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...
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...
During the storage and using process, laser gyroscope zero bias will drift due to influence of temperature, vibration and other environmental factors. This paper uses FMMEA method to analyze the reason for the variation of the laser gyros parameters. Using learning mechanisms of BP neural network to train the model with zero bias data and establish a relationship between zero bias value and the time...
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...
An emergency logistics model based on Location-routing Problem (LRP) is proposed in this paper, and a two-phase heuristic algorithm is used to solve the model. It uses the minimization envelopment analysis method to solve the LRP in the emergency supplies center, and then calculates K shorter paths by the application of the nearest neighbor method. Considering the indexes of time, security, economic...
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...
The quantitative evaluation of system-of-systems architecture is a very important content in the research area of system-of-systems. The framework of system-of-systems analysis process and method of system-of-systems architecture description are reviewed. A new approach of system-of-systems architecture evaluation is proposed. The proposed evaluation approach is a bi-level approach. In the higher...
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...
UHF RFID technology provides significant advantages over traditional object-tracking technologies and it is increasingly adopted and deployed in real applications. Tags collision problem is the key problem affecting the reading efficiency in UHF RFID systems. In this paper, it proposed fixed Q algorithm and adaptive Q algorithm to anti-collision. Both analytical and simulation results show that comparing...
With the evolution of mobile commerce's value chain, the status of the content provider is becoming more and more important and increasingly prominent. Based on the realities in the mobile commerce market, the content providers are classified into content producing provider and content aggregating provider. Based on the business model ontology (BMO) the business model of mobile commerce in analyzed...
