During an endoscopic examination pictures from the inside of the human body are displayed on a computer monitor. Often, there are disturbing light reflections visible in these images. In this paper, we present an approach to remove...

We derive the full distribution of transmitted particles through a superconducting point contact of arbitrary transparency under voltage bias. The charge transport is dominated by multiple Andreev reflections. The counting statistics is a multinomial distribution of processes, in which multiple charges ne (n=1,2,3, ...) are transferred through the contact. For zero temperature we obtain analyti...

Our first construction is very similar in spirit to an analogous one in Euclidean space. The group of isometries of Euclidean R is given by O(n) ⊕ R or SO(n) ⊕ R if we want to preserve orientation; the first factor is made up of rotations and reflections (in the non-orientation-preserving case) about the origin, while the second factor gives translations. Now, it turns out that O(n) is generate...

Coxeter classified all discrete isometry groups generated by reflections that act on a Euclidean space or on a sphere of an arbitrary dimension (see [1]). His fundamental work became classical long ago. Lobachevsky spaces (classical hyperbolic spaces) are as symmetric as Euclidean spaces and spheres. However, discrete isometry groups generated by reflections, with fundamental polytopes of finit...

This paper presents a simple model for the evaluation of obstruction caused by multiple buildings in satellite mobile communication systems, or in high-altitude platform (HAP) coverage. The proposed model can be useful for integration into propagation prediction tools. It is based on the KichhoffHuygens formulation, and includes the effect of ground reflections and reflections on a facing build...

Classical room acoustics are based on the interpretation of different sound attributes such as reverberation time, clarity and spatial decay. Based on echograms calculated from a microphone array, the dispersion of early reflections is measured and the reflections are identified. In small auditoriums, the method delivers some comprehensive information of the acoustic paths between the source an...

The effects of the presence of a transparent thin film on a test surface in white-light interferometric surface profiling are investigated. An expression is obtained for the output intensity variations in a Michelson interferometer which includes the effect of multiple reflections within the thin film. The number of reflections that need to be considered to obtain good convergence to the correc...

Among radio amateurs digital meteor burst communication has been discussed for many years. Despite this, no experiments on amateur basis have (to the knowledge of the author) been performed in Sweden or elsewhere in the world. During the past two years several amateurs have reported the random appearance of AX.25 packets from very distant stations. The propagation of these packets can only be e...

We present a framework for automatic inspection of welding seams based on specular reflections. Therefore, we introduce a novel feature set – called specularity features (SPECs) – describing statistical properties of specular reflections. For classification we use a one-class support-vector approach. The SPECs significantly outperform statistical geometric features and raw pixel intensities, si...
