Large margin filtering for signal sequence labeling

, 2010
Signal Sequence Labeling consists in predicting a sequence of labels given an observed sequence of samples. A naive way is to filter the signal in order to reduce the noise and to apply a classification algorithm on the filtered samples.

On the formation and evolution of magnetic chemically peculiar stars in the solar neighborhood

, 2005
In order to put strict observational constraints on the evolutionary status of the magnetic chemically peculiar stars (CP2) of the upper main sequence, we have investigated a well established sample of galactic field CP2 objects within a radius of 200pc ...

Three‐phase isolated power transformer based novel structure for power distribution system and new theoretical/practical judgement criteria in detecting high‐impedance earth faults

IET Renewable Power Generation, 2023
Single phase‐earth faults are the most frequent faults likely to occur but hard to identify in distribution system, especially in a neutral un‐effectively grounded system.

A New Slot-PM Vernier Reluctance Machine With Enhanced Zero-Sequence Current Excitation for Electric Vehicle Propulsion

IEEE transactions on industrial electronics (1982. Print), 2020
This paper aims to propose a new Vernier reluctance machine (VRM), which integrates the advantages of a robust rotor structure, good torque density, and flexible flux control ability.

Zero product preserving bilinear operators acting in sequence spaces

Karpatsʹkì Matematičnì Publìkacìï, 2020
Consider a couple of sequence spaces and a product function $-$ a canonical bilinear map associated to the pointwise product $-$ acting in it. We analyze the class of "zero product preserving" bilinear operators associated with this product, that are ...

Subsequence Sums of Zero-sum-free Sequences [PDF]

The Electronic Journal of Combinatorics, 2009
Let $G$ be a finite abelian group, and let $S$ be a sequence of elements in $G$. Let $f(S)$ denote the number of elements in $G$ which can be expressed as the sum over a nonempty subsequence of $S$. In this paper, we slightly improve some results of Pixton on $f(S)$ and we show that for every zero-sum-free sequences $S$ over $G$ of length $|S|=\exp(G ...

High-impedance faulty feeder detection for cross-country faults in distribution networks based on zero-sequence active power regulation

International Journal of Electrical Power & Energy Systems
The weak characteristics of high-impedance faults and the complex attributes of cross-country faults make faulty feeder detection of cross-country high-impedance faults difficult in medium-voltage networks. This paper deduces the zero-sequence equivalent

Oscillating solutions for prescribed mean curvature equations: Euclidean and Lorentz-Minkowski cases

, 2018
This paper deals with the prescribed mean curvature equations both in the Euclidean case and in the Lorentz-Minkowski case in presence of a nonlinearity $g$ such that $g'(0)>0$.
