Art. XV.—Indo-Parthian Coins

Notes on the Chemical Composition of Parthian Coins with Special Reference to the Drachms of Orodes I

statistical study of the achaemenid, parthian and sassanid silver coins using elemental analysis by pixe technique

in this study, 27 achaemenid coins, 62 parthian coins, 66 sassanid coins, have been analyzed. the achaemenid coins as well as 20 parthian coins belong to the national museum of iran and the other 42 parthian coins are kept in tamashagah-e pool museum. sasanid coins belong to private collectors. using pixe analysis, the element concentrations of the coins were measured. by using statistical anal...

Moving coins

We consider combinatorial and computational issues that are related to the problem of moving coins from one configuration to another. Coins are defined as non-overlapping discs, and moves are defined as collision free translations, all in the Euclidean plane. We obtain combinatorial bounds on the number of moves that are necessary and/or sufficient to move coins from one configuration to anothe...

Detachable Electronic Coins

We propose a non-divisible electronic cash system that combines the restrictive blind signature technique and a batch signature scheme based upon the binary tree structure. Contemporary electronic cash solutions rely on the divisibility paradigm to achieve significant computational savings, and such techniques are considered to be the most efficient. We demonstrate an alternative approach that ...
