Title: Reusability and adaptability of interactive resources in web-based educational Description: The production of interactive multimedia content is in most cases an expensive task in terms of time and cost. Hence, optimizing production by exploiting the reusability of interactive multimedia elements is mandatory. Reusability can be triggered by a combination of resuable multimedia components and the appropriate use of metadata to control the components as well as their combination. In this article, we discuss the reusability aspects of interactive multimedia content in web-based learning systems. In contrast to existing approaches, we extend a component-based architecture to build interactive multimedia visualization units with the use of metadata for reusability and customizability. In the three-tier model, the lowest layer of the paradigm corresponds to the programmer (code reusability). The user interface of an educational visualization is located at the top layer where the interaction with the end-user (student) takes place. The educator is located between the top and the bottom layers. This medium layer allows adapting interactive multimedia content according to the needs of the user, applying a predefined set of metadata. The teacher can both adjust the level of explanation and the level of interactivity of an animation, and influence the presentation and the results of the algorithms being illustrated (program reusability). After a theoretical overview, we explain our architecture by giving an example of an application. Keywords: Design;Theory

Title: Simulation of the 1-Dimensional Discrete Cosine and Fourier Transforms Description: This applet belongs to the context of Multimedia or Signal Procesing. It simulates the one dimensional discrete cosine transform and the one dimensional discrete Fourier transform. Both transforms are a basis for modern signal processing algorithms like the JPEG image compression standard. When confronted with the mathematical formulas, most students show difficulties in understanding the notion of "time domain" and "frequency domain", or of "superposition of different frequencies". The applet simulates the transformation of a 1 dimensional signal. The amplitudes of the different frequency components can be modified, and the effect on the signal will get clearer. The user interface of the applet has been built to stimulate the user to play around with the tool. The applet is highly interactive and very flexible. One can choose between a number of given input signals or the user can build a signal by himself. Of course, a solution for every input is provided.

Title: Simulation of the 2-dimensional DCT Description: This applet visualizes the 2 dimensional DCT as it is used in the JPEG compression standard. Also, most of the Internet compressions standards for video (Motion JPEG, H.261, H.263) are based on the Discrete Cosine Transform (DCT) which splits an image up into blocks of 8x8 pixels. Our applet tries to clear out the problems with the 2 dimensional DCT by invoking the "play instinct" of students: The user can chose discrete 8x8 (2-D) input values in the range 0 to 255 for the grey value of the pixels. In the frequency domain, rulers allow to adjust the amplitudes of the different frequencies. A backward transform plots the resulting grey values from the chosen ampitudes over the initial input values. The task is to find the "correct" amplitudes in the frequency domain to recover the initial signal. Of course, we have included a solution to the problem...

Title: A New and More Efficient Implementation of an Undirected Graph Component Description: This research project entails designing, specifying, coding, testing, debugging, and documenting different implementations of an undirected graph component for the RESOLVE/C++ Component Catalog. Each version uses the same abstract model to represent the state of an undirected graph and the same kernel operations to manipulate the state of that undirected graph. The implementation strategy changes for each version. The first five versions utilize the "classic" strategies (adjacency list, adjacency matrix, and edge list) in a variety of ways. The final version employs a novel data structure that allows each operation to execute in constant time, which dominates the other strategies.

Title: Ast and secure distributed read-only file system Description: The self-certifying read-only file system enables secure distribution of public, read-only content. It is similar to anonymous FTP or the Web, except that it serves integrity-protected content. That is, an adversary cannot trick a user into accepting unauthentic content. The read-only file system pushes the cost of cryptography entirely onto clients, allowing servers to scale to many clients. To publish content, an administrator creates off-line a signed database of a local file system. Untrusted replicas then serve the content to clients. We demonstrate how to use the read-only file system to implement certificate authorities and securely distribute software. Keywords: security;file systems;cryptography;;hash trees

Title: The Old World Meets the New: Utilizing Java Technology to Re-vitalize and Enhance NASA Scientific Legacy Code Description: A general purpose client/server architecture has been developed to effect the modernization of legacy code. This technique utilizes platform independent graphical user interfaces and interactive visualizations. The client/server configuration exploits a content-taggable data stream which allows seamless integration with the legacy application. This allows the client to orchestrate the collection of data in a more graphically interactive manner than was present in the original legacy interface. Application of this architecture to a NASA Global Scientific Model was demonstrated. The enhanced model incorporating this architecture will support data interpretation for NASAs TIMED satellite mission, including distributed investigations managed via a remote server.

