This paper presents a proposal enabling the modelling of manufacturing processes independently of the structure and composition of the industrial plant where these processes will ultimately be implemented. The rationale for the proposal is in the incorporation of knowledge, supported…

Caballerolecythus ibunami n. gen., n. sp. is described from the intestine of 2 species of rodents (Liomys irroratus [Gray, 1868] and Peromyscus difficilis [Allen, 1891]) from Piñonal, El Carmen Tequexquitla, Tlaxcala state, Mexico. These specimens represent a new genus and…

Performance and manufacturability are two important issues that must be taken into account during MEMS design. Existing MEMS design models or systems follow a process-driven design paradigm, that is, design starts from the specification of process sequence or the customization…

Desde el punto de vista de la conservación, conocer la abundancia, la diversidad, y los patrones de actividad de un ensamble herpetológico son medulares para comprender la dinámica de la comunidad y el modo de cómo es utilizado el hábitat.…

Does knowledge of language consist of symbolic rules? How do children learn and use their linguistic knowledge? To elucidate these questions, we present a computational model that acquires phonological knowledge from a corpus of common English nouns and verbs. In…

This paper introduces a model of spatial cognition to describe the states of partial knowledge that people have about the spatial structure of a large-scale environment. Spatial knowledge has several different representations, each of which captures one aspect of the…

Effective document retrieval using domain knowledge and semantics is one of the major challenges in Information Retrieval. Over the last years, there has been a growing interest in ontologies as an artifact for human knowledge representation and a critical component…
