  1. 1. Volumetric reconstruction and representation with applications in radiotherapy planning

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Emma Villemoes; [2018]
    Keywords : Volume reconstruction from contours; shape-based interpolation; adaptively sampled distance field; radiotherapy planning;

    Abstract : Optimization and planning of radiation therapy is performed in a treatment planning system. This includes the definition of target structures to be irradiated and organs at risk to be protected, typically performed by contouring structures slice by slice in the image data. READ MORE

  2. 2. Reflected Stochastic Differential Equations on a Time-Dependent Non-Smooth Domain

    University essay from KTH/Matematisk statistik

    Author : Adam Lindhe; [2018]
    Keywords : Reflected stochastic differential equations; non-smooth; timedependent; Skorokhod problem; Reflekterande stokastiska differentialekvationer; icke-slät; tidsberoende;

    Abstract : In this thesis we prove existence and uniqueness for reflected stochastic differential equation on a specific non-smooth, time-dependent domain. The domain is the intersection of a finite number of smooth domains that are allowed to vary in time. READ MORE

  3. 3. Analysis and implementation of the Smooth Discrete Element Method in AgX

    University essay from Linköpings universitet/Linköpings universitet/BeräkningsmatematikTekniska fakulteten

    Author : Thomas Pettersson; [2015]
    Keywords : Granular Dynamics; Discrete Elemant Method;

    Abstract : We encounter granular materials on a daily basis. We walk up a gravel path or we eat our breakfast cereals. When handling granular materials on an industrial scale it is important to do so efficiently, to avoid unnecessary energy losses, wear and tear. READ MORE

  4. 4. Load Unit Geometry Optimization for Heavy Duty Machinery

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ted Samuelsson; [2015]
    Keywords : Design Optimization; Geometry Optimization; Finite Element Method FEM ; Gradient Based Optimization; Wheel Loader; Backhoe Loader;

    Abstract : The construction equipment industry is developing at a fast pace, increasing the expectation on the next-generation machines. Wheel loaders and backhoe loaders are part of this evolution and all subsystems in those machines need to be developed to meet the high demands in energy eciency and productivity. READ MORE

  5. 5. Discrete time variational mechanics of multidomain systems : Applications to coupled electronic, hydraulic, and multibody systems

    University essay from Umeå universitet/Institutionen för fysik

    Author : Tomas Sjöström; [2012]
    Keywords : ;

    Abstract : Today there exist few non-smooth multi-domain simulation tools using time-discretized Lagrangian mechanics for circuits.The main goal is to show that itis possible to use a semi-implicit, parameter free non-smooth variational timestepper to simulate the circuits with time-steps proportional to the system timescales.
