Large anharmonic effects in the infrared spectra of the symmetrical CH<inf>3</inf>NO<inf>2</inf><sup>-</sup>·(H<inf>2</inf>O) and CH<inf>3</inf>CO<inf>2</inf><sup>-</sup>·(H<inf>2</inf>O) complexes
The MP2 method was used to optimize the geometries and to compute the quadratic and cubic force constants of CH3NO2-·(H2O) and CH3CO2-·(H2O). These were used to calculate the vibrational spectra and to identify the dominant couplings between fundamentals and various overtones and combination states. Near quantitative agreement was found between theory and experiment in both the CH and OH stretch regions of the spectra
Theoretical modeling of the OH stretch infrared spectrum of carboxylic acid dimers based on first-principles anharmonic couplings
A simple physical picture of the dominant cause for the unusual breadth and sub-structure of the O-H stretch infrared spectrum of carboxylic acid dimers was established. Cubic anharmonic constants were calculated for FAD and BAD using a set of five key internal coordinates
IOS Press How to fit cryptographic e-voting into smart cards
Abstract. The complexity of voting procedures make it challenging to design a secure electronic voting system. In many proposals, the security of the system relies mainly on a black box voting machine. Meanwhile, the most advanced proposals base their security arguments on (complicated) cryptographic protocols, e.g. blind signatures or homomorphic schemes. Canard and Traoré proposed cryptographic primitives dedicated to provide anonymous services using smart cards. Among these primitives, list signatures are specially suitable for e-voting, as they provide specific properties such as multiple vote detection. Moreover, unlike blind signatures, they do not involve a signing authority during the ballot creation process. The purpose of this paper is to present an e-voting system, whose security relies on a tamper-resistant smart card embedding several cryptographic primitives, including list signatures
