  2. 6. Bacterial identification by the 16S rRNA gene

    Author : Tobias Olofsson; Avdelningen för medicinsk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Naturvetenskap; Natural science; mykologi; virologi; Mikrobiologi; mycology; virology; bacteriology; 16S rRNA; Microbiology; Identification; Bacteria; bakteriologi;

    Abstract : The identification and classification of bacteria was initially performed with morphological methods applied on cultivated bacteria. It was not until the mid 1970s, when sequences of ribosomal RNA were discovered to be useful for bacterial evolution, that a new era started. This method showed to be far more accurate for bacterial identification. READ MORE

  4. 7. Inverse Identification of Dynamic Wheel-rail Contact Forces

    Author : Hamed Ronasi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse problems; sensitivity; optimization; regularization; railway mechanics; input estimation; load identification;

    Abstract : Accurate evaluation of contact forces between wheel and rail is essential in the assessmentof vehicle performance and to predict consequences of dynamic vehicle-track interaction.As the contact forces can not be measured directly in the field, one common approachis to measure the strain or acceleration at various positions on a wheel or wheel axle.

  5. 8. Towards the Identification of Wheel-Rail Contact Forces

    Author : Hamed Ronasi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; regularization; optimization; input estimation; load identification; inverse problems;

    Abstract : The accurate determination of the contact forces between rail and wheel is essential inthe analysis of different kinds of rolling contact fatigue. As the contact forces cannot bemeasured directly in the field, one approach is to measure the strain at certain positionsof an instrumented wheel. READ MORE

  6. 9. Identification, Diagnosis, and Control of a Flexible Robot Arm

    Author : Måns Östring; Svante Gunnarsson; Mikael Norrlöf; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Identification; Robot; Flexible; Diagnosis; Control; LQG; Recursive;

    Abstract : The most important factors in manufacturing are quality, cost, and productivity. The trend is towards lighter robots with increased mechanical flexibilities, and therefore there is a need to include the flexibilities in the robot models to obtain good performance of the robot.

  7. 10. Identification of Viscoelastic Materials by Use of Wave Propagation Methods

    Author : Saed Mousavi; Bengt Lundberg; Urmas Valdek; Janne Färm; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Identification; Viscoelastic; Complex modulus; Complex Poisson s ratio; wave; Impact; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Complex moduli and Poisson’s ratio have been estimated using extensional and torsional wave experiments. The data were used for assessment of linearity and isotropy of two polymers, polymethyl methacrylate (PMMA) and polypropylene (PP). The responses of both materials were found to be close to linear and isotropic. READ MORE
