Internet of Things (IoT) brings the third development wave of the global information industry, which makes users, network, and perception devices cooperate more closely. However, if IoT has security problems, it may cause a variety of damage and even threaten human lives and properties. To improve the abilities of monitoring, providing emergency response, and predicting the development trend of...

Many organizations are implementing recommender systems with the expectation to influence users’ actions. However, research has shown that poorly designed recommender systems may be counterproductive. For instance, if a recommender system provides too many recommendations, users cannot focus on relevant recommendations anymore. Therefore, recommender systems need to be balanced and adjusted to ...

Three deficiencies exist in information security under prevailing practices: organisations tend to focus on compliance over protection; to estimate risk without investigating it; and to assess risk on an occasional (as opposed to continuous) basis. These tendencies indicate that important data is being missed and that the situation awareness of decision-makers in many organisations is currently...

Decentralized command and control settings like those found in the military are rife with complexity and change. These settings typically involve dozens, if not hundreds to thousands, of heterogeneous players coordinating in a distributed fashion in a dynamically networked battlefield laden with sensor data, intelligence reports, communications, and plans emanating from many different perspecti...

The real-time manned-unmanned teaming of on-the-move Army assets will provide mobile commanders and warfighters with improved situation awareness from the sharing and fusion of heterogeneous distributed data sources information. Lockheed Martin Advanced Technology Laboratories (ATL) is improving situation awareness through three ATL-developed technologies: adaptive, modular, multisensor informa...

Situation awareness for ground combat vehicles is being actively developed by the U.S. Army to enable soldiers and commanders to have a better understanding of their environments and hence allow them to fight smarter. The control of hit avoidance assets (sensors and countermeasures) by the Commander‟s Decision Aid (CDA) can also benefit from situation awareness data, either from offboard report...

Situation awareness in large-scale control systems such as road traffic management aims to predict critical situations on the basis of spatio-temporal relations between real-world objects. Such relations are described by domain-independent calculi, each of them focusing on a certain aspect, for example topology. The fact that these calculi are described independently of the involved objects, is...

Within the framework of a joint technical research cooperation project between Brazil and France, this paper proposes a new type of situation awareness algorithm based on the theory of graphs of pairs of plots (cf. Radar conference IEEE Washington 2010: “Tracking based on graph theory applied to pairs of plots”) using Brazilian Navy Aircraft Carrier "São Paulo" as a sensor data platform for the...

With the emergence in research addressing cyberphysical systems, problems that previously were ignored or thought to be too complex, can now be investigated. A particular problem which we consider in this paper is that of environmental mapping and monitoring immediately following a natural disaster or hazardous contamination to obtain situation awareness. With the tight integration of control, ...
