In this paper, the generation and control turbulence in a wind tunnel, for design, analysis and testing of wind turbines is proposed. The designed wind turbines will be focused for domestic use. Modifications to the wind tunnel are made in order to generate the turbulences in the test chamber. Specifically, for the turbulence analysis, the reflective symmetry concept is used to group the different...
Enterprise Modeling is the key of information system development, because it is a decision support tools methods of collection of enterprise information. This paper produced a new modeling method that integrated IDEF and UML, established some models with one instance, analyzed the modeling steps. The method can help the modeling engineers in various fields build and test the specialized models of...
Congestion problem in the airport declines the passengers' satisfaction. The passengers' satisfaction is an important matter to the sustainability operation of the airport. Airport management has to develop a company program to improve the quality of service to the passengers. To regulate the passengers' processes, it is important to define the performance of existing system. The objective of this...
This paper focuses on the challenges of modeling cyber–physical systems (CPSs) that arise from the intrinsic heterogeneity, concurrency, and sensitivity to timing of such systems. It uses a portion of an aircraft vehicle management system (VMS), specifically the fuel management subsystem, to illustrate the challenges, and then discusses technologies that at least partially address the challenges....
The Federal Aviation Agency (FAA) is facing the challenge of significant increases in workload for the air traffic control system. The Next Generation Air Transportation System (NextGen) efforts are aimed at providing the changes to the system needed to meet that challenge. In order to be prepared, the FAA is looking at the competencies needed to develop and deploy the improvements in an effective...
Feature dependency Modeling describes model of mutual constraints among features. It is essential activities for development of software product line. This paper introduces local dependency and global dependency of feature. With analyzing relationship of feature dependency, we propose an approach of feature dependency modeling. It not only provides specification of local dependency such as decomposition...
This paper describes a generic method to assist architectural design of heterogeneous systems. Improvement lie on better design rationalization and lesson learn acquisition. We use the model driven approach to define architectural models of the system. The approach is based on the translation of requirements in quantitative and measurable technical indicators that could be integrated to the design...
