Many real-time systems have timing requirements that are diicult to fulll if the system is implemented by software running on a microprocessor. One way to remedy this problem is to implement the most time-critical parts in application-speciic integrated circuits instead. Hardware/software codesign aims at providing support for the designer of such a heterogeneously implemented system, and espec...

Providing database support for interactive 3D Visualization and Situational Awareness (SA) is one of the keys to making such systems scale to the complexity of real-world scenarios. It is desirable that SA systems be highly realistic and intuitive to use. From a database perspective these requirements translate into (i) support for large amount of heterogeneous spatio-temporal data (to provide ...

We have explored using neurophysiologic patterns as an approach for developing a deeper understanding of how teams collaborate when solving time-critical, complex real-world problems. Fifteen students solved substance abuse management simulations individually, and then in teams of three while measures of mental workload (WL) and engagement (E) were generated by electroencephalography (EEG). Hig...

In this paper, we concentrate on component adaptation in sensor-actuator networks. Component adaptation is the process of dynamically replacing components in an application in response to changes in the environment conditions. Since the normal operation of a sensor-actuator network is often hindered by faults (e.g., node failures, message losses, synchronization errors), it is important that th...

Anytime algorithms offer a tradeoff between solution quality and computation time that has proved useful in applying artificial intelligence techniques to time-critical problems. To exploit this tradeoff, a system must be able to determine the best time to stop deliberation and act on the currently available solution. When the rate of improvement of solution quality is uncertain, monitoring the...

Why Ethernet? Due to the worldwide deployment of Ethernet in office environments, there is increasing demand for using this technology for networking time-critical embedded applications, too. Seamless transparent communication from within the application to the outside world, based on one single standard, device availability and familiarity with this technology are the main advantages. However,...

The imprecise computation technique was introduced as a way to handle transient overload and to enhance the fault-tolerance of real-time systems. In a system based on this technique, each time-critical task is designed in such away that it can produce a usable, approximate result in time whenever a failure or overload prevents it from producing the desired, precise result. This paper describes ...

This paper describes a vision processing architecture which together with a robotic camera platform and control subsystem comprise a multi-processor real-time system for research into active vision. Experimentation in time-critical aspects of the active vision paradigm over several years has demonstrated the flexibility of “pipe-groups” used as the building block in the system. The design of th...
