Shape analysis in shape space
… to classify different deformations based on the shape space concept. A shape space is a quotient space in which each point corresponds to a class of shapes. The shapes of each class are transformed to each other by a transformation group preserving a geometrical property in which we are …

Combining Probabilistic Shape-from-Shading & Statistical Facial Shape Models
… present an approach to combine a probabilistic Shape-from-Shading algorithm with statistical models of facial shapes. Thesis presents how Fisher-Bingham (FB8) distributions are sampled using Gibbs sampling to give normal distributions on the tangent plane. These normal distributions are in turn …

Protein Shape Description and its Application to Shape Comparison
… specifically, by using the structure density-map shape similarity instead of sequence or model similarity. Therefore, this project introduces a mathematical framework for computing three different measures of macromolecular three-dimensional shape similarity and demonstrates how these descriptors …

NOVEL SHAPE MEMORY AND MULTI-SHAPE MEMORY POLYMERS FOR BIOMATERIAL APPLICATIONS
… natural environment. In this work, advanced shape memory polymers (SMPs) that respond to non-thermal triggers and multi-shape memory materials capable of multiple topographical transitions were developed for advanced active cell culture platforms. </p> <p> The first part of this dissertation …

From Cell Shape to Body Shape: Epithelial Morphogenesis in Drosophila melanogaster
… accumulation. In addition, we describe the cell shape changes that lead to the formation of segmental grooves, and take a genetic approach to characterize the role of DRhoGEF2 and the Rho1-effector Diaphanous (Dia) in this process. Both DRhoGEF2 and dia are required for groove formation. However, …

Impact of turbulence models and shape parameterization on robust aerodynamic shape optimization
… and Menter's Shear Stress Transport) and shape parameterization techniques (Hicks-Henne bump functions, B-Spline curves and Free-Form Deformation) on the computational cost, optimal shape, and its performance obtained with robust optimization under uncertainty. The effect of changing the …

Shape memory polymers with improved shape recovery properties in focused ultrasound fields
Shape memory polymers (SMPs) have garnered significant attention for their remarkable ability to recover deformations upon external stimulation, making them highly suitable for biomedical devices, soft robotics, and deployable systems. Among the various activation mechanisms, focused ultrasound …

Digital fabrication of shape
Im Moment befinden wir uns im Übergang vom Zeitalter der Massenproduktion in eine Welt der individuellen Fertigung. Dieser Übergang wird durch die Verbreitung von 3D Druckern ermöglicht, welche die Art und Weise wie wir Produkte entwerfen, entwickeln, fertigen und konsumieren, revolutionieren …

Shape Optimization of Hydrofoils
… thesis, a genetic algorithm: GA) is employed for shape optimization of hydrofoils for application in a sailing craft. The hydrofoil for a sailing craft should have high lift at lower speeds and low drag at higher speeds. Computations are performed for a hydrofoil in deep water as well as one close …

Shape Analysis in Bioinformatics
… that pesticide toxicity is related to the shape similarity between the pesticide molecule itself and the natural ligand of the protein to which a pesticide will bind (and ultimately cause toxicity). A ligand of aprotein is simply a small molecule that will bind to that protein. It seems …

The Shape of Things
<p><em>The Shape of Things</em> is a collection of stories that investigates girlhood and womanhood through women’s bodies, particularly as the body affects their roles in families and relationships and leads to higher risks of becoming victims of violence. These stories show characters navigating …

Color/Shape/Form/Space
Color/Shape/Form/Space begins at its title. The show is named with the same directness that I want the work to have: accessible, ready for consumption. Stripped of unnecessary information, the exhibition’s title needed to match the work itself, which expresses minimalistic tendencies, avoiding the …

Smooth Shape-restricted Regression
Estimation of a function under shape restriction is of considerable interest in many practical applications. It is not uncommon that in many elds, researchers are in the position of having strong presumptions about certain relationships satisfying qualitative restrictions, such as monotonicity and …

Voxel-space shape grammars
… One such area of Procedural Generation is Shape Grammars, a type of formal grammar that operates on geometric shapes instead of symbols. Conventional shape grammar implementations use mesh representations of shapes, but this has two significant drawbacks. Firstly, mesh representations make …

Events that shape genomes
The invention and development of Next Generation Sequencing has opened up new possibilities for exploring the genomes of non-model organisms. For this thesis, a diverse range of non-model species from both plants and animals were used to identify and answer questions of evolutionary interest in …

The shape of shadows
This is a woman's journey backwards to her people and her place, taking her into deep memory and reconstruction of memory; and yielding moments of darkness she knows she must face, though she is hardly able. It is focused on her need to know her grandmother, and to understand her father's suicide …

Granular Shape Memory Ceramics
Shape memory ceramics (SMCs) are burgeoning functional materials based on zirconia with a reversible, stress-inducible martensitic phase transformation. Compared to metallic shape memory alloys, SMCs have broader operating temperatures, higher critical stresses, and larger mechanical hysteresis …

Aging and Stereoscopic Shape Perception
… and younger observers' ability to perceive the shape of stereoscopic surfaces. In this experiment, four different surfaces defined by disparity (i.e., bumps, saddles, vertical cylinders, and horizontal cylinders) were shown to five younger (i.e., 30 and below) and five older (i.e., 60 and above) …

Integrating Shape-from-Shading & Stereopsis
This thesis is concerned with inferring scene shape by combining two specific techniques: shape-from-shading and stereopsis. Shape-from-shading calculates shape using the lighting equation, which takes surface orientation and lighting information to irradiance. As irradiance and lighting …
