Control Valve Flow Coefficients
Journal of Transportation Engineering, 1985The flow coefficient for a control valve is an important hydraulic parameter that is used to select and design the controls for a closed conduit system. The parameter is used to determine flow capacities, valve positioning, and energy losses of the system.

Control Coefficients and the Matrix Method
1990When we developed the matrix method (Fell & Sauro, 1985), we were aiming to find a quick route for the evaluation of flux control coefficients in terms of elasticities, either algebraically for the general case, or numerically in specific instances where the values of the elasticities were known.

Rate control on correlation coefficient of network delay
GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004The demand to access multimedia data such as live video is increasing due to the spread of broadband access network. However, the Internet only provides so called best-effort service. The network condition of the Internet shows fluctuation. Delivering video without any control causes degradation of the final video quality.

Control charts for the coefficient of variation
2017The subject of this essay is the investigation and presentation of control charts for the coefficient of variation CV. We investigated and presented a sufficient number of control charts that have been proposed during the last ten years. Some of those are simple, other use specific techniques in order to more efficiently detect changes in the CV.

A Design and Evaluation of Coefficient of Variation Control Chart
2020Statistical Process Control (SPC) is widely used in practice, and the control chart is a main tool in SPC. The control chart monitors process quality and detects process variations in real time to reduce the defective products. Regulatory maps are used in clinical trials and agronomic industries, and the mean and variance are not constants, and the ...

Adaptive control of non-linear systems with unknown virtual control coefficients
International Journal of Adaptive Control and Signal Processing, 2000The author proposes an adaptive control strategy for a nonlinear system in (triangular) strict feedback form with an unknown coefficient. Based on a backstepping approach, a smooth adaptive feedback law is derived. Via a suitable Lyapunov function the desired control performance of the closed loop system is shown.

A note on the controllability of jump diffusions with linear coefficients
IMA Journal of Mathematical Control and Information, 2012We investigate the approximate controllability property for a class of linear stochastic equations driven by independent Brownian motion and Poisson random measure. The paper generalizes recent results of Buckdahn et al. (2006, A characterization of approximately controllable linear stochastic differential equations.
