Broadband Access Network is currently the most common access method, so I have studied the design concepts and standards of broadband access networks. I would like to share with you here, hoping to be useful to you. A Broadband Access Network is a transmission medium. It establishes multiple independent network carrier signals on a coaxial cable or fiber-optic cable through different channels. In general, a broadband access network also refers to a high-speed network connection. For example, a b

ADSL is not a new technology, but it has been in the recent period of rejuvenation of youth, not only in the international market has been more widely used, but also by the attention of domestic operators, began to scale the network and put into commercial. China Telecom, China Unicom, Chinese railcom and so on have invested funds to build ADSL networks in varying degrees. At the same time, the relevant DSL technology, including VDSL, HDSL and other t

vector and the x and Y axes. Calculating these angles is easier than you think, and now that we've calculated the RX,RY,RZ values, let's go back to our previous acceleration model and add some more annotations:2012-8-22 16:38 UploadDownload Attachments(9.9 KB) The angle we are interested in is the angle between the vector R and the x, Y, Z axis, which is AXR,AYR,AZR. Observe the right triangle consisting of R and Rx:cos (AXR) = rx/r, similar to:cos (Ayr) = ry/rcos (AZR) = rz/rFrom Equation 1 We

The previous section describes spiral tubes and conch tubes. likewise, shells have a spiral. this section provides several algorithms for generating conch and shells. when it comes to conch, it reminds me that my university is on the beach. When I leave the east campus, it is the sea, and even the school dormitory is a sea view room. I also like conch and shells. After all, their meat is delicious.

If $ {X _ {n + 1 }}=\ cos {x_n} $, prove that $ \ mathop {\ lim} \ limits _ {n \ To \ infty} {x_n} $ exists. Note 1:As we want to prove that a limit of sequence exist, some methods can be used. $ \ Left \{{ x_n }}\ right \}$ is bounded and monotonic, then $ \ left \{{ x_n }}\ right \}$ converges. $ \ Left \{{ x_n }}\ right \}$ converges if and only if $ \ left \{{{ X _ {2n }}\ right \}$ and $ \ left \{{ X _ {2n + 1 }}\ right \}$ Both converge to t

We have discussed n leaf knots. When n is greater, you will find that the image is more like a ring. This section describes several other curves wound around the ring. vertices = 12000t = from 0 to (64*PI)p = rand_int2(2, 32)q = rand_int2(2, 32)r = 2 + cos(q/p*t)x = r*sin(t)y = sin(q/p*t)z = r*cos(t)r = 0.5 + 0.5*sin(t)g = 0.5 + 0.5*yb = 0.5 + 0.5*cos(t) Curve

it. Other cases can be proved similarly.Using the inverse proof method, we assume that all the edges of the smallest rectangle that covers the convex hull are not overlapped with the edges of the convex hull. That is to say, each edge of the smallest rectangle has only one vertex of the convex hull. As shown in 3, the rectangle ABCD is the smallest rectangle covering the convex hull. M, N, P, and q are the vertices of the convex hull on the four sides of the rectangle. Let's create mm 'CD, NN '

the average of the equivalent RGB VA Lues.The HSI definition of saturation is a measure of a color ' s purity/grayness. Purer colors has a saturation value closer to 1, while grayer colors has a saturation value closer to 0. (In other color models, the meanings and mathematical definitions of "saturation" is slightly different. See HSL and HSV color models for comparison.)Equations to Convert RGB values to HSI valuesSuppose R, G, and B are the red, green, and blue values of a color. The HSI int

, and the average radius is 6371.004 km. If we assume that the Earth is a perfect sphere, its radius is the mean radius of the Earth, which is recorded as R. If the zero-degree longitude line is used as the basis, the distance between the two points can be calculated based on the latitude and longitude of any two points on the Earth's surface. (here, the error caused by the calculation of the earth's surface topography is ignored, only theoretical estimates ). Set the longitude and latitude of t

1. Introduction to ADSL Although it is common to connect to a vro network, we sometimes need to use PPPoE to directly connect to the ADSL (or DSL) modem. Of course, you must first pay for the network operators of China Netcom or China Telecom to connect the lines. The "DSL" on the modem is on, which generally indicates that your line is smooth. You must have the username and password of your account. A sui

. 2. the semantics of each expression must be well defined so that users can create models that others understand. Tools can generate legal implementations from models, metadata captured from the model can be used to process tasks as expected, such as configuring servers. Languages that meet these standards are called domain-specific language (DSL) and should be modeled for those special domain concepts. DSL
