Widespread adoption of phased array technologies has been hindered primarily by the high cost associated Transmitter/Receiver (T/R) modules. In conventional phased arrays, these vital elements often comprise up to fifty-percent of the entire array's expense. Recent development of a new type of phased array - the Electronically Steerable Passive Array Radiator (ESPAR) - is underway at laboratories around the globe. This innovative concept utilizes mutual coupling to excite neighboring (passive) elements placed in the near field of a center-driven (active) radiator. Using this method, T/R modules are only required for the active radiators. The radiation pattern of an ESP AR is controlled electronically by means of variable reactive loading of the passive antenna elements. In order to attain the full range of beam steering offered by this array, a broad range of reactance is required at the input port of each passive antenna. This thesis presents a varactor-based reactive network design that can accurately and reliably produce a wide range of reactance. The purpose of this research was to design a network compatible with the requirements of the ESP AR phased array, which is in development at the Antennas, RF, and Microwave Integrated Systems CARMI) laboratory at the University of Central Florida. To this end, an elaborate survey weighing different varactor-based reactive network and DC bias tee designs was conducted. This study took into account the practical issues and limiting factors that arose during design and implementation of such a network. While this specific network design was constrained to operate at 3 GHz, the proposed design methodology may be applied to realize reactive networks at other frequencies. This flexibility allows incorporation into similar ESPAR's and a plethora of other relevant devices.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Bioimpedance (BIA) is a method that applies the impedance of technology in the study of body composition by evaluating the difference of electric conductivity of the tissues. The BIA results are expressed by primary measures resistance (R) and reactance (Xs). The study aimed to propose equations that can estimate the chemical and tissue carcass components using in vivo BIA in lambs slaughtered at different slaughter weights. The experiment was conducted at sheep breeding laboratory of the Universidade Federal de Santa Maria, Santa Maria, RS. Were used 31 uncastrated lambs, crossbreed Texel versus Ile de France, with about age 3 months and 19.7 kg of average live weight. Lambs were feedlot fed ad libitum with a standard diet.The predefined slaughter weights were 20, 26, 32 and 38 kg live weight . A day before the slaughter was made in vivo assessments and, after 14 hours fasting were made in vivo BIA measurements. It was used monofrequencial apparatus, alternating current generator of 50 kHz and 800 uA. This device has 4 electrode terminals. The electrode placement were on the animal right side, on the ventral region, 10 cm between the electrodes transmitters and receivers. The electrodes used were acupuncture needles. After slaughter were made assessments on carcass. In the right half carcass were made deboning to obtain the tissue and chemical components. Correlation analyzes were used to determine the variables included in the regression analyzes. Multiple regression analysis with stepwise control were performed using the carcass components as dependent variables and measurements from in vivo assessments, in vivo BIA, carcass assessments and their combinations as predictors parameters. The resistive density (DRs) and reactive density (DXc) bioelectric volume (V) and phase angle (AF) were the best BIA variables correlated to carcass body constituents. The prediction equations using measurements BIA showed R2 0.84 and 0.93, for bone and soft mass (kg), respectively. R2 0.73, 0.84, 0.87 and 0.91, respectively, ash, moisture, lipids and protein (kg). And R2 0.76, 0.89 and 0.90 respectively to lipids protein ratio, soft mass without fat and lean body mass (kg). The BIA in vivo has good potential to estimate chemical and tissue carcass composition of lambs slaughtered at different slaughter weights. The BIA was more accurate estimating the absolute body components than percentage carcass components. / A bioimpedância (BIA) é um método que aplica à tecnologia da impedância no estudo da composição corporal pela avaliação da diferença da condutividade elétrica dos tecidos. Os resultados da BIA são expressos pelas medidas primárias de resistência (Rs) e reatância (Xs). O estudo teve como objetivo propor equações que possam estimar os componentes químicos e teciduais da carcaça, com o uso da BIA in vivo, em cordeiros abatidos com diferentes pesos de abate. O experimento foi conduzido no Laboratório de Ovinocultura da Universidade Federal de Santa Maria, Santa Maria, RS. Foram utilizados 31 cordeiros machos não castrados, da raça Texel versus Ile de France, com aproximadamente 3 meses de idade e peso vivo médio de 19,7 Kg. Os cordeiros foram confinados e alimentados ad libitum com uma dieta padrão. Os pesos de abate predefinidos foram 20, 26, 32 e 38 Kg de peso vivo médio. Um dia precedente ao abate foram feitas avaliações in vivo e, após jejum de 14 horas foram feitas as mensurações da BIA. Foi utilizado o aparelho monofrequencial, gerador de corrente alternada de 50 kHz e 800 μA. Este aparelho apresenta 4 terminais de eletrodos, técnica tetrapolar. Os locais de colocação dos eletrodos foram no lado direito do animal, na região ventral a 10 cm entre os eletrodos emissores e receptores. Os eletrodos utilizados foram agulhas de acupuntura. Após o abate foram feita avaliações na carcaça. Na meia carcaça direita foram feitas a desossa para obtenção dos componentes teciduais e químicos. Análises de correlações foram usadas para determinar as variáveis inclusas nas análises de regressão. Análises de regressão múltipla com o comando Stepwise foram realizadas usando os componentes da carcaça como variáveis dependentes e as mensurações de avaliações in vivo, da BIA in vivo, avaliações na carcaça e suas combinações como parâmetros preditores. A Densidade Resistiva (DRs) e Densidade Reativa (DXc), Volume Bioelétrico (V) e Ângulo de Fase (AF) foram as variáveis da BIA melhor correlacionadas com os constituintes corporais da carcaça. As equações de predição utilizando mensurações da BIA demonstraram R2 0,84 e 0,93, para ossos e massa mole (Kg), respectivamente. R2 0,73, 0,84, 0,87 e 0,91, respectivamente, para cinzas, umidade, lipídeos e proteína (Kg). E R2 0,76, 0,89 e 0,90, respectivamente para a relação gordura proteína, massa mole sem gordura e massa corporal sem gordura (Kg). A BIA in vivo tem bom potencial para estimar a composição química e tecidual da carcaça de cordeiros abatidos em diferentes pesos de abate. A BIA mostrou-se mais precisa na estimativa dos componentes corporais absolutos que os componentes relativos da carcaça.

