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 ...

Internet of things for high-speed railways

Intelligent and Converged Networks, 2021
As a new generation of application infrastructure and strategic emerging technologies, the internet of things (IoT) is an inevitable trend to be integrated into the rapid development of high-speed railways (HSR). This article first introduces the concept

High-speed trains: in microchannels? [PDF]

Journal of Fluid Mechanics, 2016
Kahkeshani et al. (J. Fluid Mech., vol. 786, 2016, R3) have studied particle ordering in suspension flow in a rectangular microchannel. Experiments and numerical simulations reveal that inertial focusing and hydrodynamic interactions result in long-lived ‘trains’ of regularly spaced particles.

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.

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

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).

AGAINTS AND FOR THE HIGH SPEED TRAINS’ MULTIMPLICATION [PDF]

Annals of the University of Oradea: Economic Science, 2008
In this exposure we intend to make visible the situation in which global warming is given by road and air transport, how could be revitalized railways, and how high speed trains could become a preferred mode of transport. But there is manifesting an opposition to railway development, nurtured by different interests, ranking from governments themselves,

Rational Use of Herbal Products in Pediatric Patients Treated With Anticancer Drugs in the European Union

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.

Tribo-Dynamic Behavior of Double-Row Cylindrical Roller Bearings Under Raceway Defects and Cage Fracture

Lubricants
High-quality data samples are essential for the early detection of bearing failures and the analysis of bearing behavior. The accurate simulation of bearing fault conditions can provide valuable insights into understanding failure mechanisms.
