Abnormal Detection in Big Data Video with an Improved Autoencoder.

With the rapid growth of video surveillance data, there is an increasing demand for big data automatic anomaly detection of large-scale video data. The detection methods using reconstruction errors based on deep autoencoders have been widely discussed. However, sometimes the autoencoder could reconstruct the anomaly well and lead to missing detections.

Assessment of AlN/Mg-8Al Composites Reinforced with In Situ and/or Ex Situ AlN Particles.

In this paper, 8.2AlN/Mg-8Al composites reinforced with in situ and/or ex situ AlN particles have been synthesized. The in situ-formed AlN particles are nano-sized, performing as particle chains.

Synthesis of an Al-Based Composite Reinforced by Multi-Phase ZrB, AlBC and AlO with Good Mechanical and Thermal Properties at Elevated Temperature.

To synthesize Al composite with high strength at elevated temperature, high modulus and thermal stability, ZrB, AlBC and AlO particles have been chosen as reinforcements simultaneously. A (9.2 wt.
