Voting doesnot work by two domain name both domain names direct to the pligg site at the same time: the voting script cannot work (Cross Domain problem ?) I have two domain names pointing to the same site.I have two names refer to the same site. They are:As:Http://clin003.c

Recently, in digital image processing, I did not have an intuitive concept in the time domain and frequency domain. I will search for it and summarize it as follows:1. The simplest explanation The frequency domain is the frequency domain, We usually use the

spectrum smooth, on the other hand, due to the data truncation caused by the frequency domain leakage, there may be some difficult to confirm the spectral peaks in the spectrum (see "Digital signal Processing" Textbook 147 page Figure 6-13), After 0, it is possible to eliminate this phenomenon. FFT complement 0: The spectral resolution of the N-point DfT is 2π/N. The Fence effect section indicates that more frequency points can be observed by filli

I am so ashamed to learn "digital signal processing" for a long time. I also remembered the Fourier transformation formula and made the FFT program, but I don't know what the significance of Fourier transformation is! That's it !! Fortunately, I understand it. Aside from the mathematical meaning, let alone some practical meanings. Fourier transform is used to convert signals from the time

recently, found that the company domain member user time and the domain server time is not synchronized, to achieve: 1, the domain member server and intra-domain client and domain NTP s

Company attendance is an OA software in the domestic attendance module, the personal computer in the specified time in the form of registration, the client is to take the form of domain user login, the computer client time display than the time of OA registration two minutes later, [Note: The OA server installed

The verification fails if the time difference between the client and the domain controller is more than five minutes. the user name and password are correct even if the domain member relationship is correct.You do not need to modify the time to avoid permission verification failures when using resources in the

ArticleDirectory STEP/Method Many webmasters try their best to find a satisfactory domain name, especially when they find that their desired domain name is about to expire, and they do not know when to register again. The following describes how long can I query the domain name expiration time on a registr

can handle only one event, that is, we will have two event handler to handle the corresponding event respectively. Because domain aggregate is a one-time atom, it generates two domain event at once. So, we want to make sure that two event handler either update successfully, or not update the success, this problem has not been considered before, let's think of wa
