simple, but the main features of multi-resolution analysis are all possessed. By learning Haar wavelet, the intuitionistic concept of multi-resolution analysis can be established. The fifth chapter introduces the multi-resolution analysis. The properties of multi-resolution analysis are given. For the sixth chapter constructs the Daubechies wavelet to manufacture many handy tools. The sixth chapter constructs the Daubechies wavelet. The seventh chapter is The application of Daubechies wavelet.
and summarized, the new version of the syllabus of the content has focused on refinement and deepening. By reading this book, candidates can master the knowledge of exam syllabus, grasp the key points and difficulties of examination, and be familiar with the test method, the form of examination questions, the depth and breadth of the questions, the distribution of the content, the methods and skills of solving the problem.(2) The System Architect Exam Test Center breakthrough, Case analysis, te

Security of a website involves many aspects. Code security is an important factor. Code audit is used to improve code security. So let's talk about code audit, this time we use dvwa.DVWA (Damn Vulnerable Web Application) DVWAIt is a set of WEB vulnerability testing programs written in PHP + Mysql for teaching and detecting general WEB vulnerabilities. Includes SQL injection, XSS, blind injection, and other common security vulnerabilities.The following is a simple example of code
It seems that it was an accidental example of the ecshop payment vulnerability last year. Share Interesting code auditing examples
Looks like the ecshop payment vulnerability last year
The occasional example is nice. Share
The code is as follows:
