China's governance of its aging society has been accompanied by rapid economic and social transformation, urbanization, population migration, and globalization. Although the results have been remarkable, there remain several major challenges faced by its aging society and faced by the country in building a holistic response system for aging issues. This article uses governance theories to analyze...
Improving the intelligent ability of a robotic excavator is useful in practice, and this is a challengeable work due to the complex working environment of robotic excavation. In order to increase the performance of automatic control, operator model of robotic excavation derive from excavator driver is established to overcome the complex nonlinearities of the control system. The model is accordant...
Temperature and humidity monitoring system is an important part of laboratories, such as scientific experiment laboratory and quality testing laboratory. In order to supervise and record the temperature and humidity of geographical distributed constant temperature and humidity testing Laboratories, a web-based monitoring system is developed. The system is consisted of local data acquisition hardware...
In order to overcome the widespread issues on high rate of false alarm, low rate of detection and less suitability in system of detection intrusion, based on the variable fuzzy set, a dynamic model with self-adaptive ability and efficient detection on intrusion is proposed in the paper. In the pretreatment layer, the feature with light-computation and the efficient integrated mechanism are employed...
Coalmine gas concentration is a very complicated nonlinear dynamical system, which has obvious characteristics of chaos. Accurate prediction of coalmine gas concentration is very important to direct security production. However, data, got from in-wells, usually include noises, because of complex environment and multiple noises in-wells. Because of the capability of dividing frequency and diminishing...
Timely and scientific inspections and assessments of safety states are the key link to ensure the security of coalmine productions. The assessment methods directly affect the veracity and objectivity of results, and affect the overall safety management ability too. Combining the variable fuzzy set theory and the method of natural weight, a novel safety assessment model is proposed to evaluate intricate...
We propose an energy balanced clustering algorithm, which considers several important clustering parameters integrally, including node's relative velocity, distance, remaining energy and identification. The algorithm uses a filter mechanism to elect the most appropriate nodes to be the cluster heads, which breaks through the limitation of setting the weight parameters manually according to the network...
The time management (TM) is concerned with ensuring that the execution of the parallel discrete event simulation is properly synchronized. This is particularly important for simulations, not only to ensure that events are processed in a correct order, but also to ensure that repeated executions of a simulation with the same inputs produce exactly the same results. The goal of the synchronization mechanism...
In this paper, epoxidation of ethylene propylene diene rubber by in situ generated performic acid is discussed. The samples have been characterized by infra-red and 1 H-nuclear magnetic resonance analyses. Quantitative analysis of the reaction products is made possible by using the methyl deformation band at 1377 cm -1 as internal standard. The conversion of double bonds increases...
