  1. 1. Upflow anaerobic sludge blanket reactor modelling

    Detta är en avhandling från Stockholm : US-AB

    Författare :Raul Rodriguez; Luis Moreno; Olle Wahlberg; Gunno Renman; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; MEDICINE Chemistry; MEDICIN 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.

  2. 2. Cone Crusher Performance

    Detta är en avhandling från Stockholm : US-AB

    Författare :Magnus Evertsson; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  3. 3. Pull based production systems performance, modelling and analysis

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jan-Arne Pettersen; [2010]
    Nyckelord :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.

  4. 4. Borehole Thermal Energy Storage Systems for Storage of Industrial Excess Heat Performance Evaluation and Modelling

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Emil Nilsson; Patrik Rohdin; Maria Andersson; Mathias Cehlin; [2020]

    Sammanfattning : Improving industrial energy efficiency is considered an important factor in reducing carbon dioxide emissions and counteract climate change. For many industrial companies in cold climates, heat generated at the site in summer will not be needed to fulfil the site heat demand during this time, and is thus removed to the outdoor air.

  5. 5. Mechanistic-Empirical Modelling of Flexible Pavement Performance : Verifications Using APT Measurements

    Detta är en avhandling från Stockholm : US-AB

    Författare :Abubeker W. Ahmed; Sigurdur Erlingsson; Hervè Di Benedetto; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance; Deformation; Model not math ; Rutting wheel ; Viscoelasticity; Elasticity; Axle load; Flexible pavement; Laboratory not an organization ; Test; Thesis; Heavy vehicle simulator; Wheel tracking test; Road: Pavement design; Road: Pavement design;

    Sammanfattning : Mechanistic-Empirical  (M-E)  pavement  design  procedures  are  composed  of  a  reliable  response model to estimate the state of stress in the pavement and distress models in order to predict the different types of pavement distresses due to the prevailing traffic and environmental conditions. One of the main objectives of this study was to develop a response model based on multilayer elastic  theory   (MLET)  with  improved  computational  performance  by   optimizing  the   time consuming parts of the MLET processes.
