A cosmic ray tracking telescope has been made for the measurement of cosmic rays from different directions, especially those received from the sun direction. Our observations by the telescope shows a noticeable deficiency in the detected number of cosmic rays entering the telescope when its axis was pointing to the sun compared to that entering the telescope with no sun in its field of view. Th...
Considering the importance of predicting volcano eruption and the large number of volcanic peaks across the world, having enough researches in this field is vital. Based on geodetic researches, surface deformation of the earth in the form of uplift or subsidence in the volcanic region, is an indicator of the magma's movement respectively towards the crater or the exit from the tank around. In...
Interferometric Synthetic Aperture Radar (InSAR) technology provides a useful tool for quantitatively measuring the deformation of the earth, influenced by natural factors (earthquake, subsidence, and landslide) and human factors (construction of structures, drilling, and the overexploitation of underground water aquifers). In this context, time-series analysis of radar images allows the monito...
Vandalism is one of the problems of cities today in urban public spaces. Vandalism tendencies are shaped by intrinsic and personality factors. And how the location of the location affects the likelihood of vandalism. Among the landmarks, land use is one of the factors affecting the occurrence of degradation. The role of land use index has been examined under the criterion of land use compatibil...
