A Multioutcrop Sharing and Interpretation System: Exploring 3-D Surface and Subsurface Data

Over the last two decades, rapid technological evolution has brought several advanced solutions for applications in various knowledge areas. Geotechnologies have allowed geoscientists to acquire vast amounts of spatialized digital data, producing equally large data sets. Light detection and ranging (lidar) technology, especially terrestrial laser scanners (TLSs), and the more recent reconstruction techniques that use [...]

Proposal of a Method to Determine the Correlation between Total Suspended Solids and Dissolved Organic Matter in Water Bodies from Spectral Imaging and Artificial Neural Networks

Water quality monitoring through remote sensing with UAVs is best conducted using multispectral sensors; however, these sensors are expensive. We aimed to predict multispectral bands from a low-cost sensor (R, G, B bands) using artificial neural networks (ANN). We studied a lake located on the campus of Unisinos University, Brazil, using a low-cost sensor mounted [...]

Analisando o Estado-da-Arte dos Controllers SDN para a Unificação das camadas Óptica e de Pacotes em redes de Telecomunicações

A partir da entrada de novas tecnologias, redes de telecomunicações estão em constante evolução  e aprimoramento, muitas vezes impulsionadas pelo mercado ou por necessidades apresentadas em projetos das redes em operação. Dentre as atuais evoluções, a tecnologia Software-Defined Networking (SDN) possui forte perspectiva de transformação nas redes de telecomunicações. Em particular, SDN pode atuar na [...]

AgriPrediction: A proactive internet of things model to anticipate problems and improve production in agricultural crops

One of the significant challenges for the future is to guarantee food for all inhabitants of the planet. One of the alternatives for this issue consists in increasing the production, but to accomplish this, it is necessary that innovative options be applied to enhance the soil capacity and the protection of environmental resources. In this [...]

Internet of Health Things: Toward intelligent vital signs monitoring in hospital wards

BACKGROUND: Large amounts of patient data are routinely manually collected in hospitals by using standalone medical devices, including vital signs. Such data is sometimes stored in spreadsheets, not forming part of patients' electronic health records, and is therefore difficult for caregivers to combine and analyze. One possible solution to overcome these limitations is the interconnection [...]

NovaGenesis Applied to Information-Centric, Service-Defined, Trustable IoT/WSAN Control Plane and Spectrum Management

We integrate, for the first time in the literature, the following ingredients to deal with emerging dynamic spectrum management (DSM) problem in heterogeneous wireless sensors and actuators networks (WSANs), Internet of things (IoT) and Wi-Fi: (i) named-based routing to provide provenance and location-independent access to control plane; (ii) temporary storage of control data for efficient [...]

A Última Década do Uso de Internet das Coisas Durante a Triagem de Pacientes no Departamento de Emergência – Um Mapeamento Sistemático

This article presents a systematic mapping of the literature on patient triage in the emergency department of hospitals using the smart devices of the Internet of Things. Method: For this, 533 articles were found in several sources of research; Where, after applying exclusion criteria, there were 16 articles were further analyzed. Result: We identified that [...]

An intensity recovery algorithm IRA for minimizing the edge effect of LIDAR data

The terrestrial laser scanner is an equipment developed for surveying applications and is also used for many other purposes due to its ability to acquire 3D data quickly. However, before intensity data can be analyzed, it must be processed in order to minimize the edge or border effect, one of the most serious problems of [...]

Least trimmed squares estimator with redundancy constraint for outlier detection in GNSS networks

Global navigation satellite system (GNSS) networks facilitate accurate positioning over short and long distances on the surface of the Earth and expand the range of high-precision measurement. These networks are the basis not only for mapping activities, geoinformation, land registry and other location-based services, but also provide an important role in society as infrastructure works [...]
