Abstract: Provides is a method for detecting a complex target in pedestrian re-identification video streams based on an event-related potential (ERP). According to the method, video streams of a complex target in different scenarios are collected, and are made into experimental paradigms, and electroencephalogram (EEG) data of a subject during watching of a video content is collected. Then brain electrical activity mapping (BEAM) is analyzed, and ERP features are marked, including P300 and P300-D, which correspond to target emergence and target disappearance respectively. Positive and negative sample pairs are constructed, and essential features between classes are obtained based on a method of contrastive representation learning and a method of spatial-temporal feature attention extraction, so as to solve the extreme class imbalance problem of samples and the problem of how to distinguish between two similar classes in a video paradigm.

Abstract: An electric stimulation method based on inspiration of healthy side lower limb muscle synergy and a system thereof are provided. A motion process of a healthy side limb of an individual is analyzed, and in combination with an electromyographic signal and a motion posture signal, a muscle motion model which is more in line with coordination of an individual's own limb is established, and the healthy side limb muscle motion model is used to guide the affected limb to move. Inspired by the healthy side limb of an individual, the electromyographic signal and the motion posture signal of the healthy side limb are acquired, and the motion model of the healthy side limb is established. The change relationship of the muscle synergy activation degree with the time is mapped as the change relationship of the muscle synergy activation degree with the angle, which eliminates time-varying interference.

Abstract: The present disclosure relates to a traceable in-situ micro- and nano-indentation testing instrument and method under variable temperature conditions. A macro-micro switchable mechanical loading module, a nano mechanical loading module and an indentation position optical positioning module are fixed on a gantry beam, an optical imaging axis of an optical microscopic in-situ observation or alignment module and a loading axis of the nano mechanical loading module are coplanar, the optical microscopic in-situ observation or alignment module and the function switchable module are mounted on a table top of a marble pedestal, and a contact or ambient mixed variable temperature module is fixedly mounted on the function switchable module. A modular design is adopted, the micro- and nano-indentation testing instrument is used as a core, in combination with a multi-stage vacuum or ambient chamber, an indentation depth traceability calibration module and multiple sets of optical microscopic imaging assemblies.

Abstract: A flare-type tension leg floating wind turbine foundation is provided, which includes a top support platform configured to support a tower frame, a blade and a wind turbine generator set; a bottom support structure connected to a plurality of tension legs; at least three hollow upright columns connected between the top support platform and the bottom support structure and arranged around a vertical center line of the floating wind turbine foundation, each of the at least three upright columns being inclined outward from a lower end to an upper end with respect to the vertical center line of the floating wind turbine foundation; and a ballast adjusting system provided in the upright columns and/or the bottom support structure.

Abstract: A water valve and a drinking device are provided. The water valve includes an upper support, a lower support, a valve spool, a sealing member, a spring and a water outlet. The upper support is provided with a water inlet. The lower support is provided with a water outlet and a vent hole. The valve spool has a first end connected with the upper support and a second end fixedly connected with the lower support, and the valve spool is movable relative to the upper support, to switch on or off a communication between the water inlet and the water outlet. When the water valve is at a state of discharging water, an interior of the water outlet pipe is not communicated with atmosphere; when the water valve is at a state of not discharging water, the vent hole communicates the interior of the water outlet pipe with the atmosphere.
