CARTESIAN AND SPHERICAL MULTIPOLE EXPANSIONS IN ANISOTROPIC MEDIA

Cartesian and spherical multipole expansions in anisotropic media

Abstract The multipole expansion can be formulated in spherical and Cartesian coordinates.By constructing an explicit map linking both formulations in isotropic media, we discover a lack of equivalence between them in anisotropic Sequin Shirt media.In isotropic media, the Cartesian multipole tensor can be reduced to a spherical tensor containing fe

Experiment and Simulation on the Anticollision Performance of a New Corrugated Steel Protection System for Bridge Piers

To ensure the safety of ships and bridges at the same time during collisions, a new type of bridge pier protection system is proposed, in which one is composed of corrugated steel plates, bolts, and corrugated steel pipes (CSP), and the other is composed of ordinary steel plates, bolts, and corrugated steel pipes (OSP).To study their anticollision

The nature and fate of natural resins in the geosphere XIII: a probable pinaceous resin from the early Cretaceous (Barremian), Isle of Wight

Abstract Terpenoid resin is produced by all families and most genera of the order Coniferales (the conifers), and the distribution of terpenes present in most conifer resins is characteristic of the originating family.Analyses of early Cretaceous (Barremian) amber (fossil resin) from the English Wealden, Isle of Wight, southern England, by pyrolysi
