High-voltage transmission lines are the main facilities for power transmission, and they mainly composed of aluminum conductor steel-reinforced (ACSR). Over long-term outdoor use, overhead will encounter lightning strikes, chemical pollutant corrosion, deicing, wind vibration, other external forces. This often results in a series potential failures, such as breakage, strands. In order to ensure...

A computer-aided system for transformation of mathematical figures into tactile graphics is useful for visually impaired students when they learn mathematics and science. To develop such a system, research on mathematical figure recognition techniques is needed. There are so many mathematical figures in which graphs are drawn using broken lines. Under this situation, this paper discusses a meth...

We propose an automatic line tracking method which can deal with broken or closely-spaced line segments more accurately than previous methods over an image sequence. The method uses both grey scale information of the original images and geometric attributes of line segments. By using our hierarchical optical ow technique, we can get a good prediction of line segments in a consecutive frame even...

The determination of the particle momentum in HEP tracking chambers requires a fit of a parametrization to the measured points. Various effects can result in deviations to the ideal helix curve in the magnetic field of a solenoid, and the fit with a pure helix parametrization is not optimal. One effect is multiple scattering, which causes a “random walk” of the particle and affects especially l...

It gives me great pleasure to deliver the keynote address at the Asian Bond Conference organised jointly by the Thai Bond Dealing Centre (Thai BDC), Fixed Income Money Market Dealers Association of India (FIMMDA) and Primary Dealers Association of India (PDAI). It is a matter of significance that some of the major self-regulatory organisations (SROs) in the debt markets of Asia have taken this ...

In this paper we present a novel model based approach to detect severely broken parallel lines in noisy textual documents. It is important to detect and remove these lines so the text can be segmented and recognized. We use Directional Single-Connected Chain, a vectorization based algorithm, to extract the line segments. We then instantiate a parallel line model with three parameters: the skew ...
