Globally there is movement in the trajectory of developing a Global Open Science Cloud (GOSC) aimed at supporting research collaborations across continents to assist in addressing global science challenges - for example UN Sustainable Development Goals (SDGs), climate change, infectious diseases, and coordination of global disaster risk reduction.
Continents, regions, and countries are also...
The non–orthogonality of the United Nation’s Sustainable Development Goals (SDG), their spatio–temporal variations and complex interactions entail concerted interdisciplinary efforts to identify and address triggers of their indicators. As the SDG span across the entire spectrum of human existence, they are naturally associated with data deluge–hence the likelihood of operating around unseen,...
Database forensics, is a branch of digital forensic science that allows forensic examination of databases to be conducted by following normal digital investigation, processes. Regardless, while conducting investigation processes on databases, the aim is always directed towards the extraction of Potential Digital Evidence (PDE) in a forensically sound manner. More often than not, forensic...
The convergence among researchers on the value of data sharing continues to grow yet little data sharing occurs. Several studies exist to understand motivations, perceptions, practices and barriers to research data sharing with seemingly similar findings. One of the key barriers to data sharing is privacy concerns. Not all data can be made publicly accessible. Research data should be made ‘as...
The devastating impact of climate change, based primarily on the overuse of fossil fuels, has increased awareness of and interest in renewable energy. This awareness is increased by recent problems in South Africa, among other nations. Renewable energy sources face the “energy trilemma" of energy supply, economics, and environmental concerns that must be addressed through an optimal...
Cyber-Physical Systems (CPS) [1] are key building blocks of the fourth industrial revolution. They consist of ICT systems that are embedded in the physical objects we manipulate daily, as well as in our environment to provide an interface to the physical world. It is predicted that with the advances made in the Internet-of-Things, Next Generation Networking, Cloud computing and Artificial...
The Intergovernmental Panel on Climate Change (IPCC) Assessment Report six (AR6) shows that much of the globe will experience water and food insecurity, wellness challenges, and damage to infrastructure due to climate change. There is therefore a need for long term observation networks that that can provide clear information on the scale of the problem. Africa and the Southern hemisphere,...
Seasonal Auto-Regressive Integrated Moving Average with exogenous factors (SARIMAX) has shown promising results in modeling small and sparse observed time-series data by capturing linear features using independent and dependent variables. Long short-term memory (LSTM) is a promising neural network for learning non-linear dependence features from data.
With the increase in wildlife...
With the affordances and advancement of Artificial Intelligence-based systems and machines, the application and relevance to multiple fields and disciplines have been ever-increasing. The application of Artificial Intelligence (AI) in multiple sectors, if not every sector, is indicative of its broad spectrum of uses. In very broad terms, AI is “intelligence” displayed by machines that mimic...
Healthcare firms need to respond faster to the rapidly changing threat landscape. Risks to patient privacy and safety are increasing due to recent cyber-attacks. Healthcare firms are lagging in building cybersecurity capabilities prescribed by best practice approaches. This case study aims to identify the barriers to building a dynamic cybersecurity capability within a South African healthcare...
There is a lot of data that is collected and available on many systems. This data could be collected
by certain systems and users could knowingly or unknowingly be sharing the data. Nowadays
with high cases of cybercrime as many users are accessing services online, the issues of data
management become critical. On the other hand, users do not want to provide same data on
related systems...
