The University of Informatic science is a university research center based in Havana, Cuba, in the municipality of Boyeros. Born as a project of the Cuban Revolution called the "Future Project" which has two objectives: to computerize the country and develop the software industry to contribute to economic development the same. It is the first Cuban university to be established under the purposes of the Battle of Ideas. Wikipedia.

Information security management is a very complex task which involves the implementation and monitoring of more than 130 security controls. To achieve greater efficiency in this process it is necessary to automate as many controls as possible. This paper provides an analysis of how many controls can be automated, based on the standards ISO 27001 and NIST SP800-53. Furthermore, we take the automation potential of controls included in the Consensus Audit Guidelines into account. Finally, we provide an overview of security applications that support automation in the operation of information security controls to increase the efficiency of information security management. © 2011 IEEE.

In this paper we design a new distributed genetic algorithm, which is able to self-adapt the value of one of the most important parameter in this kind of techniques using the information provided by theoretical models. We study different alternative ways to use the mathematical results in our genetic algorithm. We test our technique on a wide set of instances of the well-known MAX-SAT problem. Experiments show that our self-* proposal is able to obtain similar, or even better, results when it is compared to traditional algorithms whose setting is made by hand. We also show the benefits in terms of saving time and complexity of migration policy settings for distributed genetic algorithms without reducing their efficiency. © 2013 IEEE. Source

Present paper appeared as part of cooperation existing between the Information Sciences University and the Center of Molecular Immunology. The aim was to develop a procedure contributing to storage and analysis of clinical trials and to integral application of business intelligence service in this activity. A procedure proposal was made to manage the development of solutions in business intelligence in our center. Procedure was assessed from the method of the Delphi expert method obtaining a result qualified as very appropriate. Implementation of this procedure will allows storing all information managed in an integral and standard way, thus achieving to make viable the statistic analyses needed to be performed by the specialists of the institution.

A computational molecular dynamics study about structural, vibrational, and dynamical properties of water adsorbed in AFI zeolite types, AlPO 4-5, using a newly extended potential model and its all-silica isomorph, SSZ-24, is reported. The investigation was performed at different temperatures and for different water coverage (loading). The results of our molecular dynamics simulations allow a better comprehension of the water's properties in these zeolites. The computed structural data agree very well with the experiments for AlPO 4-5, reproducing the presence of helicoidal chains of the adsorbed water molecules, but predict a different arrangement of water molecules for SSZ-24, namely linear chains running along the channel axis. The diffusion coefficient of water at different loadings and temperature for both AlPO 4-5 and SSZ-24 were computed. According to our results in the temperature range 230-300 K, the diffusivity at the highest considered loading is 1 order of magnitude smaller than in bulk water, in essential agreement with the experiment. The results of our molecular dynamics simulations allow a better comprehension of the water's properties in these zeolites. © 2012 American Chemical Society. Source

In order to study the behaviour of water adsorbed in zeolites, which are microporous crystalline aluminosilicates, whose channels and cavities of nanometric dimensions can host many different molecules, we developed a sophisticated empirical potential for water, including the full flexibility of the molecule and the correct response to the electric field generated by the cations and by the charged atoms of the aluminosilicate framework. The reproduction of experimental data by our potential model is similar or even better than that obtained from the first principles methods. The results of molecular dynamics simulations of water confined in a variety of zeolites (worm-like clusters in silicalite, spherical nanoclusters in zeolite A and ice-like nanotubes in AlPO4-5 and SSZ-24) at different temperatures and coverage (loading) are discussed in connection with the experimental data, whose overall good reproduction encourages the attempt of an atomic-scale description of structural and dynamical phenomena occurring in confined water, in particular in the supercooled regime. The results are also compared with simulations and experimental data on bulk water. © 2010 IOP Publishing Ltd. Source
