This paper proposes a novel tractable approach for accurately analyzing both the coverage probability and the achievable throughput of cellular networks. Specifically, we derive a new procedure referred to as the equivalent uniform-density plane-entity (EUDPE) method for evaluating the other-cell interference. Furthermore, we demonstrate that our EUDPE method provides a universal and effective means...
The electric vehicle is the main development direction for future new-energy vehicles. And the charging stations' planning and construction are the premise to promote the electric vehicle's use. In the light of the intensive traffic on the urban trunk road and its great charging demand of electric vehicles, this paper constructs a planning model of charging stations on the trunk road. The impact of...
Distribution grid will be impacted to some extent when large scale electric vehicles (EV) are discharging simultaneously. Firstly, the factors related to the discharging power of EVs are discussed. Secondly, the probability density statistic models of discharging time and discharging duration are built according to the traffic pattern of X city in China and the national household travel survey of...
This paper presents a novel method for electric vehicle charging station planning based on weighted Voronoi diagram. First, the traffic flow of each intersection node is used to represent the road network traffic. The number of charging stations is estimated in accordance with the capacity of conventional-standard charging station. The initial locations are determined by using coordinate method. Then,...
The paper proposed a method of locating and sizing of charging station for electric vehicle based on grid partition. This method is aimed at minimizing the users' loss on the way to the charging station, zoning the planning area with grid partition method, and choosing the best location of each partition in GA (Genetic Algorithm) on the consideration of traffic density and charging station's capacity...
A new method to design the wireless power transmission technology for medical endoscope is suggested. Discrete multiple coil structure with a driving system possessing the function of site-site wireless power transmission is adopted as the transmitting coils. Only the one that couples best with the receiving coil is selected to be driven to transmit power for medical endoscopes. It's theoretically...
A new 3D quadratic autonomous chaotic system is reported in this paper, which contains five system parameters and three quadratic cross-product terms, and the system can generate a pair of coexisting diagonal double-wing chaotic attractors with wide parameters ranges. Some basic dynamical behaviors of the new chaotic system are investigated. The Hopf bifurcation process is proved to arise at certain...
Based on relevant research on critical influential factors for pricing (CIFP) in urban transportation infrastructure projects (UTIP) product/servicepsilas under public-private partnership (PPP) scheme, a comprehensive theoretical model of UTIP product/service is proposed, which is tested for various types of such projects using structural equation model (SEM) with the data from questionnaire survey...
A new method of the model reference adaptive control for servo system what contains crawl phenomenon in a very low speed is presented based on hyperstability theory. In this paper, the mathematics model of the PMSM is studied, and basic hypothesizes is defined. The model reference adaptive controller is designed, and its stability is proved. Finally, the method is validated by simulating. Simulation...
