It is equivalent to a wave file and does not require decoding. You can directly input a Power Amplifier for DA conversion. Because of the large bit rate and volume, in the DVD era, audio tracks are usually used in two-channel music discs. When the Blu-r

is better designed than other version control systems because git tracks and manages changes, not files.You will ask, what is the modification? For example, you add a row, this is a change, delete a row, is also a modification, change some characters, is also a modification, delete some and add some, is also a modification, even create a new file, also counted as a modification.Why is git managing changes, not files? We still do the experiment. The f

I knew that Jeff had trained neural networks to control the cars and I was curious to learn more about It. jeff kindly agreed to answer my questions and has recently given me permission to make them available online. I know for sure versions of you will find his notes very interesting. so here They are... Cheers Jeff! (Prior to re

the mean variance (MSE) between hidden factor vectors and audio predictions for the output of the co-filtering model. These vectors are first normalized according to the unit norm Standard. This is done to reduce the impact of song popularity (many of the hidden factor vector norms of the collaborative filtering model are often related to the popularity of songs). The discarding method (dropout) is used as the regularization method in dense layer.The dataset I'm using now is the 30-second-long

the spindle motor. The capacity of each disk is called the capacity of a single disk, and the capacity of a hard disk is the total capacity of all disks. Because of the low capacity of a single hard disk in the early days, there were a large number of disks, and some even had more than 10 disks. Modern hard disks generally had only a few disks. All disks in a hard disk are identical, otherwise the control part is too complicated. A series of one brand of disks generally use the same disk. A ser

sequentially formed into a cylinder ), the head of each cylinder starts from "0" from top to bottom. Number of cylinders = number of tracks on a diskSlice The disc has a straight line from the center of the circle to the surrounding area. Different magnetic channels are divided into multiple slice (ARC) areas. Each Arc area is called a slice, and each slice is 512 bytes in size. The operating system stores information on disks in units of sectors (se

available independently, but not limited to this ). The disk is rotated at a high speed at the speed of thousands to tens of thousands per minute, so that the head can read and write data at the specified position on the disk. Because the hard disk is a high-precision device and the dust is its enemy, it must be completely sealed. 2. Working Principle of the hard disk Hard Disks are logically divided into tracks, cylinders, and sectors.Each disk has
