Installed radiation pattern and isolation are critical performance indicators for antennas on large platforms. Prediction of these indicators is highly desirable for antenna placement. Conventional simulation methods require a detailed geometric model of the antenna to be mounted which is, in practice, unavailable from antenna's datasheets. This talk will introduce an effective and efficient equivalent...
A WSN tends to be autonomic, an adaptive and distributive algorithm in Wireless Sensor Network is presented based on cellular automata mechanism, which was sourced from the thoughts of automatic breeding in biology. Each node of the Wireless Sensor Network is assumed to be equipped with CA machine, and change its state (active/stand-by) depends on the state of its neighbors. The main objective of...
In-situ analytics has lately been shown to be an effective approach to reduce both I/O and storage costs for scientific analytics. Developing an efficient in-situ implementation, however, involves many challenges, including parallelization, data movement or sharing, and resource allocation. Based on the premise that MapReduce can be an appropriate API for specifying scientific analytics applications,...
This paper proposes the use of the Cox proportional hazard model (Cox PHM), a statistical model, for the analysis of early-failure data associated with power cables. The Cox PHM analyses simultaneously a set of covariates and identifies those which have significant effects on the cable failures. In order to demonstrate the appropriateness of the model, relevant historical failure data related to medium...
Based on the analysis of building energy efficiency features, considering the construction of energy efficiency factors, this paper AHP establish a comprehensive evaluation of building energy efficiency design model based on grey theory. This model mainly combines quantitative analysis, qualitative and quantitative analysis methods to overcome the evaluation's the subjectivity and arbitrariness, and...
Based on the system-of-systems (SoS) engineering theory, the composition and conceptual model of equipment SoS process was analyzed. The modeling methods for SoS process were developed based on U.S. DoDAF1.5 (Department of Defense Architecture Framework). A brief example of ground attack SoS of shipboard aircraft on Nimitz aircraft carrier was given to illustrate the detailed modeling and analysis...
Clusters of GPUs have rapidly emerged as the means for achieving extreme-scale, cost-effective, and powerefficient high performance computing. At the same time, high level APIs like map-reduce are being used for developing several types of high-end and/or data-intensive applications. Map-reduce, originally developed for data processing applications, has been successfully used for many classes of applications...
The dynamic Simulation of coal enterprises is proposed with system dynamics. Having been proved effective, Zaozhuang Coal Mining Group is applied as an example to carry out case study on four behavior patterns simulated. The results demonstrate that this model is available and can be implemented to simulate, predict and analysis the future development of coal enterprise ecosystem with sound suggestions.
This paper explores the meaning and construction of supply chain logistics costs, and analyzes the influence factors of transportation costs, inventory costs, packing costs, logistics information costs and logistics customer service costs in supply chain logistics costs; Finally the paper establishes the model which analyzes supply chain logistics costs by Analytic Hierarchy Process based on the composing...
Multi-span continuous skew girder bridges have complicate mechanical performance under service loadings and need to conduct three-dimension analysis of internal force and deformation. Considering the loading type is simple for construction simulation of girder bridges, the appropriate computing method is deserved to be investigated. In this article, both the grillage model and beam element model are...
The controllable metal oxide surge arrester is a kind of new electrical equipments which can deeply reduce switching overvoltage in UHV/EHV transmission system. Because of its unique structure, the conventional residual voltage test method could not be used to validate the protection effort of the controllable metal oxide surge arrester. It is necessary to find out an appropriate residual voltage...
