PURPOSE To determine if primary open-angle glaucoma (POAG) patients can be differentiated from controls based on metabolic characteristics. METHODS We used ultra-high resolution mass spectrometry with C18 liquid chromatography for metabolomic analysis on frozen plasma samples from 72 POAG patients and 72 controls. Metabolome-wide Spearman correlation was performed to select differentially exp...
We present a complete processing line to enhance large Remote Sensing (RS) image databases in the framework of real-time 3D rendering. RS and Virtual Reality communities are faced to several challenges to deal in real-time with large image datasets while preserving high quality and realistic rendering. There is an increasing interest of InSAR (Interferometric Synthetic Aperture Radar) data, due...
The concept and the computation of terrain representation error (ETR) are investigated and total DEM error is presented as an accuracy index for DEM evaluation at a global level. A promising method of surface modelling based on the theorem of surfaces (SMTS) has been developed. A numerical test and a real-world example are employed to comparatively analyze the simulation accuracy of SMTS and th...
Nowadays there is a wide range of systems that provide an efficient and fast data capture for the DEM generation and the spread of the computer systems has allowed the use of DEM to a high number of technicians. Unfortunately, the DEM analysis tools do not have similar development. Actually, the analyses are mainly based in the application of local scale operators that provide additional inform...
هدف این تحقیق بررسی اثر توان تفکیک مدلهای ارتفاعی رقومی (dems) بر مقادیر شمارة منحنی به دست آمده از روش wi-cn بود. این روش نوین به علت استفاده از مفاهیم مازاد رطوبت مدل نیمه توزیعی topmodel به شاخص توپوگرافی و متعاقب آن مقیاس dem استفاده شده وابستگی زیادی دارد. نتایج کاربرد این روش در حوضة آبریز کسیلیان به ازای ابعاد سلولی مختلف حاکی از آن بود که متوسط شمارة منحنی حوضة به دست آمده از روش مزبور...
The shoot and root apical meristems (SAMs and RAMs, respectively) of higher plants are mechanistically and structurally similar. This has led previously to the suggestion that the SAM and RAM represent modifications of a fundamentally homologous plan of organization. Despite recent interest in plant development, especially in the areas of meristem regulation, genes specifically required for the...
The cumulative error at a point in a LiDAR-derived DEM consists of three components: propagated LiDAR-sensor error, propagated ground error, and interpolation error. To combine these error components so as to assess the vertical accuracy of a LiDAR-derived DEM, statistical methods based on the error propagation theory are often used. Due to the existence of systematic error, statistical methods...
