Computation Over Gaussian Networks With Orthogonal Components [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
Function computation of arbitrarily correlated discrete sources over Gaussian networks with orthogonal components is studied. Two classes of functions are considered: the arithmetic sum function and the type function.

Evaluation of orthogonal strain components in friction extrusion

open access: yesJournal of Materials Research and Technology, 2021
Friction extrusion is a thermomechanical process that combines conventional extrusion with the action of a rotating die. The plastic deformation of the material being sheared and extruded is the primary source of process heat and it produces strain ...

Symmetrical Components Digital Filters for Microprocessor-Based Protection Input Signals

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2023
In microprocessor protections, measuring bodies are used that react to individual symmetrical components of signals or a combination of them. This makes the corresponding protection devices more sensitive.
