Enterprise supply chain management (E-SCM) is a network management system of interconnected businesses and spans all movement and storage of raw materials, work-in-process inventory, and finished goods from point of origin to point of consumption. E-SCM is also a main part of enterprise resources planning (ERP), and is usually designed as a subsystem of ERP. In this paper, a framework of medium and...
Fracture failure is one of the main failure modes of Micro-electromechanical system (MEMS). Based on studying MEMS's fracture failure mechanism, the reliability models for MEMS fracture failure under mechanical stress field, electrostatic field, and alternating electric field are built with mechanical reliability methods. The model building process is shown by an application case. These models supply...
When the nozzle is working, there is large amount of hot gas at the interface of the carbon-carbon(C/C) exit-cone because of the pyrolysis of insulator. The hot gas may cause high pressure which may impact the reliability of the joint structure. So the high temperature and pressure measurement were developed to measure the temperature and pressure at the interface of the C/C exit-cone and the insulator...
The thermal structure characteristic of the Solid Rocket Motor (SRM) nozzle component under thermal and flow field is investigated by finite element method (FEM). The sensitivity of contact parameter of friction coefficient between multi-layer structures on thermo-structure coupled simulation is priority analyzed and the individual test of the friction coefficient between real material of carbon/carbon...
The dynamic stability of structure is attracting more and more attention. How to control the dynamic instability effectively is a new subject; piezoelectric smart structure makes itpsilas possible. The research of dynamic stability involves some subjects, and was developed recent decades. The birth of intelligent structure gives a new way of the active control for the dynamic instability. In smart...
Mathematical analysis reveals that high frequency signal components are the main issues that make MRF algorithm essential. Moreover, the aliasing problem of subsampling algorithm also comes from high frequency signal components. So based on these mathematical investigations, two fast VBSME algorithms are proposed in this paper, namely roberts cross edge detector based subsampling method and motion...
