Abstract:
In light of increasing integration of renewable and distributed energy sources, power systems are undergoing significant changes. Due to the fast dynamics of such sources, the system is in many cases not quasi-static, and cannot be accurately described by time-varying phasors. In such systems the classic power flow equations do not apply, and alternative models should be used instead. In this light, this paper offers a tutorial on the dynamics and control of power systems with distributed and renewable energy sources, based mainly on the dq0 transformation. The paper opens by recalling basic concepts of dq0 quantities and dq0-based models. We then explain how to model and analyze passive networks, synchronous machines, three-phase inverters, and how to systematically construct dq0-based models of complex systems. We also highlight the idea that dq0 models may be viewed as a natural extension of time-varying phasor models, and discuss the correct use and validity of each approach.

Abstract:
This paper presents a non-iterative technique that generates reference current to manage operation of a three-phase four-wire shunt active power filter which employs a three-leg split capacitor voltage source inverter (VSI) topology. The proposed technique integrates together a self-tuning-filter (STF) and direct-quadrature-zero (dq0) principle (referred here as STF-dq0), allowing the controlled shunt active power filter (SAPF) to perform effectively under distorted source voltages and unbalanced load conditions. Unlike the previous technique developed based on the standard dq0 principle, the proposed technique does not require any service from a phase-locked loop (PLL) where two STFs are applied to separate harmonic and fundamental elements for the purpose of generating synchronization phases and reference current, respectively. Simulation work which includes connection of the SAPF circuits, design of control techniques and all the necessary assessments are conducted in MATLAB-Simulink platform. Performance achieved by the SAPF while utilizing the proposed technique is thoroughly investigated and benchmarked with that demonstrated by the SAPF while using the standard dq0 technique, to evaluate the inherent advantages. Exhaustive simulation results are provided and thoroughly discussed to support design concept, effectiveness, and benefits of the proposed technique.

Abstract:
This paper proposes a novel deadbeat torque and flux control (DB-DTFC) to reduce torque ripple for switched reluctance motor (SRM). DB-DTFC combines the advantages of direct torque control (DTC) and space-vector modulation (SVM). DB-DTFC leads current vector control into DTC in order to find the equation between torque and current through deadbeat prediction theory i.e. a beat reaches a given point. In addition, the deadbeat calculation module here is similar to that of permanent magnet synchronous motor. Based on dq0 reference frame of SRM, the most suitable dq0 axis current of next moment corresponding to different torque errors is calculated and predicted. According to the calculated dq0 axis current, the optimal space voltage vectors can be selected to reduce torque ripple. In order to verify the effectiveness and correctness of the proposed scheme, DB-DTFC is verified and compared with the DTC-SVM by simulation.

Abstract:
Abstract This paper presents distribution static compensator (DSTATCOM) with dq0 current controller and sine pulse width modulation (SPWM) switching for compensation of unbalanced nonlinear load in distribution system. DSTATCOM, connected in parallel to load at the point of common coupling (PCC), is used for supplying reactive and harmonic components of load current demand. This dq0 current controller is implemented in synchronous reference frame (SRF) rotating at fundamental frequency and consists of harmonic compensation (HC) regulator along with proportional integrator (PI) regulator. HC regulator is realized by number of sinusoidal signal integrators (SSIs) in parallel. The SSI provides high gain for tuned harmonic frequency and helps in minimizing filter current tracking error while compensating for load harmonic currents. Zero-axis controller, which compensates load neutral current and helps in obtaining balanced utility currents, is provided along with d, q controllers. SPWM switching generates inverter gating pulses at constant frequency, which reduces stress levels on VSI switches and simplifies the design of interface filter. Simulation studies of DSTATCOM load compensation with dq0 current controller are carried out in Matlab/Simulink and experimental verification is done using dSpace 1104 with Matlab real-time interface (RTI).

This paper presents a method based on adaptive two-dimensional wavelet packet for three-phase power quality data. In this paper, we shall briefly introduce the method of dq0 transformation. First, the original data is converted by the method of dq0 transformation, its purpose may be to eliminate redundancy between the three-phases alternating data, then change the one-dimensional date converted into a two-dimensional matrix by the integral multiple of cycles, which aims to eliminate redundant between cycles. Finally, use the method of two-dimensional adaptive wavelet packet decomposition, image SPIHT coding and DEFLATE coding to compress the data. The simulation result shows that the algorithm effectively compress the three-phase power quality data, and it has a good compression effect.

