The thesis examines aspects of the construction of methylmercury as an authoritative object of knowledge for Chisasibi, a Cree community on the James Bay coast in northern Quebec. I describe the evolution of a particular set of spheres of exchange…

(cont.) to the verifier., We consider an implementation of a weakened notion of zero-knowledge (weak ZK) where the simulator is also allowed to depend on the distinguisher as well, so this type of ZK entails exhibiting an efficient simulator for…

There are many situations in which a very detailed low-level description encodes, through a hierarchical organization, a recognizable higher-order pattern. The macro-molecular structural conformations of proteins exhibit higher order regularities whose recognition is complicated by many factors. ARIADNE searches for…

Many systems have been developed for constructing decision trees from collections of examples. Although the decision trees generated by these methods are accurate and efficient, they often suffer the disadvantage of excessive complexity that can render them incomprehensible to experts.…

This thesis tries to bring together al-Ghazali's thoughts about different aspects of education, scattered in numbers of works of different kinds and aims at presenting his educational theory in its complete picture. His life, his intellectual career, his mental crises,…

Intelligent agents in the physical world must work from incomplete information due to partial knowledge and limited resources. An agent copes with these limitations by applying rules of conjecture to make reasonable assumptions about what is known. Circumscription, proposed by…
