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. Organization of information pathways in complex networks

   Author : Atieh Mirshahvalad; Martin Rosvall; Santo Fortunato; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex systems; Complex Networks; Information; Communication; Community Detection; Significance Analysis; Resampling; Information Spreading.; computer and systems sciences; data- och systemvetenskap;

   Abstract : A shuman beings, we are continuously struggling to comprehend the mechanism of dierent natural systems. Many times, we face a complex system where the emergent properties of the system at a global level can not be explained by a simple aggregation of the system's components at the micro-level.

5. 3. Improved Methods for Pharmacometric Model-Based Decision-Making in Clinical Drug Development

   Author : Anne-Gaëlle Dosne; Mats O. Karlsson; Rik Schoemaker; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; nonlinear mixed-effects models; confirmatory trials; residual error modeling; parameter uncertainty; sampling importance resampling; model-averaging; Farmaceutisk vetenskap; Pharmaceutical Science;

   Abstract : Pharmacometric model-based analysis using nonlinear mixed-effects models (NLMEM) has to date mainly been applied to learning activities in drug development. However, such analyses can also serve as the primary analysis in confirmatory studies, which is expected to bring higher power than traditional analysis methods, among other advantages. READ MORE

6. 4. Nonlinear Identification and Control with Solar Energy Applications

   Author : Linda Brus; Bengt Carlsson; Torbjörn Wigren; Graham C. Goodwin; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedforward control; model predictive control; nonlinear control; nonlinear systems; recursive identification; solar power; system identification; time delay systems; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

   Abstract : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. READ MORE

7. 5. Bioinformatic analyses of the structural and functional complexity in chromosomal interactomes

   Author : Alejandro Fernandez Woodbridge; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Evolution requires information storage systems with different demands with respect to persistence. While the genome provides a mechanism for long term, static and accurate information storage, it is incapable of mediating adaptation to short term changes in the environment. READ MORE
