Peepholes are virtual windows to large workspaces. Using a peephole provides an intuitive interface onto information spaces too large to be viewed on the screen of a mobile device. To date, these peephole systems have relied on tethered tracking devices ...

We propose a probabilistic movement model for controlling ant-like agents foraging between two points. Such agents are all identical, simple, autonomous and can only communicate indirectly through the environment. These agents secrete two types of ...

This paper presents a method for converting unrestricted fiction text into a time-based graphical form. Key concepts extracted from the text are used to formulate constraints describing the interaction of entities in a scene. The solution of these ...

The importance of properly securing an organization's information and computing resources has become paramount in modern business. Intrusion detection systems in particular have an increasingly valuable role to play: as networks grow and more ...

In recent years, intensive debate has raged over the significance of knowledge management within the business context. The adoption of knowledge management as a business imperative has relied heavily on its ability to deliver tangible value to ...

Intrusion in information systems is a major problem in security management. Present-day intrusion detection systems detect attacks too late to counter them in real-time. Several authors in the digital forensics literature have proposed using Boyd's ...

A decision-supporting framework was applied in a pilot study to assist in the decision making about what software development methodology to use at a software engineering company. This paper critically assesses this decision making process and framework ...

Reading and understanding algorithms is not an easy task and often neglected by educators in an introductory programming course. One proposed solution to this problem is the incorporation of a technological support tool to aid program comprehension in ...

The case for chip multiprocessor (CMP) or multicore designs is strong, and increasingly accepted as evidenced by the growing number of commercial multicore designs. However, there is also some evidence that the quest for instruction-level parallelism, ...

The research presented in this paper evaluates genetic programming (GP) as a means of evolving pushdown automata. Each pushdown automaton is represented as a directed graph. Tournament selection is used to select parents during each generation and the ...

Search engines facilitate efficient discovery of information in large information environments such as the Web. As the amount of information rapidly increases, search engines require greater computational resources. Similarly, as the user base increases ...

Over a period spanning approximately twenty five years IS researchers have been plagued by the problem of how to evaluate IS effectiveness or success. After the advent of the WWW in the 1990s, questions have arisen regarding the relevance of previously ...

This paper critically evaluates the use of revolutionary and evolutionary theories of scientific method, respectively those of two prominent 20^th century philosophers, Thomas Kuhn and Karl Popper, to account for change in software engineering ...

This paper describes a first attempt at automatically inducing object-oriented programs. The system implemented for this purpose uses a rule-based expert system to firstly derive an object-oriented design (OOD) for the problem instance. Input to the ...

Identity and Access Management (IAM) is an emerging solution for authenticating and authorising individuals. This begins with determining an individual's 'identity' through identification and verification processes. Then it becomes vital for every ...

Usability evaluation of e-learning applications is a maturing area, which addresses interfaces, usability and interaction from human-computer interaction (HCI) and pedagogy and learning from education. The selection of usability evaluation methods (UEMs)...

With the information revolution that promises to shape the 21st century, knowledge has become the prime commodity, very much like land, means of production and capital have been at different times in the past. Access to information, made instantly ...

Technology adoption models specify a pathway of technology acceptance from external variables to beliefs, intentions, adoption and actual usage. Mobile phone adoption has been studied from a variety of perspectives, including sociology, computer-...

New methods, methodologies and procedures are often introduced within information systems without discussing the effectiveness thereof. We investigate the effectiveness of a requirements elicitation procedure for deriving process model structures. There ...

The identification of process model structures is usually complex and costly. If these structures can be reused across boundaries, this could not only benefit the internal structure of one application domain, but could also benefit organizations where ...

Protecting access to data that can be linked to an individual (or personal identifiable information (PII)), thereby seeking to protect the individual's privacy can be accomplished through legislation, organisational safeguards, and technology. Of ...

Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system performance for a specific system ...

One of the key factors affecting the growth of e-commerce is the lack of Internet users' confidence in online information privacy. Despite the importance of understanding the nature of the Internet users' concerns for information privacy, this topic is ...
