This article is aimed at modeling of transmission line inspection robot in order to improve the mechanical mechanism and achieving dynamical stability to navigate through overhead electrical transmission lines while passing obstacles. A new mechanical mechanism design is developed that allows robot navigate more stable than current commercial inspection systems. The behavior of investigation ma...

One of the recently considered applications of fiber optic, in their usage in building lighting systems. In this research, in order to reduce energy consumption, by transmission of sun light from the roof to the desired place (i.e. an office), the required standard luminance is produced. The main aims of this research are :1. Reduction of energy consumption.2. Making the place compatible with t...

Twelve types of phototherapy eyeshields showed peak light transmission of less than 0.1%, and none transmitted greater than 0.04% light in the 460 nm spectral region. Commercial eyeshields offered no advantage over locally made ones. The choice of shield may be less important than how it is secured over the infant's eyes.

Recently atomic magnetometers are one of the best tools in biomagnetic measurement such as magnetic field of brain and heart. In this paper, the technology of optically pumped atomic magnetometer based on circularly polarized light absorption pumping is described. We have been investigated a new method for measuring polarization effect in an alkali vapor based on polarized light transmission. I...
