  1. 21. Optimization of an advanced algorithm for bone imaging

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Adam Mrozek; [2022]
    Keywords : osteoporosis; optimization; programming; engineering; X-ray; bone; mineral density; speed; faster; projection; MATLAB; C ; Technology and Engineering;

    Abstract : Fracture risk in osteoporosis is increased and osteoporosis is the most common metabolic bone disease and treatment is expensive. Osteoporosis is diagnosed by measuring Bone Mineral Density (BMD), which does not consider other factors such as bone geometry or architecture. READ MORE

  3. 22. Pre-Straining Operation : Prediction of Strain Paths Within a Forming Limit Diagram

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Elin Olofsson; Mohammed Al-Fadhli; [2022]
    Keywords : Forming Limit Diagram; Forming Limit Curve; Non-Linear Strain Paths; Pre-Straining; Sheet Metal Forming.;

    Abstract : In a Sheet Metal Forming (SMF) operation, complex geometries in multi-stage forming processes are mostly common. Forming a blank, major and minor straining willoccur. Follow the straining of the blank elements over the forming process will provide its strain paths. READ MORE

  4. 23. Idealised remediation scenario in two small-scale intersecting fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Agnes Zúniga Ekenberg; [2022]
    Keywords : ;

    Abstract : Analysis of mass transport in rock fractures has become increasingly important in underground storage of radioactive materials and remediation of polluted groundwater in fractured rock aquifers. Permeability of rock mass is regulated by present rock fractures, where flow is mainly through the fracture networks. READ MORE

  5. 24. Fracture analysis of tensile- and fatigue failure for perforated and wedge wire structures

    University essay from

    Author : David Barjosef; Alexander Austen Öhrn; [2022]
    Keywords : ;

    Abstract : In the effort to produce more durable filters and understand their mechanical failure, this study presents distinctive indicators on the cause of failure for welded perforated- and wedge wire sheets in 316L stainless steel, super duplex UR52N stainless steel and grade 2 titanium. The study achieves this by fracture analysis on specimens from tensile strength- and fatigue testing. READ MORE

  6. 25. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

    University essay from KTH/Materialvetenskap

    Author : Filip Ivarsson; [2022]
    Keywords : Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

    Abstract : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this  thesis  aims  to  broaden  the  knowledge  and  answer  whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.
