Повний текст джерелаNo presente trabalho investigou-se a flambagem local da mesa em perfis I de alma senoidal. Em uma primeira etapa, criaram-se pré-processadores no ANSYS 9.0, utilizandose a linguagem paramétrica do programa, para análise numérica não-linear de perfis I de alma plana e de alma senoidal. Analisou-se um grupo de perfis de alma plana e calibraramse os parâmetros da análise não-linear de forma a obter resultados numéricos consistentes com aqueles obtidos pelo processo de cálculo do projeto de revisão da NBR8800 (Set/2006). Utilizando-se os pré-processadores para perfis de alma senoidal e os parâmetros da análise não-linear calibrados nos modelos de alma plana, realizou-se um estudo paramétrico abrangendo geometrias associadas à faixa de aplicação dos perfis de alma senoidal. Os resultados numéricos obtidos foram comparados com os valores de resistência última obtidos por outros dois procedimentos: o processo de cálculo da NBR8800 para verificação de perfis I de alma plana e a proposta de dimensionamento de perfis de alma senoidal da fabricante austríaca Zeman, adaptado para a NBR8800. Observou-se que o procedimento da Zeman, adaptado para a NBR8800, é conservador. O procedimento da NBR8800, considerando kc=0,763 como coeficiente de flambagem da mesa, é consistente para o regime inelástico de flambagem da mesa e conservador para o regime elástico. Como resultado deste estudo, propõe-se um procedimento baseado no projeto de revisão da NBR 8800, adaptando-se a curva de verificação do regime elástico, de forma a atender aos resultados numéricos.

Повний текст джерелаConsiderations on perceptual information are quickly gaining importance in mesh representation, analysis and display research. User studies, eye tracking and other techniques are able to provide ever more useful insights for many user-centric systems, which form the bulk of computer graphics applications. In this work we build upon the concept of Mesh Saliency — an automatic measure of visual importance for triangle meshes based on models of low-level human visual attention—improving, extending and integrating it with different applications. We extend the concept of Mesh Saliency to encompass deformable objects, showing how a vertex-level saliency map can be constructed that accurately captures the regions of high perceptual importance over a range of mesh poses or deformations. We define multipose saliency as a multi-scale aggregate of curvature values over a locally stable vertex neighborhood together with deformations over multiple poses. We replace the use of the Euclidean distance by geodesic distance thereby providing superior estimates of the local neighborhood. Results show that multi-pose saliency generates more visually appealing mesh simplifications when compared to a single-pose mesh saliency. We also apply Mesh Saliency to the problem of mesh segmentation and view-dependent rendering, introducing a technique for segmentation that partitions an object into a set of face clusters, each encompassing a group of locally interesting features. Mesh Saliency is incorporated in a propagative mesh clustering framework, guiding cluster seed selection and triangle propagation costs and leading to a convergence of face clusters around perceptually important features. We compare our technique with different fully automatic segmentation algorithms, showing that it provides similar or better segmentation without the need for user input. Since the proposed clustering algorithm is specially suitable for multi-resolution rendering, we illustrate application of our clustering results through a saliency-guided view-dependent rendering system, achieving significant framerate increases with little loss of visual detail.

Повний текст джерелаClock meshes are a suitable clock network architecture for reliably distributing the clock signal under process and environmental variations. This property becomes very important in the deep sub-micron technology where variations play a main role. The clock mesh reliability is due to redundant paths connecting clock buffers to clock sinks, so that variations affecting one path can be compensated by other paths. This comes at cost of more power consumption and wiring resources. Therefore it is clear the tradeoff between reliably distributing the clock signal (more redundancy) and the power and resource consumption. The clock skew is defined as the difference in the arrival time of clock signal at clock sinks. The higher is the clock skew, the slower is the circuit. Besides slowing down the circuit operation, a high clock skew increases the probability of circuit malfunction due to variations. In this work we focus on the clock skew problem. We first extract some useful information on how the clock wirelength and capacitance change as the mesh size changes. We present analytical formulas to find the optimum mesh size for both goals and study how the clock skew varies as we move further away from the optimum mesh size. We also present a method for reducing the clock mesh skew by sliding buffers from the position where they are traditionally placed. This improvement comes at no increasing cost of power consumption since the buffer size and the mesh capacitance are not changed.

