The Generic Frame Protocol (GFP) is an application program interface for accessing knowledge bases stored in frame knowledge representation systems (FRSs). GFP provides a uniform model of FRSs based on a common conceptualization of frames, slots, facets, and inheritance. GFP consists of a set of Common Lisp functions that provide a generic interface to underlying FRSs. This interface isolates a...

Uniform tight frames have been shown to be useful for robust data trans mission The losses in the network are modeled as erasures of transmitted frame coe cients We give the rst systematic study of the general class of uniform tight frames and their properties We search for e cient con structions of such frames We show that the only uniform tight frames with the group structure and one or two g...

Most feature extraction techniques involve in their primary stage a Discrete Fourier Transform (DFT) of consecutive, short, overlapping windows. The spectral resolution of the DFT representation is uniform and is given by Δf=2π/Ν where N is the length of the window The present paper investigates the use of non-uniform rate frequency sampling, varying as a function of the spectral characteristic...

A tuned mass rocking wall (TMRW)-frame structure system is proposed to improve the energy dissipation ability of traditional wall-frame system. Based on principle damper (TMD), a TMRW designed with proper and stiffness according dynamic characteristic host structure. Firstly, considering presence inherent structural damping, amplification factor main was derived from equations mechanism. practi...

In this paper, we study the performance of the PCM scheme with linear quantization rule for quantizing finite unit-norm tight frame expansions for R and derive the PCM quantization error without the White Noise Hypothesis. We prove that for the class of unit norm tight frames derived from uniform frame paths the quantization error has an upper bound of O(δ) regardless of the frame redundancy. T...

The LPC prediction error provides one measure of the success of linear prediction analysis in modeling a speech signal. Although a great deal is known about the properties of the prediction errOr, relatively little has been published about its variation as a function of the position of the analysis frame. In this paper it is shown that a fairly substantial variation in the prediction error is o...

Nonuniform Fourier data are routinely collected in applications such as magnetic resonance imaging, synthetic aperture radar, and synthetic imaging in radio astronomy. To acquire a fast reconstruction that does not require an online inverse process, the non-uniform fast Fourier transform (NFFT), also called convolutional gridding, is frequently employed. While various investigations have led to...

Combined input-crosspoint buffered (CICB) switches relax arbitration timing and provide high-performance switching for packet switches with high-speed ports. It has been shown that these switches, with one-cell crosspoint buffer and round-robin arbitration at input and output ports, provide 100% throughput under uniform traffic. However, under admissible traffic patterns with nonuniform distrib...
