  2. 1. How requirements development could support design of effective and resource-efficient offerings

    Author : Sara Nilsson; Mats Björkman; Erik Sundin; Tomohiko Sakao; Erik Herzog; John Lindström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : What a company offers its customers has to fulfil several different needs, desires, constraints, which can originate from multiple different sources that affect the offering throughout its life cycle. All these criteria have to come together and be translated into statements that can support the designer’s understanding of the offering’s purpose. READ MORE

    Abstract : ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity. Histamine in turn stimulates parietal cells to secrete acid.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; Statistik; operations research; programming; Option pricing; Model validation; Recursive estimation; Diffusion processes; Maximum Likelihood Estimation; operationsanalys; programmering; aktuariematematik; Statistics;

    Abstract : This thesis consists of five papers (Paper A-E) on statistical modeling of diffusion processes. Two papers (Paper A & D) consider Maximum Likelihood estimators for non-linear diffusion processes. READ MORE

  7. 5. A Dynamic View of Melodic Organization and Performance : Perception of Structure and Emotional Expression in Music

    Author : Erik Lindström; Alf Gabrielsson; Andreas C. Lehmann; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; accents; emotion; expression; musical structure; tonal structure; Psykologi; Psychology; Psykologi;

    Abstract : Psychology of music has shown renewed interest in how music expresses emotion to listeners. However, there is an obvious lack of research on how interactions between musical factors such as harmony, rhythm, melodic contour, loudness, and articulation may affect perceived emotion. READ MORE
