Colour holography in optics courses at Lund Institute of Technology

Several physics courses are given at Lund Institute of Technology. In the basic courses on ray and wave optics, holography has played an important role both in stimulating the students to curiously investigate the optical world and as an important visualisation of some obvious and interesting parts of the courses. To meet the need for basic laboratory experience, a holographic laboratory has been

Control of moisture safety design by comparison between calculations and measurements in passive house walls made of wood

The use of passive house technique has been used in a new wood framed building in Sweden. Besides the positive effect of reduced energy need, highly insulated wooden houses often have a higher risk of moisture and mould problems. The reason is that critical positions is more exposed to higher relative humidity compared to ordinary houses with thinner insulation. To investigate if an external wall

Post-Tsunami Recovery in Thailand: Socio-cultural responses

Of all the huge natural disasters that claimed the lives of thousands in Asia, the Indian Ocean tsunami in 2004 was the largest, estimated to have killed more than 230,000 people. The scope of damage brought about by this natural disaster urges focus on recovery and post-disaster reconstruction from several perspectives. Here we find an in-depth ethnography of Thailand and the role of culture and

Energy use, population and growth, 1800-1970

In this paper, the role of energy use is incorporated into unified growth theory. The paper presents some interesting evidence about the evolution of energy in the transition from stagnation to growth, and it subsequently develops a growth model where the observed increase in conversion efficiency in the coal energy sector is explicitly modelled and calibrated to existing data over the period 1800

A Control Theory Approach for Analyzing the Effects of Data Errors in Safety-Critical Control Systems

Computers are increasingly used for implementing controlalgorithms in safety-critical embedded applications, such asengine control, braking control and flight surfacecontrol. Addressing the consequent coupling of control performancewith computer related errors, this paper develops a composite computerdependability/control theory methodology for analyzing the effectsdata errors have on control syst

Universal Lossless Source Coding Techniques for Images and Short Data Sequences

Popular Abstract in Swedish Denna avhandling behandlar olika metoder för datakompression och speciellt metoder som är lämpliga för komprimering av digitala bilder. Avsikten med datakompressionen är att finna en representation av den ursprungliga datan (tex en bild) som upptar mindre plats på tex ett skivminne.In this thesis various topics in universal lossless source coding are discussed and analyzed. The main focus in this work is on lossless data compression of grayscale still images. Such images are, for example, frequently occurring in medical imaging. Based on theoretical considerations and empirical observations new compression algorithms are presented that are, in terms of compression performan

Course Experience Questionnaire och högskolepedagogik

Detta dokument beskriver huvuddragen i relationen mellan Course Experience Questionnaire (CEQ) och högskolepedagogik. Syftet är att visa på hur resultat från CEQ kan användas för pedagogisk utveckling. Därmed behandlar detta dokument kärnan i CEQ-tolkningsprocessen inom LTH:s system för rapporterande utvärdering, själva syftet med CEQ-utvärderingarna, samt LTH:s utvärderingssystems koppling till s

Surface Vibrational and Electron Spectroscopy - Experiments and first-principle calculations

Popular Abstract in Swedish 75% av alla kemiska reaktioner sker på en yta av något slag. En av anledningarna till detta är att många ytor har en katalytisk effekt. Inom kemins värld är en katalysator något som påskyndar en kemisk reaktion utan att själv förbrukas, och ett tydligt exempel på en katalytiskt aktiv yta är en bilkatalysator, vilken i princip består av en varm metallyta. På denna yta omThis work deals with interpretation of experimental surface spectroscopic data with the aid of first-principle calculations. Surface infrared reflection-absorption spectra as well as spectra from the electron spectroscopic methods photoemission and X-ray absorption are considered. In all cases the surface is modeled by a metal cluster with the same (frozen) geometry as part of the surface. The wo

Proposals for targets and indicators for waste prevention in four waste streams

This study, commissioned by the Nordic Council of Ministers, aimed toprovide first proposals for targets and indicators that can be used in the Nordic countries' waste prevention programmes. Four waste streams were considered: food waste, construction- and demolition waste (C&D waste), waste electrical and electronic equipment (WEEE) and textile waste. Firstly, a literature review of internati
