At the leading edge of healing embryonic epithelium, cables of actin filaments appear to extend from cell to cell, forming a ring around the wound circumference. It has been hypothesized that this actin filament cable functions as a contractile 'purse string' to facilitate wound closure. We have observed this cable in large, circular healing epithelial wounds in corneas of adult mice. To elucid...

Cable winding is an alternative technology to create stator windings in large electrical machines. Today such cable winding is performed manually, which is very repetitive, time-consuming and therefore also expensive. This paper presents the design, function and control system of a developed cable feeder tool for robotized stator cable winding. The presented tool was able to catch a cable insid...

Introduction. To achieve a functional atraumatic cochlear implantation, intracochlear pressure changes during the procedure should be minimized. Postinsertional cable movements are assumed to induce intracochlear pressure changes. The aim of this study was to observe intracochlear pressure changes due to postinsertional cable movements. Materials and Methods. Intracochlear pressure changes were...

In this paper, a bolt feeding device and assembly system are designed manufactured. The includes: incoming parts, including material channel, which is used to accommodate bolts; the part includes silo first power part. equipped with receiving hole can be opposite channel. bolts in channel moved hole. push hole, so that head of set axial clearance. above scheme facilitate stable pickup by downst...

In order to solve the coupling error problem of smart bolt, model piezoelectric thin film sensor and bolt is established by using constitutive equation. The size parameters ZnO are simulated analyzed finite element method Comsol software M10×1.5 prepared on bolt. First, sensors different materials compared, then shape, thickness simulated; electrode material simulated. simulation results show t...

The available EMTP-type programs have dedicated support routines (Cable Constants) for calculating an electric representation of cable systems in terms of a series impedance matrix Z and a shunt admittance matrix Y, based on cable data defined by geometry and material properties. Z and Y are then used as the basic input for the various cable models applied in time domain transient simulations. ...

Effective competition for local monopoly cable systems would seem to offer a natural solution to nagging problems widely attributed to the cable industry, such as high prices and poor service. In regulatory and legislative proceedings leading up to the Cable Television Consumer Protection and Competition Act of 1992,(note 1) however, potential or existing competitors to local cable systems comp...

Cable interference in cable-driven mechanisms (CDM) is a major challenge in their applications. The wrench closure workspace (WCW) in a fully constrained mechanism may not be realized unless cable interference is considered. This paper classifies all possible types of cable interferences for planar cable-driven mechanisms and presents an analytical solution to find the boundaries of the constan...

I measure the benefit to households of the 1992 Cable Act in light of strategic responses by cable systems to the regulations mandated by the act. A discrete-choice differentiatedproduct model of household demand for all offered cable television services forms the basis of the analysis. Aggregation over households and service combinations to the level of the data permits estimation on a cross-s...
