Paralelização automática de laços

Identify opportunities for software parallelism is a task that takes a lot of human time, but once some code patterns for parallelism are identified, a software could quickly accomplish this task. Thus, automating this process brings many benefits such as saving time and reducing errors caused by the programmer [1]. This work aims at developing a software environment that identifies opportunities for parallelism in a source code written in C language, and generates a program with the same behavior, but with higher degree of parallelism, compatible with a graphics processor compatible with CUDA architecture.

Anomalous couplings of the third generation in rare B decays

We study the potential effects of anomalous couplings of the third generation quarks to gauge bosons in rare B decays. We focus on the constraints from flavor changing neutral current processes such as b→sγ and b →sl+l-. We consider both dimension-four and dimension-five operators and show that the latter can give large deviations from the standard model in the still unobserved dilepton modes, even after the bounds from b→sγ and precision electroweak observables are taken into account. ©2000 The American Physical Society.

Actinic Cheilitis: epidemiological study in a riverine population of northern Brazil

AIM: The aim of this survey was to assess the prevalence of AC in riverine population in countryside of Amazonas, northern Brazil. MATERIAL AND METHODS: Patients answered a questionnaire and were examined between January and December of 2008. Data were gathered on the following participant’s characteristics: 1) age group; 2) gender; 3) ethnicity 4) outdoor activities (sunlight exposure); 5) smoking habits; 6) drinking habits; and 7) access to oral health services (the last dental visit). Clinical observation of the lips for determination of AC presence was used. Patients who presented clinical manifestation of moderate and severe AC were submitted to incisional biopsy to confirm the diagnosis. In case of a positive result after histopathological examination, patients were advised and appropriate treatment was offered. All patients received information about AC and its'prevention. RESULTS: Among the 200 participants that were examined, the prevalence of AC was 2% (4 cases). Of all patients surveyed, women were the majority totalizing 124 patients (72.0%). According to age, 48 (24.0%) people were 20g34 yeargold; 42 (21.0%) were 35g44gyeargold; 50 (25.0%) were 45g60gyeargold; and 60 (30.0%) were 61 or older. CONCLUSION: Even though AC was present in a low prevalence rate, an epidemiological variety is expected, once geographic and ethnic differences should be considered.

Inspeção periódica de pulverizadores nas principais regiões de produção de soja no Brasil

The aim of this study was to evaluate the evolution of calibration and maintenance practices for crop sprayers on soybean production areas in Brazil, in the 2006 and 2007 seasons, based on the Project IPP data. Therefore, the evaluation covered issues related to calibration, maintenance condition and the main components of 103 sprayers distributed in the following states: Rio Grande do Sul (35), Paraná (60), and, Mato Grosso do Sul (8). The evaluations were done at the rate of one sprayer per farm. The most frequent problems were related to the pressure gauge, spray leaks and calibration errors greater than 50% of the desired volume rate. The analysis of the application rate showed a tendency for the farmers to apply volume rates below the desired value. In 2006 the errors of the application rate were significant, with 70.4% for Rio Grande do Sul State, 74.5% for Paraná State and 37.5% for Mato Grosso do Sul State. In 2007 there was a reduction of errors, with averages of 50.0% for Rio Grande do Sul and 66.7% for Paraná. In general terms, the results showed improvements on the use, maintenance and calibration processes for crop sprayers on the areas covered by the Project IPP, with reductions on average indexes for calibration errors, leaks and bad tips, among other issues.

Introdução aos sistemas aviônicos de rádio navegação

This work is focused on the subject of air radio navigation systems embedded on aircraft and in the ground stations. Initially is presented a historical context and motivation of the chosen theme. In the following chapters the basics avionics systems are presented, ADF, VOR, DME and ILS such that there is a deepening of electronics theory behind the operation of each system. In this graduate work were presented theories involved in systems such as the definition and creation of radio waves, the frequency spectrum used by each system, the modulation and demodulation of waves, the operating block diagrams of embedded receiver in the aircraft and the terrestrial source station, and the errors involved in the use of each system

Políticas e desenvolvimento do estado de Mato Grosso após abertura comercial: análise da visão de dois empresários atuantes no setor

After realizing two interviews, with distinct managers/businessmen working in the cotton industry, the objective is to put in evidence the political, economical and social factors that contributed to the formation and configuration of the Mato Grosso state, after the trade liberalization that occurred in the early 90's, it's effects and consequences in the eyes of the interviewed. The study of public policies is primordial to the discovery of the configuration of determined place, evaluating advances and possible errors in the social, economical and environmental areas. Through the analysis of the interviews it has been found that the urban centers have been developing with a direct link to the industrial activities related to agriculture and that the labor work force have also been attracted because of these changes, and as a consequence this labor force is now becoming more specialized to be able to accompany the jobs requirements in the industry. Analyzing the interviews, it is possible to highlight some information about the development of Mato Grosso, among those the following factors and public policies. The creation and expansion of the cities in the state are possible through public and private investment in infrastructure the socioeconomic development of the state is linked with the advances made in the private sector that grows because of advances made in crops technology in contrast to the occupation of the cerrado, in relation to the cotton crops. The problems that Mato Grosso is facing are mainly linked to the region infrastructure, that can count on investment plans to transportation and production flow that dates before the globalization era. The pattern that is seen today with top of the line agricultural production, big monoculture with high productivity and the arrival of multinational giants, was implanted because of two important events: the trade liberalization in the 1990's and the cambial depreciation in the 1999's...

A study of habitat fragmentation in Southeastern Brazil using remote sensing and geographic information systems (GIS)

The purpose of this work was to study fragmentation of forest formations (mesophytic forest, riparian woodland and savannah vegetation (cerrado)) in a 15,774-ha study area located in the Municipal District of Botucatu in Southeastern Brazil (São Paulo State). A land use and land cover map was made from a color composition of a Landsat-5 thematic mapper (TM) image. The edge effect caused by habitat fragmentation was assessed by overlaying, on a geographic information system (GIS), the land use and land cover data with the spectral ratio. The degree of habitat fragmentation was analyzed by deriving: 1. mean patch area and perimeter; 2. patch number and density; 3. perimeter-area ratio, fractal dimension (D), and shape diversity index (SI); and 4. distance between patches and dispersion index (R). In addition, the following relationships were modeled: 1. distribution of natural vegetation patch sizes; 2. perimeter-area relationship and the number and area of natural vegetation patches; 3. edge effect caused by habitat fragmentation, the values of R indicated that savannah patches (R = 0.86) were aggregated while patches of natural vegetation as a whole (R = 1.02) were randomly dispersed in the landscape. There was a high frequency of small patches in the landscape whereas large patches were rare. In the perimeter-area relationship, there was no sign of scale distinction in the patch shapes, In the patch number-landscape area relationship, D, though apparently scale-dependent, tends to be constant as area increases. This phenomenon was correlated with the tendency to reach a constant density as the working scale was increased, on the edge effect analysis, the edge-center distance was properly estimated by a model in which the edge-center distance was considered a function of the to;al patch area and the SI.
