  4. 2. Adaptive Finite Element Methods for the Reynolds Thin Film Model with Cavitation

    Author : Bertil Nilsson; Sweden Gothenburg Chalmers University of Technology Department of Applied Mechanics; []
    Keywords : tribology; Reynolds equation; cavitation; FEM; adaptivity; variational inequality; penalty formulation; error estimation; residual; duality;

    Abstract : The main purpose of this thesis is to use modern goal-oriented adaptive finite element techniques in order to improve the numerical simulation of tribology. Two novel adaptive finite element methods for the Reynolds thin film model including cavitation are presented and their different strategies are compared. READ MORE

  5. 3. A robust text processing technique applied to lexical error recovery

    Author : Peter Ingels; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis addresses automatic lexical error recovery and tokenization of corrupt text input. We propose a technique that can automatically correct misspellings, segmentation errors and real-word errors in a unified framework that uses both a model of language production and a model of the typing behavior, and which makes tokenization part of the recovery process.

  6. 4. Studies of safety and critical work situations in nuclear power plants : a human factors perspective

    Author : Lena Kecklund; Erik Hollnagel; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Safety; nuclear power; operators; work-related factors; performance; human error; annual outage; MTO; Psychology; Psykologi; psykologi; Psychology;

    Abstract : The purpose of this thesis was to develop and apply different approaches for analyzing safety in critical work situations in real work settings in nuclear power plants, and also to identify safety enhancing measures by using the framework of interaction between human, organizational and technical subsystems (MTO, man-technology-organization). A Cognitive Psychology as well as a Stress Psychology framework was used. READ MORE

  7. 5. Technology education and non-scientific technological knowledge

    Author : Per Norström; Sven Ove Hansson; Per Sandin; Inga-Britt Skogh; Ibo van de Poel; KTH; []
    Keywords : HUMANIORA; HUMANITIES; rule of thumb; technical knowledge; technological knowledge; technology education; epistemology of technology; design process; modelling;

    Abstract : This thesis consists of two essays and an introduction. The main theme is technological knowledge that is not based on the natural sciences.The first essay is about rules of thumb, which are simple instructions, used to guide actions toward a specific result, without need of advanced knowledge.
