13. Um modelo de memória transacional para arquiteturas heterogêneas baseado em software Cache / A transactional memory model for heterogeneous architectures based in Software Cache
The adoption of multi-core processors by the industry has pushed towards the development of new techniques to simplify programming parallel software. The technique called transactional memories is one of the most promising. This technique is able to execute multiple tasks concurrently in an optimistic way to achieve a better performance. Another advantage is

14. Acesso paralelo a arquivos em sistemas multiprocessadores. / Parallel access to files for multiprocessor systems.
This work presents a study on disk access bottlenecks for multiprocessor architecture systems and also proposes a specification to solve this problem and its implementation. The developed strategy is called FPA. The developed strategy makes use of shared memory architecture and uses shared data buffers among several application threads and also tries to opti

15. Photographhic Palimpsests. Images, reminiscences and identifications in memory narratives by elderly. Londrina, Paraná state of Brazil, 2006-2008 / Palimpsestos fotográficos : imagens, lembranças e identificações em narrativas de memória por pessoas idosas. Londrina, Paraná, 2006-2008
This work researches elderly memory narratives, composed by relationships involving personal photographs and reminds. Starting from a cultural project experience, developed between the years of 2007 and 2008, at Londrina, Paraná state, where each person built a memories álbum collecting photos, handwrites and hand skills in order to arrange an artistic nar

16. Resolução de um problema térmico inverso utilizando processamento paralelo em arquiteturas de memória compartilhada / Resolution of an inverse thermal problem using parallel processing on shared memory architectures
A programação paralela tem sido freqüentemente adotada para o desenvolvimento de aplicações que demandam alto desempenho computacional. Com o advento das arquiteturas multi-cores e a existência de diversos níveis de paralelismo é importante definir estratégias de programação paralela que tirem proveito desse poder de processamento nessas arquitetu

17. Production and maintenance of a teacher s collective : a teacher training experience within the professional realm / Produção e sustentação de um coletivo docente : uma experiencia de formação de professores dentro do universo profissional
This study analyses the working process of a teacher s collective around a science fair curricular project within a São Paulo school. This science fair has been held annually since the school s inauguration in 1994. Our main objectives have been to identify elements that contribute to the maintenance of this teacher s collective work and to analyze the prof

18. O ensino de literatura na educação profissional agrícola numa perspectiva dialógica: formando leitores. 2010. / Teaching literature for technical courses in agricultural education from a dialogical perspective: training readers. 2010.
The present work aimed to study the process of understanding literary texts and the construction of concepts in literature, from a teaching and learning experience focused on dialogical interactions, within the classroom. We also intended to provide subsidies to improve the teaching of literature. Based on the premise that the teaching of this discipline, in

19. Explorando memoria transacional em software nos contextos de arquiteturas assimetricas, jogos computacionais e consumo de energia / Exploiting software transactional memory in the context of asymmetric architectures
The shift towards multicore processors taken by the semiconductor industry has initiated an era in which new languages, methodologies and tools are of paramount importance to the development of efficient concurrent systems that can be built in a timely way by all kinds of programmers. One of the main obstacles faced by programmers when dealing with shared me

20. Teste de programas concorrentes com memória compartilhada / Test of shared memory concurrent programs
This work presents a novel test model for shared memory concurrent programs. Some important new features in this model are: (1) analysis the communication and synchronization in an isolated manner, (2) examines the synchronization due the start and the finish of threads, and (3) employs a method based on timestamps to check the communication exercised for an

21. História com Dona Prizulina da beira do fogão à cultura visual / History DonaPrizulina with the edge of the stove to the visual culture
As a storytelling, this work aims at delineate new glances and senses about my own academic path and about how it is linked with other experiences shared on the imaginary that moves the daily life of my hometown. Base on the principles of autoethnography, I seek to comprehend and to rebuild part of a visual network in which some narratives gathered in Lagol�

22. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial

23. O endosso por celebridade e a gestão da imagem da marca : evidências empíricas a partir do estudo da marca Ipanema Gisele Bündchen
Positioning is a fundamental concept to understand the role played by brands in contemporary societies, which applies to what the brand represents on consumers minds. On that account, the archetype paradigm is an approach that has, in recent years, aroused interest of some marketing experts, suggesting the existence of a collective unconscious, part of the p

24. Avaliação do compartilhamento das memórias cache no desempenho de arquiteturas multi-core / Performance evaluation of shared cache memory for multi-core architectures
No atual contexto de inovações em multi-core, em que as novas tecnologias de integração estão fornecendo um número crescente de transistores por chip, o estudo de técnicas de aumento de vazão de dados é de suma importância para os atuais e futuros processadores multi-core e many-core. Com a contínua demanda por desempenho computacional, as memóri
