The present contribution provides an overview of various issues susceptible to arise in the international management of intellectual property right. Chapter I deals with patents and describes, on the one hand, a variety of legal options (novelty, exhaustivity, mandatory licensing, ...) that States can take to influence the management of patent portfolios abroad and, on the other hand, the forum shopping strategies that multinationals may implement to take advantage from the rules that favor them most. Chapter II deals with traditional knowledge issues and lists the various methods of protection – whether defensive or offensive – that States may implement to prevent free exploitation of traditional knowledge abroad. Sui generis regimes, trade secrecy, unjust enrichment and extra contractual liability are discussed. Various examples are given. [less ▲]

Control charts are the primary tools of statistical process control. These charts may be designed by using a simple rule suggested by Shewhart, by a statistical criterion, an economic criterion or a joint economic-statistical criterion. Each method has its strengths and weaknesses. One weakness of the methods of design listed above is their lack of flexibility and adaptability, a primary objective of practical mathematical models. In this paper, we explore multi objective models as an alternative for the methods listed above. These provide a set of optimal solutions rather than a single optimal solution and thus allow the user to tailor their solution to the temporal imperative of a specific industrial situation. We present a solution to a well known industrial problem and compare optimal multi objective designs to economic designs, statistical designs, economic statistical designs and heuristic designs.

STARESO (Station de REcherche Sous marine et Océanographique) is the marine and oceanographic research station of the University of Liège (Belgium) managed by the French company STARESO S.A.. Constructed in 1969, it is located near Calvi (Corsica, Western Mediterranean Sea) in an oligotrophic area chosen for the exceptional quality of its coastal waters STARESO offers to the oceanographers, by diving or with boats, a direct access to the sea. The variety of the accessible ecosystems is remarkable and unique in the Mediterranean basin: -the Bay of Calvi is characterized by healthy and very diverse biocenosis (e.g. Posidonia meadows, rocky and sandy communities, -a steep submarine canyon, with depths greater than 1 000 meters, is accessible in 15 minutes of navigation; -the Liguro-Provençal front, a major hydrologic structure, is situated between 10 and 15 miles of the coast. STARESO is accessible all the year for everybody and is functioning like an oceanographic research vessel. The Station is a platform for all oceanographic disciplines with a scientific expertise widely based on a long tradition of interdisciplinary work, and a direct access to time series of physical, chemical and biological data registered with automated systems and variety of sensors deployed in the Bay of Calvi since 30 years. This platform provides the opportunity to reach coastal, pelagic, benthic, deep systems with a manageable cost and ship requirements in a pristine zone. [less ▲]

We formulate an entanglement criterion using Peres-Horodecki positive partial transpose operations combined with the Schrödinger-Robertson uncertainty relation. We show that any pure entangled bipartite and tripartite state can be detected by experimentally measuring mean values and variances of specific observables. Those observables must satisfy a specific condition in order to be used, and we show their general form in the 2 x 2 (two qubits) dimension case. The criterion is applied on a variety of physical systems including bipartite and multipartite mixed states and reveals itself to be stronger than the Bell inequalities and other criteria. The criterion also work on continuous variable cat states and angular momentum states of the radiation field. [less ▲]

We show that a positive homogeneous function that is invariant under determinant 1 stochastic local operations and classical communication (SLOCC) transformations defines an N-qubit entanglement monotone if and only if the homogeneous degree is not larger than four. We then describe a common basis and formalism for the N-tangle and other known invariant polynomials of degree four. This allows us to elucidate the relation of the four-qubit invariants defined by Luque and Thibon [Phys. Rev. A 67, 042303 (2003)] and the reduced two-qubit density matrices of the states under consideration, thus giving a physical interpretation for those invariants. We demonstrate that this is a special case of a completely general law that holds for any multipartite system with bipartitions of equal dimension, e.g., for an even number of qudits. [less ▲]

