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 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 ... -
On the Performance of Bidirectional NOMA-SWIPT Enabled IoT Relay Networks
(IEEE Sensors Journal;Volume: 21, Issue 2, Journal article; Peer reviewed, 2020-08-24)In this article, a bidirectional relaying (BR) non-orthogonal multiple access (NOMA) with simultaneous wireless information and power transfer (SWIPT) termed as BR NOMA-SWIPT is proposed and investigated for the Internet ... -
On the relativity of rotation
(Nuovo cimento. B;(7), Journal article; Peer reviewed, 2010)The question whether rotational motion is relative according to the general theory of relativity is discussed. Einstein’s ambivalence concerning this question is pointed out. In the present article I defend Einstein’s way ... -
On the statistical nature of distinct cycles in global warming variables
(Peer reviewed; Journal article; Journal article, 2017-01-10)Cycle times found in many oceanic time series have been explained with references to external mechanisms that act on the systems. Here we show that when we extract cycle times from 100 sets of paired random series, we find ... -
On the Truthfulness of Petal Graphs for Visualisation of Data
(NIK: Norsk Informatikkonferanse;, Journal article; Peer reviewed, 2012-11-01)A petal graph is an aesthetically attractive and applauded tool for visualising parameter sets. For instance, petal graphs are often used by Norwegian policy makers and decision makers in higher education as the Ministry ... -
On the Understandability of Public Domain Icons: Effects of Gender and Age
(Lecture Notes in Computer Science;9175, Journal article; Peer reviewed, 2015-07-18)Icons and symbols are often deployed in graphical user interfaces. It is commonly believed that icons add to the user friendliness of products. Devel‐ opers have great trust in icon libraries and they are likely to use ... -
On the usefulness of Aaa-links for controlling text size on web pages : preliminary results
(The proceedings of Unitech2010 : International Conference on Universal Technologies;, Chapter; Peer reviewed, 2010)Aaa-links, also known as triple-a links, have over the last few years become commonplace on the web. In a move to become more universally accessible organizations have introduced Aaa-links to help users with reduced ... -
On the usefulness of off-the-shelf computer peripherals for people with Parkinson’s Disease
(Journal article; Peer reviewed, 2011-10-05)People who suffer from Parkinson’s Disease face many challenges using computers, and mice are particularly problematic input devices. This article describes usability tests of standard peripherals for use by people ... -
On Time Reading Performance: A Comparison of the Clock Face and Digit Representations
(Lecture Notes in Computer Science;, Chapter; Peer reviewed; Conference object; Journal article, 2023)Time plays an essential part of our lives. We are typically surrounded by two types of time representation, clock faces and digits. Previous work focused on children’s ability to read time, but adults’ ability to read time ... -
On Using Novel "Anti-Bayesian" Techniques for the Classification of Dynamical Data Streams
(Chapter; Peer reviewed, 2017)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, and it changes without any ... -
On utilizing weak estimators to achieve the online classification of data streams
(Engineering Applications of Artificial Intelligence;Volume 86, November 2019, Journal article; Peer reviewed, 2019-09-02)Classification, typically, deals with unique and distinct training and testing phases. This paper pioneers the concept when these phases are not so clearly well-defined. More specifically, we consider the case where the ... -
