On second cohomology of duals of compact quantum groups
(International Journal of Mathematics;22 (9), Journal article; Peer reviewed, 2011-09)We show that for any compact connected group G the second cohomology group de ned by unitary invariant 2-cocycles on ^G is canonically isomorphic to H2(\Z(G); T). This implies that the group of autoequivalences of the C ... -
On Shock Propagation through Double-Bend Ducts by Entropy-Generation-Based Artificial Viscosity Method
(Entropy;Volume 21, Issue 9, Journal article; Peer reviewed, 2019-08-22)Shock-wave propagation through obstacles or internal ducts involves complex shock dynamics, shock-wave shear layer interactions and shock-wave boundary layer interactions arising from the associated diffraction phenomenon. ... -
On solving the SPL problem using the concept of probability flux
(Applied intelligence;Volume 49, Issue 7, July 2019, Journal article; Peer reviewed, 2019-02-02)The Stochastic Point Location (SPL) problem [20] is a fundamental learning problem that has recently found a lot of research attention. SPL can be summarized as searching for an unknown point in an interval under faulty ... -
On Taiwanese pupils’ ability to differentiate between English /l/ and /r/: A study of L1/L2 cross-language effects
(First language;Vol 37, Issue 5, Journal article; Peer reviewed, 2017)Students in South East Asia often struggle with English /l/ and /r/. This study therefore set out to examine how Taiwanese pupils’ perception of these sounds is influenced by cross language effects. Most Taiwanese ... -
On the analysis of a random walk-jump chain with tree-based transitions and its applications to faulty dichotomous search
(Sequential Analysis;Volume 37, 2018 - Issue 1, Journal article; Peer reviewed, 2018-03-08)Random Walks (RWs) have been extensively studied for more than a century [1]. These walks have traditionally been on a line, and the generalizations for two and three dimensions, have been by extending the random steps to ... -
On the ballistic perforation resistance of a sandwich structure with aluminium skins and aluminium foam core
(Peer reviewed; Journal article, 2023)Sandwich structures have proven to be excellent energy absorbents and are found in various protective solutions. In this study, an inhomogeneous aluminium foam was used as core material in a sandwich panel with skins of ... -
On the Classification of Dynamical Data Streams Using Novel “Anti–Bayesian” Techniques
(Journal article; Peer reviewed, 2018)The classification of dynamical data streams is among the most complex problems encountered in classification. This is, firstly, because the distribution of the data streams is non-stationary, ... -
On the Convenience of Speeding Up Lecture Recordings: Increased Playback Speed Reduces Learning
(Lecture Notes in Computer Science;Volume 13117, Conference object, 2021-11-23)Audio and video lectures give students much freedom to study where and when they like. These digital media formats usually also give students flexibility to choose the playback speed. In this study we conducted a simple ... -
On the Effects of Omitting Information Exchange between Autonomous Resource Management Agents
(Lecture Notes in Computer Science;7943, Journal article; Peer reviewed, 2013)We study the problem of information exchange between coordinated autonomous resource management agents. We limit information to that which can be directly observed by each agent. While exchanging all relevant observables ... -
On the Energy Performance of Micro-Encapsulated Phase Change Material Enhanced Spackling with Night Ventilation

There are however practical challenges with ensuring adequate ... -
On the existence and characterization of extreme events in wind data
(Conference object, 2019)We present evidence that quantitative definitions of extreme events in wind, so called gusts, may be flawed and unable to grasp true extreme situations of wind velocity in short time intervals. In particular, we show that ... -
On the Global Navigation Satellite Systems and Relativity
(Kart og Plan;73 (1), Journal article; Peer reviewed, 2013)GNSS, or more precisely GNSS-2, is an abbreviation for Glob al Navigation Satellite Systems – Second generation, and serves as a generic name for the class of modern global sa tellite based radio navigation systems. ... -
On the Implications of Sense of Control over Bicycling : Design of a Physical Stamina-Aware Bike
(Proceedings of OZCHI;2010, Chapter; Peer reviewed, 2010)Bicycling has become a mainstream activity among the environmental aware generation. Bicycling communities have gradually shown interests in quantitative data of the bicycling experiences such as road roughness, ... -
On the moments of a polynomial in one variable
(Indagationes Mathematicae;Volume 31, Issue 1, January 2020, Journal article; Peer reviewed, 2019-12-10)Let f be a non-zero polynomial with complex coefficients and define Mn(f) =R1 0 f(x)n dx. We use ideas of Duistermaat and van der Kallen to prove limsupn→∞ |Mn(f)|1/n > 0. In particular, Mn(f) 6= 0 for infinitely many n ∈ N. -
On the non-disabled perceptions of four common mobility devices in Norway: A comparative study based on semantic differentials
(Technology and Disability;Volume 31, Issue 1-2, Journal article; Peer reviewed, 2019)BACKGROUND: Mobility devices such as walkers and wheelchairs are often associated with certain stigma. Such devices must be designed with the goal of reducing stigma to decrease the abandonment-rate. Yet there is little ... -
On the normal sheaf of determinantal varieties
(Journal für die Reine und Angewandte Mathematik;, Journal article; Peer reviewed, 2014-06-18)Let X be a standard determinantal scheme X of P^n of codimension c, i.e. a scheme defined by the maximal minors of a tx(t+c-1)homogeneous polynomial matrix A. In this paper, we study the main features of its normal sheaf ... -
On the Online Classification of Data Streams Using Weak Estimators
(Lecture Notes in Computer Science;9799, Journal article; Peer reviewed, 2016)In this paper, we propose a novel online classifier for complex data streams which are generated from non-stationary stochastic properties. Instead of using a single training model and counters to keep important data ... -
