This study was undertaken to compare the response of three dosimeters to different environments. Comanche Peak Nuclear Power Plant wants to replace the current badge of record. The RaDos DIS-1 direct-ion storage dosimeter (DIS-1) and the Landauer InLight optically stimulated luminescence dosimeter (OSL) are the two candidates for replacement of the Panasonic UD-802 thermoluminescence dosimeter (TLD). The dosimeters were compared in five categories: dose linearity, dose-rate linearity, fade response, humidity response, and the angular dependence of the dosimeters. The major results include verified linear relationship evidence for dose and doserate and a better fade response for both the DIS-1 and OSL. The TLDs faded by 9.2% over a month and the DIS-1 and OSL faded by 4.2% and 1%, respectively. Following a dose of 557.5 mrem, the dosimeters were exposed to different relative humidites. The dose to the DIS-1 and OSL did not change drastically while the TLDs dose readout was reduced by 10%. Finally, the angular dependence of the dosimeters was compared and the worst responses were 66% at 90° in the horizontal orientation for the OSL and 1.7% at 90° in the horizontal orientation for the DIS-1. Based on the results of these tests the OSL seems like a more viable candidate for the new badge or record.

ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California / When developing a video compression system in black box for aircraft, it is necessary to consider the characteristic of the images and the surrounding environment. The images captured in and out of aircraft have excessive movement-related issues, which make the results difficult to analyze and interpret. Failure to remove the tremors in the video component inevitably leads to poor compression efficiency and degrades the video imaging performance in the airborne black box. Therefore, it is necessary to develop a Compression System which can stabilize the video-image and efficiently utilize high compression recording for aircraft without special hardware. Based on the current situation, we suggest a real-time electronic video stabilization algorithm for airborne recorder which recovers shaky images simply and efficiently to work beside a developed stabilization system based on the H.264 Encoder using DSP.

Autoethnography is a research method that relies on connecting personal narrative to larger social issues, using writing and/or performance to draw those connections for an audience and critique those issues along the way. Autoethnographers, in a vulnerable act, tell their own stories to make these connections and critiques, and ask their audiences to help them change the way society functions, to help achieve social justice by engaging with and helping to solve these issues. This project explores a specific autoethnographic work—The Wolf Inside, a solo performance piece dealing with the dis/ableist experiences of the author in their journey toward diagnosis, treatment, and good quality of life with systemic lupus erythematosus. It examines the implications of autoethnography as a method of educating audiences about invisible disabilities like lupus, confronting harmful dis/ableist behaviors, offering solutions to these issues, and functioning as a coping mechanism for the author/performer who lives with invisible disabilities.

PREOP is a medical expert system which is being developed on the expert-system shell NEXPERT. PREOP determines the risk of cardiac complications for a patient about to undergo noncardiac surgery, and recommends a programme of medication intake for the patient. PREOP's final database and hardware requirements are uncertain, and so are its final functionalities. These uncertainties necessitate a database interface which facilitates overall system flexibility, maintainability, modularity, and integration with existing information systems. These objectives are best achieved by a loosely coupled database interface which is not under NEXPERT's control. PREOP-DIS is a loosely coupled database interface system for PREOP. This project uses the relational model to design PREOP' s database and implements the database on the relational DBMS SYBASE. The project implements PREOP-DIS as a C program that communicates data between PREOP and the SYBASE database by dynamically making calls to NEXPERT and to the SYBASE dataserver. / Thesis / Master of Science (MS)

Neste trabalho nós abordamos dois temas da QCD em altas energias. A distribuição nuclear de glúons e a saturação de pártons. As parametrizações da distribuição nuclear de glúons disponíveis atualmente na literatura são bastante diferentes entre si, o que mostra que esta distribuição ainda é bastante incerta. Nós mostramos que é possível vincular a distribuição de glúons no núcleo em altas energias a observáveis nucleares inclusivos, o que facilitará a distinção entre as diferentes parametrizações quando surgirem novos dados experimentais destes observáveis. O segundo tema abordado, a saturação de pártons, é uma questão muito importante atualmente, e a existência ou não deste fenômeno poderá ser definitivamente confirmada no LHC e no futuro eRHIC. No caso da saturação nós mostramos que os observáveis inclusivos não serão úteis para indicar se ocorre ou não a saturação de pártons em altas energias. Nossa conclusão foi a de que para os efeitos da saturação, ao invés destes observáveis devemos nos concentrar nos observáveis difrativos, que são muito mais sensíveis a dipolos de grande tamanho e corresponderão a uma fração significativa dos eventos observados. / In this work we considered two subjects of QCD at high energies. The nuclear gluon distributions and the parton saturation. The currently available parametrizations of nuclear gluon distribution in the literature are very different among themselves. We show that it is possible to relate the gluon distribution in a nucleus at high energies to nuclear inclusive observables. This will allow us to distinguish between the different parametrizations when new experimental data become available. The second subject considered, parton saturation, is currently very important, and the existence or not of this phenomenon will be confirmed at the LHC and at the future eRHIC. In the case of saturation we show that inclusive observables are not very useful to indicate if parton saturation occurs at high energies. Our conclusion was that to detect saturation effects, instead of these observables we must focus on the diffractive observables, which are much more sensitive to big dipoles and will correspond to a significant fraction of the observed events.

