OOl8-9251/9S/$4.00 @ 1995 IEEE Air crews are faced with critical decisions in an increasingly information-rich environment. While automation handles a greater percentage of procedural operations, the crew retains responsibility for vigilant monitoring, situational awareness, and efficient planning. Strategic decisions that significantly affect the course of the mission must be made under uncert...

The search for train connections in state-of-the-art commercial timetable information systems is based on a static schedule. Unfortunately, public transportation systems suffer from delays for various reasons. Thus, dynamic changes of the planned schedule have to be taken into account. A system that has access to delay information of trains (and uses this information within search queries) can ...

Using potential fields is a technique seldom used in RoboCup scenarios. The existing approaches mainly concentrate on world state representations of single actions such as a kick. In this paper we will show how to apply potential fields to assist fast and precise decisions in an easy and intuitive way. We go beyond the existing approaches by using potential fields to determine all possible play...

Many real-time systems have timing requirements that are diicult to fulll if the system is implemented b y 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. Hardwareesoftware codesign aims at providing support for the designer of such a heterogeneously implemented system, and espe...

The pre-supplementary motor area (pre-SMA) is engaged in speech comprehension under difficult circumstances such as poor acoustic signal quality, cognitive load, or time-critical conditions. Previous studies found left pre-SMA activated when subjects listen to accelerated speech. Here we tested the functional role of the pre-SMA for accelerated speech comprehension by inducing a transient “virt...

A major topic of recent research in graphical models has been to develop algorithms to learn them from a dataset of sample cases. However, most of these algorithms do not take into account that learned graphical models may be used for time-critical reasoning tasks and that in this case the time complexity of evidence propagation may have to be restricted, even if this can be achieved only by ac...

This paper presents scalable solutions for achieving virtual humans able to manipulate objects in interactive virtual environments. The scalability trades computational time with the ability of addressing increasingly difficult constraints. In time-critical environments, arm motions are computed in fewmilliseconds using fast analytical Inverse Kinematics. For other types of applications where c...

The imprecise-computation technique was proposed as a way to handle transient overloads and enhance the dependability of real-time systems. In a system based on this technique, each time-critical task produces an approximate but usable result whenever a failure or overload prevents the system from producing a precise result. This approach makes meeting deadlines easier, increases the availabili...

In this paper new concepts for baggage transport to and from narrow body airplanes are presented. The concepts are simulated and applied to a part of Schiphol Airport Amsterdam. The current baggage transportation is labour intensive and bares the risk of damaging or losing bags. Moreover it is time-critical because of the tight flight schedules used. An alternative scheduling method as well as ...

We present a low cost system for unassisted mobility of blind people built with off-the-shelf technology. Our system takes as input the depth maps produced by the Kinect c ©device coupled with the data from its accelerometer to provide a registered point based 3D representation of the scene in front of the user. We developed a time-critical framework to analyze the scene and classify the ground...
