  1. 1. Mille-feuille Filter : A Non-woven Nano-cellulose Based Virus Removal Filter for Bioprocessing

    Författare :Simon Gustafsson; Albert Mihranyan; Jonas Lindh; Kurt Brorson; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; virus filtration; mille-feuille; downstream; nanocellulose; protein throughput; protein recovery; LRV; MVM; Cladophora; non-woven filter;

    Sammanfattning : Virus removal filters, produced from synthetic surface-modified polymers or regenerated cellulose by phase inversion, are vital to the production of therapeutic proteins such as monoclonal antibodies and plasma proteins. Use of these filters is also one of the most expensive purification steps in the downstream processing of proteins due to high sales price and being limited to a single use. LÄS MER

  3. 3. Functional Hodrick-Prescott Filter

    Författare :Hiba Nassar; Astrid Hilbert; Alexander Meister; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Inverse problems; adaptive estimation; Hodrick-Prescott filter; smoothing; trend extraction; Gaussian measures on a Hilbert space.; Mathematics; Matematik;

    Sammanfattning : The study of functional data analysis is motivated by their applications in various fields of statistical estimation and statistical inverse problems.In this thesis we propose a functional Hodrick-Prescott filter. This filter is applied to functional data which take values in an infinite dimensional separable Hilbert space. LÄS MER

  4. 4. Processing Aspects for Improving Mechanical Properties in Aluminium Castings

    Författare :Jonas Bäckman; Linköpings universitet; []
    Nyckelord :Aluminium; microstructure; mechanical properties; gradient solidification; mould filling; filter; filter parameter; casting simulation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The relation between the process and mechanical properties in aluminium alloys for castings has been examined. The relation was hard to define since the spread in data was severe due to defects created in the casting process. To avoid such defects a gradient solidification equipment was built. LÄS MER

  5. 5. Estimation of Nonlinear Dynamic Systems : Theory and Applications

    Författare :Thomas B. Schön; Fredrik Gustafsson; Simon Godsill; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; Automatic control; Reglerteknik;

    Sammanfattning : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. LÄS MER
