  3. 2. Oxygen-reducing enzymes in coatings and films for active packaging

    Författare :Kristin Johansson; Lars Järnström; Caisa Johansson; Leif J. Jönsson; Jose M. Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active packaging; food packaging; oxygen scavengers; oxygen-reducing enzymes; dispersion coating; biopolymers; Chemical Engineering; Kemiteknik;

    Sammanfattning : Oxygen scavengers are used in active packages to protect the food against deteriorative oxidation processes. The aim of this work was to investigate the possibilities to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. LÄS MER

  4. 3. 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

  5. 4. 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
