21. Design-based sampling methods for environmental monitoring
Sammanfattning : Efficient strategies for environmental monitoring are proposed with an emphasis on the importance of using available information. In environmental monitoring, it is common to use area frames covering the assumed spread of the population of inter-est. LÄS MER
22. Improved Methods for Pharmacometric Model-Based Decision-Making in Clinical Drug Development
Sammanfattning : Pharmacometric model-based analysis using nonlinear mixed-effects models (NLMEM) has to date mainly been applied to learning activities in drug development. However, such analyses can also serve as the primary analysis in confirmatory studies, which is expected to bring higher power than traditional analysis methods, among other advantages. LÄS MER
23. Bayesian Inference for Nonlinear Dynamical Systems : Applications and Software Implementation
Sammanfattning : The topic of this thesis is estimation of nonlinear dynamical systems, focusing on the use of methods such as particle filtering and smoothing. There are three areas of contributions: software implementation, applications of nonlinear estimation and some theoretical extensions to existing algorithms. LÄS MER
24. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion rates
Sammanfattning : The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. LÄS MER
25. Semipermeable membrane devices as integrative tools for monitoring nonpolar aromatic compounds in air
Sammanfattning : Air pollutants pose a high risk for humans, and the environment, and this pollution is one of the major environmental problems facing modern society. Active air sampling is the technique that has been traditionally used to monitor nonpolar aromatic air pollutants. LÄS MER
