摘要： The invention discloses a Transformer-based multi-scale pedestrian re-identification method. The present invention proposes a pedestrian re-identification network based on multi-scale pedestrian feature extraction and Transformer. Firstly, we designed a multi-scale feature cascade module, which aims to mine detailed feature information of pedestrians at different depths and scales, so as to obtain stronger feature representation. Secondly, we constructed a feature extraction based on Transformer to learn pedestrian features at a global scale. Finally, the features output by the Transformer are aggregated to obtain a better expression of pedestrian features, thereby improving the discrimination ability of the model. The result shows that this method has better robustness and adaptive ability, and effectively enhances the generalization ability of the model.

摘要： A detonator for an explosive material is described. The detonator includes a semiconductor bridge, coupled with the explosive material, including thermal feedback mechanism is provided via one or more thermistors. An exemplary mechanism includes a semiconductor bridge with a polysilicon resistor and a pair of thermistors. The two thermistors are disposed to be substantially close to or sandwich the polysilicon resistor. When the temperature surrounding the polysilicon resistor is getting upwards, the temperature surrounding the thermistors is equally going up. When the temperature reaches a critical point, but below the threshold of the polysilicon resistor, the resistance of the thermistors drops suddenly or drastically, causing the current driving up the temperature of the polysilicon resistor to divert through the VOX temp resistors. Subsequently the current going through the polysilicon resistor is reduced, causing the temperature to drop downwards.

摘要： The present disclosure discloses a cross-session brainprint recognition method based on a tensorized spatial-frequency attention network (TSFAN) with domain adaptation. For most of existing multi-source domain adaptation methods, domain gaps between multiple source domains and target domains are individually bridged, but a relationship between domain-invariant features in distribution alignment is ignored. The present disclosure assists performance of a target domain by modeling an important relationship of the domain-invariant features without being affected by a distribution difference between source domains. A new TSFAN is used to combine pairwise source and target and an appropriate common spatial-frequency feature across source domains. Considering of a dimension, the TSFAN is further approximated as a low-rank Tucker format, to enable the TSFAN to adapt to scale linearly in a quantity of domains, and apply the TSFAN to a case of any quantity of sessions.
