X-ray tomography (tomography)There are two different imaging methods in business: CT, MRI, and the two methods have some similarities in the method of realization, which is about Ct.A body profile is assumed to contain a variety of sticky substances, such as bones, muscles, blood vessels, and spinal cords, described by variable density function $\mu (x_1,x_2) $. If we know what $\mu$ is, it means that we can know the condition of the body profile.About $\mu$, in the notes Professor recommended u

B) Use serde (serialize/deserialize) to format data during data serialization and deserialization.
This method is a little more complex, and the data control capability is also weaker. It uses regular expressions to match and process data, and th

This article mainly uses Tomcat as the middleware and describes the specific signature steps. $ java_home is the JDK installation directory, and $ atat_home is the tomcat installation directory.
To sign an applet, follow these steps:
1. Set the environment vari
