We introduce the Banach space S0 âŠ† L 2 which has a variety of properties making it a useful tool in Gabor analysis. S0 can be characterized as the smallest time-frequency homogeneous Banach space ofâ€¦ (More)

A study was conducted to evaluate the activity of a single administration of doramectin or ivermectin against severe, induced infestations of Cochliomyia hominivorax. Twenty-four Holstein bull calvesâ€¦ (More)

The problem of automatic description of a natural scene is usually divided into two steps: (1) constructing an abstract propositional description of the scene a task carried out by a vision system,â€¦ (More)

We characterize the Schwartz space of rapidly decaying test functions by the decay of the short-time Fourier transform or cross-Wigner distribution. Then we prove a version of Hardyâ€™s theorem for theâ€¦ (More)

We study convergent scalar d-variate subdivision schemes satisfying sum rules of order k âˆˆ N, with dilation matrix 2I . Using the results of MÃ¶ller and Sauer in [18], stated for general expandingâ€¦ (More)

Although image understanding and natural language processing constitute two major areas of AI, they have mostly been studied independently of each other. Only a few attempts have been concerned withâ€¦ (More)

In this paper we compare different transmultiplexer structures with respect to the ISI/ICI occuring for typical timeâ€“invariant channels. In particular we consider waveletâ€“type, Gabor-type (the classâ€¦ (More)

The concept of stationary scalar subdivision being interpolatory does not always extend immediately to the vector valued case. We introduce the concepts of interpolating and data preserving vectorâ€¦ (More)
