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

   Author : Florian Siegmund; Kalyanmoy Deb; Amos H.C. Ng; Sanaz Mostaghim; Högskolan i Skövde; []
   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.

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

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

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

   Author : Björn Zimmer; Andreas Kerren; Hans-Jörg Schulz; Linnéuniversitetet; []
   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

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

   Author : Anastasios Sofiadis; Karolinska Institutet; Karolinska Institutet; []
   Keywords : 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

7. 5. In search of seeds: Exploring and classifying sustainability-oriented labs in real-world contexts

   Author : Gavin McCrory; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; reflexive governance; Sustainability transitions; systematic review; laboratories; learning; transdisciplinarity;

   Abstract : In 2015, the necessity of fundamental change was outlined in the universal, transnational agreement, Agenda 2030, under the headline of “transforming our world”. Underlying transformation, integration, and universality, Agenda 2030 calls for guided ethical and moral action in addition to earnest scientific and technological change. READ MORE
