BACKGROUND In the early stages of Pandemic (H1N1) 2009, border control measures were taken by quarantine stations to block the entry of infected individuals into Japan and community containment measures were implemented to prevent the spreading. The objectives of this study were to describe these measures and the characteristics of infected individuals, and to assess the measures' effectiveness...

Using modeling and simulation users can apply realistic interactions with their synthetic environments representing real world. In this study the synthetic environment is a hardware railroad model representing a miniature replica of a full-size railroad system under study. The hardware model is tested by means of real-time adaptive software simulator consisting of two subsystems: the virtual ra...

The participants in the grain logistics system need forecasts of railroad grain carloads. Although forecasting studies have been conducted for virtually every mode, no forecasting studies of quarterly railroad grain transportation have been published. The objectives of the paper are (1) specify a US quarterly railroad grain transportation forecasting model, and (2) empirically estimate the mode...

Attractive train schedules are quite important for the success of public rail transport. We consider schedules which are repeated after some xed time period. Periodicity is a well accepted, convenient attribute of all major railroad systems. Since trains share the public railroad network, we have to handle many connicting demands. Increasing competition from transportation alternatives as well ...

As a next generation of Global System for Mobile Communications – Railway (GSM-R), 3rd Generation Partnership Program (3GPP) Long Term Evolution (LTE)/ LTE-Advanced (LTE-A) is considered for railroad wireless communication, i.e., LTE-Railway (LTE-R). Railroad wireless communication has its own requirements and functions since railroad wireless communication is very closely related to safety. In...

In the 1930s, amidst concern about the ability of existing pension programs to provide former railroad workers with adequate assistance in old age, Congress established a national Railroad Retirement system. This system is primarily administered by the Railroad Retirement Board (RRB), which is an independent federal agency charged with providing benefits to eligible employees of the railroad in...

consider an individual’s Railroad Retirement benefit, other than the tier I benefit, in dividing property in a divorce case. This would treat Railroad Retirement benefits like other pension benefits. The only benefits paid to divorced spouses under the Railroad Retirement system are tier I benefits. Tier I benefits would continue to be immune from garnishment, attachment, assignment, levy, or o...

The railroad network carries 40 % of the freight in the US. Railroad bridges are the most critical part of the network and they need to be properly maintained for safety of operations. Railroad managers inspect the bridges to assess their structural condition. Railroad managers are interested in measuring displacements under train crossing events to prioritize their bridge management and safety...
