6～(th) International Conference on Spoken Language Processing

作者： Marilyn y.Chen Research Laboratory of Electronics MITCambridgeMA 02139

＜正＞The Lexical Access From Features （LAFF） project tries to model the representation and perception of speech by human listeners. The derivation of such a representation involves first finding certain acoustic landmarks. Based on the landmarks and the acoustic cues surrounding the landmarks, distinctive features of the speech segments may be decipherecd. The present study concentrates on the nasality module that attempts to detect the presence of an an underlying nasal consonant, which is almost always adjacent to a vowel. For an underlying nasal in English, the features |+voiced, +sonorant, +consonant, +nasal, -continuant| are specified. The features are then mapped into measurable acoustic properties. Normally, cues from three regions in the sound indicate the presence of a nasal consonant: （1） abrupt spectral change from the vowel to the nasal murmur. （2） vowel nasalization, and （3） nasal murmur. These cues are quantified by acoustic parameters whose values are combined to indicate the presence of a nasal. The nasality module thal has been developed is a sonorant landmark detector that greatly reduces false landmark detection and distinguishes nasals from laterals by incorporating additional nasal manner cues. The module also addresses cases where one or more of the three nasal cues is absent.

经济发展方式转变与自主创新——第十二届中国科学技术协会年会

作者： y.Martin Lo Department of Nutrition and Food Science University of MarylandCollege Park

To date,the published information on trans fatty acids (TFAs) in food products in China remains scarce and of questionable *** approaches to educate the consumers and to ensure proper labeling of TFAs are among the many urgent challenges the regulatory agencies in this rapidly growing country have to *** the present study,97 most popular,national brand food products on the Chinese market,including 6 cheeses,10 chocolates,10 crisps,chips,and fries,10 ice creams,15 margarines,10 pies and cakes,8 sauces and dressings,19 wafers and biscuits,and 9 Chinese-style snacks,were assayed to profile their fat content and fatty acid composition,particularly the *** highest level of TFAs,up to 30.9% of total fatty acids,were found in *** average TFAs contents in different product categories,ranging from high to low,were:pie and cake (12.07%),cheese (6.95%),margarine (5.09%),wafer and biscuit (4.35%),ice cream (2.67%),sauce and dressing (2.65%),crisps,chips,and fries (2.15%),chocolate (1.44%),and Chinese-style snacks (0.83%).One hundred percents of cheese contained TFAs,so did pie and cake,followed by crisps,chips,and fries (90%),sauce and dressing (88%),ice cream and margarine (80%),chocolate (60%),wafer and biscuit (53%),then Chinese-style snacks (33%).Profiling of key TFAs constituents could yield information characteristic to the types of partially hydrogenated oils employed,which is a critical step towards product reformulation in order to reduce or eliminate TFAs in the products.

Using the first principle method,we investigated the effect of tungsten carbide (WC) surface layers on hydrogen retention in *** results showed that C is not capable of efficiently capturing H atoms because of Coulombic repulsion between negatively charged C and H atoms in tungsten. Meanwhile,the repulsive force enhances the migration barrier for H to travel through WC layers

Photonics Asia 2004;Sensors and Imaging

作者： Osuk y.Kwon

These proceedings contain the papers presented at the Photonics Asia 2004 Advanced Sensors Systems and Applications conference, held 8-12 November 2004, in Beijing, China. This conference covered a number of key issues concerning recent progress in advanced sensors and their applications, in particular optical fiber sensors. After more than 20 years, worldwide research and development in the field of optical fiber sensors is still very active. This conference had many more papers submitted than that held two years ago. This strong growth may be due to significant reductions in the cost of most fiber optic components and the maturity of optical fiber sensors, such as fiber grating sensors and interferometric sensors.
