Towards realistic interactive sand : a GPU-based framework
(2009)
Many real-time computer games contain virtual worlds built upon terrestrial landscapes, in particular, "sandy" terrains, such as deserts and beaches. These terrains often contain large quantities of granular material, ...
Ubiquitous mesh networking : application to mobile communication and information dissemination in a rural context
(2014)
ICT has furthered the social and economic development of societies but, rural African communities have lagged behind due to issues such as sparse population, low household income, a lack of electricity and other basic ...
Internet of things : least interference beaconing algorithms
(2014)
The emerging sensor networking applications are predicting the deployment of sensor devices in thousands of computing elements into multi-technology and multi-protocol platforms. Access to information will be available not ...
Perceptions of cloud computing in the South African government
(2014)
The South African government is unable to provide efficient Information Technology (IT) services to the citizens because of the fragmented approach in government where each department procures their own IT services and ...
Volumetric cloud generation using a Chinese brush calligraphy style
(2014)
Clouds are an important feature of any real or simulated environment in which the sky is visible. Their amorphous, ever-changing and illuminated features make the sky vivid and beautiful. However, these features increase ...
Designing an architecture for secure sharing of personal health records : a case of developing countries
(2014)
While there has been an increase in the design and development of Personal Health Record (PHR) systems in the developed world, little has been done to explore the utility of these systems in the developing world. Despite ...
An agent based layered framework to facilitate intelligent Wireless Sensor Networks
(2011)
Wireless Sensor Networks (WSNs) are networks of small, typically low-cost hardware devices which are able to sense various physical phenomenon in their surrounding environments. These simple nodes are also able to perform ...
Multi-layered security in the Internet of the Things
(2014)
It is well discussed and understood that there is still a need for suitable security for the Internet of Things. It is however still not clear how existing or emerging security paradigms can be effectively applied to a ...
Specification and verification of context conditions for programming languages
(1986)
Context conditions - also called static semantics - are the constraints on computer programs that cannot be reasonably expressed by a context-free grammar, but that can be statically checked without considering the execution ...
Incremental volume rendering using hierarchical compression
(1996)
The research has been based on the thesis that efficient volume rendering of datasets, contained on the Internet, can be achieved on average personal workstations. We present a new algorithm here for efficient incremental ...