Повний текст джерелаHe objective of the Mesa Redonda Online business project is to be a viable alternative for the commercialization of various products that trade hands in the commercial quarter known as Mesa Redonda. We aim to satisfy the existing need of people who lack the time to do their shopping in person and prefer to shop online from the comfort of their home or office. That is why we propose the Mesa Redonda Online e-commerce platform, which will allow the commercial quarter’s customers and merchants to buy and sell through our mobile application. The first step involved market research, through which we identified the problem as well as its possible solution, which we then validated and verified through interviews and the implementation of a minimum viable product, whose results allowed us to define the development of the project. Furthermore, we developed a marketing plan aimed at being competitive. We implemented our own organizational structure according to the internal management model and designed an operations plan, applying management indicators, technical and organizational methods in order to carry out the development of our service, considering a five-year planning horizon. Finally, we applied the economic-financial plan to demonstrate through economic and financial indicators the feasibility of the project, in the short, medium, and long term. That led us to the conclusion that our business model is profitable.

Повний текст джерелаUppsatsens syfte är att visa på hur Svenska Spel bäst kan tänkas möta en eventuell liberalisering av den svenska spelmarknaden. Därmed vill vi konkretisera vilka strategier och organisationsförändringar de måste anamma för att bibehålla en stark position och vara konkurrenskraftiga även efter en regelreformerad marknad.
Bakgrunden till valet av studie är att det idag och de senaste åren hänt väldigt mycket till följd av ett allt mer globaliserat samhälle. Denna utveckling har bland annat lett till att det statligt reglerade monopolet av spelmarknaden kraftigt har ifrågasatts av såväl EU-kommissionen som av de konkurrenter som redan idag finns på den svårkontrollerade Internetmarknaden.
Uppsatsen inleds med en omfattande referensram, där Svenska Spels utgångspunkter idag utreds, samt hur utvecklingen på andra redan tidigare liberaliserade marknader har sett ut. Avsikten med detta är att ha denna information som ett komplement till den empiri som insamlats.
Empirin består dels av två respondenter, en från Svenska Spel, samt en av deras huvudkonkurrenter, Expekt. Empirin består även av en informant som är sakkunnig på konkurrensverket.
I analysen analyseras teorierna först separat enligt den ordningsföljd som ges av vår modell. Därefter vävs slutsatserna samman och presenteras kortfattat i en modell.
Vi finner i våra slutsatser att Svenska Spels idag är väl rustade inför en regelreformering. Troligen bäst av alla de aktörer som vill in på den svenska spelmarknaden. Detta då det mest sannolikt kommer att bli minst lika mycket regler även efter en liberalisering, och Svenska Spel redan idag har en organisation anpassad efter ett massivt regelverk.

Повний текст джерелаTime dependent simulations are still a challenge for industry, notably due to problems raised by moving boundaries, both in terms of CPU cost and accuracy. This thesis presents contributions to several aspects of simulations with moving meshes. A moving-mesh algorithm based on a large deformation time step and connectivity changes (swaps) is studied. An elasticity method and an Inverse Distance Weighted interpolation method are compared on many 3D examples, demonstrating the efficiency of the algorithm in handling large geometry displacement without remeshing. This algorithm is coupled with an Arbitrary-Lagrangian-Eulerian (ALE) solver, whose schemes and implementation in 3D are described in details. A linear interpolation scheme is used to handle swaps. Validation test cases showed that the use of swaps does not impact notably the accuracy of the solution, while several other complex 3D examples demonstrate the capabilities of the approach both with imposed motion and Fluid-Structure Interaction problems. Metric-based mesh adaptation has proved its efficiency in improving the accuracy of steady simulation at a reasonable cost. We consider the extension of these methods to unsteady problems, updating the previous fixed-point algorithm thanks to a new space-time error analysis based on the continuous mesh model. An efficient p-thread parallelization enables running 3D unsteady adaptative simulations with a new level of accuracy. This algorithm is extended to moving mesh problems, notably by correcting the optimal unsteady metric. Finally several 3D examples of adaptative moving mesh simulations are exhibited, that prove our concept by improving notably the accuracy of the solution for a reasonable time cost

