    • PURPOSE: A method for generating a polygonal pyramid element is provided to define an element in a master domain by using a mapping method and display an actual space element through the mapping method. CONSTITUTION: The coordinate of the one node of an atypical shaped polygonal pyramid is set up(S10). The weight function of a mathematical formula related to the one node of the polygonal pyramid is defined(S20). A shape function is acquired(S30), and the polygonal pyramid of the atypical shape includes a square pyramid, pentagonal pyramid and hexagonal pyramid and so on except a tetrahedron existing in a finite element method. The shape function of the polygonal pyramid is defined through the use of the MLS method.

    • An advertisement/keyword correlation weight decision system and a method thereof are presented to determine correlation weight and/or sequence of advertisements more objectively, by calculating correlation weight among advertisements on the basis of access information. According to an advertisement correlation weight decision system, an access information recording part(110) records access information for each advertisement according to the access to the advertisements from users. A correlation coefficient generation part(120) generates a correlation coefficient among the advertisements. A correlation weight calculation part(122) calculates correlation weight for the other advertisements from at least one advertisement. A rank decision part(130) determines rank of the advertisements using the correlation weight.

    • In order to attain an optimally compressed, narrow pulse peak at the filter output of a correlation filter for the purpose of reception, the interfering secondary maxima of the autocorrelation function of binary codes must be as small as possible. The invention uses specially designed signal codes which are used to generate the associated complementary signal code from the received sequence by means of evaluation in the reception filter. The subsequent parallel formation of the autocorrelation functions of the received signal code and the complementary signal code exhibits secondary maxima having an opposite mathematical sign, thus resulting in the desired perfect pulse peak having secondary maxima which are equal to zero during summation at the filter output.
    • 为了在接收目的的相关滤波器的滤波器输出端获得最佳压缩的窄脉冲峰值,二进制码的自相关函数的干扰次级最大值必须尽可能小。 本发明使用专门设计的信号码,用于通过接收滤波器中的评估从接收到的序列生成相关联的互补信号码。 随后并行形成接收信号码和互补信号码的自相关函数表现出具有相反数学符号的二次最大值,从而导致所期望的完美脉冲峰值具有在滤波器输出的求和期间等于零的次最大值。
