  1. 1. Upflow anaerobic sludge blanket reactor : modelling

    Författare :Raul Rodriguez; Luis Moreno; Olle Wahlberg; Gunno Renman; KTH; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; Chemistry; Kemi;

    Sammanfattning : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

  3. 2. Performance Modelling and Simulation of Service Chains for Telecom Clouds

    Författare :Michel Gokan Khan; Javid Taheri; Andreas Kassler; Johan Tordsson; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Performance Modelling; Performance Optimization; Performance Simulation; Network Function Virtualization; Cloud Native Computing; Computer Science; Datavetenskap;

    Sammanfattning : New services and ever increasing traffic volumes require the next generation of mobile networks, e.g. 5G, to be much more flexible and scalable. The primary enabler for its flexibility is transforming network functions from proprietary hardware to software using modern virtualization technologies, paving the way of virtual network functions (VNF).

  4. 3. Lifetime Performance Assessment of Thermal Systems : Studies on Building, Solar and Disctrict Heating Applications

    Författare :Bojan Stojanovic; Christer Sjöström; Per Jostein Hovde; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lifetime performance; degradation; assessment; modelling; field exposure; thermal components and system; Building engineering; Byggnadsteknik; Materials science; Teknisk materialvetenskap; lifetime performance; thermal components and systems;

    Sammanfattning : The main questions today concerning thermal systems are their economical and environmental impacts. These entities are generally, at present, assessed on the basis of operation performances of newly installed/designed systems, during an assumed lifetime period. LÄS MER

  5. 4. Cone Crusher Performance

    Författare :Magnus Evertsson; Chalmers University of Technology; []
    Nyckelord :mining; size-reduction; particle size; crushing; comminution; modelling; simulation; aggregates;

    Sammanfattning : Cone crushers are used by both the aggregate producing and the mining industry. Both industries are interested in increasing the product quality while at the same time lowering the production costs. Prediction of crusher performance has been focused on, since crushing is a vital process for both industries. LÄS MER

  7. 5. Pull based production systems : performance, modelling and analysis

    Författare :Jan-Arne Pettersen; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Logistics; Industriell logistik;

    Sammanfattning : This doctoral thesis addresses performances, modelling and analyses of pull based production systems. The thesis consists of four main parts: a literature review, a comparison study of Kanban and CONWIP, an industrial practical case study, and the development of a new tool used for presentation and analysis of simulated performance results.
