  2. 1. On an Efficient Method fo Time-Domain Computational Aeroelasticity

    Author : David Eller; Ulf Ringertz; Paolo Mantegazza; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeroelasticity; unsteady aerodynamics; boundary element method; multidisciplinary simulation; Vehicle engineering; Farkostteknik;

    Abstract : The present thesis summarizes work on developing a method for unsteady aerodynamic analysis primarily for aeroelastic simulations. In contrast to widely used prediction tools based on frequency-domain representations, the current approach aims to provide a time-domain simulation capability which can be readily integrated with possibly nonlinear structural and control system models.

  4. 2. Design and fabrication of hidden hinge monocrystalline silicon micromirrors for maskless lithography

    Author : Martin Bring; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isotropic etching; LOCOS; micromirror; maskless lithography; chevron notch; low temperature transfer bonding; fracture toughness;

    Abstract : Micromirror-based maskless lithography has recently received attention as an attractive candidate to tackle challenges associated with the continued de-vice scaling in the semiconductor industry. The micromirrors work by diffrac-tion and the requirements on planarity are very tough, e.g. peak-to-valley dif-ferences of a few nanometers. READ MORE

  5. 3. A simple model of the mechanics of trombone playing

    Author : Gitte Ekdahl; KTH; []
    Keywords : ;

    Abstract : To study human motion in general, the motion when playingthe trombone has been examined. This makes it possible to workwith a simple mechanical model and thus get results that areeasier to interpret. Calculations from the model have beencompared to measurements from experiments.

  6. 4. Wafer-level 3-D CMOS Integration of Very-large-scale Silicon Micromirror Arrays and Room-temperature Wafer-level Packaging

    Author : Martin Lapisa; Frank Niklaus; Olav Solgaard; KTH; []
    Keywords : ;

    Abstract : This thesis describes the development of wafer-level fabrication and packaging methods for micro-electromechanical (MEMS) devices, based on wafer-bonding.The first part of the thesis is addressing the development of a wafer-level technology that allows the use of high performance materials, such as monocrystalline silicon, for MEMS devices that are closely integrated on top of sensitive integrated circuits substrates.

  7. 5. Mechanics of Nanocellulose Foams : Experimental and Numerical Studies

    Author : Prashanth Srinivasa; Artem Kulachenko; Laurent Orgéas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Nanofibrillär cellulosa (NFC) skum är en intressant klass av cellulära material med möjliga applikationer som sträcker sig från fordonsindustrin till biomedicin då det har unika och önskvärda mekaniska egenskaper. I ljuset av de senaste framstegen inom framställning av skum förutspås det tillämpas inom en rad olika områden, inklusive områden där dess mekaniska egenskaper är viktiga. READ MORE
