Speech Emotion Recognition (SER) is an important part of speech-based Human-Computer Interface (HCI) applications. Previous SER methods rely on the extraction of features and training an appropriate classifier. However, most of those features can be affected by emotionally irrelevant factors such as gender, speaking styles and environment. Here, an SER method has been proposed based on a concat...

Multi-code (MC) access and Variable-Spreading-Length (YSL) access are two widely applied realizations for multidata-rate services in direct-sequence code-division multiple-access (DSEDM) systems. We study the behavior of these two multi-rate realizations operating in multi-path fading channels. Bounds of minimum probability of error based on maximum-likelihood sequence detection are developed f...

In this study the influence of azelaic acid (AZA) 20% cream on the sebum excretion rate (SER) of 80 volunteers having mild to moderate acne vulgaris was demonstrated. Absorbent paper and Sebutape were used to collect the sebum and quantification was carried out by direct gravimetric method. It was shown that topical application of AZA creams could reduce the SER and number of acneic lesions...
