Algorithms for flows and disjoint paths in planar graphs
… describe several algorithms for computing flows, connectivity, and disjoint paths in planar graphs. In all cases, the algorithms are either the first polynomial-time algorithms or are faster than all previously-known algorithms. First, we describe algorithms for the maximum flow problem in …

Survivable network design problems with element and vertex connectivity requirements
In this thesis, we consider degree-bounded element-connectivity Survivable Network Design Problem (Elem-SNDP) and degree-bounded Rooted k-outconnectivity Problem. We suggest bicriteria approximation algorithms that are motivated by Ene and Vakilian's work in [1] and Lau and Zhou's work in [2]. The …

Automatic mesh generation and finite element analysis of a triax dome
… The program generates nodal coordinate and element connectivity data and also has mesh refinement features. All the necessary data required for modelling the triax dome with ABAQUS is generated automatically by the program. The model of an existing triax dome at Raleigh, North Carolina, is …

Cuts and connectivity in graphs and hypergraphs
In this thesis, we consider cut and connectivity problems on graphs, digraphs, hypergraphs and hedgegraphs. The main results are the following: - We introduce a faster algorithm for finding the reduced graph in element-connectivity computations. We also show its application to node separation. - We …

Node-weighted prize-collecting survivable network design problems
… undirected graph $G=(V,E)$ and integral connectivity requirements $r(st)$ for each pair of nodes $st$. The goal is to find a minimum node-weighted subgraph $H$ of $G$ such that, for each pair $st$, $H$ contains $r(st)$ \emph{disjoint} paths between $s$ and $t$. PC-SNDP is a generalization …
