A Review of Interferometric Synthetic Aperture RADAR (InSAR) Multi-Track Approaches for the Retrieval of Earth’s Surface Displacements

open access: yesApplied Sciences, 2017
Synthetic Aperture RADAR Interferometry (InSAR) provides a unique tool for the quantitative measurement of the Earth’s surface deformations induced by a variety of natural (such as volcanic eruptions, landslides and earthquakes) and anthropogenic (e.g ...

Slum‐Based CAV Networks: Networking in Unyielding Poverty Situations

open access: yesStrategic Change, EarlyView.
ABSTRACT Over a billion of the world's population reside in slums. However, the configurations of their social and structural ties in these environments remain unsubstantiated. Drawing on a psychosociological rational choice perspective, we introduce theoretical explanations distinguishing slum dwellers' behavior, actions, and attitudes in community ...

Vladimirov–Pearson operators on ζ$\zeta$‐regular ultrametric Cantor sets

open access: yesMathematische Nachrichten, EarlyView.
Abstract A new operator for certain types of ultrametric Cantor sets is constructed using the measure coming from the spectral triple associated with the Cantor set, as well as its zeta function. Under certain mild conditions on that measure, it is shown that it is an integral operator similar to the Vladimirov–Taibleson operator on the p$p$‐adic ...
