In this paper, we propose a system for the recognizing the paper currency. This is based on interesting features extractions like colors of paper currencies and correlation between images. Depending on the color of the currency is grouped into three groups-red, green and blue. In this system we are including the new currency notes of Rs.500 and Rs.2000.For Identifying the new currency we develo...
BACKGROUND A limited number of studies comparing the main risk scores (RS) for acute coronary syndromes (ACS) have been conducted and there is a limited number of long-term observations of unselected patient cohorts evaluated with the various RS. The aim of this study was to validate 5 RS (TIMI STEMI RS, TIMI NSTEMI/UA RS, GRACE RS, SIMPLE RS and ZWOLLE RS) in a Polish population and to develop...
Background: The association of lipid ratios with the severity and hospital outcome COVID-19 patients has been a topic interest in medical community. Lipids, particularly cholesterol triglycerides, play significant role human body, including cell membrane formation, energy storage regulation various biological processes. aim this study was to assess ratio patients. Methods: This observational ca...
Global solar radiation (Rs) has wide applications in several disciplines. The data of measured or predicted Rs are widely applied by solar engineers, architects, agriculturists and hydrologists. Due to the importance of Rs, several empirical models have been developed to predict its values all over the world. In this study, Angstrom model was calibrated based on the ratio of actual and possible...
این تحقیق در حوضه آبخیز رودخانه وربند لارستان واقع در استان فارس در سطحی معادل 5/925 کیلومتر مربع و با استفاده از تصاویر ماهواره ای irs و سنجندهp6 (سال 2006 ) انجام گردیده است بطوریکه با استفاده از نرم افزار erdas8.7 تصحیحات مکانی تصاویر مربوطه با استفاده از 15 نقطه و با معادله آفاین با rmse=0.42 و تصحیحات رادیومتری از طریق الگوریتم مستطیل های معادل انجام گردید و با استفاده از فاکتور شاخص مطلوب...
The Rotating-Stall (RS) through a rotor-cascade of an axial compressor were numerically investigated with an unsteady two-dimensional finite-volume density based computer code. To validate the computer code, a test case was prepared and the good agreement of the compared results has given the adequate assurance of the code. The RS was incepted with a 40% reduction in flow coefficient and a 0.4%...
The use of new methods, remote sensing (RS) and geographical information system (GIS) in zoning the water erosion in a particular geographical area (Tang-e-Bostanak catchment area) constitute the main subjects of this study. The production, combination, and composition of effective information layers in identifying these zones have been noted, highlighting the capacity of GIS and RS. In this st...
The structural complexity, especially canopy and gap structure, of old-growth forests affects the spatial variation of soil respiration (Rs). Without considering this variation, the upscaling of Rs from field measurements to the forest site will be biased. The present study examined responses of Rs to soil temperature (Ts) and water content (W) in canopy and gap areas, developed the best fit mo...
