The Knowledge Base Population (KBP) track at the Text Analysis Conference 2010 marks the second year of this important information extraction evaluation. This paper describes the design and implementation of LCC’s systems which participated in the tasks of Entity Linking, Slot Filling, and the new task of Surprise Slot Filling. For the entity linking task, our top score was achieved through a r...

This paper describes our participation in the SemEval-2016 task 5, Aspect Based Sentiment Analysis (ABSA). We participated in two slots in the sentence level ABSA (Subtask 1) namely: aspect category extraction (Slot 1) and sentiment polarity extraction (Slot 3) in English Restaurants and Laptops reviews. For Slot 1, we applied different models for each domain. In the restaurants domain, we used...

This paper presents the efficiency improvement of a pole-changing vernier machine (PCVM) by considering residual magnetic flux density (Br) low coercivity force (LCF) permanent magnets (PMs). The PCVM operates in two modes: (VM) mode and magnet synchronous (PMSM) mode, achieved through pole-changing. Pole-changing involves reversing direction LCF PM to alter number rotor pole pairs. By changing...

A statistical multiplexer with a finite number of independent, not necessarily identical, bursty traffic sources is considered in this paper. Each source stochastically alternates between on-periods, during which it generates one cell per slot, and off-periods, during which no cells are generated. The on-periods and the off-periods are assumed to be independent, but are allowed to have general ...

Permanent magnet synchronous machines with fractional slot stator windings using the tooth coil technology require detailed investigations on the electromagnetic parameters due to a very low number of slots per pole and phase. Finite element analyses can provide many results but a subsequent application of the frozen permeabilities method allows for a more detailed discussion of effects caused ...

In this article, performance of 70 W, 350 rpm, axial-field and radial-field permanent magnet brushless dc motors is compared using computer aided design sCADd and finite element sFEd methods. The design variables like number of poles, slots per pole per phase, airgap length, airgap flux density, slot electric loading, stator flux density, and the permanent magnet material are changed one at a t...

The rotor configuration of the brushless doubly fed induction generator (BDFIG) plays an important role in its performance. In order to make the magnetomotive force (MMF) space vector in one set rotor windings to couple both magnetic fields with different pole-pair and have low resistance and inductance, this paper presents a novel wound rotor type for BDFIG with low space harmonic contents. In...

A pediatric ventricular assist device (VAD) using an ultra-compact self-bearing motor, in which a 4-pole levitated impeller is magnetically supported and rotated by two identical 6-slot motor stators has been developed. The outer diameter height of the are 22 mm 35 mm, respectively. previously developed uses electromagnets that integrate all windings for magnetic suspension rotation control. Ea...
