2. 1. Towards Asymptotic Vector Quantization

   Author : Jonas Samuelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EM algorithm; parametric models; expectation maximization; spectrum coding; Gaussian mixture models; fast search; bounded support; multidimensional companding; vector quantization; high rate quantization;

   Abstract : We study topics in source coding, and vector quantization (VQ) in particular. We approach VQ from two directions: a theoretical starting point based on high rate quantization theory, and a practical based on a database desription of the signal source. READ MORE

4. 2. Multi-Agent Mission Planning and Execution for Small Autonomous Underwater Vehicles

5. 3. Bacterial DNA repair and molecular search

   Author : Arvid H. Gynnå; Johan Elf; Stephen Kowalczykowski; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA repair; DNA damage; homologous recombination; homologous repair; recombination; RecA; I-SceI; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

   Abstract : Surveillance and repair of DNA damage is necessary in all kinds of life. Different types of DNA damage require different repair mechanisms, but these mechanisms are often similar in all domains of life. The most serious type of damage, double stranded DNA breaks, are for example repaired in conceptually similar ways in both bacteria and eukaryotes. READ MORE

6. 4. Titanium-Based Negative Electrode Materials for Rechargeable Batteries : In Search of the Redox Reactions

   Author : Tatiana Koriukina; Kristina Edström; Egbert Figgemeier; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; sodium-ion batteries; MXenes; perovskite oxides; redox reactions; XPS; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : Rechargeable batteries, particularly, lithium-ion batteries (LIBs) have proven to be stable and reliable energy storage devices over the past few decades. The rapid demands regarding battery applications and the pressure to move away from the fossil fuel era drive the search for new materials for better rechargeable batteries for electric vehicles, renewable energy storage, and portable electronics.

7. 5. In Search of 'Community' in Zimbabwe's Fast Track Resettlement Area of Mazowe District

   Author : Mabel Hungwe; Institutionen för kulturgeografi och ekonomisk geografi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; COMMUNITY; LAND REFORM; EXIT; LOYALTY; NEGLECT; VOICE; INNOVATION; UNHU; UBUNTU; MAZOWE; ZIMBABWE;

   Abstract : The thesis discusses community development in fast track resettlement areas of Zimbabwe. The land reform programme designated as the Third Revolution (Chimurenga) or fast track land reform was launched in 2000. This programme saw 12 million hectares of farming land being taken over by the state for resettlement. READ MORE
