Abstract: Methods and systems of active discovery and collaborative collision avoidance are described for aircrafts. Specifically, an aircraft predicts firstly the four-dimensional information of its short future flight path based on existing information, then shares the information actively among its adjacent aircrafts, realizes finally collaborative collision avoidance based on the future flight paths of adjacent aircrafts. The described methods contain the following steps: prediction and broadcast of short future flight path, broadcast reception and analysis and collision avoidance, and resumption of planned path and state. According to the methods, a system is also described to implement the above method and it contains seven corresponding modules. Since sharing the future information rather than the past information among aircrafts, the advantage of this intervention is strong real-time, low computation complexity, low cost, and more aircrafts accommodated in the same space.

Abstract: An ammonia decomposition apparatus comprises a casing, a heating zone, a heat exchange zone, a reaction section and a heat exchange coil. The heat exchange coil is spirally wound on an outer wall of the reaction section to efficiently heat ammonia gas. The reaction section has a first reaction zone and a second reaction zone communicated successively, the ammonia gas decomposed into a nitrogen-hydrogen mixture after entering the first reaction zone, with the second reaction zone decomposing for the second time the residual ammonia gas in the nitrogen-hydrogen mixture produced in the first reaction zone, so that the ammonia gas is decomposed more thoroughly. The conversion rate of ammonia gas can reach 99.9% or more, and the residual amount of ammonia gas in the nitrogen-hydrogen mixture can be less than 1000 ppm.

Abstract: An ammonia fuel cell system and an electric device are described. The ammonia fuel cell system includes an ammonia decomposition reaction device, a heating device, a hydrogen fuel cell, a DC/DC converter and an inverter connected successively, a battery pack and a heat exchanger. The heat exchanger of the system, can preheat ammonia gas by energy generated by ammonia decomposition, thereby recycling heat waste.

Abstract: Techniques are disclosed for a facial expression classification. In an embodiment, a multi-class classifier is trained using labelled training images, each training image including a facial expression. The trained classifier is then used to predict expressions for unlabelled video frames, whereby each frame is effectively labelled with a predicted expression. In addition, each predicted expression can be associated with a confidence score. Anchor frames can then be identified in the labelled video frames, based on the confidence scores of those frames (anchor frames are frames having a confidence score above an established threshold). Then, for each labelled video frame between two anchor frames, the predicted expression is refined or otherwise updated using interpolation, thereby providing a set of video frames having calibrated expression labels.
