When interacting with applications, users are less restrictive in disclosing their personal data than if asked in an application-independent context. On a more general level this behavior is termed as privacy paradox. The creation of privacy awareness can assist users in dealing with contextaware services without harming their privacy unintentionally, thereby addressing the privacy paradox. The...

This chapter introduces intelligent technologies applied in electronic healthcare systems and services. It presents an overview of healthcare technologies that enable the advanced patient data acquisition and management of medical information in electronic health records. The chapter presents the most important patient data classification methods, while special focus is placed on new concepts i...

Context-aware systems must be able to deal with uncertain context information. We propose a generic context architecture and representation that incorporates the uncertainty of context elements in terms of upper and lower bounds of probabilities. It is shown how opinion nets can be used to reason with these upper and lower bound probabilities. In this way it is possible to combine ambiguous or ...

The context aware systems are often designed and implemented based on a specific scenario with predefined resources. In this paper, we describe a ubiquitous interactin space that supports rapid context-aware applications reflecting the smart interaction space with dynamic resources and provides a programmable interface in integrated development environment (IDE) in .NET framework.

Smart devices have pervaded our society and encouraged lifestyles that depend on them. One of the fundamental requirements for a successful dependency is that the general public be aware of the energy limitations of these devices and to stay in control of energy consumption. In this paper, the authors propose a formal specification method that takes energy into account. They propose two develop...

This paper examines the use of surveys in measuring privacy concerns in ubiquitous computing environments. Two evaluation techniques are used to study the privacy concerns of sharing context information: a paper based survey and in-situ questionnaires. Results from the two techniques differ significantly, suggesting that surveys are not reliable in predicting privacy concerns regarding context-...

Diagnosis is the first analysis step for uncovering the root cause of failure for a defective integrated logic circuit. The conventional objective of identifying failure locations has been augmented with various physically-aware diagnosis techniques that are intended to improve both resolution and accuracy. Despite these advances, it is often the case, however, that resolution, i.e., the number...

Through an iterative design approach, we have proposed and evaluated ways of incorporating user-created information into context-aware systems. We implemented and tested a location-sensitive college campus tour guide called Campus Aware that allows users to annotate physical spaces with text notes. The goal was to provide visitors to the campus with a sense of the activities going on in the env...

Context-aware systems acquire and integrate multi-faceted knowledge about their environments in order to make decisions. A number of attempts to build frameworks for context-aware systems have been made, but these have not provided adequate support for context-aware access control. In this paper, we present a framework for context-aware access control and its prototype implementation. The frame...

Time aware systems claim for an explicit representation of time-related concepts, so that they can be observed and possibly controlled at run-time. The paper identifies a set of architectural abstractions capturing such concepts related to time and classifies the base activities performed by a time aware system. Our proposal has been formalized using two different modeling techniques: UML and P...
