Повний текст джерелаWorldwide regulations for short range communication devices allow the unlicensed use of several Gigahertz of bandwidth in the frequency band around 60GHz. This 60GHz band is ideally suited for applications like very high data rate, energy-autonomous wireless sensor networks or Gbit/s multimedia links with low power constraints. Not long ago, radio interfaces that operate in the millimeter-wave frequency range could only be realized using expensive compound semiconductor technologies. Today, the latest sub-micron CMOS technologies can be used to design 60GHz radio frequency integrated circuits (RFICs)at very low cost in mass production. This thesis is part of an effort to realize a low power System in Package (SiP) including both the radio interface (with baseband and RF circuitry) and an antenna array to directly transmit and receive a 60GHz signal. The first part of this thesis deals with the design of the low power RF transceiver front-end for the radio interface. The key building blocks of this RF front-end (amplifiers, mixers and a voltage controlled oscillator (VCO)) are designed, realized and measured using the 65nm CMOS technology of ST Microelectronics. Full custom active and passive devices are developed for the use within these building blocks. An important step towards the full integration of the RF transceiver front-end is the assembly of these building blocks to form basic transmitter and receiver chips. Circuits with small chip size and low power consumption compared to the state of the art have been accomplished.The second part of this thesis concerns the development of behavioral models for the designed building blocks. These system level models are necessary to simulate the behavior of the entire SiP, which becomes too complex when using detailed circuit level models. In particular, a novel technique to model the transient, steady state and phase noise behavior of the VCO in the hardware description language VHDL-AMS is proposed and implemented. The model uses a state space description to describe the dynamic behavior of the VCO. Its nonlinearity is approximated by artificial neural networks. A drastic reduction of simulation time with respect to the circuit level model has been achieved, while at the same time maintaining a very high level of accuracy

Resumo: Apresenta-se neste trabalho uma investigação experimental do comportamento da alvenaria estrutural de blocos de concreto, resistência à compressão axial e módulo de elasticidade, em função do emprego de blocos de diferentes resistências, na presença de grautes de resistências variadas e também da existência ou não de armaduras, aplicadas em distintas taxas. Desse modo, são apresentados e comentados os resultados de ensaios de compressão axial em unidades, prismas de três blocos e pequenas paredes, montados com um só tipo de argamassa, mas com blocos de duas resistências distintas, designadas B1 e B2. Os elementos ensaiados são vazios e também preenchidos com grautes de duas resistências, definidas G1 e G2. Além destes, também são ensaiados prismas e paredes armadas, com taxas de armadura ñ 1, ñ 2 e ñ 3. Portanto, são realizados ensaios em prismas e paredes vazias, prismas e paredes grauteadas com as diferentes combinações de classes de bloco e graute e com a combinação de blocos, grautes e taxas de armadura. Com os resultados obtidos foi verificado que o grauteamento praticamente dobrou a resistência do prisma grauteado, e, nas paredes o acréscimo foi médio de 80%, comparado com prisma e parede vazia na área bruta, porém esse aumento não foi proporcional à relação efetiva de áreas. Os prismas grauteados apresentaram diminuição na deformação de ruptura com a utilização de grautes mais rígidos, e, o grauteamento homogeneizou o comportamento de deformabilidade da alvenaria e do bloco que a constitui, no prisma e na parede. Constatou-se, também, que as armaduras não alteraram o comportamento estrutural dos prismas e paredes, nem na sua resistência à compressão axial e nem na sua deformabilidade.
