The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. A code for calcula
We propose a test resource partitioning and optimization technique for core-based designs. Our technique includes test set selection and test resource floor-planning with the aim of minimizing the total test application time and the routing of the added TAM (test access mechanism) wires. A feature of our approach is that it pinpoints bottlenecks that are likely to limit the test solution, which is
A review of recent research, as well as new results, are presented on transition metal oxide clusters, surfaces, and crystals. Quantum-chem. calcns. of clusters of first row transition metal oxides have been made to evaluate the accuracy of ab initio and d. functional calcns. Adsorbates on metal oxide surfaces have been studied with both ab initio and semi-empirical methods, and results are presen
Three-dimensional boundary finding based on Fourier surface optimization is presented as a method for segmentation of SPECT images. Being robust against noise and adjustable with respect to its detail resolution, it forms an interesting alternative in this application area. A three-dimensional approach can also be assumed to increase the possibility of delineating low contrast regions, as compared
Encountering waves overtaking a ship sailing on the ocean may cause instability. Therefore it is of great importance to study the properties of such waves, for example slope, wavelength and amplitude. When making statistics on the properties of overtaking waves, only the waves that are faster than the ship will affect the resulting distribution. Thus the velocity of the individual waves plays an i
A derivation for a polarized CCFM evolution equation which is suitable to describe the scaling behavior of the unintegrated polarized gluon density is given. We discuss the properties of this polarized CCFM equation and compare it to the standard CCFM equation in the unpolarized case.
Adsorption chromatography in expanded beds is a widely used technology for direct capture of target proteins from fermentation broths. However, in many cases this method cannot be applied as a result of the strong tendency of cells or cell debris to interact with the adsorbent beads. To prevent contamination of the expanded bed with the biomass, STREAMLINE DEAE, anion exchanger designed for expand

Popular Abstract in Swedish För att förse en byggnad med rätt luftkvalitet och temperatur behövs ett inneklimatsystem som i denna avhandling är ett samlingsnamn för ventilations-, värme- och kylsystem. Hittills har val av inneklimatsystem i byggnader mest baserats på en lägsta initialkostnad. Med ett livscykel-perspektiv borde de totala kostnaderna och miljöpåverkan från systemen kunna minskas. MoThe indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. There has been a lack of knowledge, models and tools for determining the life cycle cost (LCC) for an indoor climat
Popular Abstract in Swedish Att leverera ett läkemedel till hjärnan är svårt då blod-hjärnbarriären effektivt stoppar de flesta kemiska substanser eller kräver att läkemedlet ges i höga systemiska doser. Om läkemedlet passerar blod-hjärnbärriaren påverkar det i så fall alla strukturer och celltyper. Detta är problematiskt i hjärnan då det här finns avgränsade strukturer med olika funktion, ibland Gene therapy in the brain is a promising treatment strategy that in the future may be used for several brain disorders, including Parkinson's disease, Alzheimer's disease and lysosomal storage diseases. By introducing a new gene, rather than providing a classical pharmacological drug, gene therapy offers the opportunity to treat neurological disorders by a single intervention. However, gene therap
In the work presented in the thesis laser diagnostics was employed primarily in the investigation of engines, but was also used to study soot in flames. Quantitative measurements were performed for visualizing both in-cylinder soot formation and DME sprays in a combustion vessel. The DME sprays inside a diesel truck engine were also qualitatively investigated. The combustion process in the HCCI en
A polymerase chain reaction for the specific detection of mycobacteria belonging to the Mycobacterium tuberculosis complex was developed. Using a single primer pair derived from the nucleotide sequence of protein antigen b of M. tuberculosis, we achieved specific amplification of a 419-base-pair DNA fragment in M. tuberculosis and M. bovis. After DNA was extracted from mycobacteria by using a simp
The ordinary differential equations given by Ljung(1977) are used to analyse the behaviour of a certain adaptive extremal controller. It is shown that this controller will usually converge to the wrong point.This work was supported by the Swedish Board for Technical Development under contract No. 76-3804.
