this paper aims to explore some acoustic properties (i.e. duration and pitch amplitude of speech) associated with three different emotions: anger, sadness and joy against neutrality as a reference point, all being intentionally expressed by six persian speakers. the primary purpose of this study is to find out if there is any correspondence between the given emotions and prosody patterning in p...

The tilt intonation model facilitates automatic analysis and synthesis of intonation. The analysis algorithm detects intonational events in F0 contours and parameterises them in terms of the continuously varying Tilt parameters. We describe the analysis system and give results for speaker independent spontaneous dialogue speech. We then describe a synthesis algorithm which can generate F0 conto...

Practitioners often face the situation of comparing any set k distributions, which may follow neither normality nor equality variances. We propose a semiparametric model to compare those distributions using an exponential tilt method. This extends classical analysis variance models when all are unknown by relaxing its assumptions. The proposed is optimal one known. Large-sample estimates parame...

Large scale changes to lipid bilayer shapes are well represented by the Helfrich model. However, there are membrane processes that take place at smaller length scales that this model cannot address. In this work, we present a one-dimensional continuum model that captures the mechanics of the lipid bilayer membrane at the length scale of the lipids themselves. The model is developed using the Co...

This paper describes a method for calibrating a pan-tilt camera head. The key feature of the method is that the camera, the pan-tilt unit, and the relationship between the camera and the pan-tilt unit, are calibrated independently. This paper develops a geometric model of the pan-tilt camera head and presents procedures to estimate the values of the unknown model parameters. Target image reposi...

AIMS This study examined the occurrence, magnitude, and the consequences of a possible tilt between the corneal surface and optical axis of the EyeSys videokeratoscope. METHODS Initially, a theoretical model was developed to calculate the angle of tilt. The predictions of the model were verified empirically using a convex conicoid surface and were found to predict the tilt to within 0.5 degre...

Measurement of tilt is having a very much importance in the applications such as railway track monitoring, mining, aviation, tunneling, bridge and dam monitoring system, etc. The tilt is measured in terms of degrees and is made with respect to the original tilt of the surface on which the meter is kept. This paper proposes an embedded tilt measurement system, which uses a level sensor, A/D conv...

measurements of the tilt angle of potential fields can be a useful aid to their interpretation. there are several varieties of the methods in use, such as tilt angle, and the derivative of tilt angle. tilt angle filters are used for exact edge detection of the rectangular bodies artificially by writing a matlab code. the gravity effects of these models are computed by standard algorithms. the e...
