The dimensioning of structures depends on the nature of the loading to which they are subjected. Load may be constant or, more generally, variable over the course of time. Take, for example, automobile suspension parts or the wings of a plane; their degree of stress in use varies. In fact, the phenomenon of fatigue concerns each object which surrounds us, and repeated use leads to their deterioration. Repetitive use and loading levels are determining parameters with regard to the lifespan of these elements, i.e. the period during which they function correctly. The main reason mechanics lack motivation for fatigue testing is the high cost of such tests. This is due, amongst other things, to the particularly dispersive character of the fatigue phenomenon and to the duration of the tests themselves. For each type of experimental checking in fatigue, this wide dispersion makes a considerable number of tests necessary in order to obtain representative results. Following up damage to the specimens according to the number of cycles in order to quantify the lifespan of the material was done using an infrared camera to evaluate the variation in temperature during the fatigue test. An approach to fatigue damage mechanisms, based on the treatment of dissipation images, is given. The endurance limit, obtained by energy method, is also shown. © 2011 John Wiley & Sons, Ltd.

The production of wine has progressed on every main continent. The knowledge modeling can support the sharing of expertise, methods and good practice concerning international grape vine growing and wine production while maintaining a high level of quality. Our research focuses specifically on the development of a support system for knowledge formalization. We describe some procedural rules to represent experienced knowledge in the viticulture domain and plant pathology. We use a graphical software for rules management. The visual representation is a step toward the improvements of interaction between Artificial Intelligence methods and domain experts to make interpretable learning models for concrete decisions. This implementation enables us to make valuable visual reasoning to search whether the Chinese regions are capable of receiving a production of French vineyards. In particular, one outcome is that two Chinese regions appear more favorable and consistent for the development of wine from the Bordeaux region. © 2014 Elsevier Ltd.

The verification and validation of information system models impact on the adequacy and appropriateness of using the value of telemedicine services for continuously optimizing healthcare outcomes. We have defined a methodology to help the modeling and rigorous analysis of the requirements of information systems in telemedicine. On one hand, this methodology will be based on a formal representation of requirements (systemic, generic domain, etc.) within a knowledge base that will be a requirements repository. On the other hand, this methodology will use conceptual graphs for the formalization of ontology of activities and the production of arguments related to the formal verification of models built from this ontology. We describe an example illustrating the engagement of conceptual graph procedures to model the contextual situations in the telemedicine development. We also discuss the way in which ethical issues will actually take place in telemedicine applications. © 2014 Elsevier Masson SAS. All rights reserved.

The complexity of the health care system is a particularly notable framework for the development of telehealth and telemedicine. It is therefore necessary to try to answer the relevant question that can be summarized broadly as "How to manage this complex system?" We will discuss here the relations between system engineering and telehealth, or more specifically how systems engineering can be applied in the design of a telehealth system, and what benefits it can bring in its development. This naturally leads us to think of methods you can use to understand the difficulty of decision-making and the conceptual perspectives. It has been an accepted fact that this first requires modeling, i.e. to construct a representation of the perceived reality through symbols and relevant rules, then to verify or validate in absolute terms this representation, model, so as to improve or be able to use it. The importance of this modeling and the rigorous analysis of the requirements of telemedicine systems are even more apparent since the recognition of the generic representation declined in two meta-models: the first covers the activities of teleconsultation, teleexpertise and teleassistance; the second concerns telemonitoring. © 2014 Elsevier Masson SAS.

In developing countries, telemedicine and mobile health tools promise to enhance access to high-quality healthcare, to support communication of medical information and to assist pharmacovigilance processes. In this article, we provide some arguments on the potential of telemedicine and mobile health (mHealth) applications to improve the delivery of health care in rural African regions. Specifically, the development of mobile telemedicine could help to lay the foundations of a healthcare approach integrating modern medical knowledge with ancient medical practices on the African continent. Access to information and communication technology (ICT), technical devices or portable media in developing countries is increasingly widespread. This can foster a complementary approach to healthcare, namely in African homebased care (AHC), in which the practice of conventional medicine takes place in an environment where belief in traditional medicine is strong. In the AHC, there are community volunteers who provide primary care and link patients with qualified medical personnel working in the nearest clinics and hospitals. These volunteers have contextual knowledge that is at the frontier of modern and traditional medicine, strongly influencing their practical approach to healthcare. The article proposes an interesting holistic look at potential applications of telemedicine in this context and examines in particular therapeutic and preventive education of toxicological aspects of medicinal plants and communication about the potential side effects of these plants. © 2014 Elsevier Masson SAS.
