This paper considers the problem of application-level QoS control in group collaboration systems. The QoS parameters considered, latency, jitter, packet-loss, and asynchrony, are controlled by the receiver. The QoS control is based on a novel protocol composition-based approach, wherein the protocol is modularized such that each module controls a single QoS parameter. Each module is then assign...

Most learning systems applied to problem solving have the goal of learning knowledge for solving problems more eeciently. However, very few systems have focused on the acquisition of planning operator descriptions. In this paper, we present a system that learns operator deenitions from the interaction with a completely unknown environment. In order to achieve better learning convergence, severa...

In this paper, we argue that different levels of knowledge are involved in the representation of clinical guidelines, and that distinguishing among these levels is important from both the conceptual and the methodological point of view. In particular, at the epistemological level, one points out different types of actions and distinguishes between structural relations and control relations. On ...

We introduce the notion of a strongly homotopy-comultiplicative resolution of a module coalgebra over a chain Hopf algebra, which we apply to proving a comultiplicative enrichment of a well-known theorem of Moore concerning the homology of quotient spaces of group actions. The importance of our enriched version of Moore’s theorem lies in its application to the construction of useful cochain alg...

Industrial training is an emerging applicative domain for virtual reality. GVT (Generic Virtual Trai-ning) is a platform to create virtual environments for individual training on industrial procedures suchas maintenance procedures. Nevertheless, industrial needs keep on evolving and a new request concernstraining on collaborative procedures. In this thesis, we propose models to exte...

Interestingly, mechanism of toxic action on some target organs drugs and other substances proceedings of the european society of toxicology meeting held in berlin west june 25 28 1978 that you really wait for now is coming. It's significant to wait for the representative and beneficial books to read. Every book that is provided in better way and utterance will be expected by many peoples. Even ...

We provide algebraic semantics together with a sound and complete sequent calculus for information update due to epistemic actions. This semantics is flexible enough to accommodate incomplete as well as wrong information e.g. deceit. We give a purely algebraic treatment of the muddy children puzzle, which moreover extends to situations where the children are allowed to lie and cheat. Epistemic ...

Under reasonable assumptions, a group action on module extends to the minimal free resolutions of module. Explicit descriptions these actions can lead better understanding by providing, for example, convenient expressions their differentials or alternative characterizations Betti numbers. This article introduces an algorithm computing characters finite groups acting finitely generated graded mo...
