Abstract: A method for predicting a surface condition of a road segment. The method including, for each system in a set of road weather information systems, training a predictive model on the basis of data originating from the system, applying each model trained for a particular system to the data originating from the other systems in the set of systems in order to determine a prediction error, grouping the systems according to a similarity in prediction error, associating a particular context with each group of systems and training a predictive model for each group of systems to which a context was associated. Also disclosed is a device for implementing the prediction method.

Abstract: There is disclosed an earth moving vehicle and a blade control assembly for an earth moving vehicle comprising a machine body, a push member comprising a first end pivotally mounted to the machine body for rotation about a lift axis and a blade pivotally attached to a second end of the push member for rotation about an angle axis. The assembly comprises a pair of linear actuators interconnected between the machine body and the blade. The blade is raised and lowered about the lift axis by respectively simultaneously retracting or extending both of said linear actuators and the blade is angled about the angle axis by extending or retracting a first of said linear actuators relative to a second of said linear actuators.

Abstract: A simple device for accurately measuring real-time air flows along a wall, and relating to a measuring device including an optical sensor configured to measure an illuminance distribution on a free surface of the optical sensor. A mobile member movably is mounted on the light sensor by partially covering its free surface, the mobile member being adapted to be freely directed by a local air flow pattern, thus, modulating the illuminance distribution on the free surface so as a current illuminance distribution measurement by the optical sensor indicates the current direction of the mobile member representing the current air flow pattern.

Abstract: A multilayer mirror includes a layer sequence arranged on a substrate and a plurality of layer pairs. Each layer pair includes a first layer composed of a first material and a second layer composed of a second material. The first layers and the second layers each have a thickness of more than 2 nm, and the first material or the second material is a silicon boride or a molybdenum nitride.

Abstract: In a multilayer mirror (1) for the reflection of EUV radiation containing a large number of alternating molybdenum layers (4) and silicon layers (3), a barrier layer (5) containing a silicon nitride or a silicon boride is included at a number of interfaces between the molybdenum layers (4) and the silicon layers (3). As a result of the barrier layers (5) of a silicon nitride or of a silicon boride, high thermal stability is achieved, in particular high long-term stability at temperatures of more than 300° C., whilst at the same time achieving high reflectivity in the multilayer mirror. A multilayer mirror (1) of this type can, in particular, be used as a heatable collector mirror for an EUV radiation source.
