Microstructures and properties of mortar using ammonium phosphate and potassium phosphate were tested and compared in this ***,two cementitious additions and two lightweight aggregates,including fly ash,redispersible latex powder,ceramsite sand,and rubber powder,were respectively tried to be applied in magnesium ammonium phosphate cement mortar in order to modify the microstructures and *** experimental results show that potassium phosphate is not suitable for magnesium phosphate cement mortar for cold region construction *** fly ash can bring positive modification in the condition of normal temperature curing,it brings negative effects in the condition of sub-zero temperature *** redispersible latex powder or ceramsite sand can improve the freeze-thaw cycling resistance of magnesium phosphate cement mortar in the conditions of low temperature coupled with freeze-thaw cycling,but only the ceramsite sand can improve both mechanical properties and freeze-thaw cycling *** modification caused by ceramsite sand is mainly due to the exceptional bonding strength between hardened cement paste and the porous surface of ceramsite and the porous structure of ceramsite for the release of frost heave stress.

Video analytics is essential in smart city management, traffic monitoring, and security surveillance, where real-time decision-making is critical. However, the efficiency of these applications depends on optimizing video compression parameters to maintain high detection accuracy while minimizing bandwidth usage and computational costs. This paper presents a comprehensive survey of video compression optimization techniques, focusing on Quantization Parameter (QP), Frames per Second (FPS), Entropy Coding, and Motion Estimation for video analytics tasks. We examine traditional compression algorithms, machine learning-based approaches, dynamic parameter adjustment strategies, and hybrid models, each offering unique strengths and limitations. Our findings highlight that adaptive compression techniques improve the trade-off between detection accuracy and efficiency. However, challenges remain, particularly in dynamic and bandwidth-constrained environments. To evaluate these techniques, we employ AccMPEG. This video compression framework dynamically adjusts compression settings based on real-time inference feedback, ensuring an optimal balance between detection accuracy and bitrate efficiency. In addition, we assess perceptual quality using Just Noticeable Distortion (JND) and Mean Opinion Score (MOS). The results indicate higher QP values lead to noticeable quality degradation, particularly at lower bitrates. Motion estimation techniques influence perceived quality, and TESA achieves MOS ratings higher than alternative methods. Furthermore, H.265 demonstrates superior MOS scores compared to H.264 at lower bitrates, reinforcing its higher compression efficiency while preserving visual clarity. Despite these advancements, the generalization of findings is limited, as the dataset consists mainly of traffic videos, which may not fully represent other video analytics applications. Future research should explore a broader range of datasets and develop adaptive compression frame
