The results of tensile testing steel welded belts saw blades a linter machine are presented in the article. A universal was used to find stability gaskets machine. tests on study with thickness 1.5 mm and 2 using electric arc welding kemppi (a carbon dioxide technology) showed that order stretch up 5 mm, 2820 N is necessary for welding, 2900 kemppi; 3260 4440 welding. when gaskets, both can be ...

Intelligent nanomechanical devices that operate in an autonomous fashion are of great theoretical and practical interest. Recent successes in building large scale DNA nano-structures, in constructing DNA mechanical devices, and in DNA computing provide a solid foundation for the next step forward: designing autonomous DNA mechanical devices capable of arbitrarily complex behavior. One prototype...

Abstract In this work, a support vector machine (SVM) model was developed to predict the hot deformation flow curves of AZ91 magnesium alloy. The experimental stress-strain curves, obtained from hot compression testing at different deformation conditions, were sampled. Consequently, a data base with the input variables of the deformation temperature, strain rate and strain and the output variab...

According to the Algorithmic Coding Theorem, minimal programs of any universal machine are prefix-codes asymptotically optimal with respect to the machine algorithmic probabilities. A stronger version of this result will be proven for a class of machines, not necessarily universal, and any semi-distribution. Furthermore, minimal programs with respect to universal machines will be shown to be al...

introduction: the resistance to fracture of endodontically treated teeth restored with esthetic post systems has not been extensively researched. this in vitro study compared the fracture patterns of endodontically treated teeth with esthetic post systems with different analysis methods. materials and methods: a total of 26 recently extracted human maxillary central incisors were decoronated an...
