For domains Ω with piecewise smooth boundaries the generalized solution u ∈ W 2 2 (Ω) of the equation ∆xu = f with the boundary conditions u = ∆xu = 0 in general cannot be obtained by solving iteratively a system of two Poisson equations under homogeneous Dirichlet conditions. Such a system is obtained by setting v = −∆u. In the two-dimensional case this fact is known as the Sapongyan paradox i...

increasing competition in the air transport market has intensified active airlines’ efforts to keep their market share by attaching due importance to cost management aimed at reduced final prices. crew costs are second only to fuel costs on the cost list of airline companies. so, this paper attempts to investigate the cockpit crew pairing problem. the set partitioning problem has been used for ...

This work presents a case study for a portion of a business process improvement systematic innovation analysis completed at Presbyterian Health Services of New Mexico. Manifold techniques and methodologies are demonstrated which could be useful to anyone pursuing innovation work. The reader will be given insight to: what aspects of an innovation analysis correlate with what portions of the prob...

The paper presents the semi-numerical solution for the magnetohydrodynamic (MHD) viscous flow due to a stretching sheet caused by boundary layer of an incompressible viscous flow. The governing partial differential equations of momentum equations are reduced into a nonlinear ordinary differential equation (NODE) by using a classical similarity transformation along with appropriate boundary cond...
