The Work and Lives of Street Waste Pickers in Pretoria-A Case Study of Recycling in South Africa's Urban Informal Economy

Schenck R.; Blaauw P.F. (2011)

High levels of unemployment are a permanent feature in the urban areas of many developing countries. South Africa is no exception in this regard. Poverty and hardship caused by unemployment force many participants in the ...
A framework for the dynamic implementation of finite automata for performance enhancement

Ketcha Ngassam E.; Watson B.W.; Kourie D.G. (2005)

The aim of this work is to provide a model for the dynamic implementation of finite automata for enhanced performance. Investigations have shown that hardcoded finite automata outperforms the traditional table-driven ...

The effect of time reversal symmetry on vibrational modes in ZnO and related compounds: GaN, CdS, BeO, ZnS, CdSe

Kunert H.W.; Osuch K.; Barnas J. (2005)

Vibrational states of a crystal are classified according to the irreducible representations (irrps) of the corresponding factor groups Gk/T. The wave vector k runs over the entire first Brillouin Zone (BZ). For a hexagonal ...
Reliability characteristics of the Maxwell distribution: A Bayes estimation study

Bekker A.; Roux J.J.J. (2005)

This article presents maximum likelihood. Bayes, and empirical Bayes estimators of the truncated first moment and hazard function of the Maxwell distribution. A comparison of the relative efficiency of these three estimators ...
Hydrolysis of 4-nitrophenyl phosphate in microemulsions assisted by polymetallic complexes: A bio-mimetic model for decontamination of organophosphate pollutants

Tafesse F. (2005)

The hydrolysis of 4-nitrophenyl phosphate (NPP) in the presence of several metal ions and polymetallic complexes in oil-in-water microemulsion was investigated at 10-3 M concentration. The reaction was monitored by measuring ...

Largest family without A ∪ B ⊆ C ∩ D

De Bonis A.; Katona G.O.H.; Swanepoel K.J. (2005)

Let F be a family of subsets of an n-element set not containing four distinct members such that A ∪ B ⊆ C ∩ D. It is proved that the maximum size of F under this condition is equal to the sum of the two largest binomial ...
Towards a finite-state network for Northern Sotho deverbative nouns: The morphotactic rules

Kotze P.M. (2005)

In order to build a lexical transducer which can alternately generate grammatical forms and analyse the constituent parts of grammatical forms, the linguist has to provide the computer specialist with all the grammar rules ...
On weak convergence of iterates in quantum Lp-spaces (p ≥ 1)

Grabarnik G.Ya.; Katz A.A.; Shwartz L. (2005)

Equivalent conditions are obtained for weak convergence of iterates of positive contractions in the L1-spaces for general von Neumann algebra and general JBW algebras, as well as for Segal-Dixmier Lp-spaces (1 ≤ p < ∞) ...
An asymptotic result for the Path Partition Conjecture

Frick M.; Schiermeyer I. (2005)

The detour order of a graph G, denoted by τ (G), is the order of a longest path in G. A partition of the vertex set of G into two sets, A and B, such that τ((A)) ≤ a and τ(〈B〉) ≤ b is called an (a, b)-partition of G. If G ...

Development of the Learning Potential Computerised Adaptive Test (LPCAT)

De Beer, Marie (2005)

An overview of the development of a dynamic test for the measurement of learning potential - the Learning Potential Computerised Adaptive Test (LPCAT) - is provided. The test was developed in South Africa with a view to ...

HIV/AIDS symptom management in Southern Africa

Sukati N.A.; Mndebele S.C.; Makoa E.T.; Ramukumba T.S.; Makoae L.N.; Seboni N.M.; Human, S.P.; Holzemer W.L. (2005)

We describe self-reported strategies used by persons living with HIV/AIDS in Botswana, Lesotho, South Africa, and Swaziland to manage common HIV-related symptoms. A questionnaire asked participants to list three to six ...
Beyond the drip-line: A high-resolution open-air Holocene hunter-gatherer sequence from highland Lesotho

Mitchell P.; Plug I.; Bailey G.; Charles R.; Esterhuysen A.; Lee Thorp J.; Parker A.; Woodborne S. (2011)

The activities of hunter-gatherers are often captured in rockshelters, but here the authors present a study of a riverside settlement outside one, with a rich sequence from 1300 BC to AD 800 Thanks to frequent flooding, ...
Arms Acquisition and Procurement in South Africa: The Socio-History of Arms Deals with Reference to Attitudes, Strengths and Limitations in Decision-Making (1935-1994)
