This paper proposes a Negative-buoyancy Quad Tilt-rotor Autonomous Underwater Vehicle (NQTAUV), for which an attitude-tracking controller is designed for the hover and transition modes based on a disturbance-rejection control scheme.First, the structure of NQTAUV is illustrated, a mathematical model based Ski de fond - Accessoires - Fixations - Ska
In order to initiate the design process for a new aeroengine, it would be necessary that a matching study be performed between the aircraft under design and its prospective power plant.In this work wing loading and engine thrust reqiurements are determined.Within this context thrust level is determined for a fighter jet whose mission profile is pre
First of all - about the connections of culture and religion.This question is one of those who, in the recent Eyeshadow Stick past, was subjected to all kinds of distortions.Consequently, our contemporary Ukrainian society needs a true meeting of religion and culture.The attempt of Marxism to create a new humanism, which completely rejects religion
This paper presents a compact circularly polarized (CP) Turntable Stylus Cleaning Brush antenna with an integrated higher order harmonic rejection filter.The proposed design operates within the ISM band of 2.32 GHz- 2.63 GHz and is suitable for example for wireless power transfer applications.Asymmetrical truncated edges on a square ring create a d
