2. 1. Long-Term Simulation of Coastal Evolution

   Author : Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

   Abstract : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. READ MORE

4. 2. Gibbs Measures and Phase Transitions in Potts and Beach Models

   Author : Per Hallberg; KTH; []
   Keywords : Potts model; beach model; percolation; random-cluster model; Gibbs measure; coupling; Markov chains on infinite trees; critical exponent;

   Abstract : The theory of Gibbs measures belongs to the borderlandbetween statistical mechanics and probability theory. In thiscontext, the physical phenomenon of phase transitioncorresponds to the mathematical concept of non-uniqueness for acertain type of probability measures.The most studied model in statistical mechanics is thecelebrated Ising model.

5. 3. Atmosphere-ocean Interactions in Swell Dominated Wave Fields

   Author : Alvaro Semedo; Anna Rutgersson; Oyvind Saetra; Piero Lionello; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Waves; Wind sea; Swell; Swell propagation; MABL; Air-sea interaction; Momentum flux; Wave climate; Coupling; Wave age; Empirical Orthogonal functions; Wave model; Climate model; WAM; RCA; wave heights; Meteorology; Meteorologi; Meteorologi; Meteorology;

   Abstract : Ocean wind waves represent the atmosphere-ocean boundary, playing a central role in the air-sea exchanging processes. Heat, mass and momentum are transferred across this boundary, with waves mediating the exchange of principally the momentum between the winds and the ocean surface. During the generation process waves are called wind sea. READ MORE

6. 4. Multidirectional Mobilities - Advanced Measurement Techniques and Applications

   Author : Lars H. Ivarsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R-DOFs; substructuring; measurement techniques; rotational mobility; multidirectional mechanical mobility; hybrid coupling; coupling; moment mobility; impedance coupling; consistency;

   Abstract : Today high noise-and-vibration comfort has become a quality sign of products in sectors such as the automotive industry, aircraft, components, households and manufacturing. Consequently, already in the design phase of products, tools are required to predict the final vibration and noise levels. READ MORE

7. 5. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer

   Author : Erik Olof Nilsson; Anna Rutgersson; Harm Jonker; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Waves; Growing sea; Swell; Marine boundary layer; Air-sea interaction; Mixing; Momentum flux; Wind stress; Flux attenuation; Sensor separation; Large eddy simulation; Multiresolution analysis; Coupling; Wave model; Climate model; Wave age; Meteorology; Meteorologi;

   Abstract : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. READ MORE
