    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Microfluidics; Ultrasound; Multinode; Cell Sorting; Particle Positioning; Cytometry; Lab-on-a-Chip; µTAS; Binary Separation; Acoustic Barriers; Acoustic Particle Manipulation; Acoustic Standing Waves; Blood Separation; Milk Analysis;

    Abstract : Popular Abstract in Swedish Vilken musiksmak har blodceller? Forskningen som presenteras i denna avhandling undersöker och drar nytta av hur olika celler uppför sig när de utsätts för ljud. På samma sätt som människor uppskattar olika sorters musik så reagerar olika typer av celler annorlunda beroende på vilka ljud de utsätts för. READ MORE

  2. 2. Remote Acoustic Characterization of Thin Sheets

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Etienne Mfoumou; Blekinge Tekniska Högskola.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remote acoustic excitation; material characterization; acoustic NDT; vibration-based technique; sheet material evaluation; fracture toughness.;

    Abstract : There is a need to monitor the existence and effects of damage in structural materials. Aircraft components provide a much publicized example, but the need exists in a variety of other structures, such as layered materials used in food packaging industries. READ MORE

  3. 3. Acoustic separation of submicron particles in gaseous flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ramin Imani Jajarmi; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic; submicron particles; gaseous flows; separation; Teknisk mekanik; Engineering Mechanics;

    Abstract : The separation of submicron particles suspended in gaseous flows is a problem of great importance and is the subject of sustained research efforts. This is motivated by several challenges presented by modern science and technology requiring high separation efficiencies for submicron particles.

    Abstract : This thesis investigates structure-acoustic problems, which involve a flexible structure coupled to an enclosed acoustic fluid. In the literature, this type of problem is usually referred to as vibroacoustic problems or structure-acoustic problems with fluid interaction. The thesis consists of two parts. READ MORE

  5. 5. Acoustic Trapping in Biomedical Research

    University dissertation from Division of Structural Mechanics LTH, Lund University Box 118 221 00 Lund Sweden

    Abstract : Popular Abstract in Swedish I naturen finns en närmast oändlig variation av biologiska partiklar i storleksordningen 100 nanometer till 10 mikrometer. Bland dessa kan man bland annat finna; eukaryota celler som genom ordnad samverkan bygger upp flercelliga organismer, prokaryota celler vilka lever som solitära organismer såsom olika bakterier eller jästsvamp, och viruspartiklar vilka likt parasiter specialiserat sig på att få större celler att reproducera deras DNA.
