Calculation of crosstalks in multiple-conductor cables
The rigorous method of calculations of characteristics of two-wire lines (twisted pairs) inside the metal armor and of a mutual coupling between lines is considered. It is shown that the mutual coupling between lines in multiple-conductor cables results in appearance of electromagnetic interferences (crosstalks) in communication channels. The voltages values (interferences) across the impedances placed at the beginning and the end of the adjacent line at the given power in the main line are determined.
Study on electromagnetic interference of multiconductor twisted‐pair wire circuit: The case of two‐cored twisted‐pair wires
The purpose of this study is to clarify the mechanism of electromagnetic interference of a multiconductor twisted-pair wire circuit. In this study, two-cored (n = 2) twisted-pair wire is treated and a simple model of twisted-pair wire is proposed. Using the proposed twisted-pair wire model, crosstalk between twisted-pair wires is predicted. Based on the calculated and experimental results it is shown that both inductive and capacitive coupling must be taken into account in order to accurately predict the crosstalk between twisted-pair wires. For inductively coupled induced voltages, the same technique that is used for the parallel wires has been used; but a new technique is proposed for calculation of capacitively coupled voltages. © 1997 Scripta Technica, Inc.

A new stochastic factor model: General explicit solutions
We present a new stochastic factor model. In doing so, we provide general, explicit solutions to the portfolio optimization problem.
