Nested backward compensation of unmatched perturbations via HOSM observation

Alejandra Ferreira de Loza, E. Punta, Leonid Fridman, Georgio Bartolini, Sebastien Delprat

This paper tackles the compensation problem of linear time invariant systems affected by unmatched perturbations. The proposed methodology exploits a high order sliding mode observer, guaranteeing theoretically exact state and perturbation estimation. A compensation based strategy is proposed to...

Evaluation tools through user participation techniques: Features, limitations, and new perspectives

Selem Charfi, Houcine Ezzedine

The evaluation of user interfaces is a rich theme in terms of concepts, approaches, and tools. The related tools are numerous that they are mainly classified into two categories. The first one includes the tools based on expert analysis techniques. These tools require a designer and/or an evaluator...

Heat transfer of Cu–water nanofluid in an enclosure with a heat sink and discrete heat source

Hamdy Hassan

Heat transfer inside horizontal and vertical enclosure filled with Cu-water nanofluid is studied. A heat sink with rectangular fins represents the base plate of the enclosure where it is heated by a discrete heat source at the bottom of the heat sink. The front face of the heat sink is kept at...

Identification of Friction Law to Model Orthogonal Cutting

Yannick Senecaut, Michel Watremez, Julien Brocail, Laurent Dubar

A first approach of tool-chip interface behaviour for high-speed machining modelling has been carried out by Al Brocail and 2010 and an empirical friction law has been first determined. This law has been established for high temperatures (initial sample temperature equal to 750 K) and low sliding...

Balance control in gait children with cerebral palsy

Laura Wallard, Gilles Dietrich, Yves Kerlirzin, Jonathan Bredin

This study sought to highlight the balance control process during gait in children with cerebral palsy (CP) by analyzing the different strategies used in order to generate forward motion while maintaining balance. Data were collected using a motion analysis system in order to provide a clinical...

Heuristic approch for solving the makespan problem in a hospital sterilization service

Amal Soufi, Anis Mjirda, Mourad Abed

In this work, we focus on the study of a scheduling problem that arises in the sterilization services in hospitals. The main role of a sterilization service is the disinfection of the reusable medical devices used in surgical operation rooms. Sterilization process has a well-defined cycle and it...

Scheduling under uncertainty: Survey and research directions

Tarek Chaari, Sondès Chaabane, Nassima Aissani, Damien Trentesaux

In real-world scheduling problems, several kinds of hard-to-predict risk must be considered. Scheduling under uncertainty allows these kinds of risks to be taken into account. This paper provides an overview of the state of the art in scheduling under uncertainty, including a survey on modeling...

The cross docking under uncertainty: State of the art

Faiza Walha, Sondès Chaabane, Abdelghani Bekrar, Taicir Loukil

Cross docking is defined as a consolidation process which integrates intermediate nodes into a transportation network where the goal is to reduce the inventory holding and the service time. This paper presents a review of the existing literature about the cross-docking under uncertainty. The...
