Behavior of the PMD coefficient of optical links under influence of mechanical and thermal effects
This papers presents results on the variation of the PMD coefficient of optical links under influence of mechanical tests, such as tensile strength, bending and compression, and also during the application of a thermal ...
Dielectric behavior of XLPE aged under multi-stressing conditions
In this work fresh cables were laboratory aged under multi-stressing conditions at room temperature. Foils were peeled from cables, with approximately 150 ?m thickness, from the outer, middle and inner positions of the ...
p-Cable Trench Problem with Covering
We introduce the p-Cable Trench problem with Covering. In this problem, p primary servers (e.g., routers) are located and a set of secondary servers (e.g., extended range WiFi antennas) is connected to each of them, to ...
A Branch And Cut Method To Solve The P-Cable Trench Problem
The p-cable trench is a network design problem consisting in locating p facilities and connecting each client with a facility through a cable. Cables must lie in trenches. The objective minimizes cable length and trench ...
Properties of individual YBCO layers in a two-layered design for energy-efficient digital data cables
We are developing two-layered Yttrium Barium Copper Oxide (YBCO) thin film structures for energy efficient data links for superconducting electronics and present the results of their property measurements. High temperature ...
Electrical devices obtained from polymeric precursors process
Nowadays, many investments have been made in the area of superconductor materials, with the aim to improve their potential technological applications. Applications on the energy transport using cables, to get high resolution ...
