Computer Simulation of Particle Size Classification in Air Separators
Cement powder size classification efficiency significantly affects quality of final product and extent of energy consumption in clinker grinding circuits. Static and dynamic or high efficiency air separators are being used widely in closed circuit with multi-compartment tube ball mills, High Pressure Grinding Rolls (HPGR) and more recently Vertical Roller Mills (VRM) units in cement plants ...
متن کاملBreast Masses Classification using a Sparse Representation
Breast mass detection and classification in mammograms is considered a very difficult task in medical image analysis. In this paper, we present a novel approach for classification of masses in digital mammograms according with their severity (benign or malign). Unlike other approaches, we do not segment masses but instead, we attempt to describe entire regions of interest (RoIs) based on a spar...
متن کاملBOSNIAK CLASSIFICATION OF RENAL CYSTIC MASSES WARREN and McFARLANE The Bosniak classification of renal cystic masses
population aged > 50 years have renal cysts [5]. Most cysts are benign and asymptomatic. A palpable mass, pain from haemorrhage into the cyst, obstructive symptoms and infections are rare presentations. A simple cyst is a fluid-filled, non-neoplastic lesion; most are unilocular, contain straw-coloured fluid, arise from the cortex and are smooth-walled. On CT they are sharply marginated, round, ...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولFeature Extraction and Classification of Mammographic Masses
The aim of this project is to classify the mammographic masses as benign or malignant using texture and shape features. A set of 73 mammograms is used for the analysis, out of which 41 are benign and 32 are malignant. Manually segmented masses are obtained from the DDSM, USF database [2]. Texture and shape features are extracted from the manually segmented masses. Stepwise linear discriminant a...
