Determination of the displacement rate of the Masouleh landslide for management of landslide risk by Radar Interferometry
One of the most common natural phenomena occurring in mountainous regions of the world is landslide which causes critical damages and is considered as a natural disaster. Iran is a country which annually suffers from this disaster and its consequent damage of about 500 billion Rial. Over the last 15 years, an increasing number of researches have aimed to demonstrate the applicability of the im...
متن کاملDetermination of Mercury by Radiochemical Displacement Methods
1-(2-Pyridylazo-2-naphthol), PAN, has been introduced and extensively employed as a reagent in radioanalytical chemistry in our laboratories. An earlier communication dealt with the determination of micro amounts of Cu(II) by displacement of labelled zinc from Zn-PAN complexl'. The present work is intended to develop a similar method employing Zn-PAN complex for the determination of mercury(II)...
متن کاملAnalysis of Large-scale Displacement Using Radar Interferometry Technology in Open-pit Mines (Case Study: Gol Gohar Sirjan Mine)
Abstract Mines with their displacements cause damage to infrastructure and land, so it is important to control the displacement caused by mines. Also, the amount of minerals extracted from mines has always been of interest to managers. On the other hand, radar interferometry, given the production of repetitive and full images and the acceptable accuracy of this method, in examining be sugge...
متن کاملPrecision displacement measurement by active laser heterodyne interferometry.
We demonstrate an active laser heterodyne interferometer which can automatically compensate environmental disturbances and is capable of precision displacement measurement. Two Zeeman He-Ne lasers were employed. Laser II was used as the light source to stabilize the interferometer by using a piezomirror in a feedback loop. The hetereodyne signal of the two lasers was used to directly calibrate ...
متن کاملRelativistic corrections in displacement measuring interferometry
Displacement measuring interferometry is based on measuring the Doppler frequency shift that a beam of radiation undergoes upon reflection off a mirror connected to a moving stage. Usually the velocity of the reflecting stage is very small compared to the speed of light and is therefore deduced using the classical expression for the Doppler shift. We calculate relativistic corrections to the Do...
