Investigating synchronous and asynchronous class attendance as predictors of academic success in online education

open access: yesAustralasian Journal of Educational Technology, 2020
Learning is facilitated by participation and interaction and can be synchronously or asynchronously in online education. This study investigated the relationship between students’ academic success and online interaction and participation and explored ...

Case report: Spontaneous remission of synchronous endometrial and ovarian cancers following pregnancy

open access: yesFrontiers in Oncology, 2022
IntroductionEndometrial cancer is one of the most common malignancies affecting women. It is uncommonly diagnosed in young women, particularly in the absence of abnormal vaginal bleeding symptoms.Case presentationA 28-year-old woman was referred to our ...

Extension of the sun-synchronous Orbit [PDF]

open access: yes, 2010
Through careful consideration of the orbit perturbation force due to the oblate nature of the primary body a secular variation of the ascending node angle of a near-polar orbit can be induced without expulsion of propellant.

Modelling, Implementation, and Assessment of Virtual Synchronous Generator in Power Systems

open access: yesJournal of Modern Power Systems and Clean Energy, 2020
As more and more power electronic based generation units are integrated into power systems, the stable operation of power systems has been challenged due to the lack of system inertia. In order to solve this issue, the virtual synchronous generator (VSG),

Quantum Stochastic Synchronization [PDF]

open access: yesPhysical Review Letters, 2006
We study within the spin-boson dynamics the synchronization of quantum tunneling with an external periodic driving signal. As a main result we find that at a sufficiently large system-bath coupling strength (Kondo parameter a>1) the thermal noise plays a constructive role in yielding both a frequency and a phase synchronization in a symmetric two ...

A synchronous game for binary constraint systems

open access: yes, 2017
Recently, W. Slofstra proved that the set of quantum correlations is not closed. We prove that the set of synchronous quantum correlations is not closed, which implies his result, by giving an example of a synchronous game that has a perfect quantum ...

Restricting the Weak-Generative Capacity of Synchronous Tree-Adjoining Grammars [PDF]

open access: yes, 1994
The formalism of synchronous tree-adjoining grammars, a variant of standard tree-adjoining grammars (TAG), was intended to allow the use of TAGs for language transduction in addition to language specification.

Inertia Response Improvement in AC Microgrids: A Fuzzy-Based Virtual Synchronous Generator Control

open access: yesIEEE transactions on power electronics, 2020
The absence of rotational masses from synchronous generators in converter-interfaced microgrids leads to a lack of inertia. Consequently, the system exhibits steeper frequency variations and higher frequency nadir, which may degrade the dynamic ...
