Abstract: In the field of videosurveillance by calibrated cameras and locating objects of interest in images, a method uses, on the one hand, an initial presence map pCP1 modeling positions i in the scene and comprising, for each position i, a value pCP1(i) representative of the probability that an object is situated at position i considered, each value pCP1(i) being obtained a location criterion defined in an image space of the image acquisition system and, on the other hand, atoms Ai predetermined for each position i of the presence map pCP1, the atom Ai of a position i comprising, for each position j, a value Ai(j) representative of overlap between projection m?(i) in the image space of a three-dimensional model M?(i) placed at the position i and projection m?(j) in the image space of a three-dimensional model M?(j) placed at position j, each three-dimensional model being representative of an object.

Abstract: Catalytic process for the partial conversion of a gaseous mixture containing carbon monoxide and hydrogen into a mixture of hydrocarbons, including bringing the said gaseous mixture into contact with a solid catalyst, the solid catalyst having a porous support with a composite material including SiC and a titanium carbide and/or a titanium oxide, and an active phase. The support is prepared in the form of grains, beads, or extrudates, or in the form of cylinders or sheets of cellular foam.

Abstract: The invention relates to a photocatalyst comprising a ?-SiC cellular foam and a photocatalytically active phase, deposited directly on said cellular foam or on an intermediate phase deposited on said cellular foam. The average size of the cells is between 2500 ?m and 5000 ?m. The foam can comprise nanotubes or nanofibers (particularly of carbon, SiC, and TiO2) that consist of, or carry as an intermediate phase, a photocatalytically active phase.

Abstract: Methods, systems, devices and computer programs for configuring nodes on a wireless network can include generating a security key for the network, setting the security settings on the access point based on the security key, and saving the security key in a profile data file on a removable memory device along with a portable configuration utility for using the profile data file for configuring other nodes on the network. The removable memory device can then be inserted into other nodes and the portable configuration utility can be run to match the same key on the other network nodes based on the information stored in the profile data file on the removable memory device.

Abstract: The preparation of graphene, mono-, bi- and multi-layers from graphite-based precursor materials, for example, pencil lead or graphite, by a method of mechanical thinning on the surface of a planar substrate with controlled roughness, followed by sonication in order to collect the graphene deposited on the substrate in a liquid medium. The bearing force during thinning by mechanical friction enables the number of graphene sheets deposited on the surface of the substrate to be controlled.
