  2. 2. Inductively Coupled Plasma Spectrometry for Speciation Analysis Development and Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Niklas Forsgard; Uppsala universitet.; [2007]
    Nyckelord :Analytical chemistry; Speciation analysis; Atomic emission spectrometry AES ; Mass spectrometry MS ; Inductively coupled plasma ICP ; Liquid Chromatography LC ; on-line sample pre-treatment; Organic phosphour; Siderophores; Slurry nebulization; matrix effects; Analytisk kemi;

    Sammanfattning : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.

  3. 3. Numerical Analysis of Evolution Problems in Multiphysics

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola

    Författare :Anna Persson; Göteborgs universitet.; Gothenburg University.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Regularity; generalized finite element; localized orthogonal decomposition; multiscale finite element method; Thermoelasticity; Riccati equations; thermistor; linear elasticity; Joule heating; parabolic equations; regularity; multiscale; finite element method;

    Sammanfattning : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.

  4. 4. Error analysis of summation-by-parts formulations Dispersion, transmission and accuracy

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Viktor Linders; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis we consider errors arising from finite difference operators on summation-by-parts (SBP) form, used in the discretisation of partial differential equations. The SBP operators are augmented with simultaneous-approximation-terms (SATs) to weakly impose boundary conditions. LÄS MER

  5. 5. Analysis of Fatigue Characteristics in Mooring Lines and Low Voltage Cables for Wave Energy Converters

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Shun-Han Yang; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave energy converter; de-coupled analysis; power cable; fatigue; dynamic cable; heaving point absorber; mooring line; coupled analysis; power absorption; marine biofouling effect on absorbed power; low voltage cable; catenary mooring chain; marine biofouling effect on fatigue;

    Sammanfattning : To reduce both carbon emission and fossil fuel consumption, there is a pressing need for the exploitation of renewable sources of energy such as biomass, hydropower, solar power, waves, and wind. This thesis addresses the application of wave energy, which has a large potential to contribute to the world’s renewable emission-free energy supply. LÄS MER
