1 Introduction In a distant-talking environment, channel distortion drastically degrades speech recognition performance because of mismatches between the training and test environments. The current approaches focusing on robustness issues for automatic speech recognition (ASR) in noisy reverberant environments can be classified as speech enhancement, robust feature extraction, or model adaptati...

A one kb portion of the rpoS gene from Flexibacter chinensis was isolated by PCR, sequenced and compared to the rpoS gene of a variety of other organisms. The gene was found to be 98% similar to previously sequenced genes. Mutation of the rpoS gene with tri-parental mating produced strain JR101 and the growth rate of the mutant was compared with that of the wild-type. The mutant grew slower, an...

The Chicago cap-and-trade approach to regulating stationary source VOC emissions in the Chicago ozone non-attainment area is a pioneering program that could set a precedent for other urban areas troubled by high ozone concentrations. It holds out the promise of cost-effectiveness, innovation stimulation, and flexibility compared with traditional regulation. To appraise this program design and e...

Campylobacter jejuni has been reported as a major cause of bacterial food-borne enteritides in developed countries during the last decade. Despite its fastidious growth requirements, including low level of oxygen and high level of CO2, this pathogen is able to persist in the environment without permanent loss of its viability and virulence. As C. jejuni is not able to multiply outside a host, t...

The presence of pedestrians is definitory for street vitality. This study employs statistical and geospatial analyses to explore how built environment factors explain changes in “pedestrian flows” “stationary activities” on fifteen segments Shanghai, at a mesoscale. Detailed indicators were collected through field surveys, behavioral mappings, counting. Changes are distinguished from those acti...

In this paper, we present an architecture for presentation, access and exchange of information in a mobile computing environment. In the project MOVI, a new approach is developed which enables applications on mobile computers for exchange and visualization of multimedia objects with applications on stationary database servers via the

on the onset of triple-diffusive convection in a horizontal layer of nanofluid heated from below and salted from above and below is studied both analytically and numerically. the effects of thermophoresis and brownian diffusion parameters are also introduced through buongiorno model in the governing equations. by using linear stability analysis based on perturbation theory and applying normal m...

in this paper, we study projected non-stationary simultaneous it-erative reconstruction techniques (p-sirt). based on algorithmic op-erators, convergence result are adjusted with opial’s theorem. the advantages of p-sirt are demonstrated on examples taken from to-mographic imaging.

in this paper, we investigate the concept of topological stationary for locally compact semigroups. in [4], t. mitchell proved that a semigroup s is right stationary if and only if m(s) has a left invariant mean. in this case, the set of values ?(f) where ? runs over all left invariant means on m(s) coincides with the set of constants in the weak* closed convex hull of right translates of f. th...
