Повний текст джерелаA high-resolution, multi-level, primitive equation ocean model is used to examine the response of an eastern boundary oceanic regime to both wind forcing and irregular coastline geometry. The focus of this study is the coastal region from 300 N to 42.50 N, a portion of the Canary Current System (CCS). To study the generation, evolution, and sustainment of the currents, meanders, eddies and filaments of the CCS, the model is forced from rest using seasonal climatological winds. To investigate - the role of irregular coastline geometry, the first experiment uses climatological wind forcing along an idealized "straightened" coastline, while the second experiment uses the same wind forcing along an irregular coastline. In both cases a surface current, undercurrent, meanders, eddies, and filaments are generated. The results obtained while using the irregular, rather than the idealized coastline, however, show preferred eddy generation locations as well as enhanced growth of meanders, eddies, and filaments. The features produced by the model are consistent with available observations of the CCS. The model results support the hypothesis that both wind forcing and irregular coastline geometry are important mechanisms in the generation of many of the observed features of the CCS

Повний текст джерелаMuch has been researched in South Africa about the trauma of losing one&rsquo
s home, one&rsquo
s community and rebuilding one&rsquo
s life in a new environment. Several books have been published tracking the lives of the forcibly removed and their responses to leaving District Six. My research focuses on a different group namely those who had been forcibly removed from the centre of Stellenbosch, called &ldquo
Die Vlakte&rdquo
during that time. Living and working with and among people who have experienced this removal, I was keen to research whether the impact of the trauma is currently 
manifesting in this specific community and if so, what the symptoms would be. This qualitative inquiry focuses on one particular individual, Mr. Hilton Biscombe. I selected him because he, who experienced the removal as a teenager, spent most of his later life determinedly collecting stories and documents relating to this incident. Mr. Biscombe is also the only person of whom I am aware who responded personally through compiling a book, making a DVD, writing poetry as well as an autobiography relating to this event. My inquiry into the ways trauma manifests in a narrative, will be based on two interviews: one conducted by a white man from the University of Stellenbosch thirty years after the event
and another interview, six years later, conducted by myself.Our understanding of trauma is usually associated with a death or injury or the possibility thereof, but it could also include the victim&rsquo
s response to extreme fear, serious harm or threat to 
family members. According to van der Merwe and Vienings, people also become traumatized when witnessing harm, physical violence or death or the sudden loss or destruction of a victim&rsquo
s home (van der Merwe &
Vienings, 2001). So the issue of trauma is not in question, nor the fact that forced removals cause trauma. I am exploring testimony in the form of interviews for possible current manifestations of this trauma thirty-six years down the line.

Повний текст джерелаA Corrente do Brasil (CB) é provavelmente a Corrente de Contorno Oeste (CCO) menos estudada dos oceanos mundiais. A sua estrutura vertical única es faz dela uma CCO diferente em termos de velocidade e transporte. Apesar dos avanços significativos na última década, a variabilidade da CB na Bacia de Santos (BS, 23°S-28°S) ainda é pouco conhecida, apesar do papel estratégico da região na matriz energética brasileira. A CB se espessa mudando a sua estrutura vertical e muda sua estrutura dinâmica no domínio da BS. Na região de Cabo Frio (23°S) a corrente tem cerca de 500 m de profundidade. Ao sair da BS na região do Cabo de Santa Marta (28°S) a corrente se estende até cerca de 1300 m. Estas variações na espessura da corrente e consequente diferença no cisalhamento vertical de velocidade ocorrem devido à presença da Corrente Sul