control of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولTitle Documentation of Bridges by Terrestrial Laser Scanner
Bridge structures are subjected to deterioration due to excessive usage, overloading, and aging material. For the last two decades, a significant amount research has been developed for collecting data for structural health monitoring. Yet, visual investigation with an on-site inspector remains the predominant method. This is true despite the highly subjective and time consuming aspects of this ...
متن کاملAn Effective Texture Mapping Approach for 3D Models Obtained from Laser Scanner Data to Building Documentation
Obtaining virtual models from real buildings, terrains or building works is a matter of increased interest in construction. The application of such models ranges from technical use in architecture and civil engineering, to multimedia presentation or remote visits through the web. This is becoming possible thanks to recent advances in laser scanning technology and related 3D processing algorithm...
متن کاملRobust Filtering of Airborne Laser Scanner Data for Vegetation Analysis
Airborne laser scanning (ALS), often referred to as lidar or laser altimetry, is a remote sensing technique which was originally designed to measure the topography of the Earth’s surface. While the first commercially available airborne laser scanners recorded only the time of one backscattered pulse, state-of-the-art systems record several echoes for each emitted laser pulse. Thereby a 3D data ...
متن کاملDeformation Monitor Based on 3d Laser Scanner
It introduces the methods of deformation monitoring based on 3D laser scanner. The point clouds obtained by multi-period scanning for deformation monitored object are registered. The coordinate system of point cloud is unified. Constraint stability is tested through two methods. The deformation and trends are analyzed according to the variations of coordinates of center point modeled targets an...