Abstract: It is presented in this work an experimental investigation of the structural mansory of concrete blocks behavior, resistance to axial compression and elastic modulus, in function of the utilization of blocks of different resistances, with the presence of grout of varying resistances and the existance or not of armour, applied in distinct taxes. By this way, it's shown and commented the trials results of axial compression in units, three-block prisms and small walls, manufactured with just one type of mortar, but with blocks with two distincts resistances, called B1 and B2. The tested elements are empty and filled with grout of two resistances, defined as G1 and G2. Besides them, armoured prism and walls were tested too, with armour taxes called ñ 1, ñ 2 and ñ 3. Hence, the trials are executed in empty prisms and walls, grouted prisms and walls with the different combinations of classes of blocks and grouts and with the combination of blocks, grouts and armour taxes. With the obtained results, it was verified that the grout almost doubled the resistance of the grouted prism and, in walls there was an 80% increase, compared with empty prism and walls in brute area, although this increase was not proportional to the effective relation of areas. The grouted prisms presented a decrease in rupture deformation with the utilization of more rigid grouts, and the grout smoothed the deformability behaviour in mansory and in the block that form it, in prisms and walls. It was noticed too, that the armour do not alter the structure behavior of prisms and walls, not even in theirs resistance to axial compression force, neither to theirs deformability.

Повний текст джерелаAbstract: Given the substantial growth of structural masonry in Brazil, many concrete block companies have seen the need to optimize their production process, since more challenging projects require greater quality control. This study proposes to improve the production of concrete artifacts by means of simple optimizations that reduce costs and ensure the company's efficient production. Studying in depth the various parameters of the formation of dry concrete trace, such as cohesion, texture, density energy and axial compressive strength, all the particularities interdependent on one another become very complex when assessed in a single study. However, proposing a study that collects the information submitted by various authors, expedites optimizing and creating a research study which may assist in improving the dosage for dried concrete, particularly in the manufacture of structural blocks. In this study, some commonly used manufacturing equipment, such as concrete artifacts, were laboratory-adapted, enabling a direct correlation of the cylindrical specimens with the blocks. One of the adjustments is the study based on the standardization of compaction energy, provided by the mini-proctor testing equipment, thus simulating the vibro press machine. Other correlations such as cohesion and compressive strength were also obtained in the laboratory, therefore reducing the constant interferences in the plant's production process, observed in many other studies. In this manner, it was possible to reliably assess the results. The study was conducted in three stages, always seeking the highest compressed dry specific mass of the mixture of aggregates. In the first stage, only two aggregates were used (fine sand and pebbles), commonly used at the plant. The second stage included adding the coarse sand and stone powder to correct the lack of resistance promoted by the high amount of fine sand from... (Complete abstract click electronic access below)

Resumo: Atualmente, a construção em alvenaria estrutural toma como base para determinação da resistência das paredes, a resistência de corpos-de-prova prismáticos, constituídos por dois blocos. Este tipo de ensaio é especificado por norma, mas apresenta problemas já bastante conhecidos, como a alteração do valor de sua resistência devido ao confinamento causado pelos pratos da prensa. Esta mesma norma também especifica o ensaio de paredes em tamanho real, que são tão onerosos e de difícil execução, que são poucos os laboratórios capazes de realizá-los. Para complementar as indicações feitas pela norma brasileiras, os laboratórios de pesquisa utilizam outros tipos de corpo-de-prova, como o prisma de três blocos, que atende às necessidades de praticidade sem apresentar a inconveniência da alteração no valor de sua resistência devido ao confinamento pelos pratos da prensa. Mas este corpo-de-prova ainda está longe de representar fielmente a alvenaria final, sendo sua resistência maior que a da parede. Com o presente trabalho deseja-se investigar, de forma ampla, a resistência à compressão e a deformação da alvenaria estrutural de blocos de concreto, utilizando-se de diferentes tipos de corpos-de-prova, compostos por blocos e argamassas de diferentes resistências. Foram utilizados dois tipos de blocos e quatro tipos de argamassas. Estas últimas podem ser divididas, segundo à sua origem, em mistas e industrializadas. Para analisar a influência do tipo de argamassa, foi definido que uma das argamassas industrializadas tivesse resistência próxima a de uma das mistas. Os corpos-de-prova utilizados foram: prisma de dois blocos, prisma de três blocos, painel de (45x60) cm, painel de (90x100) cm e parede de (90x240) cm. Portanto, foram realizadas várias séries de ensaio, com a combinação dos três fatores condicionantes: geometria do corpo-de-prova, resistência... