1. 1. Evaluating aperture shape controller (ASC) in modulated radiation treatments

   University essay from

   Author : Vilma Andrén Cederholm; [2023-09-28]
   Keywords : Medical physics;

   Abstract : To decrease aperture complexity, the aperture shape controller (ASC) is a recently introduced function in Eclipse external beam planning (Varian Medical Systems, Palo Alto, USA). ASC works within the photon optimizer, minimizing distances between adjacent leaf tips of the MLC. READ MORE

3. 2. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

   University essay from KTH/Teknisk mekanik

   Author : Simon Garpenquist; [2023]
   Keywords : Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

   Abstract : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. READ MORE

4. 3. Microfluidic flow splitter shape optimization for high throughput

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Christoffer Papamoustos Palmér; Joel Linder; [2023]
   Keywords : Genetic algorithms; Lab-on-a-chip; Optimization; Acoustofluidics; Microfluidics; Technology and Engineering;

   Abstract : Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. READ MORE

5. 4. Adjoint-based Formulation for Shape Optimization Problems in Computational Fluid Dynamics

   University essay from KTH/Matematik (Avd.)

   Author : Anton Scotte; [2023]
   Keywords : ;

   Abstract : A continuous adjoint formulation for exterior optimization of Dirichlet data on the boundary for potential flow applications has been developed in this thesis. This has been performed by utilizing boundary integral methods for both the primal problem (Laplace’s equation) and for the corresponding adjoint equation (Poisson’s equation) on the unit disc.
