Resumo: Este trabalho teve como objetivo o desenvolvimento de uma microbomba de membrana acionada eletromagneticamente, tornando possível sua utilização futura em dispositivos que reúnam de maneira eficiente diversos processos microfluídicos. Para atingir este objetivo foi necessário o desenvolvimento do atuador, composto de uma membrana flexível e uma microbobina, e do modelo, aqui desenvolvido utilizando a técnica de grafos de conexão, que permita o planejamento futuro das aplicações deste dispositivo. A membrana flexível foi fabricada utilizando-se resina fotocurável de poliuretano-acrilato ou silício corroído em banho KOH e recebeu filmes de níquel puro, depositados por processo à vácuo e eletroquímico e filmes depositados eletroquimicamente da liga CoNiMnP. Tais membranas atingiram deslocamentos próximos a 1?m frente a campos magnéticos de aproximadamente 250 G. As microbobinas, produzidas por meio de deposição eletrolítica de ouro sobre alumina, foram capazes de gerar campos magnéticos ao redor de 50 G. A microbomba com câmara de bombeamento de 10 mm, fabricada com corpo em poliuretano-acrilato e com o atuador descrito apresentou um bom fluxo de líquido nos testes com água.
Abstract: This investigation was conducted to develop a new membrane micropump, magnetically actuated, able to be used in lab-on-a-chip devices. To reach this target, a new actuator was eloped, containing a microcoil and a flexible diaphragm covered with metallic film, and a bond-graph model, leading future applications planning. The diaphragm was made using photocurable polyurethane acrylate resin or silicon etched in KOH bath, covered with pure nickel films, deposited by sputtering and electroplating techniques and electroplated CoNiMnP films. Diaphragms reached 1 ?m displacement facing 250G magnetic fields. Microcoils, obtained by electroplating over alumina surfaces, produced magnetic fields close to 50G. Micropump pumping chamber diameter of 10 mm, made using polyurethane acrylate and using the described actuator produced good water flow in the tests

Повний текст джерелаThe objective of this work is to study the origins of the research related to risk and its implications to capital markets, including the Brazilian market. Important statistical characteristics, several basic probabilistic premises and the questioning of indiscriminate use of mathematical models developed by accountants and analysts in finances had been highlighted. There had been shown some kinds of statistical distribution which can be applied to capital markets. This research also presents characteristics of complex systems, Utility Theory, studied by Von Neumann and Morgenstern (1944), Efficient Markets Hypothesis (EMH), organized/systematized by Eugene Fama (1970), Limited Rationality, studied by Simon (1959), Behavioral Finance, dealt by Kahneman and Tveski (1979) and model\'s use by Merton (1994). In order to illustrate the work, there had been made an empirical study, contemplating Brazilian market and comparing it to Garbaix\'s (2003) results, obtained by American market study. This was made in order to verify the market return probability distribution to reinforce the importance of reflection in indiscriminate usage of models and its premises crack.

