Data fusion strategies for reducing the uncertainty of point cloud data

For decades, contact probes on coordinate measuring machine (CMM) have been widely used for data acquisition in coordinate metrology, mainly because of their high accuracy. However, the acquired data is a low-density set of points, because sampling using a contact probe is a slow process. Nowadays, optical 3D scanning technologies such as structured-light scanners or […]

Optimization of furnace residence time and loading pattern of large size ingots inside a gas-fired forging furnaces

Large size high strength steels parts used in transport and energy applications undergo several heating and cooling cycles during their manufacturing process (casting, forging, quench, tempering). Generally, before forging the parts are heated in gas-fired forging furnaces and the impact of non-uniform heating on the subsequent steps is of critical importance. A non-uniform temperature distribution […]

ELSTec : Efficient lightweight structures made by automated fiber placement (AFP) of thermoplastic composites

Led by Prof. Steve Tsai from Stanford University, Palo Alto, USA, new methods to efficiently design, analyze, optimize and manufacture high-performance light weight panels made of carbon fiber reinforced composites and thermoset resins have been developed by an international consortium. The ideas already available give indication to massively reduce cost, maximize light weight efficiency and […]

The Physical Conditions of Gas In Ultra-Luminous Infrared Galaxies

The single most important factor in determining a star’s brightness, evolution and ultimate fate is its mass. For this reason, the determination of many intrinsic galaxy properties – including star formation rate – must assume an initial distribution of birth masses for stars. If we are to develop a general theory for star formation in […]

CFD methodology for analysis of multiphase flow process

Oil that has passed through the bearings and gearboxes of aircraft engines is recycled by a specialized oil scavenging system that separates droplets dispersed from the shaft from air and particulate matter. This process helps to mitigate the emissions of aircraft engines, greatly improves oil consumption and Improves working life by improving the cooling capabilities […]

Simulation of consolidation-driven defects in woven fabric pre-pregs

Woven fabric-reinforced polymers (WFRP) are composite materials consisting of interwoven fibers dispersed in a continuous polymeric matrix phase. Lightweight and yet very strong mechanical characteristics of WFRPs are, however, often disadvantaged by poor quality due to manufacturing defects. The proposed project aims to exploit the simulation tools developed at University of Bristol to simulate the […]

Development of Computational Fluid Dynamics Methodology for Management of Oil Tanks and the Separation of Air and Oil in an Aero-Engine

Oil is used in aircraft engine applications to lubricate and carry the associated parasitic heat generated away from the moving components. Inefficient lubrication can cause an increase of heat transferred to the metal components by friction while too much oil can cause an increase of the heat generation by churning. The churning of oil leads […]

Implémentation et validation d’une approche multi-échelle pour la réponse matérielle en phase de rentrée atmosphérique

Les boucliers thermiques servent à protéger les véhicules spatiaux des fortes contraintes thermiques auxquels ils sont soumis lors de la phase de rentrée atmosphérique. En dissipant cette énergie par plusieurs mécanismes physiques, ils garantissent l’intégrité du véhicule. Afin de mieux les comprendre, on se propose ici de réaliser une étude numérique en simulant ces différents […]

Tightly-coupled Visual-Inertial-LiDAR SLAM

Since Amazon robotics expanded the use of drones to package deliveries to customers, drone applications have been expanded to many industries along with its ability to perform various tasks autonomously. The fundamental technology of drones’ autonomy comes from perceiving its surrounding, creating its own map based on onboard sensors and estimate its location within the […]
