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

Kursen Arbetsorganisation (MAM026, 3p) är väletablerad men de senaste åren har vissa förändringar genomförts (Blomé, 2003) och numera ingår tre olika moment vid examinationen: dugga, poster och skriftlig tentamen. Drivkraften till att utveckla poster som kompletterande examinationsform har varit att öka inslagen av reflektion och aktivt experimenterande, vilket är viktiga inslag för att skapa lära

The purpose of this paper is to define and discuss the core-customer concept. This concept examines how a company develops its operations around a single or only a few customers. The customer steers what products and services the supplier develops, which means that it is the customer that dictates the supplier's operations. The core-customer concept may be one method for designing a company's oper

A Fortran program for analysis of spectra obtained in proton induced x-ray emission spectroscopy is under development. The first version is working and some results are shown. The program uses a model which describes the physics involved in the analysis. The continuum is described by an exponentially decreasing function representing secondary electron induced bremsstrahlung and a constant approxim

In this lecture, we will discuss the emergence of the semiotic function, both ontogenetically and phylogenetically, and we will consider the part played by the picture sign in this development. In order to demonstrate that pictures are indeed signs, we will explore the basic elements of the sign presupposed but never put into focus neither by Saussure nor by Peirce. Indeed, explorations in the psy

The Swedish HE Ordinance requires all supervisors of doctoral students to undergo introductory training. The content, goals, learning outcomes and duration is not specified by the Ordinance and thus practices vary between institutions. In 2009/2010, a new study program for doctoral supervisors was launched at Lund University. The program was designed to:- provide research-based support for doctora
