  1. 1. An Empirical Study of Requirements-Driven Impact Analysis in Object-Oriented Software Evolution

    Författare :Mikael Lindvall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Requirements-driven impact analysis (RDIA) identifies the set of software entities that need to be changed to implement a new requirement in an existing system. RDIA thus involves a transition from requirements to software entities or to a representative model of the implemented system. RDIA is performed during the release planning phase. LÄS MER

  3. 2. A study of traceability in object-oriented systems development

    Författare :Mikael Lindvall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We regard a software system as consisting not only of its source code, but also of its documented models. Traceability is defined as the ability to trace the dependent items within a model and the ability to trace the correspondent items in other models. LÄS MER

  4. 3. A Study on Vanadium Extraction from Fe-V-P Melts Derived from Primary and Secondary Sources

    Författare :Mikael Lindvall; Du Sichen; Christiaan Pistorius; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vanadium; V; V2O5; V2O3; ferrovanadium; vanadiferous; titaniferous; titanomagnetites; magnetite; spinel; slag; experimental; free; spinel; converter; LD; BOF; solubility; equilibrium; selective; oxidation; hibonite; karelianite; Al2O3; CaO; SiO2; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Vanadium extraction methods were developed for iron-vanadium-phosphorus (Fe-V-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. LÄS MER

  5. 4. Adhesive wear testing and modelling of tool steels sliding against sheet metals

    Författare :Fredrik W. Lindvall; Jens Bergström; Pavel Krakhmalev; Mikael Olsson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive wear; Materialteknik; Materials Engineering;

    Sammanfattning : Sheet metal forming is a manufacturing method used because of its versatility. Sheets are plastically deformed by a tool to create a product. A tool is expected to last for several 100,000 forming operations and efforts are made to optimize the tools. A common type of wear referred to as galling is the adhesion of sheet material to the tools. LÄS MER
