Geometric Properties of Learned Representations
… we consider the structures captured by two geometric properties of learned representations: invariances and distances. From these two perspectives, we start by thoroughly analyzing the widely adopted contrastive representation learning, uncovering that it learns certain structures and …

Geometric Properties of the Ferrand Metric
… rolling disk condition and provide a sufficient geometric condition which guarantees that the ratio of the hyperbolic and quasihyperbolic metric-densities, and also the ratio of the Ferrand and quasihyperbolic metric-densities, both approach one as an interior point approaches a boundary point.

Geometric Properties of Over-Determined Systems of Linear Partial Difference Equations
We relate linear constant coefficient systems of partial difference equations (a discretization of a system of linear partial differential equations) satisfying some collection of scalar polynomial equations to systems defined over the coordinate ring of an algebraic variety. This motivates the …

Intrinsic variations in geometric properties of nonlinear equivalent strut models for infill-RC frames
… structures. It has been found that changing the properties of an infill-frame can also change the geometric properties of struts, namely width, location and number of struts in an equivalent strut model. For this reason, recent studies have proposed a case-specific strut modelling approach. In …

Lelong Numbers and Geometric Properties of Upper Level Sets of Currents on Projective Space
… thesis, our goal is to understand more about the geometric properties of the sets of highly singular points of the current $T$. Lelong numbers will be the main tool used for determining how singular a point of a current is. For the first main result of this thesis, we let $T$ be a positive closed …

The effects of selected corn-soybean tillage systems on rill cross-sectional geometry and soil erosion for two Illinois soils
… soil conditions and to relate variations in rill geometric properties to measured sediment discharge and to soil erosion and sediment transport predicted by various models. In the experimental phase of this study, simulated rainfall and additional run-on water were applied to plots that had been …

Investigation of regional variation in Lunar crater morphometry from (Lunar Orbiter Laser Altimeter) LOLA observations
… into 50 elevation profiles, from which key geometric crater properties are extracted. The geometric properties and their respective standard variation, such as height-to-diameter ratios, and average elevation profile are compared on a global level to investigate regional differences in …

Geometric methods for optimal resource allocation in wireless network localization
… a point in 3-D Euclidian space. By exploiting geometric properties of these image points, we prove the sparsity property of the optimal resource allocation vector, i.e., the optimal localization performance can be achieved by allocating resources to only a small subset of neighboring nodes. …

Selection from a hierarchical world of uniform connected regions
… is presented, which suggests that basic geometric properties of visual stimuli provide the definition and organization of objects, and that these objects are the candidates for attentional selection. The theory suggests that uniform connected (UC) regions, which are contiguous surfaces of …

Ample subschemes and partially positive line bundles
A common theme in algebraic geometry is that geometric properties of an algebraic variety are reflected in the subvarieties that are 'positively embedded' in it. Here the case of subvarieties of codimension one is classical and also fundamental to algebraic geometry: divisors correspond to line …

Geometry of compositionality
… This thesis further explores the interesting geometric properties of word embedding, and looks into its interaction with the context representation. We propose an innovative method to detect whether a given word or phrase is used literally in a specific context. This work focuses on three …
