A novel academic recommendation algorithm, MTAR (multi-type academic recommendation), which integrates resource content and user behaviors, is proposed to process five types of academic resources at the same time, which can quickly and precisely recommend academic resources of interest to users. The MTAR algorithm profiles five kinds of academic resources from four features including resource type,...
This paper investigate the performance of a proposed optical orthogonal frequency-division multiplexing (OFDM) in a short-range intensity-modulated, direct-detected (IM/DD) optical channel. Because of the high peak-to-average power ratio (PAPR) problem of the OFDM modulation scheme, the beneficial clipping method has been proposed to improve the performance of communication system. In the optical...
This paper proposes a smart grid policy simulation platform, which takes all information affecting the interests of the stakeholders into consideration, to set policy and conduct empirical analysis. The platform can help policy making departments to understand the policy implementation effect (e.g., environmental benefits) more intuitively by using visual analysis and reporting tools, so as to find...
During the expressed of the virtual battlefield situation, a lot of irregular objects have to be simulated. Particle system is an effect way for the modeling of fuzzy object, which need dynamic modeling. We expatiate on the application of the particle system from the aspect of tactics situation express and from two aspects: combat entity simulation and environment entity simulation, and analyzing...
