Full textThe present work has as purpose to develop a pizza base for a targeted customer suffering from the celiac disease, valuing by-products from the rice industry, namely flour of broken rice and rice bran. The aim of this study is to develop a mix, for pizza base, designed for home preparation, increasing the market supply of gluten-free products to lower the prices normally associated with this kind of products. Today Portugal can count with 15 permanent industries in rice milling (Ania, 2010). The by-products from the processing of the agro-industry raw materials from rice are usually considered as non-hazardous, abundant, easily biodegradable, cheap and potentially recoverable. However, there may be an economic problem, due to the large quantities processed, thus imposing a productivity burden significant in this sector. The production of gluten-free bakery products presents a technological challenge, due to the limited capacity of the gluten-free doughs in sustaining the CO2 produced during fermentation. We studied the effect of various ingredients added to the pizza dough. These studies were carried out at the level of texture - Texture Profile Analysis and Cutting test; rheology - test of stress and frequency sweep; aw (water activity), and the expandability of the dough throughout the fermentation (over-run percentage). A sensory testing was performed to the pizza bases with a panel of non-celiac tasters. From the results, the formulation F5 with 33% of rice bran and 4% of broken rice flour was emphasized, which led to better technological and sensory characteristics with rheological characteristics similar to commercial gluten-free pizza base. A comparison of nutritional formulation developed in this study was also performed with two commercial mixes, a gluten-free one and another whole meal with gluten

Full textBrazil, for structural conditions and national political is, import great amounts of wheat to use in the bread making. However, Brazil is considered one of the greater producing of soy and rice of the world. This way the use of soy and rice flours for bread making can be considered as a promising alternative for importing reduction of wheat. The aim of the work was study of technological and nutritional effects of the partial substitution of flour wheat for flour mixtures of rice and soy flours. In the study, flours had been valued flour mixtures of rice and defatted soy, were elaborated the fat in the ratios of 90:10, 80:20, 70:30, 60:40 and 50:50 that had substituted the flour of wheat in 10, 20, 30, 40 and 50%. The mixing flours had been chemical evaluated how much to protein texts, carbohydrates, ethereal extract, leached ashes, staple fibers and humidity, sensorially through the parameters of global evaluation and nutritionally through the rocking of nitrogen, biological value, digestibilidade, quotient of proteic efficiency, quotient of liquid proteic, glicemic index, cholesterol and HDL. The results indicate that the substitution of up to 30% of the flour of wheat for equality flour mixture of rice and taken away the fat soy improves the nutritional value of breads, without compromising its technological quality and its sensorial properties.
Questões estruturais e de política agrícola nacional fazem com que o Brasil seja um dos maiores produtores de soja e arroz do mundo, mas ao mesmo tempo, um dos maiores importadores de trigo, especialmente para emprego na panificação. Desta forma, a utilização de farinhas sucedâneas para panificação provenientes da soja e arroz pode ser considerada como uma alternativa promissora para diminuição das importações do trigo no país. Objetivando estudar efeitos tecnológicos e nutricionais da substituição parcial da farinha de trigo por misturas de farinhas de arroz e soja, foram testadas 25 formulações de farinhas mistas contendo farinha de trigo, arroz e soja desengordurada, respectivamente nas proporções de 90:9:1, 90:8:2, 90:7:3, 90:6:4, 90:5:5, 80:18:2, 80:16:4, 80:14:6, 80:12:8, 80:10:10, 70:27:3, 70:24:6, 70:21:9, 70:18:12, 70:15:15, 60:36:4, 60:32:8, 60:28:12, 60:24:16, 60:20:20, 50:45:5, 50:40:10, 50:35:15, 50:30:20 e 50:25:25. As farinhas mistas foram avaliadas quimicamente quanto aos teores de proteínas, carboidratos, lipídeos, cinzas, fibras e umidade, sensorialmente através dos parâmetros de avaliação global e nutricionalmente através de balanço de nitrogênio, valor biológico, digestibilidade, quociente de eficiência protéica, quociente de eficiência líquida protéica, glicemia, colesterol e HDL. Os resultados indicam que a substituição de até 30% da farinha de trigo por mistura igualitária de farinhas de arroz e soja desengordurada melhora o valor nutricional dos pães, sem comprometer sua qualidade tecnológica e suas propriedades sensoriais.

