This study, tries to suggest a design method based on displacement using finite difference numerical modeling in reinforcing soil retaining wall with steel strip. In this case, dynamic loading characteristics such as duration, frequency, peak ground acceleration, geometrical characteristics of reinforced soil structure and type of the site are considered to correct the pseudo static method and ...

A key aspect in the design of deployable space structures comprising slender elements such as booms is their deployed bending stiffness. In space, due to zero gravitational loading, a high level stiffness not required support neighbouring structures, but instead desirable resist vibrations generated by attitude control system. The morphing composite cylindrical lattice that under development st...

Vasomotion consists of cyclic arterial diameter variations induced by synchronous contractions and relaxations of smooth muscle cells. However, the arteries do not contract simultaneously on macroscopic distances, and a propagation of the contraction can be observed. In the present study, our aim was to investigate this propagation. We stimulated endothelium-denuded rat mesenteric arterial stri...

High-fidelity flatness defects in cold-rolled strip and sheet, arising from highly localized thickness strain variations, present an ongoing challenge to the metal industry. A primary cause of such defects, based on rolling practice, but for which effects have not been rigorously investigated, is transfer work-roll diameter deviations due roll grinding error. This study addresses high-fidelity ...

In this research the rigid plastic material is applied to steady and nonsteady state strip rolling .Stresses and strains distribution in steady state plane strip rolling under the condition of constant of friction are calculated for work hardening and nonhardening materials .In order to attain a comprehensive understanding of the underlying process details, to check and select semi analytical m...

Since hot-rolled strip laminar cooling (HSLC) process is a large-scale, nonlinear system, a distributed model predictive control (DMPC) framework is proposed for computational reason and enhancing the precision and flexibility of control system. The overall system is divided into several interconnected subsystems and each subsystem is controlled by local model predictive control (MPC). These lo...

For a wide class of integer-valued random walks, we obtain exact expressions for the distribution first excess over level and corresponding renewal function as well trajectory supremum if it is finite. We discuss possibilities obtaining explicit pre-stationary stationary distributions walk with switchings at strip boundaries. The research based on factorization representations double moment gen...
