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...

Previous studies of the cable television industry have focused on the effects of deregulation and competition on cable service prices. These studies use either the "most popular" tier or the "lowest-priced" tier when comparing prices of different cable systems. However, these tiers often represent a different type of cable service so that previous empirical results based on the assumption that ...

To increase the maximum span of cable-stayed bridges, Uwe Starossek has developed a modified statical system. The basic idea of this new concept is the use of pairs of inclined pylon legs that spread out longitudinally from the foundation base or from the girder level. Spread-pylon cable-stayed bridge has distinct advantage like reduction of sag of cables and oscillation of cable during earthqu...

In this paper, the authors study the kinematic isotropic configuration of spatial cable-driven parallel robots by means of four different methods, namely, (i) symbolic method, (ii) geometric workspace, (iii) numerical workspace and global tension index (GTI), and (iv) numerical approach. The authors apply the mentioned techniques to two types of spatial cable-driven parallel manipulators to obt...

Dental anomalies have been known to occur in humans due to a variety of genetic and environmental factors. Combinations of dental anomalies are known to be associated with specific syndromes. A few cases of multiple dental anomalies have been reported in patients with no generalized abnormalities. This case report describes an unusual occurrence of a combination of dental anomalies in an appare...

Triplophysa daochengensis sp. nov. is described from the Daocheng River, a northern tributary of the Jinsha River in Sichuan Province, China. The new species can be distinguished from its congeners by the following characters: body smooth and scales absent; lateral line complete; caudal peduncle compressed, depth unchanging; head length equal to caudal-peduncle length; lower jaw shovel-shaped; ...

Soil-cutting forces are key indicators of root-tuber harvesters and other soil-engaging tools’ performance. To improve operational efficiency, minimise soil disturbance, reduce fuel consumption, the draught vertical involved in root tuber crop harvesting must be minimised. Two field experiments assessed harvester’s performance at a depth 200 mm, varying frequencies, travel speeds on clay sandy ...

As environments are becoming increasingly harsh, the ability of optical fiber cable to withstand such environments is of the utmost importance to outside plant users. Laboratory accelerated aging environments have long been used as a measure to predict field performance of optical fiber and cables' ability to withstand harsh environments. However, there has been an issue in linking the laborato...

EEG recordings made in combined EEG-fMRI studies are corrupted by gradient artefacts (GAs) resulting from the interaction of the EEG system with the time-varying magnetic field gradients used in MRI. The dominant contribution to the GA arises from interaction with the leads of the EEG cap and the human head, but artefacts are also produced in the cables used to connect the EEG cap to the amplif...
