A short survey on nonlinear models of the classic Costas loop: rigorous derivation and limitations of the classic analysis

Rigorous nonlinear analysis of the physical model of Costas loop --- a classic phase-locked loop (PLL) based circuit for carrier recovery, is a challenging task. Thus for its analysis, simplified mathematical models and numerical simulation are widely used. In this work a short survey on nonlinear models of the BPSK Costas loop, used for pre-design and post-design analysis, is presented. Their rigorous derivation and limitations of classic analysis are discussed. It is shown that the use of simplified mathematical models, and the application of non rigorous methods of analysis (e.g., simulation and linearization) may lead to wrong conclusions concerning the performance of the Costas loop physical model.Comment: Accepted to American Control Conference (ACC) 2015 (Chicago, USA

Examination of evidence for collinear cluster tri-partition

In a series of the experiments at different time-of-flight spectrometers of heavy ions we have observed manifestations of a new at least ternary decay channel of low excited heavy nuclei. Due to specific features of the effect, it was called collinear cluster tri-partition (CCT). The experimental results obtained initiated a number of theoretical articles dedicated to different aspects of the CCT. We compare theoretical predictions with our experimental data, only partially published so far. The model of one of the most populated CCT modes that gives rise to the so called "Ni-bump" is discussed. Detection of the 68-72Ni fission fragments with a kinetic energy E<25 MeV at the mass-separator Lohengrin is proposed for an independent experimental verification of the CCT.Comment: 16 pages, 14 figure

Practice of spiritual-commercial movement as a phenomenon of the consumer society

Спиритуально-коммерческое движение один из ярчайших примеров влияния общества потребления на область религии, более того, влияния парадигмы потребления на духовную жизнь человека. Существует проблема атрибуции спиритуально-коммерческого движения как религиозного явления. На наш взгляд выведение его за рамки религиозного уводит нас от понимания духовных основ этого феномена. Ряд аспектов спиритуально-коммерческого движения рассматривается в статье: его религиозный характер, приверженность неклассической этике, связь с парадигмой потребления. В работе рассматривается возможность применения понятия потребительской идентичности, которое широко используется в маркетинговых исследованиях, для описания поведения людей входящих в СКД (участниц женских практик). Женские практики это практики, относящиеся к спиритуально-коммерческому движению, содержащие идеи религиозного характера, направленные на достижение "женственности". Результаты исследований ряда спиритуально-коммерческих движений Среднего Урала представлены в данной работе.Spiritual-commercial movement is one of the most striking examples of the impact of the consumer society on the sphere of religion. Moreover, it is the influence of the consumption paradigm on the spiritual life of man. There is a problem of attribution of the spiritual-commercial movement as a religious phenomenon. In our view moving it away from the realm of the religious leads us away from understanding the spiritual foundations of this phenomenon. Several aspects of spiritual-commercial movement are considered in this article: its religious character, commitment to non-classical ethics, and connection with the consumption. In this research discussed the possibility of applying the concept of consumer identity, which is widely used in marketing research, as a tool to describe the behavior of people why practice SCM (the women's practices participators). Women's practices are belonged to spiritually-commercial movement, contain religious ideas, help to achieve "femininity". The results of several studies of the spiritual-commercial movements of the Middle Urals are presented in this paper.Программа развития УрФУ на 2013 год (п.2.1.2.1
