Parameter distortion by unappropriate nonisothermal treatment
Journal of Thermal Analysis, 1989The aim of this contribution is to draw attention to the following problems: (i) boundary conditions of kinetic models, (ii) distortion of kinetic data by cutting-off the peak ends, (iii) regression analysis involved in the evaluation of kinetic data.

Assessment of the Influence of Welding Parameters on Distortion
Applied Mechanics and Materials, 2014The welding involves the transfer of high localized heat flow, which results in residual stresses in the welded body. The impossibility of relieving these stresses generates welding distortions that become a problem in dimensional setting of welded structures.

Influence of manufacturing parameters on gear distortion
Materialwissenschaft und Werkstofftechnik, 2012AbstractRealising the system‐oriented approach of “Distortion Engineering”, the influence of multiple parameters on the distortion of cylindrical gears was investigated by design of experiments. Aim of this research work was to investigate the effect of production parameters before the final heat treatment.

ONE‐PARAMETER FAMILIES OF DISTORTION RISK MEASURES
Mathematical Finance, 2009This paper introduces parametric families of distortion risk measures, investigates their properties, and discusses their use in risk management. Their derivation is based on Kusuoka's representation theorem of law invariant and comonotonically additive coherent risk measures.

On the use of SDF-type filters for distortion parameter estimation
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2002Synthetic discriminant functions have been used to locate objects irrespective of distortions and to estimate the extent of the distortion. It was recognized from the beginning that accurate estimates are only possible provided the training set is constructed carefully. We obtain conditions that will ensure the accuracy of the estimates. The conditions

Estimation of spatial distortion as a function of geometric parameters of perspective
IEEE Transactions on Systems, Man, and Cybernetics, 1995As part of a study on the relationship between geometric parameters of perspective and judgments of spatial information, 15 subjects estimated the degree of spatial distortion within a computer-generated perspective display. The experiment task was to estimate "skewness," the projected angle (in screen spate coordinates) between two parallel vertical ...

[Standard parameters of distortion products].
Acta otorrinolaringologica espanola, 1995In this study we have analyzed the incidence, range, frequency spectrum and threshold of distortion products in a sample of 232 normal hearing person. 116 younger adults, 58 female ranging in age from 18 to 30 years (mean age 23.1) and 58 males ranging in age from 18 to 32 (mean age 23.7) were included in the study.

The effect of stereoscopic acquisition parameters on both distortion and comfort
SPIE Proceedings, 2014The purpose of our experiments was to investigate the effect of interaxial camera separation on the perceived shape and viewing comfort of 3D images. Horizontal Image Translation (HIT) and interaxial distance were altered together. Following Banks et al (2009), our stimuli were simple stereoscopic hinges and we measured the perceived angle as a ...

Influence on PD parameters due to distorted voltage
2003 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2004In the standard specification of AC dielectric-characteristic measurements of insulating materials, test voltage is prescribed as "approximately sinusoidal" if the highest acceptable deviation of the HV waveform from the correct sinusoidal shape is limited in a /spl plusmn/5% tolerance range of the crest factor value. In the field of Partial Discharge (
