Sca Method Based on Qualitative Simulation
نویسندگان
چکیده
It is an effective method to use qualitative reasoning theory to realize sneak circuit analysis (SCA). The method using qualitative modeling combined with functional simulation to realize sneak circuit analysis. The qualitative models of resistive element, switch, transistor, MOS pipe, digital devices, analog devices, mechanical devices and other types of components were established and the qualitative simulation process was studied. Self-developed QSCA software (qualitative simulation-based sneak circuit analysis) is applied to analyze typical cases and verify the technical correctness. The result shows that this method could provide technical support for the system to find sneak circuit problems at the early design stage and it can also be used in the field of fault modes and effects analysis.

Estimating surface flow paths on a digital elevation model using a triangular facet network
[1] This study attempts to develop a method for the simulation of surface flow paths on a digital elevation model (DEM). The objective is to use a facet-based algorithm to estimate the surface flow paths on a raster DEM. A grid DEM was used to create a triangular facet network (TFN) over which the surface flow paths were determined. Since each facet in the network has a constant slope and aspec...

متن کاملSet Covering-based Approximation Algorithm for Delay Constrained Relay Node Placement in Wireless Sensor Networks
The Delay Constrained Relay Node Placement (DCRNP) problem in Wireless Sensor Networks (WSNs) aims to deploy minimum relay nodes such that for each sensor node there is a path connecting this sensor node to the sink without violating delay constraint. As WSNs are gradually employed in time-critical applications, the importance of the DCRNP problem becomes noticeable. For the NP-hard nature of D...
متن کاملA Self-Constructing Neural Fuzzy Network with Dynamic-Form Symbiotic Evolution
In this paper, we propose a self-constructing neural fuzzy network with dynamicform symbiotic evolution (SCNFN-DSE) for solving various problems. A novel hybrid learning approach, which consists of the self-clustering algorithm (SCA) and the dynamic-form symbiotic evolution (DSE), is proposed for adjusting the parameters of neural fuzzy networks. First, the proposed SCA is used to identify a pa...
متن کاملA self-adaptive neural fuzzy network with group-based symbiotic evolution and its prediction applications
In this paper, we propose a self-adaptive neural fuzzy network with group-based symbiotic evolution (SANFN-GSE) method. A self-adaptive learning algorithm consists of two major components. First, a self-clustering algorithm (SCA) identifies a parsimonious internal structure. An internal structure is said to be parsimonious in the sense that the number of clusters (fuzzy rules) is equal to the t...
