Periodic Oscillations in the Analysis of Algorithms and Their Cancellations
A large number of results in analysis of algorithms contain fluctuations. A typical result might read “The expected number of . . . for large n behaves like log2 n + constant + delta(log2 n), where delta(x) is a periodic function of period one and mean zero.” Examples include various trie parameters, approximate counting, probabilistic counting, radix exchange sort, leader election, skip lists,...
متن کاملPeriodic Oscillations in the Intra - day Optical Light Curves of the Blazar S 5 0716 + 714
We present results of a periodicity search of 20 intra-day variable optical light curves of the blazar S5 0716+714, selected from a database of 102 light curves spanning over three years. We use a wavelet analysis technique along with a randomization test and find strong candidates for nearly periodic variations in eight light curves, with probabilities ranging from 95% to >99%. This is the fir...
متن کاملA Quasi-Periodic Modulation of the Radio Light Curve of the Blazar PKSB0048−097
In this letter we present the results of a wavelet analysis of the radio light curve of the BLLac Object PKSB0048−097 from the University of Michigan Radio Astronomy Observatory monitoring program at 8GHz during twenty-five years, from 1979 to 2004. The results show a remarkable periodicity of 450–470 days in the early 1980s that changed to a ∼585 day periodicity in the late 1980s to early 1990...
متن کاملThe Harmonic and Sideband Structure of the Kilohertz Quasi-Periodic Oscillations in Sco X-1
We use data from the Rossi X-ray Timing Explorer to search for harmonics and sidebands of the two simultaneous kilohertz quasi-periodic oscillations (kHz QPOs) in Sco X-1. We do not detect any of these harmonics or sidebands, with 95% confidence upper limits to their power between ∼ 1% and ∼ 10% of the power of the upper kHz QPO. The oscillations produced at these frequencies may be attenuated ...
متن کاملPeriodic Variabilities in the Iue Spectra of Ss Cygni
The analysis of the IUE low resolution spectra of SS Cyg in quiescence clearly shows modulations with the orbital phase of the continuum and the emission lines total area. The shape of such modulations is depending on the type of the optical outburst preceding the quiescent phase in which the UV spectra were collected. This behaviour, together with those in other wavelength regions, could be ex...
