Robust control of polytopic systems by convex optimization
— Robust control synthesis of linear time-invariant SISO polytopic systems is investigated using the polynomial approach. A convex set of all stabilizing controllers for a polyto...

Optimization problems in multiple subtree graphs
We study various optimization problems in t-subtree graphs, the intersection graphs of tsubtrees, where a t-subtree is the union of t disjoint subtrees of some tree. This graph cl...

A fast and efficient algorithm for low-rank approximation of a matrix
The low-rank matrix approximation problem involves finding of a rank k version of a m ? n matrix AAA, labeled AAAk, such that AAAk is as "close" as possible to the best ...

An Efficient Boundary Encoding Scheme which is Optimal in the Rate-Distortion Sense
In this paper, we present a fast and optimal method for the lossy encoding of object boundaries which are given as 8-connect chain codes. We approximate the boundary by a polygon ...

Optimal Control of Production Systems with Unreliable Machines and Finite Buffers
In this paper we present a novel formulation for the optimal control of discrete event dynamic processes which represent production systems with unreliable machines and buffers of...
