River widening is commonly used as a solution for the rehabilitation of rivers with the main purposes of allowing the river to adjust to its natural dynamics and to improve riparian and instream habitat for flora and fauna, by increasing the heterogeneity in substrate, flow and morphology. Local widening may also be used for confluences rehabilitation as, for many of them, the heterogeneity and...

The mobile platform described in this paper is a holonomic type robotic vehicle. It is designed for use as a slave system in the development of a fault-tolerant teleoperation test-bed system. Therefore, the vehicle itself has a fault-tolerant design. This paper reviews the previous designs of mobile platforms, introduces several conceptual designs and the final design. Initial component selecti...

This paper describes the work done in autonomous operation of mobile robot at the Canadian Space Agency. The Mobile Robotic Test bed (MRT) components are presented. The autonomy software, implemented using a behaviour-based approach, is presented. The peripheral sub-systems used by the reactive engine, such as vision and path planner are also described.

This paper describes a wireless mobile ad hoc network test bed developed at the University of Colorado, Boulder. The test bed is a framework on which one can run any ad hoc routing protocol implementation and collect performance statistics using benchmark tests. The results are reproducible and the performance statistics collected can be analyzed at a minute level. The test bed closes the gap b...

BACKGROUND Bed rest is a traditional treatment for back pain, yet only in recent years has the therapeutic benefit of this been questioned. AIM The aim of this pilot study was to ascertain whether or not 48 hours' bed rest had an effect on the outcome of acute low back pain. METHOD The study was conducted as a randomized controlled trial to compare a prescription of 48 hours' strict bed res...

The proposed research work presents a novel approach of process oriented architecture for secure mobile commerce framework using uniquely designed hybrid mobile adhoc routing protocols using reactive and proactive type in real time test-bed. The research work discusses about deployment of mobile commerce which is one of the emerging trend in mobile applications with huge demands. Majority of th...

Recent emergence of bed bugs (Cimex spp.) has prompted a significant expansion of research devoted to this pest. The ability to survive and recover from stress has significant implications on the distribution and survival of insects, and bed bugs are no exception. Research on bed bug stress tolerance has shown considerable progress and necessitates a review on this topic. Bed bugs have an extra...

Abstract This paper summarizes the advantages of mobile health care in management family hospital beds, and puts forward suggestions for future Chinese bed patients.
