Based on the literature and in-depth interview, this paper proposes a model for indentifying the consumer motivations participating in virtual brand community. They are comprised searching for effective information, obtaining preferential treatment, seeking offline interaction, sharing post-purchase experience, and maintaining information quality. Moreover, their effects on consumer participation...
In this paper, the failure number of hydroelectric power equipments in the whole life is predicted based on Crow-AMSAA Reliability Growth model. Considering influence of preventive maintenance to failure rate, service age reduction factor E is introduced to adjust service year of equipment and the maintenance cost model of hydroelectric equipments in the life cycle is derived. The optimal preventive...
Godson-3 is the latest generation of Godson microprocessor family. It takes a scalable multi-core architecture with hardware support for accelerating applications including X86 emulation and signal processing. This paper introduces the system architecture of Godson-3 from various aspects including system scalability, organization of memory hierarchy, network-on-chip, inter-chip connection and I/O...
Through 335 questionnaires collected from 22 corporations in our survey, the two key factors which can influence the employee's knowledge reception readiness in the process of knowledge transfer, namely the degree of knowledge customization and the reliability of the knowledge source, are studied empirically. Moreover, the mediate effect of the employees' involvement degree and specialization degree...
The method of failure modes, effect and criticality analysis (FMECA) is one of absolutely necessarily elements in reliability systems engineering. The effective application of FMECA can improve the freight car quality and reliability. The basic principle of FMECA is introduced. The method to apply FMECA into bogie failure of railway freight car is proposed. The quantitative and qualitative evaluation...
In traditional dynamical fault tree analysis, it is necessary to modularize DFT tree firstly so as to obtain static subtrees and dynamic subtrees. Generally, binary decision diagram (BDD) and Markov chains are utilized in the DFT to process static and dynamic subtrees, respectively. However, due to the possibility of state combinatorial explosion problem in Markov chain, it is difficult to analyze...
As the most attractive realization of component-based software, composite Web service asks a heavy demand for reliability prediction in the early stage for service discovery and service composition. Although it is believed that input should be one of the most important aspects affecting the reliability of a component-based system, research of both giving more details on an operational profile and...
Along with the development of object-oriented technology, component development is gradually extended to commercial off-the-shelf (COTS) components and component-based software development (CBSD) has gradually become the dominant orientation of the field of software engineering. The claims of high reliability need further investigation based on reliability analysis techniques that are applicable to...
The purpose of this paper is to study effect of thermal cycle condition on the reliability of lead-free flip chip solder joint. Flip chip assembly was subjected to thermal cycle (MIT-STD-883) condition. Two dimensional finite element analysis (FEA) has been carried out using ANSYS commercial software. There are two types of lead-free solder (Sn96.5-Ag3.5 and Sn95.5-Ag3.8-Cu0.7). They used flip chip...
