The e-commerce is a good research area because it is well fit ted the application of agents that interact each other with autonomy in dynamic environment. The ability of learning is one important point as intelligent agent supporting autonomy. In this research we develop learning algorithm suited e-commerce characteristic. We classify agents by learning level and delegate agent business with th...

Several formalisms for implementing organizational policies that assign specij2 roles to agents in a MAS have been proposed like the contract net protocol (CNP), the social reasoning mechanism (SRIM), and the distributed computational economy (DCE). Organization self design (OSD) had been proposed to achieve load balancing in a distributed environment. In this paper we propose an adaptive organ...

The rules for inheritance of classes with respect to data and function members are well defined. For example, the proposals for programming by contract in Eiffel ensure additional consistency between superclasses and subclasses. In object-oriented design, it is common to capture the behaviour of classes with lifecycles which are expressed in the form of finite state machines. In this context, t...

In this paper we deal with the Critical Node Problem (CNP), i.e., the problem of searching for a given number K of nodes in a graph G, whose removal minimizes the (weighted or unweighted) number of connections between pairs of nodes in the residual graph. In particular, we study the case where the physical network represented by graph G has a hierarchical organization, so that G is a tree. The ...

,"The C-type natriuretic peptide induces thermal hyperalgesia through a noncanonical Gβγ-dependent modulation of TRPV1 channel. cascade recruited by CNP in mouse DRG neurons that can lead to enhanced nociceptor excitability and thermal hypersensitivity.

Aiming at combining the good characteristics of a differential scale in representing human cognition and the favorable properties of interval judgments in expressing decision-makers’ uncertainty, this paper proposes the interval cognitive network process (I-CNP) to extend the primitive cognition network process (P-CNP) to handle interval judgments. The key points of I-CNP include a consistency ...

The deployment of multi-agent systems demands for justified confidence into their behaviour, both with respect to correct results of computations and with respect to timeliness thereof. Depending on the stage of the development process different mechanisms and abstractions are needed to facilitate the rigorous evaluation of interacting agents. We propose a modelling and simulation framework for...

This work deals with Workflow Mining (WM) a very active and promising research area. First, in this paper we give a critical and comparative study of three representative WM systems of this area: the ProM, InWolve and WorkflowMiner systems. The comparison is made according to quality criteria that we have defined such as the capacity to filter and convert a Workflow log, the capacity to discove...

We present a new Immune Algorithm, IMMALG, that incorporates a Stochastic Aging operator and a simple local search procedure to improve the overall performances in tackling the chromatic number problem (CNP) instances. We characterize the algorithm and set its parameters in terms of Kullback Entropy. Experiments will show that the IA we propose is very competitive with the state-of-art evolutio...

This article addresses the differentiated impacts of various sectors and branches in a multi-layer regional system. As a case-study the Cairngorms National Park (CNP) in Scotland is used. In this area, policy makers —at different administrative levels— strongly emphasize the need for new sustainable economic development. We use a novel combination of stakeholder analysis with household question...
