Mining Multiple Periodic Time Series for Detecting Unusual Sub-Sequences
2009 Fourth International Conference on Innovative Computing, Information and Control (ICICIC), 2009Advances in computer and information technology have opened a new avenue in the analysis of large and more detailed datasets that has become possible to observe. Most of the classical methodologies and techniques have become obsolete and fresh approaches of data analysis are overdue.

The authors characterize the structure and geometry of maximal sets of unbounded divergence and maximal sets of convergence almost everywhere of multiple Fourier series with a \(J_{k}\)-lacunary sequence of rectangular partial sums \(S_{n^{\left( \alpha \right) }\left[ J_{k}\right] }\left( x;f\right) \) for functions \(f\in L_{p}\left( T^{N}\right)\), \

296 We investigate the equiconvergence onN = (-π, π) N of expansions in multiple trigonometric Fourier series and Fourier integrals of functions f ∈ Lp( N ) and g ∈ L p ( N ), p > 1, N ≥ 2, g(x )= f (x) onN , in the case when the "partial sums" of these expansions, i.e., Sn(x; f ) and Jα(x; g), respectively, have "indices" n =( n1, n2, …, nN) ∈ N ...

THE TENSOR BMO-PROPERTY OF THE SEQUENCE OF PARTIAL SUMS OF A MULTIPLE FOURIER SERIES
Russian Academy of Sciences. Sbornik Mathematics, 1995In order to shorten notations, we present the results in the two- dimensional case. Denote by \(S_k(f, x)\) the rectangular partial sums of the double Fourier series of a function \(f\in L(T^2)\), \(k= (k_1, k_2)\), and \(x= (x_1, x_2)\). The author proved in Mat. Zametki 50, No. 1, 148-150 (1991; Zbl 0781.42013) that the operator \[ T_1 f(x):= \sup_{m\