Equatorial em nível intermediário na região gerando a Bifurcação de Santos (BiS). Neste trabalho investigamos a variabilidade subinercial da CB na Bacia de Santos usando primeiramente dado alimétrico e um conjunto de análise espectral. Foram depois estudados fenômenos geradores dessa variabilidade com dados quasi-sinóticos do um cruzeiro oceanográfico CERES V do conjunto IOUSP-PETROBRAS. Foram identificados fenômenos diferentes no norte e sul da Bifurcação de Santos e esta diferença é provavelmente devido à presença da bifurcação ou à mudança que esta causa na estrutura da CB. Ao norte da BiS foi identificada uma oscilação com período de 92 dias e comprimento de onda de 490 km explicando um quinto da variabilidade da CB em 25°S. A oscilação de 92 dias está relacionada com ondas de vorticidade não lineares originadas a leste da corrente em ~35°W e se propagam zonalmente até ao eixo da corrente. Estas ondas perturbam a corrente originando oscilações com mesmo período e que propagam ao longo do eixo da corrente. Ao sul da BiS (~27°S) foram identificados dois máximos no espectro κ - ω. Os máximos correspondem a oscilações com período (comprimento de onda) de 68 e 148 dias (397 e 790 km). A onda com maior comprimento de onda é também uma onda de vorticidade de primeiro modo baroclínico não linear propagando para oeste com velocidade de fase de ondas de Rossby não dispersivas. Estas ondas são originadas no interior da bacia oceânica e seu sinal foi identificado chegando até 5°W. A onda de 68 dias existe apenas no domínio da CB. Esta onda propaga fase num eixo aproximadamente paralelo à CB e são detadas de forma clara apenas entre ~27°S e ~32°S. Esta onda explica uma variância da CB de ~21% ao longo do seu eixo. Observações quasi-sinóticas permitiram mapear um anticiclone e um ciclone associado a essa onda. Os vórtices aparentam uma estrutura modal muito semelhante à da corrente.

Повний текст джерелаLa structure laminaire du neocortex est universelle. Au-delà de petites variations dans la structure et la composition cellulaire, l`organisation des 6 couches corticales est conservé à travers tout les mammifères. Pourtant, la fonction des différentes couches corticales est largement inconnue. Ici, nous examinons si les sources et puits de courent observés durant làctivité neuronale spontanée sont distribués de façon aléatoire dans les couches corticales ou si des motifs reproductibles peuvent être observé. Pour examiner cette question, nous avons enregistré des potentiels de champs locaux (LFP) avec une électrode linéaire positionnée perpendiculaire à la surface corticale de làire S1Fl du cortex somato-sensoriel du rat. Afin d`éliminer l`impact de la référence électrique commune, la densité de sources de courent (CSD) a été calculé à partir des LFP. De plus, le CSD a été filtré dans les bandes classiques de EEG. Ensuite, afin de réduire la dimensionnalité des données, lànalyse des composantes principales (PCA) a été appliqué. Finalement, les composantes temporelles indépendantes (tICA) ont été calculées pour chaque bande de fréquence en utilisant làlgorithme FastICA. La reproductibilité du motif laminaire fût testée pour chaque composante.Nos résultats suggèrent des motifs laminaires de dipôles de source de curent qui sont reproductible à travers les différentes sessions et sujets. Pour la majorité des bandes de fréquence, la contribution maximale à l`énergie du signal vient des couches 4, 5a et 5b. La profondeur des dipôles dépend de la bande de fréquence. Dans la bande delta (1-4 Hz), le dipôle majeur est situé dans la couche 6. Dans la bande theta (5-8 Hz) et alpha (9-14 Hz), les dipôles reproductibles sont situés dans les couches 4, 5a et 5b. Dans la bande beta (15-30 Hz) un dipôle a été observé dans les couches 5a et 5b. Finalement, dans la bande gamma (30- 50 et 50-100 Hz), le dipôle majeur est situé dans les couches 3 et 4.Nos résultats suggèrent que les sources et puits de curent observées durant làctivité neuronale spontanée présentes de motifs laminaires reproductibles et ne sont donc pas aléatoires. Nos supposons que ces composantes indépendantes reflètent des contributions séparées du thalamus et des autres régions corticales.

