NoC-based MPSoCs can provide massive computing power on a single chip, achieving hundreds of billions of operations per second by employing dozens of processing cores that communicate over a packet-switched network at a rate that exceeds 100 Tbps. Such devices can support the convergence of several appliances (e.g. HDTV, multiple wireless communication standards, media players, gaming) due to their comparatively high performance, flexibility and power efficiency. Due to the vast designspace alternatives, evaluating the NoC-based MPSoCs at lower abstraction levels does not provide the required support to find out the most efficient NoC architecture considering the performance constraints (e.g. latency, power) of a given application at early design process stages. Thus, NoC-based MPSoCs design requires simple and accurate high level models in order to achieve precise performance results, of each design alternative, in an acceptable design time. In this context, the present Thesis has two main contributions: (i) development of abstract NoC models, providing accurate performance evaluation; and (ii) integration of the proposed models into a model-based design flow, allowing the designspace exploration of NoC-based MPSoCs at early stages of the design flow.
Sintetizar em hardware uma dessas soluções ainda é uma tarefa extremamente custosa (DOPPA; ROSCA; BOGDAN, 2019). Seguindo essa linha, sintetizar todas essas possibilidades e atender ao time-to-market é uma tarefa inviável. Dentre as técnicas usadas para possibilitar a redução do tempo de exploração do espaço de projeto (DSE – do inglês DesignSpace Exploration) para sistemas computacionais está a predição do custo em área, potência e desempenho das possíveis soluções no espaço de projeto. Modelos de predição incluem técnicas de aprendizado de máquina e reduzem a quantidade de sínteses e simulações necessária, pois possibilitam a estimativa ou classificação de novos valores a partir de um conjunto de dados de treinamento (O’NEAL; BRISK, 2018). Essa técnica consolidada é encontrada em diversos trabalhos na literatura (ÏPEK et al., 2006; OZISIKYILMAZ; MEMIK; CHOUDHARY, 2008) e possibilita descobrir rapidamente soluções próximas do ótimo, satisfazendo aos múltiplos objetivos do sistema (KIM; DOPPA; PANDE, 2018).
Current design flow. At present moment, design of many RTLS is based solely on prototyping. Developers typically select a communication technology and several algorithms for location estimation. By performing series of real-world tests (e.g., by trying different movement patterns, or changing transmit power) they intend to calibrate the prototype and come up with an optimal configuration. The choice of technology and localization method, therefore, is done empirically at the very beginning of development and afterwards designers stick to that decision. If the latter is incorrect, it might entail the development of a new prototype. Designers do not have sufficient tools to try out different alternatives without violating time-to-market or running out of budget because prototyping might be both expensive and time-consuming. At the same time, real- world experiments are of crucial importance, because it is impossible to consider and predict all possible factors and events in a model. What we are trying to emphasize is that an intermediate stage between specification and prototyping is required, which would highly increase the designspace exploration quality and designer's confidence on their decisions. Such stage could include building models of different system configurations, simulating them and analyzing results using some verification techniques. The latter could be used in a feedback loop and affect the design in the sense of adjusting several model parameters for further simulations.
The performance and costs caused by these NoCs strongly depend on NoC-specific parameters like topology (Neuen- hahn et al., 2006), data word length, routing-algorithm and many more (Bjerregaard and Mahadevan, 2006). These NoC-parameters span a huge design-space for NoCs. As each application or application-class has different commu- nication requirements the appropriate NoC-parameter com- bination that fulfills these requirements at minimal costs has to be found (Ahonen et al., 2005; Benini, 2006).
approximations, usually quadratic, that model the objectives based on the given designs. The hope is that these designs will form a near convex hull around the feasible design re- gion. The RS approach helps to reduce the complexity of the optimization problem. Provided the designspace is not highly irregular, it is usually hoped that the RS models can model the global optima adequately. Regression analysis us- ing least squares is usually used to fit the polynomial curves to the data. If n terms are chosen for the polynomial model, then the number of design points required to construct the model should be at least 1.5*n. For a problem with a high number of design variables, it becomes very expensive for available computing resources. This problem is often re- ferred to as the curse of dimensionality. Additional work might need to be done to construct the RS models depend- ing on the nature and size of the problem. For regular and relatively small design spaces, the choice of points can be made using a variety of simple techniques to construct near- convex hulls (Giunta et al., 1995). For larger problems with irregular spaces, other statistical techniques from the design of experiments domain are needed, an example would be the D-optimality criterion.
