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

    Författare :Mattias Hansson; Matematik LTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Mattias Hansson; Biokemi och Strukturbiologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Warhead penetration in concrete protective structures

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

    Sammanfattning : 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. LÄS MER

  5. 4. I den goda vårdens namn : Sinnesslövård i 1950-talets Sverige

    Författare :Sara Hansson; John Rogers; Mattias Tydén; Uppsala universitet; []
    Nyckelord :History; feeble-minded; mental deficiency; IQ-testing; differentiation; institutional care; modernity; rationality; pedagogy; psychology; experts; Sweden; 1950s; welfare state; social engineering; Slagsta; Hans Forssman; Torsten Thysell; mass media; National Medical Board; individualization; Historia;

    Sammanfattning : In 1952 the Swedish parliament commissioned a total evaluation of 13,000 institutionalized individuals designated in the terminology of the day as feeble-minded. The evaluation provides a unique opportunity to attain new knowledge about how the system of institutionalized care of the feeble-minded developed, functioned and was eventually transformed. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
