(1/2, 1/2) REPRESENTATION SPACE — AN ab initio CONSTRUCT

12 pages (double space, 12 pt TNR)

Critical Infrastructure Protection requires the prioritization of critical assets and the evaluation of the criticality of infrastructures. However, criticality analysis is not yet standardized. In this paper we examine the relation between security risk and criticality. We analyze the similarities and differences in terms of scope, aims, impacts, threats and vulnerabilities and we suggest how ...

Structural and Electronic Properties of AuSin − (n = 4−12) Clusters: Photoelectron Spectroscopy and Ab Initio Calculations

AuSin − (n = 4−12) clusters were produced with a laser vaporization source and investigated by photoelectron spectroscopy. The swarm-intelligence-based CALYPSO structure search method and ab initio calculations were employed to determine their ground-state structures. The results revealed that the most stable isomers of AuSin − (n = 4−12) cluster anions are all exohedral structures, in which th...

An Ab initio Investigation of Pyrene Electronic Structure

Polycyclic aromatic hydrocarbons (PAHs) are a class of compounds consisting of more than twobenzene rings fused in a linear, angular, or clustered arrangement and do not contain hetero atomsor carry subsistent. PAHs originate from various sources. They are primarily formed byincomplete combustion of carbon-containing fuels such as wood, coal, diesel, fat, or tobacco. Thepresent study reports an...

An Ordinal Representation System for 12-Comprehension and Related Systems

The objective of this paper is to introduce an ordinal representation system which has been employed in the determination of the proof{theoretic strength of 1 2 comprehension and related systems.
