This paper introduces a new parallel programming model for situated multi-agent systems simulations and its parallel library implementation on shared memory MIMD parallel computers. The first goal is to allow users to easily implement situated multi-agent systems, following their natural paradigm: concurrent agent behavior definition and environment update programming. The second goal is to obt...

DL-Lite is being regarded as an effective logic for ontology reasoning due both to its expressive power and its computational properties. Considering that ontologies are important constructs for multi-agent system, in this paper we propose the integration of ontology reasoning and agent-oriented programming. More specifically, we consider an agent-oriented programming language based on DL-Lite ...

Signature-based detection provides a relatively simple and efficient method for detecting known viruses. At present, most antivirus systems rely primarily on signature

nigella sativa seeds have wide therapeutic effects and have been reported to have significant effects against many ailments such as skin diseases, jaundice, gastrointestinal problems, anorexia, conjunctivitis, dyspepsia, rheumatism, diabetes, hypertension, intrinsic hemorrhage, paralysis, amenorrhea, anorexia, asthma, cough, bronchitis, headache, fever, influenza and eczema. thymoquinone (tq) i...

We propose novel algorithms for automatically determining a user’s profile from his/her content usage history (profiling agent), and automatically filtering content according to the user’s profile (filtering agent). A fuzzy inference system is used to construct and periodically update the preferences of a user based on the user’s interactions with various types of content over an observation pe...

Security fixes and feature improvements don’t benefit the end user of software if the update mechanism and strategy is not effective. In this paper we analyze the effectiveness of different Web browsers update mechanisms; from Google Chrome’s silent update mechanism to Opera’s update requiring a full re-installation. We use anonymized logs from Google’s world wide distributed Web servers. An an...

In this paper, event-triggered controllers and corresponding algorithms are proposed to establish the formation with connectivity preservation for multi-agent systems. Each agent needs to update its control input and to broadcast this control input together with the relative state information to its neighbors at its own triggering times, and to receive information at its neighbors’ triggering t...

A rational agent (artificial or otherwise) residing in a complex changing environment must gather information perceptually, update that information as the world changes, and combine that information with causal information to reason about the changing world. Using the system of defeasible reasoning that is incorporated into the OSCAR architecture for rational agents (Pollock 1995 and 1995a), a ...

We propose a model of an agent which is both logical and operational. Our model of vivid agents takes into account that agents need not only the ability to draw inferences but also to update their current knowledge state, to represent and to perform (and to simulate the execution of) actions in order to generate and execute plans, and to react and interact in response to perception and communic...

Abstract: In this paper, the problem of event-triggered consensus for linear continuous-time multi-agent systems is investigated. A new event-triggered consensus protocol based on a predictor is proposed to achieve consensus without continuous communication among agents. In the proposed consensus protocol, each agent only needs to monitor its states to determine its event-triggered instants. Wh...
