The aim of this study was to investigate whether nonclinically anxious children, like anxious adults, favor the processing of threatening or concern-related information. Two experiments, using an emotional Stroop task, were carried out in high anxious and low anxious children aged 8 to 9 to examine whether a medical stressor elicited a processing bias. Results indicated that, independently of t...

Considering the high costs of the implementation and maintenance of gas distribution networks in urban areas, optimal design of such networks is vital. Today, urban gas networks are implemented within a tree structure. These networks receive gas from City Gate Stations (CGS) and deliver it to the consumers. This study presents a comprehensive model based on Mixed Integer Nonlinear Programming (...

Qualitative status of the environment is signaled by a group of indicators, known as bioindicators, several of which are responsible for showing progressive impacts of different types of pollutants. Having addressed the influence of various bioindicators in environmental pollution, it has been revealed that bioindicators are sensitive to any disturbance in any environment. With regards to the p...

Situation assessment, i.e. the process of achieving situation awareness, is common in environmental monitoring, where assessment occurs predominantly on sensor data and awareness is for the state of environmental phenomena. For a particular location, an environmental monitoring system may measure and compute mean hourly PM2.5 concentration to acquire knowledge for situations of unhealthy exposu...

As mini-UAVs become more capable and reliable, it is important to start looking at the factors differentiating them from other classes of unmanned vehicles. One such factor is the physical proximity of operators to the vehicle during deployment. Operators of these UAVs are often within sight of their vehicle, and share many environmental cues such as visual landmarks. However, operating in the ...

As environmental monitoring systems increasingly automate the collection and processing of environmental sensor network data, the technical components of such systems can automatically obtain and maintain higher levels of situation awareness—awareness of the monitored part of reality. In order to increase confidence in the correctness of situation awareness maintained by such systems it is impo...
