In this paper, we introduce a Resource Reservation Protocol (RSVP) benchmark to investigate the RSVP protocol through profiling. The benchmark is created by modifying an existing C implementation of RSVP. By running the modified benchmark in a simulation environment, two kinds of profiling results were gathered. First, performance-related results were produced to identify the time-critical func...

As agents begin to perform complex tasks alongside humans as collaborative teammates, it becomes crucial that the resulting humanmultiagent teams adapt to time-critical domains. In such domains, adjustable autonomy has proven useful by allowing for a dynamic transfer of control of decision making between human and agents. However, existing adjustable autonomy algorithms commonly discretize time...

Time Petri nets (TPNs) are a popular Petri net model for specification and verification of real-time systems. A fundamental and most widely applied method for analyzing Petri nets is reachability analysis. The existing technique for reachability analysis of TPNs, however, is not suitable for timing property verification because one cannot derive end-to-end delay in task execution, an important ...

Although the technology of expert systems has been developed substantially during the past decade, there still seems to be relatively little application to time-critical problems because of their extensive computational requirements. One application area of particular interest is that of process control. Because this area requires real-time operation, the expert system must operate within the t...

Several convenience and efficiency applications have been proposed as part of recent vehicular networks (a.k.a. VANET) activities. Among these proposals, eHealth has often been studied as a time-critical application to emulate an ambulance. The Vehicle-To-Infrastructure (V2I) setting is the typical communication scenario to carry out the data in this case. From a user perspective, combining veh...

regulatory rules (Eisenhardt, 1989) and often involve Decison-making dilemmas can arise because errors stress due to the need to make choices under time presmay result either from deciding too soon or from desure. However, such time stress is often due not so laying decisions too long. Delay can result in lost opmuch to strict deadlines as it is to the potential opporportunities or reductions i...

In computer graphics, it is often an advantage to calculate refractions directly, especially when the application is time-critical or when line graphics have to be displayed. We specify efficient formulas and parametric equations for the refraction on straight lines and planes. Furthermore, we develop a general theory of refractions, with reflections as a special case. In the plane case, all re...

In this paper, a novel target acquisition and localisation algorithm (TALA) is introduced that offers a capability for detecting and localising multiple targets using the intermittent “signals-of-opportunity” (e.g. acoustic impulses or radio frequency transmissions) they generate. The TALA is a batch estimator that addresses the complex multi-sensor/multi-target data association problem in orde...

Speaker diarization is the task of partitioning an audio stream into homogeneous segments according to speaker identity. Today state-of-the-art speaker diarization systems have achieved very competitive performance. However, any small improvement in Diarization Error Rate (DER) is usually subject to very large processing times (real time factor above one), which makes systems not suitable for s...

PERTS is a prototyping environment for real-time systems. It is being built incrementally and will contain schedulers and resource access protocols for time-critical applications, together with tools and a simulation environment for the analysis, validation, and evaluation of real-time systems built on the scheduling paradigms supported by these building blocks. Specifically, PERTS is designed ...
