    Sammanfattning : In preference-based Evolutionary Multi-objective Optimization (EMO), the decision maker is looking for a diverse, but locally focused non-dominated front in a preferred area of the objective space, as close as possible to the true Pareto-front. Since solutions found outside the area of interest are considered less important or even irrelevant, the optimization can focus its efforts on the preferred area and find the solutions that the decision maker is looking for more quickly, i.

  2. 2. Search Processes, User Behaviour and Archival Representational Systems

    Författare :Anneli Sundqvist; Karen Anderson; Viveca Asproth; Thomas C. Nesmith; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; access; activity theory; information behaviour; records; representation; users; handlingar; användare; informationsbeteende; tillgänglighet; aktivitetsteori; representationer; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Information technology and political motives, e.g. e-governance, freedom of information legislation, has recent years lead to an increasing emphasis on users and access to records, but little research based knowledge about those issues exist so far. The main focus of the previous research is the use of non-current records in archival repositories. LÄS MER

  3. 3. Från guidad visning till shopping och förströdd tillägnelse: moderniserade villkor för ungdomars musikaliska lärande

    Sammanfattning : Abstract In the Swedish compulsory school system there is a trend towards increased student influence. School ideologists have for at least ten years strongly emphasised this issue. This tendency is in line with a more general direction in Western societies, which in many aspects has moved toward individualisation. LÄS MER

  4. 4. Guided Interaction and Collaborative Exploration in Heterogeneous Network Visualizations

    Författare :Björn Zimmer; Andreas Kerren; Hans-Jörg Schulz; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Information Visualization; Multivariate Networks; Visual Analytics; Exploration; Interaction; Collaboration; Provenance; Guidance; Informations- och programvisualisering; Information and software visualization;

    Sammanfattning : The visual exploration of large and complex network structures remains a challenge for many application fields, such as systems biology or social sciences. Often, various domain experts would like to work together to improve the analysis time or the quality of the analysis results. LÄS MER

  5. 5. In search of diagnostic and prognostic markers for thyroid cancer : a proteomics approach

    Författare :Anastasios Sofiadis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Thyroid tumors; thyroid proteomics; S100A6; MIB-1; 2DE; MALDI-TOF-MS; SELDI-TOF-MS; protein pre-fractionation;

    Sammanfattning : Early diagnosis of cancer can influence the therapeutic strategy increasing the chances of cure or, at least, prolonged survival. It is equally important to be able to detect prognostic signs, i.e. tumor features that characterize its behavior. LÄS MER