2.2 Design de exposição, uma modalidade projetual Para Lorenc, Skolnick e Berger (2010), o design de exposição tem o objetivo de contar uma história sobre o significado de um conceito ou tema, um objeto, um espa- ço, um evento, uma figura histórica, uma empresa e seus produtos, e assim por diante. A informação interpretati- va é mais frequentemente expressa sob a forma de expo- sição, que é composta de um local, artefatos físicos, ima- gens, meios audiovisuais e conta, muitas vezes, com re- cursos interativos. Quanto aos tipos de exposição, no que se refere à natureza e objetivos, Locker (2011) classifica as exposições genericamente como de fins comerciais ou culturais. Ainda de acordo com Locker (2011), inde- pendentemente da natureza, é a ideia de comunicar uma história em determinado espaço tridimensional que atua como elo entre estes ambientes muito diferentes.
According to the characteristic of associative classification, a new class based frequent pattern mining strategic is designed in CACA to cut down the searching space of frequent pattern. OR-Tree structure enables the synchronization of the traditional phases which may not only simplify the associative classification but help to guide the rule generation and speed up the algorithm. And the redefinition of the redundant rule and compact set guarantee the usage of the compact set to help improve the classification efficiency and rule quality won’t affect the accuracy of CACA. Experimental result shows that, CACA is more competitive on accuracy and efficiency among associative algorithms.
A bíblia da arte é o documento composto por arte conceptual de todos os elementos do jogo, desde personagens, objectos, cenários, menus e animações; a bíblia da história consiste numa extensão da história incluída no design document com pormenores das personagens e do seu passado, sendo essencial na produção do software pois “uma vez criada a bíblia da história,quando o artista pretende aprender mais acerca da personagem que está a modelar, ele pode-se virar para a bíblia e descobrir acerca da infância daquelas personagens.” (Rouse III, 2004); a bíblia técnica funciona como complemento directo do design document ao expor através de algoritmos toda a estrutura gráfica, sonora e interactiva do jogo.
O Design “não é uma regra universal de configuração, mas uma ação interpretativa, criadora, que permite diversas formas de expressão” (BONFIM, 1999, p.152 apud NAVALON, 2008, p. 16). Daí a possibilidade de aproximações e distanciamentos entre as diferentes áreas do Design, pois, como bem argumenta Navalon (2008), a atividade de design pode ser comparada a construção de um tecido. É necessária a definição das interconexões estabelecidas entre o designer (trama), usuário (urdume) e o seu desejo (fio). Quando estes se entrelaçam e se interconectam, o tecido é configurado. E o segredo para tamanha variação nas áreas de atuação é que existem muitas maneiras de compor essas interconexões. (Pacheco et al., 2014, p.3)
In order to better understand the concept, the projects have been decomposed into their component parts. The drawings in Figure 5 left present the schemes of how the different volumes overlap in each project. Although the number of volumes varies, the principle of the arrangement of the composition is always the same. In these architectural compositions, the membranes (shells) can be conceived as the main constructive elements that create the structure, the skeleton. Those membranes are circular and enclose the space placed inside them. The space inside is actually empty, a void, that searches for its purpose. The purpose of the emptiness is given through its use, which is organised through the creation of another space inside it. The membranes work as a body. They limit and constrain the space, and define its gravity fields, creating a void which should have certain functions. There are many possibilities, because the void is not observed as being nothing, but rather as being something, as being the part of the architecture placed in between. Decomposition of the layers that create the composition, shown as the scheme of body and voids, helps to better understand the structural arrangements (Figure 5, right). The composition is created by mutual shifts of different bodies and voids, which create separations and at the same time transitions between spaces from the inside to the outside and vice versa.
Segundo Caldwell e Zappaterra (2014) para além do formato impresso, o mundo editorial tem, hoje em dia, uma multiplicidade de canais que podem ir dos tablets digitais às redes sociais, e tecnologias tais como o design responsivo ou o conteúdo automatizado (feeds RSS - Rich Site Summary) que têm vindo a alterar a forma como vemos texto escrito. Mas Umberto Eco (2003) garante-nos que o livro continuará indispen- sável, e que ao longo da história e da ficção já vários proclamaram o fim de algo devido a uma tecnologia nova, como a escrita acabar com a capacidade do ser humano pensar, ou o livro destruir os valores da religião, ou a televisão e outro aparelhos acabarem com o pensamento linear promovido pelos livros.
he team members are experts in perturbation theory and have contributed to the understanding of third-body perturbations, resonances in the GPS regime and they also have developed new algorithms for the eicient computation of the Lie transforms theory. he development of the goals of the project is expected to provide new results of direct application to the ields of Aerospace Engineering, Mathematics, Celestial Mechanics, and Sotware Computing. In particular, the research topic will apply to actual problems of serious concern in space community, as is the case of Space Situational Awareness. Besides, it is expected that interested students may be challenged by the diferent research lines encompassed by the project. his interest would naturally materialize in Ph.D. thesis and Master’s dissertation.
