This paper concerns the experimental validation of the near-field – far-field transformation technique with helicoidal scanning. Such a technique, based on the theoretical results concerning the nonredundant sampling representations of the electromagnetic fields, makes use of a two-dimensional optimal sampling interpolation formula to reconstruct the near-field data needed to perform the classi...

This paper introduces a fast image mosaicing technique that does not require costly search on image domain (e.g., pixel-to-pixel correspondence search on the image domain) and the iterative optimization (e.g., gradient-based optimization, iterative optimization, and random optimization) of geometric transformation parameter. The proposed technique is organized in a two-step manner. At both step...

DNA-mediated transformation is a powerful tool that allows the introduction of specific genetic changes in an organism. Transformation of Aspergilli, acclaimed for their wide use in the industry, has been possible for about two decades now. Several basic and applied problems related to fungal biology have been addressed using this technique. Nonetheless, new markers and strategies for transform...

In this paper, we propose a new model-order reduction technique for linear dynamic systems. The idea behind this technique is to transform the dynamic system function from the s-domain into the z-domain via the bilinear transformation, then use Prony’s [1, 2] or Shank’s [3] least-squares approximation methods instead of the commonly employed Padé approximation method, and finally transform the ...

This paper consists of a survey of current, and past, work on program transformation for the purpose of optimization. We first discuss some of the general methodological frameworks for program modification, such as analogy, explanation based learning, partial evaluation, proof theoretic optimization, and the unfold/fold technique. These frameworks are not mutually exclusive, and the latter, unf...

Spectral modeling synthesis (SMS) is a powerful tool for musical sound modeling. This technique considers a sound as a combination of a deterministic plus a stochastic component that makes possible for a synthesized sound to attain all the perceptual characteristics of the original sound. In this paper, we propose a modified SMS which includes a new transformation technique to synthesize the de...
