Popular Abstract in Swedish Global uppvärmning, säkerhetspolitik och framtida minskad tillgång på fossila bränslen har de senaste åren skyndat på sökandet efter nya, förnyelse-bara drivmedel. Användningen av bioetanol har ökat avsevärt och är idag ett av de vanligaste biobränslena i världen. Idag framställs bioetanol vanligen genom jäsning av socker från socker-rör eller från stärkelse (från tillFuel ethanol from lignocellulose is one sustainable alternative to the fossil fuels of today. All sugars in the material must be utilized in order to achieve high overall ethanol yields. Baker’s yeast, Saccharomyces cerevisiae, has been engineered to ferment the pentose sugar xylose from lignocellulose to ethanol. However, ethanol production from xylose is slow and often incomplete. In this work s

Ultraviolet radiation (UV) has been present longer than any biological life, and during the development of life the radiation intensities were initially high. Eventually a vital ozone layer developed, but despite that this layer screens out most of the high energy wavelengths, some still enter the biosphere and is potentially harmful to life on earth. This thesis investigates the effects of combin

Abstract in French La morphologie verbale de personne-nombre se développe lentement chez les apprenants adultes (suédophones) de français L2. Ce développement, chez eux, ne semble pas relié au développement syntaxique, mais possiblement à des facteurs de fréquence de ces formes dans l’input. On ne peut pas non plus considérer les pronoms sujets chez ces apprenants comme des marqueurs de personne (

A voltage reference has been implemented in a standard 0.35 μm CMOS process. A temperature coefficient of 12 ppm/°C is achieved in virtue of a complete suppression of the temperature dependence of the carrier mobility. The line sensitivity is 0.46 %/V and the maximum supply current, measured at 80°C, is 130 nA. The PSSR at 100 Hz and 10 MHz is -59 dB and -52 dB, respectively.

This is a presentation of the newly established research program entitled "Elderly People and Design" at the Department of Design Sciences, Lund University's Institute of Technology. Several of the departmental research divisions have many years exp

Olika former för äldrevårdsförsäkringar har under senare år lyfts fram i debatten och belysts i flera svenska studier och forskningsrapporter. Denna studie har haft som syfte att studera vilka för- och nackdelar som frivilliga tilläggsförsäkringar kan få i svensk äldreomsorg. Studien förväntas bidra till diskussionen om delar av äldreomsorgens finansiering kan överlåtas till individerna själva gen

In this paper, a stability preserving model reduction algorithm for single-input single-output linear time invariant systems is presented. It performs a data fitting in the frequency domain using semidefinite programming methods. Computing the frequency response of a model can be done efficiently even for large scale models making this approach applicable to those. The relaxation used to obtain a

A resource allocation algorithm aimed at embedded multi- media systems is presented. Particular emphasis is placed on computational efficiency, suitability for fixed point im- plementation and being able to solve the allocation at run- time when parameters or dynamics change. The algorithm is derived from classic convex optimization theory and the resulting real time properties are studied in simu

The optical wave propagation in microcrystalline thin-film silicon solar cells with integrated triangular surface texture was investigated. The influence of the periodic profile dimensions and absorber layer thickness on the short circuit current and quantum efficiencies was analyzed. The optics of the solar cell was calculated by using a finite difference time domain approach to solve the Maxwell

This paper builds on the logical model of opinion dynamics under social influence in networks proposed by Liu, Seligman, and Girard (2014) as well as on the generalization proposed by Christoff and Hansen (2013). While both accounts of social influence show interesting dynamics, they both assume that agents do not reflect on how they are affected by such influence. This paper shows that, if agents
