  1. 11. Lokala elektroniska marknadsplatser : informationssystem för platsbundna affärer

    Författare :Johan Petersson; Karin Axelsson; Göran Goldkuhl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Datavetenskap; elektroniska affärer; Internetbaserade tillämpningar; den elektroniska marknadsplatsen; informationssystem; Computer science; Datavetenskap;

    Sammanfattning : Intresset för olika yttringar av elektroniska affärer fokuseras inte sällan på globala och nationella ansträngningar. Detta gäller inte minst sedan uppmärksamheten under senare år kommit att riktas mot Internetbaserade tillämpningar och implikationer av dessa. LÄS MER

  3. 12. Macroeconometric Studies of Private Consumption, Government Debt and Real Exchange Rates

    Författare :Jesper Hansson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; econometrics; Economics; Real exchange rate; Public debt; Structural VAR model; Cointegration; Habits; Permanent income hypothesis PIH ; economic theory; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

    Sammanfattning : Advances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate.

  4. 13. Sustainable Development: Implementation in Urban Water Systems

    Författare :Ali Bagheri; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; pollution control; Environmental technology; Naturvetenskap; Natural science; Water resources systems; Viability loops; Urban water system; System dynamics; Sustainable development; Strategy; Social learning; Process; Principles; Indicators; Planning; Monitoring; kontroll av utsläpp;

    Sammanfattning : As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented the concept from being fully implemented at a practical level. LÄS MER

  5. 14. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation

    Författare :Pradip Aryal; Isabelle Choquet; Muriel Carin; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas metal arc; Electromagnetic force modelling; Free surface deformation; Computational Fluid Dynamics; OpenFOAM; Gasmetallbågsvetsning; Svetsläge; Elektromagnetiskkraftmodellering; Smältytans rörelser; Computational Fluid Dynamics; OpenFOAM; Production Technology; Produktionsteknik;

    Sammanfattning : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. LÄS MER

  7. 15. Development of large-scale molecular and nanomaterial models

    Författare :Mikhail Ivanov; Alexander P. Lyubartsev; Arnold Maliniak; Herre Jelger Risselada; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular simulations; Coarse-grained models; Lipids; TiO2 surface; Machine learning; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Molecular simulations can access unique atomic-scale information about new materials, pharmaceuticals, and biological environments, making cost-effective predictions and aiding experimental studies. They are particularly useful for describing the mechanisms of nanoscale phenomena and the biological/inorganic interfaces. LÄS MER
