  2. 11. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints

    Author : Nilsson Olof; Lennart Söder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Integer Constraints; Lagrange relaxation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... READ MORE

  4. 12. Studies of the Arctic Ocean sea ice cover and hydrothermal heat fluxes

    Author : Christian Stranne; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Arctic climate sensisitvity;

    Abstract : Since reliable ice extent estimates from satellite data became available in 1979 the Arctic sea ice cover has followed a declining long term trend. Over the last decade the decline has accelerated with record low sea ice extents recorded in 2002, 2005, 2007 and 2012. READ MORE

  5. 13. Application of Mathematical Programming to Short-Term Operation Planning of Hydrothermal Power System

    Author : Hooshang Habibollahzadeh; Janis Bubenko; Denis Sjelvgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Short-Term Operation Planning; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The thesis contains the results of a reseach project on application of mathematical programming methods to short-term operation planning of large hydrothermal power systems. The project was aimed at devoeloping efficient solution techniques that are practially applicable to large systems. The problem is modeled as a large mixed integer program.. READ MORE

  6. 14. Synthesising Metal Oxide Materials and Their Composite Nanostructures for Sensing and Optoelectronic Device Applications

    Author : Kimleang Khun; Magnus Willander; Omer Nour; Christos Tsamis; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrothermal method; metal oxide nanostructure; composite seed solution; wellaligned ZnO nanorods; composite structures; glucose and dopamine non-enzymatic sensors; heavy metals; supramolecular; UV photodetector sensor;

    Abstract : Research on nanomaterials has been revolutionized in the last few years because of the attractive properties they have in comparison to the bulk phase of similar materials. These properties are physical, chemical, catalytic and optical. READ MORE

  7. 15. A vibrational spectroscopy study of the growth of silicate-1 films on noble metal surfaces

    Author : Vania Engström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : The main objective of this thesis was to acquire a better understanding of the mechanisms involved in the preparation of Silicalite-1 films in general and on gold surfaces in particular. Molecular sieve films on gold surfaces were prepared using the seed film method. READ MORE
