MODEL OF A MATRIX CROSSCORRELATION FUNCTION OF THE PROBING AND REFLECTED VECTOR SIGNALS FOR A CONCEPTUAL DESIGN OF A SYNTHETIC APERTURE RADAR ON AN AERIAL CARRIER by R. N. Akinshin, O. V. Esikov, D. A. Zatuchny, A. V. Peteshov

“…The scheme is invariant with respect to the type of an air carrier with a synthetic aperture radar: an aircraft, a helicopter, an unmanned aerial vehicle and similar ones: an air carrier "enters" it by only an automatic control system, a model of trajectory instabilities and a spectrum of frequencies of elastic oscillations of its design. …”

A coupled finite volume and material point method for two-phase simulation of liquid–sediment and gas–sediment flows by Baumgarten, Aaron S, Couchman, Benjamin LS, Kamrin, Ken

“…Mixtures of fluids and granular sediments play an important role in many industrial, geotechnical, and aerospace engineering problems, from waste management and transportation (liquid–sediment mixtures) to dust kick-up below helicopter rotors (gas–sediment mixtures). These mixed flows often involve bulk motion of hundreds of billions of individual sediment particles and can contain both highly turbulent regions and static, non-flowing regions. …”

An analysis of commercially recommended profiles for normobaric preacclimatization by Markus Tannheimer, Raimund Lechner

“…Our regimen induced sufficient acclimatization to Manaslu Base Camp (4900 m), as evidenced by the fact that none of the expedition members suffered from AMS although they reached base camp within 2 days from Kathmandu – by helicopter flight to 3500 m and a one day walk the next day. …”

As condutas políticas dos ritornelos musicais by RODRIGO CARQUEJA MENEZES

“…To do so, we use the concept of ritornelo as a "theme" to show how, from a small territorial ritornelo (folk song, baby song, Vienna waltz, lullaby, cow bells, helicopter noise, for example), the becoming-music produces a great deterritorialized ritornelo and brings molecular materials to the surface, making us listen to so far inaudible forces. …”