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Currently, the strength of the structural masonry is based on the strength of prismatic specimens, built by two blocks. This type of test is specified by a Brazilian standard, but it presents some problems, such as the alteration of its strength value due to the confinement caused by the machine plates. The same standard also specifies the test of walls in real size, but they are too expensive and its execution is very difficult, so few laboratories are able to carry them out. Trying to attenuate such reality, research centers use other types of specimens, such as the prism of three blocks, which is easy to build and doesn't present the inconvenience of the alteration of its strength value due to the confinement caused by the machine plates. But this kind of specimen is still far from representing, satisfactorily, the masonry: its strength is quite bigger than the masonry one. In this context, the present work aim to investigate, widely, the compressive strength and the deformation of the concrete structural masonry, using different types of specimens, built by blocks and mortars with different strengths. Two types of blocks and four types of mortars were used. These last ones can be divided, according to its origin, in mixing and industrialized. In order to analyze the influence of the type of mortar, it was defined that the strength of one of the industrialized mortar had to be next to one of the mixing. The specimens used were: prism of two blocks, prism of three blocks, panel of (45x60) cm, panel of (90x100) cm and wall of (90x240) cm. Therefore, many series of tests were carried out, with the combination of the three factors: type of specimen, block strength and mortar strength. The results were compared with values found in literature in order to conclude new trends or to reaffirm old theories about the efficiency interval of concrete structural masonry. The deformation was... (Complete abstract click electronic access below)

Повний текст джерелаMed FinFET-baserade applikationsspecifika integrerade kretsar (ASIC) -konstruktioner som ger löften om skalbarhet, prestanda och kraft är vägen framåt ojämn med tekniska utmaningar när det gäller att bygga effektiva ASIC: er. Formgivare kan inte längre lita på den "autoskalande" effektminskningen som följer teknisk nodskalning, i dessa tider då 7nm presenterar sig som en "långlivad" nod. Detta leder till behovet av tidig kraftanalys och reduktionsflöden som är integrerade i ASIC Intellectual Property (IP) designflöde. Detta leder till fokus på energieffektiv design förutom att det är funktionellt effektivt. Krafteffektivitetsrelaterade hotspots är de ledande orsakerna till respins av chip, och en riktlinjemetodik för att konstruera block på ett energieffektivt sätt leder till energieffektiv design av Integrated Circuits (ICs). Detta lindrar intensiteten hos kylbehovet och kostnaden. Common Memory-kontrollen är en av de ledande energikonsumenterna i ASIC-designen hos Ericsson. Denna avhandling fokuserar på att utveckla en effektanalys och reduktionsflöde för den gemensamma minneskontrollern genom att ansluta verifieringsmiljön för blocket till lågnivåeffektanalysverktyg, med hjälp av motiverade test caser för att samla effektmätvärden, vilket leder till två huvudmål för avhandlingen, karakterisering och optimering av blocket för kraft. Detta arbete inkluderar också energieffektivitetsperspektiv genom Differential Energy Analys-teknik, initierad av Qualcomm och Ansys, för att förbättra flödet genom att förbättra test cases som hjälper till att upptäcka effekteffektivitet / buggar och därför optimera blocket. Flödet som utvecklats i avhandlingen uppfyller målen att karakterisera och optimera blocket. Karaktäriseringsdata presenteras för att ge en uppfattning om vilken typ av data som kan samlas in och vara användbara för SoC-arkitekter och designers i planering för framtida mönster. Karaktäriserings/ profileringsdata som samlats in från blocken bidrar tillsammans till effektanalysen för elektronisk systemnivå som hjälper till att korrelera ASIC-effektberäkningen till kisel. Arbetet validerar också flödet genom att arbeta på ett specifikt underblock, identifiera möjliga effektbuggar, modifiera utforma och validera förbättrad prestanda och därmed validera flödet.

