In natural speech, a lot of interand intra-subject variation in the realisation of vowels is found. Perception experiments show that listeners can discriminate speaker-independent levels of vowel reduction. The question is whether all speakers used the same acoustic cues for signalling reduction levels. The acoustic realisation of reduction levels of the vowels [u:], [i:], and [a:] of three spe...

An automated system is used for fast human face recognition. The 2DFLD algorithm is tested on the various databases. PCA algorithm is tested on various databases. As the face system is totally nonintrusive, existing security of face recognition system are more effective without bothering the user in any way. The 2DFLD approach is compared with the standard PCA. The 2DFLD is used for recognizing...

Logistic regression is employed to search the optimal combination of multiple markers that can discriminate ovarian cancers from benign by Luminex assay test of the patient sera. To verify the selection performance, three other classification methods were also tested including t-test, genetic algorithm, and random forest. The chosen combinations from each of the four methods were evaluated agai...

In this work we explore the capability of audiovisual parameters (such as fundamental frequency, rhythm, head motion or facial expressions) to discriminate among different dramatic attitudes. We extract the audiovisual parameters from an acted corpus of attitudes and structure them as frame, syllable, and sentence-level features. Using Linear Discriminant Analysis classifiers, we show that sent...

The major compounds in honey are carbohydrates such as monosaccharides and disaccharides. The same compounds are found in cane-sugar concentrates. Unfortunately when sugar concentrate is added to honey, laboratory assessments are found to be ineffective in detecting this adulteration. Unlike tracing heavy metals in honey, sugar adulterated honey is much trickier and harder to detect, and tradit...

In this article, we propose a unified approach to estimating and modeling univariate time series. The approach applies to both linear and nonlinear time series models and can be used to discriminate non-nested nonlinear models. For example, it can discriminate between threshold autoregressive and bilinear models or between autoregressive and moving average models. It can also be used to estimat...

background: knowledge is limited concerning the role of temperament and character factors on schizophrenia. recent studies suggest that dimensions of temperament and character influence symptoms and functions in schizophrenia.  the purpose of this study was to determine the relationship between temperament and character with positive and negative symptoms in patients with schizophrenia. methods...
