Sense and reference of signifiers for elements of polygons
(Chapter, 2019)This paper is based mainly on a planning meeting involving teachers and researchers before classroom sessions in a Norwegian school where 7-8-year-old children are working with concepts connected to geometrical shapes. ... -
Shape analysis on homogeneous spaces: a generalised SRVT framework
(Chapter, 2017)Shape analysis is ubiquitous in problems of pattern and object recognition and has developed considerably in the last decade. The use of shapes is natural in applications where one wants to compare curves independently of ... -
Shortcomings in the milieu for algebraic generalisation arising from task design and vagueness in mathematical discourse
(Chapter, 2013)This paper presents how the milieu for students’ engagement with an algebraic generalisation task is constrained by two factors: first, by the task design; second, by the students’ unawareness of the nature of a mathematical ... -
Shorter QA-NIZK and SPS with Tighter Security
(Chapter, 2019)Quasi-adaptive non-interactive zero-knowledge proof (QA-NIZK) systems and structure-preserving signature (SPS) schemes are two powerful tools for constructing practical pairing-based cryptographic schemes. Their efficiency ... -
Side channels in deduplication: trade-offs between leakage and efficiency
(Chapter, 2017)Deduplication removes redundant copies of files or data blocks stored on the cloud. Clientside deduplication, where the client only uploads the file upon the request of the server, provides major storage and bandwidth ... -
Symmetries and multipeakon solutions for the modified two-component Camassa-Holm system
(Chapter, 2018)Compared with the two-component Camassa–Holm system, the modified two-component Camassa–Holm system introduces a regularized density which makes possible the existence of solutions of lower regularity, and in particular ... -
Teaching the concept of angles to multilingual learners

Topic Study Group No. 11: Teaching and Learning of Algebra
(Chapter; Peer reviewed, 2017)TSG-11 on Teaching and Learning of Algebra had a small number of presentations in the main session, leaving enough space for discussions and dialogue. The TSG planned to cover the salient themes and ideas in algebra ... -
Universal Zero Dynamics: The SISO Case
(Chapter, 2021)Given a single-input, single-output (SISO) system with a Chen-Fliess series representation whose generating series has a well defined relative degree, it is shown that there is a notion of universal zero dynamics that ... -
Use of dynamically adapted basis functions to accelerate multiscale simulation of complex geomodels
(Chapter, 2018)A number of different multiscale methods have been developed as a robust alternative to upscaling and as a means for accelerated reservoir simulation of high-resolution geomodels. In their basic setup, multiscale methods ... -
Workshop on classroom research: Analysis of transcript data
(Chapter, 2007)This paper is a report of the workshop initiated by the Nordic Graduate School inMathematics Education. The paper focuses especially on the decisions taken in the planning of the workshop and how the plans were implemented. ... -
Zeroing the Output of Nonlinear Systems Without Relative Degree
(Chapter, 2023)The goal of this paper is to establish some facts concerning the problem of zeroing the output of an input-output system that does not have relative degree. The approach taken is to work with systems that have Chen-Fliess ...
