The Crystallization Behavior of TiO2-CaO-SiO2-Al2O3-MgO Pentabasic Slag with a Basicity of 1.1–1.4

open access: yesCrystals, 2021
The utilization of titanium-containing blast furnace slag has been an unsolved problem for a long time. Failure to make effective use of the slag, which is caused by a high TiO2 content within it, not only results in a waste of resources, especially ...

Influences of High-Speed Train Speed on Tunnel Aerodynamic Pressures

open access: yesApplied Sciences, 2021
To comprehensively investigate the characteristics of aerodynamic pressures on a tunnel caused by the whole tunnel passage of a high-speed train at different speeds, we conduct a series of three-dimensional numerical simulations.

Min-Max Approach for High-Speed Train Scheduling and Rescheduling Models

open access: yesIEEE Access, 2021
The definition of train scheduling is going to shift its current static approach, as generally resulting in a timetable, towards a dynamic approach where the timetable can be modified in order to enhance the satisfaction of passengers’ demand.

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

open access: yesApplied 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 ...

Wind Tunnel Testing on Crosswind Aerodynamic Forces Acting on Railway Vehicles

open access: yesJournal of Fluid Science and Technology, 2010
This study is devoted to measure the aerodynamic forces acting on two railway trains, one of which is a high-speed train at 300km/h maximum operation speed, and the other is a conventional train at the operating speed 100km/h. The three-dimensional train

Hydrolysis behavior and mechanism of AlON powders

open access: yesMaterials & Design
AlON-C (∼25 μm) powders were prepared using the carbothermal reduction and nitridation (CRN) method. The powders were subsequently processed through milling to obtain AlON-M (∼1.6 μm) and AlON-F (∼456 nm).

Exploring Preferences for a Digital Single‐Session Intervention for Adolescent Siblings of Youth With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.
