Fingerprint segmentation is an important step in fingerprint identification processing. Exact segmentation of fingerprint image is very important for fingerprint singular points and minutiae features extraction. In this paper, we present a fingerprint image segmentation algorithm based on support vector machines (SVM). At first, the image is partitioned(More)
Pavements always play a predominant role in transportation. Health monitoring of pavements is becoming more and more significant, as frequently suffering from cracks, rutting, and slippage renders them prematurely out of service. Effective and reliable sensing elements are thus in high demand to make prognosis on the mechanical properties and occurrence of(More)
Use a pure electric passenger car as a research object, design drive control strategy in three modes for different driving conditions and provide motor target torque. To solve the affect of the change of SOC in actual motor output torque, use a penalty function to instantaneously optimize the target torque. Vehicle controller can get the target torque and(More)
The title compound, C(16)H(12)Br(2)F(2)S(2) [systematic name: 1(2),1(5)-dibromo-5(2),5(5)-difluoro-2,7-dithia-1,5(1,4)-dibenzenaocta-phane], has two approximately parallel benzene rings with a dihedral angle of 1.53 (15)° between them and with a centroid-centroid distance of 3.3066 (18) Å. In the crystal structure, mol-ecules are stacked along the a axis(More)
Power user electric energy data acquire system is a system that collects, processes and monitors the electric energy data and realizes the functions such as the automatic collection of electricity information, anomaly monitoring, electricity consumption analysis and information exchange et al. As an important part of the strong smart grid, power user(More)
OBJECTIVE To provide a simple and reliable method for the diagnosis of ventriculoperitoneal shunt malfunction. METHODS A total of 14 participants were enrolled in this study, consisting of 7 patients with suspected shunt malfunction and 7 control cases with apparent normal drainage. In all cases, 0.1 mL of 5% glucose solution was injected into the(More)
Temperature distribution is a critical indicator of the health condition for Liquefied Petroleum Gas (LPG) storage tanks. In this paper, we present a large-scale wireless temperature monitoring system to evaluate the safety of LPG storage tanks. The system includes wireless sensors networks, high temperature fiber-optic sensors, and monitoring software.(More)
