A Comprehensive VSM Control Strategy Designed for Unbalanced Grids
Energies, 2019 A virtual synchronous machine (VSM) is a converter which, compared to other types of converters, has more friendly interactions with the power grid because it is able to simulate the external characteristics of a synchronous machine, which can provide ...

Shotgun metagenomic sequencing in culture negative microbial keratitis
European Journal of Ophthalmology, 2023 Purpose To evaluate the microbiota of culture negative Corneal Impression Membrane (CIM) microbial keratitis samples with the use of shotgun metagenomics analysis. Methods DNA of microbial keratitis samples were collected with CIM and extracted using the MasterPure™ Complete DNA and RNA Purification Kit (Epicentre).

Control of DFIG based wind generation systems under unbalanced network supply [PDF]
, 2007 This paper develops a dynamic model and control scheme for DFIG systems to improve the performance and stability under unbalanced grid conditions. A dynamic DFIG model containing the positive and negative sequence components is presented using stator ...

ON THE EXPONENTIAL INEQUALITY FOR NEGATIVE DEPENDENT SEQUENCE [PDF]
Communications of the Korean Mathematical Society, 2007 Summary: We show an exponential inequality for negatively associated and strictly stationary random variables replacing an uniform boundedness assumption by the existence of Laplace transforms. To obtain this result we use a truncation technique together with a block decomposition of the sums.

VSC control strategy for HVDC compensating negative sequence and decaying DC components
Energy Reports, 2023 This paper proposes a voltage source converter (VSC) control strategy for the high voltage direct current (HVDC) transmission systems compensating the negative sequence and decaying DC (DDC) components. The mathematical model of the grid fault current is

The Ricci flow in a class of solvmanifolds [PDF]
, 2012 In this paper, we study the Ricci flow of solvmanifolds whose Lie algebra has an abelian ideal of codimension one, by using the bracket flow. We prove that solutions to the Ricci flow are immortal, the omega-limit of bracket flow solutions is a single ...

Amended Informative Negative Whole Exome Sequencing Results [PDF]
, 2021 Abstract Background: Whole exome sequencing (WES) is widely used as a first-tier diagnostic test. The diagnostic yield for WES is estimated at approximately 50%, leaving the requesting clinician with 50% ambiguous or negative results in cases where the diseases-causing variants could not be identified.
