Abstract: An optometry apparatus measures optical characteristics of a subject eye. The optometry apparatus includes an objective measurement optical system that objectively measures the optical characteristics of the subject eye, a subjective measurement optical system that subjectively measures the optical characteristics of the subject eye, a first control means that performs first alignment processing based on a first alignment allowable range for determining a deviation between the subject eye and the objective measurement optical system, and a second control means that performs second alignment processing based on a second alignment allowable range for determining a deviation between the subject eye and the subjective measurement optical system. The second alignment allowable range has a wider allowable range than the first alignment allowable range.

Abstract: A method and an apparatus for detecting co-channel interference in a WLAN are provided. The method provided herein includes: A communication device detects a first energy value and a second energy value, where the first energy value is an energy value of a signal on a channel before a WLAN frame is sent, and the second energy value is an energy value of a signal on the channel after the WLAN frame is sent. The communication device determines, based on the first energy value and the second energy value, that the WLAN frame is subject to interference. This can detect co-channel interference on the channel with low complexity, without requiring information exchange between communication devices.

Abstract: State of art techniques hardly provide data balancing for multi-label multi-class data. Embodiments of the present disclosure provide a method and system for identifying cardiac abnormality in multi-lead ECGs using a Hybrid Neural Network (HNN) with fulcrum based data re-balancing for data comprising multiclass-multilabel cardiac abnormalities. The fulcrum based dataset re-balancing disclosed enables maintaining natural balance of the data, control the re-sample volume, and still support the lowly represented classes there by aiding proper training of the DL architecture. The HNN disclosed by the method utilizes a hybrid approach of pure CNN, a tuned-down version of ResNet, and a set of handcrafted features from a raw ECG signal that are concatenated prior to predicting the multiclass output for the ECG signal. The number of features is flexible and enables adding additional domain-specific features as needed.

Abstract: Die Erfindung betrifft eine elektrische Maschine mit einem Läufer in einem ortsfesten Maschinengehäuse, der eine supraleitende Erregerwickiung und ein zylindrisches Wellenendstück enthält. Um das Wellenendstück ist ein nicht-rotierendes Anschlußkopfteil angeordnet. Zwischen diesen Bauteilen sind ein Lager und eine Dichtungsvorrichtung vorgesehen und wird ein Kühlmittel übergeleitet. Der Läufer einer solchen Maschine führt axiale und radiale Schwingungen aus. Ist der Anschlußkopf starr mit dem Maschinengehäuse verbunden, muß die Dichtungsvorrichtung ein entsprechendes Spiel ermöglichen. Dies führt jedoch zu Abdichtungsschwierigkeiten. Die Erfindung sieht deshalb ein Lager (22; 25) mit so geringem radialen Spiel vor, daß das Anschlußkopfteil (2) den radialen Auslenkungen des Wellenendstückes (3) aus dessen Sollage bezüglich einer Rotationsachse (4) folgt. Die Dichtungsvorrichtung (29; 30) kann dann vorteilhaft eine Ferrofluidikdichtung (50 bis 52) sein. Als Lager (22; 25) kommt insbesondere ein Gleitlager in Frage. Entsprechend gestaltete Anschlußkopfteile können für supraleitende Turbogeneratoren vorgesehen werden.

Abstract: A method of producing a composite material from porous reinforcing material and molten matrix metal. First the porous reinforcing material is heated to a temperature substantially above the melting point of the matrix metal. Then the molten matrix metal is infiltrated into the porous structure of the reinforcing material under a substantial pressure. Then the combination of the reinforcing material and the matrix metal infiltrated thereinto is cooled down to a temperature below the melting point of the matrix metal, while maintaining the above-mentioned substantial pressure. Optionally, the reinforcing material may be charged into a case; and, again optionally, the case may have one opening only, and a vacant space may be left between another part of the case and the reinforcing material charged in the case, with the reinforcing material interrupting communication between the opening and the vacant space. The case can be made of stainless steel, or of a refractory material such as porous brick. Alternatively, the reinforcing material may be restrained by ties or tapes clamped on it. Possible materials for the reinforcing material include fibres of alumina, carbon, boron, or stainless steel, and possible materials for the matrix metal include aluminium and magnesium.
