16. Preparations for photon external beam radiotherapy treatment planning of small animals
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE

17. Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling
University essay from KTH/Bro- och stålbyggnadAbstract : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. READ MORE

18. Wood and moisture-induced strains in a large deformation setting in 3D
University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

19. Comparing different methods of measuring particle size for pharmaceutical excipients
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

20. 2D & 3D phase retrieval for propagation-based X-ray phase-contrast tomography
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : Propagation-based X-ray phase-contrast tomography is a 3d imaging technique that utilizes two-dimensional projections from different angular views $\theta =[0,\pi]$ to reconstruct the 3D object information. The phase-contrast allows for higher feature contrast than conventional transmission tomography, as the phase interference gives rise to a sharp edge contrast. READ MORE
