摘要:ABSTRACT(#br)In this paper, we revisit the problem of testing of the hypothesis of circular symmetry of a bivariate distribution. We propose some nonparametric tests based on sector counts. These include tests based on chi-square goodness-of-fit test, the classical likelihoo...

摘要:...) statistic to test circular symmetry it is possible to obtain highly manageable expressions for the exact distribution of such statistic, when the number of variables, $$p$$ , is odd, and highly manageable and accurate approximations for an even $$p$$ . For the case of an eve...

摘要:... We propose a new algorithm, the Circular Symmetry algorithm (C-Sym), for detecting the position of a circular particle with high accuracy and precision in noisy conditions. The algorithm takes advantage of the spatial symmetry of the particle allowing for subpixel accuracy. W...

摘要:Abstract(#br)In this paper, the distribution of the likelihood ratio statistic for testing the hypothesis that the covariance matrix of a p -variate normal distribution is circular symmetric has been derived. The distribution is obtained in series form using the inverse Mellin tr...

摘要:...This model assumes the droplets are circular and spread according to a power law.This leads to a third-order nonlinear ordinary differential equation on[0,1] that gives the evolution of the height profile. We examine existenceof solutions for this equation.

摘要:... Assuming the droplets are circular weare able to prove existence of solutions with infinite contact angle and inmany cases we are able to prove nonexistence of solutions with finite contactangle.

摘要:Abstract(#br)The periodic mesoscale structures arranged in a circular symmetry were found at the silicon surface exposed to radiation of the single femtosecond laser pulse with a Gaussian intensity profile in the ambient air conditions. These peculiar structures have the appear...

摘要:Abstract(#br)We apply asymptotic methods of nonlinear mechanics (the Bogolyubov–Mitropol'skii averaging method) to the construction of approximate solutions of a system of nonlinear equations describing wave processes in elastic systems with circular symmetry. As an example,...

摘要:... In vacuum chambers with circular cross section, the dominant transverse wake driven by a leading particle and seen by a trailing test particle is dipolar and is proportional only to the transverse offset of the driving particle. The contributions of preceding bunches or previ...
