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...
Ion-exchange Polymer-Metal Composites known as a type of Electro-Active smart material has complex mechanism, and takes on nonlinear characteristic, which blocks its development and utilization. In this paper, a new model for electro-active smart actuator based on non-integer order models is proposed. An experimental setup has been realized to study the electro-active smart actuator non-integer behavior...
In academia, scientific research achievements would be inconceivable without academic collaboration and cooperation among researchers. Previous studies have discovered that productive scholars tend to be more collaborative. However, it is often difficult and time-consuming for researchers to find the most valuable collaborators (MVCs) from a large volume of big scholarly data. In this paper, we present...
Peripheral facial paralysis(PFP), a commonly seen disease in clinic, could occur at any age and has seriously threatened the health of human beings. Looking for a safer and more effective method to control the disease is one of the problems faced to modern medicine. By analyzing the advantages and the existing problems on acupuncture and moxibustion for the treatment of PFP, the relationship between...
This paper presents a novel platform as a workflow engine service which helps users to utilize cloud computing for addressing problems of large scale data processing without knowledge of underlying configuration details for computing applications. Our platform provides elastic resources for workflow applications to ensure that users leverage resources efficiently with the consideration of their budgets...
This paper presents a novel modulation and coding scheme (MCS) selection method to optimize the performance of Voice over Internet Protocol (VoIP) semi-persistent scheduling in Long Term Evolution (LTE) downlink. In VoIP traffic, the packet length little changes during a certain period and the cost of resource for the packet is related to this length. We exploit the characteristics and propose to...
Expressway is an important infrastructure which influences the development of national economic, while the management performance of expressway construction project is the key to succeed in expressway construction. This paper put forward an index system of influencing factors on the management performance of expressway construction project from the perspective of project management theory. To identify...
