  1. 21. Model Based Reconstruction of Ultrasonic Images

    Författare :Erik Wennerström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis is concerned with reconstruction methods for ultrasonic imaging, primarily applied to non-destructive material inspection. In ultrasonic inspection, a specimen is insonified with pulses of high frequency ultrasound, which enters the material and propagates through it. LÄS MER

  3. 22. Pushing the Boundaries of Biomolecule Characterization through Deep Learning

    Författare :Henrik Klein Moberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Vision; Optical Microscopy; Artificial Intelligence; Biological Imaging; Molecule Characterisation; Deep Learning; Nanofluidic Scattering Microscopy;

    Sammanfattning : The importance of studying biological molecules in living organisms can hardly be overstated as they regulate crucial processes in living matter of all kinds. Their ubiquitous nature makes them relevant for disease diagnosis, drug development, and for our fundamental understanding of the complex systems of biology. LÄS MER

  4. 23. Holistic Assessment of Survival Time after Ship Collision

    Författare :Per Hogström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; ship collision; sheet metal failure; uncertainty analysis; Damage stability;

    Sammanfattning : Collisions between ships contribute to ship losses even in modern time, and the International Maritime Organization (IMO) strives towards a more risk-based view on addressing the damage stability of ships. This thesis presents a holistic methodology for computing the consequences of ship collisions. LÄS MER

  5. 24. Fluid dynamics and mass transfer in bubble columns with and without packing

    Författare :Peter Therning; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; packed bubble column; fluid dynamics; bubble column; laser doppler anemometry LDA ; mass transfer; hydrodynamics; multiphase reactor; dispersion;

    Sammanfattning : Bubble columns are used in the chemical industry to perform gas liquid reactions, like oxidation, hydrogenation and fermentation. The objective of the present thesis was mainly to study the fluid dynamics of semi batch packed bubble columns at both atmospheric and pressurized conditions. LÄS MER

  7. 25. The Physical Environment and Occupant Thermal Perceptions in Office Buildings An Evaluation of Sampled Data from Five European Countries

    Författare :John Leland Stoops; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal sensation; Europe; thermal preference; seasonal variation; office buildings; temperature perception; outdoor temperature; interior temperature; field study; thermal comfort; Clo; Met; carbon dioxide;

    Sammanfattning : The results from a large field study of thermal comfort in European office buildings are reported. Measurements of physical environmental conditions and occupant perceptions were collected over sixteen months from twenty-six different office buildings located in France, Greece, Portugal, Sweden and the UK.
