What is tracking error?

1. Tracking error refers to the difference or deviation between the actual tracking result and the expected tracking result in the target tracking or control system. This difference is caused by factors such as sensor noise, environmental interference or algorithmic limitations. The size and nature of the tracking error are very important for evaluating system performance, optimizing control algorithms or adjusting system parameters.

2. Tracking error is the yield standard deviation of the difference between the portfolio rate of return and the benchmark rate of return, which reflects the risk of fund management. It can measure the relative risk of the portfolio in achieving the real investment goal of investors, which is an effective risk measurement method.

3. Tracking error is the deviation of the portfolio relative to the benchmark index. If the tracking error is smaller, the closer the performance of the portfolio is to the benchmark index; on the contrary, if the greater the tracking error, the greater the difference between the performance of the portfolio and the benchmark index.

4. Tracking error refers to the deviation or error in the tracking system. This error usually comes from various sources such as technical equipment, human factors or environmental factors. Tracking errors may affect factors such as the delivery time, location and quantity of the item.Reasons There are usually the following reasons for tracking errors.

Detailed explanation of automatic tracking system

1. Detection device: It usually contains flame detectors, temperature detectors, etc., which are used for Perceive the existence of the fire source. These detectors are generally installed in areas where a fire may occur, and when a fire is detected, it will send a signal to the control device.Control device: This is the "brain" that automatically tracks the jet fire extinguishing system.

2. Need. After the oppo system tracking is turned on, the system will automatically locate your mobile phone. You can also click the location to locate, and you can find your mobile phone according to the map. Tracking focus is an autofocus mode that can predict the speed and direction of the dynamic subject and automatically adjust the focus tracking.

3. The automatic tracking system is a system that continuously tracks and measures the trajectory parameters of the moving target. The target of the automatic tracking system is vehicles, ships, aircraft, missiles and artificial satellites moving at a certain speed and acceleration.

4. Automatic tracking can provide spatial positioning, posture, structural behavior and performance of the movement target, which is a multi-functional and high-precision tracking of the movement target andMeasurement means, automatic tracking is composed of position sensor, signal processing system, servo system and tracking frame and other parts.

5. Automatic tracking technology is actually composed of a large number of sensors and control systems. At the first front of the car, there is a radar sensor to monitor the distance of the vehicle in front, a speedometer to measure the speed of the other party, and several radar sensors on the left and right sides to monitor whether there are oncoming cars on both sides of the car body.

6. To this end, countries around the world are vigorously developing intelligent transportation systems. Vehicle automatic tracking is an important part of advanced assisted driving in the intelligent transportation system ITS. It aims to ensure that in the traffic environment, the rear car can automatically follow the movement of the front car and maintain a reasonable safe distance from the front car, which not only ensures safety but also improves driving efficiency, but also reduces fuel waste.

The purpose of implementing defect tracking is

1. The purpose of software testing is to find out as many software defects as possible. ( Y) Beta test is a kind of acceptance test. ( Y) The acceptance test is carried out by the end user. ( N) Testers do not need to submit any workpieces before project establishment. ( Y) Unit tests can detect about 80% of software defects.

2. Software testing is to find defects earlier and faster. In other words, the discovery of defects can be regarded as one of the main results of the testing work. The Implementation Of Software Defect Management Has At Least The Following Three Basic Purposes: Software Defect, Often Called Bug.

3. Quality control is to passMonitor the quality formation process and eliminate the factors that cause unqualified or unsatisfactory effects at all stages of the quality ring. In order to meet quality requirements and obtain economic benefits, various quality operation techniques and activities are adopted.

4. It may be necessary to make a change request for these deliverables to carry out defect remedialy. (4) Project file update The project documents that can be updated in this process include: lesson register, demand documents, demand tracking matrix. The control scope is the process of supervising the scope status of projects and products, and managing the scope benchmark changes.

5. Engineering quality problems are caused by unqualified engineering quality or engineering quality defects. In the process of any engineering construction, due to various subjective and objective reasons, the occurrence of unqualified items or quality problems is often inevitable. For this reason, asSupervising engineers must master how to prevent and deal with unqualified items and various quality problems in construction.

How to turn on the shutdown event tracking function of the notebook win7 system to solve the abnormal shutdown problem

method Press "WIN+R" to open the "Run" window, enter Enter the "regedit" command to open the "registry editor". In the open "Registry Editor", locate the following registration items "HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows NTReliability".

Method group policy method Run gpedit.Msc; open Computer Configuration in turn; Administrative Templates; System; RHS; Display S Hutdown Event Tracker policy (display shutdown event tracking policy); double-click to open.

First, open the win7 system, select "Computer" on the desktop, select "Manage" in the right-click menu, and click Open. Then, in "Computer Management", select "Event Viewer" and click Open. Then, select "Windows Log" and click Open.

Of course, you alsoYou can not select it, that is, to view all events related to power operation, such as standby, hibernation, etc.; and then click the "OK" button.

But due to system jam or other reasons, forced shutdown is inevitable, so what should I do? Next, the editor will share with you how to repair the win7 system through the computer's built-in error check mechanism after the forced shutdown of the win7 system.
