extended abstract introduction the present paper examines the ecological footprint of kermanshah as the 9th largest city of iran. it also tries to answer the following question: dose the ecological environment of kermanshah support the basic needs of it's population? and are the biological systems of kermanshah able to answer all socio- economic questions related to different activities o...

In electric power systems, power cable operation under normal conditions is very important. Various cable faults will happen in practical applications. Recognizing the cable faults correctly and in a timely manner is crucial. In this paper we propose a method that an annealed chaotic competitive learning network recognizes power cable types. The result shows a good performance using the support...

A power cable is widely used for power supply in power distributing networks and power transmission lines. Due to limitations in the production, delivery and setting up power cables, they are produced and delivered in several separate lengths. Cable itself, consists of two cable terminations and arbitrary number of cable joints, depending on the cable route length. Electrical stress control is ...

The full set of TCS measurements performed during 2000–2002 on conductor 1A of the ITER Central Solenoid Model Coil (CSMC) of the International Thermonuclear Experimental Reactor (ITER) is analysed with the extensively validated M&M code. Under the assumptions of uniform strand properties and uniform current distribution among strands, the performance of this ‘‘average’’ strand in the cable is ...

The cable tower of Liede Bridge is a double-column curved-lever arched-beam portal framed structure. Being novel and unique in structure, its cable tower differs in complexity from traditional ones. This paper analyzes the ultimate load capacity of cable tower by adopting the finite element calculations and model tests which indicate that constitutive relations applied here give a better simula...

Pulsating and explosive time profiles of mm-wave solar bursts observed at Metsähovi are examined in terms of the energy release in a single current-carrying loop. We suppose that the electric current in the loop is driven by photospheric convective flows. The flare occurs due to flute instability provoking the penetration of partially ionized plasma from the chromosphere or prominence into the ...

Transmission lines are used to transmit energy such as acoustic or electromagnetic waves or bulk of electrical energy from one place to another, and co-axial shielded cable of them. Other means of transportation are two-wires (twisted pair cable and un-twisted pair cable). All such transmission lines are prone to noise coupling from ambient environment, for example, noise from capacitive coupli...

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. ...
