Foundation software engineering practices for capstone projects and beyond

This paper outlines an introductory course in software engineering undertaken by computing students at Deakin University. The course focuses on areas of that are often not emphasized in introductory software engineering. These areas include formal problem solving, management of software development, communication, and working in groups. The approach includes the application of concepts in a collaborative group setting. Enhancements to the course have been made over a number of semesters and evidence suggests that our overall approach is working. The skills acquired by students taking this course can be applied to later courses in software engineering, particularly the capstone project course, and to professional life

Solar aided power generation from coal fired power stations: THERMSOLV software

Although the thermodynamic advantages of using solar energy to replace the bleed off steam in the regeneration system of Rankine cycle coal fired power stations has been proven theoretically, the practical techno/economic feasibility of the concept has yet to be confirmed relative to real power station applications. To investigate this concept further, a computer modelling software “THERMSOLV” was developed by Deakin University researchers, together with the support of the Victorian power industry and Australian Research Council (ARC). This newly developed software simulates the steam cycle to assess the techno/economic merit of the solar aided concept for various power station structures, locations and local electricity market conditions. Two case studies, one in Victoria Australia and one in Yunnan Province, China, have been carried out to show the application of the software. This paper reports the structure and functions of the software, and the results of the two case studies.

Automatic refinement of user requirements : a case study in software tool evaluation

This paper presents an assessment of system effectiveness in automatic requirements refinement by comparing results obtained from experts and novices with those achieved by the system. As the investigated system was a combination of a tightly inter-connected methods and a tool, the evaluation framework melded together a number of distinct methodological approaches structured into three empirical studies, which aimed at the construction of a case problem domain, calibrating the system using this defined domain elements and finally using the calibrated system to assess its effectiveness. In consequence, it was concluded that the evaluated methods and tools were effective in supporting requirements refinement.

Assessment management using software

Web based learning is providing new and innovative environments to facilitate the delivery of course material to increasing numbers students, but most of the effort is centered around the presentation of the learning material and creating environments where student interact with this material and each other. Despite the changes the web based learning environments have delivered, little attention has been given to improving the management and process of assessment. This paper introduces a new software application designed to take advantage of the web based environments and addresses the management overheads associated with assessment whilst improving the feedback to students. Initial investigations indicate significant benefits can be achieved by using software to manage the assessment process. A detailed description of the software is provided and two case studies presented that highlight the software's application and confirmed benefits when used to conduct and manage assessments.

Synergy : a comprehensive software distributed shared memory system

Considerable research and development has been invested in software Distributed Shared Memory (DSM). The primary focus of this work has traditionally been on high performance and consistency protocols. Unfortunately, clusters present a number of challenges for any DSM systems not solvable through consistency protocols alone. These challenges relate to the ability of DSM systems to adjust to load fluctuations, computers being added/removed from the cluster, to deal with faults, and the ability to use DSM objects larger than the available physical memory. This paper introduces the Synergy DSM System and its integration with the virtual memory, group communication and process migration services of the Genesis Cluster Operating System.

Flowchart software for a modular robot

Flowcharting is a common method of setting out the requirements for a piece of code. It is simple with few rules to follow. Rarely however, is it used as the code itself. This paper describes the outline of a software package that uses the flowchart as the code for a small, autonomous, modular robot, designed for use in High Schools and Universities at an introductory level. By using flowcharting the student is introduced to the concept of structured programming. A flowchart is often the first step in programming. Here it is the only step, easing the student into the art of coding, and simplifying the teachers job.

