The Savitzky–Golay (SG) filter design problem is posed as the minimum norm solution of an underdetermined equation system. A unified SG filter design framework encompassing several important applications such as smoothing, differentiation, integration and fractional delay is developed. In addition to the generality and flexibility of the framework, an efficient SG filter implementation structur...

The q-deformed supersymmetric t-J model on a semi-infinite lattice is diagonalized by using the level-one vertex operators of the quantum affine superalgebra Uq[ ̂ sl(2|1)]. We give the bosonization of the boundary states. We give an integral expression of the correlation functions of the boundary model, and derive the difference equations which they satisfy.

Research into the industrial application of formal methods has concentrated almost exclusively on the speci cation of software systems in high-risk or safety critical applications Thus, attention has been directed to technical problems with technical systems. In this paper we justify and report early results from a research project which aims to evaluate the implications of using the formal spe...

Complementary sequences were introduced by Marcel Golay [1] in the context of infrared spectrometry. A complementary pair of sequences (CS pair) satis£es the useful property that their out-of-phase aperiodic autocorrelation coef£cients sum to zero [1, 2]. Let a = (a0, a1, . . . , aN−1) be a sequence of length N such that ai ∈ {+1,−1} (we say that a is bi-polar). De£ne the Aperiodic Auto-Correla...

World population and the number of cultural artifacts are growing exponentially or faster, while cultural interaction approaches the fidelity of a global nervous system. Every day hundreds of millions of images are loaded into social networks by users all over the world. As this myriad of new artifacts veils the view into the past, like city lights covering the night sky, it is easy to forget t...

The Savitzky–Golay (SG) filters are generally used for smoothing and differentiation in many fields. The properties of the SG smoothing filters have been well studied. However, the properties of the SG differentiation filters or SG digital differentiators (SGDD, for the first order differentiation) are not developed well somehow, although they have been widely used. In the paper, the properties...

The idea that a new generation of students is entering the education system has excited recent attention amongst educators and education commentators. Termed ‘digital natives’ or the ‘Net generation’, these young people are said to have been immersed in technology all their lives, imbuing them with sophisticated technical skills and learning preferences for which traditional education is unprep...
