  1. 1. Empowering Empirical Research in Software Design: Construction and Studies on a Large-Scale Corpus of UML Models

    Författare :Truong Ho-Quang; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software Modeling; Software Design; Empirical Research; UML; Modeling Practices; Impacts of Modeling; Open Source System; Mining Software Repository; Data Mining; Data Curation; GitHub;

    Sammanfattning : Context: In modern software development, software modeling is considered to be an essential part of the software architecture and design activities. The Unified Modeling Language (UML) has become the de facto standard for software modeling in industry. LÄS MER

  4. 3. Climate Related Impacts on a Lake : From Physics to Biology

    Författare :Thorsten Blenckner; Rita Adrian; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Ecosystem processes; climate; phytoplankton; NAO; SCI; ice cover; modeling; Biologi; Biology; Biologi; limnologi; Limnology;

    Sammanfattning : Climatic variation and change affect the dynamics of organisms and ecosystem processes. This thesis examines phytoplankton as a target variable to trace climatic impacts on Lake Erken (Sweden) with special emphasis on the spring bloom. LÄS MER

  5. 4. Ghosts and machines : regularized variational methods for interactive simulations of multibodies with dry frictional contacts

    Författare :Claude Lacoursière; Bo Kåggström; Ander Klarbring; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Discrete mechanics; Variational method; Contact problems; Impacts; Least action principle; Saddle point problems; Lagrange Multipliers; Constrained systems; Multibody Systems; Numerical regularization; Constraint realization; Constraint stabilization; Dry friction; Differential Algebraic Equations; Nonsmooth problems; Linear Complementarity; Quaternion algebra; Numerical linear algebra; Physics modeling; Interactive simulation; Numerical stability; Rigid body dynamics; Dissipative systems; Computational physics; Beräkningsfysik;

    Sammanfattning : A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts---machines. LÄS MER

  7. 5. Strategic Life-Cycle Modeling for Sustainable Product Development

    Författare :Henrik Ny; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backcasting; life-cycle assessment LCA ; modeling; planning;

    Sammanfattning : Decision makers are challenged by complex sustainability problems within the socio-ecological system. In response, a vast range of sustainability-related methods/tools have been developed, each focusing on certain aspects of this challenge. LÄS MER