Resumo: O presente trabalho é uma reflexão sobre o processo da integração regional na Comunidade de Desenvolvimento da África Austral (SADC). Aborda os desafios e limites para o aprofundamento da integração, no período que vai desde a reestruturação da SADC em 2001 até à dificuldade de estabelecimento da União Aduaneira em 2010. Durante esse período, o processo de integração regional progrediu lentamente sem que houvesse distribuição igual de ganhos entre os países pertencentes ao bloco. Argumenta-se que a múltipla filiação dos Estados da SADC tem sido obstáculo para o aprofundamento da integração regional. Analisa-se os principais desafios para o aprofundamento da integração e desenha perspectivas para o futuro.
Abstract: This work intends to reflect on the process of regional integration in Southern African Development Community (SADC). It discusses the challenges and limits to the deepening of integration in the period from the restructuring of SADC in 2001 to the difficulty of establishing the Customs Union in 2010. During this period, the regional integration process has moved slowly and there was no equal distribution of gains among the SADC member states. The argument hereof sugests as the main obstacles to further integration: the multiple membership of SADC member states to the various regional blocs.

Resumo: Com a finalidade de contribuir para um melhor entendimento sobre a distribuição das ações verticais entre paredes de edifícios de alvenaria estrutural de blocos cerâmicos, foi desenvolvido no presente trabalho uma série de ensaios que visam a análise da eficiência de dois tipos de ligações usuais entre paredes: as ligações de amarração direta (contrafiada) e as ligações com amarração indireta, através de grampos metálicos e graute. Para a consecução desses objetivos foram desenvolvidos diferentes programas experimentais, que contemplaram desde a caracterização das propriedades mecânicas dos componentes da alvenaria (blocos, argamassa, graute e aço) até a ensaios em corpos-de-prova (paredes "H") representativos das formas de ligações em estudo. Com o objetivo de se encontrar correlações com estes tipos de ligações, foram desenvolvidos, em paralelo, ensaios de cisalhamento em unidades (blocos) e ensaios em prismas especiais, aqui chamados prismas cavaletes. Por fim, os resultados experimentais obtidos no presente trabalho foram comparados com os resultados encontrados em modelos reduzidos, nas escalas 1:3 e 1:5, obtidos da revisão bibliográfica.
Abstract: With the intend to contribute for a better understanding about the vertical loads spreading between the ceramic blocks walls of a structural masonry building, it was developed within the present work a series of tests aiming the analysis of the efficiency of two usual walls connections, one directly connected (stretcher, bond) and the other indirectly connected throughout steel staples and grout. For the attainment of these objectives it was developed different experimental programs, which contemplated since the mechanical properties characterization of the masonry componentes (blocks, mortar, grout and steel) until the tests on the studying connections representative specimen ("H" walls). Aiming to find the correlations for these types of connections, it was also developed, in parallel, shearing tests on the units (blocks) and tests on special prisms, called here by "rack prisms". At the end, the experimental results obtained upon the present work were matched with the found small-scale results, on the (1:3) and (1:5) scales, obtained from the bibliographic revision.

Resumo: O principal objetivo do trabalho foi desenvolver o estudo de ligações diretas entre paredes de blocos de concreto em escala real e reduzida 1A. Foram realizados ensaios de resistência à compressão axial e medidas as deformações em blocos, prismas e paredes nas duas escalas. Também foram montadas paredes em forma de H assentadas sobre bases de concreto armado. Estas foram construídas de 2 formas: na primeira, chamada de PRl, foram construídas 3 (três) unidades de modo que a parede central não possuísse apoio em sua base, com isso, todo o carregamento aplicado foi transferido para as abas. Na segunda forma, chamada PH2, foram montadas 3 (três) unidades, e ,nestas, a parede central ficou apoiada em sua base, dessa maneira, observou-se os efeitos de transferência de carga entre paredes, simulando uma estrutura real, onde geralmente todas as paredes da edificação são apoiadas em outras paredes ou em vigas baldrames. Na confecção dos corpos-de-prova, nas duas escalas em estudo, foi empregada uma argamassa industrializada usada comercialmente. O carregamento foi introduzido de forma centrada, e as deformações foram medidas através de relógios comparadores e de extensômetros elétricos. Para a análise dos resultados foram empregados testes estatísticos, validando estatisticamente as conclusões. Também foi empregada uma análise através de elementos finitos, simulando os ensaios experimentais realizados, comparando-se os resultados e readequando o modelo numérico. Os resultados obtidos permitiram uma avaliação da eficiência dos modelos numéricos empregados e os ajustes necessários nos mesmos, o entendimento da forma de transferência das ações verticais entre as paredes interligadas e as correlações entre as escalas estudadas.
