in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Bridge decks deteriorate over time as a result of freezing-and-thawing, heavy use, and water penetration resulting in internal defects. Ground penetrating radar (GPR) can be used as a non-destructive method for detecting such defects. Unfortunately, reflections from closely spaced objects overlap which prevents the accurate estimation of the round-trip travel time of GPR waves to the closely sp...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
روش AN-EUL روش خودکار برای برآورد مکان و محاسبه عمق و اندیس ساختاری (Structural index) (شکل) چشمههای مغناطیسی است. این روش ترکیبی از دو روش سیگنال تحلیلی و واهمامیخت اویلر است و معادلات آن از جایگذاری مشتقهای مناسب معادله اویلر در معادله سیگنال تحلیلی میدان به‌دست میآید. در این مقاله روش AN-EUL برای برآورد مکان و محاسبه عمق و اندیس ساختاری ساختارهای دوبُعدی به‌کار گرفته شده است. به‌‌این‌‌ترت...
Abstract: Image restoration is a critical step in many vision applications. Due to the poor quality of Passive Millimeter Wave (PMMW) images, especially in marine and underwater environment, developing strong algorithms for the restoration of these images is of primary importance. In addition, little information about image degradation process, which is referred to as Point Spread Function (PSF...
Methods for machine learning (support vector machines) and image processing (color deconvolution) are combined in this paper for the purpose of separating colors in images of documents. After determining the background color, samples from the image that are representative of the colors to be separated are mapped to a feature space. Given the clusters of samples of either color the support vecto...
