(NIK: Norsk Informatikkonferanse;, Journal article; Peer reviewed, 2012-11-01)Many, although not all people with autistic disorders like Asperger Syndrome, (AS), experience social hindrances and learning difficulties, although they have average or above average intelligence. They interpret the spoken ... -
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 ... -
Entropy and gravity
(Entropy;14, Journal article; Peer reviewed, 2012-12-04)The effect of gravity upon changes of the entropy of a gravity-dominated system is discussed. In a universe dominated by vacuum energy, gravity is repulsive, and there is accelerated expansion. Furthermore, inhomogeneities ... -
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 ... -
Why students plagiarise from the internet: The views and practices in three Norwegian upper secondary classrooms
(International Journal for Educational Integrity;9 (2), Journal article; Peer reviewed, 2013)In a two-part mixed methods study, internet-based plagiarism amongst Norwegian upper secondary students was measured and related to performance level and knowledge of source use. Subsequently, interviews were conducted to ... -
Using Type-2 Fuzzy Models to Detect Fall Incidents and Abnormal Gaits Among Elderly
(Proceedings of System, Man and Cybernetics Conference SMC;2013, Chapter; Peer reviewed, 2013)— June 2012, 11% of the overall population in Taiwan was over the age of 65. This ratio is higher than the average figure for the United Nations (8%) . Critical issues concerning elderly in healthcare include fall ... -
Audition: a DevOps-oriented service optimization and testing framework for cloud environments
(Norsk informatikkonferanse;2013, Journal article; Peer reviewed, 2013)This paper demonstrates an approach to automated testing and quality assurance in cloud environments, which also takes deployment cost into consideration. With a distributed service architecture and some given performance ... -
The Hydra: A layered, redundant configuration management approach for cloud-agnostic disaster recovery
(IEEE International Conference on Cloud Computing Technology and Science;, Chapter; Peer reviewed, 2013)This paper demonstrates a bottom-up approach to developing autonomic fault tolerance and disaster recovery on cloud-based deployments. We avoid lock-in to specific recovery features provided by the cloud itself, and instead ... -
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 ... -
Maximizing hypervisor scalability using minimal virtual machines
(IEEE International Conference on Cloud Computing Technology and Science;, Chapter; Peer reviewed, 2013)The smallest instance offered by Amazon EC2 comes with 615MB memory and a 7.9GB disk image. While small by today's standards, embedded web servers with memory footprints well under 100kB, indicate that there is much to be ... -
A computer supported memory aid for copying prescription parameters into medical equipment based on linguistic phrases
(Proceedings of System, Man and Cybernetics Conference SMC;2013, Chapter; Peer reviewed, 2013)Manually operated medical equipment, including drug infusion pumps, are often subject to input errors.
