Elements of the history, state of the art, and probable future of Machine Translation (MT) are discussed. The treatment is largely tutorial, based on the assumption that this audience is, for the most part, ignorant of matters pertaining to translation in general, and MT in particular. The paper covers some of the major MT R&D groups, the general techniques they employ(ed), and the roles they p...

The topic of photo-equality in hardcopy technologies has been widely discussed from the beginning of digital printing until today. Photographic quality prints can be made on desk-top printers with little compromises in permanence and performance. The paper compares the status of ink-jet prints in professional and desktop systems with commercial photography. The gamut of typical ink-jet dye and ...

Motion information can form the basis of predictions about time-toimpact and the trajectories of objects moving through a scene. Firstly, a model that incorporates accumulative computation and lateral interaction is presented. By means of the lateral interaction in accumulative computation (LIAC) of each element with its neighbours, the model is able to segment moving objects present in an inde...

The number of studies on lizard ecology has increased greatly since 1960 (Huey et al. 1983), improving our knowledge on the evolution of life history characteristics, one of the most important tools for understanding the diversity Abstract The demography of the lizard Tropidurus torquatus (Squamata, Tropiduridae) in a highly seasonal Neotropical savanna. The demography of a population of Tropid...

Recommended by Jianshe Yu The permanence and the existence of periodic solution for a discrete nonautonomous competitive system with multidelays are considered. Also the stability of the periodic solution is discussed. Numerical examples are given to confirm the theoretical results.

We consider Banach space properties that lie between conditions introduced by Bynum and Landes. These properties depend on the metric behavior of weakly convergent sequences. We also investigate the permanence properties of these conditions.

Manual search for totally occluded objects was investigated in 10-, 12- and 14-month-old infants. Infants responded to two types of total hiding in different ways, supporting the inference that object permanence is not a once-and-for-all attainment. Occlusion of an object by movement of a screen over it was solved at an earlier age than occlusion in which an object was carried under the screen....
