We present a runtime environment that partially reconfigures and executes hardware tasks on Xilinx Virtex. To that end, the FPGA’s reconfigurable surface is split into a varying number of variable-sized vertical task slots that can accommodate the hardware tasks. A bus-based communication infrastructure allows for task communication and I/O. We discuss the design of the runtime system and its p...

The Virtual Environment Operating System: Derivation, Function and Form.

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...

The purpose of this paper is to present a comprehensive bibliography of neural network application research in business during the period of 1994}1998. Our extensive literature searches have identi"ed a total of 302 research articles. A classi"cation of these articles by year reveals that a large amount of research has been published in the last "ve years. Production/operations, "nance, marketi...

Processing on the Amoeba distributed operating system is not fault-tolerant. The only concern of its processing service is to perform load balancing on the existing processors, trying to find the processor that best suits a particular process in terms of memory availability and CPU speed. In this paper we introduce a fault-tolerant processing service for the Amoeba system. This service is used ...

Passwords are the linchpin in the security of an increasing number of online services – services that range from social networking to business communication to banking. Given their importance, it is unfortunate that passwords are relatively easily stolen using a number of different types of attack. We introduce HyperPass: an approach and proof-of-concept system that aims to prevent some of thes...

Portable and affordable assistive devices are calling necessities for the physically challenged population putting forth the requirement of designing embedded systems tuned to specific assistive applications. In this paper, we present a low footprint embedded operating system, OaSis, which forms the core of embedded devices being developed for the speech impaired, the visually impaired and thos...

BACKGROUND The rate of surgical site infections (SSI) is strongly influenced by operating room quality, which is determined by the structural features of the facility and its systems and by the management and behavior of healthcare workers. The aim of the present study was to assess microbial contamination in the operating room during hip- and knee-replacement procedures, the behavior of operat...

Sensor-based control of multiple robot systems require a large number of sensors and robotic motor units to be integrated. As the demand for agile manufacturing cells to become more adaptable and reconfigurable in terms of both hardware and software increases, data management and coordination of the numerous connected units become difficult. To attain this flexibility or agility, an operating s...
