Based on panel data from 210 prefecture-level cities in China 2003 to 2021, this study employs the Time-Varying Differences-in-Differences (Time-Varying DID) approach systematically examine impact of smart city construction pollution emissions and its underlying mechanisms. Additionally, Propensity Score Matching-Differences-in-Differences method is employed for further validation. The research findings indicate that Smart City Construction (SCC) significantly reduces urban Volume Sewage...
Fire accident investigation has always been difficult, because of complexities fire occurrence and development the non-repeatability similar accidents. In this study, a method is proposed based on computer-aided scene reconstruction technique, realizing an effective combination computer simulation. Based traditional material evidence, uses technique to reconstruct its catastrophe process through Then, was successfully used investigate case study taking place in multi-story residential...
Accurate measurement of fire source heat release rate is crucial for comprehensively understanding the evolution process. However, widely used oxygen consumption method requires expensive equipment, incurring high costs. This study proposes a comprehensive framework based on machine learning to predict using temperature as input. Firstly, scenarios with different parameters in ISO9705 room were simulated FDS software obtain at various locations, establishing database. Then, two recursive...
Summary Temperature fields analysis is an essential work to evaluate the behavior of structures in fires. Large space buildings are mostly highly populated or high‐fire load places with high fire risks. So it a research focus predict temperature large fires accurately. In this study, full‐scale physical experiment on spaces has been conducted. The results show that distribution natural nonuniform. With regard evolution laws spaces, author developed new field prediction model for spaces....
Liquid nitrogen has excellent ability of cooling and asphyxiating, which is suitable for fire extinguishing in urban underground utility tunnel. In order to obtain the influence injection method on efficiency, a medium-sized square tunnel was built. Fire experiments with different liquid methods distances were carried out. The distribution decrease law oxygen volume fraction temperature are analyzed. result shows that time extinguish enter controllable stage greatly reduced under both...
Casting performance is seriously jeopardized by metallurgical defects, especially the long-neglected bifilm defects that have been found in various alloys. The theory of entrainment formation has commonly accepted, but their visualization process and fracture behavior are absent to date, which explored present work. vivid numerical simulation results showed rapid rise liquid level leads violent melt fluctuation, repeated folding-entrainment-detachment oxide film on surface. Different motion...
Summary Experimental methods and theoretical analysis are employed to investigate effects of channel opening area on downward flame spread characteristics extruded polystyrene (XPS) thermal insulation materials building facade. The average height first drops then rises as dimensionless (the ratio sidewall area, ie, S * ) increases. As rises, both the maximum temperature curtain wall decrease, decreasing is linear. XPS surface history can be divided into four stages, inapparent rising stage...
