| 1 | The FMEDA Based DC Calculation for Railway Safety Computer显示文摘This paper presents a new algorithm to compute the Diagnostic coverage(DC) for railway safety computer using the Failure modes effects and diagnostic analysis(FMEDA) theory. The importance to work out the DC accurately is stressed. A certain type of railway safety computer's output element is taken as an example to show how the DC is worked out using the FMEDA method. The probability of dangerous failures per hour(PFH) of one certain safety computer is obtained considering the DC.The final results show that the DC is 99.6% and the PFH of the safety is 1.165 fit, which means 1.165 dangerous failures may occur during 1 billion hours' working time,running up to the requirement of the Safety integrity level4(SIL4). This paper provides an example to come up with the DC for safety computer, thus making the PFH calculation more accurate and so is the Safety integrity level. | WANG Juhan GAO Ying CAO Yuan TANG Tao ZHOU Mingjun | 2020 | Chinese Journal of Electronics2020，29，2： | 2 |
| 2 | Changes in spatial variations of sap flow in Korean pine trees due to environmental factors and their effects on estimates of stand transpiration显示文摘It is difficult to scale up measurements of the sap flux density(J_S) for the characterization of tree or stand transpiration(E) due to spatial variations in J_S and their temporal changes.To assess spatial variations in the sap flux density of Korean pine(Pinus koraiensis) and their effects on E estimates,we measured the J_S using Granier-type sensors.Within trees,the J_S decreased exponentially with the radial depth,and the J_S of the east aspects were higher than those of the west aspects.Among trees,there was a positive relationship between J_S and the tree diameter at breast height,and this positive relationship became stronger as the transpiration demand increased.The spatial variations that caused large errors in E estimates(i.e.,up to 110.8 % when radial variation was ignored) had varied systematically with environmental factors systematic characteristics in relation to environmental factors.However,changes in these variations did not generate substantial errors in the E estimates.For our study periods,the differences in the daily E(E_D) calculated by ignoring radial,azimuthal and tree-to-tree variations and the measured E_D were fairly constant,especially when the daily vapor pressure deficit(D_D)was higher than 0.6 k Pa.These results imply that the effect of spatial variations changes on sap flow can be a minor source of error compared with spatial variations(radial,azimuthal and tree-to-tree variations) when considering E estimates. | Minkyu MOON Taek-yu KIM Juhan PARK Sungsik CHO Daun RYU Sanguk SUH Hyun Seok KIM | 2016 | Journal of Mountain Science2016，13，6： | 2 |
