  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;

    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. 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

  4. 4. In vitro and in vivo studies on biodegradable matrices for autotransplantation

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

    Author : Carl-Johan Gustafson; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; In vitro; in vivo; dermis; matrix; autotransplantation; culture; keratinocytes; urothelium; tissue engineering; PUUR; macroporous spheres ; guided tissue regeneration;

    Abstract : Tissue engineering (TE), one of the most rapidly growing fields of life science, is an interdisciplinary area in which technical, biological and medical expertise co-fertilize on another with the ultimate aim of restoring, maintaining or improving tissues and/or organs. This purpose links TE closely to research concerning reconstructive plastic surgery. READ MORE

  5. 5. Structure and host-receptor recognition studies of Gram-negative bacterial fimbriae assembled via the chaperone/Usher Pathway

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

    Author : Saumendra Prasad Roy; Sveriges lantbruksuniversitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Enterotoxigenic E. coli (ETEC), enteroaggregative E. coli (EAEC), and Yersinia enterocolitica (YE) are the principle etiological agents of acute and persistent diarrhea worldwide including resource-poor and industrialized regions. READ MORE
