The behaviour of the controllable pitch propeller actuating mechanism is considered in terms of blade position, oil pressures inside the controllable pitch propeller hub and magnitudes of the forces acting on the blades. In the proposed mathematical model, the forces acting on the propeller blade are...
This method is introduced by using 2D+t theory and employs potential field related to hydrodynamic impact of an asymmetric wedge with roll speed to solve four relations for the involved added masses in the motion. Momentum variation of the derived added mass terms is used to compute 2D normal ...
Comparison in terms of pitch shifting is presented here. Analysis was performed for a single frame and a full segmentation of speech.doi:10.2478/v10187-010-0008-5MousaAllamVersitaJournal of Electrical EngineeringAllum Mousa,"Voice Conversion Using Pitch shifting algorithm by time stretching with ...
In principle, though, any practical sample rate and number of audio channels are supported. Request::position is a timestamp, it defines the grain centre point in terms of an input audio frame offset. It is the primary control for speed adjustments and is also the driver for seek and ...
This thesis reports on an investigation into the simulation of ship manoeuvring in restricted waters; in particular ship squat and ship-bank interaction.A time-domain mathematical model has been developed to predict unsteady squat and dy... J Duffy 被引量: 5发表: 2008年 Mixing Flow Characteristic...
This fact gives short pitch cholesterics very unusual properties for their optical activity, which is related to the scaling terms as (p/0)m, with m odd and greater than 1. Some problems related to the presence of these terms and concerning boundary effects are discussed but not fully ...
That’s the amount of time the catcher has from the moment the ball hits her glove to the moment it must be at second base to catch that runner: 2.6 seconds, aka her “pop” time. Notice that nowhere in that simple mathematical formula does it say anything about how the ball is throw...
In general, pitch is the term for how “high” or “low” the note sounds, and it can be measured and written in terms of Hertz or notation on a musical staff. There are a lot of terms and numbers in this post, so it could be worth going over a few times to make sure everythi...
The mathematical relationship of pitch diameter, diametric pitch, and number of teeth is shown in the equations below. As with any equation, one of the variables can be calculated if any two are known. P=NDD=NPN=D×P where: D = Pitch diameter, inches P = Diametric pitch, inches N =...
rotation. Since the camera is virtual, the Euler angle singularity is just a mathematical issue, not a physical one. It will only cause problems when doing things like linear interpolation of Euler angles near the singularity (we currently do linear interpolation of Euler angles ineaseTo()and...
