High efficiency and low fuel consumption make the contrarotating open rotor (CROR) system a viable economic and environmentally friendly powerplant for future aircraft.While the potential benefits are well accepted, concerns still exist with respect to the vibrations and noise caused by the aerodynamic interactions of CROR systems.In this paper, em
Conclusions: Moist desquamations are more likely to occur in severe radiodermatitis in patients with head and neck cancer.Since they can fuse and spread, preventative measures to mitigate spreading are Mens Sweaters important.However, there is insufficient information to examine the causes of widespread moist desquamations.For preventing moist desq
Septum polarizers have been used in waveguide systems for over 50 years and are very popular in communication satellites operating in circular polarization.With the progress of computational electromagnetics and computer hardware, combined with advances in manufacturing techniques, there has been a growing interest in septum polarizers with smooth
Background Heat-altered stones (HAS) are commonly reported in prehistoric sites across several continents, yet they continue to be generally overlooked and systematic studies on them are scarce.Methods We performed a systematic literature review which consisted of searching journal articles, book chapters and books published in English, in Scopus a
Major challenges for automatic ship detection in optical remote sensing (ORS) images include cloud, wave, island, wake clutters, and even the high variability of targets.This paper presents a practical ship detection scheme Door Mats to resolve these existing issues.The scheme contains two main coarse-to-fine stages: prescreening and discrimination
