This paper presents the electromagnetic Finite Element Analysis (FEA) of a novel chip-to-chip interconnect for use in System-in-Package (SiP) applications. An on-chip coplanar transmission line is transitioned to an off-chip coaxial cable using an etched trench on Silicon. This approach to die-to-die signaling has inherent advantages over traditional wire bonding that include matched impedance,...
Cable ploughing is an important technique for burying and protecting offshore cables. The ability to predict the required tow force plough performance essential allow vessel selection project programming. Existing models require calibration against full-scale field testing determine empirical parameters, a requirement that may hinder their use. In this study factors controlling resistance were ...
The aging of insulating materials can be estimated by an electrical breakdown occurring in electrical components so that the relationship between lifetime, failure probability and reliability of electrical components may be studied using the life models in high voltage cables networks. In last decades with attention to higher features as electrical, thermal, mechanical characteristic, widely cr...
This document describes an optimization problem of cable cross section of a cable stayed bridge considering constraints of cable stress and deck displacement. Since the bridge is still in study phase, the geometry and the mechanical characteristics are subjected to changes. In order to avoid creating different structural models, a program was produced to construct a model from geometrical and m...
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...
Power cable is a piece of major transmission equipment, and its operating temperature as factor determines whether the system can operate safely reliably current-carrying capacity. Therefore, it great significance to master real-time distribution power core. During aging insulation, temperature, factor, directly rate. One basic parameters on ampacity. If ampacity high, will be overloaded. In th...
The paper deals with a numerical analusis for the seismic response of reinforced concrete structures containing cable elements. The cable behaviour is considered as nonconvex and nonmonotone one and is described by generalized subdifferential relations including loosening, elastoplastic fracturing etc. effects. The problem is treated incrementally by double discretization: in space by finite el...
the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...
Previous studies of the cable television industry have focused on the effects of deregulation and competition on cable service prices. These studies use either the "most popular" tier or the "lowest-priced" tier when comparing prices of different cable systems. However, these tiers often represent a different type of cable service so that previous empirical results based on the assumption that ...
