  2. 1. Micromechanics of Powder Compaction

    Author : Erik Olsson; Per-Lennart Larsson; Christophe Martin; KTH; []
    Keywords : Hållfasthetslära; Solid Mechanics;

    Abstract : Compaction of powders followed by sintering is a convenient manufacturing method for products of complex shape and components of materials that are difficult to produce using conventional metallurgy. During the compaction and the handling of the unsintered compact, defects can develop which could remain in the final sintered product. READ MORE

  4. 2. Real-Time GPU Algorithms: Parallel Primitives and Rendering of Participating Media

    Author : Markus Billeter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; grids; indirect illumination; shafts of light; multiple scattering; stream compaction; single scattering; parallel primitives; GPGPU;

    Abstract : Modern graphics processing units, GPUs, present an immense resource of computational power, that however remains challenging to fully harness. This thesis explores four algorithms and methods that attempt to take full advantage of the resources provided by a GPU. READ MORE

  5. 3. Clocks, DBMs and States in Timed Systems

    Author : Johan Bengtsson; Joost-Pieter Katoen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information technology; Informationsteknik; Datavetenskap; Computer Science;

    Abstract : Today, computers are used to control various technical systems in our society. In many cases, time plays a crucial role in the operation of computers embedded in such systems. This thesis is about techniques and tools for the analysis of timing behaviours of computer systems. READ MORE

  6. 4. Experimental approaches to powder filling and lubrication in powder die pressing

    Author : Erik Hjortsberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; XPS; friction; die filling; interference microscopy; density variations; lubrication; compaction; experimental equipment; tribology; powder metallurgy;

    Abstract : There is a continuous need to improve the mechanical properties of steel parts produced through powder metallurgy in order to ensure the market growth of this sector and competitiveness against alternative production techniques. One of the more promising routes able to achieve this is to aim for components with higher densities. READ MORE

  7. 5. Improved understanding of sublevel blasting : Determination of the extent of the compacted zone, its properties and the effects on caving

    Author : Nikolaos Petropoulos; Daniel Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sublevel mining; compaction; confining material; confined blast; impact tests; burden dynamics; coarse-grained material; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Sublevel caving (SLC) is a mass mining method relying on the flowability of the blasted material. The ore is blasted in slices against caved material which is mainly waste rock. The result of the confined blast is greatly influenced by the interaction between the blasted material and the caved material. READ MORE
