Abstract Energy dissipation across the weir and dam structures is a vital economic technical solution for designing downstream morphology of any hydraulic system. Accurately estimating energy over system using traditional empirical formulas tedious challenging. Consequently, employing new precise techniques still in high demand crucial. In this study, authors developed an model residual type-A ...

Mond-Weir type duals for multiobjective variational problems are formulated. Under generalized vector variational type I invexity assumptions on the functions involved, sufficient optimality conditions, weak and strong duality theorems are proved efficient and properly efficient solutions of the primal and dual problems.

Weir and Schluter (Reports, 16 March 2007, p. 1574) used variation in the age distribution of sister species to estimate that recent rates of speciation decline toward the tropics. However, this conclusion may be undermined by taxonomic biases, sampling artifacts, and the sister-species method, all of which tend to underestimate diversification rates at low latitudes.
