Ant colony optimisation combined with variable neighbourhood search for scheduling preventive railway maintenance activities

Safa Khalouli, Rachid Benmansour, Said Hanafi

Railway infrastructure maintenance is of fundamental importance in order to ensure a good service in terms of punctuality, safety and efficiently operation of trains on railway track and also for passenger comfort. Track maintenance covers a large amount of different activities such as inspections…

Investigation of Optimal Afferent Feedback Modality for Inducing Neural Plasticity with A Self-Paced Brain-Computer Interface

Mads Jochumsen, Sylvain Cremoux, Lucien Robinault, Jimmy Lauber, Juan Carlos Arceo Luzanilla, Muhammad Navid, Rasmus Nedergaard, Usman Rashid, Heidi Haavik, Imran Khan Niazi

Brain-computer interfaces (BCIs) can be used to induce neural plasticity in the human nervous system by pairing motor cortical activity with relevant afferent feedback, which can be used in neurorehabilitation. The aim of this study was to identify the optimal type or combination of afferent…

A simple multi-wave algorithm for the uncapacitated facility location problem

Fred Glover, Said Hanafi, Oualid Guemri, Igor Crevits

The multi-wave algorithm (Glover, 2016) integrates tabu search and strategic oscillation utilizing repeated waves (nested iterations) of constructive search or neighborhood search. We propose a simple multi-wave algorithm for solving the Uncapacitated Facility Location Problem (UFLP) to minimize…

Physical Performance Variables and Bone Mineral Density in a Group of Young Overweight and Obese Men

César El Khoury, Antonio Pinti, Eric Lespessailles, Ghassan Maalouf, Eric Watelain, Georges El Khoury, Abdel Jalil Berro, Marie-Louise Ayoub, Hechmi Toumi, Rawad El Hage

The aim of this study was to explore the relationships between performances obtained in different physical tests and bone parameters (bone mineral density [BMD], bone mineral content, hip geometry indices, and trabecular bone score [TBS]) in a group of young Lebanese overweight and obese adult men…

Timetable rearrangement to cope with railway maintenance activities

Luis Diego Arenas Pimentel, Paola Pellegrini, Said Hanafi, Joaquin Rodriguez

Maintenance activities on the railway infrastructure are necessary to maintain its functionality and availability. Commonly, the maintenance activities are planned first. Then, the timetable is elaborated respecting the unavailability periods caused by the former. However, sometimes unplanned…

Healthcare decision support tool: multi-agent system for bed management

Nesrine Zoghlami, Besma Glaa, Souad Rabah, Mourad Abed

The effective management of the allocation of limited resources such as beds is a key to the delivery of timely, high quality and low cost healthcare. However, an efficient utilisation of beds is not easy to accomplish because of the complexity of the healthcare system and the higher amount of…

Friction coefficients in cold forging: A global perspective

Peter Groche, Philipp Kramer, Niels Bay, Peter Christiansen, Laurent Dubar, K. Hayakawa, Chengliang Hu, K. Kitamura, Philippe Moreau

Worldwide, at least twenty different tribological tests have been proposed for the empirical determination of friction coefficients in cold forging processes. Due to the varying test setups, means of measurement, and level of abstraction, the comparability of the outcomes is, however, disputable.…

Optimization of the maintenance planning of a multi-component system

Issam Mallouk, Badr Abou El Majd, Yves Sallez

The vehicle’s maintenance costs, uptime and security are the most important goals for owners and transport companies, but these goals are conflictual and the major cause for delays is related to the maintenance policies. The main objective of transporters is to respond properly to their customer’s…

Predicting the different engine parameters of a rubber seed oil-ethanol dual fuel engine using artificial neural networks

J. Femilda Josephin, Edwin Geo Varuvel, Ankit Sonthalia, C. Bharatiraja, Fethi Aloui

The present study investigates the potential of artificial neural network for predicting the performance and emission characteristics of a compression ignition (CI) engine. A number of experiments are performed using diesel, rubber seed oil (RSO) and its methyl ester (RSOME) as the primary fuel,…

Sliding-Mode-Based Observer–Controller Structure for Fault-Resilient Control in DC Servomotors

Suneel Kumar Kommuri, Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu

This paper presents a robust observer-controller scheme for sensor fault-resilient control in dc servomotor drive-based applications (such as antennae control for satellite tracking, radio telescopes, and conveyor belt systems). In contrast to the earlier works on abrupt faults, this paper…
