From the aspect of design and operation, cables and cable accessories are still very actual, although it has been more than a hundred years since the appearance of the first cable. Many questions concerning the construction of cables, cable accessories especially, are still open. In MV and HV systems, cable accessories are one of the weakest links. Cable terminations and joints are designed to ...

We analyze simple morphological configurations that represent gap-junctional coupling between neuronal processes or between muscle fibers. Specifically, we use cable theory and simulations to examine the consequences of current flow from one cable to other gap-junctionally coupled passive cables. When the proximal end of the first cable is voltage clamped, the amplitude of the electrical signal...

The purpose of this study was to clinically examine the relationship between rotator cable integrity and the presence of pseudoparalysis. A retrospective review was performed of a consecutive series of arthroscopic repairs of massive rotator cuff tears performed between January 2007 and June 2009. A total of 127 massive tears were identified. Group 1 comprised 24 patients with preoperative pseu...

INTRODUCTION Vole captive bolt devices are special mouse traps which belong to the spring guns. Devices and ammunition are available over the counter, age of consent (18 years) is the only legal restriction. Loaded with a 700 J cartridge the device is positioned in the vole passage. By slightly touching a metal ring in front of the muzzle the mouse triggers the shoot and is killed by a high-pre...

Two case studies are summarized using anisotropic plasticity and the Weibull weakest link failure model to predict the behavior of wood and wood composites. The linear elastic orthotropic model normally used for wood is shown to be insufficient for the prediction of ultimate strength in wood. Non-linear, non-recoverable behavior in compression in each of the orthogonal material directions is of...

Assembly of off-road bicycle handlebars with a stem that clamps the handlebar around its circumference would be expected to affect fatigue performance by introducing both assembly stresses and stress concentration. Because the effect of clamping on fatigue performance is unknown and because of the need to insure structural reliability in the stem-handlebar assembly to prevent serious injury, th...

OBJECTIVES Fractures of the proximal femur are a common clinical problem, and a number of orthopaedic devices are available for the treatment of such fractures. The objective of this study was to assess the rotational stability, a common failure predictor, of three different rotational control design philosophies: a screw, a helical blade and a deployable crucifix. METHODS Devices were compar...

For cable bridges, the cable tension force plays a crucial role in their construction, assessment and long-term structural health monitoring. Cable tension forces vary in real time with the change of the moving vehicle loads and environmental effects, and this continual variation in tension force may cause fatigue damage of a cable. Traditional vibration-based cable tension force estimation met...

Cable tension force is one of the most important structural parameters to monitor in cable-stayed bridges. For example, cable tension needs to be monitored during construction and maintenance to ensure the bridge is not overloaded. To economically monitor tension forces, this study proposes the use of an automated wireless tension force estimation system (WFTES) developed solely for cable force...

The introduction of carbon-fibre reinforced plastics in load bearing automotive structures provides a great potential to reduce vehicle weight and fuel consumption. A reduction in overall manufacturing cost can be realised through part integration and use of cost-effective materials such as heavy tow carbon fibre. There is a current drive within the automotive industry to develop the technologi...