Full textDuring the change of fresh fruits for many manufactured products in industry, several coproducts are generated. In this context, studies have been carried on in order to investigate the nutritional value of these co-products, valuing them and suggesting new alternatives of use. Thus, the purpose of this study was to investigate the use of the seeds of guava (Psidium guajava L. var. Paluma) for the extraction of oil and also their potential use as flour in cookie formulation. Moreover, the phenolic content and antioxidant capacity of seeds were evaluated. After drying and grinding the guava seeds, they were used to determine the chemical composition and the characterization of both lipid and fatty acids profile present in the seeds. The analyses of phenolic content and antioxidant capacity by DPPH and FRAP methods were performed in nine extracts prepared with the seed. The guava seed flour was obtained by seed grinding and subsequent granulometric standardization, and then analyses of the physicochemical composition were performed. The viability of the use of seed as flour was verified through the production of cookies. Formulations with 10%, 30% and 50% of guava seed flour were developed, partially replacing the wheat flour. The cookies elaborated were evaluated regarding their chemical composition as well as physical, texturometric and color characteristics. The cookies sensory analysis, made with different guava seed flour concentrations, was performed by testing the ordering concerning the preference and acceptability. In addition, a review on the product purchase intention and the index calculation of acceptability were performed. The results showed the seed is a fiber-rich material, highlighting the high content of insoluble fiber. The highest oil yield was obtained for the cold extraction with a chloroform and methanol mixture. The fatty acids found in greater quantities for all the solvents used in the extraction were: the stearic, elaidic, linoleic and palmitic acids. However, the palmitic acid was absent in the extraction with petroleum ether. The hydromethanolic extract at a temperature of 50 °C exhibited both higher phenolic content and greater antioxidant capacity by the FRAP method. The guava seed flour presented humidity content according to the standard required by Brazilian law, and also high levels of protein, fat and dietary fiber, especially the insoluble fraction. The gradual addition of this flour to cookies increased lipid and dietary fiber content, and reduced humidity, carbohydrate and energy value. The weight and post-firing diameter, as well as cookies instrumental hardness increased according to the addition of guava seed flour, and their color became darker. The elaborated cookies presented acceptable sensory properties, and the percentage of substitution used in this study was accepted by the judges amongst all sensory attributes. In conclusion, the guava seed is an alternative ingredient for using a product that is usually discarded. The flour obtained from this co-product is an alternative to partially substitute wheat flour in cookies, in order to improve its nutritional value without interfering with the sensory characteristics.
Na indústria, durante a conversão das frutas in natura em produtos industrializados são gerados muitos coprodutos. Nesse contexto, estudos têm sido conduzidos com o intuito de investigar o valor nutricional desses coprodutos, valorizando-os e sugerindo novas alternativas de utilização. Assim, a proposta do presente trabalho foi estudar o aproveitamento das sementes de goiaba (Psidium guajava L. var. Paluma) para a extração de óleo e investigar o potencial de utilização das sementes como farinha na formulação de biscoitos. Avaliou-se ainda o teor de compostos fenólicos e a capacidade antioxidante das sementes. As sementes de goiaba, após serem secas em estufa e trituradas em micromoinho, foram utilizadas para a determinação da composição química, caracterização do teor de lipídios e do perfil dos ácidos graxos. As análises do teor de compostos fenólicos e da capacidade antioxidante pelos métodos de DPPH e FRAP foram realizadas em nove extratos elaborados com a semente de goiaba. A farinha de sementes de goiaba foi obtida pela moagem da semente e posterior padronização granulométrica, sendo então realizadas as análises da composição físico-químicas. A viabilidade de utilização das sementes como farinha foi verificada a partir da elaboração de biscoitos. Foram desenvolvidas formulações com 10%, 30% e 50% de farinha de sementes de goiaba em substituição parcial à farinha de trigo, os biscoitos elaborados foram avaliados quanto à sua composição química, características físicas, texturométricas e de cor. A análise sensorial dos biscoitos elaborados com diferentes concentrações de farinha de sementes de goiaba foi realizada por meio de testes de ordenação quanto à preferência e aceitabilidade. Realizou-se ainda a avaliação da intenção de compra do produto e o cálculo do índice de aceitabilidade. Os resultados mostraram a semente como material rico em fibras, destacando o alto teor de fibra insolúvel. O maior rendimento em óleo foi obtido para a extração a frio, com a mistura de clorofórmio e metanol. Os ácidos graxos encontrados em maior quantidade para todos os solventes empregados na extração foram o esteárico, o elaídico, o linoleico e o palmítico, porém este último ausente na extração com éter de petróleo. O extrato hidrometanólico à temperatura de 50 °C exibiu o maior teor de compostos fenólicos e a maior capacidade antioxidante pelo método FRAP. A farinha de sementes de goiaba apresentou teor de umidade em acordo com o padrão exigido pela legislação brasileira e valores elevados de proteína, lipídios e fibra alimentar, com destaque para a fração insolúvel. A adição gradual desta farinha aos biscoitos elevou os teores de lipídios e fibra alimentar e reduziu os de umidade, carboidrato e valor energético. O peso e o diâmetro póscocção e a dureza instrumental dos biscoitos aumentaram com o acréscimo de farinha de sementes de goiaba e sua coloração se tornou mais escura. Os biscoitos elaborados apresentaram propriedades sensoriais aceitáveis, sendo os percentuais de substituição utilizados neste estudo aceitos pelos julgadores, dentre todos os atributos avaliados. Conclui-se que, a semente de goiaba é um ingrediente alternativo para o aproveitamento de um produto normalmente descartado. A farinha obtida a partir deste coproduto é uma alternativa para a substituição parcial da farinha de trigo em biscoitos visando melhorar seu valor nutritivo sem interferir nas características sensoriais.

