  1. 1. Electropermutation assisted by ion-exchange textile removal of nitrate from drinking water

    Detta är en avhandling från Stockholm : KTH

    Författare :Carl-Ola Danielsson; KTH.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion-exchange textile; Ion-exchange membrane; Electropermutation; Electroextraction; Electrodialysis; Electrodeionisation; Modeling; Conducting spacer; Nitrate removal; Water treatment; Water dissociation; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Sammanfattning : Increased levels of nitrate in ground water have made many wells unsuitable as sources for drinking water. In this thesis an ion-exchang eassisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. LÄS MER

  3. 3. Modification of Float Glass Surfaces by Ion Exchange

    Detta är en avhandling från Växjö, Kalmar : Linnaeus University Press

    Författare :Stefan Karlsson; Bo Jonson; Helmut Schaeffer; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion exchange; float glass; surface modification; surface colour; flexural strength; Glasteknologi; Glass Technology;

    Sammanfattning : Glass is a common material in each person’s life, e.g. drinking vessels, windows, displays, insulation and optical fibres. By modifying the glass surface it is possible to change the performance of the entire glass object, generally known as Surface Engineering. LÄS MER

  4. 4. Analysis and Optimisation of Distributed Embedded Systems with Heterogeneous Scheduling Policies

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Traian Pop; Petru Ion Eles; Zebo Peng; Luis Almeida; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed embedded systems; Real-time analysis; Scheduling; Design optimisation; FlexRay; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Data- och systemvetenskap;

    Sammanfattning : The growing amount and diversity of functions to be implemented by the current and future embedded applications (like, for example, in automotive electronics) have shown that, in many cases, time-triggered and event-triggered functions have to coexist on the computing nodes and to interact over the communication infrastructure. When time-triggered and event-triggered activities have to share the same processing node, a natural way for the execution support can be provided through a hierarchical scheduler. LÄS MER

  5. 5. Aromatic Polymers Functionalized with Anionic and Cationic Groups for Ion Exchange Membranes

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Annika Weiber; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion exchange membranes; fuel cells; polycondensation; local ion density; poly arylene ether sulfone s;

    Sammanfattning : Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. LÄS MER