Abstract: The main objective ofthis research was to develop a study of direct bond (stretcher bond) connections between walls of concrete blocks in real and 1:4 small-scale. In order to know the mechanical properties, it was accomplished shear and axial strength tests where it was also measured the strain in blocks, prisms and walls for both scales. It was executed walls in the "H" form supported by reinforced concrete base. These walls were done in two different ways, the first was called PRI, (with 3 specimens) it had no support in its central wall base, thus forcing that alI the load imposed to it was transferred to the lateral walIs throughout the connections. The second kind, which was called PH2, with also 3 specimens, was entirely support in its base. This was done in order to observe the load transference effects among walls simulating conventional structures, where all the walls are support over other walls or foundation beams. The specimens in both scales were made using industrialized mortar commercially used. The load was centralized imposed and strains were measurements by electrical displacement gages and strain gages. Statistical tests were used in the result analysis, statistically validating the conclusions. A finite element analysis was also used attempting to simulate the accomplished experimental tests, being this analytical model compared to the experimental results and then, by retrofitting the numerical analysis approaching their results. The obtained results allowed: an evaluation of the efficiency of the numeric models employed and the necessity of retrofitting the analysis; the comprehension in the way of transference of the vertical actions between the interlinked walls; and the correlations among the studied scales.

Resumo: Esta pesquisa foi realizada com o intuito de se conhecer, através de análise teórico- experimental, a distribuição das ações verticais ao longo da altura das paredes de um edifício em alvenaria estrutural cerâmica não armada em escala reduzida. O edifício em questão é formado por quatro pavimentos, blocos cerâmicos e lajes maciças estando apoiado sobre sistema de vigas baldrames e estacas, sendo que as estacas estão sobre um pequeno radier. Após obtenção dos resultados experimentais necessários, foram feitas análises teóricas da distribuição das ações verticais, utilizando-se dos modelos de cálculos atualmente conhecidos e também através de um software comercial baseado no Método dos Elementos Finitos. Fez- se comparações com os resultados obtidos através dos ensaios experimentais com o intuito de verificar qual modelo de cálculo melhor representou o comportamento da alvenaria. A fim de avaliar a distribuição das ações verticais, o edifício foi ensaiado através de carregamentos uniformemente distribuídos - bandejas com água - sobre as lajes dos diferentes pavimentos, medindo assim, os valores de reações de apoio nos pontos instrumentados. Como principal conclusão, verificou-se que para cálculos manuais de distribuição de ações verticais as paredes não devem ser tratadas como isoladas, mesmo para edifícios de pequena altura, com poucos pavimentos, mas como pertencentes a determinado grupo, por causa da existência de interação entre elas.
Abstract: This research was carried out in order to know, through theoretical and experimental analysis, the distribution of vertical loads along the height of the walls of a building in unreinforced structural masonry with ceramic blocks in small scale. The building in question consists of four floors, ceramic blocks and slabs being supported on system foundation beams and piles, the piles are upon a small raft. After obtaining the necessary experimental results were made theoretical analysis of the vertical loads distribution, using the currently model calculations and also with a commercial software based on finite element method. Comparisons were made with the results obtained from experimental tests with in order to determine which calculation model best represented the behavior of masonry. In order to evaluate the distribution of vertical loads, the building was tested by imposing uniformly distributed loads - trays with water - upon the slabs of different floors, thus measuring the values of support reactions at points instrumented. The main conclusion, it was found that for manual calculations of the distribution of vertical loads the walls should not be treated as isolated, even for buildings of small height, with few floors, but as belonging to a particular group, because of interaction between them.

