Chroma representations of musical excerpts are nowadays very popular and used for a wide variety of applications. Within these, transposition to a common key or tonality can represent an important aspect, usually having a dramatic impact to final system’s accuracy. We present and evaluate a new and straightforward way for transposing two chroma representations to a common key that outperforms p...

This paper describes a scheme for representing heterogeneous array circuits, in particular those which have been optimized by pipelining or by transposition. Equations for correctness-preserving transformations of these parametric representations are presented. The method is illustrated on developing novel pipelined designs for parallel division. It is estimated that, for a field-programmable g...

Residual insertion sequence elements (IS elements) in Escherichia coli strains that are commonly used for DNA cloning are known to cause cloning artifacts by transposing themselves into the recombinant DNA fragments. In such cases, chance insertion of IS elements may occur at integration sites in the cloning targets, which in the case of the IS10 element is a 9-bp consensus sequence. We report ...

We present genetic evidence that the tetracycline resistance element Tn10 transposes by a nonreplicative mechanism. Heteroduplex Tn10 elements containing three single base pair mismatches were constructed on lambda phage genomes and allowed to transpose from lambda into the bacterial chromosome. Analysis of TetR colonies resulting from such transpositions suggests that information from both str...

Enzyme loci located on chromosome J and U were mapped cytologically by means of a Y translocation technique. A linkage map of the two chromosomes was established in a parallel experiment and the recombination frequency in different regions of the chromosomes determined. A comparison of the cytogenetic localization of the enzyme genes in D. subobscura and D. melanogaster indicates that many para...

With the increasing popularity of the use of compressed images, an intuitive approach for lowering computational complexity towards a practically efficient image retrieval system is to propose a scheme that is able to perform retrieval computation directly in the compressed domain. In this paper, we investigate the use of energy histograms of the low frequency DCT coefficients as features for t...

The singing synthesis system we present generates a performance of an artificial singer out of the musical score and the phonetic transcription of a song using a frame-based frequency domain technique. This performance mimics the real singing of a singer that has been previously recorded, analyzed and stored in a database. To synthesize such performance the systems concatenates a set of element...

Here X is a vector of variables, all lying in the set S. The cost vector is denoted c. A is a matrix, b a vector, and together they form the constraints on the variables. When S is the set of real numbers, the mathematical model is said to be a linear program (LP). If S is a binary set or the set of integers, the problem is an integer program (IP). If some variables in X belong to the set of re...

This paper proposes a real-time variable-Q non-stationary Gabor transform (VQ-NSGT) system for speech pitch shifting. The system allows for time-frequency representations of speech on variable-Q (VQ) with perfect reconstruction and computational efficiency. The proposed VQ-NSGT phase vocoder can be used for pitch shifting by simple frequency translation (transposing partials along the frequency...
