Using High-speed Train Induced Signal to Estimate High-Speed Train Acceleration

Journal of Physics: Conference Series, 2023
Abstract A moving high-speed train (HST) stimulates various seismic waves near a high-speed railroad (HSR). Thus, the HST has been treated as a combined and moving seismic source. Moreover, the speed and acceleration of HST are typical moving parameters for this HST seismic source. Certain devices, such as GPS, Doppler radar, and cameras,

Seamless LTE connectivity in high‐speed trains [PDF]

Wireless Communications and Mobile Computing, 2015
AbstractHigh‐speed train (HST) is revitalizing the train as a preferred mid‐range transportation system. The provision of broadband Internet connectivity onboard trains is one of the key challenges in the competition among train operators. Unprecedented spectral efficiency and data rates (up to 100Mbps in high mobility) of the Universal Mobile ...

The Effect of High Load Training on Psychomotor Speed [PDF]

International Journal of Sports Medicine, 2007
The purpose of the present study was to investigate whether overreached athletes show psychomotor slowness after a period of high load training. Fourteen well-trained cyclists (10 male, 4 female, mean age 25.3 [SD = 4.1] years, mean maximal oxygen consumption 65.5 [SD = 8.1] ml/kg.min) performed a maximal graded exercise test on a cycle ergometer ...

The Future of High-Speed Train

IEICE Transactions on Information and Systems, 2005
High-speed intercity railways have grown into profitable business, achieving a renaissance in rail transport. High-speed railways need constant updating to new systems if they are to be winners in this age of competing transportation modes. In view of that situation, JR East started an R&D project to achieve even faster speed---more than 300 km/h.

Optimising low acoustic impedance back-fill material wave barrier dimensions to shield structures from ground borne high speed rail vibrations [PDF]

, 2013
Ground borne vibrations generated due to high speed train passage can cause undesirable effects on the nearby environment. One approach to mitigate vibration levels is to use "wave barriers", however their installation cost may be very high.

A Finite-Element Model of Seated Human Body Representing the Distribution of Static Pressures and Dynamic Forces over a Rigid Seat During Vertical Vibration for Sitting Postures with Various Thigh Contact

Applied Sciences
Overall sitting comfort is related to both static pressure distribution and dynamic human–seat interaction during vibration. This study proposes a simplified finite-element model of the seated human body that could potentially be used to assess overall ...
