Experimental determination of the electron-avalanche and the electron-ion recombination coefficient [PDF]

, 1980
The electron-ion recombination coefficient γ and the avalanche coefficient δ = (α − a) · vd, where α and a are the ionizat ion and attachment coefficients respectively and vd the drift velocity of the electrons, have been experimentally determined in a ...

Markov Properties of Electrical Discharge Current Fluctuations in Plasma

, 2011
Using the Markovian method, we study the stochastic nature of electrical discharge current fluctuations in the Helium plasma. Sinusoidal trends are extracted from the data set by the Fourier-Detrended Fluctuation analysis and consequently cleaned data is

Modification of Roughness Coefficients of Water Distribution Network Using Optimization Method [PDF]

رویکردهای نوین در مهندسی عمران, 2018
Due to the breadth and complexity of water distribution networks, modeling of these networks is essential for proper utilization and proper network management. Determination of network coefficients is the more importance in network modeling.

Discharge coefficients for ogee spillways

Water Supply, 2022
Abstract Discharge over an ogee weir is related to the length of the weir, upstream total head above the weir crest and the discharge coefficient. The discharge coefficient is influenced by several factors; in this study, some parameters that influence discharge coefficients of ogee weirs are investigated. These factors include: the weir

Determination of Coefficients of Groundwater Flow in Multilayered Aquifers [PDF]

, 1986
It is difficult to determine the coefficients of groundwater flow from the data which were obtained from the drawdown test in a multiaquifer system. In this paper, new methods of analyzing drawdown-tests are developed and illustrated with the example to ...

Coefficient of Discharge of the Piston Valve

Transactions of the Japan Society of Mechanical Engineers, 1954
By the use of oil, the present authors have determined the coefficients of discharge, C, of the piston valves with a single hole, and have obtained an experimental formula, where C is represented as a function of hole diameter, d (mm), and of opening ratio of the hole, m.

Development of a novel clinical scoring system for on-farm diagnosis of bovine respiratory disease in pre-weaned dairy calves. [PDF]

, 2014
Several clinical scoring systems for diagnosis of bovine respiratory disease (BRD) in calves have been proposed. However, such systems were based on subjective judgment, rather than statistical methods, to weight scores.