Resumo: O processo de secagem de sólidos induz efeitos colaterais no material seco, sendo que a redução de volume é um destes efeitos. O objetivo deste estudo é investigar as características do processo de encolhimento e propor uma estratégia para inclusão destes efeitos na simulação da secagem. Escolheu-se a banana como objeto de estudo devido a sua importância para o Brasil e à existência de alguns estudos sobre o encolhimento desta fruta. Estudou-se inicialmente o processo de encolhimento durante a secagem e os efeitos das condições de processo sobre o comportamento dimensional do material. Fatias de banana encolhem linearmente no início da secagem, mas esse comportamento não é observado para baixos teores de umidade. Como a banana possui uma estrutura potencialmente anisotrópica, o efeito do comportamento dos diferentes tecidos da fruta teve que ser levado em consideração através do estudo da transição vítrea de cada fase durante a secagem. Um dos tecidos, o mesocarpo, possui temperatura de transição vítrea de 46ºC quando seco e pode sofrer transição durante a secagem convectiva e afetar o volume final da amostra seca. Além disso, estudou-se como a umidade é compartimentalizada no interior de cada tecido pela técnica de RMN e a influência sobre o encolhimento da amostra. O mesocarpo é seco mais rapidamente, mesmo possuindo uma quantidade de umidade livre menor que o endocarpo. Finalmente, desenvolveu-se uma resolução de equações de balanço de massa e energia utilizando-se malhas não estruturadas para poder melhor adaptar o encolhimento na modelagem
Abstract: The drying process may induce collateral effects in the dry material, such as the volume reduction. The objectives of this study are to investigate the characteristics of the shrinking process and to consider a strategy for inclusion of these effects in a drying simulation. Banana was chosen as a case study due to its importance in Brazil and to the existence of some studies on the shrinking process of this fruit during drying. Initially the effects of the drying conditions on the dimensional behavior of the material were analyzed. Banana slices shrink linearly in the beginning of the drying process, though some deviation of this behavior is observed for low moisture content. As banana possesses a potentially anisotropic structure, the behavior of the different tissues from the edible fruit had to be taken into consideration through the study of the glass transition of each phase. One of the tissues, the mesocarp, has a glass transition temperature of 46ºC when totally dry and may undergo glass transition during convective drying, which affects the final volume of the dried sample. Moreover, moisture compartmentalization in the interior of each tissue was analyzed and related to the differential behavior during drying. The mesocarp is more easily dried even though it possesses a higher concentration of unbound moisture. Finally, a resolution of mass and energy balance equations using unstructured meshes in order to allow a better inclusion of the shrinkage effects in drying was developed.

Повний текст джерелаThis paper presents a first time application of a variant of the concepts underpinning the Fed Model, amalgamated with the Bond-Stock Earnings Yield Differential, by applying it to the dividend yields of REIT indices. This modification is termed the yield gap, quantitatively constructed and adapted in this paper as the Reverse REIT-Bond Yield Gap. This metric is then used as the variable of interest in a multivariate Markov regime switching model framework, along with a set of three regressors. The REIT indices trailing dividend yield and associated metrics are the FTSE/EPRA NAREIT series. All data are from Bloomberg Terminals. This paper examines 11 markets, of which the EMEs are classified as Brazil, Mexico, Turkey and South Africa, whereas the advanced market counterparts are Australia, France, Japan, the Netherlands, Singapore, the United Kingdom, and the United States. The time-frame spans the period June 2013 until November 2015 for the EMEs, whilst their advanced market counterparts time-span covers the period November 2009 until November 2015. This paper encompasses a tri-fold research objective, and aims to accomplish them in a scientifically-based, objective and coherent fashion. Specifically, the purpose is in an attempt to gauge the reasons underlying EMEs observed anomalies entailing reverse REIT-Bond yield gaps, whereby their tenyear nominal government bonds out-yield their trailing dividend yields on their associated REIT indices; what drives fluctuations in this metric; and whether or not profitable tactical asset allocation strategies can be formulated to exploit any arbitrage mispricing opportunities. The Markov models were unable to generate clear-cut, definitive reasons regarding why EMEs experience this anomaly. Objectives two and three were achieved, except for France and Mexico. The third objective was also met. The REIT-Bond Yield Gaps static conditions have high probabilities of continuing in the same direction and magnitude into the future. In retrospection, the results suggest that by positioning an investment strategy, taking cognisance of the chain of economic events that are likely to occur following static REIT-Bond Yield Gaps, then investors, portfolio rebalancing and risk management techniques, hedging, targeted, tactical and strategic asset allocation strategies could be formulated to exploit any potential arbitrage profits. The REIT-Bond Yield Gaps are considered highly contentious, yet encompasses the potential for significant reward. The Fed Model insinuates that EME REIT markets are overvalued relative to their respective government bonds, whereas their advanced market counterparts exhibit the opposite phenomenon.
