Cable termination faults are problematic in electrical networks almost always. Technology has solved problems somewhat, but there are many annual reports about damaged cable terminations. For analyzing the problems, faults in two regional electricity companies are studied. At first step, damaged cable terminations are analyzed statistically and grouped according to their problems. Then, some of...

In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...

Applying prestress is the key technique of the cable dome. However, it is difficult to ensure that designed prestress of cables have been exactly applied to the structure in the site due to the fact that various kinds of errors will be introduced during construction. Thus it is necessary to present an effective method to guide construction to avoid construction team regulate the real prestress ...

The long-span multi-tower suspension bridge is widely used in the construction of river and sea crossing bridges. load-bearing safety anti-sliding its main cable are directly related to structural a bridge. Failure mechanisms discussed. Meanwhile, tribo-corrosion-fatigue cable, contact, slip behaviors saddle service assessment reviewed. Finally, research trends proposed. It great significance i...

UNLABELLED The transmembrane Tsr protein of Escherichia coli mediates chemotactic responses to environmental serine gradients. Serine binds to the periplasmic domain of the homodimeric Tsr molecule, promoting a small inward displacement of one transmembrane helix (TM2). TM2 piston displacements, in turn, modulate the structural stability of the Tsr-HAMP domain on the cytoplasmic side of the mem...

It is essential to construct structural health monitoring systems for large important bridges. Zhijiang Bridge is a cable-stayed bridge that was built recently over the Hangzhou Qiantang River (the largest river in Zhejiang Province). The length of Zhijiang Bridge is 478 m, which comprises an arched twin-tower space and a twin-cable plane structure. As an example, the present study describes th...

We conduct an empirical analysis of quality competition between broadband Internet Service Providers (ISPs), using National Broadband Map data for 2011-2013 for almost a thousand local markets in California. We examine how incumbent ADSL firms respond to competition from CLECs and cable modem service providers. We use an important quality attribute, the downstream data rate, and estimate the st...

workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...
