Most visual servoing applications are concerned with geometrically modeled objects. In this paper, the problem of controlling a motion by visual servoing around an unknown object with a stereovision system is addressed. The main goal is to move the end-effector around the object in order to observe several viewpoints of the object for other tasks, e.g. inspection or grasping. The present work u...

Vacuum distillation may be used to enhance the separation of hydrocarbons because of the improvement in relative volatility at the lower pressure. Vacuum may also be employed to break azeotropes by using two columns in series that operate at different pressures. And, it may be required to reduce the boiling point of the bottom composition so conventional heat-transfer fluids can be used for hea...

Let G be a properly edge colored graph. A rainbow matching of G is a matching in which no two edges have the same color. Let δ denote the minimum degree of G. We show that if |V (G)| ≥ 8δ 5 , then G has a rainbow matching of size at least ⌊ 5 ⌋. We also prove that if G is a properly colored triangle-free graph, then G has a rainbow matching of size at least ⌊ 3 ⌋.

Aharoni and Berger conjectured that in any bipartite multigraph that is properly edge-coloured by n colours with at least n + 1 edges of each colour there must be a matching that uses each colour exactly once. In this paper we consider the same question without the bipartiteness assumption. We show that in any multigraph with edge multiplicities o(n) that is properly edge-coloured by n colours ...

Let T be a torus. We prove that all subsets of T with finitely many boundary components (none of them being points) embed properly into C 2. We also show that the algebras of analytic functions on certain countably connected subsets of T are doubly generated.

Introduction: Hyaluronic acid (HA) is an anionic biopolymer composed of alternating disaccharide units of D-glucuronic acid and Nacetyl-D-glucosamine with (14)interglycosidic linkage [1]. It is the only nonsulfated glycosaminoglycan (GAG) that is abundant in the synovial fluid and extracellular matrix (ECM) [1-2]. The over all goal of this study is to fabricate and characterize nanospheres ba...

We present a mechanism for recovering consistent data from inconsistent set of assertions. For a common family of knowledge-bases we also provide an efficient algorithm for doing so automaticly. This method is nonmonotonic and paraconsistent. It is particularly useful for making diagnoses on faulty devices. Subject areas: Knowledge-based systems, Non-standard logics for AI, Reasoning under unce...
