This paper proposed a MIMO cross-layer precoding secure communications via pattern controlled by higher layer cryptography. By contrast to physical layer security system, the proposed scheme could enhance the security in adverse situations where the physical layer security hardly to be deal with. Two One typical situation is considered. One is that the attackers have the ideal CSI and another is eavesdropper's...
Collaborative filtering (CF) is an important and popular technology for recommender systems. However, current CF methods suffer from such problems as data sparsity, recommendation inaccuracy, and big-error in predictions. In this paper, we borrow ideas of object typicality from cognitive psychology and propose a novel typicality-based collaborative filtering recommendation method named TyCo. A distinct...
This paper presents the solution of the team "ISSSID" for the Consumer Products Contest #1(CPROD1) of ICDM 2012. The contest provides a dataset including hundreds of thousands of text items, a product catalog with over fifteen million products, and hundreds of manually annotated product mentions. The goal of the competition is to automatically recognize product mentions in the textual content...
This paper presents a design procedure of static H∞ loop-shaping control for linear time-invariant system. The H∞ loop-shaping weights are selected by maximizing the robust stability margin of closed-loop system while ensuring that the resulting loop-shape lives in a pre-defined region. Existence conditions for a static output loop-shaping controller are given in terms of two linear matrix inequalities...
Threaded prefetching based on Chip Multiprocessor (CMP) issues memory requests for data needed later by the main computation, and therefore may lead to increased stress on limited shared cache space and bus bandwidth. In our earlier work, we had proposed an effective threaded prefetching technique that selects proper prefetch distance for specific application to improve the timeliness of prefetching...
Because of High-Pressure Swing Spraying Grouting Engineering Test needs more parameters to define, and the tests of construction unit are simple and bold, the engineering cost is very high. Through analyzing the internal relations between different parameters and comparing their importance by the introduction of the hydraulic formulas based on the South-to-North Water Transfer Project, this paper...
