In this work, a multi-floor Poisson point process (MFPPP) model is proposed to analyze the performance of wireless networks inside a building, where the impact of penetration loss and floor height on the network performance is taken into consideration. According to the proposed MFPPP model, the coverage probability of the cross-floor max-signal-to-interference-plus-noise-ratio (SINR) association (CFMSA)...
In this paper, aim at mechanical hand brake circuit to establish the hydraulic model, utilize AMESim and MATLAB software to simulate the brake circuit, analysis circuit characteristic and the factors which impact brake circuit characteristic, find out the key factors that affect the braking circuit braking characteristics. And analysis simulation results, it show that the conclusion right and it is...
In order to accurately describe the reservoir physical property and its through-going characteristics, this paper establishes the sedimentary microfacies model and the microfacies controlled property model step by step using the facies-controlled modeling technology and on the basis of study results on geology, logging and development performance. The facies-controlled modeling reveals that the facies-controlled...
Three-dimensional geological modeling which is based on geologic and seismic results, displays three-dimensional visualization of the underground construction, reservoirs and sand body distribution, reveals the distribution of oil and gas and establishes geological model parameters to describe the distribution of oil and gas and characters of flow. It has deepened the understanding of the study blocks...
Although many methods for services composition can guarantee enforceability of services composition, they can not guarantee the rationality of services composition that can not determine whether an instance of services composition to achieve the desired target. Petri net-based model for grid services compositon is proposed for the grid application system in the paper. Then the reachability, boundedness,...
