Development of granular-medium-based energy management system for automotive bumper applications
Automotive bumpers are installed primarily to minimize damage and harm to both the automobile and passengers during minor and low speed collisions. The efficacy of the current bumper systems lies in absorbing the impact ...
The effect of biomass acclimation on the co-digestion of toxic organic effluents in anaerobic digesters
Currently KwaZulu-Natal (KZN) province is populated with textile industry, which produces wastewater, some of which is not biodegradable. Due to the stringent environmental regulations the wastewater cannot be discharged ...
Process development for co-digestion of toxic effluents : development of screening procedures
The primary objective of this project was to establish a screening protocol which could be used to access high strength/toxic effluent for toxicity and degradability prior to being disposed in wastewater treatment ...
Towards greener infrastructure
Design optimization of anisotropic pressure vessels with manufacturing uncertainties accounted for
Accurate optimal design solutions for most engineering structures present considerable difficulties due to the complexity and multi-modality of the functional design space. The situation is made even more complex when ...
Buckling and sensitivity analysis of nonlocal orthotropic nanoplates with uncertain material properties
Accurate estimates of the orthotropic properties of nano-materials are usually not available due to the difficulties in making measurements at nano-scale. However the values of the elastic constants may be known with some ...
Melt blend studies of nanoclay-filled polypropylene (PP)–high- density polyethylene (HDPE) composites
The objective of this work is to study how the rheological factors of unfilled and nanoclay-filled HDPE– PP blend series influence the structure, morphology, and mixing characteristics. For this study, a series of HDPE–PP ...
Reuse of cured epoxy as a reinforcement in an epoxy composite
This article discusses the reuse of a thermoset-based epoxy polymer. In this method, cured epoxy polymer is ground to powder of particle size ranging from 1 to 30 μm. The ground epoxy is then filled in an epoxy polymer to ...
Comparison between conditions of major roads within and outside the port of Durban
Over the past years road traffic has increased at the Port of Durban. Due to the lack of maintenance, this has resulted in road deterioration. Roads are considered as the most important transport mode at the Port of Durban. ...
Rea Vaya : South Africa’s first bus rapid transit system
Today, both the public and private transport sectors are facing challenges as a result of an increase in vehicle ownership and the suburbanisation of both firms and residences in the world. In the past, public transport ...
