Claiming, breaking and creating : a visual response to the experience of constructed social and spatial constraints
My personal experiences of patriarchal abusive behaviour have shaped and affected me. Two things in my formative schooling years marked the beginning of deep emotional disturbances in my life. Firstly, the vulnerability of being a female schoolgirl, constantly trapped in fear by threats of …

Essays on Spatial Constraints and Gender Equality: the Impact of COVID-19 Lockdowns on Work-from-Anywhere Dynamics and Gender Equality in Job Searches
This dissertation explores the intersection of spatial constraints and gender equality by leveraging the COVID-19 lockdowns as a natural experiment to study the impact of work-from-anywhere (WFA) dynamics on job search behaviors. The introduction of mandatory lockdowns drastically shifted the labor …

High-performance evolutionary computation for scalable spatial optimization
Spatial optimization (SO) is an important and prolific field of interdisciplinary research. Spatial optimization methods seek optimal allocation or arrangement of spatial units under spatial constraints such as distance, adjacency, contiguity, partition, etc. As spatial granularity becomes finer …

Collective Motion in Spatially Heterogeneous Environments
This dissertation investigates how spatial constraints influence collective motion through agent-based modeling and empirical analysis of animal behavior. We study how obstacles affect flocking, developed an agent-based model of bat flight from experimental data, and explored a model-free …

Patterns of resource use by livestock during and after drought in a communal rangeland in Namaqualand
… patterns of rangeland use had to adapt to the spatial constraints. Descendants now herd livestock from semi-permanent stockposts that are scattered throughout the commons. Herders use a range of practices to manage their livestock. The aims of this study was to assess the agro-ecological …

A feature-based framework for evaluating synthetic human mobility
… three real-world urban datasets with distinct spatial structures. Region-specific fine-tuning enhances realism, while persistent discrepancies in multi-scale entropy coefficients reveal challenges in modeling transitions between dwell and trip states. Incorporating road network information …

Deep learning-based framework for traffic estimation for the MLK Smart Corridor in downtown Chattanooga, TN
… similarity-based trajectory method with specific spatial constraints. Finally we combined image perspective transformation with objects scaling to estimate speed with an error of 0.516 mph. Our comprehensive framework offers potential in applications like travel time estimation and benchmarking …

Non-invasive IC tomography using spatial correlations
… variations. The power (delay) variations are spatially correlated. Thus, there exists a basis in which variations are sparse. The sparse representation suggests using the L1-regularization (the compressive sensing theory). We show how to use the compressive sensing theory to improve …

New forms of Interactions in Public Spaces
… in public spaces that can escape time and spatial constraints, which means visitors coming to the space at a different time and visitors being in different physical spaces at present could still interact with each other and create a new form of collective memory. I have developed designs …

Optimization of Active Noise Control for Small Axial Cooling Fans
… surrounding the fan. Due to industry specified spatial constraints, a smaller fan and speaker configuration was desirable. The smaller configuration maintains similar control performance, further facilitating practical implementation of the control system. The smaller control system employs a …

Glia Delimit Shape Changes Of Sensory Neuron Receptive Endings in C. elegans
… changes in glial compartment size provide spatial constraints on neuronal receptive ending growth.</p>

Design of an automated cocktail mixing experience
… CAD software in order to better understand the spatial constraints and requirements of the assembly components. This model, combined with the user study and proposed user interface functionalities, serve as the foundation for the further development of the product.

Investing in youth for community well-being : the case of the Fruitvale in Oakland, CA
In this thesis I explore how youth spatially perceive their environment in the Fruitvale, an inner city neighborhood in Oakland, California. Through my fieldwork I created a visual map of how youth view their spaces in the neighborhood and what constraints are being imposed on their space with …

A subspace approach to spectral quantification for MR spectroscopic imaging
… to solving this problem, incorporating both spatial and spectral prior information. More specifically, a new signal model is proposed which represents the spectral variations of each molecule as a subspace and the entire spectrum as a union-of-subspaces. The proposed model enables an …

Optimization of Renewable Energy Siting Decisions through Vertical Axis Wind Turbine Integration
… Axis Wind Turbines (HAWTs) face deployment constraints due to their large spatial requirements stemming from their size itself and turbine spacing to accommodate wake interference. Their large footprint makes it impractical to deploy in densely populated and restricted areas, such as …

Nasal Septal Deviation and Nasofacial Skeletal Form: A Cross-Sectional CBCT Study of a 7-18 Year-Old Cohort
… anterior displacement of the sphenoid may place spatial constraints on the growth of the septum, resulting in deviation.

Design, Synthesis and Evaluation of FPR-1 Antagonists in the Treatment of Glioma
… bulky groups should be avoided due to the spatial constraints of the binding pocket. Thus, this should be the template for further studies on improving the anticancer potency of this series of compounds.
