Using Cartan's Method of Equivalence, we prove an upper bound for the generality of generic rank-1 Backlund transformations relating two hyperbolic Monge-Ampere systems. In some cases, we obtain… (More)

Classically, given a surface $S\subset \mathbb{E}^3$ with constant Gauss curvature $K<0$, one can generate a 1-parameter family of surfaces with the Gauss curvature $K$ by solving only ODEs. This is… (More)

In this project, we study the network activation problem on planar graphs. In particular, we obtain a polynomial-time constant-approximation primal-dual algorithm for the Steiner forest activation… (More)

Aiming at the problems of poor tracking accuracy, inadequate anti-jamming ability and unavoidable monitoring unreachable angle in the traditional tracking method of four-rotor unmanned aerial vehicle… (More)

To each dynamic equivalence of two control systems is associated an infinite permutation matrix. We investigate how such matrices are related to the existence of dynamic equivalences.

The main topics of this lecture are the offline edge-weighted Steiner tree and Steiner forest problems. The former generalizes the minimum spanning tree problem by requiring connectivity of a subset… (More)

In this lecture, we start introducing the randomization of (undirected) graphs. Given a graph G = (V,E), one can consider the following two operations: • Edge contraction: randomly pick an edge, then… (More)

Silver-coated molybdenum is an optimum material selection to replace pure silver as solar cell interconnector. However, the low adhesive strength between Ag films and Mo substrate hinders the… (More)
