Reuse-based test planning for core-based systems-on-chip

Electronic applications are currently developed under the reuse-based paradigm. This design methodology presents several advantages for the reduction of the design complexity, but brings new challenges for the test of the final circuit. The access to embedded cores, the integration of several test methods, and the optimization of the several cost factors are just a few of the several problems that need to be tackled during test planning. Within this context, this thesis proposes two test planning approaches that aim at reducing the test costs of a core-based system by means of hardware reuse and integration of the test planning into the design flow. The first approach considers systems whose cores are connected directly or through a functional bus. The test planning method consists of a comprehensive model that includes the definition of a multi-mode access mechanism inside the chip and a search algorithm for the exploration of the design space. The access mechanism model considers the reuse of functional connections as well as partial test buses, cores transparency, and other bypass modes. The test schedule is defined in conjunction with the access mechanism so that good trade-offs among the costs of pins, area, and test time can be sought. Furthermore, system power constraints are also considered. This expansion of concerns makes it possible an efficient, yet fine-grained search, in the huge design space of a reuse-based environment. Experimental results clearly show the variety of trade-offs that can be explored using the proposed model, and its effectiveness on optimizing the system test plan. Networks-on-chip are likely to become the main communication platform of systemson- chip. Thus, the second approach presented in this work proposes the reuse of the on-chip network for the test of the cores embedded into the systems that use this communication platform. A power-aware test scheduling algorithm aiming at exploiting the network characteristics to minimize the system test time is presented. The reuse strategy is evaluated considering a number of system configurations, such as different positions of the cores in the network, power consumption constraints and number of interfaces with the tester. Experimental results show that the parallelization capability of the network can be exploited to reduce the system test time, whereas area and pin overhead are strongly minimized. In this manuscript, the main problems of the test of core-based systems are firstly identified and the current solutions are discussed. The problems being tackled by this thesis are then listed and the test planning approaches are detailed. Both test planning techniques are validated for the recently released ITC’02 SoC Test Benchmarks, and further compared to other test planning methods of the literature. This comparison confirms the efficiency of the proposed methods.

Transformação tecnológica e estratégia competitiva: um estudo multicaso

O objetivo principal desta pesquisa é investigar como a inovação tecnológica ajuda a moldar estratégias, para obtenção de vantagens competitivas sustentáveis, em um contexto de globalização. Com base em extensa revisão bibliográfica, compreendendo competitividade, tecnologia, estratégia e alianças estratégicas é explorado o fenômeno da inovação tecnológica e sua inserção na gestão estratégica de quatro empresas dos setores de celulose, siderurgia, químico-farmacêutico e de aplicações médicas da energia nuclear. Inicialmente, o conceito de competitividade e a estrutura industrial brasileira são analisados a luz de três modelos distintos. Também é realizada uma avaliação do conceito de competências essenciais das organizações e arquiteturas estratégicas. Posteriormente é avaliada a relação entre vantagem competitiva e inovação tecnológica e as dimensões estratégicas da tecnologia. Finalmente são descritas as escolas de pensamento estratégico e as relações entre alianças estratégicas e transferência de tecnologia. São analisadas as características estruturais e competitivas de cada um dos setores estudados, bem como apresentados perfis das empresas representantes de cada setor. Os dados de cada uma das empresas foram obtidos por meio de entrevistas semi-estruturadas. Os resultados são analisados individualmente e posteriormente consolidados. Os resultados do estudo permitiram identificar que a variável tecnológica é inserida na gestão estratégica das empresas em três níveis distintos. O primeiro nível é o de análise; o segundo é o de decisões estratégicas e finalmente o terceiro nível é o de implementação estratégica. Também foram identificadas as fontes de tecnologia normalmente utilizadas pelas organizações objeto do estudo. Por fim, é sugerido que o modelo de estrutura industrial de Porter pode receber contribuições no sentido de incorporar as estratégias cooperativas das empresas por meio de indicadores de cooperatividade.

