The increasing amount of computation in heterogeneous architectures (including CPU and GPU cores) puts a big burden on memory subsystem. With the gap between compute units and the memory performance getting wider, designing a platform with a responsive memory system becomes more challenging. This issue is exacerbated when memory systems have to satisfy a high volume of traffic generated from heterogeneous...
To overcomes the disadvantages of computing the attributes' weight method in multi-attribute decision problem. In this paper, a weighted averaging method based on Dempster-shafer evidential theory and grey fixed weight cluster has been used. Firstly, by using the Dempster-shafer evidential theory can integrate the subjective and objective weights to get the weight coefficients, and then avoid the...
In Physics of Failure (PoF) based Single-board computer reliability prediction, FMMEA is firstly introduced to get the failure modes, mechanism and physics of failure models. Performance parameters such as material, structure, technology and stress are used to found the simulation model. Some data are acquired by stress analysis and then Probabilistic Physics of Failure (PPoF) models are used to carry...
Failure Mode, Mechanism and Effect Analysis (FMMEA) is a reliability analysis method which is used to study possible failure modes, failure mechanisms of each component, and to identify the effects of various failure modes on the components and functions. This paper introduces how to implement FMMEA on the Single Board Computer in detail, including system definition, identification of potential failure...
A system optimization framework based on design of experiment (DOE) and simulation is proposed. Simulation is effective in the optimization of many complex systems, however, it is time consuming and tough. DOE can reduce the number of test cases drastically while ensuring input combination is of wise coverage of design space. A framework incorporating simulation and DOE is proposed, which provides...
Based on the Model-Driven Testing (MDT), this paper proposed a model-driven conformance testing method for 3G network management north bound interface in order to minimize the impact from specifications changes and technological innovations. The core thought of the method is to derive interface technology independent test model (PIT) from platform independent model (PIM) defined in analysis specifications...
Establishing a reasonable connecting preference is one of the most important opinions to give priority to the development of urban public transport now. From the view of equilibrium among the three commuter traffic modes(bus transfer metro, bus transfer bus and auto), the generalized travel utility was introduced into the logit model, the model parameters were calibrated through traffic data survey,...
In a three-dimensional (3-D) model-based objects tracking and recognition system, the key problem of objects location is to establish the relationship between 2-D objects image and 3-D model. Based on 3-D model projection and 2-D image feature extraction, a modified Hausdorff distance is used to establish the matching function. The relationship between matching parameters are described with a probability...
Service Oriented Architecture (SOA) and Service Oriented Computing (SOC) are prevailing technologies for sharing and reusing resources. Service composition is an envisioned methodology used in SOA and SOC to build value-added services. The existed service clustering and selection models are mostly designed for service discovery and there is few considering the requirement of service composition from...