Software warehouse and software mining : the impact of data mining to software engineering

Automating Software Engineering is the dream of software Engineers for decades. To make this dream to come to true, data mining can play an important role. Our recent research has shown that to increase the productivity and to reduce the cost of software development, it is essential to have an effective and efficient mechanism to store, manage and utilize existing software resources, and thus to automate software analysis, testing, evaluation and to make use of existing software for new problems. This paper firstly provides a brief overview of traditional data mining followed by a presentation on data mining in broader sense. Secondly, it presents the idea and the technology of software warehouse as an innovative approach in managing software resources using the idea of data warehouse where software assets are systematically accumulated, deposited, retrieved, packaged, managed and utilized driven by data mining and OLAP technologies. Thirdly, we presented the concepts and technology and their applications of data mining and data matrix including software warehouse to software engineering. The perspectives of the role of software warehouse and software mining in modern software development are addressed. We expect that the results will lead to a streamlined high efficient software development process and enhance the productivity in response to modern challenges of the design and development of software applications.

Flowchart and kernel software for modular robot

Flowcharting is a common method of setting out the requirements for a piece of code. It is simple with few rules to follow. Rarely however, s it used as the code itself. This paper describes the outline of a software package that uses the flowchart as the code for a small, autonomous, modular robot, designed for use in High Schools. It also describe the code used by the robot to complement the flowchart software creating a system that can be used by students and their teachers to design, build and program a robot without previous programming experience.

Global software development : the next RE frontier?

Requirements Engineers face an emerging set of challenges, which compound the traditional Requirements Engineering (RE) challenges (stakeholder identification, domain expertise, communication, analytic skills, problem solving, ...) that have arguably still not been fully addressed. This is the challenge of RE in the world of global software development, with requirements teams working in virtual mode (possibly on different continents), with the software having to operate in multiple contexts, addressing the needs of different cultures and legal jurisdictions, and having to build sales in different marketplaces. Further the need arises to specify software that is progressively enhanced through regular releases, rather than the “green field” specification of products.

This theoretical paper introduces these challenges, and presents an initial selection of theoretical models, drawn from many and varied source disciplines, which might be employed to gain insight into various features of RE in support of global software development. To illustrate the potential relevance of this selection of models, a longitudinal case study with a recently identified software developer, to follow the specification and subsequent roll-out of a future release of a software product for sale globally, is introduced. Features of the situation faced by that organisation are highlighted, to illustrate the potential relevance of the diverse models that have been identified.

E-entrepreneurship and open source software

As the first stage of a larger project, this paper presents experiences of two e-Entrepreneurs in the light of Open Source Software (OSS) being accepted globally. Unlike proprietary software (such as Windows), OSS comes with its internal details visible to its users. The significant implications of this unique style of software distribution for e-Entrepreneurs are examined. Recommendations arising from the interviews include the need to be technically competent; understanding the reasons behind adopting this strategy; and identifying and addressing customers' requirements. Authors also found similarities between traits (such as being visionary; being responsive to market changes) which make an entrepreneur and e-Entrepreneurs successful.

A fuzzy logic based approach for software testing

How to provide cost-effective strategies for Software Testing has been one of the research focuses in Software Engineering for a long time. Many researchers in Software Engineering have addressed the effectiveness and quality metric of Software Testing, and many interesting results have been obtained. However, one issue of paramount importance in software testing — the intrinsic imprecise and uncertain relationships within testing metrics — is left unaddressed. To this end, a new quality and effectiveness measurement based on fuzzy logic is proposed. Related issues like the software quality features and fuzzy reasoning for test project similarity measurement are discussed, which can deal with quality and effectiveness consistency between different test projects. Experiments were conducted to verify the proposed measurement using real data from actual software testing projects. Experimental results show that the proposed fuzzy logic based metrics is effective and efficient to measure and evaluate the quality and effectiveness of test projects.

Agile approaches to software maintenance : an exploratory study of practitioner views

Whilst there has been some research into the application of agile approaches to the world of software maintenance, in this paper it is argued that there has not been a coherent investiga-tion that focuses on the collection and analysis of the views and perceptions of agile software maintenance approaches held by experienced software maintenance professionals. In this paper, we report such an exploratory investigation, which has seeded the development of a simple framework for classifying collected views and perceptions. Specifically, a matrix framework has been introduced, to facilitate comparison of the levels of understanding of the issues affecting an agile adoption decision, and the extent to which an agile approach has been implemented. Examples of organizations operating in all four cells of this matrix have been presented.