Abstract:
Introduction. Coeliac disease is a genetically determined disease associated with the HLA-DQ2 and DQ8 genes. According to European data, these alleles are detected in more than 95% of patients. The results of earlier studies in various regions of the Russian Federation and the constituent republics have shown a lower incidence of HLA-DQ2/DQ8 in children with coeliac disease (60–80%). These data served as a basis for discussion about regional genetic features and the potential for disease development in a significant proportion of patients without DQ2/DQ8 alleles.Methods. Genetic screening was conducted on 275 children with coeliac disease. According to the results of the study, the patients were assigned to genetic risk groups.Results. HLA-DQ2/DQ8-alleles were detected in 274 children (99.6%), with 86.9% of patients having DQ2 molecule in genotype and 12.7% having DQ8 molecule. Among 239 DQ2-positive patients, 33.5% were DQ2 homozygous. The remaining DQ2-positive patients had the following HLA-DR-DQ allele distribution: DR3-DQ2/DR5-DQ7 – 8.7%, DR7-DQ2/DR5-DQ7 – 13.4%, DR3-DQ2/ DRx-DQx – 22.2%, DR7-DQ2/DRx-DQx – 2.2%. In five children the incomplete DQ2 molecule was determined, represented by DQA1*0501 allele, while in four patients DQA1*501 was associated with DQB1*0301 allele forming DR5-DQ7 molecule. We found high and significant risk alleles in 29.1% and 22.2% of cases, while moderate and low risk alleles were found in 27.3% and 21.4% of cases respectively.Conclusions: In Russian children with coeliac disease the prevalence of HLA-DQ2/DQ8 alleles corresponds to European data. Low detection frequency of HLA-DQ2/DQ8 molecules in Russian coeliac patients, which was reported earlier, may be due to peculiarities of the approach to the disease diagnostics, which do not correspond to modern Russian and international recommendations.

Abstract:
Coeliac disease (CD) is a systemic autoimmune, complex and multifactorial disorder, which is caused by interactions between genetic and environmental factors. The only established genetic risk factors so far are the human leucocyte antigens. The aim of this study was to assess the distribution of II class human leukocyte antigens (HLA) in patients with coeliac disease and to investigate the susceptibility to coeliac disease in family members. We typed HLA DR and DQ antigens in 37 patients from Vojvodina with coeliac disease, 23 first-degree relatives, and 210 controls, serologically using standard lymphocytotoxicity technique. HLA DQ5(1), DQ6(1), DR11(5), DQ7(3), DQ2 and DR15(2) were the most common antigens in the control group. Frequency of HLA DQ2, DR3 and DR7 was higher in CD patients than in the control group. The relative risks for HLA DQ2, DR3 and DR7 were 4.846, 6.986 and 2.106, respectively, while positive association was found between HLA DQ2 and DR3 and CD. Frequency of HLA DQ2, DR3 and DR16(2) was higher in first-degree relatives than in the control group while a positive association was found between HLA DQ2 and DR3. A negative association was found between HLA DQ5(1) and DQ6(1) in coeliac patients from Vojvodina and their relatives, in addition to HLA DR11(5) in the group of relatives (RR=0.363,PF=0.232). These findings indicate the impact of the HLA testing for CD in clinical practice in order to rule out the possibility to CD in doubtful cases or in at-risk subjects.

The article presents results of in situ tests determining correlations between the depending parameters defined by a static plate – VSS test – E1 and E2, and obtained from the study LFG Dynamic Load Plate. Studies indicate that the determination of the correlation between the parameters characterizing the particle size distribution (Cc, Cu, D10, D20, D30, D60), and the compaction parameters obtained by examining the compaction of sand embankment (Evd, E1, E2, I0) is physically complex and hence extremely difficult.

This work presents the design of a regenerative three-phase switching rectifier with high power factor and control in dq0 coordinates implemented on DSP TMS320F2812 of Texas InstrumentsTM. The controls have used the Clark and Park transformations and the bilinear equation of Tustin, so that the design of the digitals controllers, carried through on the frequency domain, became it significantly simple. The DSP of last generation used allow the programming in a high level language. It can propitiate that the routines be understood, reused and or improved without great efforts. In general way, this will facilitate the sharing of the information for future designs. The main advantages associates are: robust control, excellent regulation of the DC voltage, energy regeneration, low harmonic distortion in the input currents and high power factor.
Este trabalho apresenta o projeto de um retificador trifásico regenerativo com elevado fator de potência e controle em coordenadas dq0 implementado no DSP TMS320F2812 da Texas InstrumentsTM. No controle foram utilizadas as transformações de Clark e Park e a equação bilinear de Tustin, de sorte que o projeto dos controladores digitais, realizado no domínio da freqüência, tornou-se significativamente simples. As equações de controle consideraram também todos os ganhos reais oriundos da implementação. Desta forma, os sistemas obtiveram boa representação física. O DSP de última geração utilizado permite que a programação seja realizada em linguagem de alto nível, o que pode propiciar que as rotinas sejam entendidas, reutilizadas e ou melhoradas sem grandes esforços. Até certo ponto isto facilitará o compartilhamento das informações para projetos futuros. As principais vantagens associadas são: controle robusto, excelente regulação da tensão do barramento CC, regeneração de energia, baixa distorção harmônica nas correntes de entrada e elevado fator de potência.

