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...
Information security evaluation has become an important part of information management. The methods of safety evaluation impact the veracity and objectivity of the results, and also impact the overall capacity of information management in enterprises. Based on the thought of variable fuzzy set, a novel risk evaluation model is proposed. This model can scientifically and reasonably determine the membership...
A novel alarming assessment model of coalmine gas is presented in this paper. Based on the information fusion technique of multi-sensor, we introduce the thought of variable fuzzy set to assess complicated and risk coalmine gas. Through information fusion we can get more effective and reliable data about coalmine gas. The method for variable fuzzy set theory can reasonable identify the relative membership...
The price of beef is determined by the carcass grade,and beef grade usually evaluated subjectively based on marbling level. It is a good method to determine marbling level with computer vision instead of person. The method assessing beef grade based on image processing was studied in this paper.The image of longissimus dorsi muscle was segmented using threshold, dilation and erosion, and the parameters...
UV-TiO2 photocatalysis have the characteristics of non-toxic and broad-spectrum sterilizing ability, its application in drinking water disinfection has taken much emphasis. This research was conducted in S waterworks which located in Nanjing and take Yangtze river as its source water. UV-TiO2 photocatalytic disinfection experiments were conducted in a self made photocatalysis reactor. Result showed...
A novel extension evaluation method of coal mines geological safety was proposed in this paper. Based on the extension theory, a matter-element model was established for qualitatively and quantitatively describing the safety evaluation problem of coal mines geological safety. The degree of relation based on the dependent function was employed to determine the nature and the level of the safety in...