Full textMid-ocean ridges are a fundamental but insufficiently understood component of the global plate tectonic system. Mid-ocean ridges control the landscape of the Earth's ocean basins through seafloor spreading and influence the evolution of overriding plate margins during midocean ridge subduction. The majority of new crust created at the surface of the Earth is formed at mid-ocean ridges and the accretion process strongly influences the morphology of the seafloor, which interacts with ocean currents and mixing to influence ocean circulation and regional and global climate. Seafloor spreading rates are well known to influence oceanic basement topography. However, I show that parameters such as mantle conditions and spreading obliquity also play significant roles in modulating seafloor topography. I find that high mantle temperatures are associated with smooth oceanic basement, while cold and/or depleted mantle is associated with rough basement topography. In addition spreading obliquities greater than > 45° lead to extreme seafloor roughness. These results provide a predictive framework for reconstructing the seafloor of ancient oceans, a fundamental input required for modelling ocean-mixing in palaeoclimate studies. The importance of being able to accurately predict the morphology of vanished ocean floor is demonstrated by a regional analysis of the Adare Trough, which shows through an analysis of seismic stratigraphy how a relatively rough bathymetric feature can strongly influence the flow of ocean bottom currents. As well as seafloor, mid-ocean ridges influence the composition and morphology of overriding plate margins as they are consumed by subduction, with implications for landscape and natural resources development. Mid-ocean ridge subduction also effects the morphology and composition of the overriding plate margin by influencing the tectonic regime experienced by the overriding plate margin and impacting on the volume, composition and timing of arc-volcanism. Investigation of the Wharton Ridge slab window that formed beneath Sundaland between 70 Ma and 43 Ma reveals that although the relative motion of an overriding plate margin is the dominant force effecting tectonic regime on the overriding plate margin, this can be overridden by extension caused by the underlying slab window. Mid-ocean ridge subduction can also affect the balance of global plate motions. A longstanding controversy in global tectonics concerns the ultimate driving forces that cause periodic plate reorganisations. I find strong evidence supporting the hypothesis that the plates themselves drive instabilities in the plate-mantle system rather than major mantle overturns being the driving mechanism. I find that rapid sub-parallel subduction of the Izanagi mid-ocean ridge and subsequent catastrophic slab break o_ likely precipitated a global plate reorganisation event that formed the Emperor-Hawaii bend, and the change in relative plate motion between Australia and Antarctica at approximately 50 Ma

Full textThis work is a part of a collaboration program between Lebanese University and University of Rennes 1. The thesis is divided into two parts: fluorine chemistryv : synthesis of new heterocycles bearing fluorine-containing side chains ; medicinal chemistry : research towards new anticancer molecules. The first part consists of three chapters: in the first chapter, gem-difluoro enone-type intermediates were synthesized through a new route and their cyclocondensation reactions were studied to get pyrazolines and pyrrolines with fluorinated side chains. In the second chapter, type-chroman-4-one heterocycles were prepared using the previous difluorinated intermediates. In the third chapter, the Kinugasa reaction was applied for the first time on gem-difluoro propargylic derivatives. This reaction has allowed us to discover a pathway to a new family of molecules, the fluorine-containing exoalkylidene β-lactames. In the second part, our goal was to reinduce the proapoptotic properties in cancer cells in order to obtain new antitumor compounds. Starting from data obtained through molecular modeling studies, we designed and prepared several series of analogs for a known inhibitor (MIM-1) of the anti-apoptotic protein Mcl-1. Over 40 analogs have been synthetized and screened towards three types of cancer cells (breast, ovarian and melanoma). Some of these derivatives have demonstrated promising data in these areas

