Abstract: A method of repairing a divertor or first wall surface in a tokamak plasma vessel. The divertor or first wall surface comprises a refractory metal having a melting point of at least 2000° C. A pressure of less than 25 mbar is maintained within the plasma vessel following the end of operation of the plasma vessel. The refractory metal is deposited onto the divertor or first wall surface within the plasma vessel via a deposition process which is one of: additive manufacturing; physical vapour deposition; thermal spray; arc ion plating; diode laser cladding; and chemical vapour deposition.

Abstract: A method for computing a required speed profile for an aircraft to meet a required time of arrival (RTA) for a waypoint of a current flight is provided. During flight, the method calculates a fuel-efficient speed profile for the aircraft to meet the RTA for the waypoint, by a processor of a computing device communicatively coupled to one or more avionics systems onboard the aircraft; activates the fuel-efficient speed profile to fly the aircraft to the waypoint, by the processor; determines a priority between fuel efficiency of the fuel-efficient speed profile and time reliability, by the processor; and when the priority is the time reliability, switches from the fuel-efficient speed profile to a guidance margin control strategy to fly the aircraft to the waypoint, wherein the guidance margin control strategy increases the time reliability by enabling the aircraft to satisfy constraints of the RTA.

Abstract: Methods and systems are provided for enhancing the functionality of an airborne separation assurance system (ASAS) by modifying it to cooperate with a required time of arrival (RTA) functionality. The system comprises an autopilot configured to execute a trajectory of an aircraft and a flight management system (FMS) in operable communication with the autopilot. The FMS includes a required time of arrival (RTA) system that is configured to determine an RTA aircraft trajectory of the aircraft based on a required time of arrival of the aircraft at a waypoint along the flight plan. The system also includes an airborne separation assurance system (ASAS) in operable communication with the RTA and is configured to determine a spacing trajectory based on a spacing interval from a first reference aircraft.

Abstract: A method is provided for controlling speed of a vehicle. The method includes determining an arrival time error (ATE) for a required time of arrival (RTA) and a projected trajectory according to a travel plan with a current speed profile having a plurality of regions, each with a respective speed adjustment parameter (SAP) and a respective SAP value relative to a nominal speed profile. The method further includes selecting, when the ATE is greater than a threshold, one of the regions as a selected region for modification based on a priority order of the regions. The method further includes modifying the current speed profile by adjusting the respective SAP value for the selected region according to the respective SAP in order to decrease the ATE; and implementing the modified speed profile.

Abstract: A controller has two irrigation station module connection areas within it and can either accept two irrigation station modules at the same time or one larger module that spans both connection areas. The larger module, however, includes more irrigation station terminals than both of the smaller irrigation station modules combined. Therefore, a greater number of irrigation stations can be connected to the controller when the larger module is substituted for the two smaller modules.

Abstract: A latex coating composition is disclosed, comprising a latex polymer binder; water; and a ketal adduct of formula (1) wherein R1 is C1-6 alkyl, R2 is hydrogen or C1-3 alkyl, each R3, R4, and R5 is independently hydrogen or C1-6 alkyl, R6 and R7 are each independently hydrogen or C1-6 alkyl, a is 0-3, and b is 0-1.

Abstract: A method and apparatus includes long term and short term strategies for improving 4D trajectory reliability and required time of arrival reliability. The long term strategy changes speeds along the trajectory to remove the time error in predictions. The short term strategy compensates for wind and position error, for example, by temporarily changing an aircraft guidance speed by applying a guidance margin that would either delay or prevent re-computation of the speed targets along the flight path. The predictions would use the original speed target without the guidance margin application. The guidance speed target will stay applied until the predicted time error crosses a threshold.

Abstract: A water-reducible coating composition includes a water-reducible polymer binder; water; and a ketal adduct of formula (1) as well as coated substrates and films formed from the compositions. The films are useful as paints, stains, and clear-coats.

Abstract: A system is provided for controlling the speed of an aircraft during a deceleration segment between a first state associated with a first speed and a first time and a second state associated with a second speed and a second time. The system includes a navigation system configured to determine the first state; a guidance system configured to determine the second state; and an active deceleration system coupled to the navigation system and the guidance system and configured to construct the deceleration segment between the first state and the second state with at least one intermediate speed between the first speed and the second speed.

Abstract: Methods, systems and device are provided for smoothing a required time of arrival (RTA) speed transition for an aircraft in a multi-segmented speed profile including at least one preceding region with a first predetermined speed pad and at a speed constrained region with a second predetermined speed pad. Exemplary methods include, but are not limited to determining whether a speed constrained region is engaged by a preceding region based at least in part on a speed of an aircraft. If the speed constrained region is engaged, the instructions determine a revised second speed pad for the speed constrained region. If the speed constrained region is not engaged then the instructions assign a default speed pad as the second speed pad for the speed constrained region.
