The present thesis, concerns the design procedure, modeling and implementation of the optimal configuration of the electric part of an experimental power plant, as well as the study of alternative generating unit configurations in the case of power generation from sea waves. An experimental power plant for power generation from sea waves was constructed on Psitalia in the frame of the research project PAVET 00BE142 entitled “Experimental Plant for Power Generation from Sea Waves”. The entire plant consisted of three similar units, each one involving a coupled hydraulic - mechanical - electrical system for wave energy extraction. Moreover, the case of linear synchronous generator with permanent magnets (LPMSG), as alternative unit for electric power generation from sea waves, has been studied. A particular, linear generator with permanent magnets was designed, accounting the features of the sea wave and the behaviour of the floating buoy. Appropriate coupled electromagnetic-mechanical-hydraulic models incorporating Finite Element Analysis (FEA) have been developed, enabling a dynamic simulation of the whole system performance involving a detailed field analysis of the permanent magnet linear generator. Also, a new hybrid simulation model, incorporating finite elements (FE) combined with analytical solution (macroelement) in the air gap area accounting for skewed magnets in linear generators (LPMSG) have been developed. The results of simulation of performance combined with the experimental measurements, illustrate the suitability of the developed models in applications for power generation from sea waves.

Στα πλαίσια της παρούσας εργασίας διερευνήθηκαν οι πιθανές εναλλακτικές διαμορφώσεις συζευγμένων ηλεκτρομηχανικών συστημάτων, κατάλληλων για την παραγωγή ηλεκτρικής ενέργειας από τον θαλάσσιο κυμάτισμά. Επίσης αναπτύχθηκαν κατάλληλα αριθμητικά μοντέλα για την προσομοίωση της λειτουργίας των απαιτούμενων συζευγμένων υποσυστημάτων (υδραυλικού - μηχανικού - ηλεκτρικού), για την σύνθεση μιας μονάδας ηλεκτροπαραγωγής με εκμετάλλευση την ενέργειας του θαλάσσιου κυματισμού. Τα μοντέλα εφαρμόστηκαν σε επιδεικτικό πειραματικό σταθμό μετατροπής της ενέργειας των θαλάσσιών κυμάτων σε ηλεκτρική, που κατασκευάστηκε στην Ψυτάλλεια στα πλαίσια του ερευνητικού έργου ΠΑΒΕΤ 00ΒΕ142, με τίτλο «Πειραματικός σταθμός παραγωγής ηλεκτρικής ενέργειας από θαλάσσιο κυμάτισμά». Ως εναλλακτικοί τύποι γεννητριών που μπορούν να χρησιμοποιηθούν για την ηλεκτροπαραγωγή από θαλάσσιο κυμάτισμά, εξετάστηκαν η γεννήτρια συνεχούς ρεύματος ξένης διέγερσης και η γραμμική γεννήτρια μονίμων μαγνητών. Τα δύο είδη γεννητριών, απαιτούν πλήρη ανάλυση της κατανομής του μαγνητικού τους πεδίου, καθώς ο εφαρμοζόμενος έλεγχος με στόχο την βελτιστοποίηση της παραγόμενης ενέργειας ακόμη και από κυμάτισμά χαμηλού ενεργειακού περιεχομένου, μπορεί να οδηγήσει σε βραχυχρόνια εμφάνιση φαινομένων τοπικού κορεσμού στο μαγνητικό υλικό των γεννητριών. Για την ανάλυση της κατανομής του μαγνητικού πεδίου γραμμικών γεννητριών μονίμων μαγνητών, αναπτύχθηκε μια νέα μεικτή τεχνική…

▼ Increasing the power density of the DC-DC converters requires the size and weight of the magnetic components, such as inductors and transformers, to be reduced. In this thesis, the losses in nanocrystalline inductor cores are characterised and analysed, including the traditional core loss and the gap loss caused by the air gap fringing flux. The loss calculations will form a basis for the design and optimisation of high power inductors for DC-DC converters for EV applications. This thesis first characterises experimentally the core losses in four nanocrystalline cores over a range of operating conditions that are representative of those encontered in typical high power converter applications, including non-sinusoidal waveforms and DC bias conditions. The core losses are assessed by the measured B-H loops and are characterised as a function of DC flux density, showing that for a fixed AC induction level, the losses can vary by almost an order of magnitude as the DC bias increases and the duty ratio moves away from 0.5. The results provide a more complete picture of the core loss variations with both DC and AC magnetisations than is available in manufactures’ data sheets. An electromagnetic finite element (FE) model is used to examine the gap loss that occurs in finely laminated nanocrystalline cores under high frequency operation. The loss is significant in the design example, contributing to almost half of the total inductor loss, and the gap loss is highly concentrated in the region of the air gap. The dependence of the gap loss on key inductor design parameters and operating condtions is also explored. An empirical equation is derived to provide a design-oriented basis for estimating gap losses. Thermal finite element analysis is used to estimate the temperature rise and identify the hot spot in a nanocrystalline inductor encapsulated in an alumimium case. The temperature distribution in the core largely corresponds to the non-uniform distribution of the gap loss. The thermal FEA can also be used to evaluate different thermal management methods to optimise the design for a more compact component. The FE modelling of gap loss and the thermal predictions are validated experimentally on a foil-wound Finemet inductor, showing good agreement between the predictions and measurements under various operating conditions.

