Swedish Butterfly Monitoring Scheme, annual report for 2014

This is the fifth annual report of the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedish

A first-principles approach to protein–ligand interaction

It is still impossible to make an accurate, purely theoretical prediction of the free energy of a ligand binding to a protein in aqueous environment. The two main problems are the immense number of nuclear configurations contributing to the binding free energy and the impossibility to apply accurate quantum-chemical methods to such a large system, even for a single configuration. In this thesis, t

Carsim: A System to Visualize Written Road Accident Reports as Animated 3D Scenes

This paper describes a system to create animated 3D scenes of car accidents from reports written in Swedish. The system has been developed using news reports of varying size and complexity. The text-to-scene conversion process consists of two stages. An information extraction module creates a structured representation of the accident and a visual simulator generates and animates the scene. We firs

Witnessing the Unbearable. Alma Johansson and the Massacres of the Armenians 1915

In 1915, Swedish missionary Alma Johansson witnessed the Armenian genocide in the Ottoman Empire. She then worked at an Armenian orphanage. When the children became victims of the killings it was important for her to report the outrages to diplomats and to write about her experiences. Johansson also continued to work with Armenian refugees. The chapter focuses on a civil female actor in a war zon

Load Management in Residential Buildings: Considering Techno-Economical and Environmental Aspects

Load problems in electricity markets occur both on the supply and demand side and can have technical, economic and even political causes. Commonly, such problems have been solved by expanding production and/or distribution capacity, importing electricity or by load management. Load management is a techno-economic measure for harmonizing the relations between supply and demand sides, optimizing pow

Purification of Plasma Membranes by Affinity Partitioning

This chapter describes the purification of rat liver plasma membranes by affinity partitioning in an aqueous polymer two-phase system using the lectin wheat germ agglutinin (WGA) as affinity ligand. Affinity partitioning is advantageous for conventional membrane fractionation techniques in being highly selective, allowing the rapid and high-yield purification of membranes. In addition, the aqueous

Application of Protograph-based LDPC Codes for UWB Short Range Communication

We studied the behavior of an iterative receiver using protograph based LDPC codes (PG-LDPCC) in an UWB short range communication system. An EXIT-Chart-Analysis is applied by means of density evolution of protographs. We show that AWGN-optimized protograph ensembles perform also well on frequency-flat UWB channels, outperform rate-compatible punctured convolutional codes (RCPC), but degrade with i

Electron Transport in Low Dimensional Systems

Popular Abstract in Swedish Avhandlingen består av transportmätningar på AlGaAs/GaAs och GaInAs/InP heterostrukturer.This thesis consists of experimental studies of transport properties in high mobility two dimensional electron gases (2DEGs). Two material systems are used, an AlGaAs/GaAs heterojunction and a GaInAs/InP quantum well. The AlGaAs/GaAs heterojunction is used for top gating, either to additionally reduce the dimensionality of the 2DEG to observe one dimensional effects, or to explore the edge channe
