Recurring green Fuse Holder tides (also called Ulva prolifera) cause significant damage to marine ecosystems in the Yellow Sea of China, especially in the settlement region.The settlement region is a critical area for the natural decay and decomposition of green tides, which obviously has ecological consequences.Recent studies in relation to this t
Selecting an appropriate alternative among the feasible selection options is a difficult activity for decision makers.Because of the imprecise information and the complexity of decision problem, it is not easy to evaluate the attributes in terms of crisp numbers.To deal with the problem, neutrosophic numbers can be used during the decision process.
Subject and purpose.The wave field of an acoustic antenna in a uniform subsonic flow is theoretically investigated.Purpose of the work is to obtain an analytical dependence of the sound field on physical parameters.Method and methodology.The article presents the aperture method of theoretical calculation of wave field of the acoustic antenna, which
