Power cable is widely used in Extra High Voltage (EHV), High Voltage (HV) transmission, Medium Voltage (MV) sub-transmission, and MV / Low Voltage (LV) distribution applications. Basically, the protection principles used for cable are similar with the ones for overhead transmission line. However, the inherent characteristics of cables make its fault behavior more complicate than that of transmi...

This paper deals with the kinetostatic model for a planar point mass cable-driven parallel manipulator when the cable elasticity and configuration have been fully taken into account. An exact model solution for the statics is obtained by consider elastic hefty cables. The proposed formulation allows considering specific behavior of cables for large dimensions cable-suspended robots in which the...

This case report illustrates hip joint pain caused by electromagnetic waves following an operation for a complex humerus fracture. The subject was a 22-year-old woman. The patient complained of pain in her left hip joint and discomfort, particularly while walking. The subject suffered a fracture in her left upper arm in a traffic accident approximately 3 months previously. She underwent an oper...

We evaluated the efficacy of the systemic insecticides dinotefuran, emamectin benzoate, fipronil, and imidacloprid for preventing attacks and brood production of southern pine engraver beetles (Coleoptera: Curculionidae: Scolytinae) and wood borers (Coleoptera: Cerambycidae) on standing, stressed trees and bolt sections of loblolly pine, Pinus taeda L., in eastern Texas. Emamectin benzoate sign...

in this paper the rehabilitation of concrete structures with a new system is considered. in this system pre- stressed cables with energy dissipating viscous spring dampers at the end of each cable, are used to increase structure lateral stiffness. cable system can be replaced with other system due to their high tensile resistance, their easy replacement, high speed performance, economical matte...

accommodation of mechanism with human being’s physical characteristics creates the possibility of safe and efficient interaction between human being and robot. regarding the fact that amputation of a limb in human beings causes several mental, economical and social difficulties and problems, need to a substitute limb which has the most efficiency for the person after amputation is a vital need....

This paper discusses the damping measurements on cables with real-time controlled MR dampers that were performed on a laboratory scale single strand cable and on cables of the Sutong Bridge, China. The control approach aims at producing amplitude and frequency independent cable damping which is confirmed by the tests. The experimentally obtained cable damping in comparison to the theoretical va...

Cable-driven manipulators are traditionally designed for general performance objectives, such as maximisation of workspace. To take advantage of the reconfigurability of cable-driven mechanisms, the optimisation of cable-configurations for specific tasks is presented. Specifically, two types of task specific objectives are explored, the minimisation of cable forces over a desired trajectory and...

in this paper a performance analysis is presented for a cable-suspended parallel manipulator. experimental results from some first tests are presented and discussed to validate the theoretical calculation of load carrying capacity. the load-carrying capacity during a given trajectory is obtained. this computational technique is tested on a typical planar cable suspended manipulator. the experim...

The purpose of this study was to assess the removability and biological reactivity of an ultrahigh molecular weight polyethylene (UHMWPE) fiber cable as a new biomaterial for osteosynthesis. We used a pull-out test and an implantation test to analyze the performance of the UHMWPE fiber cable using a dog model, and compared its characteristics with those of a wire cable and a soft wire. In the p...
