Determination of Refractivity Gradient and Modified Refractivity Gradient for Cross River State

technical and legal parameters for determination of river boundary,( case study haraz river)

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...

1 A method for determination of Gaseous Refractivity based onthe

We present a speciic method and its software implementation to determine the refractive index (n) of various gases, analysing the interferometric data of a pressure tunable Fabry-Perot interferometer from visible to VUV region. The principal idea of this method is to apply the Discrete Fourier Transform (DFT) on the data of the light intensity as a function of the gas pressure, in order to dete...

Determining the Refractivity

High accuracy of impact height is important to get reliable Radio Occultation (RO) measurements of the atmosphere refractivity. We have made an investigation on how accurately we can measure the impact height at ground level using wave optics simulations, realistic refractivity profiles, a realistic simulator for an advanced RO instrument including noise, and using phase matching for the invers...

The Refractivity of Air

The air density equation of Jones, Edlen's dispersion formula for standard air, and Edlen's empiricallyderived expressions for the effects of CO 2 abundance and water vapor partial pressure on refractivity have been combined into a simplified equation for the refractivity of air, and estimates have been made of uncertainties in calculated refractivity. Under ambient conditions typical of metrol...
