  2. 1. Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies

    Author : Eva Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Gaser; fluid dynamics; plasmas; Gases; RSM; CFD; inverse heat transfer; jet impingement heat transfer; infrared heating; termodynamik; Food and drink technology; Livsmedelsteknik; PIV; SST; food; cylinder;

    Abstract : Rapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. READ MORE

  4. 2. Modelling of Jet impingement Heat Transfer for Cooling of Cylindrical Foods

    Author : Eva Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple jets; Nusselt number; cooling; sinle jet; Jet impingement heat transfer; CFD; cylinder; SST; food;

    Abstract : Cooling is an energy consuming operation in the food industry. Rapid cooling reduces the risk of growth of micro-organisms, improves the quality of the food product and increase the production rate... READ MORE

  5. 3. Designing Work Support Systems – For and With Skilled Users

    Author : Eva Olsson; Jan Gulliksen; Carl Åborg; Susan Harker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; human-computer interaction; user involvement; work analysis; work design; user-centred design; Information technology; Informationsteknologi;

    Abstract : Computer users often suffer from poorly designed support systems that hinder them from performing their work efficiently and with satisfaction. The evidence is found in observations of users at work, interviews, evaluations of systems, and numerous reports of systems with poor usability that fail from start. READ MORE

  6. 4. On the impact of extramural English and CLIL on productive vocabulary

    Author : Eva Olsson; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; extramural English; CLIL; writing proficiency; academic vocabulary; second language acquisition;

    Abstract : In this thesis, the possible impact of English encountered and used in two different contexts – in content and language integrated learning (CLIL) and through extramural English (EE) – on students’ writing proficiency is investigated. More specifically, students’ vocabulary use when writing different text types is explored; in particular, attention is drawn to progress in productive academic vocabulary. READ MORE

  7. 5. Media Crisis Decision Making : A Case Study of SR (Swedish Radio), SVT (Swedish Television) and TV4

    Author : Eva-Karin Olsson; Håkan Hvitfelt; Lars Nord; Bengt Johansson; Stockholms universitet; []
