Such components should be deployed into embedded, pervasive environments, and several deployment architectures are typically possible. These deployment architectures can have significant impacts on system reliability. However, existing reliability estimation approaches are typically limited to certain classes or exclusively concentrate on software reliability, neglecting the influence of hardware resources, software deployment and architectural styles. The selection of an appropriate architectural style has a significant impact on system reliability of the target system. Therefore, we propose a novel software architecture （SA） based reliability estimation model incorporating software deployment and architectural style. On the basis of two architectural styles, we design influence factors and present a new approach to calculate system reliability. Experimental results show that influence factors provide an accurate and simple method of reflecting architectural styles and software deployment on system reliability. It is important for considering the influence of other architectural styles on system reliability in large scale deployment environment.展开更多

The diversifi ed styles and types of these buildings refl ect the historical changes of modern Chinese buildings, and also record history of that age. The buildings are intangible cultural heritages of not only Nanjing, but also China. Study on and protection of these buildings is a process of reviewing modern architectural history of China, and also rethinking the inheritance and development of traditional Chinese cultures. In addition, the research promotes the coordinated development of modern urban construction and social cultures.展开更多

The Rapid development of Christian buildings started from 1840 due to the entry of foreign missionaries. Various types of Christian buildings rose up in the province, were constructed by local builder, but designed and funded by foreign missionaries. In comparison to other Christian buildings, churches have unique historical value, cultural value and also special meaning in architecture art. However, their cultural heritage value has not yet been sufficiently considered. They are facing the prospect of being damaged and demolished, even in nowadays. It is incumbent that their architecture to be historically evaluated and that ways to be found to preserve them. In this paper, the author will focus on the neoteric Christian churches and illustrate the architecture by taking examples from the churches in Shaanxi, along with the intention to clarify the relationship between social background and the history of evolution of these churches. In addition, the authors have taken the chance to understand more comprehensively about the fascinating history of these Christian churches by way of field surveys and taping into archival documents.展开更多

An appropriate architecture for a system is a key element of its success. Based on the practice of Jadebird software production line, this paper proposes a software architectural style based on hierarchical message buses, named JB/HMB. In this style, the component model consists of external interfaces, static structure and dynamic behavior, which depicts a component from different aspects. Supported by message buses, components interact with one another by messages, which can be used to describe distributed and concurrent systems well. JB/HMB style supports stepwise decomposition and refinement, and runtime system evolution. Finally, characteristics of JB/HMB style are summarized as a conclusion, and future research directions are specified.展开更多
