Biometrics based personal authentication is an effective way for automatically recognizing, with a high confidence, a person's identity. Recently, 3D ear shape has attracted tremendous interests in research field due to its richness of feature and ease of acquisition. However, the existing ICP (Iterative Closet Point)-based 3D ear matching methods prevalent in the literature are not quite effic...

In sound field synthesis a given arrangement of elementary sound sources is employed in order to synthesize a sound field with given desired physical properties over an extended region. The calculation of the driving signals of these secondary sources typically assumes free-field propagation conditions. The present paper investigates the scattering of such synthetic sound fields from unavoidabl...

Congenital blind subjects are able to learn how to use color terms and other types of vision-related words in a way that is de facto undistinguishable from sighted people. It has actually been proposed that language provides a rich source of information that blind subjects can exploit to acquire aspects of word meaning that are related to visual experience, such as the color of fruits or animal...

Multitemporal thermal imagery in conjunction with a diurnal temperature model provides a well-known means to derive physical properties of the earth’s surface. Classification applications based on such data sets can be used for clustering image pixels with similar heating behaviour. For that purpose, the covariance matrix which describes the mutual dependence of the used features (i.e. temperat...

This paper focuses on heavy metal distribution patterns in sediments of central Guilan (CG) and east Mazandaran (EM) in the south Caspian Sea coasts, north of Iran. Sediment sub-samples were retrieved from core and surficial samples in different environments of marine and coastal lagoons as well as coastal outcrops. Inductively Coupled Plasma Mass Spectrometry and Atomic Emission Spectrometry (...
