LALPC: uma ferramenta para compilação de programas em C para exploração do paralelismo de loops em FPGAs
(Universidade Federal de São Carlos, 2015-02-04) Porto, Lucas Faria; Menotti, Ricardo; https://lattes.cnpq.br/2509766431540422; https://lattes.cnpq.br/2383360392057247
The physical limitations of silicon forced the industry to develop solutions that exploit the processing power of combining several general purpose processors. Even complex supercomputers that have multiple processors, they are still considered to inefficient processes that require large amounts of arithmetic operations using floating point data. Reconfigurable computing is gaining more space to have a performance close to a specific purpose devices (ASIC), and yet keep the flexibility provided by the architecture of general purpose processors. However, the complexity of hardware description languages often becomes a problem to the development of new projects. Tools for high-level synthesis have become more popular, they allow the transformation code in high-level hardware simply and quickly. However, solutions found in current tools generate simple hardware that does not exploit the techniques to improve the pipeline in hardware. This paper presents the development of techniques to exploit processing parallelism of the reconfigurable devices through programs described in language C. These techniques identify loops and improve the performance in hardware. As a result, we have improved in the high-level synthesis process generating optimized hardware.
Comportamento reprodutivo do tangará-dançarino, Chiroxiphia Caudata (aves Pipridae) em uma área de Mata Atlântica

The family Pipridae is endemic to the Neotropics, having frugivorous habits. Males of some species make complex sexual displays to attract the females, and they live in the middle stratum of tropical forests. Of 51 species, 29 have their nests described, five have incubation periods descriptions, and six have nestling periods reported. The Blue Manakin, Chiroxiphia caudata, is common in humid and secondary forests of southeastern Brazil, northeastern Argentina and eastern Paraguay and its breeding biology is poorly documented. Here analyzed 36 active nests in two breeding seasons (2013/2014 and 2014/2015) in a well-preserved Brazilian Atlantic Forest continuum. Nests were swallow cups hung by their rims in horizontal forks, built in bushes or saplings, over or near forest streams. Reproductive activities were recorded from October to February and clutch sizes were invariably two eggs. Incubation period was 18 days, and nestling period was 15 - 16 days. Estimated overall nesting success, from egg-laying to fledging, was 40%, being higher than most studies on piprids that have been conducted in disturbed habitats. Our data give support to the theory that in the Pipridae family only females provide parental care.
O impacto do processo de financeirização sobre a estrutura social nas empresas: estudo de caso no setor elétrico paulista
(Universidade Federal de São Carlos, 2015-02-04) Matsuda, Patricia Mari; Donadone, Julio César; https://lattes.cnpq.br/7643906508178259; https://lattes.cnpq.br/9302285145256743
With the process of financialization of the economy, companies are reorganizing themselves. In front of this, the present work has as main objective observe the process of financialization and its impact on the social structure of a company that went through the privatization process. Also, analyze in the corporate environment, (the new) forms of organizational management and production, as well its key actors and their forms of interrelationship. This work is based on Political Economics, with studies in the financialization process rooted in culture, history and policy of a company that has undergone in a series of transformations. This research develops how the company changes its conception of control, and how this change has an impact in its overall structure. Thus, the scope of this work focused on an exploratory study in Eletropaulo. The central importance of the study in the Brazilian electric sector is that this sector has undergone to the most radical changes in the financialization since 1990. However, any research on the built of the executive s careers, in this Brazilian context, has been done so far. The analysis of curriculum is the most important contribution from this case study research. As a research procedure of this work, were combined quantitative and qualitative methods. In order to analyze the careers of executives of AES Eletropaulo, were collected the curriculum of the Board and Directors, since its appearance as state-owned company in 1979 to the year 2012. It is applied a cumulative frequency analysis and other correspondence multiple analysis to study these curricula. Also, to see how the company was restructured as a whole after the change of ownership, were used other qualitative tools, such as questionnaires and interviews to key players in the buying and selling process. To develop this thesis, the case study will be separated into three parts. In the first are analyzed and presented data, in the form of graphs, related to the performance indicators of the company's case over his years before and after privatization. The second part is related to the new organizational management, which refers to the shareholding after the sale of the company, thus, opens up the discussion to the internationalization of ownership and National Development Bank in Brazil - BNDES, being the major shareholders of AES Eletropaulo an international company and BNDES. And in the third, the focus is on the analysis of the careers of executives of this company, and how they constructed and reconstructed their careers after major changes. As result, it was observed that the case company has undergone a series of transformations, including the creation of a new identity. The Government acts in two different moments at the same company. It is observed in this study that the pressure of these new owners have consequences in organizational design and composition of the power of the company to a search for maximization of the value of the company. And the executives of the company had to find ways to rebuild their careers in accordance with the new financial logic at the moment. The present analysis also extends to the electricity utility workers and their vulnerabilities occurred by the financialization process.
