Integrating Aqua and Terra/MODIS satellite Data for the Evaluation of Heat Stress Impacts on Summer Crops
In this study we analyze the relationship between the occurrence of high temperatures and the variability of soybean yield. The study covers the crop years from 2003 to 2012 in Rio Grande do Sul State. For the analysis of temperature over the vegetation canopy in agricultural areas, we used a LST (Land Surface Temperature ) [...]
Evaluating the Thermal Spatial Distribution Signature for Environmental Management and Vegetation Health Monitoring
An accurate evaluation of the environment while cities are still growing economically is highly necessary for reliable assessment of ecosystem conditions. This research evaluates a comparison between the pattern of Land Surface Temperature (LST) distribution and Enhanced Vegetation Index 2 (EVI-2) during the summer season as an indicator of development conditions in an Area of [...]
Accuracy Analysis of Digital Outcrop Models Obtained from Terrestrial Laser Scanner (TLS)
The analysis, description and interpretation of outcrops are mainly based on field activities from which geoscientists can make observations, descriptions and sketches in field books as well as acquisition of digital photographs and different measurements with compass and other equipaments. The development of geotechnologies in the last decade has been crucial in obtaining geological data [...]
Integrating Collaborative and Decentralized Models to Support Ubiquitous Learning
The application of ubiquitous technologies in the improvement of education strategies is called Ubiquitous Learning. This article proposes the integration between two models dedicated to support ubiquitous learning environments, called Global and CoolEdu. CoolEdu is a generic collaboration model for decentralized environments. Global is an infrastructure designed to create ubiquitous learning environments. Global provides software [...]

Estes aspectos tecnológicos vêm sendo utilizados com sucesso em processos de detecção precoce de comportamentos [...]
A Decentralized Infrastructure for Ubiquitous Learning Environments
This article proposes an infrastructure called Global. The main hypothesis consists in the possible creation of an architecture completely decentralized and extensible, focused in the development of ubiquitous learning environments. The text describes the infrastructure´s architecture. Additionally, the article presents an implementation and a concepts proof through the use of Global in the developing of [...]
A Model for Ubiquitous Transport Systems Support
The use of mobile and ubiquitous computing has been stimulated by the widespread diffusion of mobile devices, wireless networks and location systems. In this context, numerous applications are emerging in different areas such as education, entertainment, commerce and transport. This paper proposes the MD-UTS, a model for development of ubiquitous transport systems. The model allows [...]