Full textDemands on state of the art deposition technologies for semiconductor production focus on uniformity, repeatability and low defectivity. The chamber condition is a key parameter to achieve these high demands in chemical vapour deposition (CVD) processes and are even more critical to the atomic layer deposition processes (ALD). During the deposition process not only the wafer surface but other chamber parts as well are covered with a thin film. This film accumulates during the deposition cycles and is prone to fall off the walls and pollute the wafer surface. The chamber parts that are exposed to the deposition must be set back to a steady state so that no deposits fall off the walls. The chamber condition also changes uncontrolled with varying film condition on the wall. A new approach for cleaning of ALD-titanium nitride (TiN) deposition chambers was investigated. To determine etch rates TiN-samples (created by ALD, CVD and PVD) were placed on a temperature controlled sample holder. An argon/NF3 mixture was excited in an upstream remote plasma source (RPS) and then routed through the reaction chamber. No further plasma activation inside the reaction chamber was done. The etching was monitored by in-situ reflectometry and etch rates were calculated. The effect of chlorine addition was also studied and strong influence on etch rates was found. The etch rate of TiN is dependent exponentially on temperature and very low etch rates were achieved below 70◦C at a chamber pressure ranging from 20-300 Pa. It was found that this correlates very well with the vapour pressure of the reaction product TiF4. At temperatures of 300◦C etch rates up to 800 nm/min were achieved. The optimum pressure for etching was found at 100 Pa while the pressure effect was small. The etch rate was mainly dependent on the availability of activated fluorine to create TiF4 by the reaction 2 NF3 → N2 + 6 F* 2 TiN + 8 F* → 2 TiF4 + N2 The NF3 decomposition to nitrogen and fluorine was monitored by quadrupole mass spectrometry (QMS) and was found to be greater than 96%. This figure allows an estimation of the amount of Global warm potential (GWP) gas emmited by the process for environmental considerations. Using argon/NF3 or argon/fluorine mixtures in RPS devices reduces the GWP emissions by more than 90% compared to RIE plasma cleaning with SF6. No etching occurred by using argon/chlorine only mixtures as no physical etch component was involved in RPS etch. However adding chlorine to the argon/NF3 mixture accelerated the etching process. Chlorine addition to the argon/NF3 mixture increased the etch rates up to 270% in the low pressure/low temperature regime. At higher temperatures or higher pressures the etch rates dropped below the etch rates achieved solely with fluorine chemistry. It must be emphasized that there is no physical acceleration of the ionized molecules toward the etched sample in this remote plasma setup. The usage of a remote plasma offers an alternative way to remove residues from chambers running TiN deposition processes. At high temperatures the Ar/NF3 offers remarkably high etching rates for TiN compared to other films (silicon nitride, -oxide, tungsten) usually cleaned by remote plasma. For low temperature applications the chlorine enhancement offers an interesting alternative to accelerate the etch process

This thesis is concerned with the introduction of quality daylight to buildings by means of translucency in the horizontal planes or floors within the building. Since people began to build, the concept of translucency in the vertical planes. the walls of a building, has served as the basis for continual invention in structural systems and the translucent component or window itself. This thesis pursues the application of translucent floor systems as an alternative or additional means of achieving daylighting in this same vein. This thesis begins by tracing and elaborating on the early historical precedence for this application. It then proceeds to explore the properties of the various types of daylight admitted through horizontal openings and its behavior in relationship to the properties of the translucent floor construction. Through a series of physical daylight modeling techniques. basic relationships are established between the parameters of the translucent floor system and the resultant quality and quantity of daylight in the building. The basic structural systems employed in this technology are investigated and evaluated with respect to translucency of the system. The compatibility of floor translucency to various programmatic and organizational characteristics of the building is assessed. This thesis concludes by demonstrating the application of the translucent floor system to achieving daylighting in three prototypical architectural projects covering a diverse range of building types.

