  5. 4. Quantification and Implementation of Structural Damping in MBS Flexible Bodies

    University essay from Lunds universitet/Mekanik

    Author : Anton Flink; [2015]
    Keywords : Technology and Engineering;

    Abstract : In multi body simulation (MBS) using flexible bodies, damping is an important model input to be able to predict the response of a structure with sufficient precision. The purpose of this thesis has been to estimate the structural damping of an experimental setup and implement the estimated damping into MBS-models of the setup. READ MORE

  6. 5. Evaluation of the performance of a wireless magnetoelastic pH-sensor in rumen environment

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Mohammad Oli Ullah; [2013]
    Keywords : SARA; pH; Rumen; Fistulated animal; Magnetoelastic sensor;

    Abstract : Sub-acute rumen acidosis (SARA) is a problem with major economic importance in dairy production. The definition of SARA is a low pH (< 5.3-5.5) in the rumen during several hours in the day. READ MORE