▼ Commando Country assesses the nature of more than 30 special training centres that operated in the Scottish highlands between 1940 and 1945, in order to explore the origins, evolution and culture of British special service training during the Second World War. These locations were chosen by virtue of the utility of the physical environment of the highland estate, strongly influenced by associated ideas about the challenge of that environment, individual character and the nature of irregular warfare. By virtue of its Scottish geographical perspective, Commando Country diverges from the existing literature by looking across the training establishments used by different organisations, principally Military Intelligence, the Commandos, and Special Operations Executive (SOE), whose histories tend to be considered in isolation. The book investigates the development and function of each category of training centre, the relationships between them, and their place in the broader framework of British and Allied special operations. Based on research in official documentary sources, unpublished and published memoirs and on fieldwork and interviews with surviving participants conducted by the author, Commando Country also presents rare unpublished photographs from public and private sources and artefacts assembled for the exhibition of the same name held at the National War Museum, Edinburgh in 2007. The resulting thesis is that the philosophy and practice improvised at the original school of irregular warfare at Inverailort House in the summer of 1940 permeated the culture of the training centres that developed thereafter. Close attention is accordingly given to the circumstances, organisation and instructing personnel that created the Inverailort syllabus, and the backgrounds and skills brought to bear, some drawn from civilian professions. The application of similar methods to the newly formed Commando forces is then traced. In this context the original operational purposes of individual aspects of the training became standardised into a general test of fitness and character designed to control admission of volunteers into the Commandos, the raiding and assault units that regarded themselves as a new military elite. Simultaneously, the approach pioneered at Inverailort was adapted to form the paramilitary training element of SOE, the organisation that coordinated and supported Resistance organisations in enemy-occupied countries. Particular attention is paid to the dedicated training establishments for Polish and Norwegian SOE units based in Scotland. The book concludes by considering how techniques and philosophy were applied more widely as conventional military training itself evolved, extending influence even into postwar civilian outdoor recreation.

Research Doctorate - Doctor of Philosophy (PhD)

Condition monitoring of induction motors is of much importance for their efficient and reliable operation. Most of the existing electrical techniques of condition monitoring and fault diagnosis are based on current, voltage, vibration and flux measurements external to the motor. Among these, most of them are based on motor stator current analysis. The most popular and well researched group of techniques are based on the motor current signature analysis (MCSA), which reveals motor condition through the changes of the stator current frequency spectrum. Although very powerful, MCSA has its shortcomings, including the need for long sampling times in steady state to achieve acceptable spectral resolution, dependence of successful diagnosis of some faults on the accurate knowledge of the motor slip, and potential ambiguity of interpretations. Besides, the characteristics of external signals such as current, leakage flux etc. are produced in the air gap flux density, which is a function of time and space. It is very information-rich, and contains ample indications of any imbalance or fault once it occurs. When transformed into a signal available for external measurements, this information is greatly reduced and distorted, as well as it loses space dimension. This thesis attempts to address the condition monitoring challenges by removing the limitations of a typical external sensor instrumentation. It is proposed to instrument a motor with an array of miniature Hall Effect Flux Sensors (HEFS) to measure the air gap flux density at multiple points around the air gap circumference. Internal instrumentation with an array of flux sensors is chosen in this thesis, because it allows to directly measure the air gap flux as a function of time and space, thereby conserving the space domain information to the benefit of condition monitoring. It also does not interfere with the motor operation and unlike search coils (which measure flux derivative), HEFS measures flux and their signal is less susceptible to noise distortions, which is particularly important for inverter driven motors. One important point to note is the additional cost due to sensor instrumentation. However, for production-critical large motors used in industries such as mining, petrochemical etc. are produced in fewer numbers, which are expensive to replace in case of a fault or failure. Also, the down time cost of these motors in terms of production loss is much higher than the extra instrumentation cost. Besides, instrumentation cost can be reduced if it is integrated in the manufacturing process of the motor. Additional functionality of the proposed instrumentation is described in the thesis. The resulting certainty about each motor condition at any point in time significantly reduces the risk of unplanned downtime and offsets the instrumentation cost by a large margin. Fundamental theory behind the air gap flux density as a function of time and space, and its distortions introduced by various faults, is analyzed in…

