  1. 1. Experiments on optimal maintenance operations with emphasis on end-of-contract constraints

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Sebastian Ahlman; Philip Nilsson; Tanha Kamran; [2019-06-18]
    Keywords : ;

    Abstract : To minimize the unnecessary costs that arise when machines or other objects fail, perhapsneeding to be replaced during less than ideal occasions through what is knownas reactive maintenance, a more active maintenance policy through which objects arecontinuously maintained in a preventative manner based on life expectancy or from acost-perspective, is preferred. Mathematical models can be advantageous to utilize whenscheduling these maintenance occasion. READ MORE

  2. 2. Monte Carlo Simulations of Bowing Effects Using Realistic Fuel Data in Nuclear Fuel Assemblies

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Westlund; [2019]
    Keywords : bowing effects; fuel assembly perturbations; nuclear; serpent; monte carlo;

    Abstract : Deformations of nuclear fuel assemblies have been observed in nuclear power plants since the mid-90s. Such deformations are generally called bowing effects. READ MORE

  3. 3. Wind Forecasts Using Large Eddy Simulations for Stratospheric Balloon Applications

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Ludvig Sjöberg; [2019]
    Keywords : Weather Research and Forecasting Model; Large Eddy Simulation; Microscale Meteorology;

    Abstract : The launch of large stratospheric balloons is highly dependant on the meteorological conditions at ground level, including wind speed. The balloon launch base Esrange Space Center in northern Sweden currently uses forecasts delivered through the Swedish Meteorological and Hydrological Institute to predict opportunities for balloon launches.

  4. 4. Study on future storm surge around Suo-nada Sea

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Ayano Sonoda; [2019]
    Keywords : storm surge; Suo-nada Sea; numerical simulation; FVCOM; Technology and Engineering;

    Abstract : Japan lies on an area frequently hit by typhoons while city functions are clustered along the flat coastal areas, hence Japan has experienced lots of storm surge disasters up to the present. Coastal areas along the Suo-nada Sea also have the vulnerability against storm surge and in the past Typhoon 18 in 1999, Typhoon 16 and 18 in 2004 made remarkable damages in the areas. READ MORE

  5. 5. Production optimization for district heating : Short-term planning of district heating grid in Gävle, Sweden

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Nicolas Lindgren; Karl Brogren; [2019]
    Keywords : Short-term planning; Optimization; District heating; Linear programming; Mixed integer non-linear programming; Branch and bound; Heat storage; MATLAB; TOMLAB;

    Abstract : Energy systems with a high portion of renewable energy from wind and solar power can suffer from fluctuations in production due to weak winds or cloudy weather, which may affect the electricity price. When producing heat and power in a combined heat and power plant, an additional heat storage tank can be used to store the heat surplus which is obtained when the power production is high, and the heat demand is low.