Повний текст джерелаNeste trabalho desenvolve-se uma técnica para determinação da componente longitudinal do campo elétrico gerado por uma densidade superficial de corrente. A metodologia proposta baseia-se na diádica de Green da região em consideração, sendo estudadas regiões interiores em que existe uma solução analítica da equação de onda escalar em coordenadas ortogonais e regiões exteriores, em sistemas de coordenadas esféricas e cilíndricas. Para cada uma das soluções, mostra-se a convergência da expressão obtida para a componente longitudinal do campo elétrico, expressa por uma série ou integrais de funções modais. Baseado na metodologia desenvolvida, elabora-se um modelo de análise para determinação de campos e impedância característica em cabos coaxiais de seção arbitrária. O modelo é aplicado a cabos de seção circular e retangular. A metodologia de determinação de campos por diádicas de Green é ainda aplicada à análise de cabos coaxiais de seção retangular, com estais de fixação do condutor interno, localizados periodicamente.
It is developed a method for the determination of the longitudinal component of the electric field generated by a surface current density in the interior or the exterior regions. The proposed method is based on the dyadic Green´s function of the region under consideration, beeing analysed interior regions, assuming the knowledge of the analytical solution for the scalar wave equation in the orthogonal coordinate systems and external regions, using spherical and cylindrical coordinate systems. For the each solution, it is shown the convergence of the expression obtained for the longitudinal component of the electric field. Based on the developed method, a model of analysis is elaborated to determine the field and the characteristics impedance of coaxial cables of arbitrary cross section. The model is applied to cables with circular and rectangular sections. The dyadic Green´s function method is finally applied to the analysis of coaxial cables with internal metallic struts periodicaly placed.

Повний текст джерелаUK: АНОТАЦІЯ Дисертацію присвячено підвищенню показників маневреності кар’єрних самоскидів з електромеханічною трансмісією. Вперше науково обґрунтовано можливість та доцільність застосування примусового управління обертанням задніх ведучих коліс кар’єрного самоскида з електромеханічною трансмісією, що дозволяє їм виконувати маневри із використанням силового довороту. Вперше розроблено математичну модель силового довороту, яка дозволяє визначити відношення кутових швидкостей задніх ведучих коліс окремо правого і лівого борту машини і її показники маневреності відповідно до коефіцієнта зчеплення на основі вперше встановлених аналітичних залежностей. Аналітична залежність відношення кутових швидкостей задніх ведучих коліс від коефіцієнта зчеплення доведена методом лабораторного експерименту на створеній лабораторній моделі, яка дозволяє моделювати процес виконання маневру колісною машиною при різних способах повороту. Створено алгоритм примусового управління обертанням задніх коліс кар’єрного самоскида, оснащеного електромеханічною трансмісією. Відповідно до розробленого алгоритму управління виготовлено електронний блок, який разом із додатковою датчиковою апаратурою, що встановлюється на кар’єрний самоскид БелАЗ-7513В, представляє собою систему примусового управління поворотом.
RU: АННОТАЦИЯ Диссертация посвящена вопросу улучшения маневренности карьерных самосвалов с электромеханической трансмиссией для повышения эффективности их работы в стесненном пространстве рабочих зон глубоких карьеров. В работе проведен комплекс теоретических, лабораторных, промышленных исследований маневренности карьерных самосвалов с электромеханической трансмиссией при выполнении маневров с применением силового доворота. Разработана математическая модель силового доворота колесной машины. Впервые установлена аналитическая зависимость отношения угловых скоростей задних ведущих колес отдельно правого и левого борта от коэффициента сцепления, которая позволяет разработать рациональный алгоритм принудительного управления вращением задних колес карьерного самосвала. Впервые установлены аналитические зависимости, позволяющие определить показатели маневренности колесной машины на основе требуемого отношения угловых скоростей задних ведущих колес. Математическое моделирование с использованием разработанной модели позволило установить, что для карьерного самосвала БелАЗ-7513 минимальный радиус поворота в сложных условиях эксплуатации (на увлажненном грунтовом покрытии основных трасс с коэффициентом сцепления φ=0,34) при выполнении маневра с использованием силового доворота может быть уменьшен с 13,0 до 10,1 м. Установленные математические зависимости проверены экспериментальным путем с применением лабораторной модели, созданной в