An ever-larger availability of devices that are attached with different sensing capabilities (e.g., smart phones) shifted the challenge in activity and context recognition from the application specific deployment of new sensors to the utilization of already available devices. Therefore, a system that operates in an opportunistic way has to take advantage of the currently available sensing infra...

The actual grow of the infrastructure in develop country require sophisticate ways manage the operation and control the quality served. This research wants to concentrate in the operation of this infrastructure beyond the construction. The infrastructure’s operation involves an uncertain environment, where unexpected variables are present every day and everywhere. Decision makers need to make r...

ODUCTION ar sensors with dual-polarization capability etter understanding and characterization of hazards. Advanced knowledge-based hazard algorithms would require better knowledge of ttering characteristics of hydrometeors such as , hailstones, and snowflakes. Especially, characteristics becomes important for utilize phase-array dual-polarization radar Traditionally, theoretical approaches [1]...

Data-centric approaches play an increasing role in many scientific domains, but in turn rely increasingly heavily on advanced research support environments for coordinating research activities, providing access to research data, and choreographing complex experiments. Critical time constraints can be seen in several application scenarios e.g., event detection for disaster early warning, runtime...

The extreme use of mobile phones has magnified the quantity of digital knowledge created and processed on a daily basis. Participatory Sensing (PS) is associated paradigm that focuses on the collection of digital knowledge created from an oversized variety of connected, always-on, alwayscarried mobile devices. PS takes the advantage of fast movement of the sensor-equipped devices and therefore ...

The research focus on study, analyze and d esign the model of the infrastructure and computer networks for distance education, online learning via new media, e-learning and blen ded learning. The collected information from study and analyze process that information was evaluated by the index of item objective congruence (IOC) by 9 specialists to design model. The results of evaluate the model w...

This work presents an infrastructure that simplifies the development of distributed applications that can adapt automatically to nonfunctional properties of their components and of their execution environment. This infrastructure, based on the programming language Lua and on CORBA, allows applications to select dynamically the components that best suit their requirements, to verify whether the ...

“Resilience” describes how systems operate at an acceptable level of normalcy despite disturbances or threats. In this paper we first consider the interdependencies inherent in critical infrastructure systems and how resilience mitigates associated risks and then define “resilience” in distinction from convention control engineering. We then introduce the concepts “agent” and “multi-agent syste...

Wireless Sensor Networks can help to mitigate the problem of congestion in cities. Congestion occurs, when the road infrastructure cannot cope with the increased demand for the particular road segment. This paper presents a congestion control system, which uses sensors installed on the road side units to monitor the data and the cars also having the capacity to collect data from the road infras...

EUBrazilOpenBio is a collaborative initiative addressing strategic barriers in biodiversity research by integrating open access data and user-friendly tools widely available in Brazil and Europe. The project deploys the EU-Brazil Hybrid Data Infrastructure that allows the sharing of hardware, software and data on-demand. This infrastructure provides access to several integrated services and res...
