2. Automatic calibration of a large-scale sediment model using suspended sediment concentration, water quality, and remote sensing data
RESUMO A calibração e a validação são duas etapas importantes na aplicação de modelos de sedimentos que requerem dados observados. Nesse contexto, este estudo investigou o potencial de uso dos dados de concentração de sedimentos em suspensão (CSS), qualidade da água e sensoriamento remoto na calibração e validação de um modelo hidrossedimentol

3. Effects of remote ischemic preconditioning and topical hypothermia in renal ischemia-reperfusion injury in rats
Abstract Purpose: To evaluate whether combining hypothermia and remote ischemic preconditioning (RIPC) results in protection from ischemia-reperfusion (IR). Methods: Thirty-two Wistar rats underwent right nephrectomy and were randomly assigned to four experimental protocols on the left kidney: warm ischemia (group 1), cold ischemia (group 2), RIPC followed

4. Efficient medical image access in diagnostic environments with limited resources
Abstract Introduction A medical application running outside the workstation environment has to deal with several constraints, such as reduced available memory and low network bandwidth. The aim of this paper is to present an approach to optimize the data flow for fast image transfer and visualization on mobile devices and remote stationary devices. Methods

5. São Paulo urban heat islands have a higher incidence of dengue than other urban areas
Urban heat islands are characterized by high land surface temperature, low humidity, and poor vegetation, and considered to favor the transmission of the mosquito-borne dengue fever that is transmitted by the Aedes aegypti mosquito. We analyzed the recorded dengue incidence in Sao Paulo city, Brazil, in 2010-2011, in terms of multiple environmental and socio

7. Architecture of a remote impedance-based structural health monitoring system for aircraft applications
The essence of structural health monitoring (SHM) is to develop systems based on nondestructive inspection (NDI) technologies for continuous monitoring, inspection and detection of structural damages. A new architecture of a remote SHM system based on Electromechanical Impedance (EMI) measures is described in the present contribution. The proposed environmen

8. Neuro estimador para o fluxo de gases entre a superfície terrestre e a atmosfera / A neuro estimator for the flux of gases between the surface land and the atmosphere
Studies show that global warming may be irreversible in the medium or long term, and is a major cause of air pollution. However, this framework can be reversed or mitigated by estimating the amount of emissions, since the mapping of pollution sources could facilitate the work of public authorities in relation to environmental monitoring and the development o

9. BUILDING 3D DETECTION AND EXTRACTION IN INFORMAL SETTLEMENT AREAS / DETECÇÃO E EXTRAÇÃO 3D DE EDIFICAÇÕES EM ÁREAS DE ASSENTAMENTOS INFORMAIS
Informal settlements in many Brazilian urban centers are growing up quickly. Remote Sensing techniques provide a cost-effective mean to measure such an expansion. In cities with rough topography, like the city of Rio de Janeiro, the initial expansion, predominantly horizontal, is gradually being shifted to vertical, as new floors are being built on the exist

10. Integrating mixed-reality remote experiments into virtual learning environments using interchangeable components
This paper presents a proposal to integrate mixedreality remote experiments into virtual learning environments (VLEs) using the concept of interchangeable components, which can represent either real or virtual devices or software in industrial automation systems. Combinations of real and virtual technical plants and automation systems are used in different l

11. Computational framework to analyze agrometeorological, climate and remote sensing data: challenges and perspectives.
In the past few years, improvements in the data acquisition technology have decreased the time interval of data gathering. Consequently, institutions have stored huge amounts of data such as climate time series and remote sensing images. Computational models to filter, transform, merge and analyze data from many different areas are complex and challenging. T

12. Monitoring sugar cane crops through dtw-based method for similarity search in NDVI time series.
Brazil is an important sugar cane producer, which is the main resource for ethanol production, a renewable source of energy. Due to the strategical importance of this agricultural commodity, it is necessary to improve models that assist the crops monitoring process. Recently, remote sensing images have also been used to crops monitoring. Vegetation index ima
