(MDPI, 2022-01)Internet of Things (IoT) is the network of physical objects for communication and data sharing. However, these devices can become shadow IoT devices when they connect to an existing network without the knowledge of the ...
-
(Springer, 2021-11)Selection hyper-heuristics have proven to be effective in solving various real-world problems. Hyper-heuristics differ from traditional heuristic approaches in that they explore a heuristic space rather than a solution ...
-
(Wiley, 2022-01)For businesses to benefit from the many opportunities of cloud computing, they must first address a number of security challenges, such as the potential leakage of confidential data to unintended third parties. An inter-VM ...
-
(Institute of Advanced Engineering and Science, 2021-12)Patterns for the internet of things (IoT) which represent proven solutions used to solve design problems in the IoT are numerous. Similar to object-oriented design patterns, these IoT patterns contain multiple mutual ...
-
(JMIR Publications, 2021-04-29)BACKGROUND : The prevalence of chronic conditions such as obesity, hypertension, and diabetes is increasing in African countries. Many chronic diseases have been linked to risk factors such as poor diet and physical ...
-
(MDPI, 2021-03-18)The increasing strain on ageing generation infrastructure has seen more frequent instances of scheduled and unscheduled blackouts, rising reliability on fossil fuel based energy alternatives and a slow down in efforts ...
-
(Elsevier, 2022-03)Usually, real-world time-series forecasting problems are dynamic. If such time-series are characterized by mere concept shifts, a passive approach to learning become ideal to continuously adapt the model parameters whenever ...
-
(Elsevier, 2022-01)In most applications, anomaly detection operates in an unsupervised mode by looking for outliers hoping that they are anomalies. Unfortunately, most anomaly detectors do not come with explanations about which features make ...
-
(Elsevier, 2022-01)The increased amount of high-dimensional imbalanced data in online social networks challenges existing feature selection methods. Although feature selection methods such as principal component analysis (PCA) are effective ...
-
(Cosmos and History Publishing Co-op, 2020-10)In this survey contribution, which extends [GBa19], we consider and discuss computer simulations from a variety of perspectives with particular attention to computer simulations in astrophysics and cosmology. We begin by ...
-
Model checking safety and liveness via k-induction and witness refinement with constraint generation (Elsevier, 2020-12)In this article, we revise our constraint-based abstraction refinement technique for checking temporal logic properties of concurrent software systems. Our technique employs predicate abstraction and SAT-based three-valued ...
-
(Elsevier, 2020-08)Quantification of the stationary points and the associated basins of attraction of neural network loss surfaces is an important step towards a better understanding of neural network loss surfaces at large. This work proposes ...
-
(Springer, 2020-11)This paper extends a PSO-based nonlinear regression technique to dynamic environments whereby the induced model dynamically adjusts when an environmental change is detected. As such, this work hybridizes a PSO designed for ...
-
(Springer, 2020-10)Traditionally search techniques explore a single space to solve the problem at hand. This paper investigates performing search across more than one space which we refer to as bi-space search. As a proof of concept we ...
-
(MDPI, 2021-06)Optimisation has been with us since before the first humans opened their eyes to natural phenomena that inspire technological progress. Nowadays, it is quite hard to find a solver from the overpopulation of metaheuristics ...
-
(Springer, 2021-04)While privacy-enhancing solutions for car-to-car communication are increasingly researched, end user aspects of such solutions have not been in the focus. In this paper, we present a qualitative study with 16 car drivers ...
-
(Springer, 2020-08)Constructions of science that slowly change over time are deemed to be the basis of the reliability with which scientific knowledge is regarded. A potential paradigm shift based on big data is looming – many researchers ...
-
(South African Institute of Computer Scientists and Information Technologists, 2020)In the context of the AISSAC seminar on information systems, to which this invited lecture was given, it is presumed throughout the following considerations that: • contemporary information systems are software systems, ...
-
(Academy of Science of South Africa, 2021-05)The future of a country like South Africa is predicated upon policies; whether these policies are effective or ineffective is not primarily an issue. The prospects and realities of the Fourth Industrial Revolution (4IR) ...
-
(Committee on Data for Science and Technology (CODATA), 2020-05)The coronavirus disease (COVID-19), caused by the SARS-CoV-2 virus, was declared a pandemic by the World Health Organization (WHO) in February 2020. Currently, there are no vaccines or treatments that have been approved ...
