I am going to add a performance monitoring report function to JDBMonitor. In "report condition", enter the start time, end time, and unit time for statistics, and click query. The program collects statistics from the table T_LOG_SQLLog recorded by DataBaseDBListener and displays the report. For example, you can enter "18:00:00" in the start time and "12:00:00" in the end time, select "5 minutes" in the time unit, and click "query ". The program filters out records with FbeginTime greater than or

(0) * L ^ (2n-1)Each coefficient is a convolution of A and B, but the calculation result may exceed the range [0, L). The final adjustment is required.Convolution can be calculated through discrete Fourier transformation. If two square numbers are calculated, the Fourier transformation can be less than once. The following is the code for calculating the number of self-defense, using the Fourier transform function in Intel MKL:# Include # Include # In

The following code originates from http://blog.csdn.net/nuaazdh/article/details/7059630 and is slightly modified with "g++-O Bank bank.c" compiled under CentOS. Every time the system randomly generates 1, the current customer customer's counter is serviced by 2. The current customer and next customer arrival time interval, remember that these 2 points understand the entire code, the book is not very clear. The waiting time for each customer in the bank depends on the departure time of the previo

Recently in the chapter on the graph theory of discrete mathematics, here is my classification and summary of some important concepts of the graph. Describe the concept of relationships Association--used to describe the relationship between a point and an edge, which simply means that the edge is made up of those points and is associated with those points. The correlation matrix is a matrix that records the number of points in the Edge Association.
