Abstract: A computer implemented method predicts by a neural network a radio spectrum usage in an environment comprising interferers and a plurality of wireless nodes. The nodes operate via a slotted medium access control, MAC, protocol within a radio spectrum. The method includes the following steps: obtaining per slot the radio spectrum usage by sensing the radio spectrum, labelling the slots as usable when a respective radio spectrum usage is lower than a predefined noise threshold or when a node successfully transmitted a packet through it, unusable when it is not usable and suitable to receive a packet, and calculating a loss function as a cross entropy loss with the usable and unusable slots over a total number of usable and unusable slots, and training the neural network by minimizing the loss function.

Abstract: Methods are disclosed for producing an organic functionalized solid inorganic substrate, a surface of the inorganic substrate comprising a hydroxide and/or an oxide comprising an element M, the element M being a metal or a metalloid. The method includes drying the surface; optionally removing protons from the surface; and contacting the surface with an organometallic reagent comprising at least one organic functional moiety, thereby obtaining the organic functionalized inorganic substrate, the at least one organic functional moiety being attached to the element M of the hydroxide and/or the oxide by means of a direct M-C bond. The drying step includes contacting the surface with a flow comprising an inert gas. The organic functionalized inorganic substrate obtained by the method may be used as a membrane, a catalyst, a sorbent, a sensor or an electronic component, or as a substrate in filtration, adsorption, chromatography and/or separation processes.

Abstract: A method for estimating movements of a crowd between a first and second subregion in an area are monitored by a wireless sensor network. The wireless sensor network includes nodes configured to exchange a radio frequency signal through a first respective second link. The first respective second link crosses the first respective second subregion. The method includes the steps of exchanging radio frequency signals over the first and second link; and measuring respective first and second attenuations of the exchanged radio frequency signals over the first respective second link; and estimating based on a change in the attenuations a flow of the crowd between the first and second subregion. The estimating further includes estimating based on the first and second attenuations a density of the crowd in the first respective second subregion; and estimating based thereon a flux of the crowd between the first and second subregion.

Abstract: A method is provided for inspection of an item comprising acquiring a projection image of the item using a radiation imaging system and obtaining a plurality of simulated projection images of the item or a component thereof, based on a simulation of a numerical three-dimensional model. A relative orientation of the item with respect to the imaging system is determined by comparing the projection image to the plurality of simulated images, and at least one angle of rotation is determined by taking into account a viewing angle and the relative orientation. The method further comprises moving the item and/or the imaging system in accordance with the at least one angle of rotation and acquiring a further projection image of the item.

The swirl generator comprises a plurality of swirl channels configured for introducing a gas flow into the cavity as a vortex flow about the central axis, each swirl channel comprising a channel entrance and a channel exit. The swirl generator further comprises a gas redistribution chamber comprising one or more main gas supply inlets for receiving a gas, a distribution channel configured for distributing the gas received from the one or more main gas supply inlets to the channel entrances of the swirl channels, and one or more blocking walls configured for blocking and unblocking one or more entrances of the plurality of swirl channels. The vortex chamber is further configured for relatively rotating the channel entrances of the swirl channels with respect to the one or more blocking walls from a first angular position to at least a second angular position and vice versa, and wherein when in the second angular position the one or more blocking walls block a larger number of channel entrances than when in the first angular position.
