Full textO presente trabalho descreve o desenvolvimento de um gerador termoelétrico cujos termoelementos são obtidos a partir de um composto de dissiliceto de ferro (FeSi2). A originalidade do trabalho reside na simplificação do processo de obtenção do termoelemento e na utilização de matérias-primas com grau de pureza industrial, em contraposição aos processos usuais que utilizam materiais de custo elevado, com alto grau da pureza e sofisticados processos de fabricação. O composto é obtido pelo processo de fusão num forno de indução à vácuo. A forma geométrica do termoelemento é assegurada pelo processo de sinterização. Um processo de recozimento garante a formação da fase Beta, assegurando a existência das propriedades termoelétricas. O coeficiente de Seebeck mostrou-se dependente do tempo de recozimento. Para os materiais desenvolvidos, o termoelemento tipo P apresentou um coeficiente de Seebeck de 250 MV/K e o material tipo N, um coeficiente de 75 MV/K, valores estes que qualificam o material para construção de geradores termoelétricos. Estima-se que o custo de fabricação do material desenvolvido reduziu de oito para dois dólares o custo de fabricação de materiais termoelétricos por watt de eletricidade gerado. Experiências preliminares utilizando a técnica de serigrafia para fabricação de termoelementos parecem confirmar a possibilidade de uma redução ainda maior do custo de fabricação.
This work describes the development of a thermoelectric generator whose thermoelements are made of a new thermoelectric material, FeSi2, an iron disilicide alloy. The originality of this work relies on the simplicity of the process by which the termoelements are obtained and also on the possibility to use a raw material with industrial purity grade, as opposed to conventional techniques which use costly materials, with a high degree of purity, and sofisticated process of fabrication. The alloy is obtained by a process of fusion in a vacuum induction type furnace. The geometric shape of the thermoelement is obtained by a process of sinterization. An annealing process garantees the formation of the Beta phase, thus assuring the existence of thermoelectric propertyes. The Seebeck coefficient proved to be dependent on the time duration of the annealing. As for the material developed, the P Type material presented an average Seebeck coefficient of 250 MV/K and the N type material, a coefficient of 75 MV/K, these figures qualify the materials for construction of thermoelectric generators. It is estimated that the manufacturing cost of the material developed reduced the cost of thermoelectric materials per watt of electricity generated from eight to two dollars. Preliminary experiments using the silk-scream technique in manufacturing of thermoelements seems to promise an even greater reducting in the manufacturing costs.

Full textThe output characteristic of a photovoltaic (PV) module varies as the environmental conditions of the module’s operation change. Changes in operating temperature and incident sunlight dynamically change the maximum power available from a PV module, as well as the output voltage. The output voltage of the PV generating system must be regulated, in order to ensure proper power quality for connection to an electrical load, building electric power system, or the electric grid.
PV modules are typically connected in series strings and parallel arrays to create PV generating systems. Non-uniform environmental conditions create voltage mismatches throughout PV generating systems. A mismatch between module voltages can severely reduce the amount of power available from the overall generating system. These system losses can be eliminated by regulating the output voltage of each module.
This dissertation proposes a power electronic device that fulfills two objectives: extracting maximum power from the single PV module, and regulating the output voltage to ensure a constant value. This dissertation reviews the analytical design of such a system, and validates this design in simulation, utilizing MATLAB/SIMULINK and ANSYS Simplorer.

Full textO objetivo principal desta dissertação é o de buscar formas de modelar e controlar, adequadamente, condicionadores de ar de janela, pois tratam-se de máquinas que possuem um elevado consumo de energia, perdendo somente para o chuveiro elétrico. A contribuição do mesmo para a demanda do setor doméstico é da ordem de 7 %. As pesquisas de posse de eletrodomésticos mostram que somente 6 % dos domicílios têm instalada tal tipo de máquina, o que representa um expressivo potencial de crescimento para os próximos anos na aquisição deste produto. É oportuno observar que em edifícios comerciais, 48 % da energia é consumida com refrigeração, o que implica na necessidade de novos projetos em que centrais de grande porte sejam implantadas, visando um gasto comparativamente menor ao somatório de aparelhos individuais.
This work involves the modeling of window air conditioners, with the purpose to obtain the electrical potential consume by itself, related to the medium external temperature. To obtain such goal, it was necessary the study of all features which involve their several components, aiming the conduct fitted from the parts, due to the result expected. It was made a public research with the users from these equipments. From this result, it was developed a stochastic model to be used in energy demand from a specific region, considering that the equipment / machine in use shows similar qualifications. After that, it was added to the system of machine a direct load control, which delay the compressor, obtaining an efficient working from it (saving demand), without affecting deeply normal using conditions. Finally, comparing two examples mentioned above, it was concluded that in the less powerful equipment (air conditioner) the thermal control with changed features, had good results, while more powerful equipments are more economic with direct load control.

