“…In the case of unmanned aerial systems, for example, it is crucial to model the co-evolution among multiple features in time series. To tackle this challenge, Ma et al 6 proposed a novel approach that integrates Bayesian networks and normalizing flows. They developed graphical normalizing flows (GNF), a graphbased autoregressive deep learning model that performs anomaly detection in multivariate time series through density estimation.…”

“…Security/Privacy Vehicle Safety and Fault Detection (GNF) models can be utilized for anomaly detection in UV swarms [120]. GNF leverages Bayesian networks to identify relationships among time series components and perform density estimation in the low-density regions of a distribution where anomalies typically occur.…”

offer civil engineering courses to undergraduate and graduate students. This paper discusses and compares Civil Engineering curriculum in both Universities. The Civil Engineering courses at the University of Florida are divided into two phases of general education and upper division/civil engineering core education. At Nanyang Technology University, the Civil Engineering offers courses of a prescribed core of essential subjects and both institutions offer excellent program of study. The Civil Engineering program at Nanyang Technology University offers courses closely related to industry and government needs. Similarly, at the University of Florida, Civil Engineering program also offers excellent education program in line with government and industries needs. At both institutions, efforts should be focused on revising curriculum that is more responsible to existing and future rapid technological changes.
