В серии компьютерных экспериментов на основе программ расчета групп симметрии при изучении струк-тур с нарушенной симметрией обнаружены новые множества с «нулем», «единицей», без обратных элементов, с конвергентными (сходимостью) и дивергентными (расходимостью) свойствами орграфа структуры. В работе продемонстрированно, что существует возможность перехода от множества преобразований с конвергентны-ми свойствами орграфа структуры к структурам множеств с дивергентными свойствами заменой некласси-ческих матриц с нарушенной симметрией на обратные матрицы подстановок. А также показана конкретная корреляция этих свойств с моделями накопления и послойного роста, используемыми в нанокластерном ана-лизе, радиотехнике, при математическом описании состояний некоторых экономических систем и объектов кристаллохимии, что является наглядной демонстрацией принципа «диссимметрии» П. Кюри. A.G. and N.G. Stoletovs, Vladimir, e-mail: godograf@list.ru In computer simulations, by studying the tables, sets of binary transformations with broken symmetry we've discovered the new sets with «zero» and «one» without inverse elements, with convergent and divergent properties of structure's oriented graphs. It is possible to continue from a variety of transformations with convergent properties of oriented graphs' structure to the structure of the set with divergent properties. A correlation of these properties with the accumulation models and the layer growth used in the analysis of the nanoclusters, radio technique, as well as the description of the conditions of some economic systems and the chemistry of crystals. This is a clear demonstration of the principle of «dissymmetry» pierre Curie.
To increase the noise immunity of signal transmission, diversity methods are now widely used, consisting in obtaining and combining several copies of the transmitted signal. In this case, it is possible to perform a combination either before the detection procedure or after it. If you do not take into account the possible use of non-linear types of modulation, then the pre-detector combination always has advantages over the post-detector combination. However, taking into account the nonlinear properties of the transmitted signals, new possibilities appear for increasing the noise immunity in combination and simplifying the processing. In the case of using analog signals, in particular frequency modulation, at certain points in time, the pre-detection combination can lose to the post-detection combination. At the same time, by combining pre-detector and post-detector combining circuits, it is possible to lower the threshold level during demodulation and increase noise immunity. In the case of using digital modes of modulation, it is possible to process only the signals after demodulation without reducing the noise immunity and to eliminate the need for preliminary phasing of the diversity signals before detection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
