With the continuous expansion of the power system, security and stability of the power distribution network is particularly important. As the power distribution equipment's main insulation, heat-shrinkable material has caused great concern of the department of operation and maintenance. Based on plenty of experimental results of the heat-shrinkable material with different operating time, the elongation...
End-systolic volume (ESV) and end-diastolic volume (EDV) are key parameters in the analysis of left ventricular (LV) function, and the study of cardiac remodeling. The volume regulation graph (VRG) relates these fundamental determinants, and permits convenient stratification for clinically relevant covariates. This contribution analyzes sex-associated differences in hemodynamic parameters for 197...
In the exploration and evaluation of the metalliferous veins, traditional geophysical inversion method can only get the indirect parameters of the target property, but cannot accurately reflect the geological parameters of ore veins media attributes. In order to get the intrinsic geological parameters and internal distribution of the metalliferous veins by means of inversion, in this paper, we construct...
In this paper we adopt the similarity principle to study GPR response to voids under road surface or in the levees and dams by cross-examination of GPR data acquired using both high-frequency antennas on laboratory bench-size models and low-frequency antennas in the field. In physical world the similarity principle is widely used in theoretical study and engineering practice. In short, by the similarity...
Lunar penetrating radar (LPR) is an important way to carry out lunar probing. The detection result of Rabbit lunar radar carried by Chang'E 3 provides a reliable scientific foundation for studying the underground structure and depth distribution of the moon. The regolith modeling and numerical simulation can provide a reliable reference for lunar detection and data interpretation. In this abstract,...
Lunar Penetrating Radar (LPR), equipped on the rover of Chang'E-3 mission (CE-3), estimates the thickness of lunar shallow structure and detects three layers structure. In order to analyze the data of LPR and build an interpretation and experimental model, in this paper, we carry out LPR simulation and processing algorithm to provide some reference for future LPR detection. Firstly, we build the stochastic...
New designs of bend-insensitive multimode fibers are proposed. The bending loss can be reduced by a factor of 10 while meeting all other standard requirements. The design concept is validated by actual fiber results.
This paper reviews a technology for making nano-engineered optical fibers. Key features and advantages of nano-enginneered glass fibers are discussed. Fiber designs and their applications are presented.
Singular point detection is an important issue in fingerprint image analysis. General methods like Poincare index method can detect singular points in non-arch type fingerprints but fail on arch-type fingerprints. Some more sophisticated methods like complex filter method also face the same problem. In this paper, we propose a systematic method for detecting singular points in fingerprint images which...
A new classification logic for land cover at regional scale is proposed. The critical features of this classification are that: it is based on spectrum (color) and primary attributes of plant-canopy structure, that are important to globe change modeling and can be measured in the field for validation or/and by remote sensing; according to the phonological difference among broadly defined vegetation,...
