We reexamine the spectroscopic underpinnings of recent suggestions that [O I] and [Fe II] lines from the Orion H II region are produced in gas where the iron-carrying grains have been destroyed and the electron density is surprisingly high. Our new observations show that previous detections of [O I] 5577 were dominated by telluric emission. Our limits are consistent with a moderate density (≈ 1...
This thesis work is aiming for detecting and localizing different classes of objects in natural images. For this, we use an algorithm that first detects objects using Implicit Shape model (ISM), then, with patch based class segmentation, verifies the hypothesis. This algorithm is able to achieve a high detection rate on both rigid and articulated objects. The thesis also proposes a novel multi-...
As the closest radio galaxy, Centaurus A is a powerful laboratory for the X-ray study of radio-emitting structures and their interactions with the hot interstellar medium (ISM). This paper details our interpretation of the remarkable X-ray enhancement which caps the inner southwest radio lobe, at a radius of about 6 kpc from the galaxy center. The shell of X-rayemitting gas is hotter than the a...
با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...
Purpose The millennia long struggles of various oppressed groups have over time illuminated widespread social injustices, organically leading to the recognition yet further injustices captured by umbrella discriminatory isms, such as racism, sexism, classism, ableism, anti-Semitism, ageism, heterosexism and many others. In recent years, debate has become increasingly fierce, polarized even phys...
The aim of this study is to investigate the capability of the image source method (ISM) for predicting medium and high frequency flexural vibrations of damped convex polygonal thin plates including various boundary conditions. Besides its classical use in room acoustics, ISM has already been applied to polygonal plates comprising simply supported and roller supported edges. Such boundaries incl...
