This research studies the spatial distribution quality of spatial interpolation methods.The research aims first to obtain unbiased estimator parameters based on regionalized variables in the study field.We used kriging techniques (called Local spatial interpolation) to rely on the variogram function with a fuzzy inference system, where fuzzy krigin

Flight conflict detection is fundamental to flight dispatch, trajectory planning, and Hard Drive flight safety control.An ever-increasing aircraft population and higher speeds, particularly the emergence of hypersonic/supersonic aircrafts, are challenging the timeliness and accuracy of flight conflict detection.Traditional trajectory conflict detec

In this paper, a new approach is proposed to predict the far-field noise of a landing gear (LG) based on near-field flow data obtained from multiple two-dimensional (2D) simulations.The LG consists of many bluff bodies with various shapes and sizes.The analysis begins with dividing the LG structure into multiple 2D cross-sections (C-Ss) representin

In vehicular ad Black Boyfriend Jean hoc networks, attackers can disguise as replicas of legitimate vehicles by cracking or colluding and then use the identity replicas in a malicious way.Not only the generation of replicas itself poses an aggressive behavior, but also the replicas can enable other insider attacks, such as denial of service, inform
