A measurement of the electron charge asymmetry in p+→W production in association with jets at sqrt{s}=7 TeV is presented. The dataset corresponds to an integrated luminosity of L=5fb^-1 recorded by the CMS detector in proton-proton collisions at the LHC. The sample represents a large increase in statistical precision with respect to previous CMS results and describes a first study of charge asymmetry measured in p+p→W+1 jet events. Full comparisons to previous results and theoretical predictions are provided and recommendations for extending the analysis to produce valuable input for future PDF models are made.

During the past several years an increase in use of Course Management Systems (CMS) in higher education’s instructional infrastructure had been witnessed (Morgan, 2003). As a result, increased online education placed an emphasis on CMS because CMS were able to provide information 24 hours a day, 7 days a week. Faculty, staff, and students were increasingly dependent on information and learning services provided by the colleges and universities (Carey & Gleason, 2006). The flexibility provided by the CMS had led campus faculty, staff, and students to expect continuous availability in campus systems (Carey & Gleason, 2006). This study examined faculty perceptions of a course management system used to enhance teaching and learning. Faculty members’ perceived motivation reasons and barriers were analyzed in this study using descriptive statistics. The important motivation reasons for using a course management system were to provide course information, augment student learning, and provide diverse teaching methods. In addition, the study revealed that faculty members were satisfied with institutional support in terms of training and technical support but not rewards received. Demographic variables (gender, age, faculty tenure status, faculty rank, college of teaching, location of course delivery, and time spent per week preparing materials) were examined to see if there were differences in faculty members’ perceived satisfaction of pedagogical effectiveness. An online survey was sent to 300 faculty members who used CMS in their academic courses at Mississippi State University. Descriptive statistics were used to analyze the survey data. The results revealed that the majority of faculty used CMS primarily to: (a) distribute information to students, (b) augment student learning and (c) provide diverse teaching methods. In terms of strengths and weaknesses of a CMS some faculty members thought the tools were complicated to use while others thought it was easy to use. Overall, the majority of faculty thought that CMS was a great way to communicate with students. Faculty also thought that lack of time played a role in their ability to use CMS effectively.

<p>The top quark is the most massive known elementary particle, and plays a pivotal role in our understanding of particle physics. Its unique properties offer valuable insights into the Standard Model and potential hints for physics beyond the Standard Model. In this thesis we present a precision measurement of the polarization of top quarks and spin correlations between top-antitop (ttbar) pairs using Run-II datasets collected from the Compact </p> <p>Muon Solenoid detector at the Large Hadron Collider. In the first part of this thesis we introduce the theoretical framework of the Standard Model and its predictions regarding top quark spin polarization and ttbar spin correlations. Next, we describe the experimental setup, reconstruction techniques, and Monte Carlo simulations used in this research. Subsequently, details of the measurement, including event selection, top quark reconstruction, and unfolding are described. The analysis achieves exceptional signal purity and precision with respect to previous measurements. The measured values of coefficients are in agreement with Standard Model expected values as well as theoretical predictions at NLO in QCD. In a first, we provide provide double-differential cross sections of top quark spin polarizations and ttbar spin correlations, as a function of the invariant mass of the ttbar system. We expect the results from the final CMS publication to supersede any results presented in the measurement part of this thesis document. In the final section of this thesis, we present a projection study of top quark spin polarization and tt ̄ spin correlations at the upcoming High Luminosity LHC. We present projections of the fraction of SM-like events and show that the upcoming detector could reduce uncertainties by as much as a factor 2. An alternative to the SM scenario is also considered in the form of Super Symmetry, and it is shown that we can significantly increase the ultimate reach of the LHC to discover top squarks in the degenerate mass corridor in the top squark-neutralino plane, or in the absence of a discovery exclude top squarks up to 600 GeV. </p>

