A satisfactory bituminous mix should have aggregate gradation, which will ensure maximum density and minimum voids in the mix to fulfill requirements of bituminous mix design specifications. In India organizations such as Indian Roads Congress and Ministry of Surface Transport (MOST) [1] have laid down specifications regarding the range of percentage passing of different size of aggregate in th...

Various methods have been used to economically design wastewater and stormwater collection systems. In this article, Discrete Differential Dynamic Programming (DDDP) which is a subsection of dynamic programming (DP) was used. For each pipe network, various alternatives such as depth and slope of pipe laying and various diameters could be considered to satisfy hydraulic and engineering constrain...

These Lecture Notes review the formulation and application of optimization techniques based on control theory for aerodynamic shape design in both inviscid and viscous compressible flow. The theory is applied to a system defined by the partial differential equations of the flow, with the boundary shape acting as the control. The Frechet derivative of the cost function is determined via the solu...
