    Sammanfattning : Molecule detection is a workhorse in life sciences and medicine, for example in cancer diagnosis and virus and bacterial detection. DNA analysis can provide vital information about the state of a host organism and its medical and health condition. LÄS MER

  5. 4. Ultrasonic measurement principles : modeling, identification, and parameter estimation

    Författare :Jesper Martinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis presents contributions within the fields of ultrasonic modeling and measurement technology, with focus on solutions to difficult modeling and measurement problems. The work is divided into two categories: 1) processing of measurements obtained under non-ideal conditions, such as unsynchronized, distorted, and superimposed signals; 2) estimating acoustic models and parameters from materials, fluids, fluid mixtures, and thin-layered structures.