Resumo: O presente trabalho teve como objetivo principal o estudo e o desenvolvimento das técnicas de produção de blocos de concreto para alvenaria estrutural na escala reduzida de (1:4). Os blocos em escala reduzida foram produzidos para apresentarem o mesmo comportamento em termos de resistência à compressão e deformabilidade que os seus pares em escala real. Para as duas escalas em estudo, (1:1) e (1:4), foram produzidos blocos com quatro traços diferentes entre si. Além dos blocos, também foram construídos e ensaiados à compressão prismas de três fiadas, nas duas escalas, de modo a determinar as correlações entre as resistências e deformações nas duas escalas. Para a consecução do objetivo acima, foram desenvolvidos ensaios de compressão axial em unidades e prismas de três blocos, nas escalas (1:1) e (1:4). Os parâmetros observados, medidos e comparados foram as resistências à compressão, os módulos de deformação, as curvas tensão-deformação e as formas de ruptura apresentadas pelos corpos-de-prova. Como resultado final, chegou-se a uma série de procedimentos que, quando observados, permitem a reprodução de blocos de concreto para alvenaria estrutural na escala (1:4), mantendo praticamente as mesmas características de resistência à compressão e deformabilidade, tanto para as unidades quanto para os prismas estudados.
Abstract: The present work had as main objective to study and the development of production techniques of the small-scale concrete blocks for structural masonry in the (1:4) reduced scale. The blocks in the small-scale were produced to present the same behavior in terms of compression strength and deformability as their equivalents in the full scale. For both studied scales, (1:1) and (1:4), blocks were produced in four different mixtures. Additionally to the blocks, it was built and tested three courses prisms, in both scales, in the way to establish the correlations between the compression strength and the deformations. To match the above objective, axial compression tests were developed in units and prisms, on the scales (1:1) and (1:4). The observed, measured and compared parameters were the compression strength, the strains, the stress-strain curves and the rupture forms presented by the specimens. As a final result, it was established a series of procedures that, when observed, allows the reproduction of the concrete blocks for structural masonry in the scale (1:4), keeping practically the same characteristics of compression strength and deformability, either for the units or for the prisms.

Повний текст джерелаRecently, the self-assembly technique provided an efficient and rapid pathway for obtaining nanometers structures in a nanometer scale using few steps of reactions and by means of simple physical attractions among macro chains, simulating the folding of peptide segments in proteins. The main characteristic of this technique is based on the chemical structure of the synthetic polymers which allow the self degradation process only with physical interactions between the macro chains (without covalent bonds). By the utilization of this technique is possible to obtain, easily and efficiently, nanometers structures, which would be difficult to be obtained by conventional techniques. The aim of this work was to study a chemical route for designing amphiphilic block copolymers and nanoparticles that exhibit thermo and pH responsive by means of self-assembly method. For this purpose, amphiphilic block copolymers were synthesized using as hydrophobic segment Poly(hydroxybutyrate-co-hydroxyvalerate) (PHBHV) and as hydrophilic segments, Poly(N-isopropylacrylamide) (PNIPAAm) and Poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAAmAA). The hydrophilic polymers, called \"smart\" polymers were synthesized by a new mechanism of controlled radical polymerization, the reversible addition-fragmentation chain transfer (RAFT). These nanoparticles sensitive to temperature and pH were utilized in a drug delivery system of a model drug, the Dexametasone acetate (DexAc) under controlled environment of temperature and pH. The results allowed identifying a chemical route for the synthesis of stimuli-responsive amphiphilic block copolymers by means of coupling reactions of a biodegradable polymer obtained from renewable resources with smart polymers. It was also possible to demonstrate the possibility of utilization of these amphiphilic copolymers in the preparation of nanoparticles by self-assembly technique as well as the utilization of this system in the encapsulation and in the drug delivery of a model drug with variation of temperature and pH.
