13. Avaliação dos requisitos para teste de um sistema operacional embarcado / Testing requirements for an embedded operating system
A sociedade está cada vez mais dependente de sistemas embarcados, sendo que na grande maioria das vezes eles operam de maneira invisível aos seus usuários. Essa dependência torna esses usuários vulneráveis a riscos, devido às falhas que podem ocorrer. Essas falhas podem provocar perdas de vidas ou sérios danos materiais e financeiros. Devido a estes

14. 3D routing with context awareness
The emergence of low-cost, wireless network interfaces in the market and the ever increasing growth in demand of mobile devices (such as SmartPhones, PDAs, Internet Tablets and Laptops) enabled scenarios where network services for mobile users may exist in an ad hoc fashion, with no pre-existing communications infrastructure. However, the creation of such dy

15. Evaluation of the effect of the bleaching agent and the subsequent application of sodium fluoride on intra-coronal dentine microhardness / Avaliação do efeito do agente clareador e da subseqüente aplicação de fluoreto de sódio na microdureza da dentina intracoronária
The aim of the present study was to evaluate the microhardness of intra-coronal dentine submitted to bleaching with 38% hydrogen peroxide, photo-activated with LED-Laser and followed by the application of 2% sodium fluoride gel or 5% varnish. Crowns of 45 human maxillary canines were sectioned in the buccal-lingual direction and a sample of 25 mm of internal

16. Internal adaptation of cast titanium crowns
As the adaptation of titanium crowns obtained by Rematitan Plus investment, specific for titanium, is not recognized to be suitable, this study evaluated the effect of the concentration of the specific liquid and the temperature of the mold of investments on the internal misfit of crowns cast on commercially pure titanium. Individual dies of epoxy resin were

18. A platform development framework and a debugging mechanism based on computacional reflection / Um framework de desenvolvimento de plataformas e um mecanismo de depuração baseado em reflexão computacional
Digital systems are becoming more and more complex through the years, putting general purpose processors together with specialized hardware and buses into the same silicon die, due to power, area and performance constraints. In order to deal with this complexity and a short time-to-market, designers are adopting high level hardware descriptions, based on lan

19. Comparative study of the adaptation between metallic copings and alumina, in system In-Ceram, before and after cementation / Estudo comparativo da adaptação entre copings metalicos e de alumina, no sistema In-Ceram, antes e apos cimentação
The purpose of this study was to evaluate the marginal fit before and after cementation of metal and aluminium oxide In-Ceram copings, on bovine teeth preparation using two kinds of cement. Sixty bovine incisors were embedded in resin and the coronal portions of the teeth were prepared to receive complete crowns usin a 4103 diamond bur under refrigeration wi

20. Shear bond strenght of porcelain repairs etched with laser / Resistência adesiva ao cisalhamento de reparos em porcelana condicionada com laser
The aim of this study was to evaluate in vitro the shear bond strength of repairs in porcelain conditioned with laser and to compare it to the traditional repair methods conditioned with hydrofluoric acid and phosphoric acid. In this study, were used two conditioning porcelain (10% hydrofluoric acid - Dentsply; 37% phosphoric acid - 3M ESPE), a silane agent

21. Geração de especificações executáveis para o projeto de módulos para sistemas em "Chips"
The increasing demand for electronic components is driving the integrated circuit market to an unexpected growth. In the about two to four years it will be possible to find circuits composed of a billion transistors. This capacity of integration is the responsible for the emergence of a new concept, System-on-a-chip (SoC), in which a complete computational s

22. Modelagem e simulação de barramentos com systemC / Modeling and simulation of bus using SystemC
The system-on-chip era is creating new challenges to the system design. There is an increasing demand for smaller electronic devices with more features and reduced time to market. To face these new challenges is necessary to introduce new methodologies and development techniques. Buses are important elements for connecting devices in a complex system. To inc

23. RESISTÊNCIA À TRAÇÃO DE UM SISTEMA DE ANCORAGEM EMBUTIDO EM CONCRETO SUJEITO A CARGA DE IMPACTO / TENSILE STRENGTH OF A CONCRETE ANCHORING SUBJECTED TO IMPACT LOAD
This work investigates the strength of a concrete anchor system constituted of headed studs embedded in concrete subjected to impact tension load. The main variable was the loading rate which varied from a minimum of 0,015 kN/s (static) to a maximum of 54885 kN/s. The anchor system was designed so that the failure was governed by concrete cone breakout. Elev

24. Stereological and morphometric analysis of collagen and seminiferous tubules in testes of patients with cryptorchidism submitted or not to treatment with human chorionic gonadotrophin
OBJECTIVES: Quantify the distribution of collagen and analyze the seminiferous tubules diameter in the testis of patients with cryptorchidism, to verify if the previous use of human chorionic gonadotrophin (hCG) affects these structures. MATERIALS AND METHODS: Samples of parenchymal tissue of cryptorchid testis obtained during peroperative biopsies were coll
