  4. 2. Defects and Surfaces and their Impact on Fatigue Behaviour of Powder Bed Fused Ti-6Al-4V : Characteristics and Modelling

    Author : Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Stefano Beretta; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Extreme Value Statistics; Materialteknik; Engineering Materials;

    Abstract : Additive manufacturing (AM), of metals is gaining popularity as an alternative to conventional manufacturing techniques such as casting and forging. Metal-AM allows for the production of complex part geometries with reduced material waste and shorter lead times. READ MORE

  5. 3. Beam Modelling for Treatment Planning of Scanned Proton Beams

    Author : Peter Kimstrand; Bengt Glimelius; Erik Traneus; Nina Tilly; Anders Ahnesjö; Thomas Bortfeld; Uppsala universitet; []
    Keywords : Radiation sciences; proton therapy; treatment planning; beam modelling; dose calculation; Monte Carlo; Strålningsvetenskap;

    Abstract : Scanned proton beams offer the possibility to take full advantage of the dose deposition properties of proton beams, i.e. the limited range and sharp peak at the end of the range, the Bragg peak. READ MORE

  6. 4. Railway track dynamic modelling

    Author : Blas Blanco; Leif Kari; Stefano Bruni; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track modelling; Timoshenko element; local deformation; response discontinuity; distributed supports; Engineering Mechanics; Teknisk mekanik;

    Abstract : The railway vehicles are an increasing mean of transportation due to, its reduced impact on environment and high level of comfort provided. These reasons have contributed to settle a positive perception of railway traffic into the European society. READ MORE

  7. 5. Modelling late toxicity in hypofractionated radiation therapy

    Author : Niclas Pettersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypofractionation; normal tissue complication probability; modelling; linear-quadratic model; fractionation sensitivity; late toxicity; radiation-induced rib fracture; genitourinary toxicity; stereotactic body radiation therapy; high-dose-rate brachytherapy; multimodality radiation therapy; patient-reported outcomes; prostate cancer; nsclc;

    Abstract : In hypofractionated radiation therapy (RT), the treatment is delivered by few fractions with high doses per fraction. This is in contrast to conventionally fractionated RT where the total dose is delivered in many fractions with low doses per fraction. READ MORE
