  1. 1. Dynamic Resampling for Preference-based Evolutionary Multi-objective Optimization of Stochastic Systems Improving the efficiency of time-constrained optimization

    University dissertation from Skövde : Högskolan i Skövde

    Author : Florian Siegmund; Högskolan i Skövde.; Högskolan i Skövde.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolutionary multi-objective optimization; simulation-based optimization; guided search; preference-based optimization; reference point; decision support; noise; stochastic systems; dynamic resampling; budget allocation; sequential sampling; hybrid; ranking and selection; Natural sciences; Naturvetenskap; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : 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

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Anneli Sundqvist; Mittuniversitetet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; access; activity theory; information behaviour; records; representation; users; handlingar; användare; informationsbeteende; tillgänglighet; aktivitetsteori; representationer; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Data- och systemvetenskap;

    Abstract : 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. READ MORE

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

    University dissertation from Växjö : Linnaeus University Press

    Author : Björn Zimmer; Linnéuniversitetet.; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. In search of diagnostic and prognostic markers for thyroid cancer : A proteomics approach

    University dissertation from Stockholm : Karolinska Institutet, Department of Molecular Medicine and Surgery

    Author : Anastasios Sofiadis; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thyroid tumors; thyroid proteomics; S100A6; MIB-1; 2DE; MALDI-TOF-MS; SELDI-TOF-MS; protein pre-fractionation;

    Abstract : 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. READ MORE

  5. 5. Targeted Property-Based Testing with Applications in Sensor Networks

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Löscher; Uppsala universitet.; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software Testing; Search-Based Software Testing; Property-Based Testing; Computer Science; Datavetenskap;

    Abstract : Testing is a fundamental part of modern software development, as it unveils bugs in the system under test and gives confidence in their correctness. Testing is often a laborious task as it typically requires to write by hand a plethora of test cases to test a system thoroughly. READ MORE
