1. On Parameter Estimation and Control of Time-Varying Stochastic Systems
Sammanfattning : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.

2. Ny situation - ny organisation : Gatutidningen Situation Sthlm 1995-2000
Sammanfattning : New organizations emerge in times of social change. Their survival depends on their ability to mobilize resources in an environment defined by an old order, and thus they must adapt to it. LÄS MER
3. Iterative and Adaptive PDE Solvers for Shared Memory Architectures
Sammanfattning : Scientific computing is used frequently in an increasing number of disciplines to accelerate scientific discovery. Many such computing problems involve the numerical solution of partial differential equations (PDE). LÄS MER
4. Predation as a driver of reproductive isolation - from adaptive divergence to hybrid inviability
Sammanfattning : Natural selection can play an important role in the origin of new species. When reproductive isolation evolves as a result of ecologically-based divergent natural selection, the process is referred to as ecological speciation. In most organisms, sufficient reproductive isolation is considered to be essential for the establishment of new species. LÄS MER
5. Learning-by-modeling : Novel Computational Approaches for Exploring the Dynamics of Learning and Self-governance in Social-ecological Systems
Sammanfattning : As a consequence of global environmental change, sustainable management and governance of natural resources face critical challenges, such as dealing with non-linear dynamics, increased resource variability, and uncertainty. This thesis seeks to address some of these challenges by using simulation models. LÄS MER
