The research has been done yesterday, but due to the patent application, there has been no time to upload, today to fill.Today, mainly using TIM3 PWM input mode, the width of the pulse signal of the rectangular wave and its period of measurement, first look at a picture. Figure 1 Tim Internal logic diagramLet's take a look at what the datasheet says:This mode is a special case of the input capture mode, except for the following differences, the operat

case: A similar article is recommended when reading an article.This case is simple and rough, especially when I read the novel, when the book shortage, really want to have such a function. (PS: I work for a fiction company now)So , how do you measure the similarity between articles?Before you start, talk about Elasticsearch.The index used by Elasticsearch is called an inverted index. Split the document into one word and then record where the word appe

1 Information Entropy The amount of information in a message has a direct relationship with its uncertainty. The amount of information is equal to the number of uncertainties. How to quantify the measurement of information. The information entropy (entropy) is denoted by the symbol H, which is the unit bit. The greater the uncertainty of the variable, the greater the entropy. If a book repeats a lot of co

[Preface] In the information security risk management field, there are three requirements or problems: • Enterprise top management needs to see the overall situation of enterprise information security risks from a macro perspective • The measurement methods of information security risk are not objective enough. The existing measurement methods contain too many subjective factors, making the

When talking about routing protocols and routers, administrative distance (administrative distance) and measurement (Metrics) are two important parameters. What do these two sets of parameters really mean? David Davis will introduce the two sets of parameters and explain the reasons why Cisco routers need to understand the importance of management parameters. When it comes to the routing protocol and the channel used by the router, Management Distance

First, the view drawing process frameworkThe drawing of the view is iterated from the top down. Decorview-->viewgroup (--->viewgroup)-->view, follow this process from top to bottom, measure (measurement), layout, Draw (draw).Second, measure processAs the name implies, the size of each control is measured.Call the measure () method, do some logical processing, and then call the Onmeasure () method, where you call Setmeasureddimension () to set the view

Testin Cloud measurement and arm strategic cooperation: driving global mobile applications to accelerate access to the Chinese market 2014/10/14Testin·Industry News(Beijing, China – October 14, 2014) the world's largest mobile gaming, application real and user cloud test platform Testin today announced the establishment of a strategic partnership with ARM to establish an "Arm application Testing Center". The center is designed to help global developer

The algorithm of the image measurement system includes the extraction of geometric features (points, lines, circles, ellipses, curves, slots, etc.), software interaction, camera calibration algorithms, etc. Note: It is a measurement system-related technology, not a specific measurement project. Note: Limited to university research team, experienced software engin

The Vegeta provides a stable QPS pressure source, and Boom provides a stable number of concurrent pressure sources.GitHub Address Https://github.com/ireaderlab/alex中文版 Alex Frame Composition Alex Main Features Save pressure test parameters for repeated pressure measurement Save stre

It is very helpful to know about vro parameter settings. Here we mainly introduce the parameter settings for management spacing, including the measurement of vro. When talking about the routing protocol and router parameter settings, the administrative distance (administrative distance) and measurement (Metrics) are two important parameters. What do these two sets of parameters really mean? David Davis will

Openlayers learning the best way is to follow its own example to learn, in addition to the Web front-end development and design to understand, and slowly accumulate, so in general small projects should be enough. The Reference measurement demo implementation of the format of the dialog box measurement, the use of this function, the following query, positioning, etc. based on the form of dialog box is easy t

It simplifies the entire development cycle of the software and shortens development time. Measurement rapid development Platform is the leading SOA application development platform,

broadband speed measurement method is a different speed, We do not know where the location of the server where the speed is used (may be very far), different from the time, location, the introduction of line loss and other factors, test results will be very different, then how to accurately test their use of broadband speed it?It is recommended to use the peer download software, (such as thunder, Electric Donkey) broadband speed ! As much as possible

People are very concerned about the speed of download, for users of non-monthly broadband and use of paid CDN, this is a typical take money to buy time behavior, I pay the higher the cost, the faster you want to download, the greater the cumulative bandwidth used. About a variety of speed measurement method is also voluminous, this paper introduces the speed of TCP transmission.Overview of TCP Rates first, the TCP rate is affected by multiple delays,

Still struggling to find a suitable wire record table, Old Wang shared his frequently used record table, let you one step in place, not to worry about the measurement results table that conforms to the closed full circle method wire record table calculation table, I put the corresponding images and brief descriptions in my measurement space. For your use. 1. Wire record table 1 (applicable to conforming wir

quality.One thing is certain, we can not directly measure the quality of the software, we can only be measured by some specific quality characteristics of the software. Then we set the standard for these quality characteristics, so we built up the concrete quality measure standard. The standard of quality measurement can also be called the quality model, which is the core part of the quality management process. Two kinds of commonly used quality
