Universal Measurement System with Web Interface (UMSWI) is presented in this paper. This is an autonomous, universal acquisition system which required development of flexible and easily extensible control. The choice of technologies, their flexibility, respect of limited resources and simplicity were the main consideration during design and development. Example implementation of oscilloscope and spectrum analyzer Web Graphic User Interface (WGUI) and Measurement Interface (ME) are described in details

The online campus map allows users to easily find buildings and rooms on campus. The program displays the location based on user input and location data stored in a database. The project originated from a software design class. Starting with the course's prototype system, our goal was to refine this project to improve its efficiency, maintainability, and interface.

2nd Conference on Internet Imaging

Since June 1998, EPFL's Visible Human Slice Server (http://***) allows to extract arbitrarily oriented and positioned slices. More than 300,000 slices are extracted each year. In order to give a 3D view of anatomic structures, a new service has been added for extracting slice animations along a user-defined trajectory. This service is useful both for research and teaching purposes (http://***/animation/). Extracting slices of animations at any desired position and orientation from the Visible Human volume (Visible Man or Woman) requires both high throughput and much processing power. The I/O disk bandwidth can be increased by accessing more than one disk at the same time, i.e. by striping data across several disks and by carrying out parallel asynchronous disk accesses. Since processing operations such as slice and animation extraction are compute-intensive, they require the program execution to be carried out in parallel on several computers. In the present contribution, we describe the new slice sequence animation service as well as the approach taken for parallelizing this service on a multi-PC multi-disk Web server.

The web affords unique opportunities to assist students in learning. Due to the rapid proliferation of the web in recent years, many educators seek to improve the effectiveness of their instruction by providing innovative web-based course material to their students. In particular, many web-based educational contents are being developed. It helps to teach and train students. It is spreading widely due to repeated learning any time, any where. In this paper we implemented C functions and quizzes for checking comprehension of statements in a C programming lecture, developing scenario related concepts and algorithm comprehension, We used visual representation. The web-based contents were implemented as FLASH animations or java applets.

A Visualization Tool for One- and Two-Way Analysis of Variance

JOURNAL OF STATISTICS EDUCATION 2005年第1期13卷

作者： Sturm-Beiss, Rachel CUNY Kingsborough Community Coll Dept Math & Comp Sci 2001 Oriental Blvd Brooklyn NY 11235 USA

Analysis of variance (ANOVA), a technique included in many introductory statistics courses, analyzes the relationship between a quantitative dependent variable and one or more independent qualitative variables. The nature of the relationship is expressed in a model with unknown parameters. Many textbooks emphasize the mechanics of the technique while the model and its parameters remain abstractions or theoretical entities. We introduce a java applet that allows a student to profitably explore the features and factors of one and two-way ANOVA tables together with representational models and model parameters.

The data observed by a FieldServer is output by one XML file per day. The list of image files taken by a FieldServer is output by one HTML file in which an array of image file names of javaScript for showing images as animation is written per day. Therefore, it was difficult to process data and images as long-term sequential data. We developed the preprocessor program for solving this problem, and developed the data and image viewer for a FieldServer using preprocessor's result. The preprocessor program uses SAX to analyze a lot of XML files. SAX has merits of less memory consumption and higher speed processing compared with using DOM. We developed two viewer programs, java applet version and java Servlet version. The former is easy to develop, but it takes several seconds to start up. The latter has a restriction in operability, but it can be executed without java plug-in on a Web browser.

In the nuclear fusion research community, tools for data analysis and visualization are very important for experts to do research work. WebScope is such a tool, which is to be used in the experiment of EAST(The Experimental Advanced Superconducting Tokamak) of Institute of Plasma Physics to display waveforms and will be more convenient for researchers to access and analyze data. It is an improvement to the former tool jScope and EastScope. WebScope is a tool with a B/S model on the Internet for data analysis and visualization on the EAST facility. so it can be used through web browser. With the goal of accessing, and analyzing the pivotal experimental data online, this data analysis and visualization system is implemented as java applet in the java programming language which can be included in an HTML page. In this way, researchers from all parts of the world can visit the tool WebScope through Internet, which is a dramatically convenient for them to analyze data at anywhere and anytime as long as there is Internet unnecessary to install it. what's more it can display data placed on different servers simultaneously. All of this is not supplied by jScope and EastScope. In conclusion, WebScope is a new and more promising tool for data analysis and visualization. This paper describes the process of its being brought forward, its advantages, its overview and its realization.

As the way of managing the distance learning process are commonly used LMS and LCMS, but it can also serve as a supplement of full-time study. In our case we teach with the support of e-courses, in which teachers insert different types of static as well as dynamic (interactive) materials. The importance of the interactivity in e-learning courses is often neglected. The interactivity allows learners to develop and shape their thinking, knowledge and skills. The paper deals with using of open-source simulator of electronic components and logic gates (logics) in LMS Moodle. It deals with the possibility of interactive communication between the java applet and the Moodle server. Students are able to send the realized task in the form of the screenshot of logic circuits directly from the applet to teachers.

Shows how visual programming can be used to teach the subject of binary tree algorithms. In our approach, the student implements a binary tree algorithm by manipulating abstract tree fragments (not necessarily just single nodes) in a visual way. This paper contributes to visual programming research by combining elements of animation, programming and proof to produce an educational visual programming tool. In addition, we describe our experiences with Opsis, a system we built to demonstrate the ideas in this paper (Opsis is a java applet and can be accessed at http://***/homes/amir/***). Finally, we make the claim that visual programming is an ideal way to teach data structure algorithms.

Conference on Computer Graphics, Imaging and Visualisation

As Internet and the World Wide Web (WWW) are becoming more and more popular, there is an increasing demand for new web services and developments. In particular, there is a need of new technologies (often referred to as Web3D) to create and manipulate interactive three-dimensional (3D) environments on the Web. A major problem in this subject is the lack of specialized 3D graphics libraries for Internet, with similar functionalities to those of OpenGL for standalone applications. Although several APIs (java3D, GJ4java, JOGL, LWJGL, jGL) have been proposed to tackle this issue, none of them has become an official part of core java package so far. Consequently, it is still hard to build reliable Internet-oriented 3D graphics programs providing the web users with the same realism and interactivity usually found on standalone applications. This paper proposes a based-on-java framework to develop interactive 3D graphics applications embedded in web pages. Our approach is not based on the development of new programming tools, the emphasis being placed upon the careful selection of already existing technologies (also described in this paper) that provide the best results for our goals along with the optimized design of the workflow. Some applications aimed at showing the potential of our approach are also briefly reported.
