## Happenings – 2013 Mar 9

School continues, online of course.

I have finished a second course, Image and video processing…. As usual, I’ve done what I had to, not all that I wanted to. Anyway, I’m down to two active classes. (Never again will I try 4 at once. And I’m not even thinking about the next course I’ll start yet.)

This leaves Control of Mobile Robots – where the major challenge is that we can only take each quiz twice, but I was doing OK… and Digital Signal Processing, where I have fallen quite a bit behind. For the controls course, my next quiz is due next Sunday evening. For the signals course, on the other hand, quiz 3 is due before I go to bed tomorrow. OTOH, I can take each quiz 100 times.

And this is the weekend I really ought to get all my tax stuff together for my tax man.

As for the rest of the world, I’ve noticed that physicists are not ready to declare that they have found the Higgs particle… the Pittsburgh Steelers have released James Harrison.

are posed important aspects here where however must exposed main situations observed prof dr mircea orasanu and prof dr mircea orasanu and prof drd horia orasanu and so followed thatwith respect to time: v(t) = x’ (t) or v(t) = y’ (t), depending on the direction of motion. Velocity, by definition, is the instantaneous rate of change of position w/ resp. to time, hence the derivative. On a position vs. time graph, the slope of the tangent line corresponds to velocity and the steepness corresponds to speed. A velocity vs. time graph is a graphical mapping of all slopes on a position vs. time graph. The SI unit for velocity is the meter per second, m/s.
• Average velocity is displacement divided by time, while average speed is distance divided by time. Speed is always positive or zero, but average velocity can be positive, negative, or zero. Average velocity only depends on initial and final positions, along with the time interval between them; it is independent of the motion in between. In the example above, if the motion lasted for 10 s, the average velocity would be (+1 ft) / (10 s) = +0.1 ft/s, but the average speed would be (15 ft) / (10 s) = 1.5 ft/s. Note: average velocity is not simply the average of the initial and final velocities. This would only be the case if acceleration is a constant.
26. Come up with a nonnumerical scenario that clearly shows that average velocity is not this simple average.
• Acceleration is the rate at which velocity is changing w/ resp. to time. That is, a(t) = v’(t) = x’’(t). Like velocity, acceleration can be positive, negative, or zero. We can say, “Acceleration is to velocity as velocity is to position.” In common language, deceleration refers to slowing down, but a negative acceleration could correspond to speeding up. It all de pas observed prof dr mircea orasanu and prof horia orasanu here appear as followed
LAGRANGIAN AND LEBESGUE THEOREM
ABSTRACT
Oh, sure. So according to modern probability theory, which is based on measure theory, the probability of picking a random real number in [0,1] and getting a computable one is zero. Yet no measure theorist can give us even one example of a single uncomputable real number.hus here we observed that here prof dr mircea orasanu and prof horia orasanu appear some situations as followed
LAGRANGIAN OPERATORS AND LEBESGUE THEOREM
ABSTRACT
In considering the future of teacher education at the present time, I believe that it is relevant to consider the wider social and political context in which schools and institutions of teacher education are placed at this time. In particular I wish to draw attention to what Prime Minister Tony Blair had to say in his speech to the 1998 Labour Party Conference, where he argued that:

in our days the question of school is a problem very important observed prof dr mircea orasanu and prof drd noria orasanu and followed that these must obliged to solve as least in parts with the above aspects
