2. 1. Modelling and Management of Uncertainty in Production Systems : from Measurement to Decision

   Author : Károly Szipka; Andreas Archenti; Sten Dr. Bergstrand; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precision engineering; Uncertainty modelling; Machin-ing system capability; Production Engineering; Industriell produktion;

   Abstract : The advanced handling of uncertainties arising from a wide range of sources is fundamental in quality control and dependability to reach advantageous decisions in different organizational levels of industry. Es-pecially in the competitive edge of production, uncertainty shall not be solely object of estimation but the result of a systematic management process. READ MORE

4. 2. Mathematical modelling approach to collective decision-making

   Author : Natalia Zabzina; Denis Gaidashev; Torbjörn Lundh; Uppsala universitet; []
   Keywords : collective behaviour; collective decision-making; communication mechanisms; positive feedback; mathematical modelling; bifurcation phenomena; steady state solutions; symmetry breaking; symmetry restoring; diffusion-limited aggregation; fractal dimension;

   Abstract : In everyday situations individuals make decisions. For example, a tourist usually chooses a crowded or recommended restaurant to have dinner. Perhaps it is an individual decision, but the observed pattern of decision-making is a collective phenomenon. READ MORE

5. 3. Towards a learning system for process and energy industry : Enabling optimal control, diagnostics and decision support

   Author : Moksadur Rahman; Konstantinos Kyprianidis; Anders Avelin; Bengtsson Gunnar; Agostino Gambarotta; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning system; Supervisory system; Pulp and paper; Micro gas turbine; Process modelling; Model-based control; Diagnostics; Decision support; Anomaly detection; Fault detection; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Driven by intense competition, increasing operational cost and strict environmental regulations, the modern process and energy industry needs to find the best possible way to adapt to maintain profitability. Optimization of control and operation of the industrial systems is essential to satisfy the contradicting objectives of improving product quality and process efficiency while reducing production cost and plant downtime.

6. 4. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making

   Author : Ruoqi Wang; John Leander; Raid Karoumi; Boulent Imam; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; steel bridges; decision-making; reliability analysis; risk analysis; spatial correlation; system modelling; inspection and maintenance; Utmattning; stålbroar; beslutsfattande; tillförlitlighet; riskanalys; rumslig korrelation; systemmodellering; inspektion och underhåll; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Abstract : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. READ MORE

7. 5. Modelling Phone-Level Pronunciation in Discourse Context

   Author : Per-Anders Jande; Rolf Carlson; Merle Horne; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pronunciation modelling; Pronunciation variation; Discourse-context; Phone-level variation; Central standard Swedish; Spoken language annotation; Data-driven methods; Machine learning; Decision trees; Pronunciation lexicon development; Machine-readable lexicon; Phonology; Discourse; Lexicon; Language technology; Språkteknologi;

   Abstract : Analytic knowledge about the systematic variation in a language has an important place in the description of the language. Such knowledge is interesting e.g. in the language teaching domain, as a background for various types of linguistic studies, and in the development of more dynamic speech technology applications.
