This paper describes an Arc add-in for the delta method for regression models. The method works for linear models, generalized linear models, nonlinear models and also for generalized nonlinear models. The delta method is a procedure for finding estimates and approximate standard errors of arbitrary functions of normally distributed random variables. As implemented in Arc, the delta method is u...

Plasma enhanced techniques are widely used for synthesis of carbon nanostructures. The primary focus of this paper is to summarize recent experimental and theoretical advances in understanding of single-wall carbon nanotube SWNT synthesis mechanism in arcs, and to describe methods of controlling arc plasma parameters. Fundamental issues related to synthesis of SWNTs, which is a relationship bet...

A differential precoding scheme for random linear network coding is proposed and assessed. We derive the sets of parameters for which the use of higher rates and smaller packet lengths is possible when compared to the standard approach using a lifting construction. It is demonstrated how rank-metric codes may be used for this differential coding approach in order to improve performance and to d...

This paper presents a new application of a fractional order control system which controls the input energy to a three phase electric arc furnace. Graphite electrodes are used to convert electrical energy into heat via phase electric arcs. Constant arc length is desirable as it implies steady energy transfer from the graphite electrodes to the metallic charge in the furnace bath. With the charge...

The interaction between a fault arc and power system has a big influence on the successful reclosing of a faulted system and hence evaluation of this interaction is very important. This paper mainly focuses on a proposed technique of simplified arc model for evaluation of single phase reclosing scheme for extra high voltage transmission system. Both primary and secondary arcs behavior have been...

Universal Dependency (UD) annotations, despite their usefulness for cross-lingual tasks and semantic applications, are not optimised for statistical parsing. In the paper, we ask what exactly causes the decrease in parsing accuracy when training a parser on UD-style annotations and whether the effect is similarly strong for all languages. We conduct a series of experiments where we systematical...

An arc in a tournament T with n ≥ 3 vertices is called pancyclic if it belongs to a cycle of length l for all 3 ≤ l ≤ n. We call a vertex u of T an out-arc pancyclic vertex of T if each out-arc of u is pancyclic in T . Yao, Guo and Zhang [Discrete Appl. Math. 99 (2000), 245–249] proved that every strong tournament contains at least one out-arc pancyclic vertex, and they gave an infinite class o...

An adaptive control based on fuzzy logic has been implemented for Gas Tungsten Arc Welding (GTAW). This adaptive controller eliminates the problems frequently experienced with traditional Automatic Voltage Control (AVC) systems, which do not adequately perform for all operational conditions because of the non-linear relationship between the arc voltage, current and arc length. This paper examin...

Many applications of geometry processing and computer vision rely on geometric properties of curves, particularly their curvature. Several methods have already been proposed to estimate the curvature of a planar curve, most of them for curves in digital spaces. This work proposes a new scheme for estimating curvature and torsion of planar and spatial curves, based on weighted least–squares fitt...
