  1. 1. Harmonizing National Laws on Human Trafficking by Implementing Article 3 of the Palermo Protocol : Problems and Reform

    Författare :Dominika Borg Jansson; Petter Asp; Stefan Hedlund; Per Ole Träskman; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Trafficking in human beings; international law; criminal law; organized crime; legal transplants; language; irregular migration; Palermo Protocol; human rights; women’s rights; Criminal Law; Straffrätt;

    Sammanfattning : Trafficking in human beings is one of the most serious and acute problems of our time. It is seen as one of the main forms of organized crime as well as a modern form of slavery. Trafficking is a practice that affects entire societies or rather the very fabric of democratic societies. LÄS MER

  3. 2. Ghosts and machines : regularized variational methods for interactive simulations of multibodies with dry frictional contacts

    Författare :Claude Lacoursière; Bo Kåggström; Ander Klarbring; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Discrete mechanics; Variational method; Contact problems; Impacts; Least action principle; Saddle point problems; Lagrange Multipliers; Constrained systems; Multibody Systems; Numerical regularization; Constraint realization; Constraint stabilization; Dry friction; Differential Algebraic Equations; Nonsmooth problems; Linear Complementarity; Quaternion algebra; Numerical linear algebra; Physics modeling; Interactive simulation; Numerical stability; Rigid body dynamics; Dissipative systems; Computational physics; Beräkningsfysik;

    Sammanfattning : A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts---machines. LÄS MER

  4. 3. Numerical methods for inverse heat conduction problems

    Författare :Fredrik Berntsson; Per Christian Hansen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ill-posed; Heat Conduction; Regularization; MATHEMATICS; MATEMATIK;

    Sammanfattning : In many industrial applications one wishes to determine the temperature history on the surface of a body, where the surface itself is inaccessible for measurements. The sideways heat equation is a model of this situation. LÄS MER

  5. 4. Discrete Velocity Models and Half-Space Problems

    Författare :Niclas Bernhoff; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boltzmann equation; discrete velocity models; half-space problems; Matematik; Mathematics;

    Sammanfattning : We study some questions related to discrete velocity models (DVMs) of the Boltzmann equation. In the case of plane stationary problems the typical DVM reduces to a dynamical system (system of ODEs). Properties of such systems are studied in this paper in the most general case. LÄS MER

  7. 5. Non-linear inverse geothermal problems

    Författare :Dennis Wokiyi; Vladimir Kozlov; Fredrik Berntsson; Mårten Gulliksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The inverse geothermal problem consist of estimating the temperature distribution below the earth’s surface using temperature and heat-flux measurements on the earth’s surface. The problem is important since temperature governs a variety of the geological processes including formation of magmas, minerals, fosil fuels and also deformation of rocks. LÄS MER
