The research team is interested in modelling the entire energy chain, from production to consumption, including distribution and supervision. Understanding the precise physical functioning of production machines allows us to rationalise their use and use them for storage. An essential numerical part completes the work by proposing models of energy distribution networks and communication systems necessary for the optimisation of the whole.
Based on all engineering fields, innovative materials and structures are experiencing considerable growth. This involves the development of new technologies, including additive manufacturing and intelligent materials. The research team participates in this field of research by focusing on three subjects: multi-scale modelling of materials; improvement of additive manufacturing processes and characterisation of the performance of new materials.
Complex fluid modelling concerns all fluids that cannot be described by the Navier-Stokes equations. Most of the problems studied are related to complex fluid dynamics and multiphase flows, in particular fluid-particle interactions. The research developed involves interdisciplinary collaboration between several scientific fields. We propose a mathematical and numerical analysis of these fluids with industrial applications.

abstract = {The aim of this study was to quantify the tibio-femoral contact point (CP) locations in healthy and osteoarthritic (OA) subjects during a weight-bearing squat using stand-alone biplanar X-ray images. Ten healthy and 9 severe OA subjects performed quasi-static squats. Bi-planar X-ray images were recorded at 0°, 15°, 30°, 45°, and 70° of knee flexion. A reconstruction/registration process was used to create 3D models of tibia, fibula, and femur from bi-planar X-rays and to measure their positions at each posture. A weighted centroid of proximity algorithm was used to calculate the tibio-femoral CP locations. The accuracy of the reconstruction/registration process in measuring the quasi-static kinematics and the contact parameters was evaluated in a validation study. The quasi-static kinematics data revealed that in OA knees, adduction angles were greater (p<0.01), and the femur was located more medially relative to the tibia (p<0.01). Similarly, the average CP locations on the medial and lateral tibial plateaus of the OA patients were shifted (6.5±0.7?mm; p<0.01) and (9.6±3.1?mm; p<0.01) medially compared to the healthy group. From 0° to 70° flexion, CPs moved 8.1±5.3?mm and 8.9±5.3?mm posteriorly on the medial and lateral plateaus of healthy knees; while in OA joints CPs moved 10.1±8.4?mm and 3.6±2.8?mm posteriorly. The average minimum tibio-femoral bone-to-bone distances of the OA joints were lower in both compartments (p<0.01). The CPs in the OA joints were located more medially and displayed a higher ratio of medial to lateral posterior translations compared to healthy joints.},

The second one, called Shliomis model, is obtained by assuming that the angular momentum is given in terms of the magnetic field, the magnetization field and the vorticity. It consists of the incompressible Navier-Stokes equation, the magnetization equation and the magnetostatic equations. We prove, for each of the differential systems posed in a bounded domain of R3 and equipped with boundary conditions, existence of weak solutions by using regularization techniques, linearization and the Schauder fixed point theorem.},

abstract = {Pipelines are the very important energy transmission systems. Over time, pipelines can corrode. While corrosion could be detected by in-line inspection (ILI) tools, corrosion growth rate prediction in pipelines is usually done through corrosion rate models. For pipeline integrity management and planning selecting the proper corrosion ILI tool and also corrosion growth rate model is important and can lead to significant savings and safer pipe operation. In this paper common forms of pipeline corrosion, state of the art ILI tools, and also corrosion growth rate models are reviewed. The common forms of pipeline corrosion introduced in this paper are Uniform/General Corrosion, Pitting Corrosion, Cavitation and Erosion Corrosion, Stray Current Corrosion, Micro-Bacterial Influenced Corrosion (MIC). The ILI corrosion detection tools assessed in this study are Magnetic Flux Leakage (MFL), Circumferential MFL, Tri-axial MFL, and Ultrasonic Wall Measurement (UT). The corrosion growth rate models considered in this study are single-value corrosion rate model, linear corrosion growth rate model, non-linear corrosion growth rate model, Monte-Carlo method, Markov model, TD-GEVD, TI-GEVD model, Gamma Process, and BMWD model. Strengths and limitations of ILI detection tools, and also corrosion predictive models with some practical examples are discussed. This paper could be useful for those whom are supporting pipeline integrity management and planning.},

The technique is based on an extended homogenization scheme where the averaging operators are replaced by linear filters to cut off fine scale fluctuations, while maintaining locally varying mechanical fields with larger wavelength. As a result, the constitutive law at an intermediate scale, called mesoscale, arises to be naturally nonlocal by construction, where the kernel operator is fully constructed by computations on the unit cell associated with the microstructure.},