▼ Historically, there are persistent diploma gaps permeating between general education students and students with disabilities. In comparison to their peers, there are fewer youth with disabilities graduating from high school with regular diplomas. Regular diploma attainment is of critical importance because this credential is viable to postsecondary outcomes such as higher education and meaningful employment. An analysis of graduation outcomes in Virginia from 2010-2013 revealed that 19 of 132 school divisions met or exceeded statewide performance expectations for youth with disabilities. In alignment with the Elementary and Secondary Education Act of 2010, the Virginia Department of Education monitors and reports Indicator 1: Percent of youth with Individualized Education Programs graduating from high school with a regular diploma using the adjusted four-year cohort graduation rate. Indicator 1 is among four secondary education and transition data indicators that are federally monitored, collected, and analyzed to determine progress or lack of progress. The purpose of this study was to identify the policies and practices that special education directors perceived as contributing to meeting the state graduation performance measures for youth with disabilities in 10 Virginia school divisions during the 2010-2013 school terms. A three-round Delphi method was employed to seek consensus from a panel of Special Education Directors whose divisions are consistently meeting Indicator 1 performance measures. Investigated were their perceptions of best practices and strategies that are paramount in graduating students with disabilities with a regular diploma or higher. Panelists identified 70% or greater agreement on the importance of six (60%) strategies contributing to regular diploma attainment for this population of students. These statements of practice were determined to be of considerable importance (rated as critically effective or somewhat effective), and in rank order were: 1) providing targeted interventions such as remediation, tutoring, and credit recovery options; 2) conveying high expectations; 3) tracking and monitoring; 4) IEP development with emphasis on Transition, student family participation, exploring continuum options, accommodations and modifications, assessment, and diploma status; 5) promoting learning, attendance, and a positive school environment; and 6) policies that support all students. Further, a theme emerged as it relates to implementation on four of the six statements of practice on which consensus was reached in the final Delphi round. The data provided evidence that student engagement, parental involvement, and building positive relationships with an adult are important factors in support of the identified strategies toward graduating these youth with a regular/standard diploma. Implications for practice were recommended for school and division leaders, and state policymakers. Advisors/Committee Members: Cash, Carol S. (committeechair), Rose, Valija C.

▼ This thesis presents investigations on air-cooled air gap membrane distillation for desalination and the application of radial waveguides based on total internal reflection for solar thermal desalination. Using an air-cooled design for an air gap membrane distillation (AGMD) process may result in significantly lower energy requirements for desalination. Experiments were conducted on AGMD module to study the effect of air gap, support mesh conductivity and hydrophobicity, condensing surface hydrophobicity. A novel modular design was used in which modules could be used in a series configuration to increase the flux value for the distillate. The output from the series configuration was found to have about three times the production from a single pass water-cooled system with the same temperature difference between the saline and clear water streams. The results also indicated that the mesh conductivity had a favorable effect on the flux value whereas the hydrophobicity of the mesh had no significant effect. The hydrophobicity of the condensing surface was favorable on two accounts: first, it led to an increase in the flux of the distillate at temperatures below 60 °C and second, the temperature difference of the saline feed when it enters and leaves the module is lower which can lead to energy savings and higher yields when used in a series configuration. The second part of the thesis considers use of low-cost radial waveguides to collect and concentrate solar energy for use in thermal desalination processes. The optical-waveguide-based solar energy concentrators are based on total internal reflection and minimize/eliminate moving parts, tracking structures and cost. The use of optical waveguides for thermal desalination is explored using an analytical closed-form solution for the coupled optical and thermal transport of solar irradiation through a radial planar waveguide concentrator integrated with a central receiver. The analytical model is verified against and supported by computational optical ray tracing simulations. The effects of various design and operating parameters are systematically investigated on the system performance, which is quantified in terms of net thermal power delivered, aperture area required and collection efficiency. Design constraints like thermal stress, maximum continuous operation temperature and structural constraints have been considered to identify realistic waveguide configurations which are suitable for real world applications. The study provides realistic estimates for the performance achievable with radial planar waveguide concentrator-receiver configuration. In addition to this, a cost analysis has been conducted to determine the preferred design configurations that minimize the cost per unit area of the planar waveguide concentrator coupled to the receiver. Considering applications to thermal desalination which is a low temperature application, optimal design configuration of waveguide concentrator-receiver system is identified that result in the minimum levelized cost of power… Advisors/Committee Members: Pitchumani, Ranga (committeechair), Mahajan, Roop L.

