A sample selection method and apparatus and a server belong to the field of metric learning technologies. The method includes: selecting n sample pairs from an unlabeled sample set, each sample pair including two samples, and each sample including data in p modalities; calculating a partial similarity between data that is in each modality and that is of one sample included in the sample pair and data that is in each modality and that is of the other sample, to obtain p&#xd7;p partial similarities; calculating, according to the p&#xd7;p partial similarities, an overall similarity between the two samples included in the sample pair; obtaining a degree of difference between the p&#xd7;p partial similarities and the overall similarity; and selecting a sample pair that meets a preset condition and that is in the n sample pairs as a training sample. In this application, training samples of high quality are selected to train a metric model, so that the metric model of higher precision can be trained by using fewer training samples.

An antecedent determining method is performed by at least one processor, and includes obtaining statement information, and determining whether a pronoun exists in the statement information. The method further includes extracting candidate antecedents and lexical features of the candidate antecedents, from the statement information, in response to the pronoun being found in the statement information, and determining, based on the lexical features of the candidate antecedents, a target antecedent that is referred to by the pronoun, among the candidate antecedents.

An electric motor includes a stator having multiple magnetic poles and a rotor rotatably mounted to the stator. The rotor includes a shaft, a commutator and a rotor core fixed to the shaft; and windings wound on the rotor core and electrically connected to the commutator. The rotor core is formed by stacking a plurality of laminations. Each lamination includes an inner ring having a hole for fixing the shaft; an outer ring radially spaced from the inner ring; multiple teeth extending outwardly from the outer ring, and multiple ribs connecting the inner ring to the outer ring. Each rib has a width w measured in a circumferential direction of the lamination. The number of ribs is n. The width w and the number n satisfy the formula: 0.75&#x2264;n&#xd7;w&#x2264;64, where the width w is measured in millimeters.

An NFC antenna includes a first metal back cover and an antenna coil located on the inner side of the first metal back cover, a through-hole and a first slit are formed in the first metal back cover, the first slit is connected with one edge of the through-hole and one edge of the first metal back cover, the antenna coil surrounds the through-hole and the first slit, and one part of the antenna coil does not coincide with the first metal back cover and is not intersected with the first slit. Through the above manner, the effect of optimally changing the flow direction distribution and intensity of eddy currents can be achieved, the eddy current loops are used to enhance the performance of the antenna, and the shielding effect of the metal back is eliminated.

Disclosed are mechanisms for an impeller () and method of reducing noise levels while driving fluids with impellers. Exemplary implementations include a hub () and multiple blades () separably attached to or inseparably formed on the hub. The hub may be used to effectively reduce noise levels during operations of the impeller by having a first cylindrical feature (), a first number of first ribs (), and a second number of second ribs (), while maintaining substantially similar mechanical properties or operational characteristics. The hub may further optionally include a second substantially cylindrical feature () that is separably attached to or is inseparably formed on the hub to further enhance one or more properties or characteristics of the hub while serving to reduce the noise level of the impeller.

The present invention discloses a method for a core network to obtain user access information during a handover procedure, which includes: when the user handovers between HNBs or HeNBs and the core network does not carry out access control of the user, if the destination HeNB is connected to the core network directly or the user which does not support a closed subscriber group handovers to a hybrid destination HNB, the network element which controls the access of the user transmitting membership information of the user to the core network. The invention also discloses a corresponding system. The invention realizes that under the condition that the RAN side controlling the access of the UE during the handover process and the CN cannot know the membership of the UE, the RAN side notifying the core network of the membership information of the UE and the information of the H(e)NB.

A Method and apparatus for a user handing over to a home NodeB are provided. The method comprises the following steps: when the user initiates a handover procedure from a source NodeB to a target home NodeB, a target home NodeB gateway receiving a relocation request message from a mobility management unit of a core network; the target home NodeB gateway generating a user context for the user according to the relocation request message, allocating a user context identifier for the user context, and sending the user context identifier and the relocation request message to the target home NodeB; and when receiving a relocation request acknowledgement message replied by the target home NodeB, the target home NodeB gateway sending the relocation request acknowledgement message to the mobility management unit of the core network. The application of the above technical solution can ensure the handover of a user to a home NodeB which serves as a target NodeB successfully.

A window lift has a motor and a gearbox. The motor is a permanent magnet motor, comprising a stator and a rotor rotatably mounted to the stator. The stator or the rotor comprises a housing and magnets fixed to inner surface of the housing. The radial cross section of the housing comprises n side portions and n connecting portions, where n is an integer greater than 2. Adjacent side portions are connected together by one corresponding connecting portion and the magnets are fixed at portions corresponding to the connecting portions. The radial cross section of each side portion is like a convex curve line, which is curved outwardly relative to a straight line passing through the two ends of the convex curve line.
