Efficient cyclic weighted reference counting

14th Symposium on Computer Architecture and High Performance Computing, 2002. Proceedings., 2003
Weighted reference counting is a very simple and efficient memory management system for multiprocessor architectures. This paper extends the weighted reference counting algorithm to work efficiently with cyclic data structures.

Accurate and Efficient Counting in Dynamic Networks

2014 IEEE 33rd International Symposium on Reliable Distributed Systems, 2014
Dynamic network is the abstraction of networks with frequent topology changes arising from node mobility or other reasons. With the model of dynamic network, fundamental distributed computing problems can be formally studied with rigorous correctness. In this work, we study the counting problem, which plays a significant role in many applications, such

Collection and counting efficiency

2017
Standards laboratories can provide a photocathode calibration for quantum efficiency, as a function of wavelength, but their measurements are performed with the photomultiplier operating as a photodiode. Each photoelectron released makes a contribution to the photocathode current but, if it is lost or fails to create secondary electrons at d1, it makes

Photomultiplier Single Photon Counting Efficiency

Applied Optics, 1973
An RCA C31000F (8853) photomultiplier with a cathode quantum efficiency of 5.5% (for 633-nm light) was found to have a single photon counting efficiency of only 3.3%. The difference is shown to be due to small pulses well below the single electron peak in the output pulse height spectrum. These pulses are usually below the discriminator threshold level

Factors Affecting the Counting Efficiency

2021
In the previous chapter, we realized the importance of source preparation for getting meaningful results. However, in addition to source preparation, there are many other factors, like geometrical factors, scattering of radiation, selection of radiation emitted by the isotope etc., that also need to be considered for measuring the activity of the ...

The Efficiency of Feature-Based Subitization and Counting.

Journal of Experimental Psychology: Human Perception and Performance, 2005
The enumeration of small numbers of objects (approximately 4) proceeds rapidly, accurately, and with little effort via a process termed subitization. Four experiments examined whether it was possible to subitize the number of features rather than objects present in a display.

Efficiently estimated histologic cell counts

Human Pathology, 1994
Three different estimates were compared with complete nuclear counts made over 200 fields (20 sets of 10) selected from histologic sections of 18 breast carcinomas. All counting used a 10 x 10 square grid eyepiece graticule at x 400. Two area sampling techniques agreed well with overall counts (59,210 cells counted in all 200 fields; estimates were 58 ...

High-Efficiency Triangle Counting on the GPU

2019
Triangle counting is an important step in calculating the network clustering confficient and transitivity, and is widely used in important role recognition, spam detection, community discovery, and biological detection. In this paper, we introduced a GPU-based load balancing triangle counting scheme (GBTCS), which contains three techniques.
