Addressing the Challenges of Situationally-Induced Impairments and Disabilities in Mobile Interaction
Tigwell, Garreth W.; Sarsenbayeva, Zhanna; Gorman, Benjamin M.; Flatla, David R.; Goncalves, Jorge; Yesilada, Yeliz; Wobbrock, Jacob O. (2019-01-01)
Situationally-induced impairments and disabilities (SIIDs) make it difficult for users of interactive computing systems to perform tasks due to context (e.g., listening to a phone call when in a noisy crowd) rather than a ...
Model Predictive Control for a PUC5 based Dual Output Active Rectifier
Makhamreh, Hamza; Trabelsi, Mohamed; Kukrer, Osman; Abu-Rub, Haitham (2019-01-01)
In this paper, an effective finite-control-set model predictive controller (FCS-MPC) is proposed for an active dual output rectifier. The topology under study is a 5-level packed U cells (PUC5) rectifier. The optimized cos...
It's All About the Message! Visual Experience is a Precursor to Accurate Auditory Interaction
Harper, Simon; Eraslan, Sukru; Yesilada, Yeliz (2019-01-01)
Anecdotal evidence suggests there is a disjoint between the interaction experiences of sighted and visually disabled web users. However, we propose the converse and suggest that this disjoint is created by the lack of unde...
Primary Dendrite Trunk Diameter in Al-7wt% Si Alloy Directionally Solidified Aboard the International Space Station
Upadhyay, S. R.; Tewari, S. N.; Ghodes, M.; Grugel, R. N.; Poirier, D. R.; Lauer, M. (2019-01-01)

Combining Trending Scan Paths with Arousal to Model Visual Behaviour on the Web: A Case Study of Neurotypical People vs People with Autism
Matthews, Oludamilare; Eraslan, Sukru; Yaneva, Victoria; Davies, Alan; Yesilada, Yeliz; Vigo, Markel; Harper, Simon (2019-01-01)
People with autism often exhibit different visual behaviours from neurotypical users. To explore how these differences are exhibited on the Web, we model visual behaviour by combining pupillary response, which is an unobtr...
Adults with High-functioning Autism Process Web Pages With Similar Accuracy but Higher Cognitive Effort Compared to Controls
Yaneva, Victoria; Ha, Le An; Eraslan, Sukru; Yesilada, Yeliz (2019-01-01)
To accoiniodate the needs of web users with high-functioning autisi, a designer's only option at present is to rely on guidelines that: i) have not been enpirically evaluated and ii) do not account for the different levels...
Identification of azimuthal light scattering signatures to selectively track changes in subnuclear refractive index profile of epithelial cell models
Arifler, Dizem; Guillaud, Martial (2019-01-01)
We construct stochastically inhomogeneous epithelial cell models via simulation of Gaussian random fields; the extent and correlation length of subnuclear refractive index fluctuations are based on values quantified from h...
A Simple Sliding Mode Controller for PUC7 Grid-Connected Inverter Using A look-up Table
Makhamreh, Hamza; Trabelsi, Mohamed; Kuekrer, Osman; Abu-Rub, Haitham (2019-01-01)
In this paper, a novel and simple controller for seven-level packed U-cell (PUC) grid-connected inverter is presented. The control method is derived based on sliding mode control theory. Making use of the measured grid vol...
Design and Development of a Low Cost Device for Bone Fracture Detection Using FFT Technique on MATLAB
Qadir, Zakria; Ali, Muhammad; Nesimoglu, Tayfun (2018-11-02)
Bone fracture is a common problem in daily life which occurs when high pressure is applied on bone or by simple accident and also due to osteoporosis and bone cancer. Different techniques are used today to detect bone frac...
Smart Solar Micro-grid Using ZigBee and Related Security Challenges
Qadir, Zakria; Tafadzwa, Vincent; Rashid, Haroon; Batunlu, Canras (2018-11-02)
Renewable energy is needed to preserve a sustainable environment. One particular form of renewable energy (solar energy) is one of the most important and cost-effective solutions to the energy crisis. In this study, effici...
Wideband Quarter Wave Transformer Based on Defected Ground and Split Ring Resonator Structures
Yuksek, Yahya; Nesimoglu, Tayfun (2018-11-02)
This article examines a wideband impedance transformer based on a split ring resonator and defected ground structures. The transformer was designed as a 4 section binomial one and it provides a transformation from 50 SI to...
