表面张力N-S方程零等值面函数自由面流体的温度或组成的变化,都会引起表面张力的变化.因而在研究有关自由面的流体运动中,都要考虑自由面上的表面张力.本文利用当前流行的求解自由面的LevelSet方法给出含表面张力的N-S方程的推导.doi:10.3969/j.issn.1674-148X.2003.02.015高玉丽宁夏大学数学计算机学院CNKI青岛农业大学...
在这个示例中,我们创建了一个名为 my_index 的索引,并设置了 index.max_ngram_diff 为5。同时,我们还定义了一个自定义的 NGram 分词器 my_tokenizer,其中 min_gram 为3,max_gram 为8。由于 max_gram 和min_gram 之间的差值为 5(8 - 3 = 5),这符合我们设置的 index.max_ngram_diff 值。 4. 设...

In this paper, 2 efficient reverse converters are introduced for the four-moduli set {2n1, 2n–1, 2n1–1, 2n+1–1} which offers a high speed arithmetic unit due to its balanced modulus in the form of 2kand 2k–1. The proposed converters are designed in two-level architecture. ROM ...

Digital lockset for entry-level applications.(New Products)
aThe trigger level can be used to set the starting point of the wave. For the sine wave, the starting phase can be changed. Please note that if the trigger level is adjusted to be over negative or positive, there would be no sweep signals since the trigger level is excess the amplitude...
aWhen the MPE threshold was set to 5%, the number (17) and the proportion (0.19) forecasts with MPE was out of interval h0.05, 0.05i. A confidence interval for this proportion h0.11; 0.27i has been designated at the significance level a = 0.05. That means worse MPE values than 5% ...

One of the most popular level set algorithms is the so-called fast marching method (FMM), which requires total O(N log2 N) operations, where N is the number of grid points. The article is concerned with the development of an O(N) level set algorithm called the group marching method (...
