The power ripple index of the DC/DC module is an important parameter. A clean power supply is a prerequisite for the stable operation of the digital circuit and an important guarantee for the parameters of the simulator. To determine the power quality, the Output Ripple of the DC/DC module must be measured. However, the ripple value measured by many people is usually hundreds of music videos or even hundreds of music videos, which is far greater than the maximum ripple value provided by the devi

Similarity measurement in machine learningWhen classifying, it is often necessary to estimate the similarity metric between different samples (similarity measurement), which is usually done by calculating the "distance" (Distance) between samples. The method used to calculate the distance is very fastidious, even related to the correct classification.The purpose of this paper is to make a summary of common

Recently the company wanted to do a PM2.5 testing equipment, probably studied the PM2.5 related knowledge, as well as sharp dn7c3a006 sensor applications.The following is a brief introduction to it.1, its own dust-free voltage (nodust_v), the nominal temperature (base_temp), the two values are scanned by a QR code, such as the scan we purchased to obtain the "149190104F 1.31 * * * * 25.8", can be obtained nodust_v = 1310mv, Base_temp = 25.8 ℃ (but these two values only serve a certain reference,

GeometryService of Arcgis for Js achieves measurement distance and area Common GIS functions for measuring distance and area. In this section, GeometryService is used to measure the area and distance. First, let's look at the effect after implementation: Distance Area First, configure: //identify proxy page to use if the toJson payload to the geometry service is greater than 2000 characters.//If this null or not available the project and lengths op

First, IntroductionThe Android system must measure the view before drawing the view, which tells the system how much view to draw. This process is performed in the Onmeasure () method. The Android system provides the Measurespec class by helping us measure the view.The measurement mode can be divided into three types: Exactly: that is the exact value mode, the system uses the exactly mode by default. At_most: The maximum mode, when the co

There are many IOS applications with measurement angles, but most of the applications are designed based on the actual measuring angle. In real life, it is inconvenient to use these software to measure the angle. On the other hand, in some professional fields, such as construction, machinery, sometimes some angles such as the two sides, tilt angle, these special angle measurements are not implemented in many applications. Here we recommend a 3D provis

What determines the MeasureSpec of a View during measurement ?, Viewmeasurespec We all know that to determine the View size, the system must first obtain MeasureSpec and then determine the View size through MeasureSpec. MeasureSpec (32 is an int value) consists of two parts: SpecMode (2-bit high): Measurement Mode. SpecSize (30-bit lower): The specification size in a certain

Used a lot of pressure measurement tools, but has not found the favorite. Recently tried wrk feel good, write down the use of the Guide to their own memo, if can help you, that is also very good.InstallationWRK supports most Unix-like systems and does not support Windows. Operating systems are required to support Luajit and OpenSSL, but don't worry, most Unix-like systems are supported. Installing the WRK is as simple as downloading the wrk source fro

It supports three measurement methods, distance, height, length, the first two are very easy to use, the length of the measurement is more difficult to use some. The Distance ruler uses the distance ruler to m

[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

say something in front.when one of our view interface is drawn on the Android screen, we actually have to go through these steps measure, layout, draw, we can see these functions in the view class, then there are several functions are onmeasure, OnLayout and OnDraw are some of the functions we need to be aware of when we rewrite our controls, so let's talk about the functions and roles of these functions. onmeasurejust as the name of this function is the mea