As características de desempenho dos motores trifásicos de indução são fundamentais para estudos de viabilidade econômica, tanto para a manutenção como para a substituição por motores que apresentem melhor rendimento, visando à economia de energia. Existem diversos procedimentos para determinar o desempenho das máquinas de indução, no entanto, são procedimentos baseados em ensaios que exigem o desacoplamento mecânico, comprometendo assim a praticidade, sem contar no custo da instrumentação envolvida. Este trabalho apresenta o estudo e implementação de dois métodos distintos para estimar o rendimento de forma pouco intrusiva, método do torque no entreferro e método do circuito equivalente. Nesse último são estudadas duas técnicas, a primeira estima os parâmetros do circuito equivalente por meio de um conjunto de equações definidas pela resolução do modelo da máquina, e a segunda, estima os parâmetros do circuito equivalente por meio de um algoritmo de identificação por mínimos quadrados. Por fim são mostrados os resultados da aplicação das metodologias propostas no Laboratório de Eficiência Energética e Hidráulica em Saneamento – LENHS da Universidade Federal do Rio Grande do Sul, onde então é apresentada uma análise dessas técnicas, considerando os aspectos de precisão e incerteza.

The performance characteristics of three-phase motors are essential for economic feasibility studies, for both maintenance and for replacement by motors that have better efficiency, to save energy. There are several procedures based on tests that require mechanical uncoupling, thereby committing practicality, without counting the cost of the instrumentation involved. This work presents the study and implementation of two different methods to estimate the efficiency in low intrusive order, method of air gap torque and method of equivalent circuit. In the latter, two techniques are studied, the first estimates the equivalent circuit parameters though a set of equations defined by the resolution of the machine model, and second, estimates the equivalent circuit parameters by means of an identification algorithm for least squares. Finally shows the results of applying the proposed methodologies in the Laboratory of Energy Efficiency and Water Sanitation – LENHS in Federal University of Rio Grande do Sul, where it is then presented an analysis of these techniques, considering aspects of precision an uncertainty.

Sukamas javų kombaino kūlimo būgnas sukuria oro srautą tarpe tarp būgno ir pobūgnio. Dalis oro nukreipiama pro pobūgnio ardelius. Darbe atlikti oro srauto greičio tarpe tarp kūlimo būgno ir pobūgnio bei pobūgnio ardeliuose tyrimai. Laboratoriniai tyrimai atlikti stacionariu tangentiniu vienbūgniu kūlimo stendu, kurį sudarė 0,6 m skersmens ir 1,2 m pločio aštuonių spragilų tangentinis kūlimo būgnas, kurį 146º kampu gaubė ardelinis pobūgnis. Pateiktos oro srauto greičio tarpe tarp būgno ir pobūgnio bei pobūgnio ardeliuose priklausomybės nuo technologinių ir konstrukcinių kūlimo būgno parametrų. Laboratoriniais tyrimais nustatyta, jog kūlimo būgno konstrukciniai ir technologiniai parametrai sąlygoja būgno sukuriamą oro srautą. Oro srauto greitis didėja pobūgnio galo link. Būgną sukant 350 min-1 dažniu (spragilų linijinis greitis vs=11 m s-1), greičių skirtumas pirmojoje ir trečiojoje pobūgnio dalyse siekia 1 m s-1, o padidinus sukimosi dažnį iki 750 min-1 – apie 3 m s-1. Didinant kūlimo būgno sukimosi dažnį nuo 350 min-1 iki 750 min-1 oro srauto judėjimo greitis tarpe tarp būgno ir pobūgnio bei pobūgnio ardeliuose didėja, tačiau spragilų greičio nepasiekia. Būgno tarpspragiliuose pritvirtinus 8 balastus, oro srauto greitis tarpe tarp būgno ir pobūgnio sumažėjo 10%, o tarpspragilius uždengus dangalais – 37% lyginant su įprastos tarpspragilių konstrukcijos būgnu. Pobūgnio ardeliuose oro srauto greitis atitinkamai sumažėjo 9% ir 33%. Tolimesniais eksperimentiniais tyrimais... [toliau žr. visą tekstą]