Análise do processo de implantação do balanced scorecard: o caso do painel corporativo de uma empresa brasileira do setor público

Um assunto cada vez mais recorrente na literatura sobre administração é a questão dos modismos de gestão. Nos anos 90 se observou a euforia em torno da gestão pela qualidade total (TQM) e a explosão da reengenharia de processos, que veio junto com a terceirização. Em seguida emergiu o conceito de core-competencies ou competências essências que deu origem à revolução da gestão baseada em competências. Surgido nos anos 90, a partir de pesquisas acadêmicas, o Balanced Scorecard (BSC) aparece como uma nova tecnologia de gestão que rapidamente foi difundida e passou a ser utilizada por uma extensa gama de organizações. A recente utilização dessa tecnologia de gestão e o excesso de euforia sobre o tema trazem a tona o questionamento sobre a correta utilização da mesma. Sendo assim, essa pesquisa se dedica a fazer uma análise sobre a utilização do BSC em uma empresa brasileira do setor público frente à metodologia proposta pela literatura. Os resultados da pesquisa demonstraram que os motivos que levaram a empresa em questão a escolher o BSC como tecnologia de gestão e a construção do BSC foram coerentes com a metodologia proposta pela literatura. Por fim a pesquisa também revelou dois resultados inesperados: primeiro um possível fator de sucesso na utilização do BSC não encontrado na literatura; e segundo uma certa peculiaridade quanto a adoção dessa tecnologia de gestão em empresas do setor público.

Tapping into your people: successfully managing idea generation in organisations

Over the past few years, innovation has increasingly garnered the headlines as one of the core competencies every sustainable organisation must have. Yet, it is the idea which is the foundation of any innovation. This paper draws together knowledge about idea generation, and its management, and how the process of encouraging ideas, creativity and then managing them effectively will enhance the opportunities of successfully finding and implementing innovations which will add value to the organisation and its stakeholders. Extensive review of literature in the field of idea and innovation management, as well as a study of Souza Cruz¿s recently conceptualised and implemented Idea Management programme has brought together the many facets involved in successfully harnessing and implementing ideas.

As competências essenciais dos profissionais em vendas de bens perecíveis: um modelo genérico de competências

Esta tese estuda as competências essenciais requeridas dos profissionais em vendas de bens perecíveis diante das mudanças ambientais e novas estratégias de relacionamento entre as indústrias de alimentação e seus canais de marketing. Há revisões teóricas sobre marketing e venda pessoal no lado da Administração e sobre competências no lado da Psicologia. Da revisão teórica foram selecionadas 16 competências chave para compor um dicionário, convenientes ao atual contexto de relacionamento entre comprador e vendedor. A pesquisa foi conduzida entre participantes de comitês do Movimento ECR Brasil, funcionários de supermercados e de indústrias de alimentação (n = 192). Empregaram-se as técnicas estatísticas da análise fatorial exploratória e da análise fatorial confirmatória e o modelo teórico foi gerado com três dimensões - suporte à competitividade, relacionamento eficaz e integração operacional - abrangendo 12 competências essenciais. Foram testadas as validades convergente, discriminante e nomológica dos constructos do modelo teórico. Quanto às medidas de ajustamento global do modelo teórico mais o índice esperado de validação cruzada (ECVI) foi possível constatar que o modelo demonstrou consistência com os dados e teve uma boa aproximação da população (X² = 68,15, DF = 51, p = 0,054, RMSEA = 0,042). A avaliação dos resultados do modelo de medidas revelou evidência parcial quanto à validade dos constructos e baixa fidedignidade quanto aos indicadores do modelo teórico.

Non-emptiness of the alpha-core

We prove non-emptiness of the alpha-core for balanced games with non-ordered preferences, extending and generalizing in several aspects the results of Scarf (1971), Border (1984), Florenzano (1989), Yannelis (1991) and Kajii (1992). In particular we answer an open question in Kajii (1992) regarding the applicability of the non-emptiness results to models with infinite dimensional strategy spaces. We provide two models with Knightian and voting preferences for which the results of Scarf (1971) and Kajii (1992) cannot be applied while our non-emptiness result applies.

