The goal of the train timetable problem is to determine departure and arrival times to or from each station in order to prevent collisions between trains and effective utilization of resources. The two proposed methods are based on integration of a simulation and an optimization method to simulate train traffic flow and generate near optimal train timetable under realistic con- straints including stops for track maintenance and praying. The first proposed method integrates a cellular automata (CA) simulation model with genetic algorithm optimiza- tion method. In the second proposed approach, a CA simulation model combines with dynamically dimensioned search optimization method. The proposed models are applied to hypothetical case study to demonstrate the merit of them. The Islamic Republic of Iran Railways (IRIR) data and regulations have been used to optimize train timetable. The results show the first method is more effi- cient than the second method to obtain near optimal train timetabling.展开更多

That brings back my childhood memory of people in my native town—officials plus the local gentry and elderly—going to the Dragon King Temple to pray for rain. Before that, they would fast and perform ablution. Once in the temple, they would offer sacrifices to the "Dragon King," a fierce-looking clay or wooden sculpture, who is said to take charge of distributing rain. Amid smoke that kept rising展开更多

Use the theory of Feminism to analyze it. The results confirms to be walking a fine line between critical self- insight and obsessive self- importance and insists that a lot of Elizabeth's own experiences can make the readers especially women learn to be stronger and more independent. Besides that the novel Eat, Pray, Love can have a heavy touch on the readers. People becomes more materialistic and always pursuit the worldly happiness in modern time. Eat, Pray,Love is also can make readers learn to respect other cultures. While the strengths of this novel are the unique format, the simple language styles which can make the readers more acceptable, the flexible use of foreign languages, and the cultural diversity.This novel also has weaknesses such as the viewpoint in subjective way and the plot in complicated way.展开更多

A 3-year monitoring study using sex pheromone traps in semi-arid and arid olive groves was performed. In the semi-arid grove, flight pattern of the OM was the same as in other Mediterranean countries, but in dates concordating plant phenology. The moth completes three generations annually: the first flight is in March to April, the second is in May to June and the third occurs in August to October. In the arid olive grove, an interesting flight pattern was observed. First flight was always very close or overlapped with the second one with no male catches during August to October. However, eggs were present most of the season, indicating unusually high female presence and oviposition activity of the OM during the absence of males in the traps. Generally, moth densities were significantly lower in low fruiting years than in higher ones and were also lower in the arid olive grove than in the semi-arid one. In contrast, JM males were present all season, exhibiting six to seven and three to four overlapping flight peaks in arid and semi-arid olive groves, respectively. Moth densities were significantly higher in the arid olive grove than those in the semi-arid one. This study shows that trapping location and fruit beating year are characteristics that strongly affect the grove-specific information needed to estimate correctly adult emergence and thus the timing of control measures.展开更多
