Our experiments demonstrate that interference of an interpolated list of items with recall of an original list can be substantially reduced by forming Ss just before testing how to reorganize and simplify the interpolated material. In Experiments 1 and 2, Ss better recalled an initial serial list of letters when informed at testing that an interpolated list spelled a certain phrase backward. Si...

In this study, potential benefits of early memory testing were examined in terms of "inoculating" eyewitness memory against forgetting. As predicted by fuzzy trace theory (e.g., Reyna & Titcomb, 1997), a larger testing advantage in the delayed recall of event details was expected after immediate testing than after delayed testing because of the decline in accessibility of verbatim traces over t...

To reduce the artifacts due to color filter array (CFA) interpolation, a modified mean-removed classified vector quantization algorithm is proposed. The algorithm extends and modifies vector quantization to discover the relationships between the G channels of interpolated images and their corresponding original versions using the information from CFA images. The discovered relationships are sto...

We consider the minimization of hit error rate (BER) for OFDM systems with orthogonal precoders. For low S N Q we show that the conventional OFDM system is the optimal solution and the optimal precoder is the identity matrix. For high SNR, corresponding to a relatively practical range of BER, there are channel independent solutions for optimal precoders. One such solution is the DFT matrix and ...

We study the problem of finding unitary submatrices of the discrete Fourier transform matrix. This problem is related to a diverse set of questions on idempotents on ZN , tiling ZN , difference graphs and maximal cliques. Each of these is related to the problem of interpolating a discrete bandlimited signal using an orthogonal basis.

A sequence of auditory stimuli interpolated between the initial presentation of a tone and a comparison tone impairs recognition performance. Notably, the impairment is much less with interpolated speech than with tones. Six experiments converge on the conclusion that this pattern of impairment is due more to the organization of the interpolated sequence than to its similarity to the to-be-reme...

The binomial interpolated transform of a sequence is a generalization of the wellknown binomial transform. We examine a Pascal-like triangle, on which a binomial interpolated transform works between the left and right diagonals, focusing on binary recurrences. We give the sums of the elements in rows and in rising diagonals, and we define two special classes of these arithmetical triangles.
