16. Deriving landscape metrics from sample data
Sammanfattning : This thesis focuses on the efficiency of using sampling methods to derive landscape metrics. It also explores what sampling methods are to be preferred for different metrics and how metrics in some cases can be redefined to better suit a sample-based data collection framework. LÄS MER
17. Estimating Interviewer Effects in Sample Surveys : Some Contributions
Sammanfattning : This thesis focuses on measurement errors that could be ascribed to the interviewers. To study interviewer variability a measurement error model is formulated which makes a clear distinction between three sources of randomness: the sample selection, interviewer assignment, and interviewing.

19. Drying and thermal modification of wood - studies on influence of sample size, batch size, and climate on wood response
Sammanfattning : Research on wood drying and wood modification is primarily done in laboratories, using clear wood specimens treated under well-defined conditions in laboratory cabinets. Laboratory tests differ from industrial treatment both regarding the size and homogeneity of the material treated, and the size of the batch and kiln used. LÄS MER
20. Investigation on the self-healing capabilties of asphaltic materials using neutron imaging
Sammanfattning : Bitumen acts as a binding agent in asphalt mixtures where it binds the aggregates together. It is known for its potential to heal small cracks and recover its mechanical properties under the right conditions. Though this self-healing property is known, there is currently a lack of knowledge about the mechanisms that drive the process. LÄS MER
