Effect of nanoclay in HDPE–glass fiber composites on processing, structure, and properties

Mohan, T. P.; Kanny, Krishnan (Taylor and Francishttp://dx.doi.org/10.1080/09243046.2012.736348, 2012-10-23)

Natural Na+ montmorillonite (MMT) microclay and organo-treated MMT nanoclay were independently filled in a high-density polyethylene (HDPE) polymer and HDPE–glass fiber (GF) composite and the rheological and mechanical ...
Chemical treatment of sisal fiber using alkali and clay method

Mohan, T. P.; Kanny, Krishnan (Elsevierhttp://www.sciencedirect.com/science/article/pii/S1359835X12002138, 2012-07-24)

In this study the chemical treatment of sisal fiber using the combined alkali (NaOH) and clay is discussed. The purpose of this fiber treatment is to improve the fiber–matrix compatibility, interface strength, mechanical, ...
Towards greener infrastructure

Saroop, Shian Hemraj; Allopi, Dhiren (IMESAhttp://www.imesa.org.za/, 2012-04)
Use of piezoelectric techniques monitoring continuum damage of structures

Nhassengo, Sikhulile Khululeka (2011)

The objective of the present study was to investigate if piezoelectric techniques or sensors can be used in monitoring structural degradation. The study considers experimental results and analytical modelling of a ductile ...
Use of evaporative coolers for close circuiting of the electroplating process

Munsamy, Megashnee (2011)

The South African electroplating industry generates large volumes of hazardous waste water that has to be treated prior to disposal. The main source of this waste water has been the rinse system. Conventional end-ofpipe waste ...
Separation processes for high purity ethanol production

Ngema, Peterson Thokozani (2010)

Globally there is renewed interest in the production of alternate fuels in the form of bioethanol and biodiesel. This is mainly due to the realization that crude oil stocks are limited hence the swing towards more renewable ...
The purification of corn steep liquor as a fermentation feedstock by ultrafiltration

Govender, Devan (2010)

THE OBJECTIVE of this study was to devise a purification process, using ultrafiltration membranes as the core technology, for the preparation of corn steep liquor (CSL) as a fermentation feedstock. This process inherently ...
A technique for stiffness improvement by optimization of fiber steering in composite plates

Tabakov, Pavel Y.; Walker, Mark (Springerhttp://www.springerlink.com/content/h813074n588177w1/fulltext.pdf, 2010)

A methodology for stiffness improvement by optimal orientation of fibers placed using fiber steering techniques of composite plates has been developed and is described here. A genetic algorithm is employed to determine the ...
A hybrid simulation technique to predict the effects of human deterioration and learning in an industrial environment

Hay, Graeme Kenneth (2009)

Process simulation is an effective tool when used to simulate a system where a great deal of data exists for the process. This technique is however limited when it comes to simulating certain non-deterministic parts such ...
Process development for co-digestion of toxic effluents : development of screening procedures

Dlamini, Sithembile (2009)

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 ...
Development of granular-medium-based energy management system for automotive bumper applications

Maina, Mwangi Festus (2009)

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 ...
Object motion detection, extraction and filtering using ANN ensembles

Moorgas, Kevin Emanuel (2009)

This research is devoted to the development of an intelligent image motion detection system based on artificial neural networks (ANN’s). Object motion detection, non-stationary image isolation and extraction, and image ...
The infrastructure cost planning model : an integrated solution to cost effective design

Saroop, Shian Hemraj (2009)

Infrastructure project costs are being scrutinised more closely and with greater skill and accuracy as projects have become larger, more complex and more expensive, and clients have become more exacting in their requirements. ...
Design and implementation of an intelligent vision and sorting system

Li, Zhi (2009)

This research focuses on the design and implementation of an intelligent machine vision and sorting system that can be used to sort objects in an industrial environment. Machine vision systems used for sorting are either ...
Travel patterns and safety of school children in the eThekwini Municipality

Dhoda, Salma (2009)

The annual incidence of pedestrian casualties on South African roads is approximately 34 000. This includes 4 000 deaths, 10 000 serious injuries and 20 000 minor injuries, costing the country an estimated R2,55 billion. ...
A particle swarm optimization approach for tuning of SISO PID control loops

Pillay, Nelendran (2008)

Linear control systems can be easily tuned using classical tuning techniques such as the Ziegler-Nichols and Cohen-Coon tuning formulae. Empirical studies have found that these conventional tuning methods result in an ...
The development of an advanced composite structure using evolutionary design methods

Van Wyk, David (2008)

The development of an evolutionary optimisation method and its application to the design of an advanced composite structure is discussed in this study. Composite materials are increasingly being used in various fields, ...
The effect of biomass acclimation on the co-digestion of toxic organic effluents in anaerobic digesters

Chamane, Ziphathele (2008)

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 ...
The synthesis, structure and properties of polypropylene nanocomposites

Moodley, Vishnu Kribagaran (2007)

Polymer nanocomposites may be defined as structures that are formed by infusing layered-silicate clay into a thermosetting orthermoplastic polymer matrix. The nanocomposites are normally particle-filled polymers for ...
The in-service determination of the presence of distortion in a high quality analogue sound signal

Mare, Stefanus (2007)

Detecting and minimising distortion in audio signals is an important aspect of sound engineering. Distortion of a signal passing through an audio system may be caused by a number of factors and it is necessary to detect ...
