Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Access to Railway Stations in the Netherlands [PDF]
A rail journey is rarely an end in itself but almost always part of a journey ‘chain’ which include access to and egress from the railway station. The integration of the rail-journey components is essential to achieving a continuous travel, door-to-door,

Energy Science &Engineering, EarlyView.Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

THE HIGH-SPEED RAIL DEVELOPMENT IN THE NORTHEAST MEGAREGION OF THE UNITED STATES: A CONCEPTUAL ANALYSIS [PDF]
This paper examines the high-speed rail (HSR) development issues in the Northeast Megaregion of the United States (U.S.). Due to chronic underinvestment and a myriad of other factors, the only operational HSR in the U.S., i.e., Amtrak’s Acela Express, is

International Journal of Finance &Economics, EarlyView.ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade

Elevator dynamic monitoring and early warning system based on machine learning algorithm
IET Networks, EarlyView., 2022 In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.Abstract Objectives Our aim was to study the association between residential land cover and greenness during childhood and risk of developing celiac disease (CeD). Methods The Celiac Prediction in Skåne study prospectively followed 5969 human leukocyte antigen (HLA)‐genotyped children born 2001–2004 who were screened for CeD at ages 3, 9, and 15 years ...

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 ...
