Visual determinants of postural control and perception during physical and visual motion
(University of Waterloo, 2023-01-30)The control of balance and posture is a critical task of daily life to limit the risk of falls and potential injury. In order to be successful in the control of balance the central nervous system utilizes sensory feedback ... -
Visual Functions in Parkinson’s Disease
(University of Waterloo, 2018-06-19)Background: Freezing of gait (FOG) is considered to be a motor disorder symptom that affects some Parkinson Disease (PD) patients; however, it is hypothesized that sensory systems may also be involved in FOG. Purpose: ... -
Visual Functions in Post-Concussion Syndrome
(University of Waterloo, 2018-10-24)Purpose: Post-concussion syndrome (PCS) is a is a complex neurological disorder in which various concussion symptoms can last for weeks, months, or even years after sustaining the concussion. The PCS population has been ... -
Visual Impairment in the City: Young People's Social Strategies for Independent Mobility
(Sage, 2013-02-01)This article examines the mobility strategies that visually impaired (VI) young people employ as they negotiate their daily lives in the city. In contrast to research which foregrounds difficulties navigating the built ... -
Visual Inputs and Motor Outputs as Indivduals Walk Through Dynamically Changing Environments
(University of Waterloo, 2006-12-01)Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides ... -
VISUAL INPUTS AND MOTOR OUTPUTS AS INDIVIDUALS WALK THROUGH DYNAMICALLY CHANGING ENVIRONMENTS
(University of Waterloo, 2006)Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides ... -
Visual optical biosensors based on DNA-functionalized polyacrylamide hydrogels
(Elsevier, 2013-12-15)Biosensors are devices that can provide quantitative or semi-quantitative analytical information about target molecules, where molecular recognition is based on biomolecular interactions. In recent years, DNA has emerged ... -
Visual Sensitivity of Dynamic Graphical Displays
(University of Waterloo, 2005)Advanced display design, such as Ecological Interface Design (EID), makes extensive use of complex graphical objects. Research has shown that by following EID methodologies, supervisory operators have better performance ... -
Visual Word Recognition: Evidence for Global and Local Control over Semantic Feedback
(University of Waterloo, 2007-09-26)Two semantic priming experiments in the context of lexical decision are reported that examine the joint effects of stimulus quality, semantic context, and strength of association when all these factors are intermixed in a ... -
Visual-Inertial Odometry for 3D Pose Estimation and Scene Reconstruction using Unmanned Aerial Vehicles
(University of Waterloo, 2019-12-20)As Unmanned Aerial Vehicles (UAVs) become increasingly available, pose estimation remains critical for navigation. Pose estimation is also useful for scene reconstruction in certain surveillance applications, such as ... -
Visual-lidar Map Alignment for Change Detection in Infrastructure Applications
(University of Waterloo, 2023-11-22)Current human-based infrastructure inspections face several problems. Firstly, human inspectors face safety risks working in hazardous environments and reaching challenging areas in order to inspect an infrastructure asset ... -
Visualising data distributions with kernel density estimation and reduced chi-squared statistic
(Elsevier, 2017-11-01)The application of frequency distribution statistics to data provides objective means to assess the nature of the data distribution and viability of numerical models that are used to visualize and interpret data. Two ... -
Visualization of bivariate sequence length-chain length distribution in free radical copolymerization
(Wiley, 2017-08)Copolymer properties and processability depend on copolymer microstructure, i.e., copolymer composition and monomer unit arrangements along copolymer chains. To predict ultimate properties of copolymers, one needs complete ... -
Visualizing and Understanding Code Duplication in Large Software Systems
(University of Waterloo, 2006-12-22)Code duplication, or code cloning, is a common phenomena in the development of large software systems. Developers have a love-hate relationship with cloning. On one hand, cloning speeds up the development process. On the ... -
