Development of a mathematical model for reactive power transmission costs in electric power systems
(IEEE http://www.saiee.org.za/publications/2008/sept/99-3-4.pdf, 2008)
The paper gives detailed analyses to help determine the increase in production costs due to the transmission
of reactive power. On the basis of that and with due consideration to the cost of VARS compensation equipment, ...
Cyclic stress–strain behavior of conventional grain and ultrafine grain nickel under biaxial straining
(Elsevier http://www.linkinghub.elsevier.com/retrieve/pii/S135964620800064X, 2008)
Results are presented on the effects of biaxial straining on the cyclic stress–strain response of ultrafine grain nickel (grain
size 260 nm) and conventional grain nickel (grain size 50 lm) over a range of effective ...
Information system based implementation of Semester-to-Semester progression at University of Botswana
(http://ijedict.dec.uwi.edu/viewarticle.php?id=555., 2008)
In August 2002, the University of Botswana changed from a yearlong to a semester based academic system. However, the progression regulations were not be fully implemented on the information system mainly due to problems ...