соответствии с масштабным коэффициентом, равным 12,0, в качестве которого выступало отношение радиуса колеса карьерного самосвала к радиусу колеса модели. Лабораторная модель позволяет моделировать процесс выполнения маневра колесной машиной при различных способах поворота путем принудительного воздействия на частоты вращения электродвигателей задних колес. Разработан и реализован на карьерном самосвале БелАЗ-7513В в условиях ПАО «Центральный ГОК» алгоритм принудительного управления вращением задних колес карьерного самосвала с электромеханической трансмиссией. Отклонение между расчетным 100 % (1,12 м) минимальным радиусом поворота лабораторной модели и полученным в результате эксперимента составило 10,7 % (1,0 м), отклонение между расчетным 100% (10,38 м) минимальным радиусом поворота карьерного самосвала и полученным путем промышленных испытаний составило 7,9 % (11,30 м), что подтвердило соответствие аналитических и экспериментальных показателей. Использование системы принудительного управления поворотом на карьерных самосвалах с электромеханической трансмиссией позволяет повысить техническую производительность машин на 6,1 % путем уменьшения времени их маневрирования до 1,4 мин, установленного с помощью хронометража в промышленных условиях, а также позволяет снизить топливо-энергетические затраты на 2,3 %. Материалы диссертационных исследований приняты на предприятиях ПАО «Центральный ГОК», ПАО «АрселорМиттал Кривой Рог» и ООО «Кривбасс-БелАЗ-Сервис СП». Расчетный экономический эффект в условиях ПАО «АрселорМиттал Кривой Рог», полученный за счет повышения производительности карьерных самосвалов БелАЗ-7513 на 5,9%, для существующего парка из 8 машин составил 678,0 тыс. грн. / год. Таким образом, впервые научно обоснованы возможность и целесообразность применения принудительного управления вращением задних ведущих колес карьерного самосвала с электромеханической трансмиссией при маневрировании, что обеспечивает уменьшение радиуса поворота машины, повышая производительность промышленного автотранспорта карьеров.
EN: THE SUMMARY The thesis is dedicated to increasing of open pit trucks with electrical transmission indices of maneuverability. For the first time there has been scientifically grounded possibility and suitability of usage of forced controllability of rear leading wheels of open pit truck with electrical transmission that enables them to carry out maneuvers with the usage of a forced additional turn. For the first time there has been worked out mathematical model of a forced additional turn which enables to determine a correlation of angular velocity of rear leading wheels of starboard and port sides of a car and its indices of maneuverability relative to a friction coefficient on the basis of firstly determined analytical dependence. Analytical dependence of relation of rear leading wheels angular velocity to a friction coefficient has been proved with laboratory experiment method on a created laboratory model which enables to simulate the process of a wheel vehicle maneuver performing with various means of a turn. An algorithm of a forced controlling of rear wheels rotation of open pit truck with electrical transmission has been created. In accordance with the created algorithm an electrical block which coupled with additional sensor equipment that is installed on a pit truck BelAZ-7513B representing a forced turn controlling system has been manufactured.

It is shown that the improvement of the quality and service life of technological chromium-containing galvanic baths is possible due to the operation of membrane electrochemical devices. The method of voltammetry with linear potential deployment was used as a study of the electrolitic reduction of metal ions present in the chromium-containing solution. Polarization curves the dependences of the magnitude of the current on the level of applied voltage for the cathodic release of cadmium and zinc at different temperatures. Polarization curves show a decrease in overvoltage in the presence of Zn2+ ions, the presence of Cd2+ ions contributes to a significant polarization of the cathode, and an increase in temperature reduces the polarization of the cathode. The presence of cadmium and zinc in the cathode deposit, the ions of which were present as impurities in the anolyte, was confirmed by electron microscopy with the functions of X-ray microanalysis. Polarization curves and electron microscopy methods established the transfer of ions through the cation exchange membrane between the anode and cathode chambers of this membrane electrochemical device. The optimal pH range of values electrochemical module cathode chamber for the release of metallic cadmium and zinc at the cathode has been established. In the result of statistical processing of experimental data, the regression