Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this second part of our series of papers, we develop an abstract framework suitable for de Rham complexes that depend on a parameter belonging to an arbitrary Banach space. Our primary focus is on spectral perturbation problems and the differentiability of eigenvalues with respect to perturbations of the involved parameters. As a byproduct,

Log Jams at a Bridge with a Pier and a Bridge without Pier
Procedia Engineering, 2015 AbstractA flume experiment was carried out in a rectangular flume in order to investigate interaction between two different model bridges and logs from the viewpoint of flood disaster prevention. Logs is assumed representative of flowing wood during floods. The model bridge with a pier and model bridge without pier were used as an obstruction in rivers.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

Impacts of bridge-pier types on balancing ice jams: an experimental study
Shui kexue jinzhan, 2018 The presence of ice jam increases the possibility of upstream water level, which can easily trigger ice jam flooding. Bridge pier types can significantly influence backwater heights.

Journal of Field Robotics, EarlyView.ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

Sustainable Development, EarlyView.ABSTRACT Understanding the environmental impact of food production is critical to promoting sustainable consumption patterns. This study explores the gap between consumers' perceived water footprint (PWF) and the actual water footprint (AWF) of selected agri‐food products in Italy, including crop‐ and animal‐based products. A survey conducted through a
