A Petri-net approach for firefighting force allocation analysis of fire emergency response with backups

Zhou, Jianfeng (author), Reniers, G.L.L.M.E. (author), Cozzani, Valerio (author)

Fire is one of the main accident scenarios occurring in chemical and process plants, and it can lead to domino effects due to thermal radiation. Emergency response is necessary to prevent fire escalation, in addition to safety barriers. In major industrial fire accidents, backup is usually required in emergency response, due to the lack of...

Secure genotype imputation using homomorphic encryption

Zhou, Junwei (author), Lei, Botian (author), Lang, Huile (author), Panaousis, Emmanouil (author), Liang, K. (author), Xiang, Jianwen (author)

Genotype imputation estimates missing genotypes from the haplotype or genotype reference panel in individual genetic sequences, which boosts the potential of genome-wide association and is essential in genetic data analysis. However, the genetic sequences involve people's privacy, confirming an individual's identification and even disease...

Experimental and numerical study of Conoscopic Interferometry sensitivity for optimal acoustic pulse detection in ultrafast acoustics

Robin, M.P. (author), Guis, R.H. (author), Arabul, Mustafa Umit (author), Zhou, Zili (author), Pandey, Nitesh (author), Verbiest, G.J. (author)

Conoscopic interferometry is a promising detection technique for ultrafast acoustics. By focusing a probe beam through a birefringent crystal before passing it through a polarizer, conoscopic interferences sculpt the spatial profile of the beam. The use of these patterns for acoustic wave detection revealed a higher detection sensitivity over...

Ship behavior during encounters in ports and waterways based on AIS data: From theoretical definitions to empirical findings

Zhou, Y. (author), Daamen, W. (author), Vellinga, T. (author), Hoogendoorn, S.P. (author)

Currently, the research on ship behavior during encounters focuses on evasive behavior during specific situations with existing risks of collision. However, the preliminary selection of encounters to refine the presented ship behavior is biased. To obtain a full understanding of all ship behavior during different encounters in ports and...
