The Design and Development of Exceptional Representation Based on Domain Ontology and Multi-agent Systems for E-Learning Purposes

Abstract—E-learning involves the use of digital content in the form of text and multimedia elements that are accessed via hyperlinks and also via browser or search engines. The search engines currently available to the learners are as offered by Acrobat Reader or Google which employ basic search-by-word-matching algorithms and present outputs in linear fashion based on occurrence in the text or arranged hierarchically by popularity or frequency of being accessed. This research aims to improve the meaningfulness of the search results which other systems focused on specifying the context of the search as offered by Yahoo, and the development of the semantic web as in wiki. These methods improve the search results but need further refinements to be truly effective in the e-learning environment. Thus, this study proposes the use of the exceptional representation of learning strategies based on domain ontology and multi-agent systems (MAS).

Intelligent Agent System Architecture for Presenting Health Grid Contents from Complex Database

Health grid contents determine a number of contents activities located in a number of different health institutions, whose contents information need to save in different storage units. To simplify the health contents representation in term of processing, segmentation and analyzing, we proposed intelligent agent system architecture to manage and retrieve healthcare contents in real world environment. This paper presents three structural processes which namely 1) Agent for retrieving and managing complex database contents, 2) Agent for processing queries within frequently processing cycle, and 3) Agent for approving contents to be presented.

Performance Analysis of TFRC and UDP over Mobile-IP Network with Computing Flows

In wireless networking, mobility is one of the key features. Mobility allows users to move around with their device within the given area that is covered by wireless network. This research aimed to conduct a performance analysis of TFRC and UDP over mobile-IP network with competing flows that enables to investigate three major performance metrics such as jitter, throughput, packet loss and packet delay. Two different transport layer protocols will be used in this analysis. Since mobility has been the core issue of computing of 21st century, hence, this research aims to contribute in this phenomena by measuring the performance analysis in mobile IP network, where mobile devices (nodes) are moved from access points to access points (AP) in order to exemplify the suitability of TFRC and UDP in wireless networking, moreover to collect data about crucial performance metrics features. The experiment was conducted by Network Simulation (NS-2).

A Sight on the Use of ICT Resources for E-Learning in the Iraqi Higher Education Institutions (IHEI): A Framework for the Use of ICT in E-learning

The current need for adapting the key elements contribute to the globalization and the revolution in information and communication technologies is one of many challenges facing Iraq today. In such condition, the Iraqi teaching and learning society in different institutions should be transformed into a competitive actor, which consider as serious implications for educational institutions with regard to their nature and purpose. Therefore, the Ministry of Education in Iraq (MoE) seeks the possible ways to focus on the building sustainable capacity to use e-learning for the continuous improvement of curricula, instruction, learning and assessment, focusing on ICT as a trans-formative and integrating force. This paper aims at reviewing the current literature relates to the use of ICT resources in education in different developing countries.

Interpreter service development for new learners of the network simulation-2 (NS2) based on J2EE

Recently, different combination of integrating technology provides software developers with the suitable methods and procedures for designing, executing, arranging, and expanding comprehensive distributed systems. The main issues raised among the software programmers are the lacking to provide them with the suitable interpreter services to guide and assist them during learning, an example of these software is NS2. Thus, this paper intended to enhance the current implication of NS2 to be able to indicate and correct the coding errors during programming.

Indexed Sequential Access Method (ISAM): A Review of the Processing Files

Indexed sequential access method (ISAM) is used widely for processing database operations among different platforms with definite characteristics. The classification of these indexes in the data set processing determines various managing of the records. They can be shown by several indexes of an employee in the one database that sequentially joined based on the provided set of information. Several issues in managing the data set were addressed in terms of storing, processing, and retrieving of data records into the column, this due to the lacking in understanding the ISAM sequential procedure for managing data. Thus, this paper intends to demonstrate the classification of ISAM within the platforms and the working procedure as well as the indexing schema for this method in processing files.

Managing ICT Resources in E-learning Environment: Challenges, Issues and a Proposed Model

Of late, we have seen a tremendous change in our education system due to the rapid advancement of ICT and the Internet. Not only the teaching and learning process have been influenced by this technology, the way the education system is managed has also been affected. However, there is a need to study how ICT resources are managed in such electronic learning environment. In this article, the literature review on previous studies pertaining to ICT resources as well as the challenges and issues in managing such resources will be discussed. In addition, a learning management model for ICT resources is also suggested.

The effectiveness of an inquiry-based computer-simulated lesson in physics

Robust as they are, the existing instructional design prescriptions (Reigeluth, 1983; 1999) which are content-based, expository- and individual-oriented, and generally technology-free are of little use when the task is to design inquiry-based computer-simulated lessons for teaching scientific thinking skills in cooperative learning environments. Thus, the aims of this study were to design a computer-based simulation lesson employing currently available PC and internet software and investigate its effectiveness in various learning situations. The heart of the lesson was the utilitarian Gas Law Simulation program developed by Abraham, Gelder, and Haines (2002) that was incorporated into a hypertext interface display with active links to related notes and worksheets and a superimposed Microsoft Excel table and chart-plotting facility. This package allowed students to review the concepts involved and see relationships between the variables in graphical forms when a selected independent variable was manipulated and all the corresponding values were keyed into the Excel table. A science process skill and HD thinking worksheet was drawn following Lawson’s (1995) prescriptions and the questions and activities were further modified to fit the local syllabus and physics texts. A pilot study was conducted to evaluate and refine the lesson and field testing was conducted using a 3 x 2 factorial design. The first factor was the inquiry-based computer simulation lesson with three modes of cooperative learning, namely, heterogeneous-ability cooperative learning (HACL) group, friendship-based cooperative learning (FCL) group, and traditional group work (TGW) group. The HACL and FCL group were trained following the Kagan (1994) Cooperative Learning Structure while the TGW group which was essentially another friendship-based learning group was not instructed on the Kagan (1994) Cooperative Learning Structure. The second factor was student reasoning ability, namely, empirical-inductive (EI) and hypothetical-deductive (HD) abilities. The sample consisted of 301 Form Four (16-year-old) science students. The results showed that students in the HACL group significantly outperformed their counterparts in the FCL group who, in turn, significantly outperformed their counterparts in the TGW group in scientific thinking and conceptual understanding. The study found that the inquiry-based computer simulation program was effective in enhancing scientific reasoning and conceptual understanding of students of all reasoning abilities but for maximum effectiveness cooperative learning groups should be composed of students of heterogeneous abilities.