Abstract:

This master thesis is one part of a project, called “StabSim”, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system.

The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these. There is also a discussion whether the model can be reduced in order to receive a less stiff system.

To get a proper system the models needs many parameters. Some of them are unknown and that’s why this report includes methods to estimate them. Measurements have then been done on a main battle tank, and requisite parameters have been estimated.

Abstract:
This paper studies the effect of information disclosure on banks' portfolio risk. We cast a simple banking system into a general equilibrium model with trading frictions. We find that the information disclosure lowers the expected risk-adjusted profits for a non-negligible fraction of banks. The magnitude of this effect depends on the structure of the banking system and, alarmingly, it is more pronounced for systemically important institutions. We connect these theoretical findings to the stress test procedure, where bank information is disclosed by the regulator. The 2011 and 2014 stress tests are used in an empirical study to further support our theoretical results.

A doença celíaca (DC) é uma enteropatia imuno-mediada caracterizada por inflamação crônica do intestino delgado, que resulta em atrofia das vilosidades intestinais, hiperplasia de criptas e infiltração linfocitária. A doença ocorre em indivíduos geneticamente predispostos pela presença dos genes do sistema HLA DQ2 e/ou DQ8. Esses genes codificam as moléculas MHC de classe II presentes nas células apresentadoras de antígenos, que fazem apresentação antigênica aos linfócitos T, iniciando a resposta imunitária inflamatória presente na DC. Os genes HLA DQ2 e DQ8 são responsáveis por 40% da suscetibilidade genética da doença celíaca (DC), sua prevalência tem mostrado variações em diferentes regiões do mundo, e até o momento não foi determinada na população brasileira. Com base nestes dados, o presente estudo pretende estimar a frequência dos alelos HLA predisponentes para DC em um grupo populacional de recém-nascidos brasileiros. Os genes HLA-DQ2 e DQ8 foram tipados em 329 recém-nascidos pela técnica qPCR e os resultados foram confirmados por um kit comercial que utiliza a metodologia PCR-SSP. Os resultados revelaram uma prevalência de 33,44% para os heterodímeros DQ2 e DQ8, semelhante aos obtidos em estudos realizados nos países europeus. Em uma segunda análise dos dados, quando a presença de pelo menos um dos alelos predisponentes para DC foi considerado, observamos uma porcentagem aumentada dos alelos de alto risco para desenvolvimento de DC nos recém-nascidos brasileiros. Diante destes achados é possível concluir que os dados encontrados na população brasileira são semelhantes aos encontrados nos países europeus, embora as características populacionais sejam distintas, e que a metodologia empregada, e que foi validada e confirmada é confiável e poderá ser reproduzida facilmente em novos estudos. _______________________________________________________________________________________ ABSTRACT
Celiac disease (DC) is an immune-mediated enteropathy characterized by chronic inflammation of the small bowel which results in intestinal villi atrophy, crypt hyperplasia and lymphocyte infiltration. This disease only affects genetic susceptible individuals who carry the genes that integrate the HLA DQ2 and/or DQ8 system. These genes code for MHC class II molecules present in antigen-presenting cells, which will interact with T-lymphocytes leading to the characteristic inflammatory response of DC. Forty percent of the genetic susceptibility to DC is associated with class II HLA-DQ2 and -DQ8 genotypes. The prevalence of these genes has shown significant variations among different world regions and has not been previously determined among the Brazilian population. The aim of this study was to estimate the prevalence of celiac disease HLA-predisposing alleles in Brazilian newborns. DQ2 and DQ8 genes were typed in 329 newborns using qPCR and the results were confirmed by a PCR-SSP commercial kit. The prevalence of DQ2 and/or DQ8 heterodimers was 33.44%, which is similar to the results obtained in European screening studies. However, if only considering the presence of at least one of the CD predisposing alleles, an increased percentage of high-risk alleles could be observed among the Brazilian newborns. Analyzing our results, we could conclude that, the prevalence of DQ2 and/or DQ8 heterodimers in our population is similar to that observed in European population screening studies although the characteristics of both populations highly differ and that the applied technic proved to be reliable and can be easily reproduced in further studies.

