This paper introduces the surface inspection system for wire rod in steel-making industry. The inspection system is based on vision technology. We have developed illumination system with blue LED lighting sources to get best quality of surface image. And we have implemented defect detection algorithms based on block sigma transform which can recognize wire rod objects and segments defect candid...

Dynamic capacity increase in high voltage electric power transmission line is currently the most economical method for solving electric power transmission bottleneck nowadays. DS18B20 temperature sensor is applied to the dynamic capacity increase of high voltage transmission lines to measure the conductor temperature and ambient temperature. The paper is focused on the experiment of DS18B20 bot...

The width of an interconnect line a ects the total power consumed by a circuit A tradeo exists however between the dynamic power and the short circuit power in determin ing the width of inductive interconnect The optimum line width that minimizes the total transient power dissipation is determined in this paper A closed form solution for the op timum width with an error of less than is presente...

Electrocution is not an uncommon cause of death. A case of fatal electrocution by a metal wire that was used as a support for the insulated television cable wire is reported. Electric current flowed through the metal wire when it touched the residential power line. Electrical injury caused because of contact with the live metal wire is described with histopathological findings. This case report...

A fundamental process of surface energy minimization is the decay of a wire into separate droplets initiated by the Rayleigh-Plateau instability. Here we study the linear stability of a wire deposited on a unidirectionally patterned substrate with the wire being aligned with the pattern. We show that the wire is stable when a criterion that involves its width and the local geometry of the subst...

The Accelerator Test Facility (ATF) at KEK offers a very low emittance micrometre sized beam of 1.28 GeV electrons close from the conditions expected at the International Linear Collider (ILC). The ATF should soon be able to provide a bunch spacing similar to that of the ILC. This accelerator being a test facility it is possible to have dedicated machine time with custom beam optics for our tes...

A survey of frequency domain models to describe cables of the access network of operators is presented. The cable characteristics of some commercial cables are measured and the parameters of the used models identified. From this, the properties and application areas of physical models as well as rational functions are discussed. It will be demonstrated and explained why some frequently used cab...

A novel servomotor design that is powered and controlled through only one wire is presented in this paper. A traditional servomotor needs both a power cable and a control cable connecting the motor to a control amplifier. Cables are bulky, heavy, and expensive and, more importantly, difficult to install and maintain in many applications. Particularly for multi-axis applications, like robots and...
