Complete and Near-Optimal Robotic Crack Coverage and Filling in Civil Infrastructure
We present a simultaneous sensor-based inspection and footprint coverage (SIFC) planning and control design with applications to autonomous robotic crack mapping and filling. The main challenge of the SIFC problem lies in the coupling of complete sensing (for mapping) and robotic footprint (for filling) coverage tasks. Initially, we assume known target information (e.g., crack) and employ classic cell decomposition methods to achieve complete sensing coverage of the workspace and complete robot…

Undercomplete Decomposition of Symmetric Tensors in Linear Time, and Smoothed Analysis of the Condition Number
We study symmetric tensor decompositions, i.e., decompositions of the form $T = \sum_{i=1}^r u_i^{\otimes 3}$ where $T$ is a symmetric tensor of order 3 and $u_i \in \mathbb{C}^n$.In order to obtain efficient decomposition algorithms, it is necessary to require additional properties from $u_i$. In this paper we assume that the $u_i$ are linearly independent. This implies $r \leq n$,that is, the decomposition of T is undercomplete. We give a randomized algorithm for the following problem in th…

I switched to Freedom Mobile in December after being with Rogers for eons and I’m feeling like I’ve used it long enough to render a verdict. While the network isn’t as extensive as Rogers, I find it more than serviceable. And the data anxiety is gone. I was sharing 17GB monthly with my wife, and now have 50GB for myself. Now here’s why I mention this. I’ve gone pretty all out using data and barely dented my plan. Last month I used about 10GB. This month I’m probably on pace for about 15GB. 1/3

A decomposition theorem for balanced measures
Let $G = (V,E)$ be a connected graph. A probability measure $μ$ on $V$ is called "balanced" if it has the following property: if $T_μ(v)$ denotes the "earth mover's" cost of transporting all the mass of $μ$ from all over the graph to the vertex $v$, then $T_μ$ attains its global maximum at each point in the support of $μ$. We prove a decomposition result that characterizes balanced measures as convex combinations of suitable "extremal" balanced measures that we call "basic." An upper bound…
