In this paper, a new approach in human identification is investigated. For this purpose, a standard 12-lead electro-cardiogram (ECG) recorded during rest is used. Selected features extracted from the ECG are used to identify a person in a predetermined group. Multivariate analysis is used for the identification task. Experiments show that it is possible to(More)
Intelligent mobile robots need the ability to integrate robust navigation facilities with higher level reasoning. This paper is an attempt at combining results and techniques from the areas of robot navigation and of intelligent agency. We propose to integrate an existing navigation system based on fuzzy logic with a deliberator based on the so-called BDI(More)
Research on execution monitoring in its own is still not very common within the field of robotics and autonomous systems. It is more common that researchers interested in control architectures or execution planning include monitoring as a small part of their work when they realize that it is needed. On the other hand, execution monitoring has been a well(More)
Track-etch detectors made of cellulose nitrate (LR 115, Kodak Pathé) and polycarbonate (CR 39, Pershore Mouldings Ltd) were compared regarding sensitivity and background when used as detectors for boron determination in biological samples. Measurements were made on two kinds of sample, cryosectioned biological tissue, and liquid samples deposited directly(More)
Autonomous agents operating in complex dynamic environments need the ability to integrate robust plan execution with higher level reasoning. This paper describes work to combine low level navigation techniques drawn from mobile robotics with deliberation techniques drawn from intelligent agents. In particular, we discuss the combination of a navigation(More)
Individuals with severe multiple disabilities have little or no opportunity to express their own wishes, make choices and move independently. Because of this, the objective of this work has been to develop a prototype for a gaze-driven device to manoeuvre powered wheelchairs or other moving platforms. The prototype has the same capabilities as a normal(More)
In the near future, autonomous mobile robots are expected to help humans by performing service tasks in many different areas, including personal assistance, transportation, cleaning, mining, or agriculture. In order to manage these tasks in a changing and partially unpredictable environment without the aid of humans, the robot must have the ability to plan(More)
Autonomous robots need the ability to plan their actions and to execute them robustly and in a safe way in face of a changing and partially unpredictable environment. This is especially important if we want to design autonomous robots that can safely co-habitate with humans. In order to manage this, these robots need the ability to detect when the execution(More)
In this paper we present some preliminary results on the idea of using a model-free execution monitor on a mobile robot. By model-free monitoring we mean that the monitoring is based only on the actual execution, without involving any predictive models of the controlled system. In this, our approach is different from most previous work on execution(More)
Seven cell lines were analyzed for clonogenic survival after irradiation with photons (60Co) or accelerated helium or nitrogen ions. The cell lines showed different sensitivity to photon radiation and most of the differences decreased after irradiation with helium ions with a linear energy transfer (LET) of about 40 keV/microns. However, all cell types had(More)
