Approximation of LQR-Problems for Delay Systems: A Survey,ow has reached a degree of maturity which justifies a survey on the main results obtained so far. Because of limitations in space (for these proceedings) and in time (on the author’s side) it is not our intention to give a complete survey (and correspondingly a complete list of references). We rathe

Identification of Microscopic Flaws Arising in Thermal Tomography by Domain Decomposition Method,often occur in passenger airplanes or space flight systems. The purpose of the method is to detect cracks inside a material rapidly and nondestructively by analyzing thermogra.phical data collected from the front surface of the material. Figure 1.1 ilLustrates this thermal technique using the infrar

A function x E W’”P([to,t1],IR’’) can be characterized via the Sobolev imbedding theorem as being absoLutely continuous with its first derivative being in LP([to,t1],lKn). Our attention shall be confined to the case 2 < p < oo, and freque

Some Partial Differential Equations Arising in Nonlinear Control and Optimization,and center manifold theory provides a local existence theory. In the linear case, this Sylvester equation was studied by Hautus [.] who proved that well-posedness is equivalent to the assertion that no system Transmission zero be a natural frequency of the exosystem which produces signals to be trac

For these reasons, computational mathematics is mov­ ing to the forefront in recent developments in m
