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 thermochemical conversion of waste tires for chemicals and power production is investigated using process synthesis techniques and experimental analysis. Pyrolysis and gasification technologies were evaluated in terms ...
Industrialization has resulted in the introduction of xenobiotics into the environment.
These chemicals have polluted soil, water, and air, causing significant health concerns.
White rot fungi possess the capability to ...
Municipal wastewater pollution in developing countries is a great concern due to partially treated or untreated wastewater. Inflow and Infiltration (I/I) is a challenge in municipalities that receive stormwater as it impacts ...
The key motivation of the study was to explore and enlarge understanding of the factors that inhibit and drive the performance of the postal sector in a dynamic setting in the context of Southern Africa. This study was ...
This study investigated the implementation techniques that an organisation can follow to advance supply chain process efficiency by integrating lean management and Industry 4.0 initiatives in its procurement process for ...
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 ...
Benzonitrile (C6H5C≡N) is a synthetic nitrile with vast applications as a solvent and intermediate in the manufacturing of drugs, perfumes, dyes, rubber, textiles, agrochemicals, resins, and specialty lacquers. Benzonitrile ...

Abstract
Tannery industries’ effluent contains a high concentration of Cr (VI) which has the potential to affect the environment and public health. Therefore, this study aimed to investigate the optimization ...
Abstract
The tannery industry inevitably generates toxic and catastrophic wastewater, which results in a huge threat to public health and water resources. Therefore, this work aimed to synthesize parthenium ...
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 ...
A vehicle chassis is one of the most vital components of an automobile. It supports various
components like the vehicle body, engine, and suspension and transmission system. The
purpose of heavy-duty motor vehicles (HMV) ...
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 ...
Crude oil is an unrefined petroleum which forms because of dead organisms buried under mud over a long period of time (million years). The mud is then converted to sedimentary rocks, which create intense heat and pressure, ...
The aim of this study was to determine the effects of the feedstock composition, such as biomass, polyethylene and their respective blend ratios, -gasifying agents and operating conditions on the product gas composition, ...
Lead-acid batteries with conventional materials are now no longer able to meet the
emerging requirements for several applications in telecom, automobile, solar, etc., Due to
the increase in the demand for higher ...