The rotation of combine harvester threshing cylinder creates an air flow within threshing crescent, part of which is directed through the openings in the concave. The present work gives the air flow velocity trials within threshing crescent. Experimental studies were carried out with a stationary tangential threshing cylinder stand which consisted of 0.6 m diameter and 1.2 m wide eight rasp bars tangential threshing cylinder which is surrounded by concave with 146º. Air velocity was measured at 56 locations, distributed dependent on construction of concave. The air velocity was measured using a hot wire anemometer unit. The output data was recorded on PC using 10 bit ADC converter. Nine levels of cylinder peripheral speed (from 11.0 ms-1 to 23.6 ms-1) at cylinder-concave clearances of: 36 mm at front, 32 mm in middle, and 20 mm at rear part of concave were used in this experiment. The results of the experiment show that there were significant differences of air velocity among cylinder peripheral speeds and locations. The air velocity increased with increased cylinder peripheral speed and towards the rear of the concave. Air flow velocity within threshing crescent dependence on technological and constructional parameters of the threshing cylinder is presented. Threshing cylinder with mounted 8 ballast and cylinder with covered space between rasp bars creates an air flow, whom velocity was respectively 10% and 37% lower compared with the standard cylinder construction.

Water stress is an ongoing problem in many places in the world, while the demand for clean and safe freshwater is growing due to the increasing population. In many developing countries, water supplies often are contaminated with arsenic, fluoride, etc. Therefore, it is important to realize that water scarcity and contamination issues concern only one sector but many. HVR Water Purification AB is developing a water purification prototype – ELIXIR 500 - using the air gap membrane technology and is implemented in Odisha, India, aiming to supply with 200 litre water daily. This thesis aims to estimate future energy sources to supply this prototype and explore the possibilities of using only renewable energy resources from technical, economic, and environmental perspectives. These are achieved by firstly identifying the energy possibilities in Odisha, India, and then calculating the feasibility of each solution chosen and finally analyzing the results. Among the energy sources, which are power grid, wind and solar power, diesel generator and solar-diesel hybrid system. It is found that the energy source to the prototype supplied by the power grid is 0.057 USD per litre water, which is the cheapest option. However, it is not feasible due to the lack of electrification from the local network. Meanwhile, the solar-diesel hybridized energy system is the most economical option if renewable energy sources are integrated with 0.11 USD per litre water.

Det är därför viktigt att inse att vattenbrist och föroreningar inte bara rör en sektor utan många. HVR Water Purification AB utvecklade en prototyp för vattenrening - ELIXIR 500 - med hjälp av luftspaltmembrantekniken (eng: air gap membrane distillation och implementeras redan i Odisha, Indien, med målet att förse 200 liter rent vatten dagligt.

▼ As the United States (U.S.) population continues to change and become racially/ethnically, culturally, linguistically, and economically diverse, so does the population in public schools (Institute of Education Sciences, 2010). Additionally, the number of culturally and linguistically diverse (CLD) students has been overrepresented in the subgroup of students with learning disabilities (SLD) (Artiles & Ortiz, 2002; Kalynpur & Harry, 2012; Klingner & Harry, 2014). Therefore, there is a need to adapt the curriculum and pedagogy to teach the growing number of diverse students in public schools. The results of national assessments show that students of color have lagged behind their White counterparts in mathematics achievement over the years (Cortes, Goodman, & Nomi, 2013). Despite the push to remediate this problem, teachers continue to use ineffective teacher-led practices and the achievement gap persists across public schools (Williams, 2011). The use of cultural responsive teaching (CRT) among CLD students is promising (Santamaria, 2009). However, there is need to investigate the use of these practices in Algebra I courses with CLD students with SLD. The present 17-week pre-post study compared student achievement in Algebra I courses between two groups of CLD students with SLD (N=63). These groups were (a) 31 students who received CRT (treatment group) by teachers who received CRT training and (b) 32 students who received instruction by teachers who did not receive CRT training (control group). There are significant differences between the treatment and the control group on the CLD students with SLD Algebra I Mid-Year Assessment (MYA) and the students’ Mathematics Self-Efficacy scores (MSES). The teachers’ level of cultural consciousness had an insignificant covariance on the Algebra I MYA, yet the teachers’ observations and their cultural responsive self-assessment had a direct effect on the Algebra I MYA. Additionally, there was not significant interaction between MSES and TCS on the students’ Algebra I MYA. The results of the study suggest that the use of CRT is a promising practice to improve CLD students’ with SLD Algebra I achievement and perhaps close the math achievement gap.

