The development of direct current resistivity imaging techniques has been rapid in the last years. This applies to data acquisition as well as inverse modelling techniques, and has lead to a greatly expanded practical applicability of the method. Resistivity imaging is now becoming widely used in environmental and engineering applications where increased knowledge about the subsurface is sought. T

In a free-electron laser (FEL), the technique of wiggler tapering enables the sustained growth of radiation power beyond the initial saturation. With the goal to develop anX-ray FEL in the terawatt power regime, it is important to utilize this technique and optimize the taper profile,giving the wiggler parameter as a function of the distance along the wiggler line. This article examines two method

The purpose of this chapter is to analyze three persistent charges that Israeli and Western officials persistently leveled against Iranian President Mahmud Ahmadinejad since 2006: 1) that he has threaded to 'wipe Israel off the map the map'; 2) that he is a Holocaust denier; and 3) that he is developing nuclear weapons, presumedly to use against Israel. Although Iran repeatedly has denied all 3 ch

The general goal of this thesis is to elucidate children’s early understandings of pictorial meanings, and how one can know anything about them. My central aim is to explore how picture comprehension develops during children’s first 3 years of life, through semiotic-theory-derived analyses of meaning relations. In so doing, I hope to contribute to the study of both semiotic theory’s psychological

We investigate the bandwidth and distance of codes created by ordinary lowpass filtering of a pulse stream. The encoder is thus a convolution, but over the reals. Performance of these codes is compared to the TCM and PRS code families; despite their simplicity, the new codes perform equally well. Since a simple decoder exists, these are attractive codes.

Changes in evolving software systems are often managed using an issue repository. This repository may contribute to information overload in an organization, but it may also help navigating the software system. Software developers spend much effort on issue triage, a task in which the mere number of issue reports becomes a significant challenge. One specific difficulty is to determine whether a new

A flexible channel decoding platform should be able to operate in varying communication scenarios, and different code rates have to be supported. Therefore, we present a framework that allows efficient processing of rate-flexible trellises. Using a fundamental computational unit for trellis-based decoding, formal principles are obtained to emulate more complex trellises. In a design example, such