The purpose of this thesis was to evaluate the impact of dynamic message signs (DMS) on the Orlando-Orange County Expressway Authority (OOCEA) toll road network using the Pre-Deployment DMS Survey (henceforth referred to as "pre-deployment survey"). DMS are electronic traffic signs used on roadways to give travelers information about travel times, traffic congestion, accidents, disabled vehicles, AMBER alerts, and special events. The particular DMS referred to in this study are large rectangular signs installed over the travel lanes and these are not the portable trailer mount signs. The OOCEA is currently in the process of adding several fixed DMS on their toll road network. Between January 2007 and February 2008, approximately 30 DMS are planned on their network. It is important to note that there was one DMS sign on the OOCEA network before this study started. Since most of the travelers on OOCEA toll roads are from Orange, Osceola and Seminole counties, this study is limited to these counties. This thesis documents the results of pre-deployment analysis. The instrument used to analyze the travelers' perception of DMS was a survey that utilized computer aided telephone interviews. The pre-deployment survey was conducted during early November of 2006. Questions pertaining to the acknowledgement of DMS on the OOCEA toll roads, satisfaction with travel information provided on the network, formatting of the messages, satisfaction with different types of messages, diversion questions (Revealed and Stated preferences), and classification/socioeconomic questions (such as age, education, most used toll road, and county of residence) were asked to the respondents. The results of the pre-deployment analysis showed that 54.4% of the OOCEA travelers recalled seeing DMS on the network. The respondents commonly agreed that the DMS are helpful for providing information about hazardous conditions, and that the DMS are easy to read. The majority of the travelers preferred DMS formats as a steady message for normal traffic conditions, and use of commonly recognized abbreviations such as I-Drive for International Drive. The results from the binary logit model for "satisfaction with travel information provided on OOCEA toll road network" display the significant variables that explain the likelihood of the traveler being satisfied. The results from the coefficients show that infrequent travelers are more likely to be satisfied with traveler information on OOCEA toll roads. In addition, the provision of hazard warnings, special event information, and accuracy of information on DMS are associated with higher levels of satisfaction with traveler information. The binary logit model for "Revealed Preference (RP)" diversion behavior showed that Seminole County travelers were likely to stay on the toll road, and SR 408 travelers were likely to divert off the toll road. The travelers who acknowledged DMS on the OOCEA network were also likely to divert off the toll road, but those who learned of the congestion by DMS were likely to stay on the toll road. Learning of congestion by DMS could encourage travelers to stay, since when they are on the toll roads, diversion at times could be difficult with no access to exits or little knowledge of alternate routes. But it is also possible that travelers stayed because their perception was that the toll roads are faster, especially when messages on DMS show travel times that confirm the travelers' belief. Travelers who were not satisfied with travel information on the network were more likely to divert off the toll road. The implications for implementation of these results are discussed in this thesis. DMS should be formatted as a steady message for normal traffic conditions. Commonly recognized abbreviations, such as I-Drive for International Drive, must be used for roadway identification when possible. DMS messages should be pertained to information on roadway hazards when necessary because it was found that travelers find it important to be informed on events that are related to their personal safety. Accuracy of information provided on DMS was important for traveler information satisfaction because if the travelers observe inaccurate travel times on DMS, they may not trust the validity of future messages. DMS information that led to the travelers canceling their intended stops led to a higher likelihood of them being dissatisfied with traveler information. It is important to meet the travelers' preferences and concerns for DMS.

