Failure of normalized ventricular filling rates to predict true filling rates

Nuclear Medicine Communications, 1987
Ventricular filling rates derived from radionuclide angiographic (RNA) time-activity curves are commonly expressed as normalized values. The assumption that normalized filling rates have a relationship to the actual filling rates was tested. RNA and contrast angiography were performed within 20 min of one another in 21 patients with widely disparate ...

Enterocystometry: Impact of Filling Rate

Journal of Urology, 2003
We evaluated different enterocystometric parameters at different filling rates.A total of 20 male patients who underwent radical cystoprostatectomy and orthotopic detubularized ileal reservoirs with at least 1 year of followup were the material of this study. Enterocystometry was done with a slow fill rate (10 ml. per minute).

Skeleton Filling Rate for Shape Recognition

2014 22nd International Conference on Pattern Recognition, 2014
As an increasing number of digital images are generated, a demand for an efficient and effective image retrieval mechanisms grows. In this work, we present a new skeleton-based shape retrieval algorithm, which starts by drawing circles of increasing radius around skeleton points.

Filling rates of long liquid-filled capillaries

Journal of Applied Physics, 1973
Fused quartz capillaries 700 and 1200 m long and 100 μm in inside diameter have been filled under hydrostatic pressure. It is verified that the rate of filling is governed by Poiseuille's law, which predicts the filled length to be proportional to the square root of the filling time. At a pressure of 270 atm, 250 m was filled in 1 h, 800 m in 10 h, and

Circle filling rate descriptor for object recognition

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
Research on shape recognition has shown that a number of recognition approaches in the literature are sensitive to rotation. In this work, we present a shape description technique, which is based on the local shape filling rate of object silhouettes.

Fill-Rate Bottlenecks in Production-Inventory Networks

Manufacturing & Service Operations Management, 1999
The bottleneck in a production-inventory network is commonly taken to be the facility that most limits flow through the network and thus the most highly utilized facility. A further connotation of “bottleneck,” however, is the facility that most constrains system-wide performance or the facility at which additional resources would have the greatest ...

Shape Filling Rate for Silhouette Representation and Recognition

2010 20th International Conference on Pattern Recognition, 2010
Research on complex shape recognition showed that the shape context algorithm is sensitive to relative position variation of articulation. Aimed at this problem, a shape recognition method is proposed based on local shape filling rate of various object silhouettes. We take each landmark point as a circle center and use as its radius.

Inheritance of Grain Filling Rate in Wheat

Cereal Research Communications, 1999
Grain weight in wheat is the product of rate and duration of grain filling (GF). GF rate represents the rate of dry matter accumulation per grain during grain fill. The lack information regarding the genetic base of GF rate prompted this study to determine kind of inheritance, genetic components and heritability for the GF rate.
