    Abstract : The purpose of this work is to contribute to a process formaking buildings with good function and to avoid prematurefaults.The design, construction and installation of low-slopedroofs are important parts of creating a durable building. READ MORE

  5. 8. Gamma radiation techniques for non-destructive post-irradiation examination of nuclear fuel : Predicting performance and optimizing instrument design

    Author : Lorenzo Senis; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Fabiola Cappia; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Collimated gamma spectroscopy; Gamma emission tomography; Gamma transmission micro-densitometry; Pareto optimization; Post-irradiation examination; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : Collimated gamma-based techniques are widely used to study nuclear fuel, especially for non-destructive post-irradiation examination (PIE). Examples of such techniques include gamma emission tomography (GET) and gamma transmission densitometry (GTD). READ MORE

  6. 9. Shaping Macroporous Ceramics : templated synthesis, X-ray tomography and permeability

    Author : Linnéa Andersson; Lennart Bergström; Ludwig Gauckler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alumina; ceramic; CO2 capture; colloidal processing; expandable microspheres; gel casting; layer-by-layer; macroporosity; near-net shape; non-destructive evaluation; permeability; porosity; sacrificial templating; X-ray computed tomography; Chemistry; Kemi; Materials Chemistry; materialkemi;

    Abstract : Macroporous ceramic materials have found widespread technological application ranging from particulate filters in diesel engines, tissue engineering scaffolds, and as support materials in carbon capture processes. This thesis demonstrates how the pore space of macroporous alumina can be manipulated, analysed in three-dimensions (3D) using visualisation techniques, and functionalised with a CO2-adsorbing material.

  7. 10. Cost/Weight Optimization of Aircraft Structures

    Author : Markus Kaufmann; Dan Zenkert; Frédéric Lani; KTH; []
    Keywords : Cost Weight Optimization; Weight Penalty; Direct Operating Cost; Composite Structures; Non-destructive testing; Finite element analysis FEA ; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Composite structures can lower the weight of an airliner significantly. The increased production cost, however, requires the application of cost-effective design strategies. Hence, a comparative value is required which is used for the evaluation of a design solution in terms of cost and weight. READ MORE
