The expanded edition of Perceptrons (MIT Press, Cambridge, Mass, 1988, 292 pp , $12.50) by Marvin L. Minsky and Seymour A. Papert comes at a time of unprecedented interest in the biological and technological modeling of neural networks. One need only to refer to the August 1988 issue of AI Expert and Philip Chapnick’s editorial noting that more than 50 percent of the Fortune 500 companies are i...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
Computing the similarity between data elements is a basic functionality in flexible query answering systems. In the case of complex data definitions, for instance in terms of an ontology, computing the similarity between data elements becomes a non-trivial problem. In this paper, we propose a similarity measure for data described in terms of the DL-lite ontology language. In this measure, we ta...
This paper provides an introduction to measures of causal effects and focuses on underlying conceptual models, definitions and drawbacks of special relevance to policy formulation based on epidemiological data. It begins by describing a foundation for critical analysis based on counterfactuals and potential outcomes. It then describes analyses based on hypothetical outcome removal and rejects t...
Over the past ten years location-based services (LBS) have been variously touted as the next generation of GIS; as the killer application that will bring the GIS industry to its next level of prosperity; and as a growing threat to human privacy. This chapter attempts to provide a basic introduction to LBS, and a discussion of some of the major issues surrounding them. It begins with basic defin...
the neogene intrusion masses in the noudeh-enghelab area located to the north of sabzevar ophiolite have cut the late cretaceous ophiolitic rocks, sedimentary- volcanic and eocene volcanic rocks and have been covered by pliocene and quaternary deposits. the margin is of lava with basalt, phyric andesite-basalt and andesite and the central parts (dome shaped) composed of phyric andesite-trachyan...
This review serves as an introduction to the field of Artificial Chemistries, whose origins were derived from requirements in Artificial Life and its inspiration from Chemistry. The paper is divided in three sections, the first introducing important aspects for contextualizing the field and relating them to the classification criteria used at the last part. The next section begins with a defini...
as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...
during the third/ninth century, several commentators on euclid’s elements composed blocks of propositions (called ziyadat) in which they expanded specific concepts or techniques beyond the basic discussions of euclid. among the earliest of these ziy?d?t were three propositions created by al-‘abbas b. sa‘?d al-jawhar? in an attempt to demonstrate the validity of euclid’s definitions v, 5 and v, ...
