Power models are crucial to assess the power consumption of base stations (BSs) without quantitive description. Currently available models seldom consider the dynamic factors such as indoor and outdoor temperature. As power model will affect the energy-saving gains of different green resolutions, in this paper we provide such power models for mobile communication BSs relying on practical data collected...
The rapid development of sports has attracted much attention in the digital network today. People's health awareness and world intense sports competition makes sports records get more and more attention. The rapid development of computer and network technology provide various fields with a lot of convenience. In order to make computer technology serve the College Sports education better, this paper...
This paper mainly introduces constructing Chinese new rural e-commerce platform based on logistics integration of Double E-markets and some key technologies. It has 4 sections: the first to briefly introduce current research status of rural E-commerce at home and abroad, and point out existing problems for developing e-commerce in Chinese rural areas; the second to originally propose a new rural double...
In order to provide the references for making and adjustment of plan, plan environmental impact assessment (PEIA) should adopt a holistic and systematic concept to study the movement laws of society-economy-environment composite system. With the catastrophe assessment model, the movement laws of society-economy-environment composite system in plan area are studied. The feasibility of the catastrophe...
Ecosystem health is the prerequisite for ecosystem service function. Assessment reflecting the trends of urban ecosystem health can improve 'information for decision making' on sustainability. Because urban areas are an advanced man-made complex ecosystem consisted of nature, society and economy, the key of urban ecosystem health assessment is to set suitable model for resolving the uncertainty of...
A new dynamic coupling device of hybrid electric vehicle (HEV) was put forward based on the traditional symmetric bevel gear differential. And the co-simulation platform was constructed based on AMESim and MATLAB by analysis of the transfer mechanism for the new dynamic coupling. The control strategy was developed using MATLAB, the dynamic model of HEV was built using AMESim, and the data exchange...
Based on the theory of system dynamics and the mechanism of supply chain system logistics funds supply and demand, we present the construction of the supply and demand balance system dynamics model and logic mathematical equations. When logistics system funds demand and supply is in pertubation, the logistics system self-organization can work to achieve the funds balance of supply and demand; when...
