  1. 21. The wealth of regions : geographic concentration , entrepreneurship and regional growth

    Author : Benny Borgman; Pontus Braunerhjelm; Roger Svensson; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : This thesis consists of three individual essays and an introductory chapter. The essays contribute to the current vein of empirical literature on economic geography and entrepreneurship. READ MORE

  2. 22. Significance of transport dynamics on concentration statistics and expected mass fraction based risk assessment in the subsurface

    Author : Veljko Srzic; Vladimir Cvetkovic; Olaf A. Cirpka; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Local scale dispersion; Heterogeneity structure; Concentration moments; Moment collapse; Expected mass fraction;

    Abstract : This thesis relies on a Langrangian framework used for conservative tracer transport simulations through 2-D heterogeneous porous media. Conducted numerical simulations enable large sets of concentration values in both spatial and temporal domains. READ MORE

  3. 23. Solar Assisted Pervaporation : A process for the concentration of fruit juices in membrane pouches with solar energy

    Author : Randi Phinney; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pervaporation; solar drying; membrane pouch; juice concentration; fruit preservation; marmalade; tangerine; Vangueria infausta; microbiology; water activity; soluble solids; Brix;

    Abstract : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. READ MORE

  4. 24. Spaceborne Synthetic Aperture Radar for Sea Ice Observations, Concentration and Dynamics

    Author : Anders Berg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic aperture radar; interferometry; satellite; sea ice dynamics; sea ice monitoring; sea ice concentration;

    Abstract : Spaceborne Synthetic Aperture Radar (SAR) is the primary choice for sea ice monitoring due to its all-weather, day-and-night capability and regular delivery of high resolution images. This thesis presents methods for estimation of sea ice concentration and drift, a multi-sensor study of Baltic Sea ice radar signatures and an interferometric study of landfast sea ice. READ MORE

  5. 25. Capacitive Mixing for Extracting Concentration Gradient Energy

    Author : Zhi Zou; Longcheng Liu; Chia-Hung Hou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive mixing; salinity gradient energy; salt difference energy; electric double layer; flow electrode CapMix; kapacitiv blandning; salthaltsgradientenergi; saltskillnadsenergi; elektriskt dubbelskikt; flödeselektrod CapMix.; Chemical Engineering; Kemiteknik;

    Abstract : Capacitive mixing (CapMix) is a renewable method of extracting energy from the salinity gradient energy (SGE) between seawater and freshwater. The classical CapMix systems using solid electrodes generate electricity by periodically circulating seawater and freshwater into the CapMix system. READ MORE
