Many Small and Medium Enterprises (SME) work as subcontractors (or co-contractors) for several clients for the design of mechanical components. During the design process, they must use a variety of Computer Aided Design (CAD) softwares and connect all the Product Data Management (PDM) systems of their customers. After defining the specific needs of these companies, we show that the available co...

Designing and implementing large, complex and distributed systems using semiautonomous agents that can reorganize and adapt themselves by cooperating with one another represents the future of software systems. This project concentrates on analyzing, designing and simulating such a system using the Organization Model for Adaptive Computational Systems (OMACS) metamodel. OMACS provides a framewor...

PURPOSE To determine the impact of Laparoscopic Sleeve Gastrectomy (LSG) on the resolution of type 2 diabetes (T2DM) and Prediabetes (PDM) in obese patients, as well as potential improvements in other comorbidities. MATERIAL AND METHODS Observational retrospective study. We studied all patients with T2DM (n= 36) or PDM (n= 44) who underwent LSG in our hospital between years 2009 and 2012. PDM...

Ordering ambiguity associated with the von Roos position dependent mass (PDM) Hamiltonian is considered. A PDM-pseudo-momentum operator Π̂1 = −i [μ (x)∂x + g (x)] is introduced (the Hermiticity of which is secured by the condition g (x) = ∂xμ (x) /2) and generalized to ddimensions. Intertwining our Hamiltonian, HMM = Π̂ 2 d + V (x), with the von Roos d-dimensional PDM-Hamiltonian, HvR = T̂d (α, β,...

The Point Distribution Model (PDM) has already proved useful for many tasks involving the location or tracking of deformable objects. A principal limitation lies in the fact that non-linear variation must be approximated by a combination of linear variations, resulting in a non-optimal model which can produce implausible object shapes. The Polynomial Regression PDM improves on the PDM by allowi...

Biographical notes: Christophe Merlo is an Assistant Professor in the Research Team of the Superior School for Advanced Industrial Technologies (ESTIA). After nine years as a Consulting Engineer involved in CAD/CAM and PDM projects, he joined the research team of ESTIA in 1999 and received his PhD from the University of Bordeaux 1 in 2003. This PhD dissertation dealt with the modelling of engin...

This work aims at investigating experimentally fretting corrosion, that is, corrosion induced by friction of AISI 316L SS against poly(methyl methacrylate) under small displacements, and subsequently using the data to model wear. The observed wear on the stainless steel has been modeled using the Point Defect Model (PDM). The originality of this approach in applying the PDM to fretting corrosio...

In this paper, we introduce a new tool, called a pseudodistance map (PDM), for extracting skeletons from grayscale images without region segmentation or edge detection. Given an edge-strength function (ESF) of a gray-scale image, the PDM is computed from the ESF using the partial differential equations we propose. The PDM can be thought of as a relaxed version of a Euclidean distance map. There...

CONTEXT Many studies have documented race and gender differences in health care received by patients. However, few studies have related differences in the quality of interpersonal care to patient and physician race and gender. OBJECTIVE To describe how the race/ethnicity and gender of patients and physicians are associated with physicians' participatory decision-making (PDM) styles. DESIGN,...
