QB-Gest: Qwerty bimanual gestural input for eye-free smartphone text input
(Lecture Notes in Computer Science;Volume 12188, Conference object, 2020-07-10)We developed QB-Gest, a bimanual text entry method based on simple gestures where users drag their thumbs in the direction of the desired letter while visualizing the Qwerty-layout. In an experiment with four sessions of ... -
Quality of Monitoring Optimization in Underwater Sensor Networks through a Multiagent Diversity-Based Gradient Approach
(Peer reviewed; Journal article, 2023)Due to the complex underwater environment, conventional measurement and sensing methods used for land are difficult to apply directly in the underwater environment. Especially for seabed topography, it is impossible to ... -

Quality teaching and learning as practice within different disciplinary discourses
(International Journal of Teaching and Learning in Higher Education;25 (3), Journal article; Peer reviewed, 2013)This article focuses on describing the interplay between teaching and learning practices in Higher Education and the disciplinary context of such practices. In particular, it aims to address the question of how course ... -
Quantile Estimation Based on the Principles of the Search on the Line
(IFIP Advances in Information and Communication Technology;Vol 519, Chapter; Peer reviewed, 2018-05-22)The goal of our research is to estimate the quantiles of a distribution from a large set of samples that arrive sequentially. We propose a novel quantile estimator that requires a finite memory and is simple to implement. ... -
Quantization of subgroups of the affine group
(Journal of Functional Analysis;Volume 280, Issue 4, 108844, Journal article; Peer reviewed, 2021-02-15)Consider a locally compact group such that V is abelian and the action of Q on the dual abelian group has a free orbit of full measure. We show that such a group G can be quantized in three equivalent ways: (1) by ... -
Quantized Algebras of Functions on Homogeneous Spaces with Poisson Stabilizers
(Journal article; Peer reviewed, 2012-03-01)Let G be a simply connected semisimple compact Lie group with standard Poisson structure, K a closed Poisson-Lie subgroup, 0 < q < 1. We study a quantization C(G q /K q ) of the algebra of continuous functions on G/K. Using ... -
Quantum flag manifolds, quantum symmetric spaces and their associated universal K-matrices
(Advances in Mathematics;Volume 366, 3 June 2020, 107029, Journal article; Peer reviewed, 2020-06-03)Let U be a connected, simply connected compact Lie group with complexification G. Let u and g be the associated Lie algebras. Let Γ be the Dynkin diagram of g with underlying set I, and let Uq(u) be the associated quantized ... -
Quantum Lyapunov exponents beyond continuous measurements
(Chaos;Volume 29, Issue 6, Journal article; Peer reviewed, 2019-10-28)Quantum systems, when interacting with their environments, may exhibit non-equilibrium states that are tempting to be interpreted as quantum analogs of chaotic attractors. However, different from the Hamiltonian case, the ... -
Quantum Riemannian geometry of quantum projective spaces
(Journal of Geometry and Physics;Volume 179, September 2022, 104611, Peer reviewed; Journal article, 2022-07-11)We study the quantum Riemannian geometry of quantum projective spaces of any dimension. In particular, we compute the Riemann and Ricci tensors using previously introduced quantum metrics and quantum Levi-Civita connections. ... -
Quasi-stationary oscillations in game-driven evolutionary dynamics
(Cybernetics and Physics;Volume 8, 2019, Number 4, Journal article; Peer reviewed, 2019-12-24)Nonlinear dynamics makes use of attactors to describe asymptotic behavior of complex systems. However, in real life can be unattainable, as achieving them might require time much exceeding all relevant timescales of a ... -
Quasi-stationary states of game-driven systems: A dynamical approach
(Chaos;Volume 30, issue 12, Journal article; Peer reviewed, 2020-12-28)Evolutionary game theory is a framework to formalize the evolution of collectives (“populations”) of competing agents that are playing a game and, after every round, update their strategies to maximize individual payoffs. ... -
Query-Based Industrial Analytics over Knowledge Graphs with Ontology Reshaping
(Lecture Notes in Computer Science (LNCS);Volume 13384, Peer reviewed; Journal article, 2022-07-20)Industrial analytics that includes among others equipment diagnosis and anomaly detection heavily relies on integration of heterogeneous production data. Knowledge Graphs (KGs) as the data format and ontologies as the ... -
Quick and Easy 3D Modelling for All: A Browser-based 3D-Sketching Framework
(Journal article; Peer reviewed, 2017)Modelling in 3D is considered time-consuming and difficult, relying on special skills. To make matters worse, there are currently no user interface conventions for how to work with 3D data and different modelling applications ... -
Random sparse generators of Markovian evolution and their spectral properties
(Peer reviewed; Journal article, 2023)The evolution of a complex multi-state system is often interpreted as a continuous-time Markovian process. To model the relaxation dynamics of such systems, we introduce an ensemble of random sparse matrices which can be ... -
