Very little previous research has addressed the prosodic characteristics of third party complaints. This paper discusses an utterance and word level intonational analysis of this speech act in four speakers of Mexican Spanish. The effect of social distance/ power relationships was incorporated into the study by creating an experimental data elicitation task in which participants addressed identical complaints to a friend, as well as a boss, based on a series of hypothetical contexts. Major global findings revealed that all speakers significantly increased their fundamental frequency (F0) mean when directing their complaints to friends, however, only two speakers significantly expanded their F0 range in the same circumstance. Locally, peaks and valleys were manifested at significantly higher levels across the board when addressing friends. Finally, while speakers produced complaint contours of similar overall shape regardless of hearer, individual variation was present in the form of circumflex versus suppressed utterance-final F0 configurations. Overall, the relatively small data set initiated preliminary thoughts on the application of both cross-linguistic and language- and dialect-specific intonational concepts to complaints while also emphasizing the importance of relationships between interlocutors for future studies.

Small data set approach is used for the estimation of Largest Lyapunov Exponent (LLE). Primarily, the mean period drawback of Small data set was corrected. On this base, the LLEs of daily qualified rate time series of HZ, an electronic manufacturing enterprise, were estimated and all positive LLEs were taken which indicate that this time series is a chaotic time series and the corresponding produce process is a chaotic process. The variance of the LLEs revealed the struggle between the divergence nature of quality system and quality control effort. LLEs showed sharp increase in getting worse quality level coincide with the company shutdown. HZ’s daily qualified rate, a chaotic time series, shows us the predictable nature of quality system in a short-run.

The goals of this study are the suggestion of a better classification method for detecting stressed states based on raw electrocardiogram (ECG) data and a method for training a deep neural network (DNN) with a smaller data set. We suggest an end-to-end architecture to detect stress using raw ECGs. The architecture consists of successive stages that contain convolutional layers. In this study, two kinds of data sets are used to train and validate the model: A driving data set and a mental arithmetic data set, which smaller than the driving data set. We apply a transfer learning method to train a model with a small data set. The proposed model shows better performance, based on receiver operating curves, than conventional methods. Compared with other DNN methods using raw ECGs, the proposed model improves the accuracy from 87.39% to 90.19%. The transfer learning method improves accuracy by 12.01% and 10.06% when 10 s and 60 s of ECG signals, respectively, are used in the model. In conclusion, our model outperforms previous models using raw ECGs from a small data set and, so, we believe that our model can significantly contribute to mobile healthcare for stress management in daily life.