Full textElectrically Induced Dynamic Processes in Liquid Crystals Investigated by Means of NMR --------------------------------------------------------- Within the thesis reorientation processes of thermotropic low molar mass nematic liquid crystals are described. Dynamic processes in external electric and magnetic fields are investigated by means of proton and fluorine NMR. A combination of different reorientation experiments with NMR methods allows the direct observation of the director dynamics on a timescale from 100 milliseconds to 100 microseconds. The first part provides a detailed description of the experimental setup. The reorientation experiments in the magnetic field of the NMR spectrometer are induced by high voltage pulses. The different parts of the high voltage supply are specified together with the synchronisation with the NMR experiment and several automation techniques. Some difficulties related to the usage of thin capacitor cells as NMR samples are discussed. The second part deals with different types of dynamic processes in nematic liquid crystals. The reorientation dynamics can be changed in a wide range by varying the electric excitation. Reorientation times down to 50 us are possible. Special time resolved NMR techniques provide the dipolar splitting and the chemical shift as a function of the orientational state. The proton linewidth changes in such an experiment from approx. 30 kHz to less than 300 Hz, the position of the fluorine chemical shift varies within a range of 10 kHz. These results yield a multitude of material parameters and provide information about the underlying dynamic process which may be e.g. homogeneous or inhomogeneous

Megamullions in slow-spreading oceanic crust are characterized by smooth "turtle-back" morphology and are interpreted to be rotated footwalls of long-lived detachment faults. Megamullions have been analyzed in preliminary studies, but many questions remain about structural and tectonic details of their formation, in particular how the hanging wall develops in conjugate crust on the opposing side of the rift axis. This study compares the structure of an off-axis megamullion complex and its conjugate hanging wall crust on the Mid-Atlantic Ridge near 27 0N. Two megamullion complexes, an older (Ml) and younger (M2), formed successively on the west side of the rift axis in approximately the same location within one spreading segment. Megamullion M1 formed while the spreading segment had only one inside comer on the west flank, and megamullion M2 formed after the segment developed double inside corners west of the axis and double outside corners east of the axis. The older megamullion formed between -22.3 and -20.4 Ma, and the younger megamullion formed between -20.6 and -18.3 Ma; they are presently -200-300 km off-axis. Reconstruction poles of plate rotation were derived and plate reconstructions were made for periods prior to initiation of the megamullion complex (anomaly 6Ar, -22.6 Ma), after the termination of megamullion Ml and during the development of megamullion M2 (anomaly 5E, -19 9 Ma), and shortly following the termination of megamullion M2 (anomaly 5C, -17.6 Ma). These reconstructions were used to compare morphological and geophysical features of both flanks at each stage of the megamullions' development. Megamullion Ml's breakaway occurred at -22.3 Ma and slip along this detachment fault continued and propagated northward at -20.6 Ma to form the northern portion of M2. The exhumed footwall of megamullion M1 has weak spreading-parallel lineations interpreted as mullion structures on its surface, and it forms an elevated plateau between the enclosing segment boundaries (non-transform discontinuities). There was an expansion southward of the detachment fault forming megamullion M2 at -20.1 Ma. It either cut a new detachment fault through megamullion Ml, stranding a piece of megamullion Ml on the conjugate side (east flank), or it linked into the active detachment fault that was forming megamullion M1 or propagated into its hanging wall. The expanded detachment of megamullion M2 and the termination of megamullion M1 occurred during a time when the enclosing spreading segment roughly doubled in length and formed two inside corners. Megamullion M2 developed prominent, high-amplitude (-600 m) mullion structures that parallel the spreading direction for more than 20 km at each inside corner. Its detachment fault was abandoned - 18.6 Ma in the south and ~18.3 Ma in the north ...

