    Abstract : During the last decade, ultrasonic manipulation has matured into an important tool with a wide range of applications, from fundamental cell biological research to clinical and industrial implementations. The contactless nature of ultrasound makes it possible to manipulate living cells in a gentle way, e.g. READ MORE

  4. 2. Ultrasonic Handling of Living Cells in Microfluidic Systems

    Author : Jessica Svennebring; Martin Wiklund; Hans Hertz; Martyn Hill; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineering; Bioteknik;

    Abstract : Microfluidic chips have become a powerful tool in research where biological cells are processed and/or analyzed. One method for contactless cell manipulation in microfluidic chips that has gained an increasing amount of attention the last decade is ultrasonic standing wave (USW) technology. READ MORE

  5. 3. Installation effects and self diagnostics for ultrasonic flow measurement

    Author : Carl Carlander; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : In the district heating industry, heat meters, consisting among other things of a flow meter, are used for billing purpose. The district heating industry desires accurate and low cost flow measurements. There are mainly two reasons. An under estimation of the flow rate leads to a loss of income for the district heating industry. READ MORE

  6. 4. On the analysis of cast structure and its changes during hot working of forging ingots

    Author : Jan Sarnet; Hasse Fredriksson; Alec Mitchell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Abstract : Forging ingots are hot worked to consolidate structural imperfections and refine the microstructure. Possible imperfections are segregations, porosities, cracks, and inclusions. In this thesis, techniques and methods for the characterisation of behaviour and properties of ingots and forgings. READ MORE

  7. 5. Acoustical experiments on the non-linear and non-equilibrium behavior of rocks

    Author : Babak Khodabandeloo; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The study of dynamic behavior of non-perfect materials, such as rocks, is a rich topic for developing sensitive material evaluation and damage detection techniques. It has extensive applications in a variety of fields such as Physics, Geology, and Aerospace, Mechanical, Civil, Petroleum, and Material Engineering. READ MORE
