A Novel Approach To Data Deduplication Over The Engineering-Oriented Cloud Systems, Zhe Sun, Jun Shen, Jianming Young

Faculty of Informatics - Papers (Archive)

This paper presents a duplication-less storage system over the engineering-oriented cloud computing platforms. Our deduplication storage system, which manages data and duplication over the cloud system, consists of two major components, a front-end deduplication application and a mass storage system as back-end. Hadoop distributed file system (HDFS) is a common distribution file system on the cloud, which is used with Hadoop database (HBase). We use HDFS to build up a mass storage system and employ HBase to build up a fast indexing system. With a deduplication application, a scalable and parallel deduplicated cloud storage system can be effectively built up. …

Implementing Vertical And Horizontal Engineering Students' Integration And Assessment Of Consequence Academic Achievement, Sarim Al-Zubaidy, Nidhal Abdulaziz, Reza Dashtpour

Faculty of Informatics - Papers (Archive)

Recent scholarship references indicate that integration of the student body can result in an enhanced learning experience for students and also greater satisfaction. This paper reports the results of a case study whereby mechanical engineering students studying at a newly established branch campus in Dubai of a British university were exposed to vertical and horizontal integration. Different activities have been embedded to ensure that students integrated and worked together with their peers and colleagues at different levels. The implemented processes and practices led to improved academic achievements, which were better than those of a similar cohort of students where no …

Dynamic Modelling, Validating And Fine-Tuning Of Engineering Curriculum, Fazel Naghdy

Faculty of Informatics - Papers (Archive)

The undergraduate Engineering schools in Australia are required to embed and assess the Competency Standards defined by the Engineers Australia in their curriculum. At the same time, embedding graduate attributes in the curriculum has become an important element in the quality assurance processes of universities. The embedding and mapping are only the first step in a long term process. The mapping should be validated empirically and reviewed in a repeating cycle towards an effective and optimal curriculum. This will require a rigorous action learning process for creating and cyclic validation of a living curriculum. The conceptual development and early stages …

Reflecting On Ontologies Towards Ontology-Based Agent-Oriented Software Engineering, Ghassan Beydoun, Brian Henderson-Sellers, Jun Shen, G. Low

Faculty of Informatics - Papers (Archive)

“Ontology” in association with “software engineering” is becoming commonplace. This paper argues for the need to place ontologies at the centre of the software development lifecycle for multi agent systems to enhance reuse of software workproducts as well as to unify agent-based software engineering knowledge. The paper bridges the state-of-the-art of ontologies research from Knowledge Engineering (KE) within Artificial Intelligence and Metamodelling within Software Engineering (SE). It presents a sketch of an ontology-based Multi Agent System (MAS) methodology discussing key roles on ontologies and their impact of workproducts, illustrating these in a MAS software development project for an important application …

Active Exploration Of Emerging Themes In A Study Of Object-Oriented Requirements Engineering: The 'Evolutionary Case' Approach, Linda L. Dawson

Faculty of Informatics - Papers (Archive)

The evolutionary case approach provides a framework for qualitative case study research in information systems (IS). It uses revelation, reinforcement, reflection and re-examination to explicitly explore emerging themes in interpretive case study research.

The method is based on the progressive development of a theoretical model grounded initially in the literature and then refined using sequential case studies grounded in practice. The method addresses the gap which often separates data from conclusions in qualitative case study research by documenting the “revealed” and “reinforced” changes in the theoretical model as it evolves from the empirical data.

The paper provides an illustrative study …

Issues Affecting Power Engineering Undergraduate Education In Australia, D A. Robinson, Victor J. Gosbell

Faculty of Informatics - Papers (Archive)

Recent changes to the electric power industry through deregulation and restructuring have had a considerable effect on power engineering education internationally. A number of Australian universities have also noticed a decline in the number of students interested in power engineering subjects, leading to the fewer graduates with power engineering knowledge. With a reduction in graduates and a perception of an aging workforce a shortage of suitably qualified power engineers for industry may be imminent. This paper provides discussion on the current status of university power engineering education within Australia and includes results from a recent Australia-wide survey of the university …

Assessing The Future Of Electrical Power Engineering: A Report On Electrical Power Engineering Manpower Requirements In Australia, Victor J. Gosbell, D A. Robinson

Faculty of Informatics - Papers (Archive)

In 2001 the Electric Energy Society of Australia (EESA) developed concerns based on anecdotal evidence that there was a looming shortage of electrical power engineers in Australia. Information from the electrical power industry and academic communities was obtained through two separate survey questionnaires, a discussion workshop, and a number of submissions. This information was collated and compiled into 'Assessing the Future of Electrical Power Engineering: a Report on Electrical Power Engineering Manpower Requirements in Australia'.

Behavioural Modelling Of High Temperature Superconducting Wires And Coils For Power Engineering Applications, Thomas Hardjono, Christopher David Cook, Sarath Perera

Faculty of Informatics - Papers (Archive)

Many aspects of the behaviour of high temperature superconducting (HTS) wires are well understood for dc applications. However, models of HTS suitable for use in circuit analysis by power engineers designing HTS applications are not readily available. This paper describes the initial development of suitable models for HTS wire. The V-I characteristics for wires carrying dc transport current can be empirically determined using a power law V=kIn. Experimentally measured V-I characteristics are fitted using the above power law. This enables the simulation of the behaviour of Bi-2223/Ag wire using the well-known circuit simulator PSpice. Other factors affecting the dc critical …
