Encoding quantum-chemical knowledge into machine-learning models of complex molecular properties

Statistical (machine-learning, ML) models are more and more often used in computational chemistry as a substitute to more expensive ab initio and parametrizable methods. While the ML algorithms are capable of learning physical laws implicitly from data, ad ...

Dielectric Elastomer Actuator-Based Valveless Impedance-Driven Pumping for Meso- and Macroscale Applications

Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Francesco Clavica, Armando Matthieu Walter, Amine Benouhiba, Silje Ekroll Jahren

Impedance pumps are simple designs that allow the generation or amplification of flow. They are fluid-filled systems based on flexible tubing connected to tubing with different impedances. A periodic off-center compression of the flexible tubing causes the ...

Street grids for efficient district cooling systems in high-density cities

Shanshan Hsieh, Arno Schlueter

The feasibility of district cooling systems is linked to their efficiency, which is associated with their capital and operational costs. For reasons of ownership and maintenance, the piping network commonly follows the city's street layout. This paper exam ...

Folded-Tube Soft Pneumatic Actuators for Bending

Wyatt Marshall Felt

This article presents a model and experimental results for a new class of bending soft pneumatic actuators (SPAs) made from a single section of thin-walled flexible tubing. The actuator is formed by creasing the tubing into fin-like rectangular folds and i ...

Systematic Integration of Energy-Optimal Buildings With District Networks

François Maréchal, Luc Girardin, Ivan Daniel Kantor, Paul Michael Stadler, Raluca-Ancuta Suciu

The residential sector accounts for a large share of worldwide energy consumption, yet is difficult to characterise, since consumption profiles depend on several factors from geographical location to individual building occupant behaviour. Given this diffi ...

Fluid–structure interaction in pipe coils during hydraulic transients

Anton Schleiss, Pedro Filipe De Almeida Manso, David Ferràs Segura

The paper presents the analysis of fluid–structure interaction occurring during hydraulic transients in pipe coils by means of a four-equation model. The purpose is to understand and describe the effect of the coil movement on the transient wave. The four- ...

Stability Requirements of Deep Steel Wide-Flange Columns under Cyclic Loading

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

Just recently, valuable experimental data that characterized the hysteretic behavior of deep wide-flange steel columns (i.e., column depth, d >16 inches) at full-scale became available. Such members are typically used in steel moment-resisting frames (MRFs ...

Fluid-structure interaction during hydraulic transients in pressurized pipes

David Ferràs Segura

The aim of the present research is to identify, describe and quantify the principal mechanic-hydraulic relationships during hydraulic transients in pressurized pipe flows in view of improving pipe design and reduce pipe and system failure. Phenomena affect ...

Fluid-structure interaction during hydraulic transients in pressurized pipes: experimental and numerical analyses

David Ferràs Segura

Pressurized pipes may be endangered by failure due to excessive hydraulic transients, the so-called waterhammer. These pressure waves are strongly affected by fluid-structure interaction (FSI), unsteady skin friction, dry friction or pipe-wall viscoelastic ...
