation that appears applicable into the weak inversion mode of operation. Chapter 2 presents a quantum mechanical solution for the inversion layer carrier distribution in a MOSFET. Chapter 3 provides a first step toward the development of a lumped network representation for the MOSFET that is based upon first principles
Man-Machine Systems for Detection, Recognition, Transmission and Perception of Information. Volume I ( Book )
1 edition published in 1971 in English and held by 1 library worldwide
The report describes the results of a comprehensive research effort consisting of experimental and theoretical studies to develop man-machine techniques for processing data from sonar display systems. The following basic areas were investigated; Modeling of the human operator in sequential visual detection tasks; Compact encoding of information; Automatic methods of processing sonar data; and Visual display processing.

Vertical Transistor Investigation for I2L Structures ( Book )
1 edition published in 1977 in English and held by 1 library worldwide
A one-dimensional mathematical model is presented for the vertical transistor associated with an I2L semiconductor device. This particular model represents a modification of similar models used for bipolar transistor operation; it requires little computer time and has been subjected to extensive verification over past years. Although incomplete in its present form, the model suggested here is based upon the physical mechanisms encountered during semiconductor device operation. For this reason, it is suggested that little additional effort would be required to complete this model, including the physical mechanisms associated with damage arising from an ionizing type of radiation environment.

Man-Machine Systems for Detection, Recognition, Transmission, and Perception of Information. Volume II ( Book )
1 edition published in 1971 in English and held by 1 library worldwide
The purpose of this study was to develop a mathematical model of perceptual information processing that might be applied to engineering problems involving the use of an operator in a signal/information processing task. Using as a foundation the more basic and general psychological findings a predictive momodel was formulated which interactively incorporated this past research. The model formulation described a means of characterizing the ability of people to use information both for discrimination and identification tasks. Information processing was considered in an independent manner. A sequential logarithmic means of processing information was proposed which not only agreed with the results of past research but also provided a reasonably accurate simulation of both response accuracy and response time during the experimental study. A Bayesian means of characterizing the behavioral adjustments of both response accuracy and response time was proposed which used a memory of past responses to 'learn' the probabilities of the stimuli.

Two-Dimensional Avalanche Breakdown in Pt-Si Schottky Barrier Diodes ( Book )
1 edition published in 1979 in English and held by 1 library worldwide
The development of a two-dimensional computer model was undertaken for calculating avalanche breakdown in a Pt-Si Schottky barrier diode. A principal objective of this program was to develop such a computer program, and make the source-code and operational data available to other workers in the field. Further, as a means to verify the applicability of this program junction, breakdown computations were to be undertaken throughout a wide range of physical parameters and ambient temperatures

Investigation and Study of Computational Techniques for Design and Fabrication of Integrated Electronic Circuits ( Book )
1 edition published in 1975 in English and held by 1 library worldwide
Under ARPA Grant MDA903-74-G5, the University of Florida, Gainesville, Florida, has undertaken a program of study on the topic of Computer Engineering of Integrated Circuits. The purpose of this program was to identify problem areas associated with the design and development of integrated semiconductor circuits; problem areas that result in excessive cost and inadequate availability of the particular type electronic structures required by the DoD. An additional purpose of this study is to recommend a program of research and development directed toward alleviating the identified problem areas
Investigation of the Current Voltage Relationship for Low Barrier Schottky Diodes ( Book )
1 edition published in 1982 in English and held by 1 library worldwide
A model is developed for the current voltage characteristics of metal, p-type semiconductor Schottky barriers. The model accounts for transition of electrons from the semiconductor valence band to empty states below the metal Fermi energy. These transitions lead to an effective barrier energy that is lower than predicted by classical models. The model also includes two junction current mechanisms that give rise to higher reverse currents than that predicted classically. (Author)
Man-Machine Systems for Detection, Recognition, Transmission, and Perception of Information. Volume III ( Book )
1 edition published in 1971 in English and held by 1 library worldwide
The basic definitions of probabilistic languages and grammars are given. Derivations by such grammars are demonstrated and the probability distribution over the language generated by such a grammar is shown to have a sum-of-products form. Equivalence of probabilistic grammars is discussed and transformations on such grammars are investigated. The determination of a probabilistic grammar for a specified probabilistic language is investigated and the average word length of probabilistic languages is found. The compact encoding of probabilistic languages is investigated. The concept of information losslessness is extended to the infinite automata. Four classes of Coding Automata are defined and their operations are explained. Optimality is discussed in the coding schemes as is the type of language of the output code. The average code length of the four classes is compared. (Author)