equation of environment change of cathode chambers of electroreduction of cadmium and zinc in the mass transfer of data of metal ions through a cation exchange membrane RALEX®CM-PES 11-66 of the electrochemical module has received.The experimentally and statistically confirmed pH range in the range of 1.5-1.8 allows obtaining in the form of valuable products metallic cadmium and zinc, which can be used in metallurgy in contrast to their mixture of hydroxides in galvanic settlers. As a result, the conducted researches laboratory model of the membrane electrochemical device has developed, the regularities of mass transfer of Zn2+ and Cd2+ ions through the cation exchange membrane RALEX®CM-PES 11-66 had experimentally investigated.Thanks to experimental research, it has become possible to create new industrial electrochemical devices that can effectively regenerate the contents of technological baths. In the course of work, the regularities of influence of the following factors on the process of membrane electrolysis were studied: concentration of polluting metal ion, current density, temperature and hydrodynamic conditions of the near-membrane zone of the anolyte. The conditions for effective regeneration of galvanic solutions have been experimentally established. The effect of the concentration of the metal ion contaminant in the catholyte at a stable temperature and current density on the cathode yield of the metal was determined experimentally. Experimental studies were also performed at constant concentrations of pollutant metal ions in anolytes and variable current densities or different values of system temperature. Particular attention was paid to the use of forced mechanical stirring of the membrane zone of the anolyte. The increase of mass transfer through the cation exchange membrane RALEX®CM-PES 11-66 in the process of electrolysis due to the increase of the concentration of the contaminating ion in the anolyte, the increase of the temperature, and the increase of the current density on the membrane is proved. As a result of theoretical and experimental generalizations, the current limit density for simulated solutions of cadmium and zinc galvanic coatings passivations are determined. The increase of metal yield up to 50% as a result of forced mechanical mixing was established.The results of experimental studies have been analyzed mathematically. As a result of improving the known mathematical model, the kinetic parameters of research results with changes in the concentrations of contaminating ions of passivation baths and with changes in hydrodynamic conditions had established, instantaneous rate constants of cathodic electrodeposition of cadmium and zinc had found. Statistical analysis of research results is described adequately by the laws of membrane electrolysis by regression equations. The constructed equations of direct regressions of experimental researches had checked by regression and correlation analyzes. In the process of regression analysis, the coefficients in the regression equations were specified. Correlation analysis showed the different closeness of the relationships as a result of finding Pearson's correlation coefficients, which indicates the approximation of some experiments to both linear correlation and vice versa. As a result of general mathematical processing of the experiments results from data with changes in concentration, current density, temperature, and different hydrodynamic conditions, multifactor regression equations of membrane cathode electrodeposition of cadmium and zinc had constructed. Statgraphics Centurion 18-64X was used to find multifactor regression equations. The multifactor regression equations, obtained for the first time, show the share of influence of each variable factor by means of the corresponding coefficients. According to the constructed models, the influence of each variable factor on the electrical reduction processes of cadmium and zinc was determined. Thus constructed mathematical models allow to effectively carry out regeneration of passivating solutions by regulating the influence of variable factors on the process. The statistical significance of multifactorial regression equations was confirmed by the criteria of Student, Fisher, and Darbin-Watson. The industrial electrochemical device, allowing to regenerate effectively the structure of technological passivation baths of cadmium and zinc galvanic coatings, has been created in the result of introducing the experimental and mathematical researches in the industrial conditions. The structural dimensions and operating parameters of the industrial electrochemical module are established The adequacy of multifactor regression mathematical models of cadmium and zinc electroreduction has been practically confirmed on real