  2. 16. Towards a flexible statistical modelling by latent factors for evaluation of simulated responses to climate forcings

    Author : Ekaterina Fetisova; Gudrun Brattström; Anders Moberg; Rolf Sundberg; Johan Lindström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Confirmatory Factor Analysis; Measurement Error models; Structural Equation models; Wald confidence interval; Fieller confidence set; Climate model simulations; Climate forcings; Climate proxy data; Detection and Attribution; Mathematical Statistics; matematisk statistik;

    Abstract : In this thesis, using the principles of confirmatory factor analysis (CFA) and the cause-effect concept associated with structural equation modelling (SEM), a new flexible statistical framework for evaluation of climate model simulations against observational data is suggested. The design of the framework also makes it possible to investigate the magnitude of the influence of different forcings on the temperature as well as to investigate a general causal latent structure of temperature data.

  4. 17. Set-up based operator training method in automated manufacturing: A joint production engineering and competence theory approach

    Author : Peter Nordell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production engineering; manufacturing competence; learning;

    Abstract : Productivity improvement strategies such as increased automation, implementation of work cells and introduction of flexible work organisations have changed the content of operator work and the preconditions for training manufacturing competence. Traditional industrial training approaches have become increasingly obsolete. READ MORE

  5. 18. Integrating a Strategic Sustainable Development Perspective in Product-Service System Innovation

    Author : Anthony Thompson; Blekinge Tekniska Högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable product innovation; Sustainable product development; Strategic sustainable development; Product-service systems PSS ; Life cycle management; Set-based product development;

    Abstract : There is an intersection of challenges where society’s social and ecological problems coincide with the industrial firm’s challenge to maintain profitability in a globalizing world. Products connect these challenges. READ MORE

  6. 19. The Dirac Equation: Numerical and Asymptotic Analysis

    Author : Hasan Almanasreh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dirac operator; eigenvalue problem; finite element method; spurious eigenvalues; Petrov-Galerkin; cubic Hermite basis functions; stability parameter; meshfree method; $hp$-cloud; intrinsic enrichment; G-convergence; $ Gamma$-convergence; scattering theory; identification; wave operator; stationary approach; Dirac operator;

    Abstract : The thesis consists of three parts, although each part belongs to a specific subject area in mathematics, they are considered as subfields of the perturbation theory. The main objective of the presented work is the study of the Dirac operator; the first part concerns the treatment of the spurious eigenvalues in the computation of the discrete spectrum. READ MORE

  7. 20. Platform Design for Producibility: Early-Stage Modeling and Assessment Support

    Author : Jonas Landahl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; Mass customization; Platform design; Reuse of design and production information; Enhanced function-means modeling; Set-Based Concurrent Engineering; Producibility assessment; Variety;

    Abstract : In industry, platforms are commonly adopted to reduce unique parts among a variety of distinct product variants, which have proven to be cost-effective within a single platform lifecycle. However, when the platform becomes obsolete or modifications are required to capture changing customer and production needs and requirements, manufacturers often spill tears over the time-consuming and costly processes of reusing and adapting the current platform structure into new.
