Adoption of a visual model for temporal database representation
(2016)
Today, in the world of information technology, conceptual model representation of database schemas is challenging for users both in the Software Development Life Cycle (SDLC) and the Human-Computer Interaction (HCI) domain. ...
Accelerated deconvolution of radio interferometric images using orthogonal matching pursuit and graphics hardware
(2016)
Deconvolution of native radio interferometric images constitutes a major computational component of the radio astronomy imaging process. An efficient and robust deconvolution operation is essential for reconstruction of ...
Understanding merchant adoption of m-payments in South Africa
(2016)
Despite the proliferation of mobile communication technology and smartphone adoption, a number of barriers, most notably trust and security, and the lack of critical mass, have slowed the uptake of mobile payments (m-payments). ...
Automating user privacy policy recommendations in social media
(2016)
Most Social Media Platforms (SMPs) implement privacy policies that enable users to protect their sensitive information against privacy violations. However, observations indicate that users find these privacy policies ...
Determining the optimal protocols for transfer of large data files
(2015)
The transfer of large data files remains a necessity for scientific research, including Bioinformatics, despite alternate solutions like cloud computing. When transferring large files, there are many transfer protocols to ...
An empirical evaluation of evolutionary controller design methods for collective gathering task
(2015)
This research aims to evaluate the performance of evolutionary controller design methods for developing a collective behaviour for a team of robots. The methods tested in this research are NEAT which is capable of finding ...
Decoupled Sampling for Real-Time Graphics Pipelines
(2010-03-29)
We propose decoupled sampling, an approach that decouples shading from visibility sampling in order to enable motion blur and depth-of-field at reduced cost. More generally, it enables extensions of modern real-time graphics ...
Performance and error analysis of three part of speech taggers on health texts
(2010-02-25)
Increasingly, natural language processing (NLP) techniques are being developed and utilized in a variety of biomedical domains. Part of speech tagging is a critical step in many NLP applications. Currently, we are developing ...
Automatic Parallelization With Statistical Accuracy Bounds
(2010-02-10)
Traditional parallelizing compilers are designed to generate parallel programs that produce identical outputs as the original sequential program. The difficulty of performing the program analysis required to satisfy this ...
Relational Cloud: The Case for a Database Service
(2010-03-14)
In this paper, we make the case for â databases as a serviceâ (DaaS), with two target scenarios in mind: (i) consolidation of data management functionality for large organizations and (ii) outsourcing data management ...
