1. 1. Long-Term Simulation of Coastal Evolution

   Författare :Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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.

4. 3. In Search of a Fulfilling Identity in a Modern World: Narratives of Indigenous Identities in Sweden and Canada

   Författare :Ebba Olofsson; Hugh Beach; Yngve Lithman; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Cultural anthropology; ethnic identity; personal identity; narratives; Saami; Native; Inuit; Indian; Sweden; Canada; Sápmi; Montreal; Quebec; life cycle; ethnic awakening; Native spritualtity; reindeer herding; political events; Kulturantropologi; Cultural anthropology; Kulturantropologi;

   Sammanfattning : This thesis deals with the identity of individuals with parents from two different ethnic groups. The focus is on individuals in Sweden with one Saami parent and one Swedish (or other European) parent, and individuals in Canada with one Native (Indian or Inuit) parent and one Euro-Canadian parent.

5. 4. A numerical model to simulate short-term beach and dune evolution

   Författare :Jie Zhang; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical model; cross-shore transport; beach profile change; dune erosion; offshore mound; storms;

   Sammanfattning : Sediment transport in the cross-shore (CS) and associated changes in the beach profile, especially during storms, have been topics of widespread concern. Since storms are often accompanied by high water levels and large waves, large quantities of sand from the beach and the dune are typically transported offshore, leading to severe beach and dune erosion, which threatens the integrity of buildings and infrastructure near the coast.

7. 5. Long-term beach and dune evolution : Development and application of the CS-model

   Författare :Caroline Hallin; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coastal processes; sediment transport; numerical modelling; Ängelholm Beach; Kennemer Dunes;

   Sammanfattning : Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. LÄS MER
