Abstract: A control system for a power distribution grid including an electrical distribution circuit includes a processor configured to perform operations including constructing a grid model comprising edges and nodes representing assets and transmission paths of the power distribution grid, generating an analysis of an operation of the power distribution grid over a predetermined time duration, determining a plurality of constraint violations based on the analysis of the operation of the power distribution grid within the predetermined time duration, generating a plurality of alterations to the power distribution grid, respective ones of the plurality of alterations resolving at least one of the constraint violations, selecting a first alteration of the plurality of alterations to the power distribution grid responsive to determining that the selected first alteration resolves at least two of the plurality of constraint violations, and autonomously implementing the first alteration to the power distribution grid.

Abstract: A manufactured thermally conductive granular backfill product compacted in a trench around an underground electrical transmission cable, the manufactured granular backfill product including a mixture of a granular base material having an R value which is higher than 1.2 when compacted, with a sufficient amount of an additive of a granular iron compound having an R valve which is less than 1.2 when compacted, so as to provide a manufactured thermally conductive granular backfill product having an R value of 1.2 or lower when compacted.

Abstract: A double-deck airplane that facilitates passenger embarking/disembarking and cargo loading/unloading operations in order to maximize the number of flight missions carried out in a given time. The floors of its upper and lower decks are planar surfaces extending continuously inside the fuselage in at least the inner space of the fuselage intended for the payload; the lower deck is located at a height from the ground that allows carrying out passenger embarking/disembarking via equipment incorporated in the airplane without any external airport ground equipment; passenger and/or cargo compartments are distributed on the upper and/or lower decks; and the lifting structure is disposed in the airplane in a manner that none of its components crosses the upper and lower decks.

Abstract: An aircraft including a wing, the end of the wing having a wing tip device, wherein the wing tip device includes a moveable region that is rotatable, about an axis of rotation extending out of the plane of the wing tip device, between: (i) a high-altitude cruise configuration in which the moveable region extends downwardly below the wing; and (ii) a ground-operating configuration in which the moveable region extends rearwardly behind the wing such that the ground clearance of the wing tip device is increased.

Abstract: The invention provides a double-deck airplane that facilitates passenger embarking/disembarking and cargo loading/unloading operations in order to maximize the number of flight missions carried out in a given time. Among other the airplane has the following features: the floors of the upper and lower decks (41, 43) are planar surfaces extending continuously inside the fuselage in at least the inner space of the fuselage intended for the payload; the lower deck (43) is located at a height from the ground that allows carrying out passenger embarking/disembarking autonomously without any specific airport ground equipment; passenger and/or cargo compartments (64, 63) are distributed throughout the upper and/or lower decks (41, 43); the lifting structure is disposed in the airplane in a manner that none of its components crosses the upper and lower decks (41, 43).

Abstract: Among other things, one or more techniques and/or systems are provided for placing an object, such as a user interface element within an interface, such as a graphical user interface (e.g., an application, a website, etc.). When placing the object, a visual state of an object may be transformed based upon initial drag movement of the object. Responsive to the initial drag movement exceeding a transformation threshold, the object is transformed into a precision placement object representing the object. The user may freely move the precision placement object within the interface. A precision point of the precision placement object may not correspond to a touch region of the precision placement object such that the user's finger, for example, may not obscure the object within the interface. Responsive to a placement input, the precision placement object may be transformed to the object, and the object may be placed within the interface.

Abstract: A webbing tie down assembly, comprising a clamping mechanism comprising: a first clamping member (309) having a first clamping surface (320), and a second clamping member.

Abstract: A vertical spindle type grinding mill for example for crushing coal comprises upper and lower rings 1, 2 together defining a track for rolling grinding members 3 and yokes 7, 4 bearing against the upper and lower rings 1, 2 for resisting forces tending to separate them. A drive is provided via main shaft 8, for effecting relative rotation between the rings. At least one yoke, preferably the lower yoke 4, bears against its associated ring 2 via interposed elastomeric material 6. This reduces the risk of brittle fracture when using hard relatively brittle alloys for the manufacture of the upper and lower rings so that they have increased wear resistance.
