Estimation

A modular integrated probabilistic model of software reliability estimation and an algorithm of its application for estimation of software reliability with different architecture such as multilevel, multiversion, distributed and object-oriented ones are presented in the article. The modification of this model is given there for the object-oriented multiversion software with the distributed architecture. The procedure of its estimation is perfected to improve the quality of the reliability prediction. The description of the developed program system based on the modular integrated probabilistic model of reliability estimation of the object-oriented multiversion software with the distributed architecture is presented in the article. The analysis of relation of software reliability parameters to the component count, conditional and unconditional probability of the failure appearance in components and temporary components characteristics is done there as well

Highly Parallel Convolution Method to Compare DNA Sequences with Enforced In/Del and Mutation Tolerance

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.New error tolerant method for the comparison and analysis of symbol sequences is proposed. The method is based on convolution function calculation, where the function is defined over the binary numeric sequences obtained by the specific transformation of original symbol sequence. The method allows highly parallel implementation and is of great value for insertion/delition mutations search. To calculate the convolution function, fast Fourier transform is used in the method implementation. Предлагается новый устойчивый к ошибкам метод сравнения и анализа символьных последовательностей. Метод основан на вычислении функции свертки, где функция определяется над двоичными числовыми последовательностями, полученными путем конкретного преобразования исходной последовательности символов. Метод допускает эффективное распараллеливание и имеет большое значение для поиска мутаций вставки / удаления. Для вычисления функции свертки в реализации метода используется быстрое преобразование Фурье

Integrable Systems

Integrable systems which do not have an \u201cobvious\u201c group symmetry, beginning with the results of Poincar\ue9 and Bruns at the end of the last century, have been perceived as something exotic. The very insignificant list of such examples practically did not change until the 1960\u2019s. Although a number of fundamental methods of mathematical physics were based essentially on the perturbation-theory analysis of the simplest integrable examples, ideas about the structure of nontrivial integrable systems did not exert any real influence on the development of physics