The structure of the FHP in Teresina was composed by agents who participated in the design of this space, which in the municipality were the Municipal Health Foundation (FMS), subordinate to the Municipality of Teresina body, represented by the managers of the health system, usually doctors, whose functions were to structure the operation of the field, manage the resources, hire the professional teams and arrange the service according to the guidelines of the Ministry of Health, medical teams, who performed hegemonic position in the field to be holders of scientific, economic and symbolic capital in situation of health services; teams of nurses, who brought as capital accumulated experience in the field of PACS and affinity with the work in the community, the community health workers and nurse assistants, that existed in the district health and were availed to the Family Health program and service users.
The adoption of the ARINC 653 concept in space on-board software will not only provide the space industry the same benefits the aviation industry has already profited with by adopting the standard – software portability and modularity, partitioning and less certification effort, etc. It will also promote the reusability of Research and Development (R&D) efforts already invested in the scope of another industry domain, further increase the synergies in the development of software for the parallel domains of civil aviation and space and potentiate reduction in the development costs of on-board software. Finally, the space world will benefit from ARINC 653’s improvement in the development framework available for both application developers and integrators.
Although concern about pathogens in spacecraft is certainly warranted, it should be emphasized that the ability of a pathogen to survive outside a host and the ability to infect a host are both, at least in part, dependent on the existing community of non-pathogenic microbes in those locations. For example, the infectivity of some pathogens has been shown to be very dependent on the host microbiome (e.g., Schuijt et al., 2015; Ichinohe et al., 2011; Van Rensburg et al., 2015; Reeves et al., 2011). Therefore, it is important to understand the entire microbial ecosystem of spacecraft. Indeed, in recent years, several culture-independent studies have examined the microbiome of the ISS (Castro et al., 2004; Venkateswaran et al., 2014; Moissl et al., 2007), including another part of Project MERCCURI (J Lang et al., 2015, unpublished data). These studies have shown, not surprisingly, that the microbiome of the ISS bears a strong resemblance to the microbiome of human-associated built environments on Earth. Therefore, it is of interest to see how microbes from human-associated environments behave in space.
As the site of the project is a part of an irregular mountain city of Covilhã, on every step we can see different types, forms and dimensions of deformations (See picture 20). It’s seen in different widths and curves of the streets and pedestrian paths, variety of angles meeting each other in every type of space. Even walking along each street we can see broken lines of facades and surpassing of some of them over the obvious line of the buildings. Looking up the sky we are surprised by variety of heights of the houses. Houses are full of little misalignments in facades which peoples’ brains subconsciously simplifies to a regular, repeatable systems and many others accents we don’t even understand but can sense while being the audience of these spaces. “Theory of dialogic design, and its recognition of deformation 10 being the medium of Identity” which is the main strategy for my project was introduced to me along Project IV course on UBI by Jacek Dominiczak.
Este estudo apresenta o desenvolvimento de ações em Design para valorização da produção artesanal ceramista da Comunidade Quilombola Negros do Riacho localizada no município de Currais Novos, interior do Rio Grande do Norte. A comunidade tem o artesanato de cerâmica como elemento importante da sua identidade cultural e fonte de renda complementar. Buscando a valorização da produção e dessa forma promover o desenvolvimento e continuação de marca cultural da comunidade, foram desenvolvidas duas ações em Design por meio de ferramentas de design, design e antropologia e do design etnográfico. A primeira ação teve como resultado o reconhecimento da comunidade, da produção e dos atores que a configuram. A segunda ação resultou no desenvolvimento de um artefato artesanal por meio do design, um Veículo de Tração Humana – VTH, com o objetivo de auxiliar na tarefa de extração do barro na produção artesanal da cerâmica.
The vector control performance applied to rotating machines depends largely on static and dynamic characteristics of the inverter associated with it. The development of the pulse-width modulation (PWM) provided greater flexibility in the control of the converters. The objective of this work is to construct a simplified and practical space vector modulation (SVM) based on the selection of the sequence and the calculation of the conduction time or extinction. We have presented the blocks of the simulation vector modulation on the Matlab / Simulink with a new method for determining conduction time and analyzed its application on a load RL supplied by a voltage inverter. The performance of the proposed method has been presented by the simulation results.
