1. 6. 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. 7. Graphical representations of Ising and Potts models : Stochastic geometry of the quantum Ising model and the space-time Potts model

   Författare :Jakob Erik Björnberg; Anders Björner; Jeffrey Steif; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Ising model; Ising model; Potts model; random-cluster model; random-current representation; random-parity representation; differential inequality; phase transition; Discrete mathematics; Diskret matematik;

   Sammanfattning : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. LÄS MER

4. 8. Design of Business Process Model Repositories : Requirements, Semantic Annotation Model and Relationship Meta-model

   Författare :Mturi Elias; Ilia Bider; Paul Johannesson; Marlon Dumas; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; business process; business process model; business process repository; semantic annotation; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : Business process management is fast becoming one of the most important approaches for designing contemporary organizations and information systems. A critical component of business process management is business process modelling. LÄS MER

5. 9. Model Selection and Sparse Modeling

   Författare :Yngve Selén; Peter Stoica; Jean-Jacques Fuchs; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model selection; model order selection; model averaging; nested models; sparse models; Bayesian inference; MMSE estimation; MAP estimation; ML estimation; AIC; BIC; GIC; RAKE receivers; pulse compression; radar; linear models; linear regression models; Signal processing; Signalbehandling;

   Sammanfattning : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. LÄS MER

7. 10. Model-based coding : extraction, coding, and evaluation of face model parameters

   Författare :Jörgen Ahlberg; Andrew Senior; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis deals with model-based coding of human faces for low bitrate communication. The basicidea of model-based coding is that the appearance and motion of a human face are analysed. By thisanalysis, compact parameters allowing realistic visualization of a synthetic face are extracted. LÄS MER
