In this article, a fast algorithm is developed to compute two-dimensional convolutions of an array of d 1· d 2 complex number points, where d 2 = 2 and d 1 = 2m -r+ 1 for some I ,.; r ,.; m. This new algorithm requires fewer multiplications and about the same number of additions as the conventional FFT method for computing the two-dimensional convolution. It also has the advantage that the oper...

Pror.*^ ? ns' interposition operation for prolapse ?aentia. The principle of the Watkins' operation is based on separating the bladder from the anterior wall of the nterus and transposing its attachment to the posterior wall, so that the uterus is left in a position to support the entire bladder. Watkins performed his first operation in 1898. Several modifications, notably that of Wertheim, hav...

A high speed and reduced-area 2-D discrete wavelet transform (2-D DWT) architecture is proposed and the design is simulated. Initially modifications are made to the lifting scheme, and the intermediate results are recombined and stored to reduce the number of pipelining stages. The architecture uses three basic 1D-DWT image processing elements. The proposed architecture only requires less regis...

Functional transposition is a technique for converting relations into functions aimed at developing the relational algebra via the algebra of functions. This paper attempts to develop a basis for generic transposition. Two instances of this construction are considered, one applicable to any relation and the other applicable to simple relations only. Our illustration of the usefulness of the gen...

Currently, the only behind-the-ear hearing aid that provides a frequency transposition function is the ImpaCt DSR675, recently introduced by AVR Communications Ltd. of Israel. In tests with three hearing-impaired adults, the performance of the ImpaCt aid(s) was compared with that of each subject's own (nontransposing) hearing aids. Recognition of monosyllabic words and medial consonants did not...

Since the human genome sequences became available in 2001, our knowledge about the human transposable elements which comprise ∼40% of the total nucleotides has been expanding. Non-long terminal repeat (non-LTR) retrotransposons are actively transposing in the present-day human genome, and have been found to cause ∼100 identified clinical cases of varied disorders. In contrast, almost all of the...

Nonwords created by transposing two letters (e.g., RELOVUTION) are very effective at activating the lexical representation of their base words (Perea & Lupker, 2004). In the present study, we examined whether the nature of transposed-letter (TL) similarity effects was purely orthographic or whether it could also have a phonological component. Specifically, we examined transposed-letter similari...

One key issue for any computational model of visual word recognition is the choice of an input coding scheme for assigning letter position. Recent research has shown that transposed-letter similarity effects occur even when the transposed letters are not adjacent (caniso-casino; Perea & Lupker, 2004, JML). In the present study we conducted two single-presentation lexical decision experiments to...
