Emerging applications are becoming increasingly dynamic, adaptive and context-aware in areas such as just-in-time location-based m-commerce, situational health monitoring, and dynamic social networking collaboration. Although numerous systems and implementation infrastructures have been proposed to deal with some features of such systems, there is a lack of higher-level modeling abstractions an...

Today, the overwhelming volume of information that is available to an increasingly wider spectrum of users creates the need for personalization. In this paper, we consider a database system that supports context-aware preference queries, that is, preference queries whose result depends on the context at the time of their submission. We use data cubes to store the associations between context-de...

This paper describes some of the complexity that needs be captured in any location model of an intimate environment. We take the position that a location model for such an environment must be part of a wider framework for handling context that includes knowledge of people, devices and their communication abilities. We present an ontology based on a general object model of people and devices to ...

NEURONAL MORPHOLOGIES ARE PIVOTAL FOR BRAIN FUNCTIONING physical overlap between dendrites and axons constrain the circuit topology, and the precise shape and composition of dendrites determine the integration of inputs to produce an output signal. At the same time, morphologies are highly diverse and variant. The variance, presumably, originates from neurons developing in a densely packed brai...

Modeling of realistic garments is essential for creating believable virtual environments. Sketch-based modeling of garments presents an appealing, easy to use alternative to the established modeling approaches which are time consuming and require significant tailoring expertise. Unfortunately, the results created using existing sketch-based methods lack realism. Driven by human perception of ga...

This article presents an approach to Web Engineering which aims to account for context-awareness in a comprehensive and integrated fashion, thus enabling an enhanced adaptation of the application to the end-user. A conceptual model, permitting the combination of a domain ontology with context-relevant parameters and a degree of relevance, is presented. Subsequently, the use of such a model in a...

Ubiquitous computing environment consists of diverse range of hardware and software entities, and is about the interactivity of such entities. Context-awareness, being an important ingredient plays a vital role in enabling such interactive smart environments. The entities and contextual information provided/utilized by them must have invariant meanings in order to have a common understanding am...

Context-aware computing refers to a general class of mobile systems that can sense their physical environment, and adapt their behavior accordingly. In this paper we seek to develop a systematic understanding of context-aware computing by constructing a formal model and notation for expressing context-aware computations. This discussion is followed by a description and comparison of current con...

Many real-work smart environments make use of IoT to be provided with context-aware services. Additionally, these environments require making decisions based on predictions about future actions. This involves the use of goal-directed behaviour which may need reasoning about new goals. This paper is devoted to analyze when a new goal can be formulated. Once a plan has been computed for a given p...
