  1. 21. Exploring student collaboration during Data Generation in the Statistics Classroom : An Inferentialist Perspective

    Författare :Abdel Seidouvy; Maike Schindler; Ola Helenius; Dani Ben-Zvi; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inferentialism; Collaboration; Data generation; Statistics;

    Sammanfattning : This dissertation explores student collaboration during data generation in statistics. The first aim is to put the semantic theory of inferentialism to work and develop a theoretical lens for exploring student collaboration during data generation. LÄS MER

  3. 22. Representationer, visualisering och resonemang i geometri : Praktiknära studier i digitala lärmiljöer

    Författare :Peter Markkanen; Per Nilsson; Andreas Eckert; Constanta Olteanu; Morten Blomhøj; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geometry; visualization; representations; reasoning; digital tools; design research;

    Sammanfattning : The aim of this dissertation was to gain a deeper understanding of how teaching in digital environments can be designed to give students opportunities to develop knowledge in two- and three-dimensional geometry. The dissertation consists of two sub-studies, the first using an ethnographic approach in which the researcher followed a teacher's teaching in a digital environment, in a Grade 9 class for a period of five weeks.

  4. 23. Image Reconstruction and Optical Flow Estimation on Image Sequences with Differently Exposed Frames

    Författare :Tomas Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple camera settings; human visual system; super-resolution; optical flow; high dynamic range; digital camera system; image reconstruction; motion analysis; inverse problem;

    Sammanfattning : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

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

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

    Sammanfattning : 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. LÄS MER

  7. 25. G-equivariant convolutional neural networks

    Författare :Jimmy Aronsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; deep learning; induced representations; homogeneous vector bundles; convolutional neural networks; homogeneous spaces; symmetry;

    Sammanfattning : Over the past decade, deep learning has revolutionized industry and academic research. Neural networks have been used to solve a multitude of previously unsolved problems and to significantly improve the state-of-the-art on other tasks, in some cases reaching superhuman levels of performance.
