We describe a new no-reference blur index for still images based on a singular value curve (SVC). The algorithm is composed of two steps. First, the singular value decomposition is performed on the image to be blur-assessed. Then an image blur index is constructed from the singular value curve. Experimental results obtained on four simulated blur databases and on the Real Blur Image Database sh...

OBJECTIVE To present a new gestational-age-specific percentile curve for symphysis-fundus (SF) height and to determine the effects of maternal and fetal covariates. DESIGN A population-based register study. SETTING Antenatal clinics in Västra Götaland County, Sweden, between 2005 and 2010.

background methotrexate is a folic acid antagonist that has been in clinical use for five decades. its use in patients with brain tumors is primarily confined to primary central nervous system lymphoma (pcnsl), in which it is the cornerstone of chemotherapy. objectives a selective and sensitive high-performance liquid chromatography-electrospray ionization-mass spectrometry method was developed...

Wheat is an important crop of India. Precise estimates of evapotranspiration can be obtained by multiplying crop coefficients to reference evapotranspiration using readily available climatic data. PenmanMonteith equation is adopted world wide as the most reliable and accurate method for computing reference evapotranspiration. The Food and Agriculture Organization (FAO) presented crop coefficien...