▼ Large disparities exist in the dropout and incarceration rates of different races, genders, and disabilities. These two phenomena, commonly referred to as the Achievement Gap and Incarceration Gap, also contribute to other problems within society and cost taxpayers billions of dollars annually. Because of the intersection of race, gender, and disability, African-American males in special education have both the highest dropout and incarceration rates. However, few studies have focused on this specific subgroup and the factors contributing to their significantly lower outcomes. The purpose of this study is to examine the differences between successful and unsuccessful African-American males in special education at a Los Angeles High School. Specifically, it will compare high-achieving and non-delinquent African-American males in special education to their low-achieving and delinquent counterparts. This comparison will be done across various environmental and personal (psychological) factors in an effort to explain what contributes to the high dropout and incarceration rates among the population. A total of fifteen environmental factors across the home, community, and school environments were explored. The psychological constructs of self-efficacy and school engagement were explored as personal factors. Data were collected utilizing a mixed-method approach with quantitative surveys and qualitative focus groups. Quantitatively, chi-square tests were used to compare frequencies across environmental factors while t-tests were used to compare student means across personal factors. Qualitative data was organized into themes and reported with its corresponding research questions. A total of 31 students completed surveys and 16 students participated in focus groups. All participants were between the ages of 14 through 19. Findings indicate significant differences across both the environment and personal factors of successful and unsuccessful African-American males in special education exist. Findings also indicate more significant differences exist between non-delinquent and delinquent students than high and low achieving students. Based on these findings, several changes may be implemented to reduce dropout and incarceration rates among this most vulnerable group.

Increasing the power density of the DC-DC converters requires the size and weight of the magnetic components, such as inductors and transformers, to be reduced. In this thesis, the losses in nanocrystalline inductor cores are characterised and analysed, including the traditional core loss and the gap loss caused by the air gap fringing flux. The loss calculations will form a basis for the design and optimisation of high power inductors for DC-DC converters for EV applications. This thesis first characterises experimentally the core losses in four nanocrystalline cores over a range of operating conditions that are representative of those encontered in typical high power converter applications, including non-sinusoidal waveforms and DC bias conditions. The core losses are assessed by the measured B-H loops and are characterised as a function of DC flux density, showing that for a fixed AC induction level, the losses can vary by almost an order of magnitude as the DC bias increases and the duty ratio moves away from 0.5. The results provide a more complete picture of the core loss variations with both DC and AC magnetisations than is available in manufactures’ data sheets. An electromagnetic finite element (FE) model is used to examine the gap loss that occurs in finely laminated nanocrystalline cores under high frequency operation. The loss is significant in the design example, contributing to almost half of the total inductor loss, and the gap loss is highly concentrated in the region of the air gap. The dependence of the gap loss on key inductor design parameters and operating condtions is also explored. An empirical equation is derived to provide a design-oriented basis for estimating gap losses.Thermal finite element analysis is used to estimate the temperature rise and identify the hot spot in a nanocrystalline inductor encapsulated in an alumimium case. The temperature distribution in the core largely corresponds to the non-uniform distribution of the gap loss. The thermal FEA can also be used to evaluate different thermal management methods to optimise the design for a more compact component.The FE modelling of gap loss and the thermal predictions are validated experimentally on a foil-wound Finemet inductor, showing good agreement between the predictions and measurements under various operating conditions.

Uma das condições mais comuns responsável pela perda auditiva durante a infância é a Otite Média (OM). A OM ainda é considerada “questão de saúde pública” devido à sua alta prevalência e distribuição mundial. Há poucos estudos na literatura que relatam as alterações na orelha contralateral (OCL) em pacientes com otite média crônica (OMC). Para enfatizar esses conceitos e analisar com mais profundidade a prevalência de bilateralidade na OMC, há vários anos iniciamos uma linha de pesquisa, focalizando três cenários diferentes: a histopatologia (ROSITO, COSTA, SCHARCHEN, 2007); o padrão clínico e otoscópico (COSTA et al., 2008) e a fisiologia (função auditiva) no presente estudo. Objetivo: Avaliar a função auditiva da OCL em pacientes com OMC através do gap aéreo-ósseo. Comparar os dados audiométricos da OCL levando em conta se o paciente apresenta Otite Média Crônica não Colesteatomatosa (OMCNC) ou Otite Média Crônica Colesteatomatosa (OMCC) na orelha principal (OP). Métodos: Estudo transversal, comparativo e contemporâneo, com 1000 pacientes com diagnóstico de OMC submetidos a exame otorrinolaringológico, videotoscopia e audiometria tonal liminar (ATL). Resultados: A prevalência de gap aéreo-ósseo foi de aproximadamente 40%, tanto na amostra total e na análise estratifica por tipo de OM (na amostra geral houve 392 (39,2%) pacientes, no grupo com OMCNC houve 279 (40,8%), e no grupo com OMCC foram 113 (37,17%). Conclusões: Assim como os achados de estudos clínicos e histopatológicos, a prevalência de alterações audiológicas na OCL foi elevada, evidenciando o caráter bilateral na OMC.

