Pilgrimage, Spatial Interaction, and Memory at Three Marian Sites
… three places are porous in that they emplace the interactions of different groups, fostering the permeability of boundaries between categories of pilgrimage and tourism, commercial place and devotional place, and cultural and spiritual value. They also show varied degrees of spatial porousness, …

SHVIL, PLANWELL, & FLYING FRUSTUM: Spatial Interaction With 3D Physical Maps
Spatial representations are crucial when people interact with the physical environment. For example, geographic maps are one of the primary sources for way-finding, spatial planning and navigational activities. Recent technological advancements enable the evolution of current 2D interactive spatial …

Commuting flows & local labour markets: Spatial interaction modelling of travel-to-work
… of employment, housing, and the many spatial processes underlying commuting. However, in order to understand the commuting process, it is important to examine the milieu within which commuting takes place: the local labour market (LLM). In this thesis, the interplay between commuting …

Modeling Regional Spatial Interaction Under the Condition of Limited Information: A Comparative Analysis
… use of econometric models to measure space-time interactions was proven to be fruitful, even at a very aggregated level. Nevertheless, it would also be interesting to include economic sectors in the analysis, so that would be possible to exactly pinpoint the most spatially integrated sectors in …

Regional Variations in Polish Peasant Farm Efficiency: Composed Error, Spatial Econometric and Spatial Interaction Techniques
The objective of this analysis was to compare analytical methods as well as to highlight the most important issues for the continued rural impoverishment in Polish peasant farming. This situation is particularly relevant, given the policy implications for Poland's impending European Union …

Contributions to modeling and computer efficient estimation for Gaussian space -time processes
… class of computer-efficient Gaussian spatial interaction models that includes as special cases CAR and SAR-like models. This extended class is capable of modeling smooth spatial random fields. We show that, for rectangular lattices, this class is equivalent to higher-order Markov …

Inverse Problems in Agent-Based Models of Spatial Phenomena
… matrix (ODM) of agent trip counts between spatial locations, given low-resolution summary statistic data. This problem is ill-posed, as the space of ODMs consistent with the observed data is combinatorially large. In its continuous mean-field limit, the ODM is governed by a stochastic …

Design of spatial interfaces for engineering assembly within a virtual environment for automotive design
… studies on the design of a novel two-handed spatial interface for engineering assembly, informed by a number of qualitative studies using a realistic assembly model within a fully working virtual environment (VE). The results show that the two-handed spatial interface has the potential to …

The geographical data science of population flows
This research seeks to address the issues of spatial structure and counter intuitive findings in modelling population movements. Previous research based on interaction data for census administrative boundaries indicates urban – rural patterns in the propensity to travel which are exasperated in …

Imaginary Interfaces
… devices also abandon the currently dominant spatial interaction style (such as tapping on buttons), because, seemingly, there is nothing to tap on. Unfortunately this design prevents users from transferring their learned interaction knowledge gained from traditional touchscreen-based devices. …

Miles Matter: Demographics, Distance, and Decision-Making
… three-pronged methodology consisting of spatial (time and distance analysis complemented by a spatial interaction model), statistical (multinomial logistic regression model), and machine learning-based (graph neural networks and extreme gradient boosting) analysis, I explore the …

Wetland landscape dynamics and its socio-ecological implications
… grouping imagery into objects to preserve the spatial, spectral, and temporal scale. Two classification algorithms support vector machine (SVM) and K-Nearest Neighbor (K-NN) were used. The second part involved deriving secondary terrain attributes using the compound topographic index (CTI) and …

Modeling Complex Forest Ecology in a Parallel Computing Infrastructure
… discuss the development efforts to incorporate spatial interaction and succession dynamics into the model. To evaluate the performance of our implementation, an extensive set of simulation experiments was carried out using a dataset representing the H.J. Andrews Forest in the Oregon Cascades. …

Spatial dynamics of microbial populations driven by social interactions and horizontal gene transfer
… microbial ecosystems are closely related to the spatial structures formed by microbial communities. Yet, it is not well understood what determines, controls and regulates the spatial dynamics of microbial populations. In this study, we use synthetic microbial consortia as our experimental models, …

Spatial peripheral interaction techniques for viewing and manipulating off-screen digital content
… explores the design and evaluation of several spatial off-screen exploration techniques that make use of the interaction space around the display. These include Paper Distortion, Dynamic Distortion, Dynamic Peephole Inset, Spatial Panning, and Point2Pan. We also contribute a formalized …

Waterworks : an artist's inquiry into the development of spaces that promote creative interaction
… of environments that promote creative interaction. The term "creative interaction" as it will be used within the context of this thesis refers to a dynamic relationship in which an individual(s) responds to the environment with a well integrated sense of exploration, introspection and …

Two Papers of Financial Engineering Relating to the Risk of the 2007--2008 Financial Crisis
… crisis. In the first part, we construct the Spatial Capital Asset Pricing Model and the Spatial Arbitrage Pricing Theory to characterize the risk premiums of futures contracts on real estate assets. We also provide rigorous econometric analysis of the new models. Empirical study shows there …

Spatial competition and nonlinear responses in marketing
Spatial competition, in the context of industry-wide changes in retailing formats and strategies, is addressed in this dissertation from a theoretical modelling perspective. Chapter2 develops a normative individual choice model to explore how "power retailers" affect grocery shopping behaviour, …

Collaborative Augmented Reality
… time. It increases the sense of collaborative spatial interaction without requiring complex infrastructure. Assuming the given low level communication and AR libraries have modular structures, the proposed approach is also modular and flexible enough to adapt to their requirements without …
