1. 1. Managing a cross-institutional setting : a case study of a Western firm's subsidiary in the Ukraine

   Författare :Peter Hultén; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Boundary Spanning; Consonance; Cross-Institutional; Dissonance; Filtering; Filtering Conditions; Identity Identification; Institutional Influence; Networks; Norms; Post-Soviet Market; Power; Screening; Socialisation; Vacuum; Företagsetablering; Ukraina; Nätverksplanering; Multinationella företag; Dotterbolag; Postkommunism;

   Sammanfattning : This study explores the development of a Western firm's subsidiary in the Ukraine and sets out to contribute to the theoretical development about the managing of subsidiaries in the Post-Soviet market. The cross-institutional approach to analyse the subsidiary has been adopted to explore influence from the institutional setting of the parent firm and from local institutions. LÄS MER

3. 2. Continuous-filtering Vernier spectroscopy

   Författare :Chuang Lu; Aleksandra Foltynowicz; Ove Axner; Wei Ren; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; spectrometer; laser; optical frequency comb; optical cavity; NIR; MIR; flame; robust; time resolution; spectrum; fysik; Physics;

   Sammanfattning : Continuous-filtering Vernier spectroscopy (CF-VS) is a laser-based detection technique that combines the broad spectral coverage of an optical frequency comb (OFC) with the enhanced interaction length provided by an optical cavity. The resonances of the cavity filter the OFC to a small group of comb modes that probe the transitions of the species present in the cavity. LÄS MER

4. 3. Environmental filtering of bacteria in low productivity habitats

   Författare :Inga Richert; Stefan Bertilsson; Annelie Wendeberg; Lise Øvreås; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteria; environmental filtering; diversity; ecosystem service; hydrocarbon utilization; Southern Ocean; sediment; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

   Sammanfattning : Microbes fulfill important ecosystem functions by contributing as drivers of global nutrient cycles. Their distribution patterns are mainly controlled by environmental heterogeneities. So far, little is known about the mode of action of particular environmental drivers on the microbiota, particularly in low productivity habitats. LÄS MER

5. 4. Data Filtering and Control Design for Mobile Robots

   Författare :Maja Karasalo; Xiaoming Hu; John Baras; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; formation control; tracking; nonlinear control; optimal smoothing; adaptive filtering; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : In this thesis, we consider problems connected to navigation and tracking for autonomousrobots under the assumption of constraints on sensors and kinematics. We study formation controlas well as techniques for filtering and smoothing of noise contaminated input. The scientific contributions of the thesis comprise five papers. LÄS MER

7. 5. WAVELET NOISE REDUCTION AND VASCULAR WATER TRANSPORT MODELLING : APPLICATIONS TO DIFFUSION AND PERFUSION MRI

   Författare :Adnan Bibic; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral blood flow; perfusion; diffusion; arterial spin labelling; wavelets; filtering; denoising; blood-brain barrier; permeability; Fysicumarkivet A:2018:Bibic;

   Sammanfattning : Magnetic resonance imaging (MRI) is a powerful medical imaging technique, used to detect and characterise a range of diseases and conditions. It is based on the use of a strong static magnetic field in combination with magnetic field gradients and pulsed radiofrequency electromagnetic fields to visualise various organs and structures in the body according to their morphology or function.
