Situation awareness modelling is popularly used in the command and control domain for situation assessment and decision support. However, situation models in real-world applications are typically complex and not easy to use. This paper presents a Context-aware Decision Support (CaDS) system, which consists of a situation model for shared situation awareness modelling and a group of entity agent...

Security situation awareness is a new technology about security. This paper brings it to the assessment of security situation of metro station which serves as a new way to secure the security of passengers as well as the operation of the metro station. This paper sets up an index system for assessing the security situation awareness and makes a prediction model for the security situation of met...

This paper presents a comparative study on the usage of digital elements in networked collaborative virtual environments (NCVE). The focus of this study is to explore the characteristic of digital elements that promote social awareness. Social awareness is defined as the understanding of a contextual situation at a present time. In networked collaborative virtual environments (NCVE), awareness ...

The purpose of the present experiments was to investigate the generation of conscious awareness (i.e., of verbal report) in an incidental learning situation. While the single-system account assumes that all markers of learning, verbal or nonverbal, index the same underlying knowledge representation, multiple-systems accounts grant verbal report a special status as a marker of learning because t...

Pilots of high-performance military aircraft rely on enormous amount of information from various instruments, visual display from computer and audio communication from outside references. Under high-stressed, visibility-impaired or distracting conditions, even experienced pilots may fail to perceive the information correctly. In particular, a loss of situational awareness such as spatial orient...

Situation awareness is a powerful paradigm that can efficiently exploit the increasing capabilities of handheld devices, such as smart phones and PDAs. Indeed, accurate understanding of the current situation can allow the device to proactively provide information and propose services to users in mobility. Of course, to recognize the situation is a challenging task, due to such factors as the va...

System integration, interoperability, just in time delivery, window of opportunity, and dust-to-dust optimization are all keywords of our computerized future. Survivability is an important concept that together with dependability and quality of service are key issues in the systems of the future, i.e. infrastructural systems, business applications, and everyday desktop applications. The importa...
