  2. 1. Statistical Segmentation and Registration of Medical Ultrasound Data

    Author : Mattias Hansson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Registration; Segmentation; Feature descriptor; Statistical image and signal processing; Medical ultrasound; Variational methods; Mixture model; Bayesian; Markov Chain Monte Carlo; Similarity measur;

    Abstract : The interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. READ MORE

  4. 2. Structural and physicochemical studies on metal and porphyrin binding by the Bacillus subtilis ferrochelatase

    Author : Mattias Hansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal specificity; metal binding; porphyrin metallation; time resolved crystallography; fluorescence quenching; X-ray structure; inclusion bodies; Bacillus subtilis; heme biosynthesis; ferrochelatase; hemH;

    Abstract : The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. READ MORE

  5. 3. Warhead penetration in concrete protective structures

    Author : Håkan Hansson; Anders Ansell; Mattias Unosson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Warhead penetration; FE analysis; experiment; material modelling; fortifications; Stridsdelspenetration; FE-analyser; experiment; materialmodellering; fortifikationer;

    Abstract : The analysis of penetration of warheads in concrete protective structures is an important part of the study of weapon effects on protective structures. This type of analysis requires that the design load in the form of a warhead is determined, and its characteristic and performance within a protective structure is known. READ MORE

  6. 4. Response of glaciers to climate change : Mass balance sensitivity, sea level rise and runoff

    Author : Mattias de Woul; Regine Hock; Peter Jansson; Margareta Hansson; Roger J. Braithwaite; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glacier; mass balance modelling; mass balance sensitivity; sea level rise; glacial runoff; Hofsjökull; Storglaciären; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Abstract : The purpose of this study is to enhance our understanding of the response of glaciers to climate change. Global sea level is affected by changes in glacier ice volume, and melt-water from glaciers is a principal water source in many regions. READ MORE

  7. 5. Chemicals in consumer products : Towards a safe and sustainable use

    Author : Linda Molander; Christina Rudén; Sven Ove Hansson; Mattias Öberg; KTH; []
    Keywords : consumer products; articles; hazardous chemicals; risk management; chemicals regulation; REACH; substitution; regulatory toxicology; European Union;

    Abstract : Health and environmental risks associated with emissions of hazardous chemicals from articles, including everyday consumer products such as clothes and toys, have become widely acknowledged internationally, particularly in the EU. This thesis contributes to new understandings of how these risks are currently managed within the EU and recommends actions for ensuring a safe and sustainable use of chemicals in articles. READ MORE
