  1. 11. Dynamic response reconstruction using passive components

    Author : Anders Johansson; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

    Abstract : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. READ MORE

  3. 13. Theory and use of chaotic oscillators in electronic communication systems

    University dissertation from Lund University

    Author : Anders J Johansson; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chaos; complexity theory; random numbers; Chaotic oscillators;

    Abstract : The theory and applications of chaotic oscillators in electronic commuication are investigated. A method of random number generation utilising a chaotic double scroll oscillator is proposed and evaluated. The theoretical limits of the randomness of the method is analysed.. READ MORE

  4. 14. Wireless Communication with Medical Implants: Antennas and Propagation

    University dissertation from Department of Electroscience, Lund University

    Author : Anders J Johansson; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical implant communication; electromagnetic propagation; biomedical telemetry; antennas in matter; MICS; Electronics; Elektronik;

    Abstract : With the increased sophistication of medical implants, there is a growing need for flexible high-speed communication with the implant from outside the body. Today the communication is done by an inductive link between the implant and an external coil at a low carrier frequency. READ MORE

  5. 15. MEASUREMENT OF PARTICULATES EMITTED FROM SGDI ENGINES

    University dissertation from Department of Electroscience, Lund University

    Author : Anders Johansson; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis discusses particulate emissions from spray guided, gasoline, direct-injected (GDI) engines. The aim was to measure solid particulates without the influence of volatiles. Therefore, two sampling systems were developed for sampling either low or high particulate content. READ MORE
