Page recognition search engine duty is not a gift

April 13, 2010, in Baidu Bar Webmaster Club, well-known Chinese SEO expert Zac in the "generation of original content can not be identified" post asked: "Their original content ranking is often more than reprint or plagiarism, webmaster can do what to prevent or improve?" My station updates original content every day, And Baidu is updated every day, but the other people's reprint is included, my article on the search is not. I persisted for nearly 4 months original, but Baidu still threw me to m

About 22.5KHZ analog pulse signal (60V) duty ratio test, duty ratio accuracy 0.1%

Two methods:1, collect the signal complete waveform, carries on the calculation:Is it possible to select an analog capture card with a 250ks/s sampling rate to display the required waveform?No! We have not considered measuring accuracy 0.1%!Because the analog signal is continuous, the period of the signal is 1/(22.5K) =44.4us, duty cycle accuracy of 0.1%, the signal resolution of at least 44.4us/1000=44.4ns, the sampling rate than 1/44.4ns=22.5ms/ s t

Design Pattern Learning Notes (19)-chain of responsibility duty chain pattern

course, it is possible to the end of the object chain, there is no object to handle the request. I think this is If...else if...else with our usual writing. The functionality to be done is too similar. The above is only a case of chain of responsibility, some books called it the Pure duty chain mode (I can deal with it, can not deal with the other people to deal with), there is another case is not pure duty

Description have T (1≤t≤10^6) time of day. John is going to arrange for his N (1≤n≤25000) cows to come on duty and clean the barn. Each cow has its own free time period [Si,ei] (1≤si≤ei≤t), only the idle cows can be arranged out on duty.Also, a cow must be on duty every time period. So how many cows do you need to take on duty at least? If there is no way to arra

Describes how to calculate the PWM output and frequency and pulse width (duty cycle) of stm32-six-step register Configuration

I. the PWM output pin of stm32 is the reuse function of the I/O port. Ii. T2 ~ T5 these 4 Universal timers can output 4-way PWM--CH1 ~ . 3. We will use tim3's PWM output as an example to explain the text (other similar ), finally, we will provide the C code output by the two PWM methods of tim3 and CH2 (the test has been successful on stm32f103rbt6, so you can use it with confidence !). 4. The formula for calculating the PWM frequency and duty cycle i

6 design Principles (1): Single duty principle

Definition: You should and only have one reason to change the class.Understand:If a class takes on too much responsibility, it is tantamount to coupling these responsibilities, and a change in responsibility may weaken or inhibit the ability of this class to perform other duties,This coupling can lead to fragile designs. When the change occurs, the design suffers unexpected damage.If a class A, there are two responsibilities, a, a, when responsibility a due to changes in requirements and needs t
