Numerical Modeling of Space–Time Characteristics of Plasma Initialization in a Secondary Arc
Energies, 2019 A numerical model based on the finite element simulation software COMSOL was developed to investigate the secondary arc that can limit the success of single-phase auto-reclosure solutions to the single-phase-to-ground fault.

Fast Arc-Annotated Subsequence Matching in Linear Space [PDF]
, 2010 An arc-annotated string is a string of characters, called bases, augmented with a set of pairs, called arcs, each connecting two bases. Given arc-annotated strings $P$ and $Q$ the arc-preserving subsequence problem is to determine if $P$ can be obtained ...

Human Pancreas GH-Releasing Factor Analog Restores High-Amplitude GH Pulses in CNS Lesion-Induced GH Deficiency [PDF]
, 1983 Lesions of the ventromedial-arcuate (VMH-ARC) region of the hypothalamus result in impaired growth accompanied by a marked suppression in spontaneous GH secretory bursts. We studied the effects of an analog of the recently characterized human pancreas GH-

Secondary Arc Extinction in Extra High Voltage Systems Using Grounding Switches
Diyala Journal of Engineering Sciences, 2014 Long Extra High Voltage (EHV) transmission systems tend to bring a pronounced state of secondary arcing. Therefore, an essential pre-requisite for single-phase-switching application, is the possibility and speed of secondary arc final extinction during ...

On the combinatorics of sparsification [PDF]
, 2012 Background: We study the sparsification of dynamic programming folding algorithms of RNA structures. Sparsification applies to the mfe-folding of RNA structures and can lead to a significant reduction of time complexity.

Modeling Study of the Secondary Arc With Stochastic Initial Positions Caused by the Primary Arc [PDF]
IEEE Transactions on Plasma Science, 2015 In the conversion process from primary arc to secondary arc, there exists stochasticness phenomenon of the initial positions of secondary arc. However, the present simulation results of the arcing time with the arc chain model are constant, which is not consistent with the test results.

On-sky wide field adaptive optics correction using multiple laser guide stars at the MMT [PDF]
, 2008 We describe results from the first astronomical adaptive optics system to use multiple laser guide stars, located at the 6.5-m MMT telescope in Arizona. Its initial operational mode, ground-layer adaptive optics (GLAO), provides uniform stellar wavefront
