Understanding the impact of circuit-level inaccuracy on sensor network performance

Energy efficiency is of paramount importance in designing low-power wireless sensor nodes. Approximate computing is a new circuit-level technique for reducing power consumption. However, the gain in power by applying this technique is achieved at the cost of computational errors. The impact of such inaccuracies in the circuit level of a radio...

Lost in persuasion A multidisciplinary approach for developing usable, effective, and reproducible persuasive technology for health promotion

Despite its acknowledged benefits for health promotion, the full potential of persuasive technology is not (yet) reached in regard to usability, effectiveness, and reproducibility. It often lacks an effective combination of technical features and behavior change strategies. This paper presents a multidisciplinary approach, addressing both...

The upcoming and proliferation of ubiquitous technologies in products and processes

Ubiquitous computing is a research field that started in the late 1980s, and is now believed to be at the brink of a steep acceleration in terms of technology development and applications. Ubiquitous computing is often regarded as the third wave of computing, after a first wave of mainframe computing and a second wave of PC computing. It aims at...

Effective and Efficient Communication of Information

Research fields such as Network Enabled Capabilities, ubiquitous computing and distributed sensor networks, etc. deal with a lot of information and a lot of different processes to fuse data to a desired level of situation awareness. Already quite some research is done in applying information theoretic concepts to sensor management. Effective...

Private handshakes

Private handshaking allows pairs of users to determine which (secret) groups they are both a member of. Group membership is kept secret to everybody else. Private handshaking is a more private form of secret handshaking [BRS+03], because it does not allow the group administrator to trace users. We extend the original definition of a handshaking...

First experiences with Personal Networks as an enabling platform for service providers

By developing demonstrators and performing small-scale user trials, we found various opportunities and pitfalls for deploying Personal Networks (PNs) on a commercial basis. The demonstrators were created using as many as possible legacy devices and proven technologies. They deal with applications in the health sector, home services, tourism, and...

On the definition and relevance of context-awareness in Personal Networks

Personal Networks (PNs) enable users to be connected with their devices and services at any time and any place. Context-Awareness will further enrich PNs. This paper shows some examples, presents definitions of Context and Context-Awareness for PNs, and introduces a high-level architecture for Context-Awareness that is tailored to PNs.

Space autonomy as migration of functionality: The mars case

This paper develops Grandjean and Lecouat's insight that spacecraft autonomy can be seen as the migration of functionality from the ground segment to the space segment. Their insight is extended to manned planetary exploration missions and applied to an IT-based crew assistant for supporting manned and unmanned Martian operations. The Mission...

Using home networks to create atmospheres in the home: Technology push or (latent) user need?

The Atmosphere Controller is an implementation of home networking technology that could make life at home a totally new experience. An atmosphere is created by combining light (intensity and colour), music and wallpaper projection. To find out if is this type of experience fits into everyday life of people, we studied the current experience of...
