in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...

this descriptive study is carried out to determine the effectiveness of family planning programmes in iran for years 1991-96. the study revealed the following outlines: contraceptives prevalence rates increased from 42% to 67% during years 1991-96. zaro couples years of protection increased for norplant, injectable contraceptive, iud, vasectomy and tubectomy, but for candom it is decreased in y...

background measures taken over the past four years in greece to reduce pharmaceutical expenditure have led to significant price reductions for medicines, but have also changed patient cost-sharing rates for prescription drugs. this study attempts to capture the resulting increase in patients’ out-of-pocket (oop) expenses for prescription drugs during the 2011-2014 period.   methods the authors ...

The glomerular filtration rate (GFR) is widely considered the best overall index of renal function. The Schwartz equations are designed for measuring the GFR in children between 1 and 16 years of age. In the present study, we investigated the percentiles of the GFR in a general population of Iranian children with no known renal disease via the 2009 Schwartz equations (updated and combined equat...

We present an exact formula for the computation of the interference rate of radiation in the case of two charges revolving with constant angular velocity at opposite ends of a diameter in a fixed circle. The formula is valid for arbitrary velocities of the charges, and can be easily studied by numerical methods, even for velocities very close to the velocity of light. For ultrarelativistic moti...

This paper addresses the issues of charging, rate control and routing for a communication network carrying elastic tra c, such as an ATM network o ering an available bit rate service. A model is described from which max{min fairness of rates emerges as a limiting special case; more generally, the charges users are prepared to pay inuence their allocated rates. In the preferred version of the mo...

Carbon-coated olivine NaFePO(4) (C-NaFePO(4)) spherical particles with a uniform diameter of ∼80 nm are obtained by chemical delithiation and subsequent electrochemical sodiation of carbon-coated olivine LiFePO(4) (C-LiFePO(4)), which is synthesized by a solvothermal method. The C-NaFePO(4) electrodes are identical (particle size, particle size distribution, surface coating, and active material...