A Lei nº 13.146 - Lei Brasileira de Inclusão da Pessoa com Deficiência (Estatuto da Pessoa com Deficiência) – que passou a vigorar a partir de janeiro de 2016 reforça a obrigatoriedade de acessibilidade nos websites mantidos pelo governo, estabelecida há mais de dez anos através do Decreto nº 5296/2004. Através do e-Gov, o governo tem empreendido várias ações no sentido de impulsionar o desenvolvimento de websites que atendam os mais diversos cidadãos, permitindo assim, o acesso às informações e serviços públicos com igualdade e sem discriminação. Dentre essas ações destacam-se as recomendações do Modelo de Acessibilidade em Governo Eletrônico (e-MAG) e o projeto Padrões Web em Governo Eletrônico (e-PWG). Neste contexto, os portais web das Universidade Federais têm grande responsabilidade de tornar acessível o seu conteúdo e informações a toda a comunidade. Este trabalho apresenta os resultados da avaliação da acessibilidade das páginas iniciais das 63 Universidades Federais Brasileiras. Como o uso de Sistemas de Gerenciamento de Conteúdo (CMS, do inglês Content Management System) para a construção de websites governamentais é uma recomendação destacada pelo e-PWG, esta pesquisa buscou ainda investigar se estas Universidades estão adotando esta tecnologia. Diante desses resultados, o objetivo foi identificar se o uso de CMS pode contribuir ou não com a criação de páginas mais acessíveis, destacando os principais problemas de acessibilidade encontrados por essas páginas. / The Law nº. 13,146 - Brazilian Law of Inclusion of People with Disabilities (Person Statute with Disabilities) - which came into effect from January 2016 reinforces the requirement of accessibility on websites maintained by the government, established for over ten years through the Decree No. 5296/2004. Through the e-GOV, the government has undertaken several actions to boost the development of websites that attend the most diverse citizens, thus allowing access to information and public services equally and without discrimination. Among these actions highlight the Accessibility Model recommendations on Electronic Government (e-MAG) and the Web Standards in Electronic Government project (e-PWG). In this context, the web portals of the Federal University have a great responsibility to make available the content and information to the entire community. This study presents the results of the evaluation of the accessibility of homepages of the 63 Brazilian Federal Universities. As the use of Content Management Systems (CMS) for the construction of government websites is a recommendation highlighted by e-PWG, this research has also sought to investigate whether these universities are adopting this technology. Given these results, the goal was to identify the use of CMS can contribute or not to create more accessible pages, highlighting the major accessibility problems encountered by these pages.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / O Compact Muon Solenoid (CMS) é um dos principais detectores instalados no LHC que possibilita o estudo de diferentes aspectos da Física, indo do Modelo Padrão à matéria escura. Esse detector de propósito geral, foi construído para ser capaz de medir múons com uma grande precisão e todos os seus subdetectores foram construídos com uma alta granularidade, tornando possível identificar e caracterizar as propriedades cinemáticas das partículas finais da colisão. O algoritmo de reconstrução de eventos inclui a identificação de jatos, ou seja, é possível identificar a assinatura da produção de pártons na colisão e a medida de seções de choque da produção de muitos jatos é um dos métodos para se explorar as contribuições da Cromodinâmica Quântica (Quantum Chromodynamics - QCD) perturbativa, permitindo avaliar as previsões implementadas nas simulações de eventos. Tendo em vista a caracterização de processos relacionados com a QCD em colisões de próton-próton a uma energia do centro de massa de 7 TeV, é apresentada a medida da seção de choque da produção inclusiva de multijatos no CMS. Para realizar essa medida foram utilizados dados reais coletados em 2010, onde não se apresentava muitas colisões por cruzamento de pacote, com uma luminosidade integrada de L = 2,869 pb-1 e utilizando jatos que estão em quase todo o espaço de fase acessível em pseudorapidez |n|&#8804; 4,8 e momentum transverso pT &#8805; 30 GeV/ c2. Desse resultado foram removidos os efeitos de detecção comparado com predições simuladas. / CMS is one of the main detectors installed in the LHC that is able to study different physical aspects, from the Standard Model to dark matter search. This general purpose detector was constructed to measure muon properties with high precision and all subdetectors were built with high granularity making possible to identify and characterize the kinematic properties of all final stable particles. The event reconstruction algorithm includes the jet identification, in other words, it is possible to identify the signature of parton production in the collision. The measurement of the cross sections of multijet production is one of the methods to explore perturbative QCD contributions, allowing the evaluation of the predictions implemented in the event simulation. Focusing on the characterization of the QCD related process in proton-proton collision at &#8730;s = 7 TeV , the measurement of the inclusive multijet production in CMS is presented. The measurement is done using real data with low pileup events collected in 2010 with integrated luminosity of L = 2,869 pb-1 and using jets in almost all pseudo-rapidity accessible range |n| < 4,8 and low transverse momentum pT > 30 GeV/c2. The detector effects in the measurement was removed, called unfolding procedure, and compared with Monte Carlo predictions.
