Computer vision applications are frequently selected for short-term monitoring of bridges. The availability high resolution and frame rate consumer-grade cameras such as action makes the computer vision-based an attractive affordable option. This paper presents findings from deformations a steel girder footbridge subjected to cyclist loads captured with camera. A modified GoPro camera zoom lens...

This paper describes a system developed in LabVIEW environment to monitor the long term dynamic behavior of bridges. This system comprises three main parts: an automated signal processing toolkit, including automated vibration level detection and system identification; a database to organize the results, in text and graph format, generated from the signal processing toolkit; and a user-friendly...

With regenerative braking technology reaching maturity manufacturers are studying other forms of energy regeneration, amongst these, regenerative suspension. Although there have been several regenerative shock absorber developments over the past decade, including linear-tubular electric motors and hydraulic actuator based systems, cost and complexity have delayed large scale deployment in serie...

In the civil engineering field, fluid viscous dampers, used extensively in military applications, have found commercial applications on buildings and bridges subjected to seismic and/or wind storm inputs. Because fluid damping technology was proven thoroughly reliable and robust, implementation on footbridges to suppress undesirable pedestrian-induced vibrations is taking place. . This presenta...

Is it acceptable and moral to sacrifice a few people's lives to save many others? Research on moral dilemmas in psychology, experimental philosophy, and neuropsychology has shown that respondents judge utilitarian personal moral actions (footbridge dilemma) as less appropriate than equivalent utilitarian impersonal moral actions (trolley dilemma). Accordingly, theorists (e.g., Greene et al., 20...