A representação social do CIO no Brasil na percepção dos profissionais de tecnologia da informação

O papel da Tecnologia da Informação (TI) no dia-a-dia das organizações torna-se cada vez mais importante e, consequentemente, o papel de seus profissionais. O presente trabalho tem como objetivo principal investigar a percepção dos profissionais de TI brasileiros acerca das competências essenciais que o principal executivo de TI (Chief Information Officer - CIO, em Inglês) atuante no mercado brasileiro deve ter para desempenhar adequadamente suas funções. O levantamento dessa percepção foi feito tendo por base a Teoria das Representações Sociais, por meio do método de evocação de palavras. Por intermédio da análise das percepções, foi possível identificar as competências e compará-las àquelas identificadas na literatura científica.

Measuring core inflation as the common trend of prices

In recent years, many central banks have adopted inflation targeting policies starting an intense debate about which measure of inflation to adopt. The literature on core inflation has tried to develop indicators of inflation which would respond only to "significant" changes in inflation. This paper defines a measure of core inflation as the common trend of prices in a multivariate dynamic model, that has, by construction, three properties: it filters idiosyncratic and transitory macro noises, and it leads the future leveI of headline inflation. We also show that the popular trimmed mean estimator of core inflation could be regarded as a proxy for the ideal GLS estimator for heteroskedastic data. We employ an asymmetric trimmed mean estimator to take account of possible skewness of the distribution, and we obtain an unconditional measure of core inflation.

Relationship of Coca-Cola Brazil and the communities participant of the social projects: (im) possibilities

Five years ago, Coca-Cola Brasil launched a program named “Coletivo Project”, with the purpose to enjoy an opportunity of increase on the potential consumption power of the low-income pyramid population that lived on the “favelas”. At the same time, it had the objective to offer to them a social and financial impact, which is a trust on the future, the first job for the young adults’ participant of this program and an increase on their family source of revenues, through salaries. This was possible because through Coletivo Project, Coca-Cola identified the assets they have through its value chain, focusing on its competencies, such as retail, merchandising and logistics to apply them on courses to teach the young people of the communities and, as a result, form them to be able to find their new jobs. Internal indicators followed in a monthly basis by Coca-Cola demonstrated that the communities that had the presence of Coletivos, in comparison to those without Coletivos, had social and financial impacts. The social was the fact that the young formed started to have more confidence on their future and felt with a higher self-stem to apply for and obtain their first job. On the financial aspect, they were benefit through the increasing of their revenues and also their families and Coca-Cola had an increase on sales, when compared to a community without a Coletivo Project installed. This dissertation seeks to identify the current relationship between Coca-Cola and the communities, through the Coletivo Project classes performed on the NGOs located at this places, in order to identify opportunities for improvement the benefits and the impacts (financial and social) on the NGOs, communities and all stakeholders of this project. This dissertation examines this relationship, through presence interviews performed on four NGOs selected, and located on four of the twenty communities, that are participants of the Coletivo Project on Rio de Janeiro city. These interviews performed with the students, representatives and educators of these NGOs. The covered period of the interviews ranges from April 2014 to August 2014. This dissertation draws on first-hand qualitative empirical evidence gathered through extensive fieldwork. The main findings among possibilities for improvement by Coca-Cola are: • Implement new courses, beyond those existent at Coca-Cola (Retail, Logistics, etc.). • Increase the content of the employment module of Coletivo classes, focusing on improving educational, cultural, economic, political, social and professional life. • Increase the scale, through the quantity of positions on the Retail Coletivo classes. • Develop cultural and sports events with the communities. • Support the points of sales, participant of the practical classes of the Coletivo Retail, with refrigerators and furniture with the Coca-Cola logo. • Provide coffee breaks and meals during the Coletivo classes, using Coca-Cola beverages and partners for food items, developing the nutrition platform of the company and filling a need of the students. • Perform a research with all stakeholders related to this Project, including those students and mothers that are not participant of the Coletivo, in order to listen to them, understand their needs, and offer solutions to fulfill these gaps. and on the side of the • Perform partnerships with educational institutions to make viable other type of courses, more technical, but that have a relation with the core business of Coca-Cola Brasil, such as marketing. • Implement the Coca-Cola University, already existed at the Company. • Create courses or activities focused on the children. Regarding the impossibilities, the findings are: • Improve the basic sanitation of the communities. • Improve the safety on the communities. • Provide a home to those do not have. • Implement courses that have no relationship with Coca-Cola business and expertise, such as gastronomy. However, Coca-Cola can influence stakeholders on that. The results suggest to executives of Coca-Cola that a deep and a qualitative research on the communities of Brazil, in order to listen young people, educators, mothers, partners that offer jobs, from Coletivo and out of the project, is mandatory, to understand their needs, dreams, complains and offer valuable solutions to all.

