Machinability study of hybrid nanoclay-glass fibre reinforced polyester composites
Glass fibre reinforced polyester composites (GRP) and hybrid nanoclay and glass fibre reinforced polyester nanocomposites (CGRP) are fabricated by vacuum assisted resin infusion technique. The optimum mechanical properties ...
Conceptual framework of environmental sustainable interventions with the use of green infrastructure design criteria on projects
This paper presents a conceptual framework that incorporates eco-efficiency on Infrastructure projects with the use of the environmentally sustainable criteria on infrastructure projects. Mainstreaming environmental ...
Evaluation of combined Pareto multiobjective differential evolution on tuneable problems
Many optimization problems in engineering involve the satisfaction of multiple objectives within the limits of certain constraints. Methods of evolutionary multi-objective algorithms (EMOAs) have been proposed and ...
Influence of effluent type on the performance of chitosan as a coagulant
(Akshar Publications, 2014)
The use of chitosan as a bio-polymeric coagulant has continued to attract interest in water treatment due to its biodegradability and non-toxicity. Its ability to treat effluents of high organic content has been investigated ...
Using computational intelligence
The aim of this study was to assess the efficacy of using artificial neural networks (ANNs) to classify hydration status and predict the fluid requirements of endurance athletes. Hydration classification models were built ...
Controller performance assessment of servomechanisms for nonlinear process control systems
Abstract—This paper aims at assessing the setpoint tracking performance of proportional-integral-derivative (PID) controllers for nonlinear single-input-single-output (SISO) process loops. A comparison is made between the ...
Eco-efficient criteria : sustainability
(3S Media, 2014-04)
There is an urgent need to apply cost-effective technologies and methods that deliver better and more sustainable performances.
Visual assessments of current pavement conditions in the stack areas of Berth 203-205 at the Durban Container Terminal-Pier 2
(Emerald Group, 2014-04)
The Durban Container Terminal is currently the biggest and busiest container terminal in Africa and handles about 2.7-million TEUs a year. DCT handles approx. 70% of South Africa’s containers and generates 60% of South ...
Infrared heating assisted thermoforming of polypropylene clay nanocomposites
The objective of this work is to study the influence of nanoclay addition in PP sheet during infrared (IR) heating assisted thermoforming process. The effect of nanoclay on viscoelastic, friction and dimensional characteristics ...
Difference of hydrodynamics for a VPE with and without mass transfer and effect of agitation level on extent of mass transfer
(The South African Journal of Chemical Engineers (SAJChE), 2013-12-29)
Liquid-liquid extraction offers an alternative separation technique, other than distillation, that uses a solvent for the separation of liquid constituents (Pratt, 1983). The vibrating plate extractor (VPE) is a mechanically ...
