The wavelet transform is a relatively new arrival on the mathematical scene. We give a brief introduction to the subject by showing how the Haar wavelet transform allows information to be encoded according to \levels of detail." In one sense, this parallels the way in which we often process information in our everyday lives. Our investigations enable us to give two interesting applications of w...

Multiplexed diffraction gratings were recorded in 300 μm thick layers of biophotopol photopolymer by using two peristrophic multiplexing schemes separately and in combination. In addition, it was shown that riboflavin may be used as polymer initiator in acrylamide photopolymer films and the holographic properties of these films such as diffraction efficiency and dynamic range were compared with...

This paper considers the problem of comparing real incomes across countries. The available methods are reviewed and their performance is compared using the raw data underlying the Penn World Table. We propose and implement a test of the "Gerschenkron Effect": the downward bias in a country's measured real income when its own prices are used as weights. The test confirms that this Effect obtains...

For musicologists, sources are not only sounds, scores, papers and books. Too often, film and video documentaries on electroacoustic music of the 20 and 21 centuries are unavailable, or at least difficult to find. The main goal of this article is to present a new project begun last 2008: the compilation of a database devoted to filmed documentaries about the process of composing, interpreting a...
