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 […]

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 […]

Mixed-integer linear programming models for the simultaneous unloading and loading processes in a maritime port
This paper discusses the jointly quay crane and yard truck scheduling problems (QCYTSP) with unloading and loading containers from/to vessel(s) in the same time. Yard trucks transport the containers to/from yard locations with all containers that are homogeneous.We propose a mixed integer linear programming model to solve the scheduling problem. We consider in this study, […]

A model-free reinforcement learning approach for the energetic control of a building with non-stationary user behaviour
We consider a system providing a service to a user (smart building, vehicle…) and allowing the user to interact with it. The service provided to the user regulates physical signals of the user’s surroundings (lighting, heating, radio sound,…). The user can interfere with the system to affect the values of those signals to adjust the […]

Multi-component modeling and classification for failure propagation of an offshore wind turbine
Purpose Improving reliability is a key factor in reducing the cost of wind energy, which is strongly influenced by the cost of maintenance operations. In this context, this paper aims to propose a degradation model that describes the phenomenon of fault propagation to apply proactive maintenance that will act on the cause of failure to […]

InHARD – Industrial Human Action Recognition Dataset in the Context of Industrial Collaborative Robotics
Nowadays, humans and robots are working more closely together. This increases business productivity and product quality, leading to efficiency and growth. However, human and robot collaboration is rather static; robots move to a specific position then humans perform their tasks while being assisted by the robots. In order to get a dynamic collaboration, robots need […]

Modeling Attack-Defense Trees’ Countermeasures using Continuous Time Markov Chains
ADTrees (Attack-Defense Trees) are graphical security mod- eling tools used to logically represent attack scenarios along with their corresponding countermeasures in a user-friendly way. Many researchers nowadays use ADTrees to represent attack scenarios and perform quan- titative as well as qualitative security assessment. Among all di erent existing quantitative security assessment techniques, CTMCs (Continu- ous […]

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 […]

A New Dataset of People Flow in an Industrial Site with UWB and Motion Capture Systems
Improving performance and safety conditions in industrial sites remains a key objective for most companies. Currently, the main goal is to be able to dynamically locate both people and goods on the site. Security and access regulation to restricted areas are often ensured by doors or badge barriers and those have several issues when faced […]

Towards the specification of an integrated measurement model for evaluating VR cybersickness in real time
Cybersickness (CS) is an affliction that limits the use of virtual reality (VR) applications. For decades, the measurement of cybersickness has presented one of the most challenges that have aroused the interest of VR research community. Having strong effects on users’ health, cybersickness causes several symptoms relating to different factors. In most cases, the literature […]

User behaviour-based approach to define mobility devices needs of disabled person in Algeria: a questionnaire study
Purpose: This article showcases the adaptability of existing mobility devices for the Algerian disabled population. It aims to develop a behavior model of disabled Algerian persons through (1) development of a theoretical model based on literature review and (2) improvement of this model by using local collected data from our developed questionnaire. Methods: The majority […]
