The effect of hardware-computed travel-time on localization accuracy in the inversion of experimental (acoustic) waveform data

, 2017
This study aims to advance hardware-level computations for travel-time tomography applications in which the wavelength is close to the diameter of the information that has to be recovered. Such can be the case, for example, in the imaging applications of

Spacetime as a Feynman diagram: the connection formulation [PDF]

, 2000
Spin foam models are the path integral counterparts to loop quantized canonical theories. In the last few years several spin foam models of gravity have been proposed, most of which live on finite simplicial lattice spacetime.

Fabrication of foam concrete by use of novel foam generator — vortex jet apparatus: study of foam concrete properties

Industrial processes and technologies, 2023
A new method of foam concrete production by use of vortex jet apparatus (VJA) is studied. The foam produced by VJA exhibits high stability and narrow size distribution of the bubbles’ diameter and the latter correlates well with diameters of foam concrete pores.

Aftasten/Tantear: A sensorial, coalitional wayfinding among Muslim runners

Feminist Anthropology, EarlyView.
Abstract Muslim recreational runners in Muslim‐minority settings that take up running as their preferred form of leisure indicate that they feel they have to navigate a sense of exclusion when running outdoors. This article explores the process of exploration and sensing in public, represented by the Dutch verb aftasten, to investigate the way Muslim ...
