  1. 11. Tactile sensing of prostate cancer : a resonance sensor method evaluated using human prostate tissue in vitro

    Author : Ville Jalkanen; Olof Lindahl; Britt Andersson; Tomas Jansson; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tactile resonance sensor; prostate tissue; prostate cancer; stiffness; density; elastic; variations; tissue histology; Medical engineering; Medicinsk teknik;

    Abstract : Prostate cancer is the most frequent type of cancer in men in Europe and the USA. The methods presently used to detect and diagnose prostate cancer are inexact, and new techniques are needed. READ MORE

    Abstract : The thesis concerns polyelectrolyte gels in contact with oppositely charged proteins and surfactant micelles, and includes of four papers (I-IV). In paper I confocal Raman spectroscopy was introduced as a method to trace micelles and investigate the structure of gel-surfactant complexes, in phase separated gel spheres. READ MORE

  3. 13. Estimation of state and identification of complex modulus based on measurements om a bar traversed by waves

    Author : Lars Hillström; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Wave; extensional; flexural; bar; rod; beam; elastic; viscoelastic; complex modulus; non-parametric; parametric; standard deviation; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid Mechanics; hållfasthetslära;

    Abstract : Estimation of state and identification of complex modulus based on measurements on non-uniform rods and beams have been studied theoretically and experimentally. Two principal cases were studied. In the first case, the material properties are fully known and the state at a section is to be estimated. READ MORE

  4. 14. Elastic properties of suspended graphene

    Author : Daniel Midtvedt; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns describing the mechanical properties of the two dimensional material graphene by continuum elasticity theory. In particular, Nano ElectroMechanical Systems (NEMS) where part of the graphene sheet is made suspended, are considered. READ MORE

  5. 15. Contributions to the Modeling and Simulation of Mechanical Systems with Detailed Contact Analyses

    Author : Iakov Nakhimovski; Dag Fritzson; Peter Fritzson; Claus Führer; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; multibody dynamics simulation; contacts; flexibility; elastic; floating reference frame; hybrid parallel; co-simulation; TLM; Computer science; Datavetenskap;

    Abstract : The motivation for this thesis was the need for further development of multibody dynamics simulation packages focused on detailed contact analysis. The thesis makes contributions in three different areas:Part I summarizes the equations, algorithms and design decisions necessary for dynamics simulation of flexible bodies with moving contacts.