Otitis media (OM) is one of the leading causes of hearing loss in childhood. Due to its high prevalence and worldwide distribution, OM is still regarded as a public health issue. Nevertheless, few studies have assessed involvement of the contralateral ear (CLE) in patients with chronic otitis media (COM). To demonstrate the bilateral nature of COM, we designed three distinct studies, which focused on histopathology and anatomy, clinical findings and physiology (both previously published), and, finally, auditory function. Objective: To measure auditory function in the CLE in a sample of COM patients by means of air-conduction thresholds, bone-conduction thresholds, and the air-bone gap, and to compare CLE audiometry findings in patients with non-cholesteatomatous (NC-COM) or cholesteatomatous chronic otitis media (CCOM). Methods: This was a cross-sectional, contemporary and comparative study of 1000 patients with a diagnosis of COM. Clinical ear examination, video otoscopy, and pure-tone audiometry (PTA) were performed. Results: The overall prevalence rate of air-bone gap was approximately 40%, both in the total sample and after stratification by type of OM (393 [39.2%] patients overall, 279 [40.3%] in the NC-COM group, 113 [37.17%] in the CCOM group). Conclusions: As did clinical and histopathology findings in previous studies, audiological evaluation revealed a substantial prevalence of CLE involvement, providing evidence of the…

▼ Plastic materials form an important constituent of connectors and PCB substrates which are indispensable for connector and printed circuit industries. Plastics such as FR-4, PTFE (Teflon), PVC and silica glass are some of the commonly used materials for connector and printed circuit fabrication. With high-speed electronics being the increasing trend, computers, electronic chips and other electronic devices are progressively moving to higher frequencies with CPU speeds approaching 5 GHz and more in the future. Many systems are operating in 1-10 GHz range, and in the future, applications running at frequencies as high as 20 GHz with high data rates will be feasible. Knowledge of the performance of the materials constituting these devices is an imperative and challenging research task for designers. Dielectric characterization of plastic materials commonly used in electronic devices over a wide frequency range determines the electrical performance of the plastics and in turn of the electronic devices at high frequencies. In this thesis, wideband dielectric characterization of Triethylene Glycol Dimethacrylate Ester (TrEGDMA) organic plastic material (named Visi Jet SR-200 commercially) is performed using coaxial airline technique in the frequency range of 1-18 GHz and free space measurement technique in the frequency range of 8-12 GHz. This organic plastic has not been characterized over such a wide frequency range, therefore, dielectric characterization of this plastic is the main contribution of the research. The coaxial airline technique has been used to perform accurate measurements of dielectric properties of the plastic over frequency range of 1-18 GHz. A simulation analysis is also performed using known material (Teflon) as well as unknown plastic material to be characterized (TrEGDMA) to determine reflection and transmission coefficients and compare them with the measured results. Dielectric models for the measured permittivity data have been proposed to analytically describe the frequency dependency of dielectric properties of the TrEGDMA plastic over 1-18 GHz frequency range which is another important contribution of the research. Extraction of permittivity from measured scattering parameters using analytical closed form expressions has also been described. The dielectric characterization of the TrEGDMA plastic material will contribute towards determining the signal integrity performance of interconnects with this plastic as a substrate and will help to determine whether or not the material is fit to be used as a substrate in interconnects for high speed data transmission.

▼ The thin solidifying shell in the meniscus region of a continuous caster deforms due to severe contraction in steels of near-peritectic composition, thereby exacerbating the risks of cracking and in the extreme, breakouts. The main purpose of the present study was to contribute to an improved understanding of the fundamentals underpinning the solidification behaviour of selected steels of industrial importance and to relate these fundamentals to industrial practice. A further aim was to explore the potential of countermeasures aimed at avoiding or at least minimizing surface defects that originate as a result of the occurrence of the peritectic phase transition. Several experimental techniques were employed to simulate various aspects of solidification events that occur in the meniscus region of an operating continuous caster. In-situ observations of solidification in addition to subsequent solid-state phase transformations were made by employing a concentric solidification technique in a high-temperature laser-scanning confocal microscope (HTLSCM) in real time and at temperature. It is possible by this technique to effectively simulate early solidification events occurring in an operating continuous caster and the solidification behaviour of a series of steel of near-peritectic composition and of industrial importance have been assessed and compared. Differential scanning calorimetry (DSC) was employed to determine the exact phase relationships in the selected steels as a function of temperature as an aid to the interpretation of the outcomes of the solidification studies. A potential countermeasure that can be taken in industrial practice to counteract uneven solidification is to texture the mould surface. In order to explore and evaluate the effect of different mould surface textures on reducing the unevenness of the solidifying, a simple dip-test was developed, followed by more sophisticated experiments and analyses in a continuous casting mould simulator. In parallel to the texture studies in the mould-simulator certain aspects of the interaction between mould, strand and mould-flux have also been assessed. The stresses encountered in and development of these stresses in the course of solidification, were assessed by the use of a submerged split-chill contraction (SSCC) technique. In an attempt to relate the fundamental studies to operational practice, an in-plant study of off-corner crack formation was conducted. The solidification studies conducted in a high-temperature laser-scanning microscope revealed that the velocity…

