MEDUSA (Materials and Electronic Devices Universal System Analyzer) is a computer controlled automated workstation capable of conducting eight different experiments, under different independent parameters, and plotting twenty-eight different graphs representing basic semiconductor diode and transport characteristics. This thesis discusses the methodology of computer automation, and the development of the MEDUSA experimental test station. MEDUSA is divided into four different sections: a controlling batch file, a parameter selection routine (PARAMETER), an experimental running routine (RUNIT), and a data manipulation/plotting routine (GRAPHICS). MEDUSA conducts these eight experiments (capacitance and conductance versus time, voltage, current versus voltage, van der Pauw, and four-point resistivity) over a temperature range of 10-600K, with minimal operator interaction. The graphics routines, using elemental semiconductor equations, process the data, and plots high quality graphs suitable for publication. Device and material results are shown to substantiate the validity of this automated system. / Master of Science

This study investigates whether the social facilitation effect takes place when a person performs a computerized task that includes an animated intelligent agent (IA). The moderating effects of two individual differences, locus of control (LOC) and microcomputer playfulness (MCP), are tested for. It was proposed that an IA's presence would cause participants to exhibit this effect and that LOC and MCP would moderate a participant's arousal, measured as state anxiety, such that those possessing an internal LOC and those exhibiting high MCP would experience less arousal when performing computerized tasks with an IA present. Data was analyzed using a 2 (task difficulty) x 4 (intelligent agent) repeated measures MANCOVA. Most hypotheses are not supported, however MCP does appear to moderate arousal depending on the behavior of the IA.

[pt] Com o advento dos microprocessadores e a crescente diminuição do preço dos circuitos integrados LSI (Large Scale Integration) houve um aumento da utilização de computadores de pequeno porte para a realização de tarefas locais e especificas. Tornou-se, então, economicamente viável a utilização, em número cada vez maior, de redes interligando computadores de pequeno porte. O presente trabalho contém um estudo dos diversos problemas decorrentes do projeto de redes natureza, apresentando soluções adequadas a cada caso. / [en] Theappearance of microprocessors and the lowering costs LSI (Large Scale Integration) technology brought and increaase in the use of low-size computers for dedicated applications. So, it became economically feasible to interconnect such low-size computers, creating a network. A study of various problems arising from the design of such networks is presented, as well as adequated solutions for each case.

Approved for public release; distribution is unlimited. / This paper documents the development of a statistical analysis package for the TRS-80 microcoraputer. The package is comprised of six interactive programs which are generally divided into topical areas. The major emphasis is on exploratory data analysis and statistical inference, however, probability and inverse probability distributions are also included. The programming language is TRS-80 Level II BASIC enhanced by the input/output commands available through the ESF-80 (Exatron Stringy Floppy) mass storage subsystem. With the modification of these few commands, the package is compatible with most floppy disk operating systems designed for the TRS-80 Model I or Model III microcomputers. This statistical analysis capability implemented on a relatively inexpensive system provides a useful tool to the student or the trained analyst without ready access to a mainframe computer system. / Major, United States Marine Corps

This work deals with the design and implementation of Wi-Fi LED lighting. It consists of various modules - switches, buttons, single or multicolored light sources - and a central unit that provides mutual communication and automation. The result of the work is the design of a prototype and several modules, which are built on the basis of the microcontroller ESP32. Their utility is implemented in C++. The user interacts through the website. The main result of this thesis is a demonstration of the possibility of using Wi-Fi to control light sources and creating complex lighting using a combination of simple modules and rules.

The Linda programming language provides an architecturally independent paradigm for writing parallel programs. By designing and implementing Linda on a network of stand alone workstations a scalable multicomputer can be constructed from existing equipment. This thesis presents the design, implementation and testing of a distributable Linda kernel and communications subsystem providing a framework for full distribution of Linda on a network of workstations. Following a presentation of the Linda language, the kernel’s design and rationale are presented. The design provides for interprocess communications by implementing a protocol on top of the Unix socket facility. Choosing sockets as the interprocess communications medium has the advantage of wide portability. However, a design critique is presented which addresses several disadvantages of the socket based communications model. Considerable attention is given to quantifying the effectiveness of this design in comparison to a shared memory, non-distributable design from Yale University. A thorough investigation into the source of particular observed phenomena is presented which leads to an improvement in wall time performance of an order of magnitude. / Master of Science

This thesis is focused on the design of remote data transmission equipment, without access to mains power. The device will measure the voltage of the gas pipeline and send this information to the operator for processing. Analysis of today's technologies for long-distance transmission and based on the selected technology, the device will be designed. According to selected components, its power supply will be designed with the aim of long-term functionality and continuous operation.