Title: A framework to support teaching in distributed systems Description: Computer networks and distribute systems are characterized by highly dynamic, concurrent, and complex processes. Thus, training in this area requires great effort from both teachers and learners. Teachers are disatisfied with available methods for presentation, explanation, and exercises, and they are looking for better methods to support learners. We have developed and architecture called Highly interactive simulation of algorithms and Protocols (HiSAP), consisting of a framework to build simulations and generate applets from formally specified algorithms or protocols. By modifying this specification and observing the resulting behavior, teaching and learning in a constructive manner is enabled. The framework is open to plug-in tools to show various aspects of HiSAP's behavior. We present the results of some experiments with HiSAP at three different lectures for graduate students of distributed systems and computer networks. Keywords: interactive learning;tool kit

Title: Empirical Study of Course Scheduling Methods Description: Authors: Prakash Ojha Abigail Walker Jennifer Wanner Hope College Xavier University Computer Science Mathematics and Computer Science Holland MI 49423 Cincinnati OH 45207-4441 ojha@cs.hope.edu awalker@cerebro.xu.edu wanner@cerebro.xu.edu Research advisor: Gary Lewandowski, Xavier University, lewandow@cerebro.xu.edu Poster Title: Empirical Study of Course Scheduling Methods Category: Undergraduate Extended Abstract: Problem and Motivation Course scheduling involves building a timetable for courses such that the students who want to take courses can successfully take every course they would like. There are many variations to this problem, including inclusion of faculty constraints, room constraints, and multiple sections. The problem is known to be NP-Complete, thus many researchers have worked on approximation solutions to the problem. Researchers have generally focused on one solution method, one unique version of the problem definition, and one set of data based on local needs. This localization of the problem has resulted in many studies but no general consensus of the best method available. In this study, we explore several methods from the literature on a single definition of the problem, and on a common set of data. Our goals are two-fold. First, we provide a problem statement, data, and a random data generator to facilitate easy benchmarking of methods and techniques. Second, we explore the best method for those who may be non-experts and need to schedule courses. Background and Related Work While a great deal of research has been done on scheduling methods, our study concentrates on two of the most promising efforts: iterative improvement and linear programming. Iterative improvement methods for scheduling including faculty constraints have been studied in particular by Glover [3], and Chahal and DeWerra [1]. Hertz's use of Tabu search considers many different constraints [4]; we have adopted many of these constraints in our benchmark formulation of the problem. Our modification to the problem and our new data provides a different testbed for this algorithm and allows it to be compared against other methods. Linear programming allows one to formulate an equation for the optimal solution to the problem; practical solutions involving this method are infrequent [2], and do not consider many of the constraints we consider. Approach and Uniqueness We address the problem of comparing results from the literature in two ways. First, we define one statement of the course scheduling problem, involving faculty, students, and multiple sections, and adapt several of the approaches from the literature to this problem. Thus, any comparison of the approaches will start from the same problem definition. Second, we provide a random data generator that generates student course requests in such a way that an optimal solution must exist. Finally, we have studied five methods for course scheduling in our study: A greedy algorithm that simply schedules courses to the first available time (results from this simple method give some idea as to the usefulness of more complex methods), iterative improvement algorithms following a hill-climbing philosophy and following a "random improvement" philosophy in which a solution with a poorer evaluation may be used to continue the search for an improved solution, linear programming, and an algorithm that creates a bipartite matching problem for scheduling each student based on the times available for each course requested. Our formulation of the course scheduling problem used is as follows: We are given information about the courses (number of sections, faculty members teaching the course, times at which the course can be taught), lists of desired student courses, and the number of timeslots in which to schedule the courses. Courses are grouped into departments and for each department we have information on how many courses from that department may be scheduled concurrently (representing room availability constraints). The goal of the problem is to build a timetable and schedule for students' courses minimizing student conflicts while satisfying constraints on faculty and room availability. This study provides a repeatable and expandable comparison of scheduling methods. The algorithms were tested on random data and on data from a DIMACS benchmark for graph coloring that involves course scheduling. The generator and benchmark data are publically available, thus other methods can be tested on the same or very similar data. Results and Contributions We have developed a data generator that generates student course requests given the description of a timetable (the number of courses in the table, and the number of sections of each course), the section bound for each course, and the number of schedules desired. The generator builds a random timetable, and then generates student course requests using a backtracking technique that ensures the student can get each course requested. Information on which section the student would attend and the time of each course is stripped from the data so the data appears real to the algorithms. We conducted a study of the methods described above on thirteen sets of randomly generated data. Each method was run five times and we used the median to compare how close each method comes to scheduling courses optimally. (The Linear Programming method could not be tested because our formulation resulted in so many variables that our machines ran out of memory.) We have drawn the following conclusions from our empirical study. First, the greedy algorithm is not competitive with other approximation methods, meaning the time spent developing and using these methods is worthwhile. Second, iterative improvement is currently the best practical method for course scheduling when the courses have only a single section each. Third, when courses have multiple sections each, bipartite matching is very competitive with the iterative improvement algorithms while running much faster. References [1] N. Chahal and D. deWerra.