Production scheduling and vehicle routing problems are well-known topics in operations management. Although these tasks are consecutive in the supply chain, few optimization models tackle the associated issues. A most common situation, in practice, is actually that transportation management is disconnected from production planning: when production items or batches have been completely processed by the manufacturing plant, they become available for shipping, and they are consequently handled by the transportation managers. From a global managerial perspective, and with a view towards coordination of the product flows and customer satisfaction, this is not an ideal process. It is by far preferable, indeed, to set up an integrated production-transportation plan taking into account, among other constraints, the capacity of the plants and the customer due-dates. The present research proposes a methodology to investigate a multi-period vehicle loading problem with deterministic or stochastic information concerning items arrivals from production. Results from related optimization techniques are statistically compared and the benefits of the multi-period and stochastic modeling is demonstrated. Finally, an efficient heuristic is highlighted and is shown to be robust to the deviation from item arrival forecasts. [less ▲]

For over 15 years, our research group at the University of Liege has been conducting basic and applied research on flow and transport phenomena involved in environmental and civil engineering applications. The research topics cover a wide range of multiphase flow, including aerated flow and sediment-laden flow. The research group has developed the modelling system WOLF, which performs 1D, 2D-horizontal, 2D-vertical and 3D simulations of free surface and pressurized flow, coupled with air- or sediment-transport as well as morphodynamic simulations [9]. An original depth-averaged k- model is used to evaluate the eddy viscosity and diffusivity [5]. In a composite modelling approach [e.g., 2, 8], the numerical simulations have systematically been carried out in parallel with experimental research in flumes and scale models of hydraulic structures [3, 4, 7]. A particularly challenging issue in multiphase flow modelling is the need to handle accurately and efficiently a wide range of time scales involved in the relevant phenomena (e.g., sediment transport). Therefore, the modelling system provides a series of complementary numerical schemes designed to be combined for covering the whole range of relevant time scales. This presentation will provide examples of analysis of aerated flow, such as on stepped spillways and in penstocks [6], and of reservoir sedimentation. In particular, recent experimental findings have revealed that the flow pattern in rectangular shallow reservoirs is considerably modified at a macro-scale when suspended load is added to the flow [1]. This sudden change in flow pattern has been observed to take place quickly after the beginning of the experiment, so that it is very unlikely to result from morphodynamic changes of the reservoir bottom. Therefore, the numerical model WOLF has been used to investigate the effect of two other possible feedback mechanisms of sediment deposits and suspended load on the overall flow pattern, namely (i) increased bottom roughness and (ii) turbulence damping. From the simulations results, it can be argued that turbulence intensity is probably the main cause for the flow pattern to change at a macro-scale, as suspended load exerts a turbulence damping effect at a micro-scale in the two-phase flow (water-sediment mixture). Finally, the analysis of flow and sediment transport in shallow rectangular reservoirs also highlights the need, when structures are designed based on numerical simulations, to carefully check the stability of the computed flow fields needs by conducting sensitivity analyses, not only with respect to the modelling parameters but also with respect to the initial conditions.

In this paper, the multiphase time dependent compression behaviour of two chalks are considered within a fully coupled general hydro-mechanical framework derived from the mechanics of unsaturated soil. In the former case, reservoir chalks contain oil and water and subsidence appeared once enhanced oil recovery by waterflooding started. In the latter case, water saturated chalk is periodically desaturated by water evaporation, resulting in air penetration. In this paper, the fluid retention curves of both samples are determined and the data obtained are used in the interpretation of suction controlled compression tests where time effects appear to be significant. The experimental data obtained show the relevance of the approach adopted. [less ▲]

Electrostatic actuation is often used in microsystems as it is relatively easy to implement and provides a short response time. However, because of the non-linearity of electrostatic forces, these devices may suffer from an unstable behavior called pull-in effect. Previous work of the authors intended to delay pull-in effect by maximizing pull-in voltage studying a simplified problem where the optimization domain was purely mechanical. The present paper generalizes the approach by considering a multiphysic optimization domain. However, the generalization of the optimization problem is not straightforward as local pull-in modes appear after a few optimization iterations. Therefore, the paper investigates several solutions to prevent the appearance of local pull-in modes. [less ▲]
