  1. 1. Simulating MPC Controlled Lime Injection for the Flue-gas Treatment at Fortum's Thermal Power Plant

    University essay from KTH/Reglerteknik

    Author : Joacim Sundberg; [2015]
    Keywords : ;

    Abstract : The aim of this thesis is to investigate the possibility to improve the separation ofHCl and SO2 in the dry ue-gas treatment for boiler #3 at Fortum's thermal powerplant in Hogdalen; by using a model predictive control instead of a PID controllerto govern the slaked lime injection.To achieve this an ARMAX model was derived using MATLAB's System Identication Toolbox and measurements of the incoming and outgoing levels of HCl,SO2 and the speed of the injection motor.

  2. 2. Methane Oxidation in three Swedish Forest Soils

    University essay from SLU/Dept. of Soil and Environment

    Author : Kwesi Idun Osam; [2012]
    Keywords : methane; oxidation; forest; soils; methanotrophs; multi-carbon compounds; consumption;

    Abstract : Aerated soils are the largest sinks of atmospheric methane on the Earth’s surface. Methane removal from the atmosphere is performed through oxidation by microorganisms (methaneoxidising bacteria) in the soil. READ MORE

  3. 3. State as a Service : Towards Stateful Cloud Services

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Ahmadullah Alnoor; [2012]
    Keywords : ;

    Abstract : Cloud ERP or Enterprise Resource Planning (ERP) as a Cloud Service delivers value by reducing initial and long term operating costs since infrastructure, platform and (certain) application management tasks are delegated to a specialist provider. Questions present at intersection of the ERP challenge landscape and the Cloud Computing opportunity horizon include characterization of Cloud friendly ERP modules and adaptation of stateful (on-premises ERP) components to a stateless platform.

  4. 4. Accumulation of carbon and nitrogen in Swedish forest soils over stand age

    University essay from SLU/Dept. of Soil and Environment

    Author : Petros Georgiadis; [2011]
    Keywords : Soil Organic Carbon; Nitrogen; Decomposition; Stand age; Litter-fall;

    Abstract : Forest disturbance and harvesting regimes may affect the carbon (C)amounts stored in forest soils. The amount of soil C decreases after harvest and recovers gradually. Earlier chronosequence studies have suggested 50%decrease of the forest floor within the first 15 years after harvest. READ MORE

  5. 5. Microscopic black holes

    University essay from Lunds universitet/Fysiska institutionen

    Author : Jakob Merouani; [2011]
    Keywords : Physics and Astronomy;

    Abstract : In this report I will write about the possibility of black hole creation when introducing the theory of extra spatial dimensions in the visible (3+1) dimensional universe. First I will give a little background on the postulation of black hole formation and talk about what properties black holes have in general, for example the event horizon, singularity and the formation of the black hole is discussed.
