  1. 1. A Nonlinear Optimization Approach to H2-Optimal Modeling and Control

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Daniel Petersson; Johan Löfberg; Lennart Ljung; Roland Toth; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model reduction; LPV system; linear parameter varying; controller; control synthesis; H2; H2-norm; nonlinear optimization;

    Abstract : Mathematical models of physical systems are pervasive in engineering. These models can be used to analyze properties of the system, to simulate the system, or synthesize controllers. However, many of these models are too complex or too large for standard analysis and synthesis methods to be applicable. READ MORE

    Abstract : Gasification of biomass and waste is promising for reducing the use of fossil fuels. While the operation conditions of superheaters and gas coolers in the gasifier are restricted by gas-side corrosion, scientific investigations are very scarce in this field. READ MORE

  4. 4. Enhanced Methane and Hydrogen production in Reverse Membrane Bioreactors via Syngas Fermentation

    University dissertation from Borås : Högskolan i Borås

    Author : Konstantinos Chandolias; Hariklia N. Gavala; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; syngas fermentation; CH4; H2; cell washout; inhibitors; mass transfer; Resource Recovery; Resursåtervinning;

    Abstract : of waste treatment processes, such as the anaerobic digestion. This biochemical process converts organic substrates into biogas, with anaerobic microorganisms. However, some types of substrates have low bio-degradability due to its recalcitrance or the presence of inhibitors. READ MORE

  5. 5. Synchrotron Radiation, Adsorption Isotherms and the Large Hadron Collider Vacuum System
