NExT‐LF: A Novel Operational Modal Analysis Method via Tangential Interpolation

International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 401-414, September 2025.
ABSTRACT Operational modal analysis (OMA) is vital for identifying modal parameters under real‐world conditions, yet existing methods often face challenges with noise sensitivity and stability. This study introduces NExT‐LF, a novel method that combines the well‐known Natural Excitation Technique (NExT) with the Loewner Framework (LF). NExT enables the

Dynamic behavior of a cable-stayed footbridge depending on the calculation accuracy

Acta Polytechnica CTU Proceedings
Footbridges are analyzed in terms of dynamic response for pedestrian comfort. This problem is solved mainly on light and at the same time rigid constructions, which are easily oscillated by pedestrian load.

Computer vision wireless sensors for displacement influence line/surface measurement of footbridges using stationary pedestrian loading

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 23, Page 3688-3706, 19 September 2025.
Abstract Although using a heavy vehicle at a consistent speed is a common method to estimate displacement influence lines or displacement influence surfaces (DILs/DISs) of vehicular bridges, it requires algorithms to separate the dynamic and static components from measured displacements.

Pasarela para peatones y ciclistas

ARQ, 2002
Entendemos el trabajo del arquitecto como algo que opone cierta resistencia a la naturaleza: cubre del sol y la lluvia, divide del descampado, o salva un obstáculo.

Estimating preferences for different types of pedestrian crossing facilities [PDF]

, 2018
This paper reports the results of a study to understand the preferences of pedestrians towards using different types of road crossing facilities. A preliminary qualitative study found that people’s perceptions about crossing facilities are shaped by ...

Killing, letting die, and normative inertia

Philosophy and Phenomenological Research, Volume 111, Issue 2, Page 728-749, September 2025.
Abstract According to commonsense and deontological ethics, it is impermissible to kill a person in order to save the life of another person, all else being equal. But why? This article suggests a justification of this restriction. It appeals to the idea of normative inertia—very roughly, to the idea that in practical decisions, changing course is ...

Field Testing of a Smart Geomat Based on Fiber Optic Sensors and Sensor Fusion for Levee Monitoring

Journal of Flood Risk Management, Volume 18, Issue 2, June 2025.
ABSTRACT Real‐time monitoring of the functionality of river embankments, especially during flood events, is an increasingly important topic in the new scenario outlined by climate change. To address this issue, the concept of the “smart levee” has recently emerged, based on the fusion of information from different types of sensors to obtain, remotely ...

Impact of the Water Reservoir and River Engineering Structures on Longitudinal and Transverse (Dis)connectivity Associated With Sediment Transfer

Land Degradation &Development, Volume 36, Issue 8, Page 2609-2638, 15 May 2025.
ABSTRACT Human impact in the form of reservoir construction and river regulation downstream of reservoirs, is causing irreversible alterations to hillslope and river channel connectivity in river catchments. This disruption in the dynamic equilibrium of the river is attributed to sediment accumulation upstream of the reservoir's dam, limited sediment ...
