On the neuronal processing of movement dynamics
… four motor areas of the frontal lobe process the movement dynamics. In the experiments described, monkeys executed visually instructed reaching movements while holding the handle of a robotic arm. Motors attached to the robot allowed turning on and off perturbing forces that deviated the hand of …

Examining Movement Dynamics of the Gulf Menhaden Fishery Using an Individual-based Model
<p>This study investigates the movement and harvest dynamics of the Gulf Menhaden <em>Brevoortia patronus</em> fishery. The fishery-dependent data collected by NOAA (years 2006-2009 and 2011) describe vessel-specific information on catch locations (latitude and longitude) and magnitude of harvest …

Direct application of the least action principle to solve (human) movement dynamics without using differential equations of motion
This thesis explores the numerical feasibility of solving motion 2-point boundary value problems (BVPs) by direct numerical minimization of the action without using the equations of motion (EOM) as an intermediate step. The proposed direct least action (DLA) approach using the downhill simplex …

Deep Image Processing with Spatial Adaptation and Boosted Efficiency & Supervision for Accurate Human Keypoint Detection and Movement Dynamics Tracking
… the deep learning of human key points and movement dynamics.

Assessing environmental factors structuring populations and movement dynamics of the invasive snail Tarebia granifera in a subtropical Austral reservoir
… worldwide, but environmental drivers of invasion dynamics lack assessment. Understanding alien species ability to self-disperse via locomotion following arrival to new environments is also critical for prediction of invasion success. The study assessed: (i) the distribution and abundance of …

Investigating the Effectiveness of Supermarket Transmission Control Measures on the Spread of COVID-19 in the Presence of Super-Spreaders through Agent-Based Modelling
… for the indirect effects changes in human movement dynamics have on the spread of disease. The analysis makes use of Agent-Based Modelling simulation techniques to model changes in customer movement and disease transmission dynamics resulting from the isolated and combined implementation of …

Hybrid architecture for human action recognition using skeleton data
… enabling a comprehensive understanding of human movement dynamics. In this work, we also introduce a Cosine-based noise as a new data augmentation strategy for joints across time. This helps our model, Hybrid-Graformer, achieve accuracy comparable to the state-of-the-art across various …

Assessing Bovine Methane Emissions: Respiratory Simulation and Optical Gas Imaging Methods
… the characterization of plume intensity and movement dynamics under varying concentrations and temperatures. Quantification techniques were developed to compute a measure of breath methane content from thermal video footage. Detected methane intensity exhibited a positive linear correlation …

Racialized Fields: Asians, Mexicans, and the Farm Labor Struggle in California
… that the complex trajectory of the farm workers movement was shifted and shaped by internal and external forces emanating from landowners, the state, and within the very constituency of the movement. Therefore, I utilize sociological analysis of the historical narrative to analyze how a social …

Movement Ecology and Trophic Dynamics in the northern Gulf of Mexico: Implications for Fisheries Management
… distribution of fishing effort and the stock’s movement ecology. Fish movement was informed using <em>n</em> = 80 acoustically tagged individuals. Chapter 1 expands upon our understanding of the movement ecology of Southern Flounder and using a novel modeling approach, we evaluate management …

Detection, habitat use, and occupancy dynamics of Black-billed Cuckoos and Yellow-billed Cuckoos in Illinois
… could be due in part to wide-ranging movements within and between breeding seasons. I set out to examine detection probability, habitat use, and movement dynamics of both species. I performed passive and call-broadcast surveys for cuckoos at 41 sites throughout northern Illinois in …

Modelling and Analysis of Individual Animal Movement
Movement is ubiquitous to almost all life with most individuals undergoing some spatial change across their lifespans. Understanding how and why animals move through and interact with their environment is therefore key in understanding some of the most open and pressing questions in science; from …

Mobilization among the homeless: A comparative study of organization, action, and outcomes in eight United States cities.
… eight U.S. cities. Much of the focus of social movement research emphasizes either broad macro-level social processes or micro-level individual characteristics to understand movement dynamics. This research focuses on the organizational context and dynamics of homeless mobilization. I argue that …

Sensorimotor learning under switching dynamics
… muscle co-contraction in the learning of novel movement dynamics. We show that muscle co-contraction, as measured by surface electromyography, accelerates motor learning. We then explore the role of control points on objects in the formation of motor memories during object manipulation. We show …

Modeling of equilibrium point trajectory control in human arm movements
… representing spacing and timing, with actual movement dynamics being produced by interactions of limb inertia, muscle viscosity and speed/position feedback from muscle spindles. To counter criticisms of the EPH, investigators have proposed the use of complex virtual trajectories, non-linear …

Investigation of differences in cortical activation during wrist flexion and extension performed under real, passive and motor imagined paradigms
… force activation, sensory feedback, frequency of movement, structural and/or functional differences) might influence the cortical activation in the brain. It has been speculated that the difference in cortical muscular pathways is due to flexion movements being used more often in day to day …

Performative Interventions In Public Space: Moments of Urban Transformation in Athens
… Athens by exploring the symbiosis of corporeal movement and physical space. It initially draws attention to the political, economic and social drivers that led to the increased presence of performative activists in public space from the beginning of the financial crisis in 2008. For the purpose …

Testing for host adaptive evolution using the maize streak virus model
… and phylogeographic analyses of MSV-A movement dynamics in and out of Madagascar, Ethiopia and Rwanda using newly determined MSV-A genome sequences (Madagascar: n = 56; Ethiopia: n = 84) together with other sequences from GenBank. I showed that most movements of MSV-A into Madagascar …