What makes a humanitarian supply chain resilient? The relevance of the capabilities for resilience within humanitarian supply chain and their identification within the typhoon Yolanda

Centenas de milhões de pessoas são afetadas por desastres a cada ano. Para alguns países da Ásia, os desastres naturais se tornaram algo comum para os quais eles precisam estar preparados. A cadeia de fornecedores humanitária é um conceito logístico recente, que se refere a todo o processo de ajuda que acontece uma vez que ocorre um desastre, desde os doadores até os beneficiários finais. Por causa de tensões econômicas recentes, e por causa de uma maior cobertura da mídia sobre os desastres naturais mortais tal como o Typhoon Yolanda em 2013-2014; organizações humanitárias precisam mostrar transparência em suas ações e precisam provar a capacidade de resistência da cadeia de abastecimento para melhorar ainda mais os programas de doação. Resiliência tem sido estudada no contexto da cadeia de fornecedores de uma empresa comercial. No entanto olhar para essa noção dentro do sector humanitário que tem características diferentes, é um novo conceito raramente explorado antes. O objetivo desta tese será contribuir com novos insights e contributos, a fim de enriquecer ainda mais pesquisas sobre a capacidade de resiliência das cadeias de fornecedores humanitários. Vamos analisar as provas desses recursos para a resiliência através de uma pesquisa qualitativa sobre o caso Typhoon Haiyan (Yolanda), que já foi o tufão mais mortal das Filipinas.

Metodologia para adaptação de microarquiteturas microprogramadas soft-core à uma ISA padrão: estudo do impacto sobre a complexidade de hardware para o padrão MIPS

In academia, it is common to create didactic processors, facing practical disciplines in the area of Hardware Computer and can be used as subjects in software platforms, operating systems and compilers. Often, these processors are described without ISA standard, which requires the creation of compilers and other basic software to provide the hardware / software interface and hinder their integration with other processors and devices. Using reconfigurable devices described in a HDL language allows the creation or modification of any microarchitecture component, leading to alteration of the functional units of data path processor as well as the state machine that implements the control unit even as new needs arise. In particular, processors RISP enable modification of machine instructions, allowing entering or modifying instructions, and may even adapt to a new architecture. This work, as the object of study addressing educational soft-core processors described in VHDL, from a proposed methodology and its application on two processors with different complexity levels, shows that it s possible to tailor processors for a standard ISA without causing an increase in the level hardware complexity, ie without significant increase in chip area, while its level of performance in the application execution remains unchanged or is enhanced. The implementations also allow us to say that besides being possible to replace the architecture of a processor without changing its organization, RISP processor can switch between different instruction sets, which can be expanded to toggle between different ISAs, allowing a single processor become adaptive hybrid architecture, which can be used in embedded systems and heterogeneous multiprocessor environments

Antibodies to yeast Sm motif 1 cross-react with human Sm core polypeptides

Two regions common to all UsnRNP core polypeptides have been described: Sm motif 1 and Sm motif 2. Rabbits were immunized with a 22 amino-acid peptide containing one segment of Sm motif 1 (YRGTLVSTDNYFNLQL-NEAEEF, corresponding to residues 11-32) from yeast F protein. After immunization, the rabbit sera contained antibodies that not only reacted specifically with the peptide from yeast F protein but also cross-reacted with Sm polypeptides from mammals; that is, with purified human U1snRNPs. The results suggest that the peptide used and human Sm polypeptides contain a common feature recognized by the polyclonal antibodies. A large collection of human systemic lupus erythematosus sera was assayed using the yeast peptide as an antigen source. Seventy per cent of systemic lupus erythematosus sera contain an antibody specificity that cross-reacts with the yeast peptide.
