To investigate land use changes, Qale Shahrokh basin (15098.1 ha area) was selected. Satellite images of Landsat sensors (MSS, TM and ETM+) were used. After improvement and different enhancement analysis of images such as FCC, PCA, the study area was checked using GPS and topographic maps (1:50000) and other information. Land use units were determined using classified random sampling method. Ma...
تاثیر آموزش تفکر انتقادی به شیوه مباحثه بر روی مهارت درک متن یادگیرندگان انگلیسی به عنوان زبان خارجی
the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...

This thesis describes the use of opaque microwave bands for global estimation of precipitation rate. An algorithm was developed for estimating instantaneous precipitation rate for the Advanced Microwave Sounding Unit (AMSU) on the NOAA-15, NOAA-16, and NOAA-17 satellites, and the Advanced Microwave Sounding Unit and Humidity Sounder for Brazil (AMSU/HSB) aboard the NASA Aqua satellite. The algo...
study the correlation of snow cover area with large scale climatic signals in the south western iran
â â a great portion of precipitation in the south western iran falls in the snow formation. surface runoff produced from melting snow has an important role in the recharging ground water, surface and subsurface flows. rapid snowmelt can even cause flooding . since the snowmelt cannot be easily detected from optical satellite images, snow cover area (sca) is derived as an important hydrological...
Aeolian process and subsequently soil erosion are key factors in dryland environments. Such phenomena are related not only to geoecological factors (lithology, topography, and climatology) but also to land-use and plant cover changes. Formation of new sand dunes in Damghan explains the development of human activities over the past. The aim of this study is to explain the land use changes and th...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
The major aim of processing satellite images is to prepare topical and effectivemaps. The selection of appropriate classification methods plays an important role. Amongvarious methods existing for image classification, artificial neural network method is ofhigh accuracy. In present study, TM images of 1987, and ETM+ images of 2000 and 2006were analyzed using artificial fuzzy ARTMAP neural netwo...
