The fields of artificial reality and conventional telerobotics share many common technological challenges. In this paper we discuss the concept of applying techniques of virtual environment simulation to address some of the challenges of remote manipulation of teleoperated systems in unstructured environments, with a focus on remote excavation. We first present a taxonomy of factors for disting...

Responsive Link is a communication standard as specified in ISO/IEC 24740:2008 for distributed real-time environments. Responsive Link has multiple features to meet both hard and soft real-time requirements. Unfortunately, current real-time operating systems do not support the main features of Responsive Link. In addition, distributed realtime systems in noisy environments require revealing the...

Testing distributed applications over the Internet is fraught with problems: due to the inability to control a wide area network consistent, reproduceable performance experiments are not possible. Here a system is described that uses a parallel discrete event simulator that can act as a real-time network emulator. Real Internet Protocol (IP) traffic generated by application programs running on ...

Speech recognition in highly-reverberant real environments remains a major challenge. An evaluation dataset for this task is needed. This report describes the generation of the Highly-Reverberant Real Environment database (HRRE). This database contains 13.4 hours of data recorded in real reverberant environments and consists of 20 different testing conditions which consider a wide range of reve...

The Graphics Environment for Max, or GEM, is a real-time computer graphics language which operates under the SGI version of Max. GEM supports abstract computer graphics as well as image and pixel manipulations, enabling the user to control the graphics as objects, instead of as a sequence of vertices. Because it maintains the Max paradigm, GEM is an easy to use development environment.

Knowledge of the location of people and things has always been a valuable commodity. The explosion of new devices and techniques has brought people and item tracking out of the experimental stage and into the wider world. Using Wi-Fi signals is an attractive and reasonably affordable option to deal with the currently unsolved problem of widespread tracking in an indoor environment. HABITS (Hist...

The Open Software Foundation (OSF) Research Institute (RI) is developing a series of operating systems prototypes with the purpose of extending the capabilities of commercial operating systems. The initial goal is to develop a trusted, scalable, real-time operating system environment. Some projects are complete and have been incorporated into commercial operating systems. Current projects focus...

Non-classical embedded real-time systems are characterised by in comparison to classical hard real-time systems less strict timing but more strict economic constraints. It is not possible to build such systems based on worst-case assumptions, since often, the worst-case to average-case ratio is rather bad. This calls for a new platform. A promising approach is to run an off the shelf non-real-t...

For real-time and embedded systems, limiting the consumption of time and memory resources is often an important part of the requirements. Being able to predict bounds on the consumption of such resources during the development process of the code can be of great value. In this paper, we focus mainly on memory-related bounds. Recent research results have advanced the state of the art of resource...
