14. A transparent and energy aware reconfigurable multiprocessor platform for efficient ILP and TLP exploitation
As the number of embedded applications is increasing, the current strategy of several companies is to launch a new platform within short periods, to execute the application set more efficiently, with low energy consumption. However, for each new platform deployment, new tool chains must come along, with additional libraries, debuggers and compilers. This str

15. Caracterização de resíduos sólidos da construção civil para sua utilização em camadas drenantes de aterros sanitários / Characterization of construction waste for use as drainage materials in sanitary landfills
Intense population growth brings with it environmental concerns, since exploitation of natural resources, makes it essential to adopt recycling policies in order to achieve sustainable development. Therefore, this study sought to define a new application for recylcling construction and demolition waste (CDW-R). Two size distributions that could be readily pr

16. Caracterização de três seringais manejados em terra firme, várzea e terra preta de índio no médio Amazonas
Seeking technical information to subsidize strategies to develop heveaculture in the Amazon state, a team of researchers of the National Institute of Amazon Research started in 2008 a descriptive research in rubber plantations in the Middle Amazon region, located in floodplain, in terra firme (TF) and indian black earth (TPI). In these areas we did: phytosoc

17. Proposta de interconexão do padrão ISO 11783 com redes de sensores sem fio padrão ZigBee. / A proposal for interconnection between ISO 11783 standard network and ZigBee wireless sensor networks.
Precision Agriculture is one of the technological advances used to recoup the treatment of spatial and temporal variability in agricultural crops. Besides other benefits, it tries to improve the exploitation of applied inputs, improve the productivity and reduce production cost as well as lessen the impact on environment caused by excess of input. To achieve

18. LALP: a language for parallelism of loops exploitation in reconfigurable computing / LALP: uma linguagem para exploração do paralelismo de loops em computação reconfigurável
Reconfigurable computing is becoming increasingly important in embedded and high-performance computing systems. It allows performance levels close to the ones obtained with Application-Specific Integrated circuits (ASIC), while still keeping design and implementation flexibility. However, to efficiently program devices, one needs the expertise of hardware de

19. Active magnetic bearing applied to a tubular linear induction motor. / Mancal magnético ativo aplicado a um motor de indução linear tubular.
A tubular linear induction motor applied to onshore oil exploitation, named MATÆOS (which is in the Portuguese acronym for Tubular Asynchronous Motor for Onshore Oil Exploitation) was built at Escola Politécnica da Universidade de São Paulo (EPUSP). Its purpose is to directly drive the sucker-rod pump installed in the down hole of the oil well. In continu

20. Analysis on the limitation of the law in the solution of environmental conflicts: the use of geographic information systems in judicial proceedings / Análise das limitações do direito na solução de conflitos ambientais: a aplicação de sistemas de informações geográficas a processos judiciais
There is a hiatus between the environmental law existence, mainly because of its great rigidity, and the fact of being considered an impediment to the economic development. The Permanent Preservation Areas (PPA) and Legal Forest Reserve (LFR) are institutes created by the Environmental Law that limit the economic exploitation in rural properties without an i

21. Identificação dos sistemas de produção agropecuária do arenito caiuá sujeitos a erosão utilizando o modelo AGNPS
The series of impacts due to the inadequate exploitation of natural resources by agriculture produces, among other effects, the erosion of the soils, which causes serious damage to the society through the reduction of its productive capacity and the continuous contamination of surface water with sediments, material and organic matter, chemical products and n

22. Partição da extração da água do solo por plantas entre camadas com teores de água distintos / Partition of root water extraction between soil layers with distinct water contents
Water shortage is one of the most limiting factors for agricultural production. The understanding of factors that rule the extraction of soil water by plants and its distribution along the root system under contrasting hydraulic conditions is important for fine-tuning hydrological models which are a reference for crop growth models, meteorological models, am

23. Utilização de taro na elaboração de farinha e de produto alimentício reestruturado frito / Use of taro in the preparation of flour and fried restructured food products
The aim of this work was to use taro [Colocasia esculenta (L.) Schott] corm (RM) and cormels (RF) to produce restructured fried foods, with emphasis on the potential of RM for industrial use. Chemical composition, instrumental and sensory analysis were used to characterize raw materials (taro rhizomes) and its products (flour and restructured food). RM provi

24. The influence of variable operating conditions on the design and exploitation of fly ash pneumatic transport systems in thermal power plants
The efficiency of an air-slide pneumatic conveying system depends, first of all, on several basic elements chosen or calculated during the design of a plant: air-slide design parameters, air mover characteristics, as well as the physical and chemical properties of the material to be transported. However, during the exploitation of this type of system which i