passivation production baths. As a result of industrial implementation and operation of membrane electrochemical devices, in addition to effective purification of these process baths from Cd2+ and Zn2+ ions, the regeneration process of hexavalent chromium ions from Cr3+ ions has been theoretically and experimentally proved. Based on the analysis of information sources and the use of titrometric and photocolorimetric analyzes, the presence of chromate ion regeneration process at the lead anode was established in industrial experimental conditions, in technological baths of passivations of cadmium and zinc galvanic coatings. An experimental study of the anodic regeneration process confirmed the gradual increase in the concentration of hexavalent chromium ions and the gradual decrease in the concentration of Cr3+ ions in the passivation baths of galvanic coatings. As a result of the conducted researches, the efficiency of chromate regeneration was established at the level of 0.6-1.59 g / l per day in working passivation baths with a volume of 150 l. The reduction of the ecological danger level of passivation baths as a result of long-term operation of electrochemical modules in them due to constant regeneration of chromates had practically established. This process led to a decrease in the total concentration of chromates. It is proved that the operation of the created membrane electrochemical devices reduces the load on the treatment facilities of the galvanic section. The constant anodic regeneration of chromate anions installed during the operation of the electrochemical modules made it possible to create high-quality conversion chromate films on the surface of cadmium and zinc galvanic coatings and to save sodium dichromate. Due to the formation of chromates directly in the passivating baths, the need to often add sodium dichromate from the outside has disappeared. The reduction of working concentrations of sodium dichromate in technological baths from 100 - 200 g / l to 30 - 50 g / l had established due to its reaction with a coating of parts and removal to washing baths, which as a result allowed to reduce their ecological danger by 3.75 times. The calculation procedure on the ecological and economic efficiency of the electrochemical devices operation has been applied for the first time. Thanks to the calculations, the effectiveness of the created industrial modules of electrochemical in technological baths of passivation of cadmium and zinc galvanic coatings is shown. Experimental and statistical researches, their verification in industrial conditions of real factory galvanic production, and also the introduction of technological processes electrochemical regeneration of chromium-containing technological galvanic solutions in JSC Sumy plant "Nasosenergomash" (appendices Д, E, Ж), allow recommending to use this membrane electrolysis method for regeneration industrial chromiumcontaining technological solutions of our country.

Повний текст джерелаMedicinal plants constitute an unfailing source of compounds (natural products – NPs) utilised in medicine for the prevention and treatment of various deceases. The introduction of new technologies and methods in the field of natural products chemistry enabled the development of high throughput methodologies for the chemical composition determination of plant extracts, evaluation of their properties and the exploration of their potentials as drug candidates. Lately, metabolomics, an integrated approach incorporating the advantages of modern analytical technologies and the power of bioinformatics has been proven an efficient tool in systems biology. In particular, the application of metabolomics for the discovery of new bioactive compounds constitutes an emerging field in natural products chemistry. In this context, Acronychia genus of Rutaceae family was selected based on its well-known traditional use as antimicrobial, antipyretic, antispasmodic and anti-inflammatory therapeutic agent. Modern chromatographic, spectrometric and spectroscopic methods were utilised for the exploration of their metabolite content following three basic axes constituting the three chapters of this thesis. Briefly, the first chapter describes the phytochemical investigation of Acronychia pedunculata, the identification of secondary metabolites contained in this species and evaluation of their biological properties. The second chapter refers to the development of analytical methods for the identification of acetophenones (chemotaxonomic markers of the genus) and to the dereplication strategies for the chemical characterisation of extracts by UHPLC-HRMSn. The third chapter focuses on the application of metabolomic methodologies (LC-MS & NMR) for comparative analysis (between different species, origins, organs), chemotaxonomic studies (between species) and compound-activity correlations

