  1. 1. Towards Asymptotic Vector Quantization

    Författare :Jonas Samuelsson; Chalmers University of Technology; []
    Nyckelord :EM algorithm; parametric models; expectation maximization; spectrum coding; Gaussian mixture models; fast search; bounded support; multidimensional companding; vector quantization; high rate quantization;

    Sammanfattning : 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. LÄS MER

  2. 2. Bacterial DNA repair and molecular search

    Författare :Arvid H. Gynnå; Johan Elf; Stephen Kowalczykowski; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 4. What Does it Take to Get your Attention? : The influence of In-Store and Out-of-Store Factors on Visual Attention and Decision Making for Fast-moving Consumer Goods

    Författare :Poja Shams; Anders Gustafsson; Erik Wästlund; Martin Löfgren; A. Parasuraman; Karlstads universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; point-of-purchase marketing; influencing factors; out-of-store; in-store; shelf space; product packaging; package design; visual attention; visual search; eye-tracking; process-tracing; gaze cascade model; recognition heuristic; familiarity; decision-making; decision-making process; decision-making strategies; heuristic decision-making; preference formation; information processing; Business Administration; Företagsekonomi;

    Sammanfattning : Decision making for fast-moving consumer goods involves a choice between numerous similar alternatives. Under such demanding circumstances, a decision is made for one product. The decision is dependent on the interaction between the environment and the mind of the consumer, both of which are filled with information that can influence the outcome. LÄS MER

  5. 5. Profilin:actin in cell motility : A search for profilin:actin binding proteins

    Författare :Thomas Johansson; Roger Karlsson; Björn Öbrink; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; profilin; actin; Cell biology; Cellbiologi;

    Sammanfattning : The profilin:actin complex is a major source of actin for actin filament growth in vivo. A number of proteins regulating either profilin or actin has been described since profilin:actin was isolated during the 1970s. Since then, profilin and actin and their binding partners have been intensively studied. LÄS MER
