We present tools to visualize density, clustering, and lethality assessment that help a military commander achieve situation awareness (SA) on the battlefield. For the density computation, we provide a geometry-based, image-based, and hybrid approach to tackle the problem. We choose proximity-based clustering as a suitable definition for our application. Based on this clustering definition, we ...

The Event Model (TEM) is a novel computation-independent model targeted at helping non-programmers to define and manage the logic of event-driven applications. The model design is based on a collection of building blocks that comprise a set of diagrams and normalized tables to define the event business logic of an application, a set of principles that define the set of assertions that a correct...

To raise awareness in disaster situations, the quality and analysis of disaster-related big data are essential. Recent developments in the collection, analysis, and visualization of multimedia data have led to a significant enhancement in disaster management systems. Crowdsourcing tools, for instance, allow citizens to perform an active role in reporting information relevant to disaster events ...

Situation Awareness, and how systems can be designed to support it appropriately, have been a focus of study in dynamic, safety critical contexts such as aviation. The work reported here extends the study of situation awareness into the domain of Emergency Medical Dispatch (EMD). The study was conducted in one of the largest ambulance services in the world. In this study, we encountered develop...

Mobile devices as PDAs evolve rapidly from digital calendars and address books to hosts of more complex functionality. Mobile access to business information such as customer, product or project databases is seen as one of the cutting edge IT solutions for improving productivity and customer satisfaction. However, mobility and scaled-down mobile technology lead to specific limitations in contras...

Situation Awareness (SA) is the problem of comprehending elements of an environment within a volume of time and space. It is a crucial factor in decision-making in dynamic environments. Current SA systems support the collection, filtering and presentation of data from different sources very well, and typically also support some form of low-level data fusion and analysis, e.g., recognizing patte...

How well does an algorithm support its purpose and user base? Has automation provided the user with the ability to augment their production, quality or responsiveness? In a number of systems today these questions can be answered by either Measures of Performance (MOP) or Measures of Effectiveness (MOE). However, the fusion community has not yet developed sufficient measures and has only recentl...

This paper is based on the Network security situation awareness. It describes the framework designed to generate security graph. The proposed framework is easy to install and provides protection against denial of service and distributed denial of service attacks. It also displays security analysis of the sensors attached to the network
