  2. 1. Asymptotics of random matrices and matrix valued processes

    Author : Stefan Israelsson; Kurt Johansson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Random matrices; singular interaction; spectral distribution; fluctuation limit; distribution valued processes; MATEMATIK; MATHEMATICS; MATEMATIK; matematisk statistik; Mathematical Statistics;

    Abstract : This thesis contains three parts. In the first two papers we consider spectral properties of symmetric matrices with elements consisting of independent Ornstein Uhlenbeck processes. The eigenvalues behave as a particle system on the real line with singular interaction consisting of electrostatic repulsion and a linear restoring force. READ MORE

  4. 2. Computational studies of flow in Couette Rheometer and particle interaction in non-Newtonian fluids

    Author : Naser Hamedi; Strömningsteknik; []
    Keywords : Non-Newtonian fluids; Correction factor; Fluid properties; Couette Rheometer; Particle interaction; Sedimentation; Computational Fluid dynamics; Plug flow; Herschel Bulkley; Power-law fluid; Immeresed boundary method;

    Abstract : This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated. READ MORE

  5. 3. Voicing on the borders of language

    Author : Imogen Stidworthy; Konsthögskolan i Malmö; []
    Keywords : HUMANIORA; HUMANITIES; Language; Voicing; Listening; Non-verbal communication; Metacinematic; Rub-up; Installation; Video art; Cinema; Image; Non-retinal image; Sound; Mirroring; Mimesis; Post-cinematic affect; Autism; Aphasia; Cross-modal sensing; Synaesthesia; Psychoanalysis; Neurology; Developmental psychology; Infant development; Intensive interaction; Speech therapy; Auditory surveillance; Forensic listening; Psychiatry;

    Abstract : My research engages with the varieties of relationship between verbal and non-verbal forms of language and communication. I approach the issue through three people who live or work with non-verbal people on the autistic spectrum: Phoebe Caldwell, Fernand Deligny and Iris Johansson. READ MORE

  6. 4. On the fracture behaviour of softwood : a combined experimental and computational study of the interaction between fracture behaviour and material anatomy

    Author : Lars Olof Jernkvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : The propensity for fracture, i.e. failure through separation of the material, is a factor that must be regarded in the design of wooden structures, but also in wood machining operations and drying. READ MORE

  7. 5. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

    Author : Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE
