Circulation Problem

Train-set circulation problem is an important issue in operations of high-speed passenger trains in the world. On the basis of characteristics of the train-set circulation problem in China, an integer programming model is presented without considering distinct train-set types. With redefinitions of some basic mathematical objects and operations, an improved particle swarm optimization algorithm is proposed to solve the model. The algorithm is applied in a real-life case study based on the timetable of the Wuhan-Guangzhou High-speed Railway Line. The results show that the proposed algorithm is effective to find the optimized train-set circulation plan.

Circulation Problem

There are several goals I hope to reach in this talk. First, I would like to give this broad audience some idea of our present state of knowledge concerning global circulation of the sun—what the observations tell us (and don’t tell us!) as well as current theories. This will comprise a large part of my talk. In doing this, I hope I do not bore the specialists in this area. Second, I would like to put the problem of global circulation of the sun in the broader context of “solar variability”, a topic of rapidly growing interest in the solar community, that has implications for stars generally, and which may not have caught the attention of the stellar community. I would like also to put the solar circulation problem in the context of stellar rotation, by making a few admittedly speculative extrapolations to other stars. In addition, I will give a few of my own opinions about what we should be doing in the near future to make more progress in understanding the solar problem. And finally, I hope to provoke a wide ranging discussion of the whole area of circulation and variability in the sun and stars.

Purpose This paper aims to investigate the circulation of moist silica sand to provide appropriate feeding modes and references for designing the coating device when printing sand mold with line-forming. Design/methodology/approach First, this paper briefly introduces sand mold printing with line-forming and the circulation problem brought by moist silica sand. The outlet may be choked due to poor flowability and solidification characteristic, resulting in poor dimensional tolerance and even production failure. Then, based on circulation modeling, a series of feeding modes is proposed to guarantee adequate feeding, avoid solidification and ensure successful fabrication. Finally, the GUI of control software is developed, including slicing, path planning and the function of virtual printing. Findings Several feeding modes of moist silica sand are put forward to avoid the choke. Research limitations/implications The authors will further investigate the flowability of furan no-bake sand based on experiments. Originality/value This paper is going to provide references for the novel design of nozzle, prototype and sand mold printing, influencing significantly on mold manufacturing and the casting industry. This research applies equally to equipment having the circulation of high moist particles with solidification features.
