2. 1. Coastal Overwash: Processes and Modelling

   Author : Chantal Donnelly; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overwash; washover; hurricane impacts; dune erosion; barrier islands;

   Abstract : Overwash is the flow of water and sediment over the crest of a beach system when the runup level of waves or the water level, often enhanced by storm surge, exceeds the local beach or dune crest height. The impacts of overwash on coastal barriers or low lying mainland coasts are striking. READ MORE

4. 2. Interaction of Hurricanes and Natural Coastal Features: Implications for Storm Damage Reduction

   Author : Ty Wamsley; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Louisiana; Barrier island; Vegetation; Flooding; Waves; Storm surge; Hurricanes; Mathematical modeling; Storm damage reduction;

   Abstract : It is generally acknowledged that wetlands and barrier islands can reduce surge and waves. However, while a general qualitative understanding of these interactions is available in the scientific literature, quantification of these interactions is lacking and has previously been based on limited data of relatively poor quality.

5. 3. The Beach Beneath the Road : Sustainable coastal development beyond governance and economics

   Author : Chad Boda; LUCSUS; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Beach Management; Barrier Island; Flagler; Florida; Sustainability Science; Immanent Critique;

   Abstract : That Florida is in the midst of an ecological crisis is a perspective increasingly shared by academy, government, private industry and civil society. Ideas about the causes of the state’s environmental problems and how best to address them, however, are not so well aligned. READ MORE

6. 4. Thermally stable electrical contacts to 6H silicon carbide

   Author : Nils Lundberg; Mikael Östling; Claude Jaussaud; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; I-V current -voltage ; C-V capacitance-voltage ; rectifying; ohmic; interface; silicide; carbide; epilayer; Schottky barrier height; current rectification ratio CRR ; specific contact resistivity; transmission line model TLM ; contact resistance; transfer length; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform.  Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions.

7. 5. Scanning Tunneling Microscopy Induced Luminescence Studies of Semiconductor Nanostructures

   Author : Ulf Håkanson; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; transmission electron microscopy TEM ; III-V semiconductors; low-dimensional structures; nanostructures; single dot spectroscopy; Stranski-Krastanow; quantum dot QD ; Semiconductory physics; polarization; ordering; InP; GaInP; photon mapping; scanning tunneling microscopy STM ; scanning tunneling luminescence STL ; Halvledarfysik; Fysicumarkivet A:2003:Håkanson;

   Abstract : This thesis treats scanning tunneling luminescence (STL) investigations of semiconductor nanostructures. The STL technique combines scanning tunneling microscopy (STM) with detection of photons, induced by the tunneling electrons. The high spatial resolution in STM and the local excitation allow for optical investigations on the nanometer-scale. READ MORE
