Determining High School Geometry Students' Geometric Understanding Using van Hiele Levels: Is There a Difference Between Standards-based Curriculum Students and NonStandards-based Curriculum Students?
… curricula improve students' mathematical understanding and performance on standardized math exams. Using van Hiele levels, this study examines 20 ninth-grade students' levels of geometric understanding at the beginning of their high school geometry course. Ten of the students had been …

Energy efficient accelerators for autonomous navigation in miniaturized robots
… caves, etc. Robot perception (i.e., semantic and geometric understanding) is considered the computation bottleneck in autonomous navigation systems because of the high dimensionality of the problem. For example, multi-scale object detection is desired for robustness, which requires significant …

Root polytopes, triangulations, and subdivision algebras
In this thesis a geometric way to understand the relations of certain noncommutative quadratic algebras defined by Anatol N. Kirillov is developed. These algebras are closely related to the Fomin-Kirillov algebra, which was introduced in the hopes of unraveling the main outstanding problem of …

3D Deep Learning for Object-Centric Geometric Perception
Object-centric geometric perception aims at extracting the geometric attributes of 3D objects. These attributes include shape, pose, and motion of the target objects, which enable fine-grained object-level understanding for various tasks in graphics, computer vision, and robotics. With the growth …

Towards Object-based SLAM
… SLAM, and now there is a demand for semantic understanding of the environment beyond pure geometric understanding. This thesis delves into object-based SLAM where the map consists of a set of objects with their semantic categories recognized and their poses and shapes estimated. Such a map …

Scattering and stability properties of nonlinear wave equations on asymptotically flat spacetimes
… ones and are therefore part of a perturbative understanding of these PDEs. Furthermore, all projects are connected by the search for a geometric understanding of the equations and the use of this geometry for the analysis. The first chapter is concerned with the global behaviour of effective …
