A virtual flight test is the process of flying an aircraft model inside a wind tunnel in a manner that replicates free-flight.In this paper, a 3-DOF aircraft-manipulator system is proposed that can be used for longitudinal dynamics virtual flight tests.The system consists of a two rotational degrees-of-freedom manipulator arm with an aircraft wind
Recent experimental data has demonstrated significant influences of graphite volume concentration on the dielectric breakdown and energy storage behavior of graphite-polymer composites, but no existing homogenization theory has been established to illustrate such dependence in the pycom expansion board 2.0 context of alternating current (AC) loadin
Gastroesophageal reflux disease is one of the most common gastrointestinal disorders which is mainly characterized by problems with esophageal peristalsis, which is responsible for propelling food from the esophagus into the stomach or dysfunctional or weaker lower esophageal sphincter, which prevents the reflux to stomach contents.Typical symptoms
Background.Roach, Rutilus rutilus, comprise a large proportion of the total catch in the Szczecin Lagoon, and are caught mainly as bycatch in gillnets targeting perch, Perca fluviatilis.The minimum landing length for roach and perch is 17 cm TL and the minimum mesh size is 30 mm bar length.However, little is known about the selectivity of roach, wh
