Popular Abstract in Swedish Den här avhandlingen handlar om att skräddarsy mikroorganismer så att de kan utföra specifika kemiska reaktioner. Nästan alla material och produkter vi har omkring oss idag har framställts genom kemiska metoder. Ofta används olja vilken så småningom kommer sina, som utgångskemikalie. När de framställda produkterna sedan förbränns efter användning släpps koldioxid ut vilChiral building blocks are important molecules for synthesis of fine chemicals and pharmaceuticals. Biocatalysis has gained in relevance over traditional organic methods for synthesis of chiral compounds, as reactions can be performed at high enantio-selectivity and purity with environmentally friendly, simple, and cheap methods. The aim of the present study was to explore the feasibility of using

Large-scale software development is a complex undertaking and generates an ever-increasing amount of information. To be able to work efficiently under such circumstances, navigation in all available data needs support. Maintaining traceability links between software artefacts is one approach to structure the information space and support this challenge. Several researchers have proposed traceabili

In this paper the frequency domain sensitivity shaping of pole placement controllers is discussed. The sensitivity function is shaped in order to improve robustness and disturbance attenuation, and it is done with the use of controller overparametrization. A design example shows the capabilities of the method. The computation is done by a weighted least squares procedure which is suitable for adap

In this paper, a novel transmission technique for the multiple-input multiple-output (MIMO) broadcasting directional channels is introduced. During the training period, the base station sends a set of mutually orthogonal signals which enables each user to estimate the angle-of-departure of the anticipated strongest beam and the corresponding SNR. Then, the base station uses the reported angles-of-

The most important trends in landfill management policy over the last decade have been the universal adoption of the containment approach to emission control and the increasing legal requirement to install artificial membranes as bottom liners and caps to landfills which is now mandatory in many countries. The landfill cover is one of the most important aspects when designing and constructing land

This paper is dedicated to model order reduction of linear time-invariant systems. The main contribution of this paper is the derivation of two scalable stability-preserving model reduction algorithms. Both algorithms constitute a development of a recently proposed model reduction method. The algorithms perform a curve fitting procedure using frequency response samples of a model and semidefinite

Den muslimska fastemånaden ramadan har just inletts. Att fasta av religiösa skäl kan tyckas svårförståeligt i dagens sekulära svenska samhälle. Risken är att den sekulära livsåskådningen leder till intolerans och utestängande, skriver André Möller och Pierre Wiktorin, religionsantropologer med anknytning till Lunds universitet.