Full textSince 1990, networking and mobile technologies have made a phenomenal unprecedented progress. This progress has been experienced on multiple fronts in parallel; especially on the application level and the user's needs one. This rapid evolution of the technology imposed a need for the existence of heterogeneous environments where the coverage is ensured throughout the different available networks. The challenge with such architecture would be to provide the user with the ability to navigate through the different available networks in a transparent and seamless fashion. However, the navigation among different types of networks is commonly referred to as vertical Handover. The IEEE 802.21 standard offers a component that is called Media Independent Handover (MIH) which has a function that provides the capability of transmitting the state of the connection of the mobile nodes from the lower to upper layers. This layer would exist between layer 2 and layer 3 within the protocol architecture. The main role of MIH is to help the mobile node transfer without interrupt among different types of networks, but the logic of selection is left without implementation. In this context, we worked on the improvement of the Handover management by proposing a new architecture, called VHMC and based on MIH by offering new methods for selecting the destination network. The first solution is a new algorithm called Multiple Criteria Selection Algorithm (MCSA) based on multiple parameters of the quality of service. We used Network Simulator (NS2) for testing our approach and study the number of lost packets and lost time during Handover. The second solution is a new model for selecting the destination network based on fuzzy logic techniques. The distinctive characteristic of this model lies in the study of genuine Handover records taken from a Lebanese mobile operator called "Alfa". A third proposed solution for network selection is based on multiple linear regression theory

Full textPerfluorinated coatings used as anti-adhesive coatings in bread pans are subjected questions relating to their aging. In this context, the objective of this work was to focus on the consequences of aging of perfluoroalkoxy (PFA) coatings on their anti-adhesive performance. The consequences of loss of anti-adhesive properties were studied in terms of chemical risks and neoformed compounds in bread crust during baking in contact with a pan were investigated. To do so, pans were aged under industrial conditions, then a method was specifically developed for this study to measure forces during depanning step. Moreover, several bread formulas were tested. The aim was to determine the impact of physical state of lipids (rapeseed oil versus concrete fat) and of other components as proteins and fibers (by adding whole-wheat flour) on depanning step.Aging in industrial conditions seems to only affect physical properties (roughness) of PFA coatings. These modifications of the pan surface did not led to depanning problem at the end of the baking step. Moreover, the chosen reactivity markers evolve slightly with aging, whatever the bread formula used, even if a slightly increase of CML quantity with aged pan was highlighted.Furthermore, in order to characterize the adhesion of wheat dough depending on the temperature, a new methodology was developed. It consisted in measuring the adherence forces under experimental simulations on rheometer. We selected model glass surfaces which had chemical properties close to the properties of PFA coatings. We showed that adhesion and viscoelastic properties evolve in the same way with temperature, and interfacial properties also contribute to evolution of dough adhesion. Wheat dough tend to adhere more easily on hydrophilic surfaces. Anyway, on these surfaces, failure may become cohesive from a specific temperature, showing a decrease of the dough surface hydrophobicity

This thesis constructs a system identification procedure of building with mid-story isolation , expecting to identify physical parameters of a building with a simplified modal. We used lump mass method, simplifying a building with mid-story isolation into a four degree of freedom system. These degrees of freedom are superstructure, floor above isolation system, substructure and equivalent foundation. For the superstructure, concepts of effective modal mass and effective modal height are adopted to simplify multiple degree of freedom to single degree of freedom. Linear mechanical behavior is assumed in superstructure and substructure; nonlinear mechanical behavior is assumed in isolation story, following the Bouc-Wen modal. Besides, in equivalent foundation part, to describe the soil structure interaction system with the Soil Spring Method. Soil and structure is a simplified impedance between the spring and damping, and assume that the reaction is a non-linear response. We used Output-error method to identify superstructure’ s, substructure’s , Bouc-Wen modal in floor above isolation’s and equivalent foundation’s parameters. In numerical example, we considered structural calculation to evaluate four degree of freedoms’ stiffness and damping, and we input TAP089EW921 to state spacement to calculate the response of all degree of freedom. We used the response to identify the parameters. By numerical example, we hope to improve the accurate of the modal and the reasonable of the procedure. Finally, the reliability of present procedure was verified by calculating the error index between the measured data and identified results from new Civil Engineering Building at NTU

