In order to determine influence of ventilation mode on dust distribution on fully mechanized heading face and explore dust reduction effect under different ventilation modes, the 209 fully mechanized heading face of Longde Coal Mine was taken as research object, and the software of FLUENT was used to simulate distribution of dust in the roadway and
Modeling in an emerging technology like RRAM devices is one of the pivotal concerns for its development.In the current bibliography, most of the models face difficulties 45 degree sharkbite in implementing or simulating unconventional scenarios, particularly when dealing with complex input signals.In addition, circuit simulators like Spice require
The transmission system is the key components of the helicopter,the study and analysis of the dynamics characteristic and virtual simulation have an important function for the whole life cycle dyna gel in every stage.The 3D model of the helicopter transmission system is established by CATIA software,the load under the typical working condition is c
Headwater streams contribute a significant proportion of the total flow to many river systems, especially during summer low-flow periods.However, despite their importance, the time taken for water to travel through headwater catchments and into the streams (the transit time) is poorly understood.Here, 3H activities of stream water are used to defin
Roller derby consists of two teams vying for points played on a flat oval track wearing quad skates.The specific research questions asked were: What are the characteristics of roller derby league members? What are the motivations of women who join roller derby leagues? What are reasons for continuing to participate? Do roller derby participants ide
