Cryptographic attacks on Internet of Things (IoT) devices are not highly con sidered by the users of IoT. Most cryptographic algorithms commonly used on
IoT devices are vulnerable to cryptographic attacks. Cryptography ...
The use of crushed basalt aggregates as an alternative to sand aggregates
is gaining momentum. This is driven by efforts of ensuring sustainable
developments in shotcrete production. The main objective of this study ...
Electrical energy storage is very important. Energy storage devices such as batteries and
capacitors can be used to store energy.
In this dissertation we investigate the use of a supercapacitor or electric double-layer ...
This paper investigates the effect of the electric double layer capacitor (EDLC) in reducing
stress and prolonging the battery lifespan in a hybrid energy storage system (HESS). A 65 F, 16.2 V
EDLC supercapacitor was ...

Abstract
Heterogeneous photocatalysts have been widely used for the removal of various organic pollutants from wastewater. The main challenge so far resides in the sustainability of the process, with regard ...
In recent years the importance and need for computer vision systems increased due to security demands, self-driving cars, cell phone logins, forensic identification, banks, etc. In security, the idea is to distinguish ...

The idea of a mid-term energy storage system (ESS) is becoming a popular option for
improving the performance of energy conservation, power efficiency and the power grid.
The goal of this research is to explore the ...
The South African power utility, Eskom, and, in turn, the metropolitan and local
municipalities, have difficulty meeting the country's growing demand for electricity. In this
study, electric water heaters have been ...
This paper investigates the characterization of an electric double-layer capacitor (EDLC). In this study, the 300 F and 400 F EDLC supercapacitors are connected in a circuit in a laboratory experiment to produce their ...
Over the past fifty years Valve Regulated Lead Acid (VRLA) battery has been deployed with Uninterruptable Power Supplies (UPS) backup systems as a last line of defense against primary power outages, due to its affordability ...
The worldwide utilisation of renewable energy in electric power systems is growing rapidly due to concerns about the environment and the depletion of the sources of conventional power generation. The Weibull distribution ...
The global warming and realisation that fossil fuel is limited, has been a drive over the years to move to renewable energy sources (RES). Consequently, solar energy and other renewable energy sources are currently being ...
There exists a need to understand the behaviour of wet mill loads by numerical simulation. However, the challenge is to adequately combine solid-based and liquid-based computer algorithms into one realistic framework. This ...
The production of low-carbon energy products from biomass gasification is encouraged,
in order to expand our sources of energy and to mitigate the harmful impact of the pollutants on the climate and the environment. The ...
For research in speech processing and analysis of audio content in general, extensive data sets are
required. Creating such a dataset manually turns out to be time and labour consuming, but it is a
task very suitable ...
