  1. 1. Perceptual Surface Reconstruction

    University dissertation from Department of Cognitive Science, Lund University

    Author : Jens Månsson; Lunds universitet.; Lund University.; [2005]
    Keywords : HUMANIORA; HUMANITIES; system; kontroll; Psychology; Psykologi; numerisk analys; Datalogi; systems; control; numerical analysis; Surface; Contour; Depth; Vision; Binocular; Computer science;

    Abstract : How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theoretical and computational perspective, as well as through empirical investigations. In paper one, the fundamentals of stereopsis are briefly reviewed, and the difficulties related with resolving the (stereo) correspondence problem are particularly discussed. READ MORE

  2. 2. Sensitivity and Uncertainty Analysis Methods with Applications to a Road Traffic Emission Model

    University dissertation from Matematiska institutionen

    Author : Olle Eriksson; Linköpings universitet.; Linköpings universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik;

    Abstract : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. READ MORE

  3. 3. Oxidative Dissolution of Spent Fuel and Release of Nuclides from a Copper/Iron Canister Model Developments and Applications

    University dissertation from Stockholm : KTH

    Author : Longcheng Liu; KTH.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model; oxidative dissolution; spent fuel; radiolysis; release; mass transport; radionuclide; hydrogen; corrosion; canister; near field; repository; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : Three models have been developed and applied in the performance assessment of a final repository. They are based on accepted theories and experimental results for known and possible mechanisms that may dominate in the oxidative dissolution of spent fuel and the release of nuclides from a canister.

  4. 4. Tribology of stamping : the influence of designed steel sheet surface topography on friction

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Daniel Wiklund; Högskolan i Halmstad.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik; steel sheet; tribology; surface topography; Ytbehandlingsteknik; Surface engineering;

    Abstract : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.

  5. 5. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments

    University dissertation from Chalmers University of Technology

    Author : Amir Malakizadi; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method; metal cutting; bi-metals; inverse identification; Johnson-Cook; Wear modelling; Usui’s model; Response Surface Methodology; thermal fatigue cracking; flank wear;

    Abstract : The experimental approach has long been the main method to investigate the responses associated with metal cutting process such as cutting forces and temperatures and also to optimise the machining operations to accomplish higher productivity. In recent years, with advances in computing power of computers along with development of robust numerical methods such as Finite Element Method (FEM), it has been possible to simulate different machining process under operational conditions.
