Abstract: A smart landing platform system includes a flat and rigid platform for landing a drone and having a geometrical center, a center of gravity and a weight, a digital scale disposed beneath the platform for providing measurements of a weight distribution of the platform and the drone, and a control unit connected to the digital scale for instantaneous data collection and storing logic including a statistical inference algorithm based on a nonlinear least squares model to perform automated pre-flight safety check for the drone.

Abstract: Provide novel compounds of Formula (I) and pharmaceutical composition, pharmaceutically acceptable salt, prodrug, solvate, hydrate, tautomer, and isomer thereof, useful as FGFR inhibitors to modulate or inhibit the activity of FGFR enzymes. Further relates to, but is not limited to, methods for treating disorders associated with FGFR signaling with the compounds and compositions.

Abstract: A chassis end plate assembly of a railway vehicle is provided, which includes an end plate; a bottom beam arranged at an inner side of a lower edge of the end plate, curved beams arranged at inner sides of two sides of the end plate, a buffer beam located above the end plate; and a reinforcing beam longitudinally arranged between the buffer beam and the bottom beam. The end plate assembly can increase the rigidity of an end portion of the vehicle and improve the vibration mode. The end plate assembly can be combined with an under-vehicle active device compartment so as to form an enclosed space, which may protect pipelines and devices under the vehicle. A railway vehicle provided with the chassis end plate assembly is further provided.
