With the change to Web 2.0 Internet environment and the popularization of blogs, people write various writings freely on the Internet such as daily events, movie reviews, news, etc. Here, we can find writings on personal experiences from the past or on past popular culture. This paper analyzed collective memory through the blogosphere. We define blog posts that qualify as containing collective memory,...
In this paper, for an odd prime p, new quaternary sequences of even period 2p with ideal autocorrelation property are constructed using the Legendre sequences of period p. The distribution of autocorrelation function of the proposed quaternary sequences is also derived.
In this paper, a new generation method of quaternary sequences of period 2(2n-1) with ideal autocorrelation and balance property is proposed using the binary sequences of period 2n - 1 with ideal autocorrelation and reverse Gray mapping. The autocorrelation distribution of the proposed quaternary sequences is also derived.
We propose a new construction of quaternary sequences using the reverse Gray mapping of a pair of binary Sidel'nikov sequences. The proposed construction provides sequences of even period N with the maximum nontrivial auto-correlation magnitude, Rmax = 2. For N ?? 0 mod 4, the new quaternary sequences have the optimal Rmax = 2 and are almost-balanced in contrast to the only earlier optimal construction...
A metamaterial-based microstrip patch antenna with a symmetrical periodic structure is proposed in this paper. Additionally, the efficiency enhancement method of the proposed symmetrical periodic antenna (SPA) is also presented using triangular slots embedded on the ground plane. The proposed antenna has a monopole-like omni-directional radiation occurred by the characteristic of composite right/left...
All words are used in books, in which each are organized into a category through a library classification system. Therefore, words used by bloggers are also written in books, which in turn are categorized into specific categories. If a blogger uses a particular word often, we can anticipate that the blogger will have interest areas coinciding with the related book categories. This paper suggests that...
