16. Investigations of problems related to the choice of the initial state for numerical weather prediction models
Sammanfattning : In numerical prediction models, where the wind and mass fields are described as free variables (so called primitive equation models), the initial state has to be carefully chosen, to avoid spurious oscillations in the forecast. This thesis deals with this initialization problem. LÄS MER
17. On the choice of initial state in numerical weather prediction models
Sammanfattning : This thesis deals with the problem of initializing numerical weather prediction models based on the primitive equation system. The normal mode approach is used i.e. the variables are projected on the eigensolutions of the linearized model equations. LÄS MER
18. VLSI Architectures and Arithmetic Operations with Application to the Fermat Number Transform
Sammanfattning : The properties of arithmetic operations in Fermat integer quotient rings 2m+1, where m = 2t, are investigated. The arithmetic operations considered are mainly those involved in the computation of the Fermat number transform. LÄS MER
19. Computational modeling of the lamprey CPG : from subcellular to network level
Sammanfattning : Due to the staggering complexity of the nervous system, computer modelling is becoming one of the standard tools in the neuroscientist's toolkit. In this thesis, I use computer models on different levels of abstraction to compare hypotheses and seek un- derstanding about pattern-generating circuits (central pattern generators, or CPGs) in the lamprey spinal cord.

20. Mathematical modelling approach to collective decision-making
Sammanfattning : In everyday situations individuals make decisions. For example, a tourist usually chooses a crowded or recommended restaurant to have dinner. Perhaps it is an individual decision, but the observed pattern of decision-making is a collective phenomenon. LÄS MER
