Modeling resource management by agents interaction

A scenario is envisaged in which agents have tasks to perform and are in a position to exchange tasks to improve their performance, and thus perhaps affect the overall performance of the system. Our model uses two computing machines with their usual resources, and with random initial jobs to be processed. Their performance is dependent not only on absolute total load but also on how much of each machine's resources are in demand, thus giving scope for the beneficial exchange of jobs. This paper describes the development of a negotiation mechanism for job exchange between machines and measurement of system performance. The concept may be extended to multiple machines that act as agents exchanging resources and tasks.

An agent interaction model for performance enhancement of network system

WSEAS Transactions on computers 2005年第5期4卷 440-448页

We envisage a scenario where a system of network computer initially with random loads, exchange jobs to balance load among themselves to enhance their individual performance and to provide augmented quality of service (QoS) to the user community. We model the individual machines as agents interacting with one another. The agents have beliefs and aspirations. The aspiration of an agent is seek load from other, when it did not have enough to begin with, and sheds the same of it finds itself excessively loaded. This paper develops the concept with a design of a utility function to reflect the agent aspiration. We also propose a measure of load imbalance between networked machines. Negotiation mechanism is developed for exchange of jobs between agents. We report our result of the simulation with two machines and extend the same for three machines. The extension of the idea to a large number of machines entail coming to term with complexity in form of administrative overloads. We discuss the "small word" concept in the content of a simulation massively large number of machines interconnected.

One of the largest barriers to learning programming is the precise and complex syntax required to write programs. This barrier is a key impediment to the integration of programming into the core curriculum of general high school science courses - there is not enough time to learn both syntax and programming in a three-week course module. The newly developed "Iconic programmer" allows executable programs to be written through mouse clicks and menus, includes symbol by symbol translation into Java and Turing, and comes complete with a three-week lesson plan suitable to new programmers. To date, the new tool has been used effectively with full-semester, introductory programming courses at both the university and high school level. Copyright 2005 ACM.

Active learning enables learners to actively engage in learning. Learning not only transfers material to students for learning, but also encourages greater mental engagement and more extensive student-student and student-instructor interaction than does a typical lecture class. Peer Instruction (PI) engages students in active learning by achieving continuous instructor-student interaction in a physics lecture. However, the methodologies and the effectiveness of implementing PI for elementary school students have seldom been clarified. This study explores the possibility of adopting PI in an elementary science classroom. The research considerations of the study are as follows: (1) how wireless technology can enhance PI in elementary science classroom;(2) how a teacher can engage students in pre-class reading, and (3) whether elementary school students have sufficient social skills to perform a PI discussion? These questions are examined by observing how the PI pedagogical model worked with a wireless response system in elementary science classroom. Based on the observation, this study also proposes a way of improving the PI learning experience of elementary school students by adding experiments and observations during peer discussion to explain concepts and phenomena in physics. © 2005 IEEE.

Unsupervised knowledge navigation: Reconstructing the hypermedia structure of instructional materials on world wide web

WSEAS Transactions on information science and Applications 2005年第10期2卷 1505-1513页

There are many different terms when learner surf on web. When learner is reading an instructional material, he/she may not understand the meaning of specific term/keyword in a moment easily. At this time, the learner will need to find out the definitions or references about the keyword. However, unfortunately, the learner will not be able to find out what he/ she is looking for in the most of time. It is because of the instruction designers of the learning materials who had never thought that would be a problem for learners. Therefore, it will be excellent, if the associated documents with the keyword which is the learner looking for could be retrieved automatically, and furthermore, the original document structure could be reconstructed to a more suitable for learning and reading in real-time. In this paper, the graph theorem and the data mining technique are applying to produce an association lattice of keywords and design a searching algorithm of reconstructing the necessary instructional materials on the website automatically.

The purpose of this paper is to demonstrate the design and implementation of GISolve - a Grid-based problem solving environment for computationally intensive geographic information analysis based on geo-middleware. The geo-middleware resides between existing Grid middleware and geographic information analysis applications to manage heterogeneous and dynamic resources on behalf of analysis applications. At the same time, GISolve provides adaptive domain decomposition solutions to parallel geographic information analysis applications. Based on these domain decomposition solutions, GISolve also schedules distributed tasks and manages data transfers. In GISolve, these capabilities are designed as Grid services that are compliant with the open Grid service architecture (OGSA) and are implemented using Grid portal technologies. The GISolve implementation is illustrated based on a case study of a computationally intensive spatial statistic - [Gi(d)] that is used to assess spatial dependence among geographically distributional observations. © 2005 IEEE.

An emergency response activity usually involves several teams from different organizations working cooperatively for the purpose of saving lives or properties. These teams have to make many decisions under time pressure to accomplish their goals. Most decisions require contextual knowledge coming from the emergency settings, including those which report the activities of other emergency teams. The goal of this paper is to describe a system which aims at storing and disseminating the contextual knowledge required by teams during the course of an emergency.
