To describe the architecture of iPOS (short for iPAQ positioning system), a novel fault‐tolerant and adaptive self‐positioning system with quality‐of‐service (QoS) guarantees for resource‐limited mobile devices.
The iPOS architecture is based on a novel sensor modelling technique in combination with a probabilistic data‐fusion engine, which is capable of efficiently combining the location information obtained from an arbitrary number of heterogeneous location sensors. As a proof of concept, the paper present a prototypical implementation for handheld devices, which was evaluated by means of practical experiments.
A major advantage of the iPOS positioning system is its extensibility and flexibility, which is achieved by means of an open plugin architecture and the support of global positioning coordinates according to the WGS‐84 standard. The iPOS system scales very well with respect to the number of sensor plugins that can be operated in parallel. The main limiting factor for the number of supported active plugins is the amount of available system resources on the MoD. With regard to recognition, the experimental results indicate a good accuracy of the fusion‐based positioning system in comparison to the accuracy of the individual sensing technologies. Thanks to the explicit modelling of reliable sensor events, the iPOS system is capable of providing QoS guarantees to applications with regard to the achieved positioning accuracy.
During the experiments, the author recognized time synchronisation as an important challenge that should be addressed as part of future work.
The system enables resource‐restricted mobile devices and computerised objects to exploit computing resources found in their immediate physical vicinity (locality).
The paper presents a novel lightweight sensor‐fusion architecture for fault‐tolerant and adaptive self‐positioning that performs well on resource‐limited mobile devices. A special feature of the developed data‐fusion architecture is the application of a novel event modelling technique that enables the positioning system to give QoS guarantees under certain conditions.

Questioning gender is about taking an active, critical role in the technological design of our daily behaviour. It is a deconstruction of the oppositions that exist in the discourses of Ambient Intelligence designers, the ICT industry and computer scientists. What underlies the assumption that Ambient Intelligence will, by disappearing into our environment, bring humans both an easy and entertaining life? The gender perspective can uncover power relations within the promotion and realisation of Ambient Intelligence that satisfy an obvious wish for a technological heaven. The deconstruction of the promise of progress and a better life reveals what is overvalued, what is undervalued and what is ignored. This paper is a deconstruction of the view, currently prevalent in the discourses of Ambient Intelligence; a view of humans and the way they live. A view that will influence the way women and men will be allowed to construct their lives.
There have been several developments during the past year that will aid biologists in their constant battle to keep up with the scientific and technical literature. The Institute for Scientific Information (ISI) has introduced three new online services that are designed for current awareness and retrospective searches: ISI/CompuMath — access to pure and applied math literature; ISI/ISTP&B — index to scientific proceedings and books; and ISI/BIOMED — research front specialties in biomedicine.
Stuart Soloway, previously managing director of Shoppers Paradise, has left the food trade and become retail operations director with Burton Retail, part of the Burton Group. In his new post, in conjunction with two merchandise directors, he is responsible for 350 Burton stores.

This article aims to examine empirically the relationship between budget periodicity and expenditure volatility in state governments. Using a large panel dataset for fifty states over the years 1960-2012, after controlling for institutional, economic, and political factors, we find general expenditure of biennial states has been significantly less volatile than that of annual states. The finding suggests that a choice between annual and biennial budget period can emerge as a feasible and effective countercyclical strategy to overcome fiscal difficulties in the short run and promote fiscal stability in the long run.

Remarks on the parallel in the basis of the riches of the aristocracy and plutocracy. Illustrates the argument from the history of the development of the cotton textile industry, the underpinnings for its growth being the inventions prior to and during the eighteenth century. Exemplifies the part of inventions as the begetter of plutocratic wealth. Sir Richard Arkwright, notably, was its salacious issue.
