  1. 11. Symmetry Breaking Ordering Constraints

    Författare :Zeynep Kiziltan; Andreas Hamfelt; Toby Walsh; Pedro Meseguer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Constraint satisfaction; constraint programming; modelling; symmetry breaking; global constraints; Datavetenskap; Computer science; Datavetenskap;

    Sammanfattning : Many problems in business, industry, and academia can be modelled as constraint programs consisting of matrices of decision variables. Such “matrix models” often have symmetry. In particular, they often have row and column symmetry as the rows and columns can freely be permuted without affecting the satisfiability of assignments. LÄS MER

  3. 12. Optical Measurements of Rolling Friction Coefficients

    Författare :Yiling Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : This thesis presents an optical method to measure the rolling friction coefficientsfor balls rolling freely on a cylindrical surface. Two different models of a ball rollingfreely on a cylindrical surface are established, one is an analytical model and the otheris a numerical model derived from Lagrange equation. LÄS MER

  4. 13. Disease surveillance systems

    Författare :Baki Cakici; Magnus Boman; Stefan Johansson; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; disease surveillance; syndromic surveillance; outbreak detection; health informatics; computer science; Health and medical services in society; Hälso- och sjukvård i samhället; Epidemiology; Epidemiologi; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Recent advances in information and communication technologies have made the development and operation of complex disease surveillance systems technically feasible, and many systems have been proposed to interpret diverse data sources for health-related signals. Implementing these systems for daily use and efficiently interpreting their output, however, remains a technical challenge. LÄS MER

  5. 14. Methodologies to assess the fate of polar organic compounds in aquatic environments

    Författare :Jörgen Magnér; Tomas Alsberg; Dag Broman; Jan-Åke Jönsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Passive equilibrium sampler; Absorbent; Polar organic compounds; Liquid chromatography-mass spectrometry; Partitioning coefficient; Fulvic acid; Sediment; PEVAC; Bag-SPE; Solid phase extraction; Pharmaceuticals; Wastewater; Sea water; UPLC-QToF; Environmental chemistry; Miljökemi; Analytical chemistry; Analytisk kemi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements.

  7. 15. Multi­-Scattering: Computational light transport in turbid media

    Författare :Joakim Jönsson; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monte carlo simulations; scattering in tissues; particulate scattering; GPU; CUDA; Fysicumarkivet A:2021:Jönsson;

    Sammanfattning : This thesis presents and describes the development of an online freely accessible software called Multi-Scattering for the computational modeling of light propagation in scattering and absorbing media. The model is based on the use of the Monte Carlo method, where billions of photon packets are being launched and tracked through simulated cubic volumes. LÄS MER
