The RSA Cryptographic Protocol Is Not Secure  [PDF]
Cristian Dumitrescu
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.412222
Abstract:

In this article I describe a randomized algorithm based on random walks with two absorbing barriers that solves the satisfiability problem (known to be NP complete) with arbitrary high probability. As a consequence of this algorithm, I also prove that the RSA cryptographic protocol is not secure.

A Comparative Environmental Evaluation of the Coal and Natural Gas Life Cycle  [PDF]
Cristian Dinc?
Natural Resources (NR) , 2013, DOI: 10.4236/nr.2013.48060
Abstract:

Natural gas and coal are the main primary energy resources used in the Romanian energy sector, 73.7% in 2011, taking into account the fuel imports. The objective of the article consists in analyzing all the processes along the coal and the natural gas life cycle in order to assess their overall environmental impact. Two energy technologies were analyzed, for each resource: the pulverized coal combustion with supra-critical parameters and CO2 capture unit and the natural gas combined cycle. Considering the functional unit of electricity production for 1 year, it was found that the natural gas combined cycle remains the more interesting energy technology from an environmental point of view. However, the pulverized coal with supra-critical parameters equipped with a CO2 capture unit has the lowest environmental impact on the climate change. The weakest point of the coal technology is its low efficiency.

Specialization as a Personality Trait and Tendency: Introducing an Instrument of Measuring the Specialization Degree. Part 1  [PDF]
Cristian Vrachas, George Leontakianakos
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.615194
Abstract: Specialization constitutes a phenomenon which has been extensively researched in the framework both of the economic science—and its various structural cognitive fields—and also of the science of Biology. However, equivalent systematic attempt in evaluating the possible correlations and consequences of specialization in reference to multiple psycho-cognitive aspects of the individual’s personality is not observable from the point of view of psychological science. Objective of the current study is the introduction of a theoretical model of specialization as a dynamic variable, as a trend, and from that stand point to evaluate a person’s specialization degree in relation to other parameters of its psycho-cognitive being. In order to test the validity of the conception of specialization as a measurable factor, the Specialization Questionnaire (S.Q.) is created and introduced. More specifically, the S.Q. is aiming, on the one hand, at quantifying the degree of professional specialization and, on the other hand, at investigating the possible correlation between professional specialization and the tendency to seek for, respectively, specialized stimuli in other aspects of life, such as the personal-free time and the interpersonal relations.
