Biofouling is the colonization of man-made substrata by sessile organisms. The aim of this paper is to evaluate the performance of two antifouling saturated copper coating. Bioassays were can-ied out at a harbor in Argentine (38°02'S-57°32'W). During six months, one…

The genus Acroleucus Stål from México is revised. Two new species A. calvatus and A. tensus are described and illustrated. New distribution records are presented, as well as comments on the host plants for some of the species. A revised…

En los últimos años se ha elevado el número de personas que quieren aprender español como segunda lengua/lengua extranjera. Porello, es importante estudiar las dificultades que tienen que afrontar los estudiantes no nativos de español al momento de involucrarse en…

Several surveys have indicated that many data warehouses fail to meet business objectives or are outright failures. One reason for this is that requirement engineering is typically overlooked in real projects. This paper addresses data warehouse design from a business…

This paper describes an efficient implementation of multiple-target multiple-view tracking in video-surveillance sequences. It takes advantage of the capabilities of multiple core Central Processing Units (CPUs) and of graphical processing units under the Compute Unifie Device Arquitecture (CUDA) framework. The…

The general objective of this thesis is the development of an adaptive technique for extracting knowledge in large databases. Nowadays, technology allows storing huge volumes of information. For this reason, the availability of techniques that allow, as a first stage,…

In this paper the stability of specific quantum control protocols is analyzed through a simu­lation. Two-level quantum systems driven by resonant external fields are studied. The focus of attention are those protocols requiring long sequences of external pulses. It is…

This paper identifies and quantifies through a Bayesian Network model (BN) the various factors of Operational Risk (OR) associated with the payment process PROCAMPO. The BN model is calibrated with data from events that occurred during the period 2008-2011. Unlike…

AbstractThe important role of new technologies to communicate in the globalized world we live in cannot be denied. Teachers must take this fact into account and help their students construct their knowledge through computer-mediated learning in order to better understand…
