1. 1. Mathematics textbooks for teaching : An analysis of content knowledge and pedagogical content knowledge concerning algebra in Swedish upper secondary education

   Författare :Wang Wei Sönnerhed; Berner Lindström; Jonas Emanuelsson; Ingemar Holgersson; Göteborgs universitet kommunikation och lärande Institutionen för pedagogik; []
   Nyckelord :mathematics textbooks; school algebra; solving methods; factorization; solving quadratic equations; mathematics teaching; content knowledge; pedagogical content knowledge; geometrical models; algebra history; embedded teaching trajectories;

   Sammanfattning : In school algebra, using different methods including factorization to solve quadratic equations is one common teaching and learning topic at upper secondary school level. This study is about analyzing the algebra content related to solving quadratic equations and the method of factorization as presented in Swedish mathematics textbooks with subject matter content knowledge (CK) and pedagogical content knowledge (PCK) as analytical tools.

3. 2. Fragmentation cross sections: measurement, systematics and model developement

   Författare :Chiara La Tessa; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; projectile total charge-changing cross sections; weak factorization; strong factorization; projectile partial charge-changing cross sections; heavy-ions; space radioprotection; nuclear fragmentation;

   Sammanfattning : Man's attitude towards space exploration has been mainly limited by the health risk related to the exposure to the space radiation environment. Some components of the space field can be characterized by such a high flux to kill a man if directly exposed and in general, all space radiation constitutes a hazard for astronauts engaged in long-term missions.

4. 3. Data-Driven Approaches for Sparse Reflectance Modeling and Acquisition

   Författare :Tanaboon Tongbuasirilai; Jonas Unger; Ehsan Miandji; Jakob Wenzel; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BRDF; Reflectance modeling; Sparse representation; Compressed sensing; Factorization;

   Sammanfattning : Photo-realistic rendering and predictive image synthesis are becoming increasingly important and utilized in many application areas ranging from production of visual effects and product visualization to digital design and the generation of synthetic data for visual machine learning applications. Many essential components of the realistic image synthesis pipelines have been developed tremendously over the last decades. LÄS MER

5. 4. Inverse factorization in electronic structure theory : Analysis and parallelization

   Författare :Anton G. Artemov; Emanuel H. Rubensson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

   Sammanfattning : This licentiate thesis is a part of an effort to run large electronic structure calculations in modern computational environments with distributed memory. The ultimate goal is to model materials consisting of millions of atoms at the level of quantum mechanics. LÄS MER

7. 5. Low Rank Matrix Factorization and Relative Pose Problems in Computer Vision

   Författare :Fangyuan Jiang; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geometric Computer Vision; Low-rank Matrix Factorization; Relative Pose;

   Sammanfattning : This thesis is focused on geometric computer vision problems. The first part of the thesis aims at solving one fundamental problem, namely low-rank matrix factorization. We provide several novel insights into the problem. In brief, we characterize, generate, parametrize and solve the minimal problems associated with low-rank matrix factorization. LÄS MER
