The standard separable 2-D wavelet transform (WT) has recently achieved a great success in image processing because it provides a sparse representation of smooth images. However, it fails to efficiently capture 1-D discontinuities, like edges or contours. ...
When a figure moves behind a stationary narrow slit, observers often report seeing the figure as an integrated whole, a phenomenon known as slit viewing or anorthoscopic perception. Interestingly, in slit viewing, the figure is perceived compressed along t ...
The present paper describes a new method for manufg. a nanostructured porous layer of TiO2 on a conducting glass substrate for use in a dye-sensitized photoelectrochem. cell. The method involves deposition of a layer of semiconductor particles onto a condu ...
Using both vibrational sum-frequency generation and fluorescence microscopy, the phase behaviour of a DPPC lipid monolayer on water is investigated as a function of surface pressure. The vibrational specificity of the sum-frequency generation techniques pe ...
A novel analogue power-efficient 2-D programmable finite impulse response image filter is proposed. This solution is based on the current-mode Gilbert-vector-multiplier operating in the weak inversion region, which allows for ultra low power operation. The ...

Two major classes of models for the multiaxial yield behaviour of aluminium foams are found in the literature. One is based on the foam properties and uses empirical constants determined by fitting of experimental data. The other is based on a mean-field a ...
With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a new standard is currently being developed, the JPEC2000. It is n ...
Media content distribution constitutes a growing share of the services on the Internet. Two distinct distribution approaches used today are Layered Coding (LC) and Multiple Description Coding (MDC). Current wireless connection technologies, e.g. Wimax, hav ...
This paper presents an algorithm in a purely lossless text compression setting based on fountain codes and the Burrows-Wheeler transform (BWT). The scheme consists of five stages, each of which is briefly described in the paper. The algorithm offers encour ...
