A Platform Independent Web-Based Data Managementn System For Random Access File

With the advent of the Web, the Internet has evolved into a user-friendly medium capable of high speed, on demand information delivery. Putting data onto the World Wide Web in the form of a fully accessible, searchable database can open up a wide variety of possibilities for teaching, learning and research. There are many different types of web-based database management system (DBMS), e.g., Oracle, Informix/Illustra, IBM DB2, Object Design, ranging from small systems that run on personal computers to huge systems that run on mainframes. However, these systems have limitations such as being platform dependent, not portable and expensive. This thesis describes the development of WebDB, a platform independent webbased data management system using Java servIets and random access files to address the problems. It is developed in order to provide the management functions to WebEd2000's database. WebEd2000 is a working prototype of Web-based distance learning system developed at the Broadband and ATM Research Group, Universiti Putra Malaysia (UPM). It enables delivering conventional lecture notes over the Web and providing various tools to help in managing and maintaining course materials in a server. The WebDB approach is for the ease of the centralized management of database administrator over the WebEd2000 users and maintains the database. It also enables instructors to access to their database and update it when necessary. Instead of WebEd2000 database, the system allows its users to put another database on the server. WebDB is mainly developed using the combination of Java servlets and JavaScript technologies. The server-side servlets are used to handle the requests from client and the responses from server. The random access file served as database repository in the database server where all the data is stored. The client-side JavaScript is used to enable DHTML features and perform less-security-concern processes in order to reduce the workload of the web-server. Lastly, WebEd can be easily set up and deployed in any platform and web-servers with minimal modifications. Portability is achieved by utilizing Java technology for the system applications and random access file as the data repository

Does Mobile Technology Matter? A Student Centric Perspective

Based on a student-centric perspective, this study seeks to understand how mobile technology influences students’ learning experiences. Our research motivation is driven by the increasing attention paid to mobile technology in the research and business community. Set in a public university setting, our investigation seeks to shed light on how teaching and learning could be reshaped by mobile technology, most specifically, emerging tablet PCs. The findings, based on two MIS (Management Information Systems) courses, one graduate and the other undergraduate, suggest that overall students perceived the mobility of tablet PC positively. In addition, graduate students expressed a higher degree of learning satisfaction and greater expectation of future technology usage than undergraduate students. Indeed, mobile technology seems to matter to students’ learning in general. The finding is particularly relevant when considering how to incorporate mobile technology into teaching practice as such technology-driven teaching practice is increasingly being expected in the contemporary networked society. Additional insights for managers, technology vendors, and college instructors are also discussed

Towards using online portfolios in computing courses

The direct experience we had with teaching a summer pre-college computing course in which we adopted an online portfolio approach has led us to consider the use of online portfolios in our regular computer science undergraduate courses. The technical challenges we foresee include: the necessary support from the college\u27s IT department; the use of Microsoft-based web authoring technologies vs. the use of Open Source / freeware counterparts; the need for adequate technical knowledge on the part of our faculty; the need for server-side hardware and software resources

New Method of Measuring TCP Performance of IP Network using Bio-computing

The measurement of performance of Internet Protocol IP network can be done by Transmission Control Protocol TCP because it guarantees send data from one end of the connection actually gets to the other end and in the same order it was send, otherwise an error is reported. There are several methods to measure the performance of TCP among these methods genetic algorithms, neural network, data mining etc, all these methods have weakness and can't reach to correct measure of TCP performance. This paper proposed a new method of measuring TCP performance for real time IP network using Biocomputing, especially molecular calculation because it provides wisdom results and it can exploit all facilities of phylogentic analysis. Applying the new method at real time on Biological Kurdish Messenger BIOKM model designed to measure the TCP performance in two types of protocols File Transfer Protocol FTP and Internet Relay Chat Daemon IRCD. This application gives very close result of TCP performance comparing with TCP performance which obtains from Little's law using same model (BIOKM), i.e. the different percentage of utilization (Busy or traffic industry) and the idle time which are obtained from a new method base on Bio-computing comparing with Little's law was (nearly) 0.13%.

E-learning and e-systems to facilitate learning from marked student work : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Computer Science at Massey University

Heinrich (2004a) first introduced the concept of 'electronic repositories of marked student work' and suggested an innovative approach of learning from marked student work. This research project further develops this e-learning approach. The learning approach was analyzed in the framework of modern educational theories, especially those relevant to formative assessment. Learning activities that mostly suit this new approach were identified. These activities show a large degree of variation in cognitive complexity and learning effectiveness, and according to their characteristics, can be associated with various learning styles. A range of factors that need to be considered in constructing learning processes based on these learning activities were investigated. The conceptualization of an e-learning environment to support the approach of learning from marked student work was developed. Three major objectives of developing such an e-learning environment were identified. Based on these objectives the general framework of e-learning from marked student work was outlined. There were very few applications of this approach in teaching practice and no study has been done on its effectiveness in the practical teaching before this research. An initial learning experiment using this approach was carried out. The effectiveness of this approach was evaluated and various aspects associated with this approach were investigated. To fully support this new learning approach, a web-based prototype system named E-Repositories of Marked Student Work, was developed. This research project developed opportunities for student learning and provided guidelines for teaching staff on how to reuse valuable learning resources in their teaching practice in the e-learning context
