". The failure curve of electronic components varies with time. Through "Test re-screening" can only eliminate the early failure of the product, and can not reduce the failure rate during accidental failures. Therefore, screening can only improve the reliability of product use, and can not really improve the product's "intrinsic quality and reliability." Reliability is designed and manufactured. Component manufac

are very low.The database design problem, of course, is also very important, but for a few years of the system, tinkering is almost.For the coding problem, it is better to combine with the index, many times it is not an index problem, but your writing results in the optimizer does not use the index. In addition, if it is an index problem (no index, no index, no use, too many indexes, etc.), you can look at my other two index related articles:1. SQL Server Index Maintenance (1)--How to get Index

SPC is short for statistical process control. It is a process control tool based on mathematical statistics ". The basic element of SPC quality control is the control chart. A control c

to determine the authenticity of the error. LDRA Testbed 1) Definition: LDRA testbed provides powerful source code testing and analysis capabilities for application validation and validation, and is a unique quality control tool. It helps to improve the reliability, robustness and zero defect of computer software, and its use brings real savings in time, cost, and efficiency, which cann

stable change is not controllableThe basic stability change of ABR is controllable (real-time code rate change, but the average rate is approaching the target rate for a period)5. In the current X264 version (version 142), the ABR needs to be aware of two settings, 1.fps;2. Output frame pts calculation.1. FPs. The ABR estimates the average amount of data per frame based on the frame rate, bitrate/fps the average one frame of data.When the input video source is YUV data, it is necessary to expli

slightly more expensive. The quality assurance problem is the same. 17. Mitsubishi Black Rubber (2.5 yuan/Zhang) This is Mitsubishi's black rubber disk, the highest burning speed of 24X. The official said this is a music special disk, in fact, its record layer and deep blue is the same, may be better quality control. Its packaging is 25 pieces of a bucket, a tot

Introduction to HEVC code rate controlR-LAMDA model has been proposed to optimize for more than 2 years, from the article in recent years, broadly categorized as class: one is the rate of code rate control algorithm, one is the model parameter update, one is to consider the perceptionFirst Class:K0103The algorithm of bit rate control is mainlyp/bFrame on the prop

key point in cubic is that its window growth function depends only on the time interval value of the successive two congestion events, thus the window growth is completely independent of the network latency RTT, and the hstcp described earlier has a serious RTT inequity, The independent nature of the rtt of the cubic allows cubic to maintain a good RTT fairness between multiple TCP connections that share a bottleneck link.Stcp,scalable TCP.The STCP algorithm was proposed by Tom Kelly in 2003 to

Only Windows operating systems are supported.4.PVCS Merant Company's core products Pvcs,pvcs the latest version of PVCS8.0. In PVCS8.0, the functions supported by the process are integrated with PVCs. See the Internet on its introduction is not much, it is said to have been given to many large domestic

symmetrical. In the paving process, the spiral steering, speed can be adjusted to achieve no dead angle, no segregation cloth and two times stirring, to ensure the paving quality;(6) Easy to operate, simple: the entire work process can be done by the operator in a post-operation platform;(7) High reliability: With automatic and manual two sets of batching system, in addition to automatic batching, but also in the operating platform manually completed

Network traffic control is a very important part of LAN maintenance. It mainly involves the following methods: 1. Use a mask to divide the network segments into different network segments. This reduces the number of network broadcasts and enables fast communication between neighboring sites.　　 2. Create a VlanThe first advantage is that it can effectively curb the broadcasting and group broadcasting within the Organization and manage the bandwidth and
