The paper presents a sampling period dependent RST controller used in the context of control/scheduling co-design. This plant controller is implemented on a real-time operating system as a control task. A scheduling controller adapts control task periods to regulate the processor load. The link established between scheduling and plant control provides more flexibility and robustness w.r.t. the ...

The Multimodal User Supervised Interface and Intelligent Control (MUSIIC) project is working towards the development of an assistive robotic system which integrates human-computer interaction with reactive planning techniques borrowed from artificial intelligence. The MUSIIC system is intended to operate in an unstructured environment, rather than in a struc-tured workcell, allowing users with ...

The intensive I/O generated by multimedia devices and delivered over fast networks requires a new approach to U0 system software design for workstation operating systems. In general, the system should provide more flexibility in how devices are controlled and in constructing the data paths used for data transfer. I argue for the separation of control and data transfer as a general design princi...

Kea is a new operating system kernel which has been designed for maximum flexibility and performance in the areas of kernel and application extensibility and dynamic reconfiguration. Kea provides a means through which kernel services can be reconfigured, either on an application specific or system wide scale. We describe the design and implementation of these features, and report on some of our...

support vector regression (svr) is a learning method based on the support vector machine (svm) that can be used for curve fitting and function estimation. in this paper, the ability of the nu-svr to predict the catalytic activity of the fischer-tropsch (ft) reaction is evaluated and the result is compared with two other prediction techniques including: multilayer perceptron (mlp) and subtractiv...

Multiprocessor systems are becoming increasingly popular because of the increased throughput possible and the possibility of system availability despite the failure of some of the processing units. This paper describes an innovative concept in multiprocessor system design, and suggests some of the research areas which have not yet been resolved but which can be studied on this system. The syste...

(Eine inhaltsgleiche, deutsche Fassung dieser Übersicht ist ab Seite 243 zu finden.) The design of current operating systems and their kernels shows deficiencies in respect to the structuring approach and the flexibility of their protection systems. The operating systems and applications suffer under this lack of extensibility and flexibility. The protection model implemented in many operating ...

BACKGROUND The relationship between age-related frailty and the underlying processes that drive changes in health is currently unclear. Considered individually, most blood biomarkers show only weak relationships with frailty and ageing. Here, we examined whether a biomarker-based frailty index (FI-B) allowed examination of their collective effect in predicting mortality compared with individual...
