Lie group classification of the generalized Lane-Emden equation
(Elsevier http://dx.doi.org/10.1016/j.amc.2009.01.008, 2009)
We carry out the Lie group classification of the generalized Lane–Emden equation
xu00 þ nu0 þ xHðuÞ ¼ 0, which has many applications in mathematical physics and astrophysics.
We show that the equation admits a three-dimensional ...
Lagrangian approach to a generalized coupled lane-Emden system: symmetries and first integrals
(Elsevier http://www.sciencedirect.com/science?_ob=ArticleListURL&_method=list&_ArticleListID=1120288190&view=c&_acct=C000043160&_version=1&_urlVersion=0&_userid=778200&md5=2911144ac0b419d4936d24596384b313, 2009)
This paper aims to classify a generalized coupled Lane–Emden system and to compute the
Noether operators corresponding to a Lagrangian for a generalized coupled Lane–Emden
system which occurs in the modelling of several ...
Review of analysis methods for inelastic design of steel semi-continuous frames
(Elsevier http://www.linkinghub.elsevier.com/retrieve/pii/S0143974X05001057, 2006)
Three groups of methods for the inelastic analysis of steel plane frames with semi-rigid joints are considered in this paper. The first one
consists of simplified second-order (or P–Δ) plastic-hinge methods for the ...

Analysis of gender differences in education for engineering career (Gaborone case study)
(University of Botswana, 2000)
The percentage of students, especially women in engineering, is very low in Botswana and the country is still heavily dependent upon foreign human resources.The objective of this research has been to study the gender ...
Lessons and challenges encountered in the implementation of solar energy – the case of Botswana
(Bentham Open http://www.bentham-open.org, 2009-01-01)
A number of photovoltaic pilot projects have been started in Botswana since 1990. The first photovoltaic project was Manyana PV project which started in 1992. The Japanese International Cooperation Agency (JICA) PV solar ...
Improvement of marginal materials by fly ash road works
(University of Botswana, 2004)
The national road network continues to play a fundamental and catalytic role in the promotion of social and economic development of Botswana. However, a combination of adverse climatic and geological factors, such as ...

An investigation into the possibility of establishing a building index for Botswana
(University of Botswana, 2001)
Without cost information, project planning is difficult for clients just as pricing of tenders is difficult for construction firms. No agency or organization in Botswana has endeavoured to collect, compile and analyze ...
Environmental impacts of fly ash
(University of Botswana, 2000)
Alarmingly high accumulation of fly ash has led geochemical engineers into finding a solution for the use of flyash as a construction material in the recent past. As of now, although the material has been used in a limited ...