Computational fluid dynamics (CFD) describes a method of numerically solving equations that attempt to model the behavior of a fluid. As computers have become cheaper and more powerful and the software has become more capable, CFD has become an integral part of the engineering process. One of the goals of the field is to be able to bring these higher fidelity simulations into the design loop earlier. Ideally, using CFD earlier in the design process would allow design engineers to create new innovative designs with less programmatic risk. Likewise, it is also becoming necessary to use these CFD tools later in the final design process to replace some physical experiments which can be expensive, unsafe, or infeasible to run. Both of these goals require the CFD codes to meet the accuracy requirements for the results as fast as possible. This work discusses several different methods for improving the accuracy of the simulations as well as ways of obtaining these more accurate results for the cheapest cost. In CFD, the governing equations modeling the flow behavior are solved on a computer. As a result, these continuous differential equations must be approximated as a system of discrete equations, so that they can be solved on a computer. These approximations result in discretization error, the difference between the exact solutions to the discrete and continuous equations, which is typically the largest type of numerical error in a CFD solution. The source of the discretization error is the truncation error, which is composed of the terms left out of the approximations made when discretizing the continuous equations. Thus, if the truncation error can be reduced, the discretization error in the solution should also be reduced. In this work, several different ways of reducing this truncation error through mesh adaptation are discussed, including the use of optimization methods. These mesh optimization methods are compared to a more common way of performing adaptation, namely equidistribution. It is determined that equidistribution is able to reduce the discretization error by a similar amount while being significantly faster than mesh optimization. This work also presents a framework for making the adaptation process faster overall by performing the adaptation on a coarse mesh and then refining the mesh enough to meet the error tolerance for the application. This framework was the cheapest method investigated to meet a given error target. This work also introduces a new technique called multi-mesh CFD, which allows each equation (conservation of mass, momentum, energy, etc.) to be solved on a separate mesh. This allows each equation to be solved on a mesh that is specifically adapted for it, resulting in a more accurate solution. Here, it is shown that, for certain problems, the multi-mesh technique is able to obtain a solution with lower error than only using a single mesh. This work also shows that these more accurate results can be obtained in less time using multiple meshes than on a single mesh.

Повний текст джерелаWireless Mesh Networks (WMNs) are wireless multi-hop networks built on wireless nodes that operate in an Independent Basic Set Identifier (IBSS) mode of the IEEE 208.11 wireless standard. IBSS is well known as an ad hoc mode which is found to build ad hoc wireless networks with the aid of routing protocols crafted to work in this mode. Ad hoc wireless mesh networks are always described as self-healing, self-configuring, easy to build, etc. However, these features do come at a cost because a WMN suffers performance degradation and scalability issues, which mainly come from the underlying IBSS mode that is used to form the physical network. Furthermore this is exacerbated by routing protocols in the upper layers which are intended to form a flat network architecture. Partitioning or clustering the flat network into smaller units has been proven to be a viable mechanism to counter the scalability problem in the communication network. The wired network for instance, presents a segmented, hierarchical architecture, where end user devices are organized in virtual local area networks (VLANs) using Ethernet switches and then Routers aggregate multiple VLANs. This thesis develops and evaluates a heterogeneous, clustering architecture to enhance WMN scalability and management. In the proposed architecture, the clustering is separated from the routing, where the clustering is done at the physical layer. At the routing level, each cluster is configured as a WMN using layer 2 routing for intra-cluster routing, and layer 3 routing for inter-domain routing between clusters. Prototypes for the proposed architecture have been built in a laboratory testbed. The proposed architecture reported better scalability and performance results compared to the traditional flat architecture.

O processo foi otimizado para a obtenção de materiais mesoporosos sem resíduos orgânicos e preparados em uma única etapa, eliminando assim, a longa etapa de remoção do surfactante na metodologia tradicional (tratamento térmico ou extração soxhlet, podendo durar dezenas de horas). A otimização do processo de pirólise de aerossol proposta nesta tese reduziu este tempo para apenas alguns minutos. Os materiais apresentaram uma área superficial (BET) de até 1028 m2 .g-1 , com volume de poros (BJH) de 0,58 cm3 .g-1 . Os difratogramas de raios-X indicaram um alto grau de organização com um arranjo hexagonal de poros, confirmado também pela microscopia eletrônica de transmissão. Além disto, bandas características de grupos orgânicos não foram observadas nos espectros de absorção na região do infra-vermelho para as amostras obtidas acima de 600ºC. Amostras dopadas com íons Eu3+ também foram preparadas durante a tese. A análise por espectroscopia de luminescência, para íons Eu3+ , indicou que o íon está encapsulado nos canais mesoporosos sem prévia modificação química da matriz. Posteriormente, moléculas de 1,10- Fenantrolina foram coordenadas ao íon Eu3+ aumentando a faixa espectral de excitação do íon (efeito antena). Além disto, partículas luminescentes também foram obtidas pela incorporação do complexo Eu(fod)3 ou rodamina-B nos poros das matrizes. Finalmente, testes de recobrimento (core shell, SiO2 mesoporoso-SiO2) das partículas luminescentes foram realizados e os resultados indicaram que independentemente da espessura obtida pelo processo de recobrimento, o grau de organização dos poros e a fotoluminescência não sofreram alterações
Spherical mesoporous silica particles were obtained using the template synthesis by spray pyrolysis process. The process was optimized for the preparation of the mesoporous materials in one-pot route without organic residues, eliminating thus, the long process of removal of the surfactant, usually used in the available methods (heat treatment or soxhlet extraction, which require several hours or days). The one- pot route proposed in this thesis reduced the extraction process to only a several minutes. These materials presented a surface area value (BET) of 1028m2 .g-1 and pore volume (BJH) was 0,58 cm3 .g-1 . The X-ray diffraction patterns and the transmission electronic micrographs show an ordered typical p6mm 2D hexagonal mesostructure. Characteristics bands of organic groups were not observed in the infra-red absorption spectra for the samples obtained at 600ºC. Moreover, SiO2 mesoporous doped with Eu3+ ions were also prepared. Luminescence data suggest that the Eu3+ ions were successful encapsulated into the channels of mesoporous silica without any preliminary chemical modification of the matrix. Moreover, extra ligands such as 1,10-Phenantroline can be further coordinated, increasing the spectral range excitation (antenna effect). Furthermore, luminescent particles were also prepared by the wet impregnation of Eu(fod)3 complex and rhodamine-B molecules. Finally, tests of coating (core shell, SiO2 mesoporous-SiO2) of luminescent particles had been carried through and the The results obtained show spherical shape and the observation of a highly ordered hexagonal array of mesochannels further confirms the 2D hexagonal p6m structure. Luminescence results reveal that rhodamine-B has been successfully encapsulated into the channels of mesoporous particles. Silica coating has been observed in TEM measurements

