El objetivo central de esta línea de investigación consiste en proponer distintas metodologías formales para representar el conocimiento en diversos sistemas argumentativos.
Como todo sistema simbólico, los sistemas argumentativos emulan el proceso de razonamiento como una manipulación dediversos símbolos. Esto…

Well-known methods for solving the shape-from-shading problem require knowledge of the reflectance map. Here we show how the shape-from-shading problem can be solved when the reflectance map is not available, but is known to have a given form with some…

In this paper, we test a version of the conditional CAPM with respect to a local market portfolio, proxied by the Brazilian stock index during the 1976-1992 period. We also test a conditional APT model by using the difference between…

(cont.) In this blurred area, a project/group-based curriculum can be developed to involve casual work areas that can fluctuate in size, based on the specifications of the project. Through the cultivation of this type of environment, the social energies of…

(cont.) Packing/Covering problems, we prove upper and lower bounds on the adaptivity gap depending on the dimension. We also design polynomial-time algorithms achieving near-optimal approximation guarantees with respect to the adaptive optimum. Finally, we prove complexity-theoretic results regarding optimal adaptive…

Context can be described as the totality of ideas, situations and information that (a) related to, (b) provide the origins for, and (c) influence our response, perspective or judgment of a thing. Design always takes place in a context. However,…

In the search for meaning, the architectural profession legitimately seeks culture to sanction its products. However, in business organizations, culture is complex and tacit- richer and deeper than any of its external manifestations, including architecture. To compensate for culture's incoherence,…

"The discrepancy between [our personal experiences] and our idealizations of knowledge leads us into counterproductive strategies for learning and thinking" (Papert 1993). This discrepancy has driven most research towards understanding how people fail to accomplish a task, while few researchers…

(cont.) in the ECS signal, no definitive method for sensing blade vibration using an ECS has yet been developed., High cycle fatigue (HCF) cracks generated by compressor blade vibrations are a common source of failure in gas turbine engines. Current…
