Abstract: A computer-implemented method for building a diagnostic module for a physical system includes obtaining simulated healthy measurements by a physics-based simulation model of the physical system from measured input excitations to the physical system. The method includes training a generator model to generate realistic healthy measurements from the simulated healthy measurements and the measured input excitations, the training involving tuning the generator model based on an error between a generated realistic healthy measurement and a corresponding real measurement obtained from the physical system in response to each input excitation. The trained generator model is used to generate realistic faulty measurement data from simulated faulty measurements obtained by the physics-based simulation model. The method includes training a classification model using a training dataset augmented by the realistic faulty measurement data generated by the generator model, to be able to predict health of the physical system during operation from measured operational data.

Abstract: A computer-implemented method includes operating a first autonomous system to perform a task based on executable code derived from objects in a world model of the first autonomous system. The world model objects of the first autonomous system represent an operating environment of the first autonomous system. The method includes determining an initiation trigger when the first autonomous system is to begin interaction with a second autonomous system. The second autonomous system is operated based on executable code derived from a world model that includes world model objects representing an operating environment of the second autonomous system. After the initiation trigger, the method includes sharing of the world model objects between the first and second autonomous systems. Subsequently, the method includes continuing operating the first autonomous system based on an extended world model of the first autonomous system that includes the shared world model objects of the second autonomous system.

Abstract: A system for obtaining information about an Internet of Things (IoT) device connected to a network includes a data traffic collection point, a data processing module and an artificial intelligence module. The data traffic collection point collects data units communicated to or from a specified IoT device of a plurality of IoT devices connected to a network. The data processing module processes quantitative information pertaining to the data units communicated to or from the specified IoT device collected over a defined time interval, to create a temporal data traffic fingerprint of the specified IoT device. The artificial intelligence module utilizes a machine learning model to deduce device identifying information of the specified IoT device from the temporal data traffic fingerprint of the specified IoT device.

Abstract: In a computer-implemented method for geometric feature recognition, a digital representation of a first and a second 3D shape is obtained. The digital representation includes a polygon mesh describing a surface of the respective 3D shape. For each 3D shape, the polygon mesh is segmented into a set of surface patches. Each surface patch includes a cluster of faces of the polygon mesh fitted to a geometric primitive from a finite set of geometric primitives. A primitive graph is constructed, composed of nodes representing the surface patches with associated geometric primitives and edges representing common boundaries between the surface patches in the polygon mesh. A common geometric feature is identified between the first and second 3D shapes based on a matching of a pattern of subgraphs in the primitive graphs associated with the first and second 3D shapes.

Abstract: A locking device (106) for a railway switch (100) includes a main structural member (202) adapted to withstand stress loading and a replaceable guide member (204). The main structural member (202) is configured to be fastened to a stock rail (102). The guide member (204) is detachably coupled to the main structural member (202). The guide member (204) defines, at least in part, a channel (212) extending from a first end (206) to a second end (208) thereof. A locking face (126) is defined at the second end (208) of the guide member (204). Upon installation, the channel (212) is configured for guiding therethrough a simultaneous motion of a latch member (114) and an operating bar (110) of the railway switch (100). The latch member (114) has a first end (116) coupled to a switch blade (104) and a second end (118) configured as a lock catch. The locking face (126) is configured to bear against the second end (118) of the latch member (114) to lock the switch blade (104) to the stock rail (102).

Abstract: A bladed rotor system (10) for a turbomachine includes a circumferential row of blades (14) mounted on a rotor disc (12), and includes a plurality of under-platform dampers (30). Each damper (30) is located between adjacent blade platforms (24). The plurality of dampers (30) includes a first set (H) of dampers (30) and a second set (L) of dampers (30). The dampers (30) of the first set (H) are distinguished from the dampers (30) of the second set (L) by a cross- sectional material distribution in the damper (30) that is unique to the respective set (H, L). Dampers (30) of the first set (H) and the second set (L) are positioned alternately in a periodic fashion in a circumferential direction, to provide a frequency mistuning to stabilize flutter of the blades (14).

Abstract: An analytic tool (10) useful in predicting drive-train over-speed under a large number of different loss of load scenarios, as well as under a number of different engine and drive- train configurations, is provided. The tool and its associated method of use allows for a designer to model various sets of fuel control system parameters (20), simulate operation of the gas turbine power generation units (120) and then select an optimum operating point and associated fuel control system (20) that provides the best assurance that over-speeding will be prevented for the intended operating conditions (130). The fuel control system parameters (20) may include, but are not limited to, the isolation valve design (22) and the piping configuration (24,28) of the fuel control system (20).

Abstract: Outboard-transverse flame migration in an annular profile combustion gas pathway (22) of an aeroderivative turbine engine (10) is detected with a dual-immersion thermocouple probe (32). A first thermocouple (34) in the probe is oriented radially midway between inner (24) and outer (26) circumferential surfaces that define the pathway. A second thermocouple (36) in the probe is oriented nearer to the outer circumferential surface of the pathway. A controller (38) detects outboard-transverse flame migration in the combustion gas pathway, when the second thermocouple temperature exceeds the first thermocouple temperature. An outboard-transverse flame migration detection and control system for an aeroderivative turbine engine comprises an aeroderivative turbine engine (10) having a combustion gas pathway (22) and a dual-immersion thermocouple probe (32) oriented in an inter-turbine duct (20) of the exhaust section of the pathway. The dual-immersion thermocouple probe comprises an elongated probe housing, a first thermocouple in the probe housing proximate a housing tip, for generating a first signal (S1A), and a second thermocouple in the probe housing proximate a housing base, for generating a second signal (SIB). A Controller (38) is separately coupled to the first and second thermocouples for receiving the separate first and second signals and correlating the received first and second thermocouple signals with exhaust gas temperatures in the combustion gas pathway proximate the respective thermocouples.
