Software Internationalization: A Framework Validated Against Industry Requirements For Computer Science And Software Engineering Programs, John Huân Vũ

Master's Theses

View John Huân Vũ's thesis presentation at http://youtu.be/y3bzNmkTr-c.

In 2001, the ACM and IEEE Computing Curriculum stated that it was necessary to address "the need to develop implementation models that are international in scope and could be practiced in universities around the world." With increasing connectivity through the internet, the move towards a global economy and growing use of technology places software internationalization as a more important concern for developers. However, there has been a "clear shortage in terms of numbers of trained persons applying for entry-level positions" in this area. Eric Brechner, Director of Microsoft Development Training, suggested …

Web site usage statistics are a widely used tool for Web site development, but libraries are still learning how to use them successfully. This case study summarizes how Morris Library at Southern Illinois University Carbondale implemented Google Analytics on its Web site and used the reports to inform a site redesign. As the main campus library at a research university with about 20,000 undergraduate and graduate students, the library included resources from multiple library departments on a single site. In planning the redesign, Morris Library's Virtual Library Group combined usage reports with information from other sources, such as usability tests …

An Open Source Graphics Engine For Three-Dimensional Video Games, David Lee Gardner Stover

Theses Digitization Project

The focus of this project is creating a new three dimensional (3D) game called Mythic which was developed at CSUSB. To support Mythic, a new game engine called Geng which is derived from "game" and "engine" is also being developed in the School of Computer Science and Engineering at CSUSB. MAGE, called the Multi-platform All purpose Graphics Engine provides support for keyframe animation, Cg, vertex and fragment shaders GLSL vertex and fragment shaders, loading static models stored in the Collada file format. The architecture of MAGE is based on a unified 3D graphics API that hides the specific implementation details …

The College Of Extended Learning Online Registration System, Ching-Yi Wang

Theses Digitization Project

The purpose of this study was to build an online method to register for classes for the College of Extended Learning Online Registration System (CELORS). This system was initially built so that the College of Extended Learning could offer its students an online method to register for classes, in addition to the traditional methods of registering by phone, by fax, by mail, or in person. Over the last few years, the system has been routinely modified to meet the needs of the College to suit their ever-changing business rules.

Smart Objects In A Virtual World, Akihiro Eguchi

Inquiry: The University of Arkansas Undergraduate Research Journal

The coming Internet of Things will usher in a smart semantic world where many more physical objects will be networked so that they can communicate with each other and with humans. This paper identifies protocols that smart objects will need to follow and the ways in which today’s virtual worlds can be used to better design and understand these protocols for tomorrow’s smart world.

Xpu: A Distributed Architecture For Metaverses, Francis Chang, C. Mic Bowman, Wu-Chi Feng

Computer Science Faculty Publications and Presentations

A significant problem of designing 3D virtual worlds (such as metaverses) is developing a scalable architecture that can manage millions of simultaneous users in an interactive 3D environment. This paper presents XPU (Extremely Partitioned Universe), a hierarchical client-server architecture for developing highly scalable metaverses. This design addresses the problem of dynamically partitioning the world to manage network and computing resources.

Supporting Multiple Paths To Objects In Information Hierarchies: Faceted Classification, Faceted Search, And Symbolic Links, Saverio Perugini

Computer Science Faculty Publications

We present three fundamental, interrelated approaches to support multiple access paths to each terminal object in information hierarchies: faceted classification, faceted search, and web directories with embedded symbolic links. This survey aims to demonstrate how each approach supports users who seek information from multiple perspectives. We achieve this by exploring each approach, the relationships between these approaches, including tradeoffs, and how they can be used in concert, while focusing on a core set of hypermedia elements common to all. This approach provides a foundation from which to study, understand, and synthesize applications which employ these techniques. This survey does not …

Beyond The Pie: Communicating With Smart Objects Using Menu-Based Natural Language Interfaces, Tanmaya Kumar

Inquiry: The University of Arkansas Undergraduate Research Journal

In both real and 3D virtual worlds, people and avatars (representations of people) need to be able to communicate with things around them. Without guidance, however, people cannot use the language that the things can understand. The goal of our research is to extend the 3D virtual world Second Life® to better model pervasive computing and overcome the boundaries of communication. The aim of this paper is to show how to build a dynamic menu-based user interface that enables humans to communicate with model entities. The focus is the applicability of object-specific grammars associated with things (objects in the real …

Motion In Augmented Reality Games: An Engine For Creating Plausible Physical Interactions In Augmented Reality Games, Brian Mac Namee, David Beaney, Qingqing Dong

Articles

The next generation of Augmented Reality (AR) games will require real and virtual objects to coexist in motion in immersive game environments. This will require the illusion that real and virtual objects interact physically together in a plausible way. The Motion in Augmented Reality Games (MARG) engine described in this paper has been developed to allow these kinds of game environments. The paper describes the design and implementation of the MARG engine and presents two proof-of-concept AR games that have been developed using it. Evaluations of these games have been performed and are presented to show that the MARG engine …

Cbtv: Visualising Case Bases For Similarity Measure Design And Selection, Brian Mac Namee, Sarah Jane Delany

Conference papers

In CBR the design and selection of similarity measures is paramount. Selection can benefit from the use of exploratory visualisation- based techniques in parallel with techniques such as cross-validation ac- curacy comparison. In this paper we present the Case Base Topology Viewer (CBTV) which allows the application of different similarity mea- sures to a case base to be visualised so that system designers can explore the case base and the associated decision boundary space. We show, using a range of datasets and similarity measure types, how the idiosyncrasies of particular similarity measures can be illustrated and compared in CBTV allowing …

Inside The Selection Box: Visualising Active Learning Selection Strategies, Brian Mac Namee, Rong Hu, Sarah Jane Delany

Conference papers

Visualisations can be used to provide developers with insights into the inner workings of interactive machine learning techniques. In active learning, an inherently interactive machine learning technique, the design of selection strategies is the key research question and this paper demonstrates how spring model based visualisations can be used to provide insight into the precise operation of various selection strategies. Using sample datasets, this paper provides detailed examples of the differences between a range of selection strategies.

Website Accessibility Issues In Western Australian Public Libraries, Vivienne L. Conway

Eliciting User Requirements Using Appreciative Inquiry, Carol Kernitzki Gonzales

CGU Theses & Dissertations

Many software development projects fail because they do not meet the needs of users, are over-budget, and abandoned. To address this problem, the user requirements elicitation process was modified based on principles of Appreciative Inquiry. Appreciative Inquiry, commonly used in organizational development, aims to build organizations, processes, or systems based on success stories using a hopeful vision for an ideal future. Spanning five studies, Appreciative Inquiry was evaluated for its effectiveness with eliciting user requirements. In the first two cases, it was compared with traditional approaches with end-users and proxy-users. The third study was a quasi-experiment comparing the use of …

Representations Of Keypoint-Based Semantic Concept Detection: A Comprehensive Study, Yu-Gang Jiang, Jun Yang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Based on the local keypoints extracted as salient image patches, an image can be described as a "bag-of-visual-words (BoW)" and this representation has appeared promising for object and scene classification. The performance of BoW features in semantic concept detection for large-scale multimedia databases is subject to various representation choices. In this paper, we conduct a comprehensive study on the representation choices of BoW, including vocabulary size, weighting scheme, stop word removal, feature selection, spatial information, and visual bi-gram. We offer practical insights in how to optimize the performance of BoW by choosing appropriate representation choices. For the weighting scheme, we …
