Experimental and theoretical investigation of railway wheel squeal [PDF]

, 2007
The tangential contact forces that arise at the interface between the wheel of a railway vehicle and the rail provide all the traction, braking, and guidance required by the vehicle.

Evaluating the Validity of Model Organisms: A Review and a New Framework for Biologists

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
This article provides an overview on model organisms and proposes a new framework for assessing the extent to which it is justified to generalize the results obtained from a given organism. It covers both studies of human diseases and those focused on general biological processes. The first part of the article is a review on model organisms.

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China

Energy Science &Engineering, Volume 14, Issue 9, Page 4095-4112, September 2026.
This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...

Vertical Vibration Reduction of Maglev Vehicles Using Nonlinear Model Predictive Control

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT This work presents a novel nonlinear model predictive control (NMPC) strategy for high‐speed Maglev vehicles that explicitly incorporates mechanical suspension dynamics into the control model. Unlike conventional approaches, which often neglect the interaction between levitation magnet and car body motion, the proposed method enables ...

Influence of Surface Processes on Intrarift Fault Displacement: 1.38 Million Years of Fault Slip Behavior in the Lake Malawi (Nyasa) Rift

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Surface processes, including hydroclimate variations, affect crustal deformation and fault behavior. These controls are especially important for intrarift faults in continental rift systems, which accommodate substantial strain while experiencing large hydrological load variations beneath rift lakes.

The development of rail-head acoustic roughness

, 2009
A model of the development of rail-head acoustic roughness on tangent track has been formulated. The model consists of a two-dimensional time domain wheel-rail interaction force calculation, with the normal force used as the input to a two-dimensional ...