The purpose of this study was to better understand the goal-striving process in the context of non-problem gambler’s responsible gambling. More specifically, the primary aim of this study was to elucidate the hierarchical structure of goals, the role of the motivational phase of the goal-striving process, and the influence of cognitive evaluation and affective regulation on the goal-striving process. In the first part of the study, a conceptual model is proposed, in which the intrinsic factors used to predict non-problem gamblers’ intentions to gamble responsibly are delineated and tested according to the extension of the theory of planned behavior (Ajzen, 1985, 1991), the model of action phases (Gollwitzer, 1990, 1993), the model of goal-directed behavior (Perugini & Bagozzi, 2001; Perugini & Conner, 2000), and the model of effortful decision making and enactment (Bagozzi, Dholakia, & Basuroy, 2003; Dholakia, Bagozzi, & Gopinath, 2007). Four cognitive factors explain the motivational phase of the goal-striving process, and were incorporated in the current study. One factor explains the goal-oriented behavior at abstract level (i.e., goal feasibility), and the other three explain implementation of action-oriented behavior at concrete level (i.e., attitude toward implementing the actions necessary to achieve the goal, subjective norm, and perceived behavioral control). In addition, two ways of emotional regulation were incorporated to explain the goal-oriented behavior at abstract level. That is, prefactual emotional valence factors related to the success and failure of future goal attainment (anticipated positive and negative emotions) affect goal desire. To sum up, this study anticipated that the proposed antecedent constructs (two anticipated emotions, goal feasibility, attitude, subjective norm, and perceived behavioral control) were strong indicators of how non-problem casino patrons would strive to achieve the goal (i.e., maturing or developing responsible gambling behavior) through a goal-striving process, where the motivational phase plays a critical role in explaining intention to gamble responsibly. A secondary goal of the study was to explore how responsible gambling strategies implemented by the gambling industry influence non-problem casino customers’ goal-directed behavior in a responsible gambling setting. Given the ongoing controversy about the effectiveness of responsible gambling strategies, the focus in the second part of the current study was on how situational arousal factors (i.e., psychological reactance) with regard to external interventions (i.e., compulsory and supplementary responsible gambling strategies) would affect implementation intention, based on the psychological reactance theory (J. W. Brehm, 1989; S. S. Brehm & Brehm, 1981). In other words, situational arousal factors were incorporated herein to explain the extrinsic part of the goal-striving process model. This study was designed to facilitate an understanding of how and why external interventions may fail to deliver the intended effect in the responsible gambling context. In order to take into account the varying effectiveness of responsible gambling strategies, an effort was made to discern between the different effects of each responsible gambling strategy type and to understand in greater detail how these effects were moderated by individual disposition, and especially the strength of the individual’s desire for control. A clear understanding of the moderating effect enables a richer understanding of the effectiveness of responsible gambling strategies with regard to responsible gambling behavior by non-problem casino patrons. Insight gained from the study through analysis of the results is discussed, and important theoretical and practical implications and future research agendas presented in the conclusion. / Tourism and Sport

