This is a review of the current state-of-the-art regarding particular approach to extraction (quasistatic) stress–strain relationship metallic sample from an indentation experiment. It based on application relatively high load (kN range) via large spherical indenter (?1 mm radius), followed by measurement indent profile. profile then used as target outcome for inverse finite element method (FEM...

The problem of “time separation” can be stated as follows: Given a system made of several connected components, each one entailing a local delay known with uncertainty, what is the maximum time for traversing the global system? This problem is useful, e.g. in the domain of digital circuits, for determining the global traversal time of a signal from the knowledge of bounds on the component propa...

The inverse problem in the tangent gas approximation is considered. An exact method for designing airfoils is presented. Constraints on the speed distribution are easily implemented. A simple numerical algorithm which is fast and accurate is presented. Comparison of designed airfoils using the tangent gas method with exact Euler results is found to be excellent for subcritical flows.

the inverse problem of identifying an unknown source control param- eter in a semilinear parabolic equation under an integral overdetermina- tion condition is considered. the series pattern solution of the proposed problem is obtained by using the weighted homotopy analysis method (wham). a description of the method for solving the problem and nding the unknown parameter is derived. finally, tw...
