Approximately two years ago I authored a paper entitled, “The Forensic Examination of Video Recordings” which discussed some of the more conventional forensic techniques for examining questioned analog videotapes regarding their originality and for possible evidence of tape alteration. This paper specifically addressed the various mechanical and electrical signal anomalies that occur when editi...

Digital twin technology can be used for disaster safety management of underground utility tunnels, which are social infrastructures. To verify its efficiency in an tunnel, it must implemented and monitored the real world. Therefore, state information about object position world, change upon movement, should correspondingly reflected digital model. Underground tunnels through closed circuit tele...

Current road safety detection and analysis tends to focus on hit-and-run accidents that have already occurred, while ignoring near-misses may pose a potential risk. A monitoring method for based the improved YOLOv7 of transformers is proposed in this work. First, backbone network using G3HN structure (gn Conv) with recursive gate convolution. Second, global attention mechanism (GAM) added probe...

Fire and smoke detection in today’s world is a must, especially clustered areas where quick response can prevent significant damages save lives. Early plays role preventing the fire from spreading by alerting emergency personnel. It may not be possible to install traditional detectors everywhere. As result, incorporating into existing closed circuit television (CCTV) systems various places prov...

Abstract Building a smart city demands the digital transformation of government working processes and procedures, including digitization online execution most administrative procedures. In practice, governance uses information technology to increase efficacy efficiency providing services public. The development cities raises concerns among residents about transparency in data collection use per...

This paper presents an innovative digital twin dam and watershed management platform, K-Twin SJ, that utilizes real-time data simulation models to support decision-making for flood response water resource management. The platform includes a GIS-based geospatial of the entire Sumjin river system in Korea, with high-precision topography facility information dams rivers (watershed area 4913 km2, l...
