Role analysis helps us characterize users' interactions in a social network. However, previously proposed methods are mainly based on structural analysis of social networks rather than content-based behavior analysis. Therefore, we propose a method to use the content-based behavioral features extracted from user-generated content and behavior patterns to identify users' roles and to explore role change...
Information on Internet is so huge,and increases quickly. A huge information pool is coming up on the Internet. And much important information can be found on the Internet. Internet is really an important source of information. So extract the key words from the pages on Internet is so important. A page description model based on undirection graph is proposed and then a entity ranking algorithm named...
Let the observed sequence {yk} be generated by the multivariate ARMAX system A(z)yk = B(z)uk-1 + C(z)wk, where {wk} is the system noise with unknown covariance matrix Rw > 0, and {uk} is a sequence of mutually independent and identically distributed (iid) random vectors. Based on {yk} and {uk}, identification algorithms are proposed to simultaneously estimate the orders (p,q,r), the covariance...
The nonlinear problem of large deflection of a simply supported piezoelectric layered plate under initial tension is studied. The approach follows von Karman plate theory for large deflection for a symmetrically layered isotropic case including a piezoelectric layer. The thus derived nonlinear governing equations for the lateral slope and radial force resultant are solved using a numerical finite...
Consumer decision-making behaviors in the context of e-business attracted enormous researchers from different disciplines. Based on image theory and MMAU decision-making theory, we proposed a two- stage decision-making model of online consumer behavior. The model proposed that online decision-making process can be divided into two stages with the perspective of image theory. The model was tested by...
A unified recursive approach to i) identification for systems like ARMAX, nonlinear ARX, and others, and to ii) adaptive regulation of Hammerstein and Wiener systems is presented. By this method the problem under consideration is transformed to a root-seeking problem, to which the Robbins- Monro (RM) algorithm, the classical stochastic approximation (SA) algorithm, aiming at seeking for roots of an...
As the latest international video coding standard, H.264 is gaining importance not only on desktop computers but also on handheld devices. For handheld devices, power consumption of the system is of ultimate importance, which needs to be addressed at every layer of the system design. At the application layer, the code size affects the memory hierarchy behavior, which in turn affects the system power...
The problem of large deflection of a simply supported layered plate under initial tension is studied. The approach is based on von Karman plate theory for large deflection in deriving the nonlinear governing equations for the lateral slope and radial force resultant, followed by a non-dimensional scheme. To have a preliminary insight, however, only the linear problem is considered by neglecting the...
Conventional cache prefetching approaches can be either hardware-based, generally by using a one-block-lookahead technique, or compiler-directed, with insertions of non-blocking prefetch instructions. We introduce a new hardware scheme based on the prediction of the execution of the instruction stream and associated operand references. It consists of a reference prediction table and a look-ahead program...
