The prey-predator pursuit problem is referenced many times in literature. It is a generic multi-agent problem whose solutions could by applied to many particular instances. Solutions proposed usually apply non-supervised learning algorithms to train prey and predators. Most of these…

Spanish conquistador Álvar Núñez Cabeza de Vaca and British explorer John Smith went to the New World for different reasons but both shared the experience of being a captive to the Native Americans. After their return to Europe, both of…

This article explores the way in which text worlds are created in advertising discourse by analysing linguistic choices and features of context which are crucial in the determination of specific relations between sender(s) and target audience(s), in particular, deixis and…

The use of computer programs that can be used to correct and assess students' written work in the EFL classroom has become more commonplace within the last decade. This paper discusses the role of CALL in the process of data…

Although there is a general understanding of Montagu’s harrier migration routes and wintering areas, detailed information on the species’ migration is still lacking. However, improvements in satellite tracking technology in recent years have enabled the study of medium-sized species by…

Design and optimization of distillation columns for ethanol dehydration, using a hydrocarbon as entrainer, implies a good knowledge of vapor-liquid (VLE), liquid-liquid (LLE) and vapor-liquid-liquid equilibrium (VLLE). Chemical process simulation programs always require the use of a thermodynamic model that…

The Millennium Development Goals (MDG) progress targets have not been met. Nevertheless, the United Nations (UN) has not yet undertaken in-depth review in order to discover the reasons behind this lack of progress in achieving the MDG. From a political…

In this paper a cross-disciplinary study of the use of epistemic markers as hedging rhetorical strategies in research articles in English is carried out. Based on computer readable data, and combining quantitative and
qualitative methods, the article argues that the…

The chemical effects of acoustic cavitation are obtained in sono-reactors built-up from a vessel and an ultrasonic
source. In this paper, simulations of an existing sono-reactor are carried out, using a linear acoustics model, accounting
for the vibrations of the…

Web-based learning environments are becoming increasingly popular in higher education. One of the most important web-learning resources is the virtual laboratory (VL), which gives students an easy way for training and learning through the Internet. Moreover, on-line collaborative communication represents…