Power systems are undergoing major changes as more renewable energy resources are being deployed across their networks. Two of the major changes are the increase in direct-current (DC) generation and loads and making up for the uncertainty introduced by these resources. In this thesis, we have tackled these two important aspects; a DC power flow (PF) solver and an energy storage system (ESS) sizing under uncertainty. The three DC PF solvers proposed in this thesis exhibit complementary values and can handle a wide range of loads and generation types. We have also proposed a distributionally robust ESS sizing under model predictive control framework, capable of handling worst-case uncertainties.

Pour la première fois, une telle analyse est effectuée pour les modèles de matière noire qui embrassent les deux couplages élastiques et isospin-violation, ainsi que de la matière noire avec des interactions dépendant du dynamique et spin. En ce qui concerne les modèles considérés ici, nos résultats ne soutiennent pas une question d'interprétation sombre de données de détection directe soit dans la norme ou formalismes halo-indépendant.

Full textAs the LHC enters its second run at 13 TeV, new parameter space will become available that will allow for a more extensive search for supersymmetric partners. This thesis explores limits on a baryon number violating R-parity-violating (RPV) extension of the s-channel production of top squarks, examining the experimental signature for the R-parity conserving decay of the top squark into the lightest neutralino and a hadronically decaying top quark. Using Monte Carlo simulations I calculate upper bounds for the RPV coupling parameters λ'' for a range of top squark and neutralino masses that would allow for its existence.

Full textDirect bonding is a process by which two sufficiently flat and clean surfaces can bond to each other without any added adhesive layer. Direct bonding of patterned surfaces is often used for the fabrication of Micro-Electro-Mechanical Systems (MEMS), where a silicon wafer with cavities is bonded to a plain wafer. The fabrication of these devices is expensive and it would be useful to have guidelines when designing knew devices to know in advance if direct bonding will be possible.A 2D simulation model of the direct bonding of two substrates is developed and usedto study the influence of the cavities on the bonding wave velocity. The prediction of the simulation run with Comsol® are in good coherence with the experimental measures and a 2D law of the bonding velocity is obtained. The bonding of perfectly flat wafers with cavities should always be possible. Limitations to the bonding of real wafers are due to the elastic energy cost of deforming the non perfectly flat wafers. This limit is reached easily when the bonding wave must cross a trench, so a design with a small bonding guide to help cross the cavity will work best. The width of this wave guide should be chosen by considering the bow of the wafer. Indeed the second important design rule is to keep a bonding area big enough to have more adhesion energy than the elastic energy cost due to non flat wafers deformation.The adhesion energy is an important parameter of the direct bonding, as it is theenergy that drives the adhesion. This adhesion energy is different from the more widely known bonding energy which is the energy needed to separate two previously bonded wafers. In this work a simple method to measure the adhesion is proposed. Long time measurement of the evolution of the adhesion energy lead us to propose a mechanism for its evolution linked to the formation of capillary bridges between rough surfaces

Full textLowering the cost of wave energy conversion is an essential task for it to succeed as a future energy resource. In this work a converter, assumed cheaper than the regular back to back converter setting, have been investigated for a electric direct drive point absorber. Both experimental work and simulations are used in the analysis. In the experimental work, a permanent magnet generator with a 6-pulse diode rectifier, a DC-link and a DC/DC converter equivalent, was used. Steady state, dynamic and transient measurements were preformed and a simulation model was compared to the measurements. Good results were obtained and deviations were in general small, mostly +-3% for voltage and current measurements and +-8% for torque measurements. Based on transient measurements and simulations a general linearization of the system was made in order to obtain useful information about the system. A step up converter was used in the simulation and it demonstrated stable passive loading control. By using the information obtained by the linearization, the performance of the simulation model was improved by decreasing the DC-link capacitance. The modified simulation model had significant less torque ripple than the initial. The linearization model also can been used to identify time delay represented by the power take off unit in a wave energy converter. This will be done for a commercial size wave energy converter summer 2009.

