In the use of Dedecms 5.7sp1 found that there is a bug that cannot modify the frequency of the keyword. Keyword can not be modified after adding frequency. The following is Dedecms 5.7SP1 cannot modify the keyword frequency bug fix method: 1. Open dedetempletsarticle_keywords_main.htm and find the following code: The code is a

Video memory bit wide memory to show the channel of the chip, determine the existence of an operational cycle of instantaneous throughput; Insufficient bit width will cause high resolution screen is not fluent, or frame number instability, because the graphics chip is not sufficient Data to compute. Basically 128 bit can cope with the high resolution of the mainstream. 2. Memory bandwidth memory and video card chip between the amount of data transfer Its size is determined by the bit w

The high and low frequency method of grinding skin has become popular abroad. This method breaks down the shape and color of the image into two layers of high frequency and low frequency, which can not only be adjusted separately but also not interfere with each other. Low-frequency layer can be used to adjust the col

The RTP timestamp is calculated at clock rate to represent the time. RTP timestamp represents the time per frame, since one frame (such as I-frame) may be divided into multiple RTP packets, so that multiple RTP timestamp of the same frame are equal. (The frame can be distinguished by the last RTP marker flag per frame, but the most reliable method is to view the same RTP timestamp package as the same frame.) ） Increment of RTP timestamp between two frames = clock

of references (citations) (ii) Methods for calculating the JCR indices Four indices, such as "Impact Factor", "Immediacy Index", "cited Half life" and "citing half", are defined in JCR, and the following calculations are based on the 1996 science Magazine as an example to explain the calculation methods of various indices. Brief introduction of periodical partitioning method: The influential factors of sci-tech periodicals (if,impact Factor) and the total cited

Ibus database high-frequency keyword Error Correction script-general Linux technology-Linux technology and application information, the following is a detailed description. After using ibus for a long time, I often suddenly find that some of the original preference or commonly used words suddenly fall behind, or even to the second page, it is not squeezed out by other words, however, the ibus user database may be out of order. I don't know whether th

By default, the Windows 7 system Synchronizes time automatically once a week. For those who have strict requirements on time, the frequency is too low. In this regard, the author provides two methods to adjust the time synchronization frequency of Windows7 system. Under www.2cto.com by default, Windows 7 automatically synchronizes time every week. For those who have strict requirements on time, the

Article Title: CPU frequency adjustment in linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. There are third-party CPU frequency adjustment software developed by Windows. In fact, there have been related software in linux for a long time. The default CPU operation

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 domain to the frequency domain. In this way, the characteristic

Label: blog HTTP using Java file SP Div 2014 C 1. before doing this project, I had worked on some projects in the OO class, and I was very familiar with this algorithm. Therefore, I learned the simple lexical algorithm and file operations in the C # language, it is expected to be written in one day.2. In fact, I found that C # is a little different from Java I have learned before. The algorithm is very simple, but it took a lot of time to learn to use C #. It took two days to complete the proce

After a piece of work, I decided to play with the super-frequency. I took a layer-2 bf531 board and tried to overtake it. from 400 to 600 m, the chip was running stably, I hit it with an infrared, and kept the temperature below 36 degrees. Well, I think of the famous saying of our hardware buddy who used the Beidou system. The high level of layout is to deploy the Six-layer layout on two layers and ensure stability! ***********************************

Four types of circuit configurations:Transistors are nonlinear components, when two different frequencies are added to the non-linear element, will produce a large number of new frequency signal, including two signal frequency difference, and, as well as its harmonic difference, and.For example, I do the mixing need to get 10.7MHz, because the received RF signal frequen
