1. Element 115
Sammanfattning : This thesis is devoted to detailed studies of element 115 decay chains using the highly efficient multi-coincidence alpha, electron, gamma and X-ray detector setup TASISpec at the gas-filled separator TASCA at GSI, Darmstadt, Germany. In a three-week long experiment thirty new decay chains assumed to stem from element 115 isotopes were observed together with the very first detections of gamma rays and potential X-rays from these nuclei.

2. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling
Sammanfattning : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. LÄS MER
3. Corotational formulation for nonlinear analysis of flexible beam structures
Sammanfattning : Flexible beam structures are popular in civil and mechanical engineering. Many of these structures undergo large displacements and finite rotations, but with small deformations. Their dynamic behaviors are usually investigated using finite beam elements. A well known method to derive such beam elements is the corotational approach. LÄS MER
4. Reference setup for characterization and calibration of low-range differential pressure sensors
Sammanfattning : In this thesis, a reference setup for the characterization and calibration of low range differential pressure sensors is presented. The setup utilizes the principle of ideal gas law and actuates on the volume for accurate reference pressure inputs for the calibration process. LÄS MER
5. Mot en ny vuxenutbildningspolitik? : Regional utveckling som policy och praktik
Sammanfattning : Avhandlingen beskriver och analyserar ett regionalt utvecklingsinitiativ i nätverksform, genom vilket de kommunala lärcentrumen i Örebro län samverkar för att utveckla en gemensam infrastruktur för vuxnas lärande. Detta innebär, exempelvis, att utveckla former för samverkan mellan olika regionala aktörer inom området, öka samordningen och samverkan inom den kommunala vuxenutbildningen och utveckla metoder för lärande med fokus på arbetet och arbetsplatsen.
