Thirty patients with chronic pain due to osteoarthrosis (OA) of the knee were enrolled in a randomised double-blind cross-over trial of self-administered transcutaneous electrical nerve stimulation (TENS) and placebo TENS. Medication was standardised to paracetamol tablets only. As measured on visual analogue scales for pain relief 46% of patients responded to active therapy and 43% to placebo....

In this paper, we explore the vital rescue and relief application of wireless mobile ad hoc networks for the emergency situations. The self-organizing and decentralized features of ad hoc networks make them suitable for a wide variety of applications. We propose to study the efficiency of some routing and MAC protocols under the Client-Server architecture. The presence of dynamic and adaptive r...

The requirements that are placed on today’s grid are changing. Traditional power flows from power stations to the nearest big city are giving way to more complex patterns. Growing consumption and power trading mean that power must increasingly be transported over large distances. Growth in the use of renewable sources is placing a strain on the system because generation is often located in remo...

[1] Changes in gravity due to volcanic loading of the crust are influenced by topography. We investigate the relative importance of topography and self-gravitation in the interpretation of gravity changes. It is shown that modeling of gravity changes can be more precise with the introduction of topographic relief, although it is neglected self-gravitation of the medium. This paper exploits this...

This paper extends the recovery of structure and motion to image sequences with several independently moving objects. The motion, structure, and camera calibration are all a-priori unknown. The fundamental constraint that we introduce is that multiple motions must share the same camera parameters. Existing work on independent motions has not employed this constraint, and therefore has not gaine...
