Long range prediction exploits the principal that the memory span of a predictive filter increases when it samples the input signal at a lower rate. Within the context of a communication system that employs adaptive modulation and coding communication, this implies that by measuring the channel at a rate that is minimally twice the highest Doppler frequency rather than twice the data rate (the ...

Beam-like flexible structures are of interest in many fields engineering, particularly aeronautics, where wings frequently modelled and represented as such. Experimental modal analysis is commonly used to characterise the wing’s dynamical response. However, unlike other structure applications, no benchmark problems involving high-aspect-ratio have appeared open literature. To address this, this...

Thin-walled structures are of great interest because their use as lightweight components in aeronautical and aerospace engineering. The fabrication these by additive manufacturing (AM) often produces undesired warpage the thermal stresses induced process components’ reduced structural stiffness. objective this study is to analyze distortion several thin-walled fabricated Laser Powder Bed Fusion...

Abstract The sporadic E (Es) layer has been known to introduce long-range propagation of aeronautical very high frequency (VHF) navigation beyond the radio horizon and cause potential interference on system. This study utilizes a rate total electron content (TEC) index (ROTI) map with dense Global Navigation Satellite System (GNSS) observations for effective Es detection. daytime shows...
