هر ساله وقوع باران¬ های شدید باعث ایجاد شکست در تعداد زیادی از شیب های خاکی می¬شود .در طول این باران ها، سطح آب زیرزمینی بالا آمده و باعث افزایش فشار آب منفذی و کاهش پایداری شیب می¬گردد. استفاده از زهکش های افقی روشی موثر و کم هزینه جهت کنترل پایداری شیب در این حالت می باشد. با استفاده از این زهکش ها، آب پیوسته از محیط خاک جمع آوری شده و به تبع آن فشار آب منفذی کاهش و پایداری شیب افزایش می¬یابد...
the high hillsides of the tehran metropolis are prone to landslides due to the climatic conditions and the geological, geomorphologicalcharacteristics of the region. therefore, it is vitally important that a landslide susceptibility map of the region be prepared. for thispurpose, thematic layers including landslide inventory, lithology, slope, aspect, curvature, distance to stream, distance to ...
Environmental hazards are considered as one of the factors threatening human societies. Identification areas susceptible landslides risk assessment of natural hazards and management of are the essential steps in the city's watershed. The purpose of this study is landslides hazard zonation in Izeh urban watersheds of East Khuzestan. In this research First, eight layers effective in landslid...
An integrating type ADC is the most commonly used column level ADC for its simple architecture and small surface area. 12-bit Dual slope ADC is developed which has less complexity in design. This architecture has basic advantage that it eliminates the dependence of the conversion on the linearity and accuracy of the slope. The main block of this circuit is opamp. Two stage opamp is developed wh...
The field of visual perception aims to study the human visual system. It is recognized that in order to understand a system, it is important to understand its input. This has led to the sub-field of natural image statistics, which tries to understand images in statistical terms. Images’ statistical properties are usually studied by collecting a number of such images in an ensemble and computing...
