Saliency Deficit and Motion Outlier Detection in Animated Scatterplots
(Association for Computing Machinery, 2019-05-04)We report the results of a crowdsourced experiment that measured the accuracy of motion outlier detection in multivariate, animated scatterplots. The targets were outliers either in speed or direction of motion, and were ... -
Scalable immersive audio for virtual environments
(2018-05-01)This thesis discusses the history of game sound and how it developed to become increasingly more immersive and realistic by accounting for the spatial aspects of sound. It then compares several 3D sound technologies before ... -
Scalable subgraph representation learning through simplification
(2023-06-01)Link prediction on graphs is a fundamental problem. Subgraph representation learning approaches (SGRLs), by transforming link prediction to graph classification on the subgraphs around the links, have achieved state-of-the-art ... -
Secure and privacy-preserving fog-assisted vehicular crowdsensing
(2018-08-01)Vehicular crowdsensing (VCS) is an emerging paradigm where vehicles use onboard sensors to collect and share data with the aim of measuring phenomena of common interest. VCS has allowed for automated control as well as ... -
A secure and privacy-preserving incentive framework for vehicular cloud
(2018-04-01)Vehicular Cloud Computing (VCC) plays a critical role in data generation where a large number of vehicles collect various kinds of sensing resources with large-volume features. While the information that should be collected ... -
SegmentPerturb: effective black-box hidden voice attack on commercial ASR systems via selective deletion
(2021-08-01)Voice control systems continue becoming more pervasive as they are deployed in mobile phones, smart home devices, automobiles, etc. Commonly, voice control systems have high privileges on the device, such as making a call ... -
Self-healing solutions for LTE evolved packet core
(2012-10-01)The 3GPP Long Term Evolution (LTE) is considered as a dominant future cellular wireless technology in terms of performance and user experience. With technological advancement of the wireless networks, dependencies and ... -
Sex and seasonal variation in hippocampal volume and neurogenesis in the eastern chipmunk, Tamias striatus
(2015-07-01)The hippocampus (HPC) is important in spatial memory and navigation and also exhibits adult neurogenesis. In wild-living species, HPC volume and neurogenesis have been found to differ between the sexes and vary seasonally ... -
Silence of the fish: injection of photoswitchable short interfering RNA oligonucleotides into Japanese medaka embryos (oryzias latipes) to photochemically control gene silencing
(2023-12-01)The siRNA duplex functions by binding to and cleaving mRNA, a process known as the RNAi pathway. Existing siRNAs face challenges such as off-target effects and unpredictable prolonged gene-silencing. To address these issues, ... -
Simulating a virtual drilling task using audio, visual, and mouse movement cues during the COVID-19 pandemic
(2021-04-01)This work examined whether a real-world drilling task can be successfully simulated using combinations of appropriate audio, visual cues, and basic haptic stimuli obtained with mouse movements instead of a haptic device. ... -
Simulation and modelling to develop a nanopore-based device for ricin detection
(2022-08-01)Nanopore-based protein detection represents an exciting opportunity to develop ultrasensitive diagnostic devices that are both portable and affordable. Aptamer-encoded nanopores detect target molecules by binding to them ... -
Single copy gene expression system as a tool for the purification of membrane proteins from Pseudomonas aeruginosa
(2011-08-01)Pseudomonas aeruginosa is a Gram-negative opportunistic human pathogen known to cause a variety of infections that are difficult to treat due to extremely high resistance to almost all antibiotics currently in clinical ... -
Single magnetic resonance image super-resolution using generative adversarial network
(2022-08-01)Super-Resolution is the process of converting given low-resolution images into corresponding high-resolution ones. The resolution enhancement process applied to medical images can potentially improve diagnostic accuracy ... -
Spatial and temporal assessment of rural-urban land-use gradient effects on water quality and periphyton communities in tributaries of Durham Region, Ontario
(2016-08-01)This study examines the effects of longitudinal and local land-use gradients on water quality and periphyton within four watersheds representing varying rural-urban land-use types and intensities. Although numerous studies ... -
Spatial peripheral interaction techniques for viewing and manipulating off-screen digital content
(2015-08-01)When an information space is larger than the display, it is typical for interfaces to only support interacting with content that is rendered within its viewport. To support interacting with off-screen content, our work ... -
Spatial sound and sound localization on a horizontal surface for use with interactive surface (tabletop) computers
(2012-08-01)Tabletop computers (also known as surface computers, smart tables, and interactive surface computers) have been growing in popularity for the last decade and are poised to make in-roads into the consumer market, opening ... -
Spring Stepper: a makerspace controller for seated hands-free locomotion in virtual reality
(2019-12-01)Natural locomotion is crucial for improving presence in a virtual environment (VE), while also reducing simulator sickness. While research in various areas of virtual reality (VR), such as head-mounted displays (HMD) and ... -
