Fluid flow and convective heat transfer analysis on a rotor of wind turbine alternator with an impinging jet

Chadia Haidar, Rachid Boutarfa, Souad Harmand

This work presents a numerical and experimental study of convection heat transfer in the unconfined air gap of a discoidal technology rotor-stator system. In particular, the rotor is cooled here by an eccentric air jet impingement. The cavity is characterized by a dimensionless spacing G = 0.02 and…

Local wall temperature mapping during flow boiling in a transparent microchannel

Sofia Korniliou, Coinneach Mackenzie-Dover, Souad Harmand, Gail Duursma, John R.E. Christy, J.G. Terry, A.J. Walton, K. Sefiane

In this study the local two-phase heat transfer coefficients were obtained using wall temperature measurements and fluid saturation temperatures in a rectangular high-aspect-ratio polydimethylsiloxane (PDMS) microchannel with a hydraulic diameter of 192 μm. The experiments used FC-72 liquid with a…

An alternative LMI static output feedback control design for nonlinear systems represented by Takagi-Sugeno models

Víctor Estrada Manzo, Zsofia Lendek, Thierry-Marie Guerra

This paper presents a static output feedback controller design for discrete-time nonlinear systems exactly represented by Takagi–Sugeno models. By introducing past states in the control law as well as in the Lyapunov function, more relaxed results are obtained. Different conditions in terms of…

On the Local Stabilization of Hybrid Limit Cycles in Switched Affine Systems

Mohammed Benmiloud, A. Benalia, Mohamed Djemai, Michael Defoort

Most of the proposed controllers for switched affine systems are able to drive the system trajectory to a sufficiently small neighborhood of a desired state. However, the trajectory behavior in this neighborhood is not generally considered despite the fact that the system performance may be judged…

Anticipatory postural adjustment during gait initiation in multiple sclerosis patients: A systematic review

Caroline Massot, Emilie Simoneau-Buessinger, Olivier Agnani, Cécile Donzé, Sébastien Leteneur

Background: Multiple sclerosis (MS) causes balance and walking disorders. Gait initiation is the complex transition between standing and walking and is characterized by two distinct phases: the anticipatory postural adjustment (APA) phase followed by the execution of the first step phase. Research…

Défis de l’automatisation des systèmes sociotechniques

Frédéric Vanderhaegen, Choubeila Maaoui, Mohamed Sallak, Denis Berdjag

Les défis de l’automatisation des systèmes sociotechniques sont fortement liés à la prise en compte des atouts et des limites des ressources techniques et humaines, tels que les caractéristiques perceptives, les capacités coopératives, les modalités de partage de tâches, la modélisation de…

Multi-Objective Sustainable Truck Scheduling in a Rail–Road Physical Internet Cross-Docking Hub Considering Energy Consumption

Tarik Chargui, Abdelghani Bekrar, Mohamed Reghioui, Damien Trentesaux

In the context of supply chain sustainability, Physical Internet (PI or π ) was presented as an innovative concept to create a global sustainable logistics system. One of the main components of the Physical Internet paradigm consists in encapsulating products in modular and standardized PI-…

Personalised lane keeping assist strategy: adaptation to driving style

Jagat Jyoti Rath, Chouki Sentouh, Jean-Christophe Popieul

The research in advanced driver assistance systems (ADAS) has progressed to design architectures for driver specific performance. Personalised ADASs in this aspect have been developed with adaptation to driver attributes, state, style, behaviour, skill and so on. For the lane keeping task, the…

De l'optimisation des opérations à l’alignement stratégique

Said Hanafi, Michel Labour, Igor Crevits

L’alignement stratégique repose sur les deux phases d’adaptation de la stratégie et d’intégration fonctionnelle au sein de l’organisation qui présentent une dimension décisionnelle importante. Les technologies de l’information offrent un pouvoir structurant à l’organisation mais également de…, Strategic alignment relies on both adaption of strategy and functional integration inside the organisation which refer to decisions. Information technologies allow improving the structure of the organisation and offer new opportunities which can extend to the market outside the organisation.…

Propagation of singularities in shells of non-uniform geometrical nature. A numerical investigation

Fabien Béchet

This paper deals with the propagation of singularities in thin elastic shells whose middle surface is not of an uniform nature. Numerical computations are performed using an adaptive mesh procedure proposed by the software Abaqus to refine the mesh inside the internal layers. The computation are…
