  2. 21. On Modeling the Dynamics of Fixed Biofilm Reactors. With focus on nitrifying trickling filters

    Author : Torsten Wik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operation; transfer functions; biofilm reactors; adsorption; dormancy; modeling; dynamics; nitrification;

    Abstract : Fixed biofilms, which are matrix-enclosed populations of organisms attached to solid surfaces, are increasingly used in environmental biotechnology processes, such as the treatment of potable water and wastewater. This thesis aims to give some insight into the dynamic modeling of biofilms and fixed biofilm reactors, with a focus on nitrifying trickling filters (NTFs) for the treatment of wastewater. READ MORE

  4. 22. MEMS Interfaces for Bioanalysis Systems

    Author : Thomas Frisk; Göran Stemme; Andreas Hierlemann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfluidic interfacing; microfluidics; µTAS; sample transfer; biosensor; electronic nose; surface tension; quartz crystal microbalance; QCM; narcotics detection; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

    Abstract : This thesis deals with various aspects of using open microfluidic interfaces. Three specific areas of application are studied. The first is air-to-liquid interfacing in biosensors with possibilities for component inte­gration. A micromachined interface for airborne sample-to-liquid and droplet-to-liquid adsorption is discussed. READ MORE

  5. 23. On matrix-driven failure in unidirectional NCF composites - A theoretical and experimental study

    Author : Dennis Wilhelmsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NCF composite; aerospace; compressive testing; compressive failure;

    Abstract : With ever increasing traffic levels, the civil aircraft industry is in constant need of new technologies to make air travel environmentally sustainable. One such technology is light materials to reduce the energy consumption in flight. READ MORE

  6. 24. On Transfer Functions for Power Quality Studies in Wind Power and Solar PV Plants

    Author : Daphne Schwanz; Math Bollen; Anders Larsson; Jovica Milanovic; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

    Abstract : As part of the decarbonisation of the energy system, wind and solar power are expected to play an important role. However, together with their growth, new challenges appear in the electric power system; this requires further research, development, and often studies before connection is possible. READ MORE