Abstract The objective of the research is to establish a system identification procedure of mid-story isolation building to identify the meaningful parameters of building with simplified building model. The research simplifies the mid-story isolation building as four degree of freedom system by using lump mass method. The four degree of freedom systems are superstructure, floor above isolation system, substructure and equivalent foundation, respectively. By using effective modal mass and effective modal height method, the multiple degrees of freedom system for superstructure are divided into single degree of freedom system. Assuming the mechanical behaviors of superstructure and substructure are linear, and the behavior of isolation story is non-linear; further, the behavior of isolation story is simplified from non-linear to bilinear behavior by using massing criteria. The damping of isolation story is assumed as non-linear damping in the research, the other freedoms are linear damping. As for the equivalent foundation, a set of equivalent damping and spring is adopted to simulate the soil-structure interaction of the mid-story isolation building, and the mechanic behavior of foundation is assumed as linear; finally, the Output-error method is applied to each degree of freedom to identify the linear parameter of superstructure, substructure and equivalent foundation, and the non-linear parameter of LRB. In numerical examples section, according to the 「Structural computation statement in the New Research Building of Civil Engineering department of Nation Taiwan University」, mass, stiffness, damping parameter of each degree of freedom can be estimated voluntarily. Following the research regards the ground acceleration of TAP089EW921 earthquake as input data, and then the Newmark’s linear acceleration method is used to obtain the behavior of each degree of freedom. Subsequently, regarding the behavior of each degree of freedom as measurement data, the identification procedure is executed to verify the suitability of identification theory and modified identification model. The data gathered by Strong Motion Instrumentation Program in the New Research Building of Civil Engineering department of Nation Taiwan University is adopted as measurement data to implement practical analysis, both the single and multi-section identification are accomplished and discussed in the research. Finally, the reliability of the identification procedure is verified by calculating the error indicators between the result of identification procedure and measurement data.

The culture of Chinese Academy was first established in the mid-Tang dynasty. For over a thousand years of development, it not only flourished into many Chinese literary sects, but also nurtured various political and academic talents for each dynasty. The rise and fall of Chinese Academy are commonly seen in each dynasty, and their management and teaching methods are almost always influenced by those in power under political factors. Nonetheless, the academic leadership of the Chinese Academy is unarguable. The traditional academies of Taiwan have gradually transformed into local constructions of Literary Temple due to the establishment of modern schools. However, the academies not only are the traditional place for education that have bred many talents for the country, but also possess a unique architectural style due to their particular function which render them value for cultural preservation. Through data collection and sites survey, five academies of the central Taiwan, Lan-Tain, Dou-Don, Min-Sin, Hwon-Si, and Xingxian, were chose for this study. of the historical background five Colleges: such as College, the structure generated by the flat facade, through the shape grammar parsing, moderate to clarify the spatial relationships between Specific contents and results were summarized as follows: A. Literature and case review Historical background, development, and achievement of these traditional academies of Taiwan were sorted out through literature references and data collection. Site survey and drawings for each academy in the study were prepared for the analysis of flat facade and the relationship of space interpretation, thus lead to the understanding of the spatial logic of the academy. B. Establishment of studies foundation From space planning principles compiled through data collections, the spatial composition of these traditional academies originated from "shrine" which derived symmetrically from obvious space axis. As the spatial structure of the principle of sorting out the central Taiwan College of shape grammar research to establish a research base. C. The establishment of the grammar rules and the actual deduction Construction of traditional academies axis characteristics of the symmetry axis, the shape of the Palladio plane uniaxial grammar rules, and legislation will go through grammar parsing the relationship between surface composition and its associated logic. Through analysis of the above theory and the shape grammar, this study strived to understand the developmental background, historical culture, and their meaning in modern era of these academies in central Taiwan, and to conclude the design principles and implications of space structure.

Full textElectrically Induced Dynamic Processes in Liquid Crystals Investigated by Means of NMR --------------------------------------------------------- Within the thesis reorientation processes of thermotropic low molar mass nematic liquid crystals are described. Dynamic processes in external electric and magnetic fields are investigated by means of proton and fluorine NMR. A combination of different reorientation experiments with NMR methods allows the direct observation of the director dynamics on a timescale from 100 milliseconds to 100 microseconds. The first part provides a detailed description of the experimental setup. The reorientation experiments in the magnetic field of the NMR spectrometer are induced by high voltage pulses. The different parts of the high voltage supply are specified together with the synchronisation with the NMR experiment and several automation techniques. Some difficulties related to the usage of thin capacitor cells as NMR samples are discussed. The second part deals with different types of dynamic processes in nematic liquid crystals. The reorientation dynamics can be changed in a wide range by varying the electric excitation. Reorientation times down to 50 us are possible. Special time resolved NMR techniques provide the dipolar splitting and the chemical shift as a function of the orientational state. The proton linewidth changes in such an experiment from approx. 30 kHz to less than 300 Hz, the position of the fluorine chemical shift varies within a range of 10 kHz. These results yield a multitude of material parameters and provide information about the underlying dynamic process which may be e.g. homogeneous or inhomogeneous.
