This dissertation draws on twenty-four months of fieldwork at Biocurious, a "garage lab" in Silicon Valley expressly designed to democratize science, and a self-described "new thing in the world." From that starting point, this dissertation poses the following questions: a) how does a "garage lab" come to be recognized as a "garage lab," and b) what kind of scientist works to what effect inside a "garage lab." These questions are taken up on two levels: theoretically through a critical engagement with anthropological approaches to design, an explication of the difficulties and paradoxes inherent in the relationship between expertise and democracy, and through the business of producing an audience for and presenting "new things in the world" to the public, also found in precursors such as Thomas Edison and P.T. Barnum. Empirically, these questions are taken up as a particular problem for a group of people in Silicon Valley as they go about the everyday work of making a "garage lab" and deliberating among themselves and their consociates over its perils and possibilities. Ethnographically, this dissertation is animated by my participation initially as a volunteer, then as a member of the "garage lab," and finally through my participation as a member of a community project at Biocurious. Theoretically, this dissertation furthers Flusser's (1999) theory of design as "a trick against nature [the given]" by pulling it tight to the traditional anthropological concern with cultural production and critically examines the claim to democratization, finding the claim to democratization at Biocurious a reordering rather than erasing the hierarchy of expertise. Finally, the dissertation considers the afterlife of "new things in the world," which fade into the background as they inevitably move from the made (cultured) to the given (natural) Following the text are two appendixes. Appendix One addresses the folklore of the modern laboratory by examining instructional stories told at the "garage lab," the unicorn in Silicon Valley, and the signs of domestic life in the "garage lab." Appendix Two constitutes notes towards a mechanical model that can account for the life of "new things in the world," as they inevitably form for the basis for further cultural productions.

O presente trabalho tem como estímulo inicial uma pesquisa desenvolvida pelo Professor Doutor Antonio Luiz Dias Januzelli e a doutoranda Juliana Jardim que entre os anos de 1999 e 2000, coletaram em forma de entrevista experiências e vivências práticas de oito professores profissionais de teatro, objetivando tornar público os seus procedimentos e suas práticas centradas na formação do ator contemporâneo em São Paulo. Este presente trabalho se propôs investigar quatro destes depoimentos, a saber: Cristaine Paoli-Quito, Luiz Damasceno, Márcio Aurélio e Myrian Muniz, cruzando suas práticas, avaliando conteúdos convergentes e divergentes nos diferentes processos assim como desenvolver uma possível sistematização orgânica unificada desses conteúdos. / The present work has as initial stimulus a research developed by Doctor Professor Antonio Luiz Dias Januzelli and the graduate student Juliana Jardim that between 1999 and 2000, interviewed eight professors and theatrical professionals with the objectives of publication their proceedings and their practical approaching and training of actors at São Paulo. This present work took four interviewed pronouncements such as: Crisitane Paoli Quito, Luiz Damasceno, Márcio Aurélio e Myrian Muniz and tried to cross their practical work, analyzing the similarities and differences of their jobs and also build a possible unified system characterized by their contents.

A 300 hp motor and generator testing facility is being completed at Oregon State University. The testing center is the largest independent testing facility west of the Mississippi River. This regional resource center will incorporate state-of-the-art features that set it apart from other testing facilities. An induction machine with a modem regenerative power electronic converter is being used as the dynamometer. This regenerative dynamometer system significantly reduces the amount of power necessary for testing, allows for extremely flexible computer controlled testing, and is able to test adjustable speed machine systems from 100-4000 r/min. The dynamometer system is able to fully test both motors and generators of 240 hp from no-load to 125% rated load. A virtual instrumentation system provides tremendous flexibility and measures instantaneous, rms, and spectral signal values. Because the system is designed for testing over a wide speed range, it is necessary that all dynamometer losses are isolated and tabulated for the entire speed range. Initial fixed speed testing was performed on a 60 hp induction motor and standard report formats were generated for this and future test center use. The results were compared to the manufacturer's original testing data. To demonstrate the ability to test generators by using the dynamometer as a prime mover, a set of tests were also performed on a synchronous machine in accordance with IEEE standards. / Graduation date: 1996

The major work involved is the development of a practical and reliable radiocarbon dating laboratory at Ball State University. The method involved in determining the age of an organic sample, such as wood, peat, bone, or shell, is a carbon to benzene conversion procedure, followed by a liquid scintillation counting technique. The procedure involves producing; lithium carbide at 9000 C from our carbon sample, and then adding distilled water at room temperature to generate acetylene gas. Using a vanadium pentoxide on alumina catalyst, the acetylene is trimerized to benzene. The benzene is used in the liquid scintillation counter to determine the radiocarbon content. The age of a sample is then calculated from the ratio of carbon-14 to carbon-12, as found through the counting technique.Ball State UniversityMuncie, IN 47306

A new hardware system for the ECE 4550 Control System Design lab is proposed. The current hardware is examined and its shortcomings are documented. Design guidelines for the new system are put forth and interfaces between hardware elements are defined. Four hardware elements are developed: a motherboard, an I/O daughtercard, a DC motor driver daughtercard, and an AC motor driver daughtercard. Each of these systems is examined in depth from a design decision standpoint as well as from the standpoint of the design guidelines promulgated earlier. Technical limitations for each system are disclosed and examined in detail.

The process of computerised tomography (CT) has been developed for medical imaging purposes using a variety of X-ray scannars. So far, little attention has been paid to industrial applioaticns of this technique, largely because of the constraints of expense. An investigation was made of the suitability of one medical scanner, the EMI CT5005, as an industrial scanning tool. This showed up a variety of problems when scanning non-medical objects, and suggested an alternative approach to the problem. This was to construct an experimental scanner based on gamma-ray sources, to overcome the problems of beam hardening,, and provide versatility and, perhaps, portability. The greatest limitation on this sort of device is the time needed to produce a scan. However, even with small laboratory sources it seemed possible to produce a usable scanner. This experimental scanner was constructed and developed to the stage of producing very acceptable images, albeit of moderate resolution. This thesis outlines the basic theory of reconstructing images using CT, and describes the considerations leading to the development of the experimental scanner. The scanner itself is described, along with details of control, data processing, and the problems encountered. The statistical limitations on the scanner are described, and the way these affect the quality of the final CT image is investigated in detail. A variety of applications of the scanner are suggested, both in its present form and with foreseeable development, and a catalogue of the scans obtained using the scanner is provided.
