This paper presents the fallback understanding component of BBN's DELPHI NL sysystem. This component is invoked when the core DELPHI system is unable to understand an input. It incorporates both syntaxand frame-based fragment combination sub-components, in an attempt to provide a smoother path from accurate but fragile conventional parsers on the one hand to the robust but less accurate schema-...

      The fruit of Melia azedarach L. (Meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using GC/MS. Thirteen components representing 85.1% of the total extract were identified. The major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). The fruits’ extract had a LC50 of 5.5 ppm agai...

XAD-8 adsorption technique coupled with stepwise elution using pyrophosphate buffers with initial pH values of 3, 5, 7, 9, and 13 was developed to isolate Chinese standard fulvic acid (FA) and then separated the FA into five sub-fractions: FApH3, FApH5, FApH7, FApH9 and FApH13, respectively. Mass percentages of FApH3-FApH13 decreased from 42% to 2.5%, and the recovery ratios ranged from 99.0% t...

C4F7N is considered to be the most potential alternative gas for SF6. However, harmful decomposition by-products generated by discharge or overheating faults will pose threat safe operation and service life of insulated equipment (GIE). Herein, we investigated adsorption performance γ-Al2O3 on its products evaluate possibility using it as adsorbent exhaust treatment material. It found that demo...

A total of 245187 records of the first three lactations of 131126 Holstein cows in tropical conditions were used to estimate the genetic (co)variance components between age at calving and its respective milk productions. A multivariate analysis of six traits was performed. Heritability for age at calving (h2AC) and milk yield (h2MY) decrease from the ...

The present paper describes the linguistic components of a platform for building spoken language dialogue systems. The platform is being designed and implemented within the EU-language engineering project REWARD. The linguistic components mainly consist of a suite of general unification based natural language processing utilities and a window based Sub Grammar Design Tool which provides non-exp...

Reliability has vital significance to engineers and designers in a safety system. Consequently, failures free operation of components or sub-systems is of their key concern. To assess the reliability of such systems quantitatively, failure data of the components or sub-systems is essentially required. In general, such data is either not pre-recorded or present in linguistic form (good, bad etc)...
