The importance of using efficient bases for current expansion in numerical computations of electromagnetic field problems has been emphasized for several decades. It is well known that the basis functions should approximate the physical current (electric or magnetic) to some extent. Moreover, for efficiency, it is reasonably to require that only a few basis functions are needed in order to obtain
A brief review is given of some fundamental aspects of high-resolution core-level photoemission and of its application to studies of pure and adsorbate covered metal surfaces. We first give a short description of the basic theory and then turn to a number of examples. The first group of examples is aimed at demonstrating the use of core-level binding energy shifts for deriving the surface and inte
This paper discusses the prospect of a sociology of science informed by the critical realist philosophy of science. The discussion departs from the need for a theoretical framework to account for theoretical struggle and reproduction in the field of econom-ics. The recent talk about an ontological turn in science studies and the wider back-ground for such a turn is then related to the earlier turn
The European solar energy business faces the challenge of developing more cost-effective solar energy systems and one solution could be using concentrating hybrid PVT systems. Two such hybrids, the Swedish systems MaReCo and Solar8, are evaluated in this study. MaReCo is a fixed concentrating system with a high angle of acceptance. Solar8 is a new system, which is under development. It is inspired
A fundamental problem in vision is how to identify the occluding contours of objects and surfaces, given the ambiguity inherent in low-level visual input. A computational model is proposed for how occluding contours could be identified by making use of simple heuristics that reduce the ambiguity of individual features. In the striate cortex, a large majority of cells are selective for both contras
This paper represents the first sketches of what will hopefully grow into a larger postdoctoral project, the subject of which will be the relationship between the world of the Hebrew Bible and that of the Indo-European cultures that was its early neighbours, particularly the Anatolian cultures of the Hittites, Luwians, etc. My goal is to examine how ideas, concepts and words from Indo-European sou
