Invariance Entropy of Control Sets
Invariance entropy for continuous-time control systems measures how often openloop controls have to be updated in order to render a compact and controlled invariant subset of the state space invariant. A special type of a controlled invariant set for a control-affine system is the closure of a control set, i.e., a maximal set of approximate controllability. In this paper, we investigate the pro...
متن کاملSpecifying Weak Sets
We present formal speci cations of a new abstraction weak sets which can be used to alleviate high latencies when retrieving data from a wide area in formation system like the World Wide Web In the presence of failures con currency and distribution clients performing queries may observe behavior that is inconsistent with the stringent semantic requirements of mathemat ical sets For example an e...
متن کاملMotivation for Weak Sets
Suppose you are browsing the World Wide Web (WWW) and want to display the .face les of all people listed on Carnegie Mellon's home page. Or, suppose through the on-line library information system (LIS) you want to get a list of papers by a particular author. Or, suppose you are a tourist in Pittsburgh and want to look at the on-line menus of all Chinese restaurants before choosing where to eat ...
متن کاملReconstruction of Decomposable Discrete Sets from Four Projections
In this paper we introduce the class of decomposable discrete sets and give a polynomial algorithm for reconstructing discrete sets of this class from four projections. It is also shown that the class of decomposable discrete sets is more general than the class S ′ 8 of hv-convex 8but not 4-connected discrete sets which was studied in [3]. As a consequence we also get that the reconstruction fr...
متن کاملWeak Convergence of Random Sets
In this paper the classical Portmanteau theorem which provides equivalent conditions of weak convergence of sequence of probability measures is extended on the space of the sequence of probability measures induced by random sets.
