  1. 16. Washing Machine Design Optimization Based on Dynamics Modeling

    Author : Thomas Nygårds; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experiments; Multiobjective Optimization; Modeling; Vibration dynamics; Washing machine; Suspensions; Semi-active control.; Automatic balancing;

    Abstract : The spinning process in a washing machine is a source of undesired vibrations and noise and may cause discomfort both to the user as well as for the machine itself due to vibrations which have impact on system lifetime, reliability of operation and capacity.The aim of this thesis is to develop mathematical and computational models of a washing machine of modern type and use these models for dynamics analysis and in optimization routines to make improvements of the machine mechanical design.

  2. 17. Multiscale methods for simulation of paper making

    Author : Gustav Kettil; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paper making; Numerical upscaling; Lay down simulations; Virtual paper sheets; Fiber network model; Forming fabric flow; Fiber suspension flow; Fiber-fiber interaction; Multiscale methods; Fluid structure interaction;

    Abstract : In this work, multiscale methods for simulation of paper making are developed. The emphasis is on simulation of the paper forming process and simulation of the mechanical properties of paper sheets. To simulate paper forming, a novel fiber-fiber interaction method is proposed.

  3. 18. Unveiling catalytic species in suspension/solution-based reactions by in situ X-ray absorption spectroscopy

    Author : Ning Yuan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The palladium (Pd) and ruthenium (Ru) species in several attractive catalysts have been probed using X-ray absorption spectroscopy (XAS). The study of catalyst evolution in suspension- and solution-based reactions was the primary aim. It was achieved by performing in situ XAS experiments on Pd and Ru over the course of the reactions.

  4. 19. Saliva: a cell suspension of epithelial cells harboring the antimicrobial peptide LL-37 and the growth factor EGF

    Author : Alexandra Aidoukovitch; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defense peptides; EGF; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defence peptides; EGF;

    Abstract : Saliva plays a crucial role in maintaining oral health through its physical and chemical properties that provide various protective functions. One of its essential components is the human host defense peptide LL-37, which is produced by immune cells and epithelial cells, and participates in the first line of defense against pathogens.

  5. 20. Simulation of collective phenomena in microswimmer suspensions

    Author : Dora Bardfalvy; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Collective motion is ubiquitous in biological and synthetic systems across manylength- and timescales. On the macroscopic scale, examples include schools of fish, herds of sheep and flocks of birds. On the microscopic scale, bacteria, algae and synthetic self-propelled particles exhibit a range of collective phenomena. READ MORE
