THE ANSWER TO THE QUESTION--A FORCE FOR DEMOCRACY, HUMAN RIGHTS AND THE RULE OF LAW? IS "YES" ACCORDING TO THE AUTHOR, WHO THEN ARGUES THAT HARARE AND MILLBROOK GO JUST THE RIGHT DISTANCE. HE ELABORATES ON THE HARARE DECLARATION, THE CONTEXT OF WHICH CONTINUES TO CROP UP. THE FOCUS OF THE COMMONWEALTH HAS AS ITS BASIS TO WORK ON MORAL AND ETHICAL PRINCIPLES. HARARE AND MILLBROOK HAVE MADE A START IN SETTING DOWN VALUE STANDARDS AND HAS SET A TREND FOR THE FUTURE.

<p class="AbstractText">Practical ducting layout in process plants needs to satisfy a number of on-site constraints. The search for an optimal flow path around the obstructions is a multi-parameter problem and is computationally prohibitively expensive. In this study, authors proposed a rapid and efficient methodology for the optimal linkage of arbitrarily oriented fluid flow ducts using a single-parameter quadratic/cubic Bézier curves in two/three dimensions to describe the centreline of the curved duct. A smooth interconnecting duct can then be generated by extruding the duct face along the curve. By varying the parameter either along the angular bisector or along the axes of the ducts, a family of Bézier curves is generated. Computational fluid dynamics simulations show that the relationship between pressure drop and the adjustable parameter is a unimodal curve and the optimal connecting duct is the one which has the least pressure drop while satisfying on-site constraints can be used for linking the ducts. The efficacy of the method is demonstrated by applying it to some cases of practical interest.</p><p class="AbstractText"><strong>Defence Science Journal, Vol. 65, No. 4, July 2015, pp. 300-306, DOI: http://dx.doi.org/10.14429/dsj.65.8353</strong></p><p class="AbstractText"> </p>
