Malus sieversii (Ledeb.) Roem. is a wild apple species which is distributed in the western mountains in Xinjiang, P.R. China, as well as in Central Asia, including Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and Turkmenistan. M. sieversii germplasm is valuable for plant breeders for drought, cold and disease resistance. Genetic polymorphisms of 20(More)
Combining with ventilation requirements and safety regulation in coalmine, control strategy which aims at both safety and energy saving is established at length. Moreover, conventional double fuzzy control model is found to carry out two work mode, normal ventilation and gas discharging. Since four input signals affect output in different degree, three(More)
Researching on gas discharging system on heading laneway in coal mine is extremely urgent since gas exploring accident takes loss immeasurable. In order to satisfy normal ventilation function and exceeding limited gas discharging function, a double model fuzzy control model using MATLAB language in the Simulink dynamic simulation tools is established.
