Learning two-dimensional spatial dynamics from experimental data
This thesis discusses the analysis of complex spatial dynamics using a computer learning algorithm. The goal is to model experimental data, the dendritic solidification of ammonium bromide crystals, using a learning algorithm to search through a space of possible models in order to find an optimal …

Parental choice in secondary education : socio-spatial dynamics and motivation
… area. Second, to identify the extent of socio-spatial variation of patterns and trends in choice of school. Secondary school transfer data relating to over 16,000 children for 1991 and 1993 to 1995 was analysed in a Geographical Information System (GIS). One hundred and sixty two parents of …

Spatial Dynamics and the Mechanoresponse in CD4+ T Cell Activation
… The work in this dissertation highlights the spatial and temporal dynamics that regulate the initial coupling of CD28 with TCR signaling and also dissects the mechanical properties conferred by downstream effectors that are required to relay CD28 costimulation. A reaction-diffusion model that …

Effect of soil structure on temporal and spatial dynamics of bacteria
… is how soil structure affects the temporal dynamics and spatial distribution of bacteria. Using repacked microcosms, the effect of bulk-density, aggregate sizes and water content on growth and distribution of introduced <i>Pseudomonas fluorescens</i> and <i>Bacillus subtilis</i> bacteria was …

An Experimental Evaluation of the Experimental Spatial Dynamics Modeling (ESDM) Technique
… An important new technique, Experimental Spatial Dynamics Modeling (ESDM), utilizes such spatially dense velocity data. ESDM models continuous, three-dimensional velocity fields using LDV velocity data. Thus, ESDM is a powerful structural dynamics analysis tool that significantly enhances …

Gothic Views, Romantic Visions: The Spatial Dynamics of Modern Art and Literature
… exchange, indeed a symbiosis, between the spatial and visual principles of the Gothic Revival and the aesthetics and values of Romanticism. This cross-fertilization occurs in four key areas--the spontaneous expression of emotion, the direct contact with nature, the primacy of the …

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 dynamics modeling for data-poor species using examples of longline seabird bycatch and endangered white abalone
Spatial analysis of species for which there is limited quantity of data, termed as the data-poor species, has been challenging due to limited information, especially lack of spatially explicit information. However, these species are frequently of high ecological, conservation and management …

Development of the Velocity Transformation Function of Damped Flat Shell Finite Element for the Experimental Spatial Dynamics Modeling
Experimental Spatial Dynamics Modeling (ESDM) is the new process of constructing a three dimensional, complex-valued dynamic model of a harmonically vibrating structure using numerical models and laser-based experimental data obtained from a Scanning Laser Doppler Vibrometer (SLDV). In ESDM …
