The use of computer-generated crowds in visual effects has grown tremendously since the warring armies of virtual ores and elves were seen in The Lord of the Rings. These crowds are generated by agent-based simulations, ...

The challenge of parking management has increasingly posed the need for smart solutions. Motorists in today's busy world seek the best option in locating available parking points. The need for an efficient parking system ...

The methods of transmitting information may be divided as follows: direct; and, indirect. The âdirectâ method occurs when a creature transmits a signal that other creatures in its local environment can receive. Word of ...

When facilitating decisions in which some performance evaluations are uncertain, a decision must be taken about how this uncertainty is to be modelled. This involves, in part, choosing an uncertainty format {a way of ...

Data discovery and data handling often presents serious challenges to organizations that manage huge archives of raster datasets such as those generated by satellite remote sensing. Satellite remote sensing produces a ...

Fetal Alcohol Spectrum Disorder (FASD) is the most common form of preventable mental retardation worldwide. This condition affects children whose mothers excessively consume alcohol whilst pregnant. FASD can be identified ...

The application of information and communication technologies to development (ICT4Dev) is widely believed to have the potential to improve livelihoods in developing regions. Within the field of HCI, it is recognised that ...

3G is the wireless network technology expected to allow wireless applications to perform on par with wired applications. However 3G has factors which limit its performance. These factors include both device factors such ...

The major part of this thesis focuses on investigating dynamic hydration behaviour of a series of hexacycylic molecules in water, by using computational techniques validated through ultrasound interferometry experiments. ...

This paper revisits the problem of Quality of Service (QoS) provisioning to assess the relevance of using multipath routing to improve the reliability and packet delivery in wireless sensor networks while maintaining lower ...

Universities in developing nations are viewed as gateways to global knowledge and as the source of human capital for their countries' economies (Juma, 2008). However, these universities face challenges in accessing educational ...

Many universities, libraries, government organisations and companies are implementing digital repositories to collect, preserve, administer and distribute their collections via the World Wide Web. In the process of building ...

We designed and developed a Collaborative Annotation System for Proteins called DAS Writeback, which extends the Distributed Annotation System (DAS) to provide the functionalities of adding, editing and deleting annotations. ...

The preferred method of communication amongst Deaf people is that of sign language. There are problems with the video quality when using the real-time video communication available on mobile phones. The alternative is to ...

Wireless local and metropolitan area network (WLAN/WMAN) technologies, more specifically IEEE 802.11 (or wireless fidelity, WiFi) and IEEE 802.16 (or wireless interoperability for microwave access, WiMAX), are well-suited ...

For any technology to become widely-used and accepted, it must support end-user authoring and customisation. This means making the technology accessible by enabling understanding of its design issues and reducing its ...

Visualizations that show the shape of and spatial relationships between layers of surfaces are useful to oceanographers studying water masses or oncologists planning radiation treatments. The shape of and distances between ...

The phenomenal emergence of several heterogeneous wireless networks and technologies has allowed users to have access to IP services anywhere, at anytime, from any network and with whatever terminal they use. This computing ...

Web applications are usually installed on and accessed through a Web server. For security reasons, these Web servers generally provide very few privileges to Web applications, defaulting to executing them in the realm of ...

This thesis situates digital storytelling in rural African communities to enable rural people to record and share their stories and to express their imaginations digitally. We explore the role of design and the methods and ...
