The system architecting process is the hierarchical reduction of ambiguity associated with user needs and system design. Design allocation, and subsequent integration, implicitly requires a mechanism by which levels of detail can be added and removed from a decision scenario. This paper addresses the idea of engineering model sharing through the concept of vertical and horizontal extensibility as...
With the widespread use of WEBGIS system, we design the architecture of diseases and Insect Pest Information System (DIPS) based on WEBGIS. First, expound the structure principle and maintenance methods of the component model management subsystem, propose common interface standards and design interface component model that suitable for WEBGIS system. Then, present design ideas and realization method...
According to the heterogeneous characteristics of wireless mesh networks and the QoS requirements of multimedia applications, we design a novel QoS adaptive architecture for WMNs that is cross-domain, cross-layer and cross-node. Furthermore, this architecture is mathematically described by using a bi-level programming model. This model uses the optimization results of subnets as the optimization parameters...
MDA is a current trend that shifts the focus and effort from implementation during the development process to models, metamodels and transformations. The four-layer MDA architecture still suffers from the lack of formalization of its artifacts and processes leading to ambiguity and low reliability problems. For instance, currently there is no way for ensuring that MDA transformations are semantic-preserving...
Ever increasing component counts of a system-on-chip makes communication among components complex and diverse. Thus communication architecture becomes a major performance determining candidate. This paper proposes a formal technique for system level performance analysis that can help the designer to select the appropriate arbitration scheme for a chosen bus-based communication architecture. For a...
Our intention here was to highlight a replacement of adaptation algorithm in MRAS by the help of alternative artificial neural network (ANN) which has received great attention in recent years. The main objective was to find and design some alternative neural network within the electric drive control. After a short discussion of hardware components, an overview of radial basis function (RBF) neural...
The most fundamental ingredients of computer simulations are the analytical or experimental models and their visual representations (views). This paper presents AVRA, a framework that receives the simulation models and the description of the view as XML files and dynamically generates a VR (Virtual Reality) application that corresponds to those specifications. The result consists of a 3D scene with...
With the development of missile weapons in the high-tech local wars, higher performance, shorter lifecycle, and lower cost have become the new requirements for missile design. Consequently, an advanced integrated missile design environment is an instant need to provide the technical support. This paper explores some key technologies of this integrated design environment, including architecture, design...
This paper introduce a type-2 fuzzy function system for uncertainty modeling using evolutionary algorithms (ET2FF). The type-1 fuzzy inference systems (FISs) with fuzzy functions, which do not entail if...then rule bases, have demonstrated better performance compared to traditional FIS. Nonetheless, the performance of these approaches is usually affected by their uncertain parameters. The proposed...