Le développement de nouveaux antibiotiques est un enjeu majeur de santé publique. Etant donné, le fort potentiel des aminoglycosides en tant qu’antibiotique, ces composés ont attisé l’intérêt de plusieurs groupes de recherche. Cependant, leur usage est encore très limité, malgré leur ancienneté, du fait de leur toxicité et du développement toujours croissant des mécanismes de résistances aux aminoglycosides. Afin de mieux appréhender les problèmes inhérents à leur utilisation, il est crucial de mieux comprendre leur action sur les différentes cibles cellulaires, et d’étudier leur interaction avec leur cible moléculaire (ARN et protéine). En plus de leur pouvoir antibiotique, les aminoglycosides sont également des ligands universels pour des ARN, capables d’interagir spécifiquement avec notamment les ARN du VIH-1 suivants : DIS, TAR, RRE. L’élaboration d’aminoglycosides modifiés présente un énorme avantage car le domaine d’application, et en conséquence les retombées, sont grandes. Néanmoins, la complexité structurale de ces molécules est un frein majeur, la fonctionnalisation chimiosélective est indispensable mais malheureusement peu décrite dans la littérature. Dans le cadre de ce travail, nous avons développé deux types d’approches pour cibler le DIS et/ou le site A du ribosome bactérien. La première originale, mais risquée se base sur le concept de click in situ. La seconde approche est traditionnelle et est basée sur la fonctionnalisation sélective de certaines positions clés des aminoglycosides. / The development of new antibiotics is a major public health issue. Given the high potential of aminoglycosides as antibiotics, these compounds have aroused great interest in many research groups. However, despite their maturity, their use is still limited because of their toxicity and the increasing development of resistance mechanisms to aminoglycosides. To better understand the problems inherent to their use, it is crucial to understand their action a cellular level, and to study the interactions with their molecular targets (RNA and protein). In addition to their antibiotic power, aminoglycosides are also universal ligands for several RNAs, capable of specific interactions with RNAs of HIV-1: DIS, TAR and RRE. The elaboration of modified aminoglycosides presents a huge advantage because the domain of application, and therefore the benefits, are important. Nevertheless, the structural complexity of these molecules is a major constraint, chemoselective functionalization is essential but unfortunately poorly described in the literature.In this work, we developed two approaches to target the DIS and/or the A site of the bacterialribosome. The first one, unique but challenging is based on the concept of in situ click chemistry. The second approach is conventional and is based on the selective functionalization of some keypositions of aminoglycosides.

Syftet med denna studie är att undersöka elevernas berättelser när det kommer till deras övergång mellan förskola och förskoleklass. Att pedagogerna skapar rätt förutsättningar med trygghet för barnen när de ska göra övergången från förskola till förskoleklass och bli elever. Studien är kvalitativ och metoden som användes var semistrukturerade intervjuer. Vid 4 tillfällen genomfördes semistrukturerade gruppintervjuer med elever från två olika förskoleklasser och de ligger i samma kommun. Den insamlade datan är transkriberad och analyserad utifrån det sociokulturella perspektivet med inriktning på den sociala och fysiska kontinuiteten och diskontinuiteten. Tolkning av resultatet i denna studien visar att en viktig del är kompisarna i samband med en övergång.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The Distributed Interactive Simulation (DIS) concept, since its inception, has been defined into three separate but distinct areas of service. • Viewing of data in the real-time environment. • Multiple range viewing and usage of"real-time data." • Problems with the sharing of information through DIS. This paper will discuss the DIS concept and some of the various methods available to display this data to users of the system.
