one of the most important information in urban forestry is acquaintance of urban landscape’s area or proportion. nowadays, in several countries variable methods are used to achieve this aim. since there is not any complete method to study urban forest’s status in iran, it is impossible to exert authentic management for these resources. hence, in this research, sampling methods and ikonos satell...
This paper describes a cloud type radiance record derived from NOAA polar-orbiting weather satellites using cloud properties retrieved from the Advanced Very High Resolution Radiometer (AVHRR) and spectral brightness temperatures (Tb) observed by the High Resolution Infrared Radiation Sounder (HIRS). The authors seek to produce a seamless, global-scale, long-term record of cloud type andTb stat...
Ice cloud detection from AMSU-A, MHS, and HIRS satellite instruments inferred by cloud profiling radar" (2014). NASA Publications. Paper 175. An algorithm for ice cloud detection aided by support vector machine (AID-SVM) is presented. The AID-SVM algorithm is applied and tested for the Advanced Microwave Sounding Unit-A, microwave humidity sounder (MHS), and high resolution infrared radiation s...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
introduction frost as a harmful climatologic phenomenon affects various human activities and biological processes. due to mountainous nature of kurdistan province as the study area of this research in one hand and type and diversity of effective air masses on the other, the frequency, severity and duration of this phenomenon in the province are outstanding. confronting frost could be one of the...
Given the importance of snow, it seems necessary to predict its resultant runoff for optimized usage. In addition, due to snowbound regions cloudiness in winter season, the notice of snow cover area (SCA) using satellite images is difficult. Hence, to help better water resources managing in mountainous areas using supplementary methods for simulating the SCA is necessary. As a case study, Horo-...
Various classification methods have been applied for low resolution of the entire Earth's surface from recorded satellite images, but insufficient study has determined which method, for which satellite data, is economically viable for tropical forest land use mapping. This study employed Iterative Self Organizing Data Analysis Techniques (ISODATA) and K-Means classification techniques to classi...
The objective of this study was to assess the relationship betweenvegetation, landform and physicochemical properties of soil. At the first terrainmap unit were provided using the landsat thematic mapper (TM) satellite images,aerial photograph, topographical and geology map. Field sampling was done in therepresentative area using plot sampling. 104 plots 100 m2 were sampled in eachplot landform...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
