A specialized topic cannot use a domain element in a content model 专门化主题不能使用内容模型中的域元素。
For a domain element , the value of the attribute must start with a plus sign 对于域元素,该属性的值必须以加号开始。
Similarly , a domain element can specialize only from an element in the base topic or in another domain 类似地,域元素只可从基本主题或另外一个域中的元素进行专门化。
( 3 ) for the first hierarchy mentioned above , the multiplication and inversion in gf ( pm ) are two key operations ( 3 )对于第一层次的运算,关键是域元素的乘法和乘逆运算。
When you define new types of topics or domain elements , remember that the hierarchies for topic specialization and domain specialization must be distinct 当定义主题的新类型或域元素时,请记住主题专门化和域专门化的层次结构必须有所区别。
First , it presents the basic concept and theory of the elliptic curve , discussing the choice of the coordinate system and fast realization of several point multiplication algorithm , studying all kinds of operation of the field element 首先介绍了椭圆曲线的基本概念和理论,讨论了坐标系的选择和几种标量乘算法的快速实现,研究了域元素的各种运算。
4 . based on the partition of equivalence classes , the resolving of linear equations and the calculation of the dual basis , three methodologies are proposed to determine the algebraic representations of coordinates of finite field elements with the elements themselves as the variable 4 、基于等价类的划分、线性方程组的求解和标准基之对偶基的计算,提出了域元素分量代数表达式的三种求法。
So , we put forward an optimized exponential algorithm in which the multiplication with itself was substituted mostly by square . through expanding of composition fields , the time consuming of optimal algorithm is , where n is the number of bits of exponential 通过对算法的分析我们可以得出结论,随着复合域的不断增大,域上指数运算所需的时间可近似表示为,式中n为指数以二进制表示时的比特串长度,为域元素进行多项式相乘所需的时间。
Ecc is considered to be an alternative to rsa . this article provides a brief description of rsa public key cryptography and the associated knowledge , in particular introduces non - supersingular elliptic curves e which is established on the finite field fp with p > 3 , in - depth studies present existed scalar multiplication , further proposes an improved signed sliding window algorithm on ecc under the mixed coordinates , the improved algorithm compatible the advantage of the naf , has the least number of zero window and avoid a large number of inverse operation , successfully reduce scalar multiplication calculation 本文阐述了椭圆曲线及其相关知识,特别说明了建立在有限域fp (其中p是大于3的素数)上的非奇异椭圆曲线e ,深入研究目前已有的各种标量乘法,由此提出了椭圆曲线密码算法在混合坐标下改进的带符号滑动窗口算法,该算法兼容了naf方法的优点,拥有最少数目的非零窗口数,又避免了域元素上的大量求逆运算,较成功地减少了标量乘法计算量。
Compared to the degree of approaching method , the fuzzy semantic relationship between fuzzy sets depends on not only the two fuzzy sets elements " subordinative degree , but also the elements " semantic relationship , while the degree of approaching only depends on the subordinative degree of the same element in different fuzzy sets , so the fuzzy semantic relationship method gets better results , and settle the problem of one text belonging to more than one class well . 3 两个模糊集间的语义关联度,不但依赖于两个模糊集论域的元素间的隶属度,而且与相应论域元素间的语义近似程度有关,而贴近度的方法只考虑了相同元素在不同模糊集中隶属度值的关系,因此模糊语义关联度的方法获得了更好的分类效果,并且更好地解决了文本兼类的问题。
