Hybrid System Identification of Manual Tracking Submovements in Parkinson's Disease
Seemingly smooth motions in manual tracking, (e.g., following a moving target with a joystick input) are actually sequences of submovements: short, open-loop motions that have been previously learned. In Parkinson's disease, a neurodegenerative movement disorder, characterizations of motor …

Variations in Control and Display Gain in a First Control Order Compensatory Manual Tracking Task
… many factors that contribute to the optimal manual control of a system by a human operator (HO). Two such variables include control gain and display gain. Of particular interest to the following experiment is the contribution of these two variables to the manual tracking performance of any HO …

Effects of seated posture on static strength, lower-body isometric muscle contractions, and manual tracking performance
… straining maneuvers (AGSMs); and (3) tracking performance for a manual tracking task. The purpose of this research is to determine if certain body postures significantly affect force generation, isometric muscle contractions, and tracking error. Subjects perform three different tasks …

Empirical Studies Concerning Aural Alerts for Cockpit Use Leading to an Aural Alerting Signal Categorization Scheme
… task in conjunction with an automated and manual tracking task. Sound identification data revealed that subjects correctly identified the alerting set (i.e., major flight deck function) and urgency level associated with each of 12 aural alerts in 96.53% of the trials occurring during …

Extreme wave impact on a flexible plate
… data on the water and the plate simultaneously. Manual tracking of the wave front and Particle Image Velocimetry (PIV) were used to gather water height, wave speed, crest speed, vorticity, and particle speed, which were used to determine the pressure exerted by the water on the plate. An …

Leveraging distributional context for safe and interactive data science at scale
… development, while not requiring error-prone manual tracking of reusable intermediates; (ii) for visualization search, we develop context-aware sampling algorithms that support interactive search for patterns in visualizations, while ensuring that the results meet rigorous quality guarantees; …

Bacteria - Hydrogel Interactions: Mechanistic Insights via Microelastography and Deep Learning
… of bacteria behavior in hydrogels requires tracking of thousands of individual cells. Thus, there is an unmet need to develop new automated techniques to reduce the labor-intensive manual tracking of bacteria in low-contrast hydrogel environments, with feature sizes comparable to that of …

Transfer of Skill From a Computer -Based Training Program to Driving in a Simulated Environment
… memory, visual attention, decision making, manual control and other cognitive abilities are involved in safe driving. Age-related declines in these abilities may contribute to this risk as driving is a complex task which taps these and other abilities. Training improves performance on these …

Modeling the control of visual attention in complex workspaces
… performed a central highway-in-the-sky (HITS) manual tracking task and a peripheral alert detection task concurrently while alert eccentricity, salience, expectancy, and central task workload were manipulated. The results of the studies suggested two primary design recommendations: 1) Critical, …

Automatic Cell Tracking For Studying Large Epithelial Sheets Of Cells And Its Application To Chicken Gastrulation
… from the acquired volumetric image sequences. Manual tracking and segmentation of all the individual cells from the embryo wide image sequences is unfeasible. To solve this problem, we developed algorithms to segment cell membranes and to automatically track each individual cell during …

Scale-up behavior of the froth stability measurement
… were done on an industrial scale by means on manual tracking of froth growth versus time. Pulp bubble size experiments was performed on a laboratory scale by using different pore size glass frits while maintaining a constant superficial gas velocity. Dynamic stability for the pulp bubble size …

Characteristics of muscle co-contraction during isometric tracking
… coordination and the performance of a simple manual tracking task. The study employed an isometric, zero order, pursuit tracking task with a laterally translating, periodic sine wave forcing function. The speed of the target was varied by altering the Frequency (3 levels) of the simple sine …

Glacier surging in the West Kunlun Shan
… decadal-scale range of remotely sensed imagery, manual tracking of terminus position change, and cross-correlation feature-tracking methods are used to identify and characterise surge dynamics in the range. A total of ten glaciers were observed to surge between 1972–2016 – 11.3% of the total …
