1. 1. Winter browsing by moose and hares in subarctic birch forest : Scale dependency and responses to food addition

   Författare :Sara Öhmark; Thomas Palo; Glenn R. Iason; Bengt-Gunnar Jonsson; Lisa Shipley; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Herbivory; subarctic; hare; moose; spatial scale;

   Sammanfattning : Despite their difference in body size and morphology, the moose (Alces alces) andthe mountain hare (Lepus timidus) sustain themselves during winter on similar plantspecies and plant parts in in subarctic environments, namely apical twigs ofmountain birch (Betula pubescens ssp. czerepanovii).

3. 2. The effect of scale on the morphology, mechanics and transmissivity of single rock fractures

   Författare :Nader Fardin; KTH; []
   Nyckelord :Anisotropy; Aperture; Asperity degradation; Contact area; Finite Element Method FEM ; Flow analysis; Fractals; Fracture morphology; Heterogeneity; Stress-deformation; Surface roughness; Roughness-Length method; Scale dependency; Stationarity; Transm;

   Sammanfattning : This thesis investigates the effect of scale on themorphology, mechanics and transmissivity of single rockfractures using both laboratory and in-situ experiments, aswell as numerical simulations. Using a laboratory 3D laserscanner, the surface topography of a large silicon-rubberfracture replica of size 1m x 1m, as well as the topography ofboth surfaces of several high-strength concrete fracturereplicas varying in size from 50mmx50mm to 200mm x 200mm, werescanned.

4. 3. Efficient Full-Scale CFD for Ship Hydrodynamics

   Författare :Michal Orych; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; CFD; Self-propulsion; Ship; Verification; Uncertainty; Full-scale; Validation; Seakeeping; Energy-Saving Device; Roughness; RANS;

   Sammanfattning : An efficient numerical approach for ship hydrodynamics, involving a hybrid free-surface potential flow/RANS method, is explored. The work focuses on estimating the delivered power of ships in calm water and in waves, highlighting the benefits of full-scale simulations, particularly for ships with Energy Saving Devices.

5. 4. Transition-Based Natural Language Parsing with Dependency and Constituency Representations

   Författare :Johan Hall; Joakim Nivre; Welf Löwe; Sandra Kübler; Växjö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural Language Parsing; Syntactic Parsing; Dependency Structure; Phrase Structure; Machine Learning; Computer science; Datavetenskap; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

   Sammanfattning : Denna doktorsavhandling undersöker olika aspekter av automatisk syntaktisk analys av texter på naturligt språk. En parser eller syntaktisk analysator, som vi definierar den i denna avhandling, har till uppgift att skapa en syntaktisk analys för varje mening i en text på naturligt språk. LÄS MER

7. 5. Cognition and activity early after stroke

   Författare :Tamar Abzhandadze; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute stroke; Activities of Daily Living; Cognition; Function; Functional cognition; Dependency; Global disability; Prediction; Screening; Assessment; Stroke unit; Registries; Ischemic stroke; Intracerebral hemorrhage; Occupational therapy; Rehabilitation;

   Sammanfattning : Introduction and aims: Cognitive impairment and dependency in activities of daily living (ADL) are common consequences of stroke. Due to a decrease in the length of hospital stay, assessment of these conditions has become necessary for the planning of discharge and rehabilitation. LÄS MER
