Transient analysis of power loss density with time-harmonic electromagnetic waves in Debye media [PDF]

open access: yesRoyal Society Open Science, 2021
Due to the complex permittivity, it is difficult to directly clarify the transient mechanism between electromagnetic waves and Debye media. To overcome the above problem, the temporal relationship between the electromagnetic waves and permittivity is ...

Transient analysis of the Erlang A model [PDF]

open access: yesMathematical Methods of Operations Research, 2015
We consider the Erlang A model, or $M/M/m+M$ queue, with Poisson arrivals, exponential service times, and $m$ parallel servers, and the property that waiting customers abandon the queue after an exponential time. The queue length process is in this case a birth-death process, for which we obtain explicit expressions for the Laplace transforms of the ...

Thermal characteristics of Li‐ion battery based on phase change material‐aluminum plate‐fin composite heat dissipation

open access: yesEnergy Science & Engineering, 2023
A reliable battery thermal management system (BTMS) not only can effectively decrease the maximum temperature but also maintain the temperature uniformity of the lithium‐ion (Li‐ion) battery after grouping.

Modal Coupling in Presence of Dry Friction

open access: yesMachines, 2018
In this paper, we analyze the behavior of a single pad system in the presence of dry friction. The goal is to investigate the path that leads a stable mechanical system to unstable behavior.

Feedback Control Strategy for Transient Stability Application

open access: yesEnergies, 2022
Power systems are subjected to a wide range of disturbances during daily operations. Severe disturbances, such as a loss of a large generator, a three-phase bolted fault on a generator bus, or a loss of a transmission line, can lead to the loss of ...
