Influential parameters in splash lubrication generated by a partially immersed rotating disc

Splash lubrication has been extensively investigated regarding churning losses. However, the highly chaotic nature of the projected flow still limits the ability to predict and to control lubricant distribution accurately, thereby restricting the optimisation of splash lubricatio...

Reflector‐Free, Highly Confined Love‐Like SAWs Enabled by a Phononic Metasurface for Real‐Time Monitoring of Cell Dynamics

ABSTRACT Surface acoustic wave (SAW) devices are widely used in sensing and biosensing but generally suffer from strong attenuation in liquid environments. Conventional approaches rely on reflectors to reduce these losses, yet these components remain difficult to optimize: limite...

From Versioned Cities to Versioned Documents: Extending CityRDF for Modelling Urban Documentation over Time

Cities are documented by large and heterogeneous multimedia corpora, including photographs, maps, plans, reports, videos, and web resources. While versioned urban models have been studied for representing the temporal evolution of city objects, the documents describing these obje...

A structure-preserving method of fundamental solutions for the multi-phase Mullins–Sekerka flow

A charge simulation method, a variant of the method of fundamental solutions, is applied to approximate the multi-phase Mullins–Sekerka flow in R 2 and in a half-plane H bounded by a Neumann wall W . In the underlying mathematical model, interfaces driven by their curvature are c...

Apparent Intramyocellular Lipid Index Using Spiral Magnetic Resonance Spectroscopic Imaging at 3 T

Abstract Purpose: This work introduces a rapid, high-resolution method based on spiral Magnetic Resonance Spectroscopy Imaging (MRSI) to map the apparent content of intramyocellular (IMCL) and extramyocellular (EMCL) lipids in human skeletal muscle. Methods: Unsuppressed water sp...

Determining a graph from its reconfiguration graph

Given a graph G and a natural number k , the k -recolouring graph C k ( G ) is the graph whose vertices are the k -colourings of G and whose edges link pairs of colourings which differ at exactly one vertex of G . Recently, Hogan et al. proved that G can be determined from C k (...

Influence of airflow, material type, and dripline density on gas transfer and bubble pathways in a pilot-scale aerated vertical flow treatment wetlands

ABSTRACT Oxygen transfer is a crucial element in the design of aerated wetlands. The presence or absence of dissolved oxygen has a significant impact on biological processes, and consequently, the efficiency of the degradation process. Typically, the air distribution system is si...

Hardware power consumption model for millimeter-wave massive MIMO antenna systems based on extensive circuit surveys

Abstract As millimeter-wave systems are deployed in 5G cellular networks and expected to expand to new frequency ranges in 6G, massive MIMO is a key technology to overcome the challenges of millimeter waves. The use of complex radio front-ends increases power consumption, and rel...

Active learning strategies for the estimation of a feasible set defined from a vector output black-box simulator

Many industrial problems require the use of black-box numerical simulators, for which it is essential to determine the set of so-called feasible input parameters. A set of parameters is feasible if the output of the code on these parameters satisfies given constraints, for exampl...
