Influence of time constants of frequency regulators on the amplitude of power exchange fluctuations in autonomous diesel power plants

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2020
The application of autonomous electrical complexes with parallel diesel generator sets based on synchronous generators is considered. The problem of the existence of exchange power fluctuations in such technical systems is described. A mathematical model

Experimental and Quasi-Experimental Research in CSCL

open access: yes, 2021
(Quasi-)experimental designs play an important role in CSCL research. By actively manipulating one or several independent variables while keeping other influencing factors constant and through the use of randomization, they allow to determine the causal effects of such independent variables on one or more dependent variable(s) that may be of interest ...

Is experimental research passé [PDF]

open access: yesAdvances in Health Sciences Education, 2010
In perusing the contents of this issue, I discovered that, once again, the majority of the papers are not experimental. There are several qualitative studies—of teachers’ attitudes to student feedback, reflective learning for continuing education, residents’ perceptions of outpatient teaching, and assessment expert’s view of the framework for ...

Faraday's “Experimental Researches” [PDF]

open access: yesNature, 1878
MR. SILVANUS P. THOMPSON, of Bristol, has made, in NATURE (vol. xvii. p. 304) an inexplicable attack upon my issue of Faraday's “Experimental Researches in Electricity”, 3 vols. 8vo. 1839–55, unwarranted by logic or facts.

Extracorporeal circulation models in small animals: beyond the limits of preclinical research [PDF]

open access: yesAcute and Critical Care, 2023
Extracorporeal membrane oxygenation (ECMO) use has remarkably increased in recent years. Although ECMO has become essential for patients with refractory cardiac and respiratory failure, extracorporeal circulation (ECC) is associated with significant ...
