  1. 1. Upflow anaerobic sludge blanket reactor modelling

    University dissertation from Stockholm : US-AB

    Author : Raul Rodriguez; KTH.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; MEDICINE Chemistry; MEDICIN Kemi;

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

    University dissertation from Stockholm : KTH

    Author : Bojan Stojanovic; Högskolan i Gävle.; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; lifetime performance; degradation; assessment; modelling; field exposure; thermal components and systems; Lifetime performance; thermal components and system;

    Abstract : 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. READ MORE

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jan-Arne Pettersen; Luleå tekniska universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Logistics; Industriell logistik;

    Abstract : 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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Emil Nilsson; Patrik Rohdin; Maria Andersson; Mathias Cehlin; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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

    University dissertation from Stockholm : US-AB

    Author : Abubeker Worake Ahmed; KTH.; Statens väg- och transportforskningsinstitut.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science; Civil and Architectural Engineering; Byggvetenskap; Flexible Pavement; Pavement Performance Models; Multilayer Elastic Theory; Linear Viscoelasticity; Rutting; Accelerated Pavement Testing; Heavy Vehicle Simulator; Road: Pavement design; Road: Pavement design; 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;

    Abstract : 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.
