Tribological behavior of composites fabricated by reactive SPS sintering in Ti‐Si‐C system

Youcef Hadji, Abdessabour Benamor, Nabil Chiker, Adel Haddad, Nacer Tala-Ighil, Jean-Pierre Erauw, Vedi Dupont, Arnaud Tricoteaux, Christelle Nivot, Anthony Thuault, Mohamed Hadji

In this study, wear and friction behavior of two based-composites from the Ti-Si-C system, (40 wt% TiC; 28 wt% Ti5Si3; 17 wt% Ti3SiC2) and (18 wt% TiC; 26 wt% Ti5Si3; 41 wt% Ti3SiC2) reinforced by 15 wt% of large size SiC (100-150 µm) particles were investigated. The four-phase composites exhibited...

Performance and Crosstalk Evaluation of 2-D Array Piezoelectric Micromachined Ultrasonic Transducer with 3-D Finite Element Simulation

Le-Ming He, Wei-Jiang Xu, Wen-Juan Liu, Xu-Bo Wang, Jia Zhou, Jun-Yan Ren

Micro-machined ultrasonic transducer (MUT) arrays have their structure and fabrication technology fundamentally different to those of thickness mode piezoelectric transducers. Their performance needs to be modelled and optimized before MEMS fabrication process is engaged. A 3-dimentional finite...

A Modified Hybrid Variable Neighborhood Search for the Truck Scheduling Problem on a Multiple-door Cross-docking Terminal

Tarik Chargui, Abdelghani Bekrar, Mohamed Reghioui, Damien Trentesaux

In the logistics context, many optimization problems can be found and they concern the global supply chain optimization which takes into account the whole logistics networks with all its elements: suppliers, distribution centers and retailers on the one hand, and the optimization of the scheduling...

Daily Scheduling and Routing of Home Health Care with Multiple Availability Periods of Patients

Mohammed Bazirha, Abdeslam Kadrani, Rachid Benmansour

The home health care routing and scheduling problem (HHCRSP) is an extension of the vehicle routing problem with time windows (VRPTW). It consists of providing services operations at patients’ homes in case of aging or disabling disease. In this paper, we address the HHCRSP with multiple...

Optimization of Maintenance Planning and Routing Problems

Lamiaa Dahite, Abdeslam Kadrani, Rachid Benmansour, Rym Nesrine Guibadj, Cyril Fonlupt

This paper addresses a problem that maintenance service providers often face: determining the best routing-maintenance policy for all technicians and machines. It consists of defining for each technician the sequence of the maintenance operations to perform so that the total expected costs are...

Asynchronous bi-local search based variable neighborhood search for Job-shop scheduling problem with transport constraints

Moussa Abderrahim, Abdelghani Bekrar, Damien Trentesaux, Nassima Aissani, Karim Bouamrane

In job-shop manufacturing systems, an efficient production schedule acts to reduce unnecessary costs and better manage resources. For the same purposes, modern manufacturing cells, in compliance with industry 4.0 concepts, use material handling systems in order to allow more control on the...

Les modèles socio-économiques associatifs. Revue de littérature

Elisabetta Bucolo, Philippe Eynaud, Laurent Gardin

Les modèles socio-économiques des associations font l’objet de débats importants en raison de la crise économique, du recul de l’État providence et de la montée du libéralisme. Cette revue de littérature retrace ces débats sans en ignorer les limites. En effet, les controverses s’enferment...

Less is more: general variable neighborhood search for the capacitated modular hub location problem

Marija Mikić, Raca Todosijević, Dragan Urošević

In this paper, we study the capacitated modular hub location problem. The problem belongs to the class of the single assignment hub location problems, where a terminal can be assigned to only one hub. In addition, the problem imposes capacity constraints, on both hubs and edges that connect them....

Hierarchical Collborative Platform for Autonomous Driving.

Hamza Ouarnoughi, Mohamed Ayoub Neggaz, Berkay Gulcan, Özcan Özturk, Smail Niar

Autonomous driving (AD) comes with inherent chal-lenges. Speciﬁcally, many of the actions taken by the autonomousvehicle are based on increasingly complex algorithms, mainlyapplied from the artiﬁcial intelligence (AI) domain such as deepneural networks (DNN). These algorithms are known for...

Hybrid color MRI image compression by level set method and quincunx wavelet

Imane Haouam, Mohammed Beladgham, Abdelmalik Taleb-Ahmed

In recent years, researchers have increasinglytargeted the development of hybrid systems to improve thequality of the compressed image. Hybrid methods arecombinations of several techniques that take into account theadvantages and disadvantages of it, in order to obtain a betterimage quality with a...
