Guided Ammunition is more and more important because of its high accuracy, but its reliability test can't be carried out with all real ammunition because the cost of one guided ammunition can be up to one million yuan, the combination of simulation and real ammunition is very necessary. In this paper, through analysing guided ammunition structure, puts forward test data transform method based on LM...
Through-silicon via (TSV) technology has been the core of the next generation of 3D integration. Although some TSV reliability issues have been addressed in some literatures, but the sidewall scallop resulted from Bosch etch process has not been thoroughly investigated. In this paper, we focus on the effects of different sidewall scallops on the interfacial stress evolution. An axi-symmetric single...

Through-silicon via (TSV) technology known as the core of the next generation of 3D integration has drawn more and more attention. However, due to its high cost and yield problems, it has not been used widely. Nevertheless, TSV is becoming a main stream interconnect method for CIS (CMOS image sensors) packaging. In order to assess the reliability behavior of typical CMOS image sensor such as delamination...
TSV interposer packaging is one of the most important applications for TSV technology. However, the warpage and residual stress arising from the assembly process of TSV interposer have important influence on the reliability of the package. In this paper, two assembly processes were simulated by using the Finite Element Method, the evolution of the stresses and warpage during assembly were compared...
With the development of the economy and people's life, the ice and snow tourism has been developing rapidly, and the development of ice and snow tourism industry has attracted more and more attention. Thus, the evaluation of ice and snow tourism resource value becomes an important issue in ice and snow tourism research. This paper, from economic, ecological and cultural aspects, designs an ice and...
According to the dynamic characteristics of dispatch system of regional support resources, The article introduces the method of simulation-based optimization. It first analyzes the composition of dispatch system of regional support resources, optimizes the support resources dispatch flow, and models the simulation model of the support resources dispatch process based on IDEF3. Then, the article presents...
This article deeply analyzes the system reliability model, and presents a method of modeling the reliability of system tasks. Then this article defines the nodes, the basic unit and the basic module of the system reliability model, and proposes a system reliability prediction algorithm and the algorithm process. Based on this, the article analyzes the system architecture and process of System reliability...
Impact of nodes dynamically, randomly, frequently entering and leaving network on unreliable routing connection has been clearly described by a generalized routing reliability evaluating model according to measuring parameters of relative performance by studying on two-hop unit model presented in this paper. A new rate expression of node entering and leaving spindle region has been established by...
