For memory institutions both preservation and presentation of digital art is especially challenging. The digital toolset available to artists is almost infinite as well as their creativity using technology in unconventional ways. In contrast to other sources of digital artifacts with sector-wide quasi-standards on digital formats, each artwork presents a challenge of its own. Hence, each object...

The paper presents a quantitative comparison study of some time−frequency distributions i.e. (TFDs). The comparison is in terms of a criterion known as the Renyi measure. The assessment of the TFDs is accomplished by evaluating the Rényi measure which yields the best time−frequency resolution. We show, using synthetic as well as real−life data, that a recently proposed TFD outperforms existing ...

Music today is more ubiquitous, accessible, and democratized than ever. Thanks to technologies such as high-end home studios, audio compression, and digital distribution, music now surrounds us in everyday life, almost every piece of music is a few minutes of download away, and almost any western musician, novice or expert, can compose, perform and distribute their music directly to their liste...

This paper attempts to assess the Europe-wide systemic risk potential in banking. We employ a bivariate GARCH model to estimate conditional correlations between European bank stock indices. These correlations are used as an indication for the interdependencies amongst the banking business and hence for the systemic risk potential. We employ several tests to assess the development of the systemi...

By Leah Jager∗ and Jon A. Wellner† Grinnell College and University of Washington A unified family of goodness-of-fit tests based on φ−divergences is introduced and studied. The new family of test statistics Sn(s) includes both the supremum version of the Anderson-Darling statistic and the test statistic of Berk and Jones (1979) as special cases (s = 2 and s = 1 respectively). We also introduce ...

We survey a representative subset of applications that use network coding techniques in different environments. We identified two major scenarios in which such applications are used: distributed information storage and retrieval, and content distribution. Moreover, we survey how the inherent properties of network coding can be applied to security and network monitoring, and study existing appli...

A previous publication has described a method of pairwise 3D surface correspondence for the automated generation of landmarks on a set of examples from a class of shape [3]. In this paper we describe a set of improved algorithms which give more accurate and more robust results. We show how the pairwise corresponder can be used in a extension of an existing framework for establishing dense corre...
