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 performance of differential evolution variants in constrained structural optimization
(Procedia Manufacturing;volume 44, Peer reviewed; Journal article, 2020-05-04)Constrained optimization is a highly important field of engineering as most real-world optimization problems are associated with one or several constraints. Such problems are often challenging to solve due to their complexity ... -
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 ... -
