Train Scheduling Problem - Phase I: A General Simulation Modeling Framework
One of the important problems in management of railway systems is train scheduling problem. This is the problem of determining a timetable for a set of trains that do not violate infrastructure capacities and satisfies some operational constraints. In this study, a feasible timetable generator framework for stochastic simulation modeling is developed. The objective is to obtain a feasible tr...
متن کاملRunaway collisions in young star clusters. I. Methods and tests
We present the methods and preparatory work for our study of the collisional runaway scenario to form a very massive star (VMS, M∗ > 400M⊙) at the centre of a young, compact stellar cluster. In the first phase of the process, a very dense central core of massive stars (M∗ ≃ 30− 120M⊙) forms through mass segregation and gravothermal collapse. This leads to a collisional stage, likely to result i...
متن کاملRunaway quarks.
When heavy nuclei collide, a quark-gluon plasma is formed. The plasma is subject to strong electric field due to the charge of the colliding nuclei. The electric field can influence the behavior of the quark-gluon plasma. In particular, we might observe an increased number of quarks moving in the direction of that field, as we do in the standard electron-ion plasma. In this paper we show that t...
متن کاملRunaway electrons and ITER
The potential for damage, the magnitude of the extrapolation, and the importance of the atypical—incidents that occur once in a thousand shots—make theory and simulation essential for ensuring that relativistic runaway electrons will not prevent ITER from achieving its mission. Most of the theoretical literature on electron runaway assumes magnetic surfaces exist. ITER planning for the avoidanc...
متن کاملRunaway cultural niche construction.
Cultural niche construction is a uniquely potent source of selection on human populations, and a major cause of recent human evolution. Previous theoretical analyses have not, however, explored the local effects of cultural niche construction. Here, we use spatially explicit coevolutionary models to investigate how cultural processes could drive selection on human genes by modifying local resou...
