In this paper, we study contractions of the boundary of a Riemannian 2-disc where the maximal length of the intermediate curves is minimized. Definitely my best professor of the year! Traditional thinning algorithms often have a simple, iterative structure, yet producing skeletons that are overly sensitive to boundary perturbations. We show that the problem is polynomially solvable if a and acyclic.

We prove that the problem is NP-hard in planar weighted graphs if there are upper bounds on the radii and sketch a similar proof for planar point sets. Dustin Chambers/Bloomberg/Getty Images Great Professor! A cycle on M is splitting if it has no self-intersections and it partitions M into two components, neither of which is homeomorphic to a disk. Somewhat heavy workload for an intro class, but still fair. Dr. Erin Wolf Chambers is a Professor at Saint Louis University in the Department of Computer Science, with a secondary appointment in the Department of Mathematics. In other words, splitting cycles are simple, separating, and non-contractible. We present the first algorithm to morph graphs on the torus. We describe an efficient algorithm to determine whether a given cycle in a planar Rips complex is contractible. balls of size R; put another way, there are a constant-sized subset of vertices About Me I am a Professor in the Department of Computer Science at Saint Louis University, where I also serve as associate chair, with a secondary appointment in the Department of Mathematics and Statistics.

We study the classic graph drawing problem of drawing a planar graph using In this article, we provide new structural results and algorithms for the Homotopy Height problem. In particular, we show how to compute the partition function for weighted cuts of the graph, i.e., the total weight of all (s, t)-cuts where the weight of a single cut is the product of its edge weights. I've taken Data Structures and Algorithms with her, and she was a hard, but good teacher for both of them. She will help. Given a distribution of pebbles on the vertices of a graph G, a pebbling move takes two pebbles from one vertex and puts one on a neighboring vertex. This class is (necessarily) super hard. radii is minimized. But both bounds fall short for some graphs. We discuss the relati...

We present a variant of the Fréchet distance (as well as geodesic and homotopic Fréchet distance) which forces the motion between the input objects to follow an ambient isotopy. Very passionate about the topics. Erin Chambers (born September 24, 1979) is an American actress, best known for her role as Siobhan McKenna Spencer on ABC soap opera General Hospital. She is very animated in lecture, and writes quickly, so take notes quickly and ask her to slow down when she's writing too fast. Defined elegantly as the locus of points with multiple nearest neighbors on the object boundary, the medial axis preserves both the structure and topology of the object in a compact form - a geometry that has one lower dim...

A recent result of Chepoi, Estellon and Vaxes [DCG '07] states that any I'm an international student and her speak speed a little fast but acceptable. Methods for pruning the medial axis are usually guided by some measure of significance. She has made guest appearances in a number of television shows.

She makes her only appearance in the series in episode "I Don't", but is involved in off-screen adventures twice in Series 5.Appearances and characterization []. She has made guest appearances in a number of television shows. In this paper, we consider two other parameters, the (simple) homotopy height and the (simple) grid-major height. A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Erin’s education is listed on their profile. Anyway,she is the best teacher ever! Thinning is a commonly used approach for computing skeleton descriptors. You're going to have to work to pass her classes. We prove that R(G) ≤ 4n/5, and we characterize the graphs achieving equality.

Chambers is a professor in the Computer Science department at Saint Louis University - see what their students are saying about them or leave a rating yourself.

For the case when there are no... Just over 10 years ago, we conducted a culture study of the Computer Science Department at the flagship University of Illinois at Urbana-Champaign, one of the top five computing departments in the country. Questions on the final are slightly harder than the easiest questions on the homeworks, however. Lectures are,for the most part, very clear and engaging with the class.

We describe the first algorithms to compute maximum flows in surface-embedded graphs in near-linear time. To succeed: watch each lecture twice, read each chapter thrice, and continuously bang your head against the wall. There has been considerable interest in several graph as a clique-sum of planar graphs and graphs of constant complexity is Burning the Medial Axis. We focus on computing such "interesting" topological features in three settings. In the unfavorable... We study the problems of finding a minimum cycle basis (a minimum weight set of cycles that form a basis for the cycle space) and a minimum homology basis (a minimum weight set of cycles that generates the $1$-dimensional ($\mathbb{Z}_2$)-homology classes) of an undirected graph embedded on a surface. straight-line edges with a prescribed convex polygon as the outer face. However, to date there are no Erin Chambers, Actress: Alvin and the Chipmunks. within which every other vertex is distance half the diameter. The Fréchet distance between two curves in the plane is the minimum length of a leash that allows a dog and its owner to walk along their respective curves, from one end to the other, without backtracking. Erin received a BFA in acting from Brigham Young University. While playing a fundamental role in shape understanding, the medial axis is known to be sensitive to small boundary perturbations. Cool Professor, I found the class very tough but she was always willing to help you how ever much you needed help. This method simultaneously generalizes standard persistent More precisely, given two homotopic curves $\gamma_1$ and $\gamma_2$ on a combinatorial (say, triangulated) surfac... We consider the problem of assigning radii to a given set of points in the plane, such that the resulting set of disks is connected, and the sum of radii is minimized. All rights reserved. If a structural decomposition of the In broad terms, this problem quantifies how much a curve on a surface needs to be stretched to sweep continuously between two positions. The medial axis is an important shape descriptor first introduced by Blum (1967) [1] via a grassfire burning analogy. One key strategy for reversing this de- cline is to improve methods of student retention. She is extremely helpful in office hours, but can be difficult to contact via email. erin.chambers@slu.edu. 3. Take her classes! Also she sometimes forgot update the notes. 4.6 / … Given 2 homotopic curves in a topological space, there are several ways to measure similarity between the curves, including Hausdorff distance and Frechet dis- tance.
