The Rejection of Consequentializing [PDF]

, 2021
Consequentialists say we may always promote the good. Deontologists object: not if that means killing one to save five. “Consequentializers” reply: this act is wrong, but it is not for the best, since killing is worse than letting die.

On the use of a simple tuned mass damper model for reducing the excessive vibration of tsunami evacuation suspension footbridge

MATEC Web of Conferences, 2018
The suspension footbridges are commonly constructed in the rural area. The constructions method is relatively simple compared to other types of bridges, thus as consequence, the construction cost also becomes relatively cheaper.

Non-local first-order modelling of crowd dynamics: a multidimensional framework with applications [PDF]

, 2010
In this work a physical modelling framework is presented, describing the intelligent, non-local, and anisotropic behaviour of pedestrians. Its phenomenological basics and constitutive elements are detailed, and a qualitative analysis is provided.

Assessment of human-induced vibrations of a cable-stayed footbridge

MATEC Web of Conferences, 2018
The primary purpose of this research is the evaluation of human-induced vibrations of a cable-stayed footbridge. The cable-stayed pedestrian bridge with total length of the span equal to 46.90 m located in Czestochowa (Southern Poland) was chosen as a ...

Understanding pedestrian bridge usage considering perception and socio-demographic characteristics of the road users in Dhaka city

Transportation Research Interdisciplinary Perspectives
Walking often involves crossing a road, where the chance of vehicle–pedestrian conflict increases. Footbridges are one of the engineering instruments that offer safety for pedestrians during road crossing avoiding any physical conflicts with pedestrians.
