Abstract: Example solutions for performing federated graph queries use schemas and include: generating a logical graph using a query input and generating a physical plan using a query planning schema for double-nested loops, the outer loop for each permutation of data stores in a set of data stores, and the inner loop for each data store—ceasing when the logical graph has been fully consumed. A query cost is determined for each of the permutations, and a physical plan is selected based on the query cost, for example minimizing the query cost, and the query is executed based on the selected physical plan. The cost may be determined based on a weighted combination of factors such as freshness of the data, latency, power consumption, environmental impact (e.g., carbon footprint), energy efficiency, and network burden.

Abstract: A support structure of a wind turbine and a method of manufacturing the support structure is provided. A support structure of a wind turbine is disclosed, whereby the support structure includes a first end to connect to a rotor of a wind turbine, and a second end to be connected to a tower of a wind turbine. The support structure includes an intermediate part that connects the first end to the second end, and that the intermediate part includes the form of an elbow-shaped tube. The support structure is divided into at least two segments whereby the segments are transportable individually from a manufacturing site to a construction site. The segments are connectable in a way that the support structure is capable of transferring forces from the rotor to the tower.

Abstract: A liquid damper in a wind turbine is provided. A damper system of a direct driven wind turbine is disclosed, whereby the wind turbine comprises a nacelle, a rotor hub and an electric generator. The electric generator comprises a rotor and a non-rotating part. The rotor hub is connected to the rotor of the electric generator. The non-rotating part of the generator is connected to the nacelle. The wind turbine comprises a damper system to at least partially eliminate an unwanted movement of the wind turbine resulting from wind loads, whereby the damper system comprises a liquid damper. The damper system is arranged at a non-rotating part of the electric generator.

Abstract: A component for a brake system for a wind turbine generator is provided. The generator including a stator assembly, a rotor assembly and a rotation axis, wherein the rotor assembly includes an outer portion which is located radially outward of the stator assembly is provided. The component has the shape of a ring and includes a means for connecting it to a flange of the stator assembly. The component further includes a number of radially outwardly protruding portions including a means for connecting the radially outwardly protruding portions to frictional members operatively configured for frictionally engaging at least a portion of a brake disc and/or for connecting the radially outwardly protruding portions to a rotor lock system.

Abstract: The present invention consists of an apparatus for the on-line identification of drug effect using drug interactions and physiologic signals, in particular the interaction between anaesthetics and analgesics combined with the electroencephalogram for precise assessment of the level of consciousness in awake, sedated and anaesthetised patients. In a preferred embodiment the apparatus comprises: two infusion devices, for example syring pumps, which are connected to the patient (1) adapted to deliver hypnotics (2) and analgesics (3). The infusion data from the pumps are fed into an interaction model (5); an interaction model characterized by a Neural Network which is adapted to estimate the parameters of the model online and in real-time for drug interaction between anaesthetics and an analgesics, an EEG instrumentation amplifier; a processing unit adapted to calculate an EEG index of the level of consciousness (ELC); a fuzzy logic reasoner adapted to merge extracted EEG parameters into an index.

Abstract: An improved electronic circuit module retainer apparatus having interlocking, wedge-shaped components which are slotted and keyed together to allow tightening using a single screw which can be turned from the module insertion side of a module enclosure. A module retainer has a minimum of three interlocking parts which are held together by a tightening screw. A center body of the module retainer has holes for attaching it to a module or a module enclosure; it has a U-shaped channel with a square cross section and sloped ends. Each end body has a keying guide extending from a sloped end. A screw extends through a clearance hole in an end-body, then through the center body U-shaped channel and finally into a threaded hole in an opposite end body. When the screw is tightened, the end bodies slide along the sloped ends of the center body causing them to wedge the module against the module enclosure walls.
