Abstract: A method for predicting a property of a sample molecule involves, for each of a multitude of reference molecules, obtaining a multitude of fingerprints and at least one property, and obtaining the multitude of fingerprints of the sample molecule. The method further involves for each of the multitude of reference molecules, using each of the multitude of fingerprints, calculating distances to the sample molecule, and for each of the multitude of reference molecules, determining a relative predictive dominance, based on the distances to the sample molecule. The method also involves, for each of the multitude of reference molecules, determining a fitness value based on the relative predictive dominance, and predicting the at least one property of the sample molecule based on the at least one property of the multitude of reference molecules and the fitness values obtained for the reference molecules.

Abstract: Systems and methods include providing a user interface visualizing a current state of an optical network; receiving user inputs related to capacity mining in the optical network; determining a future state with the capacity mining based on the user inputs; and providing the user interface visualizing the future state. The future state can be presented with respect to a failed link and restoration of traffic on the failed link. The future state can include a plurality of plans with a visualization showing how much of the traffic is restored based on different approaches to the capacity mining. The capacity mining can include configuring optical modems based on determined available excess capacity.

Abstract: A robotic massage machine that includes at least one movable robotic arm having a first end effector, a processor that controls the movable robotic arm, a memory, a first body form having at least a first anatomical calibration point, a preprogrammed initial massage path based on the first body form, and a second body form having at least a first anatomical calibration point located in an analogous anatomical location as the first anatomical calibration point of the first body form. The processor is programmed to morph the initial massage path to calculate a calibrated massage path based on the second body form.

Abstract: An enclosure that provides a temporary sheltered service access area is disclosed. The outdoor electronics enclosure comprises a fixed cabinet which holds electronic equipment and a housing that is attached to the fixed cabinet with slide rails. The housing has a top panel, a service access door, two vertical panels, and a raised floor. The housing is movable from a closed position in which the housing is immediately adjacent to and partially surrounds the fixed cabinet to an open position in which the housing is moved away from the fixed cabinet in a horizontal direction to define an internal service access area within the housing for servicing the electronic equipment. Service technicians enter the sheltered service area and maintain electronic equipment in the fixed cabinet.

Abstract: An airfoil (26) for a gas turbine engine (10) having a source of heat for controlling a temperature gradient across the airfoil components. In one embodiment the airfoil includes a CMC outer body (28) defining an airfoil shape and a ceramic inner body core member (36) housed within and bonded to the outer body, and a heating element (54) disposed within the inner body core member. In another embodiment the source of heat may include a conduit (55) for delivering a flow of hot combustion gas from the combustor (14) to an interior of the airfoil. Heat energy may be delivered to the airfoil interior prior to or during startup of the engine in order to reduce the effect of temperature transients, during ongoing operation of the engine to reduce steady state temperature gradients, and/or during shutdown conditions to mitigate differential shrinkage between the core member and the outer body of the airfoil.

Abstract: An apparatus for mounting a refractory component such as a turbine shroud ring segment (32) with a ceramic core (42) onto a combustion turbine engine structure (34). The ring segment has a ceramic matrix composite skin (40), and optionally, a thermal insulation layer (46). A pin (60) is inserted through a bore (48) in the core and through an attachment bar (54) with ends received in wells (50) in the core. The attachment bar may be attached to a backing member, or tophat (64), by a biasing device (76) that urges the refractory component snugly against the backing member to eliminate vibration. The backing member and refractory component have mating surfaces that may include angled sides (52S, 70). The backing member is attached to the engine structure. Turbine shroud ring segments can be attached by this apparatus to a surrounding structure to form a shroud ring.

Abstract: A catalyst element (30) for high temperature applications such as a gas turbine engine. The catalyst element includes a metal substrate such as a tube (32) having a layer of ceramic thermal barrier coating material (34) disposed on the substrate for thermally insulating the metal substrate from a high temperature fuel/air mixture. The ceramic thermal barrier coating material is formed of a crystal structure populated with base elements but with selected sites of the crystal structure being populated by substitute ions selected to allow the ceramic thermal barrier coating material to catalytically react the fuel-air mixture at a higher rate than would the base compound without the ionic substitutions. Precious metal crystallites may be disposed within the crystal structure to allow the ceramic thermal barrier coating material to catalytically react the fuel-air mixture at a lower light-off temperature than would the ceramic thermal barrier coating material without the precious metal crystallites.

Abstract: Embodiments of the invention relate to a vane assembly formed by a forward airfoil segment and an aft airfoil segment. The aft segment is made of metal and can define the trailing edge of the vane assembly. The forward segment can be made of ceramic, CMC or metal. The forward and aft segments cannot be directly joined to each other because of differences in their rates of thermal expansion and contraction. The forward and aft segments can be positioned substantially proximate to each other so as to form a gap therebetween. In one embodiment, the gap can be substantially sealed by providing a coupling insert or leaf springs in the gap. A separate metal aft segment can take advantage of the beneficial thermal properties of the metal to improve cooling efficiency at the trailing edge without limiting the rest of the vane to being made out of metal.

Abstract: A ceramic insulating composition including monoclinic zirconia-hafnia. The zirconia-hafnia may be used as a filler powder (14) in a ceramic composition (10), or it may be used as a protective overlayer (50). The zirconia-hafnia (24) may be combined with alumina (22) to achieve a desired elastic modulus. The portion of hafnia contained in the zirconia-hafnia is selected to provide a predetermined phase transition temperature to minimize undesired phase changes during high temperature use of the material.
