  2. 21. Predicting Normal Tissue Complications after External Beam Radiation Therapy

    Author : Caroline Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NTCP; fractionation effects; radiobiological modelling; pubic bone pain;

    Abstract : Although modern external beam radiation (EBRT) therapy has the ability to conform the dose tightly around the volume to be treated, unwanted irradiation to surrounding normal tissue is still a problem. The probability of a side effect arising in normal tissue after EBRT is commonly modelled by an s-shaped dose-volume response curve where dose or volume are plotted against response (i. READ MORE

  4. 22. Information geometries in black hole physics

    Author : Narit Pidokrajt; Ingemar Bengtsson; Jorma Louko; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; black holes; thermodynamics; instability; hessian; entropy; ruppeiner geometry; weinhold geometry; information geometry; Theory of relativity; gravitation; Relativitetsteori; gravitation; teoretisk fysik; Theoretical Physics;

    Abstract : In this thesis we aim to develop new perspectives on the statistical mechanics of black holes using an information geometric approach (Ruppeiner and Weinhold geometry). The Ruppeiner metric is defined as a Hessian matrix on a Gibbs surface, and provides a geometric description of thermodynamic systems in equilibrium. READ MORE

  5. 23. Phase dependent heat transport in superconducting junctions with scattering theory

    Author : Fatemeh Hajiloo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; heat transport; heat conductance; scattering theory; superconducting hybrid devices; conductance fluctuations; phase dependent heat currents;

    Abstract : The operation of nanoscale devices at low temperatures is highly sensitive to heating effects. This motivates current research on controlling heat currents in these devices. READ MORE

  6. 24. On the Use of Laser-Induced Incandescence for Soot Diagnostics: From Theoretical Aspects to Applications in Engines

    Author : Henrik Bladh; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser-Induced Incandescence; Laser Diagnostics; LII; Soot; Model; Engine; Particulates; Soot volume fraction; Combustion; Physics; Fysik; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; relativity; kvantmekanik; klassisk mekanik; termodynamik; statistisk fysik; relativitet; Gases; Gaser; fluid dynamics; plasmas; Teknik; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem; fluiddynamik; plasma; Technological sciences; Laser technology;

    Abstract : The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. READ MORE

  7. 25. Exactly Solvable Models for Self-Assembly

    Author : Erik Edlund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The field of self-assembly studies the spontaneous formation of order from preexisting components.It holds the promise of fabricating tomorrows materials and devices not by traditional methods, but by designing building blocks that will act as supramolecular ``atoms'' and form the desired structures without external input.
