Stability evaluation of a railway timetable at station level

This research deals with a real-world planning problem in railway infrastructure operations. It is part of the RECIFE project, which seeks to develop a decision support software to help evaluate the capacity of a rail junction or station. To this end, the project is working on a timetable optimization model, as well as timetable evaluation modules. This paper presents a module for evaluating ti...

Railway station route searching based on ACA

In the railway station signal system, the route searching algorithm is an important software module to realize the function safety of this system. In the paper, the ant colony algorithm is applied to the railway station route searching. Take the specific station route-the Wangzhai Station route for example to search the shortest route. The ideas of the Wangzhai Station route searching are put f...

Has acromegaly been diagnosed earlier?

PURPOSE We investigated whether acromegaly has been diagnosed earlier at the Niigata Medical and Dental University Hospital. METHODS Patients with acromegaly (n = 81) who underwent their first transsphenoidal surgery from 2006 to 2015 were reviewed. Two groups were compared: those who underwent surgery between 2006 and 2010 (n = 35) and those who underwent surgery between 2011 and 2015 (n = 4...