A perspectiva de aumentar a produtividade do gado bovino a partir da aplicação de melhoramento genético do rebanho é cada vez mais estudada. Dentre as regiões genômicas mais estudadas e promissoras têm-se o Complexo Principal de Histocompatibilidade (MHC), já que este reúne genes importantes na resposta imunológica do animal, sendo possível selecionar marcadores nesta região para maior resistência a enfermidades e, portanto, maior produção pecuária. A diversidade do MHC bovino, conhecido como BoLA (Bovine Leukocyte Antigens), foi estudada inicialmente investigando seus genes isoladamente. A maioria dos bovinos são heterozigotos em BoLA e apenas em ocasiões especiais (animais homozigotos ou que possuam informação de pedigree) seu haplótipo pode ser caracterizado. Portanto, este trabalho objetivou desenvolver uma nova abordagem para descrever haplótipos de BoLA de vacas heterozigotas, utilizando células do trofoblasto de embriões partenogenéticos bovinos. Dois métodos para validação desta abordagem foram utilizados: um painel de 445 SNPs em BoLA foi informativo acerca do efeito que a recombinação meiótica apresenta na zigose da região; e a comparação de alelos de BoLA-DRB3 entre a fêmea bovina e sua célula trofoblástica partenogenética (CTP) demonstrou ser um método confiável e prático para a investigação de homozigose em BoLA. A partir de ambos os métodos, a metodologia desenvolvida aqui foi validada, já que CTPs homozigotas em BoLA foram derivadas de vacas heterozigotas, permitindo a descrição de haplótipos de BoLA. A análise detalhada da região de Classe IIa de BoLA-DRB3-DQA-DQB revelou a presença de 18 haplótipos distintos, sendo 16 destes nunca antes descritos. Além disso, dois alelos de DQA e um de DQB presentes nestes haplótipos são novos. O método descrito aqui foi mais eficiente do que a investigação por fêmeas homozigotas ou inferir a composição haplotípica baseada em informação de pedigree, além de evitar ambiguidades nos resultados. Novas pesquisas buscando a otimização deste método podem aumentar a sua eficiência e torná-lo mais facilmente aplicável a uma variedade de estudos genéticos, usando espécies diferentes e com finalidades distintas.
The prospect of increasing the productivity of cattle by means of genetic improvement is increasingly investigated. Among the most studied and and promising genomic regions is the Major Histocompatibility Complex (MHC), since it includes key genes of the immune response of the animals, being able to select makers in this region for increased disease resistance and therefore greater production. The diversity of the cattle MHC, known as BoLA (Bovine Leukocyte Antigens), has been primarily studied using variants of serological specificities or sequencing some of its genes. Most cattle are heterozygous at BoLA and only in special occasions (homozygous animals or animals for which pedigree information is available) can the haplotypes be characterized. Therefore, this study aims to develop a novel approach to describe BoLA haplotypes from heterozygous cows, using trophoblast cells from parthenogenetic bovine embryos derived from slaughterhouse ovaries. Two methods for validating this approach were used: a panel of 445 SNPs spanning BoLA region was informative on the effect of meiotic recombination on the region zigosity; and the comparison of BoLA-DRB3 alleles between the dam and its parthenogenetic embryo derived trophoblast cells (PEDTC) proved to be a reliable and practical method for investigating BoLA homozigosity. Using both methods, the approach presented here was validated, since BoLA homozygous PEDTC were derived from heterozygous cows, allowing the description of BoLA haplotypes. Detailed analysis of the BoLA Class IIa region identified 18 different BoLA-DRB3-DQA-DQB haplotypes, including 16 novel haplotypes. Furthermore, two DQA and one DQB alleles included in these haplotypes were novel. This method was more efficient than to look for homozygous cows or infer haplotype composition based on pedigree information, in addition to avoid ambiguities on the results. New researches aiming for the improvement of this method can increase its efficiency and make it more easily applicable for a variety of genetic studies, using different species and for other purposes.

Abstract:
As equações das máquinas de relutância chaveada nos eixos de referência dq0 são complexas. Esse fato faz com que o controle de torque de máquinas de relutância chaveada usando Controle Vetorial seja um processo árduo. Ao longo das décadas, modelos matemáticos usando fluxo concatenado e indutância como variáveis de estado e o método de Controle Direto de Torque foram desenvolvidos para contornar os problemas de complexidade mencionados. Neste artigo, propõe-se uma estratégia simples de controle de torque de máquinas de relutância chaveada usando Controle Vetorial. O método aqui apresentado utiliza a transformação dqx, que é uma generalização da transformação Park, e a derivada da indutância como variável principal. Os resultados de simulação mostraram que a oscilação do torque diminuiu 11 vezes e o fator de oscilação do torque diminuiu 13 vezes em comparação com o controle chaveado tradicional. Além disso, usando a estratégia proposta neste trabalho, o enfraquecimento e enriquecimento de campo se tornam simples e diretos, aumentando a flexibilidade de operação desse tipo de máquina. A formulação matemática, bem como os resultados teóricos e de simulação para uma máquina de relutância chaveada 6/4 são discutidos. Também são apresentados resultados de simulação para enfraquecimento e enriquecimento de campo.
