This paper summarizes the characteristics of the electricity load data collected every 15 minutes of power users. The single-day load data of single power user is taken as a 96-length vector, and the single-day data of n users is taken as a 96-column set. Single-user monthly data and annual data are described as a 30 (31) × 96 matrix and a 365 (366) × 96 matrix respectively. By comparing the wavelet...
Distributed Denial of Service (DDoS) attack presents the following characteristics, that the botnets become extra-large scale, the mode of attack presents a variety of characteristics and the application-level attacks become the main attack approach, which seriously impact on Internet Security. However, traditional software defense detection means have such problem, that the accurate rate is too low,...
The self-index is a kind of highly compressed, self-contained full-text index. It is designed for indexing plain texts in order to reduce its permanent storage, as well as to enhance searching performance. Apart from being a sequence of characters, usually the text has specific internal structure. The data record, as a basic model of structured data, is therefore employed to represent and organize...
Measurement of visual quality is crucial for various image and video processing applications. Traditional measurements convert the spatial data into some feature domain, such as the Fourier domain, and detect the similarity, such as mean square distance or Minkowsky distance, between the test data and the reference or perfect data. In this paper we approach image quality assessment by presenting a...
