چکیده
•Utterances were annotated according to three levels: – Neutral (level 1) : unstress, normal or neutral speech, happy, relax; – Medium (level 2): stress, speech is nervous, there is tension in the voice, more speed, there are hesitations; – Higher (level 3): high stress, there are shouts, anger, despair.

Numerical/Experimental Analysis of the Deformation of Tubes under Concentrated Load
Distortion and deformation of tubes during machining operations are very important. In this study, a tube used in magnetic drum separator under concentrated load (machining load) is considered. Using finite element simulation, deformities and their dependence on parameters such as the thickness of the tube and the place of concentrated force are observed and predicted. To compare and confirm th...

متن کاملThe analysis of a Beam Made of Physical Nonlinear Material on Elastic Foundation Under a Harmonic Load
ABSTRACT: A prismatic beam made of a behaviorally nonlinear material situated on nonlinear elastic foundation is analyzed under a moving harmonic load moving with a known velocity. The vibration equation of motion is derived using Hamilton principle and Euler Lagrange equation. The amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam can be calculat...
متن کاملA FSDT model for vibration analysis of Nano rectangular FG plate based on Modified Couple Stress Theory under moving load
In present paper, vibration of Nano FGM plate based on modified couple stress and First Order Shear Deformation Theories (FSDT) under moving load has been developed. Basic equations and linear strains are introduced by first order shear deformation theory and Mori Tanaka’s model is used for the plate. The module of elasticity and density are assumed to vary only through thickness of plate. Gove...
متن کاملOn the use of Bhattacharyya based GMM distance and neural net features for identification of cognitive load levels
This paper presents a method for detecting cognitive load levels from speech. When speech is modulated by different levels of cognitive load, acoustic characteristics of speech change. In this paper, we measure acoustic distance of a stressed utterance from the baseline stress free speech using GMM-SVM kernel with Bhattacharyya based GMM distance. In addition, it is believed that airflow struct...