The first purpose of this study is to investigate the efficacy of the different current patterns frequently used in electric current computed tomography (ECCT) for making the resistivity images. The second purpose is to characterize the relationship between surface voltage and current patterns. The third purpose is to present an experimentally adaptive method for the best current patterns. The last purpose is to propose the mathematical models for describing the phenomena of electrodes and compare with the experimental results. Based upon the above evaluations, the newly developed technique of ECCT is validated in depth. In this dissertation, the modalitiesand basic principles for the currently available computed tomography (CT) are briefly reviewed so as to compare with the ECCT. The historical development for the ECCT is also mentioned. Then, a system with 32 independent channels of current generators called Adaptive Current Tomography (ACT) for use in this study is described. Three current patterns are compared for their spatial resolution based upon two measures: maximum voltage difference and distinguishability. The current patterns studied are trigonometic current patterns, and a single current applied between an abjacent pair of electrodes and between an diametrically opposite pair of electrodes. The theoretical values of distinguishability and voltage difference for three current patterns are also found in excellent agreement with the experimental data. An experimentally adaptive scheme for obtaining the best current pattern is demonstrated. The eigencurrents of pseudo operator R, which characterizing the surface voltages and currents, are proved to be the trigonometric functions for the homogeneous and concentric inhomogeneous cases. Two methods using different currents are presented for obtaining their corresponding characteristic resistances. Comparing the signal-to-noise ratio as well as the image quality for the proposed currents, it is shown that the trigonometric currents are the best one among all the proposed currents. Finally, the mathematical models for electrode are described and proved with the experimental results. In summary, the trigonometic current patterns are better choice except the adaptive currents for electrical impedance imaging. An appropriate electrode models should be incorporated into the forward solver for improving the spatial resolution of images. Funture investigations in ECCT are also anticipated in the conclusion. 本研究之主要目的,第一是探討電流式電腦斷層掃描技術裡常用的各種電流之效用, 第二是建立體表電壓與電流圖型間的特徵關係,第三是提出適應實驗法以推得最佳電 流圖型,第四是建立一套完整的電極數學模型。 論文中首先扼要地回顧現有之傳統電腦斷層掃描技術的種類與基本原理;包括X光, 放射性,超音波和核磁共振;同時說明電流式電腦斷層掃描技術之進展與特性。本研 究所用的實驗設備為一具有32個電流產生器的適應電流式斷層掃描系統。 比較三種常用的電流圖型:空間三角凶暴電流圖型,對邊對電流圖型與相鄰對電流圖 型,實驗結果顯示,依最大壓差值來衡量,則可分辨的中心物直徑大小分別是9mm, 23mm,和79mm;以分辨值來判斷,則其直徑分別為9mm, 10mm ,和30mm。從適應實驗 法所得的結果,證明此法在推演中心物或離心物的最佳電流圖型皆可行與有效。對於 均質態與同心異質態,其擬運算子R 的特徵電流,理論推得為空間三角函數;至於特 徵電阻則可由直接測量法與傅氏分解計算而得,不過結果顯示前者較為準確。比較多 種電流圖型對雜訊的敏感度實驗數據,說明使用空間三角函數電流圖型,所測得的電 壓雜訊比最高。直接比較以兩種電流組所重建之電阻係數影像品質,更進一步說明三 角函數電流組在製作電阻抗影像為佳。最後,從理論推導而建立一完整電極數學模型 ,並由實驗加以證實。 總之,空間三角函數電流組,在製作電阻係數影像時,確實比其他電流組為優;但最 好是使用最佳電流組。再者,正向解法中當結合適當的完整電極數學模型,以提高影 像的解析度。最後,從本研究中,我們亦展望未來電流式電腦斷層技術之系統改良與 應用的方向。 論文共分十章,第一章回顧現有電腦斷層系統,第二章實驗系統說明,第三章提出拉 住演最佳電流圖型的實驗方法,第四章比較不同電流所產生的空間解析度,第五章建 立體表電壓與電流之特徵關係,第六章比較不同電流所產生之測量誤差,第七章比較 不同電流所重建之影像品質,第八章說明電極數學模型,第九章討論與結論,參考文 獻列於第十章,最後是兩則附錄,分別說明影像重建模擬程式與電極上電壓與電流分 佈之初步數學推導。

In this thesis, a new microwave component named current driver is proposed, which is capable of inducing ground edge current for radiation. Since the current driver serves as a small feeding structure with little contribution to radiation, it can be designed very small while good radiation properties are maintained. Compared to the miniaturized antennas, the approach that utilizes ground plane as the main radiation has smaller size and better antenna performance. Furthermore, a circuit model of the miniaturized balun (balanced to unbalanced transformer) is introduced to explain the current inducing mechanism and to provide some valuable physical insights into the properties of the current driver. The effect of a shielding metal box for the proximity circuitry near the current driver is also investigated. It is shown that the nearby shielding box has minor effect on the performance of the driver, which demonstrates the feasibility of the current driver for antenna applications in a compact wireless terminal. Given the benefits shown above, two antenna applications based on the current driver are presented. Both of them are fabricated on the low cost FR4 substrate of 0.4 mm. First, the current driver for WLAN 2.4 GHz designed with a lumped capacitor or printed capacitor has a small size of about 4 mm × 4 mm. The good radiation properties are