It can also convert between arbitrary sample rates and resize video on the fly with a high quality polyphase filter. Anything found on the command line which cannot be interpreted as an option is considered to be an output url. Selecting which streams from which inputs will go into which output is either done automatically or with the -map option see the Stream selection chapter. To refer to input files in options, you must use their indices 0-based.

Thanks to Daniel Le Guern! You can research all those and achieve wonderful but complex results. My way of explaining things require just basic math.

I am a great believer in simplicity.

To Retest System Performance After Tuning

I think a system that is simple is easier to control and monitor, besides many embedded devices do not have the power and resources to implement complex algorithms requiring matrix calculations.

We'll use parameters of this device in our examples below. This unit is a good device to start with because it consists of 3 devices: Now that's a fancy name!

Nevertheless, behind the fancy name is a very useful combination device that we'll cover and explain in detail below.

When thinking about accelerometers it is often useful to image a box in shape of a cube with a ball inside it. You may imagine something else like a cookie or a donutbut I'll imagine a ball: If we take this box in a place with no gravitation fields or for that matter with no other fields that might affect the ball's position — the ball will simply float in the middle of the box.

You can imagine the box is in outer-space far-far away from any cosmic bodies, or if such a place is hard to find imagine at least a space craft orbiting around the planet where everything is in weightless state.

Imagine that each wall is pressure sensitive. We then measure the pressure force that the ball applies to the wall and output a value of -1g on the X axis. Please note that the accelerometer will actually detect a force that is directed in the opposite direction from the acceleration vector.

This force is often called Inertial Force or Fictitious Force.

One thing you should learn from this is that an accelerometer measures acceleration indirectly through a force that is applied to one of it's walls according to our model, it might be a spring or something else in real life accelerometers.

This force can be caused by the accelerationbut as we'll see in the next example it is not always caused by acceleration. If we take our model and put it on Earth the ball will fall on the Z- wall and will apply a force of 1g on the bottom wall, as shown in the picture below: In this case the box isn't moving but we still get a reading of -1g on the Z axis.

The pressure that the ball has applied on the wall was caused by a gravitation force. In theory it could be a different type of force — for example, if you imagine that our ball is metallic, placing a magnet next to the box could move the ball so it hits another wall.

This was said just to prove that in essence accelerometer measures force not acceleration. It just happens that acceleration causes an inertial force that is captured by the force detection mechanism of the accelerometer.OpenSCAD is a 2D/3D and solid modeling program which is based on a Functional programming language used to create models that are previewed on the screen, and rendered into 3D mesh which allows the model to be exported in a variety of 2D/3D file formats.

Jul 22,  · Homework Help: Rewriting in terms of another (Trigonometry) Jul 21, #1. Write tanx in terms of sinx, x is in Quadrant 4. tanx = -sinx/cosx (-sinx because sinx is negative in Q4) Ok from $$tan(x)= \frac{-sin(x)}{cos(x)}$$ try using a formula for $$sin^2(x)$$ (hint the one that involves 1 and [tex] cos^2(x) .
