Logic Expression and Structure Simplification for SFEP of Sensor System

IEEE Sensors Journal (2020)

Cui Tiejun Shasha Li

The system consisting of numerous sensors can be abstracted as a network structure with topological properties. Therefore, the safety and reliability of sensor system can be studied based on the abstract topology. In the topology, the nodes represent the sensor and the lines represent the signals transmitted by these sensors. Aiming at the abstract topology structure of sensor system, the author proposes to use the system fault evolution process (SFEP) to describe the fault evolution process of sensor system, and uses the Space Fault Network (SFN) to describe and analysis. To make the SFN describe the SFEP with the uncertainty, diversity and evolution characteristics, the paper puts forward the SFEP logical expression and SFN structure simplification method. The safety of sensor system is studied on the system topology. Firstly, it introduces the research background and the basic theories involved. Using flexible logic (FL), ternary logic (TL), factor space (FS) and other theories, we have realized FL description of SFN, TL system and ternary division of SFEP, and structure simplification of SFN in SFN framework. SFN has the ability to describe the uncertainty, diversity and network structure of SFEP. It provides a theoretical basis for the intelligent research of SFEP, and also realizes the intelligent analysis of SFN. The proposed method can be used to represent and analyze the fault process of sensor system.

Error Analysis of Scanning Digitizing for Chart Spatial Data

Hydrographic Surveying and Charting (2010)

Cui Tiejun

This paper firstly introduces the concept of chart spatial data and scanning digitizing,then analyses and compares the error resource of scanning digitizing for chart spatial data,in the end during the testing of scanning digitizing to one chart,scanning digitizing error for obvious man-made surface features is inspected by mean value.The conclusion of the testing is scanning digitizing error may not obey the normal distribution,but more system features are put up.It has a definite significance for farther analyzing error distribution of scanning digitizing for chart spatial data.

Based on the dimensionless three indexes system to assess open stope performance

Meitan xuebao (2014)

Cui Tiejun

The presentassess open stope performance measures to get result was based on the dimension,the measures can not compare different scale stope performance and fail to adequately capture certain geometrical aspects of overbreak or under-break. The paper constructed a set of three indexes assess system with dimensionless. Based on the system,the characteristics of some typical shape were analyzed. The system is of three indexes including circularity( C),extensivity( E),hemisphericity( H),C measures for describing the regularity of shape of over-break and under-break,E measures for describing the dispersity and spreadability of shape of over-break and under-break,H measures for describing the equivalent depth of volume of over-break and under-break. The four dimensionless indexes were determined and given its value ranges,its numerical division according to semantic. The evaluation index system have unified evaluation method,evaluation index and evaluation standard,and then the comparison of the different stope performance was realized. The evaluation of four hypothetic stope obtain the value of the three indexes and their semantic,and then determine their potential failure mode.

Numerical Simulation on the Stress and Strain of Lining Structure with Double Shield Tunneling Construction

Advanced materials research (2012)

Feng Wang Cui Tiejun

This paper takes the Section 201 of shield construction engineering in Dalian Metro Line 2 as an example to analyze the deformation law of surrounding soil and the tunnel lining structure stress during shield tunnel construction. The shield tunnel construction is simulated dynamically by ADINA and the shield tunnel structure model of the concrete lining is established. This model is a three-dimension nonlinear finite element calculation model concerned with the grouting soil and original state soil. Taking the soil lithology in the upper layer and interact influences, we analyzed the dynamic process of shield construction, soil grouting and lining supporting and the stress distribution in difference reinforced concrete supporting segments and the ground settlement characteristics. Through numerical analysis method to study the deformation law of soil surrounding tunnel and the stress in tunnel lining, we get the results to compare with the results of Peck formula under the same condition. After generating the conclusions, we can provide several suggestions for shield tunneling construction, lining segment design and control of the ground surface settlement during the construction.
