The modem multi-media technology features the integration of the audio and video technologies and the simultaneous use of eyes and hands, embodies the inherent inspiration for its simulation, feedback, games, etc., and emanates enormous appeal. Its dynamic integration with physical education brings about a brand-new education approach in the history of physical education reformation. It has been involving to be an important education approach for PE teachers. Nevertheless, there are still a lot of key and difficult points that are not easy for the students to grasp regarding the application of modem multi-media technology to the physical education; and the teachers are weak in this new education approach and their course preparations are of low quality. Therefore, more attention needs to be paid to the integration of the advantages of multi-media teaching and the peculiarities of physical education so that multi-media technology can be made the best use in physical education.展开更多

These models are used as classifiers of normality to detect an occupant’s abnormal behavior.In order to express context information needed by reasoning and detection,multi-media ontology （MMO） is designed to annotate and reason about the media information in the smart monitoring system.A pessimistic emotion model （PEM） is improved to analyze multi-interleaving events of multi-active devices in the home.Experiments demonstrate that the PEM can enhance the accuracy and reliability for detecting active devices when these devices are in blind regions or are occlusive. The above approach has good performance in detecting abnormalities involving occupants and devices in a real-time way.展开更多

Despite of the convenience in collecting information to provide the decision basis for the users, the vulnerability of embed- ded sensor nodes in multimedia devices makes the malware propagation a growing serious problem, which would harm the security of devices and their users financially and physi- cally in wireless multimedia system （WMS）. Therefore, many researches related to the mal- ware propagation and suppression have been proposed to protect the topology and system security of wireless multimedia network. In these studies, the epidemic model is of great significance to the analysis of malware prop- agation. Considering the cloud and state tran- sition of sensor nodes, a cloud-assisted model for malware detection and the dynamic differ- ential game against malware propagation are proposed in this paper. Firstly, a SVM based malware detection model is constructed with the data sharing at the security platform in the cloud. Then the number of malware-infected nodes with physical infectivity to susceptible nodes is calculated precisely based on the at- tributes of WMS transmission. Then the statetransition among WMS the modified epidemic devices is defined by model. Furthermore, a dynamic differential game and target cost function are successively derived for the Nash equilibrium between malware and WMS sys- tem. On this basis, a saddle-point malware de- tection and suppression algorithm is presented depending on the modified epidemic model and the computation of optimal strategies. Nu- merical results and comparisons show that the proposed algorithm can increase the utility of WMS efficiently and effectively.展开更多

It is currently in the stage of "erosion adjustment". Affected by factors such as reservoir heterogeneity and long development time of steam flooding, the high permeability layer in the block has a single-layer breakthrough in the longitudinal direction and a one-way breakthrough of steam in the transverse direction, resulting in uneven reservoir utilization. In order to further expand the swept volume of steam and improve the efficiency of steam flooding, the multi-medium profile control and oil displacement technology research has been carried out, the formulation of high-temperature profile control agent and foaming agent has been optimized, and a reasonable injection method has been designed. The field implementation of 8 well groups has achieved remarkable oil increase effect, and this technology has broad application prospects.展开更多
