Sensing devices are increasingly being deployed to monitor the physical world around us. One class of application for which sensor data is pertinent is environmental decision support systems, e.g. flood emergency response. However, in order to interpret th ...
Goal-Oriented Requirements Engineering (GORE) is considered to be one of the main achievements that the requirements of the Requirements Engineering field has produced since its inception. Several GORE methods were designed in the last twenty years in both ...
Research and teaching have an array of unique hazards which reflect both the variety and the continuous evolution of their operations. These hazards include chemical, physical, biological or technical facets. For example there is an increasing awareness of ...
The demand for richer multimedia services, multifunctional portable devices and high data rates can only been visioned due to the improvement in semiconductor technology. Unfortunately, sub-90 nm process nodes uncover the nanometer Pandora-box exposing the ...
Several challenges should be resolved for three dimensional integration to evolve to a mainstream technology. Among these challenges, the issues of synchronization and power integrity become predominant due to the multiple planes and the heterogeneity of 3 ...

Toxicokinetic-toxicodynamic (TKTD) models quantify the time-course of internal concentration, which is defined by uptake, elimination and biotransformation (TK), and the processes which lead to the toxic effects (TD). TKTD models show potential in predicti ...
The design of effective trust and reputation mechanisms for personal learning environments (PLEs) is believed to be a promising research direction. In this paper, we propose a 4-dimensional trust model that complies with the specific requirements of PLEs. ...
