Using non-speech sounds to increase web image accessibility for screen-reader users
(Chapter; Peer reviewed, 2017)Screen-reader users access images on the Web using alternative text delivered via synthetic speech. However, research shows that this is a tedious and unsatisfying experience for blind users, because text-to-speech ... -
Using Smartphones as Magnifying Devices: A Comparison of Reading Surface Finger Tracking and Device Panning
(PETRA: Pervasive Technologies Related to Assistive Environments; PETRA '20: Proceedings of the 13th ACM International Conference on PErvasive Technologies Related to Assistive Environments, Conference object, 2020-06)Smartphones can be used as magnifying devices to compensate for low visual acuity. However, it can be challenging to pan both vertically and horizontally. To simplify panning we implemented a magnifier where the user moves ... -
Using the Hurst Exponent and Entropy Measures to Predict Effective Transmissibility in Empirical Series of Malaria Incidence
(Applied Sciences;Volume 12 / Issue 1, Peer reviewed; Journal article, 2022-01-05)We analyze the empirical series of malaria incidence, using the concepts of autocorrelation, Hurst exponent and Shannon entropy with the aim of uncovering hidden variables in those series. From the simulations of an agent ... -
Using Tsetlin Machine to discover interpretable rules in natural language processing applications
(Expert systems;, Peer reviewed; Journal article, 2021)Tsetlin Machines (TM) use finite state machines for learning and propositional logic to represent patterns. The resulting pattern recognition approach captures information in the form of conjunctive clauses, thus facilitating ... -
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 ... -
Using virtual reality and rapid prototyping to co-create together with hospitalized children
(Advances in Intelligent Systems and Computing;volume 975, Chapter; Chapter; Peer reviewed, 2020-06-05)This study reports on a social project involving a collaborative process to co-create toys together with hospitalized children, using Virtual Reality, play practices and 3D Printing technologies. The project had two main ... -
Utilization of primary health care services based on countrywide register database in Norway, 10 years after the introduction of the Patient List System
(Journal of Environmental Research and Public Health;11(3), Journal article; Peer reviewed, 2014-03-21)Utilization of services is an important indicator for estimating access to healthcare. In Norway, the General Practitioner Scheme, a patient list system, was established in 2001 to enable a stable doctor-patient relationship. ... -
Validation Methods for Energy Time Series Scenarios From Deep Generative Models
(IEEE Access;Volume: 10, Peer reviewed; Journal article, 2022-01-11)The design and operation of modern energy systems are heavily influenced by time-dependent and uncertain parameters, e.g., renewable electricity generation, load-demand, and electricity prices. These are typically represented ... -
Viewing Browser Content from Extreme Angles with Partial Perspective Corrections
(AVI: Advanced Visual Interfaces;AVI 2022: Proceedings of the 2022 International Conference on Advanced Visual Interfaces, Conference object, 2022-06-06)Displays viewed from extreme angles become perceptually distorted due to perspective projections. Perspective correction has been discussed as a remedy, yet there are few general and practical implementations available to ... -
Viscous Lambda CDM universe models
(Astrophysics and Space Science;333 (2), Journal article; Peer reviewed, 2011-03-30)We explore flat ACDM models with bulk viscosity, and study the role of the bulk viscosity in the evolution of these universe models. The dynamical equations for these models are obtained and solved for some cases of ... -