一向強調使用者自主性的網路媒體，卻也出現插播式廣告(Interstitial)這種強迫閱聽眾接收的形式，這種情形引發了研究者的興趣。相較於傳統媒體，已經賦予閱聽人部分自主權的情形底下，廣告主又想藉由形式的操弄強迫閱聽人接收，這可能引起的負面態度相對傳統媒體來說可能更為嚴重。因此，本研究首先欲探討插播式廣告的使用是否有其他優點，例如強迫接收的形式，會吸引更多注意的緣故而留下較深刻的印象，而讓廣告主在可能導致閱聽人反感的風險下仍願意使用。其二，插播式廣告的使用是否必然引起閱聽人產生被迫收看的感受，以及察覺到廣告主意欲操弄的意圖，進而降低說服效果。換言之，插播式廣告能否藉由提供閱聽人娛樂價值，因而避免負面態度的產生。 結果發現，相對橫幅廣告來說，插播式廣告的確能吸引較多的注意，但並不會留下較深刻的記憶。其次，插播式廣告是否會引起操弄意圖推論、強迫性感受，進而降低說服效果，關鍵在於如果廣告能夠提供娛樂價值，那麼閱聽人並不會做出操弄意圖推論，也不會感覺到自己是被迫收看廣告的，當然不會進一步降低廣告態度。反之，若不提供其他價值，則會導致閱聽人做出操弄意圖推論，以及產生強迫性感受，因而進一步降低廣告態度。 最後，我們以一個交換的觀點來貫穿整篇文章，決定閱聽人是否產生操弄意圖推論或強迫性感受，關鍵在於閱聽人付出以及得到了多少價值，如果能讓閱聽人感受到自己所獲得的價值多過所付出的代價，那麼閱聽眾是會原諒行銷者的操弄。 / Comparing with other forms of media, the internet empowers audience with more freedom to choose what to see. However, it also emerged a new type of advertisement called, interstitial, which is commonly known as pop up. This kind of internet advertising forces audience to see advertisement whether they want or not. This phenomenon interests me to see what kind of effect this it will create for viewers., Since the audience once had the privilege to choose what they wanted to see, one of which is now seemed to be taken away from them, will this create negative feelings of the audience? Firstly I would like to know if there’re any advantages for advertisers to use this kind of internet advertising under the risk of disfavor. I postulates that interstitial may draw more attention and leave more impression than a banner does because of its format. Secondly, interstitial will not necessarily cause intrusiveness and inferences of manipulative intent (IMI), if the advertisement can provide other form values such as information or entertainment. The result supports my hypothesis partially. Firstly, interstitial does draw more attention than a banner. However, except for making people more impressed, no other difference has been found. Secondly, if interstitial contains entertaining value, it will not make audience feel intruded, IMI. ,and hostile attitude toward that advertisement. Whereas it will cause intrusiveness and IMI if the interstitial advertisement forces audience to see it without having any rewards. In this case it will reduce the advertising attitude in the audience. Finally, we can use an ‘exchange of ideas’ to sum up the main idea of this paper. The audience will devote their efforts and time to processing the given message, if the interstitial can reward the audience with more than what they pay for. They will also forgive the advertisers for manipulating them. The key to decide whether the audience feels intruded or knows of IMI depends on how much the audience give and receive.

O sistema eletroeletrônico convencional utiliza um inversor de frequência que transfere a potência ativa do nível de tensão e corrente CC para o nível compatível com a rede elétrica CA em frequência, tensão e sincronismo de fases. Já o desenvolvimento do projeto teve como parte experimental a utilização de indutores adequados com valores variáveis de 200 mH a 500 mH entre os painéis fotovoltaicos e a rede convencional. A tensão e a corrente máxima de CC foi de 29,6 V e a máxima possível foi de 20 amperes. Utilizou-se do princípio do casamento de impedâncias entre o painel fotovoltaico e o sistema de fornecimento de energia CA. Assim o painel fotovoltaico fornece somente potência ativa para a rede não interferindo no sincronismo. Na onda de tensão e corrente CA há uma pequena alteração no nível CA em relação a simetria do eixo dos tempos, dentro dos limites previstos para a rede convencional de energia. Logo evidencia-se o fornecimento de potência ativa para a rede CA. Os resultados obtidos permitiram inserção na rede de cerca de 10% da potência ativa dos painéis fotovoltaicos, com a otimização dos valores dos indutores, ocorrendo a transferência de potência ativa dos painéis fotovoltaicos para a rede convencional de energia CA. / The purpose of this thesis is the design and development of a delivery system of electricity connected to the network without the use of complex electronic circuits. The electronics system uses a frequency inverter that transfers the active power level voltage and DC current to the level compatible with the mains AC frequency, voltage and phase synchronization. But the project was to develop experimental part the use of suitable inductors with variable values of 200 mH to 500 mH between the PV panels and the conventional network. The maximum current was 20 amperes. We used the principle of impedance matching between the photovoltaic panel and the power supply system CA. So the photovoltaic panel supplies only active power to the grid not interfering with the timing. In the wave of AC voltage and current for a small change in CA level against the symmetry axis of time. Logo is evident in the supply of active power to the grid CA. The results allowed inclusion in the network of about 10% of the active power of photovoltaic panels by optimizing the values of the inductors for the occurrence of power transfer of conventional photovoltaic panels for energy occurs CA.
