Psychological Sense of Community in On-Line Learning Environments
… Current literature discusses differences among populations as they relate to face-to-face learning communities. However, no literature exists to determine if these same differences exist in an on-line learning environment. Since community has been closely linked to social and academic …

Collaboration in Developing On-Line Learning Between Two Different Countries: a Case Study
Collaboration between institutions in distance learning has been practiced for decades at first domestically and now expanding to an international level. Many higher education institutions are also trying to globalize their learning environments through the internationalization process, especially …

Nonlinear Controller Design and Implementation for a Magnetic Levitation System
<p>In this study, an approach is presented to nonlinear control of a magnetic levitation system using artificial neural networks (ANNs). Two neural networks, the multi-layer perceptron (MLP) and the single multiplicative neuron (SMN), are investigated in this work. A novel form of ANN, namely, …

The design, implementation and evaluation of a web-based learning environment for distance education
… at a distance using a multi-level evaluation framework. A Web-based learning environment was designed, developed, implemented and evaluated for this purpose. Constructivist epistemology provided the basis for developing various components and developing problem-centred and interactive …

Statistical Recursive Estimation Algorithms for Speaker Adaption
… the development of statistical recursive estimation algorithms for speaker adaptation. In this thesis, a unified framework for recursive maximum likelihood estimation and recursive Bayesian learning is first developed and applied to direct hidden Markov model parameter estimation. Then an online …

Transformation of data into knowledge within higher education
<p>Establishing institutional effectiveness has beleaguered U.S. higher education institutions for thirty years. One key element of institutional effectiveness is the ability of an organization to use data for effective decision-making. This study provides new insight into this critical component …

Gauss-newton Based Learning For Fully Recurrent Neural Networks
The thesis discusses a novel off-line and on-line learning approach for Fully Recurrent Neural Networks (FRNNs). The most popular algorithm for training FRNNs, the Real Time Recurrent Learning (RTRL) algorithm, employs the gradient descent technique for finding the optimum weight vectors in the …

A gradient optimization approach to adaptive multi-robot control
This thesis proposes a unified approach for controlling a group of robots to reach a goal configuration in a decentralized fashion. As a motivating example, robots are controlled to spread out over an environment to provide sensor coverage. This example gives rise to a cost function that is shown …

Adaptive intelligent personalised learning (AIPL) environment
As individuals the ideal learning scenario would be a learning environment tailored just for how we like to learn, personalised to our requirements. This has previously been almost inconceivable given the complexities of learning, the constraints within the environments in which we teach, and the …

Community College Students Taking Online Courses: The Student Point-of-View
This study is a qualitative examination of community college students' experiences taking on-line courses. The study addresses the research question, "How do community college students construct their on-line experiences?" In order to answer this question, the following foci were examined: What are …

The role of context in instructional design: A case study examining the re-purposing of web-based master's degree courses for use in Malawi
This case study examined how contextual factors influenced the adaptation of on-line courses created in the United States as they were re-purposed for use in Malawi. The investigation starts and ends within Year Two of a five year project funded by the United States Agency for International …

Efficient reinforcement learning via singular value decomposition, end-to-end model-based methods and reward shaping
Reinforcement learning (RL) provides a general framework for data-driven decision making. However, the very same generality that makes this approach applicable to a wide range of problems is also responsible for its well-known inefficiencies. In this thesis, we consider different properties which …

Voice Interactive Classroom, a service-oriented software architecture to enable cross-platform multi-channel access to Internet-based learning
Software technology is creating a ubiquitous context for human living and learning in which new modes of interaction are gradually being incorporated. At the same time, interaction with Internet-based learning systems has evolved from using the traditional access from a personal computer or …

Perceptions on the Diffusion and Adoption of SkillSoft®, an e-learning program: A Case Study of a Military Organization
… study was to better understand how the diffusion (spread) and adoption (acceptance) of SkillSoft® (an e-learning product) occurred among employees of one military organization and to distill individual perceptions regarding influences that affected the process. This case study focused on the …

QoS-based experience-aware adaptation in multimedia e-learning - A learner, is a learner, is a user, is a customer
One of the challenges for the future of technology-enhanced learning is the retention of learners. On-line learning environments should engage learners and provide an appropriate “Quality of Experience” (QoE). For more than a decade, adaptive hypermedia systems have been used to adapt content and …

Coordinated UAV Target Assignment Using Distributed Calculation of Target-Task Tours
… the improvement of cooperative task allocation to vehicles in multiple-vehicle, multiple-target scenarios through the use of more effective preplanned tours. Effective allocation of vehicles to targets requires knowledge of both the team objectives and the contributions that individual …

Reinforcement Learning and Reward Estimation for Dialogue Policy Optimisation
Modelling dialogue management as a reinforcement learning task enables a system to learn to act optimally by maximising a reward function. This reward function is designed to induce the system behaviour required for goal-oriented applications, which usually means fulfilling the user’s goal as …

A framework for an adaptable and personalised e-learning system based on free web resources
An adaptable and personalised E-learning system (APELS) architecture is developed to provide a framework for the development of comprehensive learning environments for learners who cannot follow a conventional programme of study. The system extracts information from freely available resources on …

Universal semantic communication
Is meaningful communication possible between two intelligent parties who share no common language or background? We propose that this problem can be rigorously addressed by explicitly focusing on the goals of the communication. We propose a theoretical framework in which we can address when and to …
