The apparition of Fuzzy Logic [10] has had a double repercussion on scientific research, and has provoked two types of reactions. From a theoretical point of view, it is indeed a very useful generalization of the classical Set Theory proposed by Boole and Cantor, in this way making possible our analysis of uncertainty. But unfortunately, in his first steps it had to avoid the assaults of routin...

The security of critical infrastructures is decreasing due to the apparition of new cyber threats against Supervisory Control and Data Acquisition (SCADA) systems. The evolution they have experienced; the use of standard hardware and software components or the increase of interconnected devices in order to reduce costs and improve efficiency, have contributed to this. This work reviews the rese...

We deene a general methodology to deal with a large family of scheduling problems. We consider the case when some of the constraints are expressed through the minimization of a loss function. We study with more details a benchmark example consisting in some jigsaw puzzle problem with additional constraints. This is the occasion to discuss some algorithmic issues typical of scheduling problems, ...

The RNA world hypothesis refers to the early period on earth in which RNA was central in assuring both genetic continuity and catalysis. The end of this era coincided with the development of the genetic code and protein synthesis, symbolized by the apparition of the first non-random messenger RNA (mRNA). Modern transfer-messenger RNA (tmRNA) is a unique hybrid molecule which has the properties ...

The main goal of this paper is to present a user interface for a multi-agent system “MACIV” [1]. The aim of the MACIV project is the design and implementation of a computer system, mainly based on Distributed Artificial Intelligence techniques, enabling a decentralised management of different resources in Civil Construction Companies. The user interface is implemented using the Tcl and Tk packa...

The dielectric properties of elastin were investigated at different levels of hydration and specifically at the limit of freezable water apparition. The quantification of freezable water was performed by Differential Scanning Calorimetry (DSC). Two dielectric techniques were used to explore the dipolar relaxations of hydrated elastin: dynamic dielectric spectroscopy (DDS), performed isothermall...

We benchmark in this article three different parametrizations for punctual landmarks in monocular 6DOF EKF-SLAM. These parametrizations are homogeneous points (HM), inverse-distance points (IDP, better known as inversedepth), and the new anchored homogeneous points (AHP). The discourse used for describing them is chosen to highlight their differences and similarities, showing that they are just...

We consider a circular arch of thickness ε and curvature r−1 whose elastic deformations are described by a 2×2 system of linear partial differential equation. The system of the type y′′ + Ay = 0,y = (y1, y3) involves the tangential y1 and normal y3 component of the arch displacement. We analyze in this work the null controllability of these two components by acting on the boundary through a Dir...

When it is polarised, a cell develops an asymmetric distribution of specific molecular markers, cytoskeleton and cell membrane shape. Polarisation can occur spontaneously or be triggered by external signals, like gradients of signalling molecules... In this work, we use the models of cell polarisation introduced in [9] and [4] and we set a numerical analysis for these models. They are based on ...

Along with a continuously growing number of publicly available Web services (WS), we are witnessing a rapid development in semantic-related web technologies, which lead to the apparition of semantically described WS. In this work, we perform a comparative analysis of the syntactic and semantic approaches used to describe WS, from a complex network perspective. First, we extract syntactic and se...
