Elastic properties of 5d transition-metal carbides: An ab initio study

We have systematically studied the mechanical stability of group V transition metal carbides TMC$_2$ (TM = Hf, Ta, W, Re, Os, Ir, Pt, and Au) in the pyrite and fluorite phase, by calculating their elastic constants within the density functional theory scheme. It was found that all but ReC$_2$ and OsC$_2$ are stable in pyrite phase. On the other hand, all metal carbides studied were unstable in the fluorite phase.Comment: 7 pages, 4 figure

Using classifiers to predict linear feedback shift registers

Proceeding of: IEEE 35th International Carnahan Conference on Security Technology. October 16-19, 2001, LondonPreviously (J.C. Hernandez et al., 2000), some new ideas that justify the use of artificial intelligence techniques in cryptanalysis are presented. The main objective of that paper was to show that the theoretical next bit prediction problem can be transformed into a classification problem, and this classification problem could be solved with the aid of some AI algorithms. In particular, they showed how a well-known classifier called c4.5 could predict the next bit generated by a linear feedback shift register (LFSR, a widely used model of pseudorandom number generator) very efficiently and, most importantly, without any previous knowledge over the model used. The authors look for other classifiers, apart from c4.5, that could be useful in the prediction of LFSRs. We conclude that the selection of c4.5 by Hernandez et al. was adequate, because it shows the best accuracy of all the classifiers tested. However, we have found other classifiers that produce interesting results, and we suggest that these algorithms must be taken into account in the future when trying to predict more complex LFSR-based models. Finally, we show some other properties that make the c4.5 algorithm the best choice for this particular cryptanalytic problem.Publicad

IMPLEMENTASI KEBIJAKAN PENGEMBANGAN OBJEK WISATA SELAT LEMBEH KECAMATAN LEMBEH SELATAN KOTA BITUNG

The purpose of this study is to describe and analyze the implementation of the policy for the development of the Lembeh Strait tourism object, South Lembeh District, Bitung City. as well as to determine the factors supporting and inhibiting the implementation of the policy. The research method used in this study is a qualitative descriptive. Data collection techniques used are interviews, observations and documents The theory used is the Van Meter and Van Horn implementation model, the model consisting. The research informants were 15 people. The results showed that the implementation of the Lembeh Strait tourism object development policy, South Lembeh District, Bitung City has not been carried out properly due to the difficulty of establishing communication with the surrounding community in terms of cooperation in maintaining and supporting development facilities and the implementation of planned activities. In implementing this policy, human resources are still experiencing obstacles. Inadequate and ineffective coordination with other agencies is caused by the agency's own department, and the agency assumes itself that this development task is only the task of the related institutions.

Productivity of a \u3cem\u3eLeucaena Leucocephala-Cynodon Nlemfuensis\u3c/em\u3e Silvopastoral System with Sheep in Yucatan, Mexico

Animal production in the tropics of Mexico is based on grazed grasslands of low productivity; this type of production system has reduced the areas of natural vegetation and damaged the ecology (erosion of flora, fauna and soil). Silvopastoral technologies may improve the welfare and economic conditions of the rural population and, consequently, preserve their natural resources. The current work was designed to assess the introduction of Leucaena leucocephala in a silvopastoral system with Cynodon nlemfuensis (star grass) grazed by sheep
