A study of Apparent Motion (AM) of Gamma type is presented which extends previous findings (Geissler, Schebera & Kompass 1999) showing that a temporal parameter (ISI), critical for the perceptual transition AM -> flicker, exhibits discrete timing. The major empirical results, a set of four significant ISI modal values, having integer size ratios 3 : 4 : 6 : 8, and a regularity in the spacing of...
Abstract Intra-individual processes are thought to continuously unfold across time. For equally spaced time intervals, the discrete-time lag-1 vector autoregressive (VAR(1)) model and continuous-time Ornstein–Uhlenbeck (OU) equivalent. It is expected that by taking into account unequal spacings of intervals in real data between observations will lead an advantage for OU terms predictive accurac...
Meteorological data mining aims to discover hidden patterns in a large number of available meteorological data. As one the most relevant big preprocessing technologies, feature discretization can transform continuous features into discrete ones improve efficiency algorithms. Aiming at problems high interaction multiple attributes, noise interference, and difficulty obtaining prior knowledge dat...
For an interval graph with some additional order constraints between pairs of non-intersecting intervals, we give a linear time algorithm to determine if there exists a realization which respects the order constraints. Previous algorithms for this problem (known also as seriation with side constraints) required quadratic time. This problem contains as subproblems interval graph and interval ord...
In the present work we examine both the linear and nonlinear properties of two related parity-time (PT)-symmetric systems of the discrete nonlinear Schrödinger (dNLS) type. First, we examine the parameter range for which the finite PT-dNLS chains have real eigenvalues and PT-symmetric linear eigenstates. We develop a systematic way of analyzing the nonlinear stationary states with the implicit ...
Let G be an arbitrary cyclic group with generator g and order jGj with known factorization. G could be the subgroup generated by g within a larger group H. Based on an assumption about the existence of smooth numbers in short intervals, we prove that breaking the Diie-Hellman protocol for G and base g is equivalent to computing discrete logarithms in G to the base g when a certain side informat...
