  1. 11. A moving boundary problem for capturing the penetration of diffusant concentration into rubbers : Modeling, simulation and analysis

    Författare :Surendra Nepal; Adrian Muntean; Yosief Wondmagegne; Magnus Ögren; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moving boundary problem; finite element method; a priori error estimate; a posteriori error estimate; order of convergence; diffusion of chemicals into rubber; swelling; Matematik; Mathematics;

    Sammanfattning : We propose a moving-boundary scenario to model the penetration of diffusants into rubbers. Immobilizing the moving boundary by using the well-known Landau transformation transforms the original governing equations into new equations posed in a fixed domain. LÄS MER

  4. 13. Frege och idén om det givna : En undersökning av logisk form och idén om ett begreppsligt givet innehåll i språket

    Författare :Thorsten Johansson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Philosophy; sense; reference; Sinn; Bedeutung; representations; logical form; intuitions; conceptual content; idealism; realism; a priori; judgements; truth; existence; objectivity; justification; assertion; Filosofi; Philosophy subjects; Filosofiämnen; Theoretical Philosophy; Teoretisk filosofi;

    Sammanfattning : This study is an investigation of some main problems of the philosophy of language initiated by Gottlob Frege. Frege wanted to show that there is a conceptual content in expressions that is not the same as the psychological associations given in intuitions. He also wanted to show that such a content is objective and independent of thesubject. LÄS MER

  5. 14. Interpretation and Alignment of 2D Indoor Maps : Towards a Heterogeneous Map Representation

    Författare :Saeed Gholami Shahbandi; Björn Åstrand; Roland Philippsen; Antanas Verikas; Patric Jensfelt; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Mobile Robots; Autonomous Robots; Robot Perception; Robotic Mapping; Map Interpretation; Semantic Mapping; Place Categorization; Place Labeling; Semantic Annotation; Map Alignment; Region Segmentation; Region Decomposition; Map Representation; Heterogeneous Representation;

    Sammanfattning : Mobile robots are increasingly being used in automation solutions with notable examples in service robots, such as home-care, and warehouses. Autonomy of mobile robots is particularly challenging, since their work space is not deterministic, known a priori, or fully predictable. LÄS MER

  7. 15. Models for capturing the penetration of a diffusant concentration into rubber : Numerical analysis and simulation

    Författare :Surendra Nepal; Adrian Muntean; Nadja Ray; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transport of diffusants; moving-boundary problem; finite element method; a priori and a posteriori error estimates; random walk method; two-scale coupled system; Matematik; Mathematics;

    Sammanfattning : Understanding the transport of diffusants into rubber plays an important role in forecasting the material's durability. In this regard, we study different models, conduct numerical analysis, and present simulation results that predict the evolution of the penetration front of diffusants. LÄS MER
