We propose a method for visualizing a set of related metabolic pathways using 2 2D graph drawing. Interdependent, twodimensional layouts of each pathway are stacked on top of each other so that biologists get a full picture of subtle and significant differences among the pathways. Layouts are determined by a global layout of the union of all pathway-representing graphs using a variant of the pr...

A rigorous semi-analytical approach for specific microstructured optical fibers, which are formed by layered cylindrical arrays of circular rods symmetrically distributed on each of concentric circular rings, is presented for both of scalar-wave formulation and full-wave formulation. The method uses the T-matrix of a single circular rod, the reflection and transmission matrices for a cylindrica...

A one-dimensional impact problem is employed for a layered system that comprises heterogeneous materials with different geometrical configurations. The system mimics transmitter for Multiple Integrated Laser Engagement Systems (MILES). The analytical model tracks the stress wave propagation through this layered structure as a result of the mechanical shock from blank rounds as they fired. The r...

In this study, a limit equilibrium method has been developed that satisfies all conditions of equilibrium and assumes circular slip surfaces. All force and moment equilibrium equations are employed without using simplification assumptions. A non-linear optimization technique is used to solve the system of equations with the corresponding constraints. The proposed method is capable to determine ...

Tube hydroforming is one type of unconventional metal forming process in which high fluid pressure and axial feed are used to deform a tube blank in the desired shape. Bi-layered tube hydroforming is suitable to produce bi-layered joints which can be used in special applications such as aerospace, oil production, and nuclear power plants. In this work a finite element study was performed using ...
