  1. 1. Theory and use of chaotic oscillators in electronic communication systems

    Författare :Anders J Johansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chaos; complexity theory; random numbers; Chaotic oscillators;

    Sammanfattning : 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.. LÄS MER

  2. 2. Wireless Communication with Medical Implants: Antennas and Propagation

    Författare :Anders J Johansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical implant communication; electromagnetic propagation; biomedical telemetry; antennas in matter; MICS; Electronics; Elektronik;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Transfer RNA (tRNA) genes are transcribed by RNA polymerase III as precursors that undergo multiple processing steps to form mature tRNAs. These steps include processing of the 5’ leader and 3’ trailer sequences, addition of a 3’ CCA tail, removal of introns, and formation of modified nucleosides. LÄS MER
