Several new composite proton conducting polymer electrolyte membranes of different thicknesses (50-500 μm) based on polyvinyl alcohol (PVA), sulfosuccinic acid (SSA) and silicotungstic acid (SiWA) with or without silica have been developed for polymer electrolyte membrane fuel cells (PEMFCs). The chemical characterization of the membranes has been studied by Fourier Transform Infrared Spectroscopy (FT-IR). The thermal stability of the membranes has been studied using the techniques of thermogravimetric analysis (TGA) between room temperature and 600°C. The water uptake, ionic conductivity in NaCl solution and ionic exchange capacity of these membranes were determined. Water uptake of these membranes ranged between 31% and 88%. The ionic conductivities of these membranes ranged between 1.06.10-3 S.cm-1 to 6.72.10-1. The best water uptake and ionic conductivity were those of the membrane PVA-SSA-SiWA-10 SiO2 containing 10% of silica weight. The membrane PVASSA-SiWA have ionic conductivity of about 3.10.10-3 S.cm-1 in 1M NaCl, and generally increases with SiWA content, and reaches a maximum ionic conductivity of about 6.72.10-3 S.cm-1 in 1M NaCl for the membrane PVA-SSA-SiWA-10SiO2 The ion exchange capacity of this membrane was 1.75 mmol.g-1.

Risk assessment is an essential part of any occupational health (OH) management system. Occupational Risk Management Process, is characterized by multiple types of data (activity sector, occupations, risks exposures, diseases, etc.). This multidimensional aspect of data strengthens the need for appropriate tools to enhance OH analysis. This paper examines the opportunity of using spatial data warehousing technique in the OH management framework to integrate various data formats such as geographic (workplace data) and thematic data which are usually scattered across multiple, dispersed and fragmented systems. We propose a SOLAP architecture that supports the whole process of risk management for prevention purposes. We then instantiate the architecture to build a SOLAP-Based System for SMT Company to enhance risk assessment in OH for electrical and gas industries.

One of the main challenges in cloud computing is how to manage optimally the cloud resources in response of execution needs; so that both the cost and the time of running users applications are reduced. However, prices may change over time. In this paper, we propose an optimization-based solution which combines a Dynamic Genetic Algorithm (DGA) approach and fuzzy logic. First, we presented the DGA which provides a fair consideration of objectives. Then, we introduced a model based on possibility theory where each cost is taken as a fuzzy variable. For that, we used both possibility and necessity measures. In order to validate our solution, we tested it over some real applications using a set of cloud resources available on the market. The obtained results demonstrate clearly that our algorithms succeeded to find reasonable solutions that fulfill successfully our objectives function.

Language barriers are one of the biggest challenges that humans in general and children in particular face in their verbal interactions. Many reseach projets with mutli-countries scope are expected to give a significant help to teachers and doctors to support children with verbal communication disabilities by using humanoid robots. The usage of robot agent is excpected to stimulate the verbal communication based on natural language interactions with this kind of children. Such stimulation may be of great importance in improving the ability of these children to interact verbally with their teachers and classmates. In this context, we propose through this work to extend the language capabilities of humanoid robots to be able to communicate with children using differnet natural languages. This should allow a humanoid robot to recognize the spoken or written message of each children group and thus use this language to interact with. In this paper, we present the design of a generic models and the implementation of a software components to allow language neutral verbal interactions between children and humanoid robots. An extended ontology models will be provided to serve as a knowledge database of a set of concepts and theirs propoerties to represent the semantic aspects describing the relations between human-robot vebal communications. Based on thus generic models, we will provide an optimized new algorithms and their Python implementation to extend the natural language processing Python pakages. In this paper, a set of human-Robot verbal ineractions models are presented and the resultant conclusions and perspectives are discussed

Toughening requirements on reducing ship energy consumption and gas emissions raise the importance of the adoption of various energy-saving systems on marine engine and ship machinery design.Energy recovery from exhaust gases has a great potential considering the amount of mechanical or electrical work which could be generated onboard.This paper presents the study for the enhancement of the total energy efficiency of a vessel power-plant is developed by using a high-efficiency turbocharger. In this case, the study is focused on the Diesel operation mode of the engine to calculate the potential of energy that can be recovered from exhaust gas flow by the turbocharger.

In this paper, we study $H_{infty}$ performance for the descriptor systems with continuous-time. By using Finsler’s lemma technique and LMI approach, the sufficient condition is given in form of strict LMI for the problem that such descriptor systems are admissible with $H_{infty}$ disturbance attenuation level. Finally, a numerical examples are given to validate our results.

Industrial production workshops in all fields are becoming more and more robotized. Flexible workshops have several types of robots, namely mobile robots that move products from one machine to another, flexible cells are loaded and unloaded by robot manipulators. In this work we will discuss the design of a serial robot with six degrees of freedom. Three degrees of freedom to position the effector and three others to guide the wrist. In this context the manipulator arm must load and unload a CNC milling machine ‘TORMACH PCNC 440’ which is installed in our lab. The dimensions of the robot are adapted to the size of the machine, these organs are sized by another research team. In what follows we will discuss the different models allowing us the control of the manipulator. We start with the geometric model, the kinematic model and the static model. The goal is to enslave the arm in position and velocity. Several simulations have been carried out to validate this part of our study. Homogeneous transformation and modified DENAVIT-HARTENBURG (DH) parameters are adopted in this approach.

Collaborative robots (cobots) are presented as a way of business competitiveness by combining human skills with robotic advantages. The place of human operators in this context is the subject of much discussion. Including his role, his safety and his security. This study presents a methodological contribution for the management of cobotic projects. It aims to develop profitable, safe and acceptable solutions for the final users. This article presents the different steps of the design process of a collaborative robotic cell to improve a recycling laundry pods workstation. Initially, the current activity was analyzed through observations and interviews with users. Next, improvement scenarios were proposed, discussed and prioritized. After that, a feasibility study was carried out and led to technical prototyping. This was evaluated by end users to improve the solution before the investment.

Breast cancer is the second disease causing death in women. The screening of breast cancer for early detection is an effective way to reduce mortality. Generally, mammography is the most effective imaging modality recommended by radiologists. Therefore, a high number of mammogram images have to be analyzed. Indeed, the expertise of radiologists and the quality of the images to be analyzed play a crucial role in the accuracy of the diagnosis. The use of CAD systems allow improving the accuracy of diagnosis by reducing the number of false-positive and the false-negative. In this paper, to assist radiologists to make the right decision by showing them the probably suspect area, a full automatic CADe is presented. The preprocessing step aims at delimiting the ROI by removing artifact and pectoral muscle using global thresholding method, morphological operators and seeded region growing method, followed by contrast enhancement of the ROI found in the first step using the technique named “adaptive local gray level transformation based on variable s-curve”. At last, the ROI is segmented using k-means clustering. Both contrast enhancement method and the segmentation method are performed by genetic algorithm to optimize the outcomes of each step.
