1. 1. Parametric model for astrophysical proton-proton interactions

   Författare :Niklas Karlsson; Per Carlsson; Johan Rathsman; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : Observations of gamma-rays have been made from objects such as active galaxies and supernova remnants and also as diffuse emission from the Galactic ridge. The study of gamma-rays can provide information about production mechanisms and tell us about cosmic ray acceleration. LÄS MER

3. 2. Inverse Problems in Analytic Interpolation for Robust Control and Spectral Estimation

   Författare :Johan Karlsson; Anders Lindquist; Alberto Isidori; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nevanlinna-Pick Interpolation; Approximation; Model Reduction; Robust Control; Gap-robustness; Sensitivity Shaping; Entropy functional; Spectral Estimation; Weak*-topology; Monge-Kantorovic Transportation; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : This thesis is divided into two parts. The first part deals with theNevanlinna-Pick interpolation problem, a problem which occursnaturally in several applications such as robust control, signalprocessing and circuit theory. We consider the problem of shaping andapproximating solutions to the Nevanlinna-Pick problem in a systematicway. LÄS MER

4. 3. Improved techniques for CE-MALDI-MS off-line coupling and MALDI-MS analysis of primarily hydrophobic proteins and peptides

   Författare :Johan Jacksén; Åsa Emmer; Anna Karin/Minna Borg Karlsson/Hakkarainen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Capillary electrophoresis; Hydrophobic peptides; Matrix-Assisted Laser Desorption Ionization Mass Spectrometry; Prestructured target; Off-line interface; Silicon microcanal; Matrix; Protein cleavage digestion.; Kapillärelektrofores; Hydrofoba peptider; Matris-assisterad laserdesorptions-joniserings-masspektrometri; Strukturbelagd provplatta; Off-line interface; Mikrokanal i kisel; Matris; Proteinklyvning -spjälkning.; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Due to the hydrophobic nature of integral membrane proteins (IMP) they give rise to several difficulties concerning handling and analysis, which is not the case for the most water soluble proteins. New analysis methods are needed, where the insolubility problems of the hydrophobic proteins due to aggregation and adhesion are tackled. LÄS MER

5. 4. Klassicismens interiörer : Inredningskonst och arkitekturprofiler från Vitruvius till Tessin

   Författare :Stefan Günther; Johan Mårtelius; Fredric Bedoire; Ove Hidemark; Lars Karlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architectural theory; Historiography; Architecture; Interior decoration; France; Italy; Sweden; 15th–17th centuries; Vitruvius; Columnar orders; Moulding; Classicism in Art; Design; Conservation; Restoration; Architecture and architectural conservation and restoration; Arkitektur och bebyggelsevård;

   Sammanfattning : The aim of this thesis is to describe and analyse the design and development of the classical interior detail and its theoretical background from its Italian origins through its development into a shared European style around 1700. It mainly presents a close study of some forty chosen interiors in Italy, France and Sweden dating from antiquity to the close of the seventeenth century. LÄS MER

7. 5. Graph-structured multi-marginal optimal transport : Theory, applications, and efficient methods using entropy regularization

   Författare :Isabel Haasler; Johan Karlsson; Michele Pavon; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Optimization and Systems Theory; Optimeringslära och systemteori;

   Sammanfattning : This thesis deals with a class of multi-marginal optimal transport problems, which we call graph-structured multi-marginal optimal transport. The aim of the thesis is to work towards a unified framework for this class of problems. The included papers explore theoretical, computational, and practical aspects of the novel framework, e.g. LÄS MER
