time (Fig. 3, fig. 6) Where the temperature anomaly occurs by varying the amplitude of each modal. In this case, the modal 5 amplitude change is small and the modal 4 amplitude changes greatly, which indicates that the temperature anomaly mainly occurs in the time scale of 35 days, and the anomalous time is mainly concentrated in 2009 1 to March. In addition, the software program can output a time-varying spectrum based on the "direct interpolation method" (Fig 5), it is more intuitive and more

transform the x[n] again, such as: X[n] = (Re x[k] + j Im x[k]) (cos (2πkn/n) + j sin (2πkn/n)) = (Re x[k] cos (2πkn/n) + j Im x[k] cos (2πkn/n) + J Re X[k] sin (2πkn/n)-Im x[k] sin (2πkn/n)) = (Re x[k] (cos (2πkn/n) + j sin (2πkn/n)) +--------------------- (1) Im x[k] (-sin (2πkn/n) + j cos (2πkn/n)) nbs P ---------------(2) then we split the original equation into two parts, the first part is multiplied by the spectrum in the real domain, and the second part is multiplied by the spectrum i

(2πkn/n)) Now we're going to analyze this equation, and we'll see that this formula actually has the same result as the real Fourier transform. Let's change the x[k] a bit first: X[k] = Re X[k] + j Im X[k] This allows us to transform the x[n] again, such as: X[n] = (Re x[k] + j Im x[k]) (cos (2πkn/n) + j sin (2πkn/n)) = (Re x[k] cos (2πkn/n) + j Im x[k] cos (2πkn/n) +j Re x[k] sin (2πkn/n)-Im x[k] sin (2πkn/n)) = (Re x[k] (cos (2πkn/n) + j sin (2πkn/n)) +---------------------(1) Im x[k] (-sin (

A single problem with the Linux sound system: I beg you to read the Linux general technology-Linux technology and application information, which is not only a microphone but also a recording software. Some time ago, I searched the screen recording software in Linux and found that some of them could only record microphones. If I put a piece of music, the video would not be recorded, later, I wanted to use a recorder to record the background sound, but I could only record the microphone. The same

period, there was something worth noting. That is GNOME. Specifically, it is GNOME 3. In essence, GNOME 3 is similar to Unity. GNOME developers decided to do their best to put the desktop on hand. Unity developers tried to integrate (ended in failure), but GNOME developers did some really important work. That is, they helped build a perfect Linux Desktop release. That's Ubuntu GNOME 15.10. It is what Ubuntu initially wanted to be. It is what every Linux desktop environment should do. In fact, s

Listen to my nonsense so much, I think I have to return to the topic, I write this article is what the reason is, in fact, and the above these nonsense have relations, it is like, you xxoo time to have foreplay (this? a bit too direct), Or you might want to put some whole grains on the outside before you 屙 excrement (it sounds like you're cursing at me). But these examples are indisputable facts, so you should not l

I totally agree that money is a game currency, but I still don't know what my talent is.I had the audacity to ask my parents, relatives and friends, the answers were varied, but none of them said I was suitable for business, and it was strange that my mother said I was suitable for writing novels.

optimization, I am afraid that only we will do so.R.U.B.E : For our next game, we've developed an in-game editor almost ourselves before using R.U.B.E (Really useful box2d editor), a very powerful tool that saves us a lot of time, but if we decide to do a level editor, We have to develop it ourselves.