Lors d’une démarche de modélisation énergétique d’un bâtiment, la prise en compte de l’enveloppe solaire reste souvent imprécise. L’objet du travail présenté ici est la description détaillée de solutions de protections solaires, induisant un tirage thermique (bardage, store), dans un objectif de modélisation et de valorisation pour répondre aux besoins d’industriels du secteur ; la caractérisation des performances permet alors d’assister la maitrise d’œuvre en phase conception.La mise en place d’une plateforme expérimentale – mur exposé sud muni d’une protection solaire devant lame d’air – a permis la mesure de températures d’airs et d’éléments solides présents dans le système, de vitesses d’écoulement dans la lame d’air ouverte, et du flux radiatif incident. Deux types de bardage bois, un type de store et un type de métal déployé ont été considérés.Parallèlement, un modèle 1D amélioré de transfert de chaleur dans le système étudié est développé. Trois familles de modèle de convection dans la lame d’air sont identifiées, présentées et intégrées dans le modèle global. La description de l’écoulement dans la lame d’air est retenue à partir d’analyses des résultats expérimentaux.Un modèle simplifié d’intégration de tels systèmes de protections solaires dans des plateformes de simulation thermique de bâtiments est proposé, basé sur la paramétrisation des sollicitations extérieures par le facteur solaire. La méthode de calcul du facteur solaire est présentée. Le caractère intrinsèque facteur solaire et son intérêt sont discutés notamment à partir d’analyse de sensibilités.

During the design process of a building, the energetic modelling of the solar envelop is often imprecise. The purpose of the present work is the detailed description of solar shading devices that induce a chimney effect such as claddings or blinds, which would allow their promotion in order to meet the industrial needs of the sector. An experimental platform – south facing wall with a shading solar device that define an air gap – has been set up and allow the measurement of temperatures, air flows in the ventilated air gap, and the incident solar radiation. Two different wooden claddings, one type of blinds and one type of expanded metal were considered.A 1D model has been developed by considering precisely the heat transfers in the system. Three families of convection model are identified, presented and integrated in the overall model. The description of the airflow in the air gap is chosen from analysis of the experimental results.A simplified model that allows the integration of such solar shading devices in a building simulation platform has been developed; it is based on the parameterization of external solicitations as function of the shading device properties. The calculation method of the solar factor is presented. The intrinsic nature of the solar factor is then discussed using sensibility analysis.

▼ Air insulation, especially its efficiency, is often underestimated and most often it is recommended as combination of several methods by our experts. It is known that flowing air used to eliminate excessive humidity in lower construction is insignificantly promoted. Already our ancestors in ancient Rome had experience with implementation of air insulations. However, nowadays such design is connected with many doubts and it forces us to use sense, especially knowledge of construction physics. So it urges higher technical precision when designing functional ventilation system. Each building is actually a unique object, with regard to its position and used properties, that is why certain natural conditions must be accepted when designing. It is more complicated and figuratively speaking it can be written in c. 20 equations of twenty unknowns. Other problems arise in unknown coefficients to individual parameters and their effects. From another point of view it is the issue of changing air during the day, passing fronts, annual cycles and all of these in relation to internal environment of the building, materials used in the construction, land properties of rocks, and last but not least, relation to the terrain around the building. Then there are the effects of the building's altitudes etc. In total they are cycles with sine character of dampening and drying. The thesis discusses how to test the functionality of AIR insulations designed for the floor ventilation in historic buildings and follows on from the previously published articles. A flow analysis is being performed on an object of the city of Žirovnice which has been registered in the list of cultural monuments and was built as a brewery in the years 1589-1592 on the site of an older medieval building. This article brings new air-flow element. The aim of the article is to analyse in detail the air flow in a specific floor void with the aid of modern CFD programs and experimental measurements using the ALMEMO Advisors/Committee Members: Škramlik, Jan (advisor), Kmínová,, Hana (referee), Šilarová,, Šárka (referee), Šťastník, Stanislav (referee).
