Convergence rate of overlapping domain decomposition methods for the Rudin-Osher-Fatemi model based on a dual formulation by Chang, Huibin, Tai, Xue-Cheng, Wang, Li-Lian, Yang, Danping

“…We introduce a stable “unity decomposition” using a set of “partition of unity functions,” which naturally leads to overlapping DDMs based on the dual formulation. The main objective of this paper is to rigorously analyze the convergence of the SSC and PSC algorithms and derive the rate of convergence $O(n^{-1/2})$, where $n$ is the number of iterations. …”

Understanding campus mobility by Toh, Christopher Gerard Wei Hong

“…To begin with, an exploratory study on mobility patterns on campus, looking at spatial and temporal aspects of mobility. A main finding would be that the arrival rate of people on campus increases at a faster rate, with counts peaking between 1100H and 1300H, before decreasing at a gradual rate thereafter. …”
