A detailed introduction to variogram analysis of reflectance data is provided, and variogram parameters (nugget, sill, and range values) were examined as possible indicators of abiotic (irrigation regime) and biotic (spider mite infestation) stressors. Reflectance data was acquired from 2 maize hybrids (Zea mays L.) at multiple time points in 2 data sets (229 hyperspectral images), and data fro...

Since fluid-structure interaction within the finite-element method is state of the art in many engineering fields, this method is used in voice analysis. A quasi two-dimensional model of the vocal folds including the ventricular folds is presented. First results of self-sustained vocal fold oscillation are presented and possibilities as well as limitations are discussed.

The objective of this study is to numerically investigate the temperature and heat transfer characteristics of the voice coil for a woofer with and without bobbins using the thermal equivalent heat conduction models. The temperature and heat transfer characteristics of the main components of the woofer were analyzed with input powers ranging from 5 W to 60 W. The numerical results of the voice ...

The present study explored the sensitivity to stress patterns of sixty-four ninthgraders learning to speak and read in Korean as a first language (L1) and English as a second language (L2) concurrently. Students’ productive stress processing abilities were assessed in reading Korean real words, English unfamiliar real words, and English pseudowords. Results unveiled that the Korean-speaking Eng...

This paper describes a study of a protocol and a system for automatic detection and status tracking of early-stage dementia and Mild Cognitive Impairment (MCI), from speech and voice recordings. The research has been performed in the scope of the EU FP7 Dem@Care project. We describe the speech and voice recording protocol, different families of vocal features as derived from the recorded data, ...

The dramatic impact of neurological degenerative pathologies in life quality is a growing concern. It is well known that many neurological diseases leave a fingerprint in voice and speech production. Many techniques have been designed for the detection, diagnose and monitoring the neurological disease. Most of them are costly or difficult to extend to primary attention medical services. Through...

We examined the impact of job stress and physical exhaustion on the physiological and subjective components of emotional responding during marital interactions between 19 male police officers and their spouses. Couples completed 3D-day stress diaries and participated in 4 weekly laboratory interaction sessions. During interactions on days of greater stress, both spouses were more physiologicall...

We tested the ability of humans and machines (data mining techniques) to assign stress to Slovene words. This is a challenging comparison for machines since humans accomplish the task outstandingly even on unknown words without any context. The goal of finding good machine-made models for stress assignment was set by applying new methods and by making use of a known theory about rules for stres...

English lexical stress is multidimensional in nature and acoustically related to combination of fundamental frequency (F0), duration, intensity and vowel quality. Errors in any or all of these correlates could interfere with perception of the stress contrast, but it is unknown which correlates are most difficult for Bengali speakers to acquire. This study compares the use of these correlates in...
