Cable System Management requires an assessment of the health of the cable systems. It is increasingly common for the assessment of aged cable systems to be made through the application of diagnostics measurements. Papers and standards have established benchmarks for diagnostic measurements that help utility engineers to reach a condition assessment. Generally, extremes of healthy and non-health...

Structures consisting of cables and membranes have been of interest to engineers due to their higher ratio of strength to weight and lower cost compared to other structures. One of the challenges in such structures is presence of holes in membranes, which leads to non-uniform stress and strain distributions, even under uniform far-field deformations. One of the approaches suggested for controll...

In order to detect distributed ground surface deformation, an elastic helical structure Time Domain Reflectometry (TDR) sensing cable is shown in this paper. This special sensing cable consists of three parts: a silicone rubber rope in the center; a couple of parallel wires coiling around the rope; a silicone rubber pipe covering the sensing cable. By analyzing the relationship between the impe...

Due to the influence of peculiar material characteristics, austenitic stainless steel bolts are always easy be locked during disassembly. This is not only seriously affected service performance bolts, but also affects reuse bolts. In this paper, main causes and mechanism locking blots in process fastening summarized, effective measures containing correct selection, carefully clean before assemb...

Time domain reflectometry (TDR) technology is an ideal cable length measurement method. The traveling wave propagation velocity is the key to the measuring accuracy of the TDR cable length measurement system. The cable crimp levels effect on traveling wave propagation velocity is analyzed theoretically, and the corresponding experiment is done. The experimental results are match to the theoreti...

Bolted connections are essential components that require regular inspection to ensure bridge safety. Existing methods mainly rely on traditional artificial vision-based inspection, which is inefficient due the many bolts of bridges. A method using deep learning and unmanned aerial vision proposed automatically analyze bolts’ condition. The contributions as follows: (1) Addressing problems motio...

OBJECTIVES: This course aims to describe the effects of colored noise in the parallel MRI [1– 3] experiment and how to perform a reconstruction, which takes the noise distribution into consideration. Techniques for SNR scaled reconstruction [4] are described for Cartesian and non-Cartesian imaging. The course will also describe iterative reconstruction algorithms and their regularized forms. So...

In nature we can see and hear the ocean waves as they swell, crest, and crash, rushing forward and then receding backward. An experienced surfer rides the waves and gracefully balances while rising with the swell and crest, and then just as gracefully lands with the wave’s denouement. Similarly, we can see and hear trees as they sway back and forth with the wind, and we can feel the wind blowin...

This paper presents a reconfigurable cable parallel robot, which spatial topology can be reconfigured through managing the branch numbers and the hoisting points of the end-effector. An experimental prototype of the reconfigurable cable parallel robot is designed and developed. A typical configuration of the reconfigurable cable parallel robot is analyzed as a case study. The finite element ana...

F or a shielded cable, an approximate relationship valid from few kHz up to the first cable resonance can be derived from its Transfer Impedance (Zt ) allowing to predict the cable shielding factor. This Cable Shielding factor, as a figure of merit, is often preferred by engineers dealing with product specifications and early design. Being not necessarily EMC specialists, they can relate it dir...
