POSSIBILITIES OF USING MULTI-ZONE SATELLITE IMAGES AND GIS TECHNOLOGIES FOR MONITORING PIPELINE SYSTEMS

Multi Resolution Fuzzy Segmentation of Satellite Images

Using GIS data and satellite images to manage hazard zone in earthquake

One of the quickest and most efficient methods to study urbanism conditions and determine critical conditions of regions and rate of losses after earthquake is the use of aerial photos. The critical conditions are more severe in cities and mountainous regions due to the steep slope of traffic routes, snow and frosting, and use of aggregates. Using satellite images and GIS maps different regions...

Mine Subsidence Monitoring Using Multi-source Satellite SAR Images

Ground subsidence due to underground mining has posed a constant threat to the safety of surface infrastructure such as motorways, railways, power lines, and telecommunications cables. Traditional monitoring techniques like using levels, total stations and GPS can only measure on a point-by-point basis and hence are costly and time-consuming. Differential interferometric synthetic aperture rada...

The Integration of GPS, Satellite Radar Interferometry, and GIS Technologies for Ground Subsidence Monitoring

A variety of deformation surveying techniques have been extensively used for measuring the pattern of ground subsidence. These include precise levelling, total station traversing, aerial photogrammetry and GPS surveys. The impact on the surface infrastructure of underground coal mining to the southwest of Sydney is continuously monitored using a combination of these techniques. Since 2002, expe...

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
