Knowledge Discovery In Biological Databases : A Neural Network Approach, Qicheng Ma

Dissertations

Knowledge discovery, in databases, also known as data mining, is aimed to find significant information from a set of data. The knowledge to be mined from the dataset may refer to patterns, association rules, classification and clustering rules, and so forth. In this dissertation, we present a neural network approach to finding knowledge in biological databases. Specifically, we propose new methods to process biological sequences in two case studies: the classification of protein sequences and the prediction of E. Coli promoters in DNA sequences. Our proposed methods, based oil neural network architectures combine techniques ranging from Bayesian inference, coding theory, …

The Importance Of Communication Skills: Perceptions Of Is Professionals, Is Managers, And Users, Ruth A. Spurlock Miller

Doctoral Dissertations

Information systems (IS) research has shown that communication skills tend to be more important than technical skills to IS staff in project development activities. Yet, research findings indicate that IS staff are lacking in the communication skills they need to interact successfully with users and managers during systems development. Thus, the two purposes of this research were (1) to determine whether IS staff, IS managers, and IS users differ in their perceptions of important communication skills that IS staff need and (2) if differences do exist, to assess the impact of the differences on user satisfaction with IS product and …

Genetically Evolved Dynamic Control For Quadruped Walking, Giorgio Grasso

Dissertations

The aim of this dissertation is to show that dynamic control of quadruped locomotion is achievable through the use of genetically evolved central pattern generators. This strategy is tested both in simulation and on a walking robot. The design of the walker has been chosen to be statically unstable, so that during motion less than three supporting feet may be in contact with the ground.

The control strategy adopted is capable of propelling the artificial walker at a forward locomotion speed of ~1.5 Km/h on rugged terrain and provides for stability of motion. The learning of walking, based on simulated …

Component-Based Software Engineering, Zhiyuan Wang

Dissertations

To solve the problems coming with the current software development methodologies, component-based software engineering has caught many researchers' attention recently. In component-based software engineering, a software system is considered as a set of software components assembled together instead of as a set of functions from the traditional perspective. Software components can be bought from third party vendors as off-the-shelf components and be assembled together.

Component-based software engineering, though very promising, needs to solve several core issues before it becomes a mature software development strategy. The goal of this dissertation is to establish an infrastructure for component-based software development. The author …

Applications Of Agent Architectures To Decision Support In Distributed Simulation And Training Systems, Plamen V. Petrov

Dissertations

This work develops the approach and presents the results of a new model for applying intelligent agents to complex distributed interactive simulation for command and control. In the framework of tactical command, control communications, computers and intelligence (C₄I), software agents provide a novel approach for efficient decision support and distributed interactive mission training. An agent-based architecture for decision support is designed, implemented and is applied in a distributed interactive simulation to significantly enhance the command and control training during simulated exercises. The architecture is based on monitoring, evaluation, and advice agents, which cooperate to provide alternatives to the …

Development And Characterization Of Techniques For Neuro-Imaging Registration, Carlo Ciulla

Theses

Three automated techniques were developed for the alignment of Neuro-Images acquired during distinct scanning periods and their performance were characterized. The techniques are based on the assumption that the human brain is a rigid body and will assume different positions during different scanning periods. One technique uses three fiducial markers, while the other two uses eigenvectors of the inertia matrix of the Neuro-Image, to compute the three angles (pitch, yaw and roll) needed to register the test Neuro-Image to the reference Neuro-Image. A rigid body transformation is computed and applied to the test Neuro-Image such that it results aligned to …

Collaborative Software Agents Support For The Texpros Document Management System, Jrtian Lin

Dissertations

This dissertation investigates the use of active rules that are embedded in markup documents. Active rules are used in a markup representation by integrating Collaborative Software Agents with TEXPROS (abbreviation for TEXt PROcessing System) [Liu and Ng 1996] to create a powerful distributed document management system. Such markup documents with embedded active rules are called Active Documents. For fast retrieval purposes, when we need to generate a customized Internet folder organization, we first define the Folder Organization Query Language (FO-QL) to solve data categorization problems. FO-QL defines the folder organization query process that automatically retrieves links of documents deposited into …

Key Decision-Making Phases And Tasks For Outsourcing Information Technology, Ashraf Shoeib

Theses: Doctorates and Masters

Outsourcing has become an attractive option for today's organisation. Since outsourcing Information Technology (IT) is a relatively new phenomenon in Australia, little research has been conducted as to IT management strategies needed when considering outsourcing. To guide management in the decision whether or not to outsource IT, the study developed and tested a decision-making model comprising the phases of intelligence, analysis and planning, strategy selection, action, and evaluation and monitoring. The significance of decision phases and tasks contained in the model was established through a survey of major Australian organisations. The sample included Australia's top 390 companies. Such organisations would …

The Next Generation: A Look At Where Today's Enterprise Resource Planning (Erp) Systems Came From And Where Technology Is Heading, Lance Ronald Lenhert

Theses Digitization Project

"Currently, the largest barrier to any given market usually involves capital. If a company does not have enough investment capital to start with, it could fail before it even gets started. However, there is a new component that affects some of the largest corporations in the world. The problem relates to being able to sustain current internal processing, as well as adapt and grow in new markets with higher volumes. There are systems out there today that claim to address these issues along with e-commerce and other electronic sharing of information."
