A Structural Approach to Design Reliable Distributed Applications
نویسندگان
چکیده
This paper presents a method to design reliable applications composed of communicating entities. This method is based on the separation of communicating and processing functions to create a software “network” independent of the computational processes. Common functionalities are isolated to reduce the overhead of replication based approach. In contrast to classical techniques only the processing part of entities is replicated. We exhibit a homogeneous communication structure: the RCHAIN. We describe an algorithm to dynamically reconfigurate the R-CHAIN in presence of host failure. This algorithm provides an efficient way to maintain end-to-end communication.

A novel method for detecting structural damage based on data-driven and similarity-based techniques under environmental and operational changes
The applications of time series modeling and statistical similarity methods to structural health monitoring (SHM) provide promising and capable approaches to structural damage detection. The main aim of this article is to propose an efficient univariate similarity method named as Kullback similarity (KS) for identifying the location of damage and estimating the level of damage severity. An impr...

Colliding Bodies Optimization (CBO) is a population-based metaheuristic algorithm that complies physics laws of momentum and energy. Due to the stagnation susceptibility of CBO by premature convergence and falling into local optima, some meritorious methodologies based on Sine Cosine Algorithm and a mutation operator were considered to mitigate the shortcomings mentioned earlier. Sine Cosine Al...
متن کاملA model with policy network approach for entrepreneurship policy making
One policy making issue that needs to be addressed more effectively through an intergovernmental and participatory approach is entrepreneurship policy. Entrepreneurship is an area where interdependencies are very high, and the establishment of collaborative relationships such as networks is vital. Therefore, a network approach in the entrepreneurial policy-making process, which leads to the inv...
متن کاملStructural Laminate Composites for Space Applications
The creation of reliable structural laminate composites for space applications requires precision design and manufacturing using an integrated, concurrent engineering approach. Since the final material characteristics are established at the same time the part or subassembly is fabricated, part design, fabrication development, and material characterization must proceed concurrently. Because comp...
