A stereo vision geometric descriptor for place recognition and its GPU acceleration for autonomous vehicles applications

In this paper we present a geometric global descriptor dedicated for place recognition in autonomous vehicles applications that is based on stereo camera generated point clouds. We first present the approach used to record the 3D structure of the…

Optimal energy management of offshore wind farms considering the combination of overplanting and dynamic rating

The electricity cost from offshore wind turbines has significantly declined over the past decade. However, in the context of energy transition, the further reduction in electricity generation costs remains a forefront subject. One possibility is to…

Identifying the physical features of basic sensory descriptors: the ultrasonic microrheology as a starting point

Foresee, or even design, the sensation produced by multiphasic materials like creams, gels or emulsions, as early as they are designed, is at stake for cosmetic industry, as it is the first feature evaluated by the consumer. The resort to experts…

Detection of alterations in historical violins with optical monitoring

Preventive conservation is the constant monitoring of the state of conservation of an artwork to reduce the risk of damage in order to minimise the necessity of restorations. Many methods have been proposed to achieve this goal, generally including…

Influence of plastic compression on the magnetic behaviour of a pipeline steel

Sensitivity of magnetic behaviour to plastic deformations is only documented in literature for uniaxial tensile testing and few models claim to take into account the plastic deformation sign. We present in this paper some new results showing the…

Analyse thermique à haute résolution spatiale par thermoréflectance de composants de puissance

The technological evolution of IGBT components requires a strong increase in power density. This increase in power density leads to very high temperature fields and gradients in the components and makes it necessary to know the thermal constraints…
