Usability, which is generally defined in terms of application effectiveness, efficiency and user satisfaction, is one of the focus areas of human-computer interaction (HCI). Accessibility is the design of systems that can be perceived, understood and ...

Information and Communication Technologies (ICT) practitioners are often located in the social sciences branch of Information Systems (IS). Practitioner research comprises of research that practitioners undertake with a view to the advancement of their ...

Recent advancements in Text-to-Scene research have lead to the development of systems which automatically extract key concepts from the text of a fiction book and generate computer animated movies depicting the story. Extracting such annotations from ...

The purpose of this paper is to explore components that influence the Mobile User Experience (MEX) in a mlearning interaction through a review of relevant literature. The application of mobile cellular technology in education has been the focus of the ...

Monitoring systems are necessary for the management of anything beyond the smallest networks of computers. While specialised monitoring systems can be deployed to detect specific problems, more general systems are required to detect unexpected issues, ...

The validation of a software specification may be viewed as a function of what the specification is to be used for and any comprehensive validation exercise needs to address possibly conflicting requirements. In this paper we develop a framework which ...

Economic activities in rural areas of developing countries are usually not strong enough to impact significantly in poverty alleviation and improve rural life. These communities are often marginalized in terms of basic infrastructures; low economic ...

This paper investigates mobile phone adoption by older adults to better understand this user group's current level of adoption and to assess how well existing adoption models capture the acceptance levels of elderly users. The rationale is that mobile ...

There are several sources that indicate a remarkable increase in the adoption of open source software (OSS) into the technology infrastructure of organizations. In fact, the number of medium to large organizations without some OSS installations, is ...

The SASL project at the University of the Western Cape is in the process of creating a machine translation system on mobile phones that can automate the translation process between English and South African Sign Language (SASL). This will supplement the ...

Digital Doorways are rugged computer terminals that offer unassisted learning and peer-assisted learning of basic computer skills, as well as a range of computing activities from entertainment, through education, to independent research. Sites are ...

PH2 is an Hadoop and SQL-based tool for extracting information out of the Protein Database (PDB) quickly. The PDB database is stored as a set of Hadoop sequence files in a replicated way on the Hadoop Distributed File System. PH2 then allows a user to ...

Today's mobile computing devices provide a convenient means to search for points-of-interest (POIs) such as restaurants and accommodation. These devices, however, have several design constraints including limited screen space and hardware capabilities. ...

The penetration of mobile phones and mobile technologies in developing countries has led to innovative developments of various m-Health applications. These applications have proven the potential of mobile technologies for improving the quality of health ...

User expertise and skill affects the way users interact with software. It is envisaged that an adaptive user interface (AUI) which dynamically changes from a novice user interface (UI) to an expert UI could possibly improve users' performance. Contact ...

The Information Technology (IT) subject presented in South African secondary schools is considered to be a difficult subject. The programming component of IT is believed to be the main cause of this difficulty. Learners who struggle with programming are ...

This paper investigates the move from philosophical ontology to information systems ontologies. Ontology has traditionally been (and still is) a philosophical discipline that studies the nature of existence. In a certain time and philosophical era, ...

Many problems in the world exists where it is necessary to compare a given implementation with a specification and provide some quantification as to whether the implementation complies with the specification. An example of such a problem is determining ...

Small Medium and Micro Enterprises (SMMEs) have become active instruments for poverty alleviation, employment generation as well as economic and social development. However, SMMEs in developing countries operate under effervescent business environments ...

The rapid growth and development of wireless communication services and applications corresponds to an increase in associated energy consumption. For broadband wireless network deployment in rural areas affected by unreliability and unavailability of ...

The accent with which words are spoken can have a strong effect on the performance of a speech recognition system. In a multilingual country such as South Africa where English is not the first language of most citizens, the need to address this issue is ...

Employees of companies are often unable to work securely, because they lack knowledge in the field of Information Security.

This paper is based on the premise that a computer game could be used to educate employees about Information Security. A game was ...

An important challenge facing e-Science is the development of scalable systems and analysis techniques that allow client applications to locate data and services in increasingly large-scale distributed environments. e-Science Systems should achieve ...

Previous work on implementations of FA-based string recognizers suggested a range of implementation strategies (and therefore, algorithms) aiming at improving their performance for fast string recognition. However, an efficient exploitation of suggested ...

In the domain of network security, packet filtering for classification purposes is of significant interest. Packet classification provides a mechanism for understanding the composition of packet streams arriving at distinct network interfaces, and is ...

This paper describes an experimental study to compare the performance of various dynamically resizable bit-vector implementations for the C++ programming language.

We compare the std::vector<bool> from the Standard Template Library (STL), boost::dynamic_...

A hyper-heuristic for the examination timetabling problem searches a space of constructive heuristic combinations instead of a space of examination timetables. The most optimal heuristic combination found by the search is used to construct the ...

Research in the domain of school timetabling has not developed as rapidly as other areas of educational timetabling such as university course and examination timetabling. A lot of research has been conducted into using hyper-heuristics to solve the ...
