According to the error rate calculation conclusion, there is another question here, which is how many hash functions should be selected. Too many hash functions can easily lead to lower computing efficiency and affect performance, and too few hash functions will increase the misjudgment rate. Happil...
lems are solved and the time complexity analysis. The recurrence, base cases and final answer calculation must each be accompanied with (often brief) worded reasoning to justify the correctness of the algorithm. Partial credit will be awarded for progress towards a solution. Question 1 You are pl...

Substation design adopts an object-oriented method, describes electrical components through graphical primitives and parameters, supports rotation, movement and other operations, and adds connection points to adapt to topology diagram drawing and transient calculation analysis. When drawing the connection ...
A forward calculation of the pre-mainshock stress state given by focal mechanism inversion of seismicity over the period before the 2019 Ridgecrest sequence (Hardebeck, 2020), shows it can explain a significant amount of the observed variability of the coseismic slip orientation along both the fore...

A time increment in the MPM typically has four calculation steps. Firstly, a shape function maps the information from the material points to the grid nodes. Then the momentum equations are solved to derive the unknown variables, and the nodal acceleration is obtained. Thirdly, the acceleration ...

The second method of performance optimization is IO read and write optimization. The common method is to use CPU pre-reading to improve Cache Miss. The above figure is to achieve the same calculation result through two methods of reading and writing. The method of reading and writing in rows...
