We introduce a computational framework for discovering regular or repeated geometric structures in 3D shapes. We describe and classify possible regular structures and present an effective algorithm for detecting such repeated geometric patterns in point- o ...
The title compound, Co(C20H23N3O2)(C5H11N) or [Co{(Me-sal)(2)dien}(pprdn)] BPh4, where (Me-sal) 2dien is 2,2'[1,1'-(3-azapentane-1,5-diyldinitrilo)diethylidyne]diphenolate and pprdn is piperidine, contains a pentadentate (Me-sal) 2dien ligand fu ...
Diffusion engineering has been proposed as an approach to increase the collected charge and energy resolution of a single-photon superconducting tunnel junction (STJ) spectrometer. We present new experimental results confirming this approach. When a photon ...
The flow investigation in a elbow draft tube is presented. After a review of the existing works related to the flow analysis of such component, the need of an experimental validation of the CFD tools is discussed with respect the practical interest of impr ...

We propose here some basic approaches to direct processing of the 360o-images as we take into consideration the geometry of each one. Obviously, the geometry of each of these images is a consequence of the geometry of the sensor's mirror used. This tech ...
Vascular remodeling is an adaptive response to variations in the hemodynamic environment acting on the arterial wall. Remodeling translates into changes of structure, geometry and mechanical properties of the artery. Our aim was to study the remodeling res ...
Superconductors of type-II are partially penetrated by magnetic flux, where the pinning of flux tubes constitutes a memory that gives rise to a hysteresis. However, the hysteresis gradually disappears when a transport current approaches the critical curren ...
High-temperature superconductors (HTS) exhibit hysteresis, which is the main cause for losses in the subcritical domain. This behavior is well predicted by Bean's critical-state model, which is a subset of the classical Preisach model. We present a paramet ...
This paper presents the basis of the modeling of the MOS transistor for circuit simulation at RF. A physical equivalent circuit that can easily be implemented as a Spice subcircuit is first derived. The subcircuit includes a substrate network that accounts ...
We present a new scheme for digital watermarking of point-sampled geometry based on spectral analysis. By extending existing algorithms designed for polygonal data to unstructured point clouds, our method is particularly suited for scanned models, where th ...
