  1. 21. Students' narratives from graphical artefacts : Exploring the use of mathematics tools and forms of expression in students' graphicacy

    Author : Oduor Olande; Karl Göran Karlsson; Astrid Pettersson; Luis Radford; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Critical-analytical approach; Graph comprehension; Graphicacy; Graphical artifacts; Statistical literacy; Semiotics; Mathematical Education; Matematikdidaktik;

    Abstract : The research concerns presented in this dissertation addresses aspects of students’ interaction with commonly occurring graphical artefacts in teaching and learning environments. In particular, focus is on how the students make sense of these artefacts in relation to subject specific tools and forms of expression. READ MORE

  2. 22. Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector

    Author : Mats Persson; Mats Danielsson; Hans Bornefalk; Jiang Hsieh; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photon-counting; silicon-strip detector; spectral computed tomography; ring artifacts; fluence rate; basis material decomposition; sub-pixel information; Fysik; Physics;

    Abstract : Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior. READ MORE

  3. 23. Renewing power : Including global asymmetries within the system boundaries of solar photovoltaic technology

    Author : Andreas Roos; Humanekologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; solar energy; photovoltaic technology; ecologically unequal exchange; philosophical materialism; social metabolism; political artifacts; authoritarian technics; machine fetishism; environmental justice; environmental sustainability; solar power;

    Abstract : Solar photovoltaic (PV) technology is one of the most favored means of mitigating climate change. At the same time, there is a growing concern over how this technology is both environmentally harmful and unevenly distributed in the world economy. READ MORE

  4. 24. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Author : Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. READ MORE

  5. 25. Continuous Management of Artifacts and Traceability in Large-Scale Agile Systems Engineering

    Author : Rebekka Wohlrab; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Traceability Management; Large-Scale Agile Development; Empirical Research; Automotive; Systems Engineering; Requirements Engineering;

    Abstract : Context: In large-scale systems engineering, a large number of requirements, models, and other artifacts is created, used, and maintained by many stakeholders. When adopting agile methods and trying to reduce unnecessary documentation, companies need to reevaluate how to manage both artifacts and traceability between them. READ MORE
