Design of a constraint device for compliant bodies using quasi-conformal contact surfaces as applied to mouse imaging
… of this work is the modeling and prototyping of quasi-conformal constraint contacts and the investigation of their positioning ability for compliant bodies, specifically for the holding of mice in optical imaging setups. The direct application of this work is the restraint of laboratory mice for …

Shape analysis in shape space
… are proposed. </p> <p>In the first method, a quasi conformal shape space is constructed based on a novel quasi-conformal metric, which preserves the curvature changes at each vertex during the deformation. Besides, a classification framework is introduced for deformation classification. The …

Quadrilateral Remeshing and Efficient Surface Parameterization
… describe a new iterative method for constructing quasi-conformal parameterizations with free boundaries. We formulate the problem as fitting the coordinate gradients to two guidance vector fields of equal magnitude that are everywhere orthogonal. In only one linear step, our method efficiently …

Quasiconformal Groups
In this thesis the notion of Schottky quasiconformal groups is introduced. We study Schottky quasiconformal groups and show that the limit set L(G) of any Schottky quasi-conformal group G is uniformly perfect. Then the concept of Schottky-type quasiconformal groups is introduced, and we generalize …

Advances in Complex Electromagnetic Media
… a numerical scheme could be employed to find quasi-conformal transformations for which the requisite complex material distribution could be well approximated by an isotropic, inhomogeneous media. This process was previously used to demonstrate a carpet cloak-a device which masks a bump in a …

Geometric mapping theory of the Heisenberg group, sub-Riemannian manifolds, and hyperbolic spaces
… After discussing homotheties and conformal mappings of $\Heis^n$, we show the convergence of base-$b$ and continued fraction expansions of points in $\Heis^n$, and discuss their dynamical properties. We then generalize to sub-Riemannian manifolds and their quasi-conformal and …

Geometric Computing beyond the Laplacian
… numerical schemes to search for the metric or conformal structure whose associated (generalized) Laplacian is optimal for a given task, or explicitly design operators as suggested by modern spectral geometry. Concretely speaking, to represent an arbitrary diffeomorphism or injective map that is …

Complex-Analytic Methods in Reconstructive Integral Geometry
… formula as well as some results on quasi-conformal mapping theory. These results are used in establishing a stability estimate on a natural generalization of this polynomial space in real-analytic functions in an attempt to address approximation/truncation concerns. Finally, we take …

Subdivision and manifold techniques for isogeometric design and analysis of surfaces
… differential-geometric manifold techniques with conformal parametrisations and the partition of unity method. This thesis derives novel manifold-based basis functions with arbitrary prescribed smoothness using quasi-conformal maps, enabling us to model and analyse surfaces with sharp features, …
