This paper addresses the problem of learning multiple spoken language understanding (SLU) tasks that have overlapping sets of slots. In such a scenario, it is possible to achieve better slot filling performance by learning multiple tasks simultaneously, as opposed to learning them independently. We focus on presenting a number of simple multi-task learning algorithms for slot filling systems ba...

Effects of magnetic saturation on various equivalent circuit models of an induction motor are studied. The parameters of 2.2-kW and 37-kW motors with closed rotor slots are analyzed using finite element computations. Both skewed and unskewed rotor slots are studied. The magnetizing inductance not only depends on the main flux, but is also dependent on the rotor current, especially if the rotor ...

Schemata are expressions that are fixed except for slots available for novel words (I'm not a ______ person). Our goals were to quantify speakers' knowledge, examine semantic flexibility in open slots, and compare performance data in two generations of speakers using cloze procedures in formulaic expressions, schemata open slots, fixed portions of schemata, and novel sentences. Fewer unique wor...

We consider the task of designing a truthful auction mechanism for CPU time scheduling problem. There are m commodities (time slots) T = {t1, t2, . . . , tm} for n buyers I = {1, 2, . . . , n}. Each buyer requires a number of time slots si for its task. The valuation function of buyer i for a bundle of time slots Ti is vi(Ti) = wi(m− t), where t is the last time slot in Ti and |Ti| = si. The ut...

In busy airports, too many departing flights take off out of the time slot required by the Central Flow Management Unit (CFMU). During ground traffic peaks, taxi out times and runway queuing delays increase, and it seems very hard and maybe unfeasible for ground controllers to organise properly the traffic so that aircraft take off at their scheduled time. In a first part, this paper shows how ...

We address the problem of automatically acquiring case frame patterns (selectional patterns) from large corpus data. In particular, we propose a method of learning dependencies between case frame slots. We view the problem of learning case frame patterns as that of learning multi-dimensional discrete joint distributions, where random variables represent case slots. We then formalize the depende...

In this pare, a wideband three-order bandpass filter (BPF) is proposed. The proposed wideband filter is designed using the substrate integrated waveguide (SIW) structure by loading T-shape slots. A BPF with two resonators is formed by etching T-shape slots with different size on the top metal plane of the SIW structure. The filter is investigated with the theory of coupled resonator circuits. T...

This system is the result of our previous work on the subject of school timetabling. It was designed to respond mainly to Portuguese schools from various educational levels. It consists of three main blocks; a graphical user interface; an automatic scheduler and a relational database. This system is now in use by more than 100 schools in Portugal with significant success (http://www.fmaismais.p...

In this paper, two types of dual permanent magnet (PM) machines, i.e., stator slot dual-PM (SSDPM) machine and split-tooth (STDPM) machine, are investigated compared. Both machines have consequent pole structure with Halbach array PMs. Their difference lies in the position PM. The SSDPM has PMs slots, while STDPM between split teeth. Torque characteristics, average torques torque ripples, diffe...

EM1 from slots and apertures resulting from coupling of interior sources through enclosure cavity modes in a Sun S-1000 workstation was investigated. The excitation of a specially designed rectangular enclosure with a slot was also studied experimentally and with finite-difference time-domain (FDTD) simulations. The radiated power results for both the S-1000 and simple rectangular enclosure ind...
