1. 1. On Model Simplification in System Identification

   Författare :Bo Wahlberg; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model simplification; System identification;

   Sammanfattning : This report deals with the connection between system identification and model reduction. We propose an identification algorithm that is based on the least squares identification method and either of the model reduction techniques: Frequency weighted truncated balanced realization or frequency weighted optimal Hankel-norm model reduction.

3. 2. Samordning, effektivisering og forenkling : En sosiologisk analyse av begrunnelser for digitaliseringsprosesser i moderniseringen av norsk offentlig forvaltning

   Författare :Jens Petter Madsbu; Mona Lilja; Stefan Karlsson; Hendrik Storstein Spilker; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digitalisation; public electronic communications service; modernisation; public management reform; New Public Management; Digital Era Governance; qualitative research; sociology; Digitalisering; offentlige elektroniske tjenester; modernisering; reformer; offentlig sektor; New Public Management; Digital Era Governance; kvalitativ forskning; sosiologi; Sociologi; Sociology;

   Sammanfattning : This thesis examines the arguments used by politicians and civil servants to justify the implementation of digitalisation processes to modernise and reform the Norwegian public sector. The research questions are “What arguments are used within the Norwegian public administration to justify the implementation of digitalisation processes?” and “How can these arguments be understood in relation to ideas about modernisation and ongoing reforms within the administration more generally?”.

4. 3. Understanding the adaptive capacity of the bumblebee Bombus terrestris across native and novel environments

   Författare :Cecilia Hjort; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bumblebees; Bombus terrestris; Pollination; Introgression; Single nucleotide polymorphisms; Whole Genome Sequencing; Landscape simplification; Gene flow; Morphology; Environmental variation; Invasion; Local adaptation; Island;

   Sammanfattning : Anthropogenic stressors such as agricultural intensification, climate change, andincreased densities of non-native managed bees used for crop pollination arecontributing to bee declines. Understanding how and why bees have responded topast environmental changes is crucial for predicting future ones and enablingmitigation to maintain the functioning of both natural and agricultural ecosystems.

5. 4. Model Reduction for Control of Stirred Tank Reactor Processes

   Författare :Veronica Olesen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QFT; CSTR; sensitivity functions; Model simplification; closed loop;

   Sammanfattning : Models of chemical processes have a tendency of being far too complex for controller design. In many cases these models are also too complex for simulation together with other sub-systems, due to long simulation times and numerical problems. LÄS MER

7. 5. Acquiring L2 Syllable Margins : Studies on the simplification of onsets and codas in interlanguage phonology

   Författare :Niclas Abrahamsson; Björn Hammarberg; Roy Major; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Bilingualism; Tvåspråkighet; tvåspråkighetsforskning; Bilingualism;

   Sammanfattning : This thesis deals with developmental, universal, grammatical, and functional factors involved in the acquisition of L2 syllable structure. More specifically, using speech data from Spanish and Chinese learners of Swedish, the thesis examines the production and development of syllable onsets and codas—that is, syllable margins. LÄS MER
