Changes to the National Airspace System will occur as part of the Next Generation Air Transport System. The consequences of these changes on the situation awareness of pilots and air traffic controllers need to be identified. Before situation awareness metrics can be deployed towards this goal, metrics that can unambiguously capture baseline levels of situation awareness in the current day Nati...

A common assumption in organizations is that information sharing improves situation awareness and ultimately organizational effectiveness. The sheer volume and rapid pace of information and communications received and readily accessible through computer networks, however, can overwhelm individuals, resulting in data overload from a combination of diverse data sources, multiple data formats, and...

For multi-modular nuclear power plants under the scheme of multiple steam supply system (NSSS) modules driving a single turbine, NSSS are coupled tightly with each other by common giving more complex normal operation respect to single-modular plants. To limit cost plants, one operator is assigned monitor and control two or modules, whose feasibility should be verified. Combined characteristics ...

Situation Awareness involves the comprehension of the state of a collection of objects in an evolving environment. This not only includes an understanding of the objects’ characteristics but also an awareness of the significant relations that hold among the objects at any point in time. Systems for establishing situation awareness require a knowledge representation for these objects and relatio...

A lack of information security awareness within some parts of society as well as some organisations continues to exist today. Whilst we have emerged from the threats of late 1990s of viruses such as Code Red and Melissa, through to the phishing emails of the mid 2000’s and the financial damage some such as the Nigerian scam caused, we continue to react poorly to new threats such as demanding mo...

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...

Pervasive computing is a paradigm that focuses on availability and non-intrusive integration of computing services into everyday life. Context awareness is the basic principle of pervasive computing. The important part of high-level context awareness is situation awareness – the ability to detect and reason about the real-life situations. The specifications of situations are often carried out m...

In this paper we are concerned with event-based situation analysis. Application areas include the understanding and awareness of complex unfolding scenarios such as homeland security threats and future battlespace engagements. The paper (i) discusses the differences between the environments/requirements for event-based management and situation management, (ii) presents an argument for an integr...

When collaborating, individuals rely on situation awareness (the gathering, incorporation and utilization of environmental information) to help them combine their unique knowledge and skills and achieve their goals. When collaborating across distances, situation awareness is mediated by technology. There are few guidelines to help system analysts design systems or applications that support the ...
