Abstract: An apparatus for classifying a picture of a reaction of reactants in a predetermined container; the apparatus comprising a first neural network arranged for receiving an input picture of a reaction of reactants in a predetermined container and for providing, for each reaction category of a first plurality of reaction categories, a probability that the input picture shows a reaction that belongs to said reaction category; a second neural network arranged for, if the first neural response provides a highest probability that the input picture shows a reaction that belongs to a predetermined reaction category, receiving a predetermined portion of the input picture and providing, for each reaction category of a second plurality of reaction categories, a probability that said predetermined portion of the input picture shows a reaction that belongs to said reaction category.

Abstract: A self-erecting crane including a mast mounted on a rotating platform and supporting a boom is configurable between a transport configuration and a working configuration. The mast supports a hitch element suitable for being coupled on a fifth wheel provided on a rear platform of a tractor truck, the hitch element being located in a front hitch area of the mast which is dimensioned to come above the rear platform. The self-erecting crane also includes a mooring system located on the front hitch area and a removable ballasting element. In the transport configuration, the removable ballasting element is configured to be temporarily moored on the mast by the mooring system so that the removable ballasting element is located under the mast in the front hitch area. In the working configuration, the removable ballasting element is mounted on the rotating platform.
