... In this case, the main vortex in the Benard cell is decomposed into smaller ones as a result of ten perioddoubling bifurcations. It is shown that the resulting turbulence is coherent and determinate; the fractal character (local selfsimilarity) of its spectrum is found. ... It is shown that the real atmospheric turbulence is the result of mixing of different coherent structures. ... COHERENT STRUCTURE IN A CLOSED ROOM The scheme of measurements in the LSVT spectrograph pavilion is shown in Fig. ...

... Характер изменения периода и амплитуды может служить основой дополнительной классификации всех полуправильных переменных звзд, поэтому информация об изменении периодов у каждой конкретной звезды является ценным научным результатом. Звезду S Per наблюдают астрономы-любители, что дат возможность получить кривую блеска за продолжительный период времени и изучить изменения амплитуды и периода. ... Период у этой звезды изменяется более чем в 2 раза, изменения периода хаотические с большим разбросом. ...
