Integrated quay crane and yard truck scheduling problem at port of Tripoli-Lebanon
The scheduling problem is one of the most important operation in maritime ports. In this study we solved the scheduling problem for a single quay crane and multiple yard trucks in port of Tripoli-Lebanon. In a previous study we proposed two exact methods for this problem but we faced a problem for large instances in […]

X-ray photoabsorption-induced processes within protonated rifamycin sodium salts in the gas phase
Up to now, the response of antibiotics upon ionizing radiation has been very scarcely reported. Here, we present the results of X-ray photoabsorption experiments on isolated rifamycin, a broad-range antibiotic against Gram-positive and Gram-negative bacteria. A mass spectrometer has been coupled to a synchrotron beamline to analyze cationic products of photoabsorption on protonated rifamycin dimer […]

La didactique professionnelle pour relier travail et formation
Alors qu’aujourd’hui les situations de travail deviennent des objets pour la formation, la didactique professionnelle se présente comme un cadre théorique et une approche méthodologique qui assurent une performance aux activités de transmission et développement de compétences. Quatre articles majeurs sur le lien Travail et Formation y sont présentés, ils couvrent une large période de […]

use case study comparing augmented reality (AR) and electronic document-basedmaintenance instructions considering tasks complexity and operator competency level
Augmented reality (AR) is more and more used in the industrial context for maintenance, assembly operation. However, owing to the evolution and maturity of the technology, it is still necessary to evaluate the usage and benefits of AR in an industrial context to go further than proof of concept. As such, this paper proposes an […]

RPL-OC: Extension of RPL Protocol for LLN Networks based on the Operator Calculus approach
Technical constraints imposed by low-power and lossy networks (LLNs) require to defer complexity to routing protocols in order to efficiently and reliably transmit packets. However, despite these constraints, the deployment of this type of network has increased considerably over the last years, particularly in smart cities area with focus on sensing applications. In order to […]

Multi-agent modeling and simulation of wind turbine behavior with failure propagation consideration
Simulation is an interesting technique to represent and predict the behavior of complex system such as wind turbines. In order to get accurate representation of the real turbines, the main factors influencing the operating state of the system must be considered during the development of the model. Stochastic dependencies between components are among the factors […]

MODULAR AND TRANSPORTABLE MANUFACTURING UNIT PROVIDING A HIGH LEVEL OF INDUSTRIAL SECURITY, PARTICULARLY FOR ADDITIVE METAL MANUFACTURING
The unit (1) comprises a plurality of modules (M1 to M4) which are constructed from transport containers. The modules are assembled in a removable manner and have, between two juxtaposed modules, at least one spatial communication zone which comprises opposite openings and joining and sealing means. The unit comprises a confined zone (ZC) which accommodates […]

Adherence of geopolymer and pultruded composite substrates: influence of adhesive type and surface treatment
In the last years, the use of adhesive bonding is increasing as an alternative to traditional joining techniques due to their advantages such as ease of application, low weight and the good mechanical properties. To ensure good adherence between the substrates, adequate materials and surface treatment are required. The main objective of this work is […]

Fiber-matrix bond strength by pull-out tests on slag-based geopolymer with embedded glass and carbon fibers
The reinforcement efficiency on a composite depends on the effective transfer of the stress between matrix and fiber. This work presents an experimental and comparative study of fibermatrix bond strength for fiber-matrix interface between glass fibers and carbon fibers added to the slag-based geopolymer matrix. This analysis was performed by pull-out test. A total of […]

Effect of Scalping on the Mechanical Behavior of Coarse Soils
This paper aims at presenting a study of the effect of scalping methods on the mechanical properties of coarse soils by resorting to numerical simulations based on the discrete element method (DEM) and experimental triaxial tests. Two reconstitution methods are used, designated as scalping method and substitution method. Triaxial compression tests are first simulated on […]

Reliability-driven Automotive Software Deployment based on a Parametrizable Probabilistic Model Checking
several interacting nodes. Designing such systems includes hardware parts and software parts. The software part acquires in importance since it handles the resources and services to interact with the hardware part. The paper introduces a novel deployment-decision making based on PRISM probabilistic model checker that takes software components and the physical platform to produce a […]