Title: Course and exercise sequencing using metadata in adaptive hypermedia learning Description: <p>In the last few years the (semi-) automatic sequencing of course material has become an important research issue, particularly the standardization of metadata for educational resources. Sequencing can help to generate hypermedia documents which, at their best match the learner's needs. To perform (semi-) automatic course sequencing, a knowledge library as well as modular resources can be used. Both must be described by metadata.</p> <p>First, metadata standards (IEEE Learning Objects Metadata, Instructional Mangement Systems Global Learning Consortium, Dublin Core) are analyzed with regard to course sequencing. As an application example, Multibook, an adaptive hypermedia system used to teach multimedia technology, is described. Multibook uses metadata to create course sequences semi-automatically. In this article we explain how a knowledge library can be used to create exercises automatically. We give an example of how courses can be sequenced in general by analyzing the creation of exercises. An evaluation of our system shows the advantages and drawbacks of the automatic sequencing approach.</p> Keywords: Documentation;Management

Title: Using a theoretical multimedia taxonomy framework Description: <P>Multimedia (MM) is a polysemous term, a term with many definitions, and in this case, many roots. In this paper, multimedia is defined as the seamless integration of two or more media. Each ancestor brings another requirement, muddying the field and making it difficult to work through. A multimedia taxonomy based on a previous media taxonomy is proposed to help organize the discipline. The taxonomy helps to classify the space called multimedia and to draw attention to difficult issues. The paper outlines the forms contributing to multimedia--text, sound, graphics, and motion--and aligns them with probable formats--elaboration, representation, and abstraction-- and sets them within a context--audience, discipline, interactivity, quality, usefulness, and aesthetics. The contexts are more clearly defined in two areas: interactivity and the information basis for a discipline. Examples are presented describing the use of the taxonomy in the design and evaluation of student projects in a computer science-based multimedia course.<p> Keywords: computer uses in education;evaluation;multimedia;design;theory

It is often necessary to share these resources in real time, for instance when an instructor teaches remote students how to use a certain resource explains the theory behind it. We have developed some tools for this purpose that emulate a virtual classroom, and are primarily designed for synchronous sharing of resources. They enable participants to share Java objects in real time and also allow the instructor to dynamically manage the telebearing session.</P> Keywords: Design

Title: Simulation of Embedded Kernels over Pthreads Description: This work describes the design and implementation of a simulation environment for an open-source embedded kernel and an intuitive user interface to complement it. The study stresses the suitability of POSIX Threads (Pthreads) to resemble kernel operations in the simulation environment. It specifies the prerequisites for using Pthreads as a means to resemble embedded task execution and suggests an I/O-based representation of device information. The experience gained with a sample implementation stresses the importance of a proper match between a Pthreads implementation and an embedded kernel. It also shows the adequacy of both the simulation environment and a graphical user interface to aid program development and debugging. Furthermore, the separation of the simulation component from the user interface provides opportunities to utilize each component separately or even combine them with other components. The simulation environment is publically available with further instructions included in the appendix. Keywords: Embedded Systems;Operating Systems Kernel Simulator

Title: GLOMAR: Adaptive Consistency Control for Distributed File Systems Description: With the increased heterogeneity of networked devices integrating into existing distributed file system (DFS) topologies, the ability to balance hardware constraints with user and software requirements is paramount. This is especially true for consistency control in file systems. Existing DFSs usually implement a single general-purpose consistency control approach, focusing on a specific scenario, rather than the multitude of possibilities that can arise due to heterogeneity and variability of current computing environments. The developed GLOMAR system caters for the multitude of possibilities, by providing the framework and abstraction that allows numerous consistency control mechanisms specifically built for a scenario to be implemented under the one DFS. This extended abstract discusses the motivation and design of GLOMAR, detailing its Microsoft .NET implementation. Keywords: distributed file system;consistency control;concurrency;middleware

Title: V-VIS: New Methods of Passive Information Grouping in a Classroom Tool for Low Vision Students Description: Mobile computing devices now make it possible to develop low-cost, portable assistive technology. The current lack of satisfactory technology to aid visually impaired students drives our development of a handheld-based viewer for Visually Impaired Students (v-VIS) designed to assist in note taking. v-VIS is a real-time viewer and recording system for professor's notes written on an electronic blackboard. The interface integrates magnification and high-contrast color schemes, enabling students to view the transcribed information in real-time. However, the large e-blackboard transmitting visual information to a small-screened handheld creates a screen-mapping problem for which two solutions have been designed and compared objectively.
