In this paper we introduce a multi agent de-ontic update semantics, that builds on a logic of prescriptive obligations (norms) and a logic of descriptive obligations (normative propositions). In this preference-based logic we formalize rights as a new type of strong prescriptive permissions and duties and commitments as prescriptive obligations between agents. 1 Introduction In groups of agents...

The Problem: The idea of ubiquitous a computing environment where sensors and devices exist everywhere around us has opened up interesting security and privacy issues. Imagine a scenario in which Ben is working in an intelligent room. He does not want to be disturbed by anyone, so he tells the intelligent room that he does not want to be reached by anyone in the next two hours unless it is an e...

Royal Infirmary. A saturated solution of camphor in strong carbolic acid has long been known; but has attracted little notice as a therapeutic agent. Dr. Cochran,* of Shomond, Wis., has recommended its use, both locally and internally, as an antiseptic agent. He gives it internally in ten-drop doses in capsule, and injects it hypodermically; he also employs it externally. The camphor is dissolv...

Querying a database via different kinds of Internet and Intranet access is generally a repetitive and time-consuming task. QueryGuesser is an intelligent agent with the capability of generating personalized queries to a database system, according to a particular user’s interests. This agent observes a user behavior while he is querying a database and builds a model of his preferences with the i...

The three notions studied here are Bayesian priors, invariant priors and introspection. A prior for an agent is Bayesian, if it agrees with the agent’s posterior beliefs when conditioned on them. A prior is invariant, if it is the average, with respect to itself, of the posterior beliefs. Finally, an agent is introspective, if he is certain of his own beliefs. We show that a prior is Bayesian, ...

Sulphur Mustard is a potent chemical warfare agent that was widely used during first world war and Iran ‌Iraq conflict. Over 100,000 Iranians were injured by sulphur mustard and one-third is of them were suffering from late effects until today. This vesicant agent has a lot of acute and chronic destructive effects on the skin, eye and respiratory system. Sulphur mustard via the alkylations of s...

* 0-7803-7952-7/03/$17.00  2003 IEEE. Abstract – Intelligent Tutoring Systems are meant to provide individualised tutoring to students by adapting the teaching material to their specific needs and abilities. However, their development is a hard task and the endresult is difficult to evaluate. In this paper we present a novel approach for the evaluation of these systems, which relies on an agen...
