The alpha roll is a dog training technique that is considered outdated by many modern-day dog trainers. The theory behind the training method is that dogs are hierarchical animals. The technique is used to teach the dog that the trainer or owner of the dog is the pack leader (alpha animal). Methods include when a dog misbehaves to pin the dog ...
The roll motion is characterized by an absence of natural stability, there are no stability derivatives which generate moments in response to the inertial roll angle. A roll disturbance induces a roll rate which is only canceled by pilot or autopilot intervention. This takes place with insignificant changes in sideslip or yaw rate, so the ...
The organization of this article is basically random with weasel words and dubious claims peppered throughout. I'm going to try and do a rewrite of this page with better organization, a true representation of what has been written in literature (on BOTH sides), and a stricter use of reliable sources.
The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system. [1]They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in three dimensional linear algebra.
The term alpha was popularised as early as 1976 in the dog training book How to Be Your Dog's Best Friend (Monks of New Skete), which introduced the idea of the alpha roll, a technique for punishing unwanted dog behaviours.
The equilibrium roll angle is known as wings level or zero bank angle, equivalent to a level heeling angle on a ship. Yaw is known as "heading". Yaw is known as "heading". A fixed-wing aircraft increases or decreases the lift generated by the wings when it pitches nose up or down by increasing or decreasing the angle of attack (AOA).
The raised-cosine filter is a filter frequently used for pulse-shaping in digital modulation due to its ability to minimise intersymbol interference (ISI). Its name stems from the fact that the non-zero portion of the frequency spectrum of its simplest form (=) is a cosine function, 'raised' up to sit above the (horizontal) axis.
"X" or "x" axis runs from back to front along the body, called the Roll Axis. "Y" or "y" axis runs left to right along the wing, called the Pitch Axis. "Z" or "z" runs from top to bottom, called the Yaw Axis. Two slightly different alignments of these axes are used depending on the situation: "body-fixed axes", and "stability axes".