Full textA bi-directional, direct conversion switch-mode converter is proposed for use in distributed household renewable energy systems. The converter is intended as the central interface between the household energy system’s low voltage Direct Current bus and the high voltage Alternating Current bus. The low voltage DC bus is connected to renewable generation and storage devices, while the high voltage AC bus is connected to the user’s equipment and the mains grid. The converter overcomes the inherent reverse-duty cycle problem associated with bi-directional converters by using a combination step-up / step-down half-bridge converter on the high voltage side of a high frequency transformer. The low voltage side of the transformer is driven by a full bridge inverter that acts as a rectifier during reverse mode. In order to control the flow of power in both directions the converter implements Average Current Mode Control. A method is developed to determine the transfer functions of common switch-mode converters by inspection alone. This method is applied to the proposed converter, and both current and voltage mode control loops are designed with the frequency response method. The control system is implemented using a Digital Signal Processor. A method of simultaneously simulating both the converter hardware and software is developed using VHDL. This method greatly reduced the development effort of the converter. The operation of the proposed converter is verified through this method of simulation. A prototype converter is constructed and successfully tested, thereby proving the viability of the proposed converter topology and control methodology.

Soil liquefaction during earthquakes is a phenomenon that can cause tremendous damage to structures such as bridges, roads, buildings, and pipelines. The objective of this research is to develop an energy-based approach for evaluating the potential for liquefaction triggering. Current procedures to evaluate liquefaction triggering include stress-based and strain-based procedures. However, these procedures have some inherent and potentially fatal limitations. The energy-based method proposed herein builds on the merits of both the stress- and strain-based procedures, while circumventing their inherent limitations. The proposed energy-based approach uses dissipated energy (or work) per unit volume to evaluate the potential for liquefaction. Because dissipated energy is defined by both stress and strain, this energy-based method brings together stress- and strain-based concepts. To develop this approach, a database of case histories in which liquefaction was either observed or not observed was assembled. Dissipated energy per unit volume associated with each case history was estimated and a family of relationships was regressed to define the amount of dissipated energy required to trigger liquefaction. Results from a series of cyclic laboratory tests performed on samples of sand were reconciled with the field-based relationships using a consistent definition of liquefaction. This research proposes a method that is based on a robust mechanistic framework that will make it easier to evaluate liquefaction for circumstances that are not well represented in current liquefaction evaluation procedures. The components of the proposed energy-based procedure are developed consistently and are presented in such a way that this procedure can be readily adopted by practitioners who are already familiar with existing liquefaction evaluation procedures. The broader impacts of this work will help to minimize losses from earthquakes by improving the way engineers evaluate liquefaction.

Full textThis thesis takes advantage of the remarkable volatility of energy prices across both time and space over the past two decades to identify the impacts of increased fossil fuel energy prices on economic agents. It first examines one of the main sources of this renewed energy price volatility, the U.S. shale gas revolution, before turning to the analysis of two policy issues related to the implementation of carbon pricing: the risk of industrial investment relocation as a consequence of degraded competitiveness, and the distributional impacts of increased gasoline prices for households. The first chapter performs a detailed statistical analysis of an original dataset of 40,000 U.S. shale gas wells to calibrate a techno-economic model of shale gas extraction profitability, and finds that the shale gas revolution is not transferrable to continental Europe. The second chapter combines a database of 70,000 industrial M&A transactions covering 20 years and 41 countries with a sectoral industrial energy price index to identify the impact of relative energy prices on industrial investment location. Findings imply that firms tend to engage in more cross-border investments when their domestic energy prices increase in relative terms against foreign prices, which broadly supports the pollution haven hypothesis. Counterfactual policy simulations show that this effect is limited though. The third chapter develops a simple dynamic model of household gasoline consumption, using the rational habits framework to capture the intertemporal dimension of gasoline demand. This model is then estimated on PSID household-level data between 1999 and 2015 using localized gasoline prices. Estimation results show that households exhibit habits formation and forward-looking behavior in their gasoline consumption, and find a -0.88 long term price elasticity. Micro-simulations also find suggestive evidence of interactions between dynamic heterogeneity and the regressivity of gasoline price increases. The findings of this thesis strengthen the case for compensatory policies aimed at improving carbon pricing acceptance by economic agents, and provide tools that can contribute to their design and calibration

Wireless sensing technology has advanced greatly, but a critical obstacle to miniaturization and true autonomy is how to power sensors. Lithium ion batteries have been ideal power sources due to their high power density, but autonomy requires some form of power generation. The unique demands of miniaturization require power generation that can be isothermal and have a small cross-section. Lithium ion batteries can be used to generate power for wireless sensors in isothermal conditions. A novel circuit is proposed that can function in either a dual or single-temperature configuration. Novel cells are also proposed to maximize the effect of the system. LiCo02 used as a positive electrode with LiV2Os as a negative electrode (LCO/LVO) could theoretically generate 0.9mvK-1 in the dual-temperature system. Additionally, LCO/LVO cells used in conjunction with LiNio.Mno.1Co0.1O2 used as a positive electrode and LiFePO 4 used as a negative electrode should be able to generate 0.9mVK-1 when used in the single-temperature system.
