1. 21. Managing the fuzzy front end of product and process development : case studies of process firms

   Författare :Monika Kurkkio; Maria Elmqvist; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Redovisning och styrning; Accounting and Control;

   Sammanfattning : This thesis addresses different aspects of how to manage product development and process development. Two research studies have been conducted, both within the process industry. LÄS MER

3. 22. Tools for Autonomous Process Control

   Författare :Anders Wallén; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential control; software architectures; fast set point response; spectral estimation; frequency domain identification; relay feedback; non-linear system identification; Autonomous Control; Process Control; Grafcet; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor.

4. 23. Learning local predictive accuracy for expert evaluation and forecast combination

   Författare :Oscar Oelrich; Mattias Villani; Francesco Ravazzolo; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian; forecast combination; predictive density; Gaussian process; bootstrap; Bayes factors; model selection; Bayesian predictive synthesis; nonparametric methods; power transformation; expected log predictive density; variable selection; statistik; Statistics;

   Sammanfattning : This thesis consists of four papers that study several topics related to expert evaluation and aggregation. Paper I explores the properties of Bayes factors. Bayes factors, which are used for Bayesian hypothesis testing as well as to aggregate models using Bayesian model averaging, are sometimes observed to behave erratically. LÄS MER

5. 24. Speciation genomics : A perspective from vertebrate systems

   Författare :Nagarjun Vijay; Jochen. B.W Wolf; C. Alex Buerkle; Uppsala universitet; []
   Nyckelord :evolution; speciation; genomics; vertebrate; adaptation; selection; linked selection; crow; killer whale; hybrid zone; transcriptomics; population genetics; behaviour; colouration; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Species are vital entities in biology. Species are generally considered to be discrete entities, consisting of a group of (usually interbreeding) individuals that are similar in phenotype and genetic composition, yet differ in significant ways from other species. LÄS MER

7. 25. On customer value : a study of the IT supplier Atea and three of its customers

   Författare :Sarah Serbin Wikner; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; customer value; selection process; offering content; offering process; customer value assessment; TECHNOLOGY; TEKNIKVETENSKAP; Business studies;

   Sammanfattning : At the turn of the twenty-first century, the PC company Dell was known for its "famous direct method" (Afuah and Tucci, 2003), which alludes to the direct business model. Dell created a tightly aligned business model that enabled it to manage away the need for its component inventories (Jonathan Bymes, 2003). LÄS MER
