Abstract: A system includes one or more processors that are configured to obtain a constraint on movement for a first vehicle system along a route. The constraint is based on movement of a separate second vehicle system that is concurrently traveling along the same route. The processor(s) are configured to determine a speed profile that designates speeds for the first vehicle system according to at least one of distance, location, or time based on the constraint such that the first vehicle system maintains a designated spacing from the second vehicle system along the route.

Abstract: This application describes a thermal interface material, and preparation and application thereof. Specifically, a thermal interface material is described. The thermal interface material is obtained by bending and folding, optional horizontal pressing and optional high-temperature treatment of a laminated structure. Two-dimensional high-thermal-conductivity nano-plates on the upper surface and the lower surface of the thermal interface material have a horizontal stack structure. Two-dimensional high-thermal-conductivity nano-sheets located between the upper surface and the lower surface of the thermal interface material have both a vertical stack structure and a curved stack structure. Also described are a preparation method and application of the thermal interface material.

Abstract: Mechanical condition monitoring of robots can be used to detect unexpected failure of robots. Data taken from a robot operation is processed and compared against a health baseline. Features extracted during the monitoring stage of robot operation are aligned with features extracted during the training stage in which the health baseline is established by projecting both onto a common subspace. A classifier which can include a distance assessment such as an L2-norm is used within the common subspace to assess the condition of the robot. Excursions of the distance assessment from a criteria indicate a failure or potential failure.

Abstract: According to some embodiments, data associated with the operation of a desalter vessel (150), adapted to receive a raw crude input and a water input and facilitate creation of a desalted crude output and a salt water output, may be stored in a computer storage device (630). A computer processor (610) may determine at least one parameter associated with the data in the computer store. The computer processor (610) may then automatically calculate, based on the determined parameter and a physics-based dynamic desalter model (400), an adjustment value for a second parameter associated with operation of the desalter vessel. Using the automatically calculated adjustment value, the computer processor (610) may automatically generate and transmit an indication of the adjustment value so as to improve operation of the desalter vessel (150).

Abstract: A vehicle control system and method determine one or more designated speeds of a trip plan for a trip of a vehicle system along a route. The trip plan can designate the one or more designated speeds as a function of one or more of time or distance along the route for the trip. Geometry of the route that the vehicle system will travel along during the trip is determined, as well as one or more prospective forces that will be exerted on the vehicle system during movement of the vehicle system along the route for the trip based at least in part on the geometry of the route. The trip plan is revised to reduce at least one of the prospective forces by reducing at least one of the designated speeds of the trip plan based on the one or more prospective forces that are determined.