Posteriormente, moléculas de 1,10- Fenantrolina foram coordenadas ao íon Eu3+ aumentando a faixa espectral de excitação do íon (efeito antena). Além disto, partículas luminescentes também foram obtidas pela incorporação do complexo Eu(fod)3 ou rodamina-B nos poros das matrizes. Finalmente, testes de recobrimento (core shell, SiO2 mesoporoso-SiO2) das partículas luminescentes foram realizados e os resultados indicaram que independentemente da espessura obtida pelo processo de recobrimento, o grau de organização dos poros e a fotoluminescência não sofreram alterações
Abstract: Spherical mesoporous silica particles were obtained using the template synthesis by spray pyrolysis process. The process was optimized for the preparation of the mesoporous materials in one-pot route without organic residues, eliminating thus, the long process of removal of the surfactant, usually used in the available methods (heat treatment or soxhlet extraction, which require several hours or days). The one- pot route proposed in this thesis reduced the extraction process to only a several minutes. These materials presented a surface area value (BET) of 1028m2 .g-1 and pore volume (BJH) was 0,58 cm3 .g-1 . The X-ray diffraction patterns and the transmission electronic micrographs show an ordered typical p6mm 2D hexagonal mesostructure. Characteristics bands of organic groups were not observed in the infra-red absorption spectra for the samples obtained at 600ºC. Moreover, SiO2 mesoporous doped with Eu3+ ions were also prepared. Luminescence data suggest that the Eu3+ ions were successful encapsulated into the channels of mesoporous silica without any preliminary chemical modification of the matrix. Moreover, extra ligands such as 1,10-Phenantroline can be further coordinated, increasing the spectral range excitation (antenna effect). Furthermore, luminescent particles were also prepared by the wet impregnation of Eu(fod)3 complex and rhodamine-B molecules. Finally, tests of coating (core shell, SiO2 mesoporous-SiO2) of luminescent particles had been carried through and the The results obtained show spherical shape and the observation of a highly ordered hexagonal array of mesochannels further confirms the 2D hexagonal p6m structure. Luminescence results reveal that rhodamine-B has been successfully encapsulated into the channels of mesoporous particles. Silica coating has been observed in TEM measurements

Повний текст джерелаThis work presents a study about medical-volume segmentation and a solution to generate patient-specific meshes to use in patient-specific surgery simulations. Patientspecific meshes are useful assets for surgery planning and to allow better visualization of certain pathological conditions of a given patient, which are not obtainable by artistically designed meshes. We analyzed what are the complications to obtain a patient-specific mesh using only standard medical imagery exams. For that, we reviewed several medical volume segmentation techniques. It led us to define the problems within the existing techniques and to develop a method that does not suffer from these problems, with the least possible user interaction or relying on any other data other then the patient exam. Our target for obtaining specific meshes were soft tissue organs, which are a specially complicated case due to various issues related to the medical images and human anatomy. This is accomplished by geometrical operations over special meshes that deform until achieving the shape of the desired organ. Results show that our technique was able to obtain patient-specific meshes from medical images with superior quality than algorithms of the same class. Thanks to the simplicity of the developed approach, its also easy to implement and to reproduce our obtained results.
