A pedestrian footbridge in Singapore was monitored for two weeks with a network of eight wireless accelerometer sensor nodes (Imote2). The nodes acquired 10 minutes of vibration data in the vertical direction every half an hour, processed the data using a novel embedded data processing algorithm and transmitted only the required results to the on-site base station. The base station then transfe...

This paper explores the effects of measurement uncertainty in structural health monitoring (SHM) applications. Uncertainty quantification is an essential part of effective design of next generation SHM systems for smart asset monitoring. Conventional measurement uncertainty analysis which is based on the GUM (Guide to the expression of uncertainty in measurement [1]) cannot straightforwardly be...

One of the objectives structural health monitoring (SHM) is to maximize information while keeping number sensors, and consequently cost sensor system, a minimum. Besides, configurations must be robust in sense that feasibility small errors inherent process not lead large variations final results. This paper presents novelties regarding robustness evaluation model measurement four most influenti...

Nominated for Eurosteel 2021 Best Paper Award Additive manufacturing (AM) is playing an increasing role in the production of complex steel structures. Robot- or machine-guided gas-shielded metal arc welding (GMAW), known as wire and additive (WAAM), suitable this purpose. A small footbridge was designed shell form at TU Darmstadt. It completely additively manufactured over a stream on site usin...

A substantial body of research supports a dual-process theory of moral judgment, according to which characteristically deontological judgments are driven by automatic emotional responses, while characteristically utilitarian judgments are driven by controlled cognitive processes. This theory was initially supported by neuroimaging and reaction time (RT) data. McGuire et al. have reanalyzed thes...
