In the process of a radio network design, the propagation loss estimation is a subject of crucial importance in order to meet the demanded quality-of-service. In terrestrial radio-links, propagation loss is usually caused mostly by free space dispersion and diffraction across the geographical obstacles. Thus, the diffraction phenomenon is an unavoidable issue on courses of radio-communications. Therefore, instead of a professional radio-software, it is convenient for educational purposes to develop a simpler radio-simulation tool, but such that elucidates thoroughly the particular stages of the path-loss estimation. Therefore, a computer simulation of approximate methods concerning multiple-diffraction was developed in MATLAB.

The quantity of information/data in the world is increasing exponentially. This is no longer the question of quantity, but how to find and deliver them, in order to make them useful to the user. Information is getting more difficult to locate, gather, filter, evaluate and integrate. This paper's goal is to present the current state at the intelligent agents' research area, as well as to illustrate them with the examples. It is also based on the main assumption that the users of information databases do not require a vast amount of information. On the contrary, they need the data which correspond better to their requirements and interests. This paper presents the basic characteristics of interactive TV systems. It also describes the usage of personal interactive TV. Functionality of an interactive digital and personal electronic programme guide is described as the example of personalisation.

Term information appears in everyday conversations and media, as well as in numerous references. It is assumed that term information is unambiguous and that those who use it clearly understand its meaning. This paper deals with this subject with an attempt to give one interpretation of the term information. Information, as the phenomenon with numerous implications in the process of communication, is also described in this paper. This, above all, refers to the ways in which the amount of information is being quantified, the existence and influence of the primary information barriers, and several crucial questions concerning the information capacity in different kinds of media.

Motivation is one of the most important components of students' success in the e-learning environment. Some other important factors are ICT skills and internet access. In our study, we investigated how extrinsic and intrinsic motivational factors influenced the success of students in a non-moderated e-learning course on the topic of online communication and psychological aspects of internet use. We also investigated how the success in this course was influenced by students' internet access from home and college and by their experience using computers/internet. The subjects in our study were 477 freshmen students of economics. The results of this study indicated that access to the course from home and extrinsic motivational factors had the greatest influence on the results of the final test delivered to the students after they had read the content of the e-learning course.

This paper describes the Microcosm programme established by the Defence Science and Technology Organisation and University of South Australia that seeks to provide a facility to explore systems integration issues, accelerate the formation of systems engineering competencies, and conduct research into model-based systems engineering. Firstly, the paper outlines the design drivers and long term goals of the programme. This is followed by a description of the Stage One implementation that covers the high-level architecture, system design, and implementation. The utility of the Microcosm Sandpit has been successfully demonstrated through a real-time intruder detection and engagement scenario using real and simulated autonomous robot vehicles.

Australia has a skills shortage in the defence industry. Growing demand for complex defence systems highlighted the need for additional systems engineers and systems integration specialists. This is compounded by sustained growth in Australia's resources sector, and competition for engineering professionals. The Skilling Australia's Defence Industry (SADI) initiative provides significant funding for new skills activities. This paper describes one such activity; the creation of a Masters degree in Military Systems Integration (MSI). Designing and implementing the program required some novel educational approaches, to capture the value of industry experience, and integrate critical but elusive aspects that require tacit knowledge transfer.

This paper summarises the use of a competency-based approach to assess our university's systems engineering curriculum. Our team selected and validated a systems engineering competency model developed from within the space industry to perform an assessment of our core systems engineering courses. Next, we assessed the level to which a student successfully completing our programme, could potentially 'apply', with minimal guidance, those systems engineering capabilities we defined as critical. We identified the gaps or opportunity areas for improvement in our curriculum and based on these gaps, we developed an initial set of actions for improving our core systems engineering curriculum.

This paper critiques a previous attempt at methodology selection for R&D environments, and on the basis of the findings of this critique proposes the development of a multi-stream meta-methodology to apply systems engineering to the development of software intensive systems in R&D environments. This methodology is intended to provide expert support to inexperienced project managers leading R&D projects, providing a just-in-time, on-demand training resource. The paper describes an interactive prototype tool for guiding users through this meta-methodology.

Doctoral degrees have been structured, traditionally, as PhDs with emphasis on training the candidate to perform research into topics relevant to the discipline. Professional doctorates were developed to provide doctoral level education to enable their graduates to practice in their field with exceptional competence. In engineering the idea of professional doctorates is relatively new, and has been heavily influenced by the concept of the research embodied in engineering PhDs, with the degree structure modified to include substantial coursework. This paper describes the professional doctorate in engineering offered at the University of South Australia, in particular showing the application of an approach to professional practice which is itself research.

Systems engineering is a life cycle approach to engineering design: the integration of numerous technical and non-technical disciplines toward the development of new products, systems and services. This paper describes the experiences of the authors in designing and implementing a three-year project to engage high school classes in a geographically-distributed systems engineering design project that addresses relevant, social challenges of interest to students worldwide. Collaborating with others around the world to develop a solution to an engineering problem, students are introduced to systems-thinking, team work, effective communication and other 21st century workforce skills. This innovative project aims to increase the number of students interested in pursuing engineering as a career and to increase the pool of teachers familiar with engineering design and systems thinking.