obtained at 2.45 GHz with the measured radiation efficiency over 60 % and the nearly omni-directional radiation pattern with the average gain of about 0 dBi. Secondly, the dual-band current driver for WLAN 2.4/5/2 GHz applications is achieved by combining two single-band current drivers with the overall size of about 8.5 mm × 4 mm. The measured radiation performances at 2.4 GHz are similar to the ones for the previous single 2.4 GHz current driver, which has the measured antenna radiation efficiency higher than 60 % and nearly omin-directional patterns. At 5.2 GHz, the measured radiation efficiency is reduced to about 50 % due to the high dielectric loss caused by the FR4 substrate in the high frequency. The nearly omni-directional patterns are still maintained. The simulation and measurement results come to a great agreement. Based on the compactness and design flexibilities, the current driver is feasible for wireless applications

Abstract Magnetic reconnection usually takes place in a current sheet that separates two plasma regions having an antiparallel magnetic field component. Magnetic reconnection can lead to the formation of reconnection layers, where magnetic energy is conversed to plasma kinetic/thermal energy and magnetohydrodynamic (MHD) shocks and discontinuities are formed. In a hot plasma, such as in the solar corona or solar wind, the heat conduction effects should be considered because the conduction timescale is comparable to or shorter than the Alfvén timescale. In this thesis, the effects of heat conduction and magnetic guide field By in the magnetic reconnection layer is studied by solving one-dimensional Riemann problem for the evolution of an initial current sheet with an antiparallel component of magnetic fields on the two sides. In the numerical simulations, a dissipative MHD code with heat conduction and magnetic resistivity is used. First, the By effects on the current sheet evolution is considered in the resistive MHD. The initial magnetic fields across the initial current sheet is set to be B(z) = −Bxotanh(z/delta) +By +Bz , where Bx0 is the antiparallel component. In the symmetric case with By = 0, a pair of slow shocks are formed. For By ≠ 0 cases (even for a very small By), it is found that a pair of slow shocks and a pair of time-dependent intermediate shocks (TDISs) are formed. Notice that TDIS is not present in the By = 0 case. It is apparent that the case with By = 0 is a singular case. The plasma density and pressure increase and the magnetic field decreases across TDIS. It is further found that the rotation angle of tangential magnetic field across TDIS, Δphi, develops with time and gradually reaches its final value. It obeys Δphi(final) = 90°–phi∞, where phi∞ = tan-1(By/Bx) is half of the rotation angle of tangential magnetic field across the initial current sheet. Both pressure and temperature downstream of the slow shock decrease with phi∞, and increase with plasma beta∞. Second, the structure of slow shocks in the presence of a heat conduction parallel to the local magnetic field is studied. It is found that the slow shock consists of two parts: the isothermal main shock and foreshock. Significant jumps in plasma density, velocity and magnetic field occur across the main shock, but the temperature is found to be continuous across the main shock. The foreshock is featured by a smooth temperature variation and is formed due to the heat flow from downstream to upstream region. The plasma density downstream of the main shock decreases with time, while the downstream temperature increases with time, keeping the downstream pressure constant. It is shown that the jumps in plasma density, pressure, velocity, and magnetic field across the main shock are determined by the set of modified isothermal Rankine-Hugoniot conditions. It is also found that a jump in the temperature gradient is present across the main shock in order to satisfy the energy conservation. Third, the structure of slow shocks and intermediate shocks in the presence of a parallel heat conduction for an initial current sheet with By≠0 is studied. As before, a pair of slow shocks and a pair of TDISs are formed, and each slow shock consists of two parts: the isothermal main shock and the foreshock. The foreshock is found to reach a steady state with a constant width in the slow shock frame. The TDIS initially can be embedded in the slow shock’s foreshock structure, and then moves out of the foreshock region. With an increasing By, the propagation speed of foreshock leading edge tends to decrease and the foreshock reaches its steady state at an earlier time. Both the pressure and temperature downstream of the main shock decrease with increasing By. The present results can be applied to the shock heating in the solar corona and solar wind.
