An Improved Energy Management Strategy for Hybrid Energy Storage System in Light Rail Vehicles

Energies, 2018
A single-objective optimization energy management strategy (EMS) for an onboard hybrid energy storage system (HESS) for light rail (LR) vehicles is proposed. The HESS uses batteries and supercapacitors (SCs).

ANALYSIS OF DYNAMICS OF AMETRO VEHICLEMODEL WITH DIFFERENTIALWHEELSETS [PDF]

Transport Problems, 2017
The operating conditions of light rail vehicles (trams, metro vehicles) are predominantly different compared with those of passenger or freight trains. The increased number of low-radii curves has a negative effect on wheel–rail interaction.

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Track Geometry for Light Rail Systems

Transportation Research Record: Journal of the Transportation Research Board, 2010
Light rail systems are characterized by running over the streets, with semiexclusive (or reserved) right-of-way. This factor leads to the necessity of adapting the track geometry to that existing in the streets. This adaptation sometimes leads to great challenges: strong vertical grades, horizontal circular curves with small radius without ...