This problem is known also as concave minimization, concave programming or convex maximization. Such problems can have many local maxima, therefore finding the global maximum is a computationally difficult problem, since standard nonlinear programming procedures fail. In this article, we provide a very simple and practical approach to find the global solution of quadratic convex maximization problems over a polytope. A convex function achieves its global maximum at extreme points of the feasible domain. Since an inscribed ball does not contain any extreme points of the domain, we use the largest inscribed ball for an inner approximation while a minimal enclosing box is exploited for an outer approximation of the domain. The approach is based on the use of these approximations along with the standard local search algorithm and cutting plane techniques.},

abstract = {Purpose: Knee osteoarthritis (OA) is diagnosed and graded with a radiographic evaluation of the joint. However, there is no clear corre- lation between this grade and patient functional outcome scores (Sanghi et al. 2011; Zifchock et al. 2011, Alkan et al. 2013). This leads to the need of a quantitative and precise measure to represent the knee function. In the recent years, to evaluate healthy and OA knee function, the trend was to track skin markers displacements, known to be affected by soft tissue artefacts (Leardini et al., 2005). On the other hand, with imagery-based methods, 3D model acquired either from CT scan or Magnetic resonance imaging are matched on 2D fluoroscopic images (kinematics) or several radiographs (pseudo-kinematics) (Moro-Oka et al., 2006). With objects of known geometry in the radiographic scene (bone-embedded tantalum beads or prostheses), this matching allows attaining kinematic measurement accuracy <1 and <1mm. Without tantalum beads or prostheses, the process lacks reliability and accuracy. Thus, our goal is to present an intrinsic computation method - without any object added in the scene - and to validate its reliability on patients' images as well as its accuracy on simulated radiographs in a pseudo- kinematic context.},

Grains have variable volume fractions of pores, representing between 16 and 33%g water/g PVC, with pore sizes varying between 0.6 and 1?m. It is shown that the humid cakes exhibit three different drying rate regimes at constant temperature, characterizing evaporation of free water, of interstitial water and of water inside the pores. The constant rate period (CRP) and the falling rate period (FRP) of drying are clearly identified. The drying rates and drying times are presented in adimensional units by comparison with evaporation of pure water. The thermogravimetric analysis identifies a fraction of water which dries very slowly inside the pores. A method of quantifying the strongly bound water is presented. Numerical simulations of water evaporation were performed on a 2D array of channels and illustrate the contribution of geometrical effects (diameter of channels, tortuosity, etc.) in pore drying. Visual observations of the drying of droplets of solutions containing dispersants used in PVC synthesis show interesting patterns. The phase separated solutions of dispersants are analyzed and their role in drying is highlighted.},

abstract = {Concentration of aqueous suspensions of solid particles (called slurries in industrial processes) is achieved by centrifugation at high accelerations and it is an important step in dry powder productions; dehydration precedes drying. In aqueous suspensions of porous particles, water is both the interstitial fluid, which disperses the particles and the imbibition fluid, which fills the pores inside particles. This is the case in the pastes of poly(vinyl)chloride (PVC) polymerized in suspensions after centrifugation. PVC grains are non-colloidal particles with diameters close to 150?m and variable inner porosity, which are synthetized in aqueous solutions using dispersants such as various poly(vinyl)alcohols (PVA). In this paper we determine the dehydration by centrifugation of different grades PVC suspensions with laboratory scale experiments. It is shown that the humid pastes reach a pendular state at high accelerations and that the compaction of the grains and their surface properties determine the final retention of the water by capillary forces. In such conditions, internal water, inside the pores of the grains can be eliminated only by evaporation. Drying was investigated in controlled relative humidity atmospheres (RH) in desiccators by measuring the equilibrium moisture content of the grains and the evaporation rates. The evaporation rate of the superficial water is similar to pure water and can be interpreted using Stefan's equation, whereas substantial differences exist between the total drying times of grades.},

By gradually changing the actual power grid system, smart grid may evolve into different systems by means of size, elements and strategies, but its fundamental requirements and objectives will not change such as optimizing production, transmission, and consumption. Studying the smart grid through modeling and simulation provides us with valuable results which cannot be obtained in real world due to time and cost related constraints. Moreover, due to the complexity of the smart grid, achieving global optimization is not an easy task. In this paper, we propose a complex system based approach to the smart grid modeling, accentuating on the optimization by combining game theoretical and classical methods in different levels.

We show that even though the predicted temperature is advected by a velocity prediction which is not necessarily divergence free, the theoretical time accuracy of the global scheme is conserved. From a numerical point of view, this new approach gives a faster and more efficient algorithm compared to the usual fixed-point approaches.},

abstract = {To investigate clinical questions as kinematic or postural differences between healthy and pathological populations,the current trend is to couple imagery to movement or to posture. To do so, researchers generally register a three-dimensional (3D) model acquired from either CT scan or magnetic resonance imaging on 2D fluoroscopic images(registration on dynamic activities) or several radiographs (registration on posture or pseudo-kinematics) (Moro-oka et al.2007). The literature suggests the use of so-called?extrinsic 2D/3D registration'. This implies the need of geometrical objects in the radiographic scene. Embedded tantalum beads or prostheses (Scarvell et al.2010; Sharmaet al.2012), well detectable on the radiographs, are generally used. They allow attaining the expected measurement accuracy <1° and <1mm. When no tantalum beads or prostheses are present, the registration process lacks reliability and accuracy because of the difficulty to extract precise information from the radiographic images (blurry contours, superimposition of structures and cylindrical nature of long bones) (Belvedere et al.2013). The goal of this work was to present an intrinsic 2D/3D registration method and to validate its reliability on patients' images as well as its accuracy on simulated radiographs in a pseudo-kinematic context.},
