Joint Face Detection and Tracking in Three-Dimensional Space
Visual detection and tracking of faces in complex scenes is a very interesting and challenging problem. In general, real human-computer interaction scenarios present significant challenges to most face detection and tracking algorithms, for example, partially occluded and low-resolution faces, as …

Conformal Flight Path Symbology for Head-Up Displays: Defining the Distribution of Visual Attention in Three-Dimensional Space
… was found to be more widely distributed in X-Y space when the pilots were flying with the conformal, tunnel-in-the-sky as compared to the partially conformal ILS (instrument landing system) symbology set. There was little evidence that the air-based navigation displays were supporting divided …

A deterministic surface estimation algorithm using parametric line equations
… Given a network of scattered data in the three-dimensional space, we use the Delaunay's Triangulation Method to connect the given points with triangles, subsequently we use out method to interpolate within the path defined by each triangle. The resulted patches have geometric continuity, …

Two-Component Link Symmetries
A mathematical knot is a closed curve in a three-dimensional space that does not intersect itself, while a link is two or more such curves that do not intersect each other. We consider the ``intrinsic'' symmetry group of a two-component link L which records directly whether L is isotopic to a link …

A cubic and bicubic method for curve and surface estimation
… estimated, based on a given set of data in the three dimensional space, has a continuous first or second derivatives. The given data does not have to be equidistant. Also, since the method leads to parametric equations for the patches of the surface, the estimating surface does not need to be a …

A Proposed Numerical Method for the 3D Wave Equation with Constant Speed
… (classical) constant speed wave equation in the three dimensional space, currently existing methods (even if more restrictive) rely on time iterations and observe the accumulation of error at each time step iteration, the new method is iteration free ! Making it a good choice for applications …

Blade geometry description using B-splines and general surfaces of revolution
… be met. The process of mapping curves from two-dimensional space to three-dimensional space is described in detail. All the algorithms are designed to work with B-spline curves (and in some cases NURBS curves) and produce a B-spline surface for the blade.</p>

Shapes and implementations in three-dimensional geometry
… is in its abstract form a finite point set in space, and it is often useful or required to compute what one might call the ""shape"" of the set. For that purpose, this thesis deals with the formal notion of the family of alpha shapes of a finite point set in three-dimensional space. Each shape …

High Performance Power Converter Systems for Nonlinear and Unbalanced Load/Source
This dissertation covers three levels of issues and solutions dealing with unbalanced and/or nonlinear situations in power electronic systems, namely power converter level, power converter system level, and large-scale power electronics system level. At power converter level, after review of …
