Transient analysis of manufacturing systems performance [PDF]

open access: yesIEEE Transactions on Robotics and Automation, 1994
We present several situations in manufacturing systems where transient analysis is very important. Manufacturing systems and models in which such situations arise include: systems with failure states and deadlocks, unstable queueing systems, and systems with fluctuating or nonstationary workloads.

TRANSIENT REGIMES OF THE THREE-PHASE POWER TRANSFORMERS [PDF]

open access: yesCarpathian Journal of Electrical Engineering, 2015
The transient regimes of a three-phase power transformer will be studied in this paper. The transient currents in the windings will be determined both analytically and by finite elements method (FEM).

Numerical Calculation of Overhead Power Lines Dynamics

open access: yesJournal of Mechanical Engineering, 2016
This paper contains results of transient analysis of airflow around the ACSR power line cross-section in unsymmetric multi-span. The forces applied to the power line are obtained from CFD simulations, where the wind induced vibration is studied.

Transient Analysis and Execution-Level Power Tracking Control of the Concentrating Solar Thermal Power Plant

open access: yesEnergies, 2019
Concentrating solar power (CSP) is a promising technology for exploiting solar energy. A major advantage of CSP plants lies in their capability of integrating with thermal energy storage; hence, they can have a similar operability to that of fossil-fired

Analysis of Transients [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1939
A discussion is given of the frequency distribution of several types of non-periodic phenomena. The method of spectral analysis employing the Fourier integral is applied to a sine wave of short duration and it is shown that when the envelope is square-topped, noise components are present extending far to each side of the central frequency band, whereas
