Special Issue on Cloud Computing, IoT, and Big Data: Technologies and Applications (CloudTech17), e5662, Journal article; Peer reviewed, 2020-02-05)Hybrid cloud technology is becoming increasingly popular as it merges private and public clouds to bring the best of two worlds together. However, due to the heterogeneous cloud installation, facilitating a hybrid cloud ... -
On Converting Crisp Failure Possibility into Probability for Reliability of Complex Systems
(Lecture Notes in Networks and Systems;Volume 308, Peer reviewed; Journal article, 2021-08-24)The reliability of complex systems is analyzed based on several systematic steps using many safety engineering methods. The most common technique for safety system analysis and reliability, vulnerability and criticality ... -
On Cooperation Versus Competition Between Autonomous Resource Management Agents
(Norsk informatikkonferanse (NIK);2013, Journal article; Peer reviewed, 2014-03-13)A common issue in distributed systems is how to optimize resource sharing when several resource management agents have access to the same resource pool. When the total resource demand reaches max capacity of the common ... -
On deformations of C*-algebras by actions of Kahlerian Lie groups
(Journal article; Peer reviewed, 2016)We show that two approaches to equivariant strict deformation quantization of C∗-algebras by actions of negatively curved Kählerian Lie groups, one based on oscillatory integrals and the other on quantizations maps defined ... -
On Distinguishing between Reliable and Unreliable Sensors Without a Knowledge of the Ground Truth
(Peer reviewed; Chapter, 2015)In many applications, data from different sensors are aggregated in order to obtain more reliable information about the process that the sensors are monitoring. However, the quality of the aggregated ... -
On English Speakers Ability to Communicate Emotion in Mandarin
(Journal article; Peer reviewed, 2014)The ability of Mandarin learners to express emotion in Mandarin has received little attention. This study examines how English L1 users express emotions in Mandarin and how this expression differs from that of Mandarin ... -
On evaluation metrics for medical applications of artificial intelligence
(Scientific Reports;12, Article number: 5979 (2022), Peer reviewed; Journal article, 2022-04-08)Clinicians and software developers need to understand how proposed machine learning (ML) models could improve patient care. No single metric captures all the desirable properties of a model, which is why several metrics ... -
On Neural Associative Memory Structures: Storage and Retrieval of Sequences in a Chain of Tournaments
(Neural Computation;Volume 33, Issue 9, Peer reviewed; Journal article, 2021-08-19)Associative memories enjoy many interesting properties in terms of error correction capabilities, robustness to noise, storage capacity and retrieval performance and their usage spans over a large set of applications. In ... -
On Online Banking Authentication for All: A Comparison of BankID Login Efficiency Using Smartphones Versus Code Generators
(Lecture Notes in Artificial Intelligence;volume 11572, Journal article; Peer reviewed, 2019)Authentication is an essential component of any digital service. In Norway, such authentication is often relying on BankID using either mobile BankID or a code generator. This study set out to explore the efficiency of ... -
On optimizing firewall performance in dynamic networks by invoking a novel swapping window-based paradigm
(International Journal of Communication Systems;Volume 31, Issue 15 October 2018, Journal article; Peer reviewed, 2018-07-24)Designing and implementing efficient firewall strategies in the age of the Internet of Things (IoT) is far from trivial. This is because, as time proceeds, an increasing number of devices will be connected, accessed and ... -
On PBW-Deformations of Braided Exterior Algebras
(Advances in Applied Clifford Algebras;29:8, Journal article; Journal article; Peer reviewed, 2018-11-26)We classify PBW-deformations of quadratic-constant type of certain quantizations of exterior algebras. These correspond to the fundamental modules of quantum slN, their duals, and their direct sums. We show that the first ... -
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 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 ... -
