Influences of High-Speed Train Speed on Tunnel Aerodynamic Pressures

Applied 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

IEEE 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

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 ...

Wind Tunnel Testing on Crosswind Aerodynamic Forces Acting on Railway Vehicles

Journal 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

Multifunctional strut-plate composite lattice metamaterial for integrated acoustic, energy, and vibration management

Virtual and Physical Prototyping
In the pursuit of engineering solutions capable of managing persistent hazards such as noise, vibration, and structural impacts, materials that combine sound absorption, vibration damping, and deformation resistance are crucial.

Hydrolysis behavior and mechanism of AlON powders

Materials & 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).

Increased Risk of Sarcomas in Children With Congenital Anomalies: Findings From the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Registry Linkage Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.
