A new method for functional assembly plan generation and evaluation. Implementation in CapLog, an efficient software
Autor: Christophe Perrard, Olivier Lehmann, Eric BONJOUR, Cyrille Dalla Zuanna
Designing an assembly system is a complex task that is broken down into different steps that deal with various representations of the product, the assembly plan and the assembly process plan. Each step faces a huge combinatorial explosion problem. Ma

Combining gradient ascent search and support vector machines for effective autofocus of a field emission-scanning electron microscope
Autor: Kamal Medjaher, Sounkalo Dembélé, Nadine Piat, Naresh Marturi, Olivier Lehmann
Publikováno v: Journal of Microscopy. 264:79-87
Autofocus is an important issue in electron microscopy, particularly at high magnification. It consists in searching for sharp image of a specimen, that is corresponding to the peak of focus. The paper presents a machine learning solution to this iss
