  1. 1. Performance of Stress-Laminated-Timber Bridge Decks

    Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; butt joints; non-linear modelling; stress-laminated timber; linear modelling; prestressing; timber bridges; interlaminar slip; FE modelling; laboratory tests; durability;

    Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from a number of timber or glulam beams positioned side by side and stressed together using high-strength steel bars. LÄS MER

  3. 2. Hydrodynamic Modelling for a Point Absorbing Wave Energy Converter

    Författare :Jens Engström; Jan Isberg; Mats Leijon; Antonio Sarmento; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Ocean wave energy; Point absorber; Wave energy converter; Wave energy transport; Polychromatic wave; Linear generator; Resonance; Finite depth; Modelling; Engineering Science with specialization in Electronics; Teknisk fysik med inriktning mot elektronik;

    Sammanfattning : Surface gravity waves in the world’s oceans contain a renewable source of free power on the order of terawatts that has to this date not been commercially utilized. The division of Electricity at Uppsala University is developing a technology to harvest this energy. LÄS MER

  4. 3. Modelling late toxicity in hypofractionated radiation therapy

    Författare :Niclas Pettersson; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. DEM Modelling of Vibratory Screens

    Författare :Ali Davoodi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Validation; Modelling; Screen efficiency; DEM simulation;

    Sammanfattning : In Sweden, about 100 million tons of aggregate is used for road, railway, and concrete every year. Crushing is the main process for producing aggregate material in different fractions. The production process is divided into two sub-processes: comminution or size reduction and classification.

  7. 5. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments

    Författare :Danial Molavitabrizi; Mahmoud Mousavi; Kristofer Gamstedt; Haiyang Yu; Samuel Forest; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot tillämpad mekanik; Engineering science with specialization in Applied Mechanics;

    Sammanfattning : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. LÄS MER
