    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial intelligence AI ; Life cycle cost LCC ; Machine learning ML ; Multi-objective genetic algorithm MOGA ; Risk-based life cycle cost LCC ; Tunnel fans; Two-level system; Operation and Maintenance Engineering; Drift och underhållsteknik;

    Sammanfattning : Artificial intelligence (AI) is one of the fields in science and engineering and encompasses a wide variety of subfields, ranging from general areas (learning and perception) to specific topics, such as mathematical theorems. AI and, specifically, multi-objective genetic algorithms (MOGAs) for risk-based life cycle cost (LCC) analysis should be performed to estimate the optimal replacement time of tunnel fan systems, with a view towards reducing the ownership cost and the risk cost and increasing company profitability from an economic point of view.

  5. 19. A Thermoeconomic Evaluation of CO2 Capture with Focus on Gas Turbine-Based Power Plants

    Författare :Björn Fredriksson Möller; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; climate change; optimisation; genetic algorithms; applied thermodynamics; Thermal engineering; AZEP; GTPOM; gas turbine; CO2 capture; thermoeconomy; termodynamik;

    Sammanfattning : The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. LÄS MER

  7. 20. Integrated brake control : downhill driving strategies

    Författare :Peter Lingman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport efficiency; heavy duty trucks; road slope estimation; cruise controller; retardation economy; foundation brakes; mass estimation; brake heat fading; Auxilary brakes; downhill driving strategies; component wear;

    Sammanfattning : In this thesis, downhill driving strategies that co–ordinate the different brake actuators in heavy duty vehicles have been developed. As a starting point, the vehicle features affected by the retardation system are investigated. LÄS MER
