We propose a competitive shared evaluation task for Surface Realization in Spanish. The task would be carried out in 2012. It would involve the generation of text in Spanish from a common ground input shared by all systems. Separate corpora for training/development (composed of pairs of common ground input and expected string result) and testing (only common ground input) will be provided. Auto...

Most of the current Machine Translation systems are designed to translate a document sentence by sentence ignoring discourse information and producing incoherencies in the final translations. In this paper we present some documentlevel-oriented post-processes to improve translations’ coherence and consistency. Incoherences are detected and new partial translations are proposed. The work focuses...

The outputs of computational creativity systems need to be evaluated in order to gain insight into the creative process. Automatic evaluation is a useful technique in this respect because it allows for a large number of tests to be carried out on a system in a uniform and objective way, and produce reports of its behaviour. Furthermore, it provides insights about an essential aspect of the crea...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

An intermediate frequency (IF) variable gain amplifier (VGA) with exponential gain control for a radio receiver is fabricated in 0.25-μm CMOS technology. The techniques to improve the bandwidth and to reduce temperature dependence of gain are described. The complete VGA is composed of two stages of linearized transconductance VGA and three stages of fixed gain amplifier (FGA). The complete VGA ...

Contrast adaptation that was limited to a small region of the peripheral retina was induced as observers viewed a multiple depth-plane textured surface. The small region undergoing contrast adaptation was present only in one depth-plane to determine whether contrast gain-control is depth-dependent. After adaptation, observers performed a contrast-matching task in both the adapted and a non-adap...

In the early years of radio circuits, fading (defined as slow variations in the amplitude of the received signals) required continuing adjustments in the receiver's gain in order to maintain a relative constant output signal. Such situation led to the design of circuits, which primary ideal function was to maintain a constant signal level at the output, regardless of the signal's variations at ...
