Apprenticeships can offer apprentices, their teacher-tutors and business apprenticeship supervisors experiences that are rich in knowledge. The Success of Apprenticeships presents the observations and opinions of 48 actors regarding apprenticeships. These testimonies recount how apprenticeships allowed them to improve their expertise, their professional practices and their organization skills. This book also examines how their interactions in the work/study process allowed them not only to develop the skills of apprentices, but also the skills of those who accompanied them - the teacher-tutors and the business apprenticeships supervisors. The creation of an authentic community of apprentices subscribes to the formation of an ecosystem of learning, in which each individual harvests fruits in terms of the development of their personal abilities.
Three-dimensional surface meshes are the most common discrete representation of the exterior of a virtual shape. Extracting relevant geometric or topological features from them can simplify the way objects are looked at, help with their recognition, and facilitate description and categorization according to specific criteria. This book adopts the point of view of discrete mathematics, the aim of which is to propose discrete counterparts to concepts mathematically defined in continuous terms. It explains how standard geometric and topological notions of surfaces can be calculated and computed on a 3D surface mesh, as well as their use for shape analysis. Several applications are also detailed, demonstrating that each of them requires specific adjustments to fit with generic approaches. The book is intended not only for students, researchers and engineers in computer science and shape analysis, but also numerical geologists, anthropologists, biologists and other scientists looking for practical solutions to their shape analysis, understanding or recognition problems.
