We consider the problem of non-rigid shape matching, and specifically the functional maps framework that was recently proposed to find correspondences between shapes. A key step in this framework is to formulate descriptor preservation constraints that help to encode the information (e.g., geometric or appearance) that must be preserved by the unknown map. In this paper, we show that considerin...

This chapter studies the H2 control problem for linear singular systems. Firstly a proportional plus derivative feedback controller for continuous and discrete cases for descriptor systems is given, satisfying the closed loop systems normal and stable states. A necessary and sufficient condition for the solvability of this problem should be obtained in terms of linear matrix inequality. In seco...

Descriptor systems constitute an important class of systems of both theoretical and practical interests and have been attracting the attention of many researchers over recent decades. This dissertation is concerned with non-standard H2 and H∞ control for linear time-invariant descriptor systems. Within the descriptor framework, the contributions of this dissertation are threefold: i) review of ...

We propose a new computational approach based on descriptor state space algorithms for computing normalized coprime factorizations of arbitrary rational matrices. The proposed approach applies to both continuousand discrete-time rational transfer-function matrices and shows that each rational matrix possesses a normalized coprime factorization with proper factors. The new method is conceptually...

Two aberrant males of Corydalus cornutus (L.) (Insecta: Megaloptera), which exhibit unusually short mandibles with discrete dentition, are recorded from a locality in Missouri. Morphological details of the specimens, as well as implications for the overall morphological variation of the genus and species are discussed. The term gynomorphic is suggested as the best descriptor of this case, given...

In this work, optimal control models subject to discrete and continuous uncertain descriptor systems are both investigated under Hurwicz criterion. At first, by employing dynamic programming method, a recurrence equation is obtained simplify the model, bang-bang problem settled according equation. Then, for an of optimality proposed testified with help uncertainty theory principle optimality, r...
