A model is proposed for the effect of dose-rate on the survival curve. The model leads to a set of differential equations, which are solved numerically. The parameters of the model have been fitted to published data on the survival of HeLa S3 cells, and a satisfactory fit obtained.

GENERATING RATING CURVE AND RATING TABLE OF GOLARCHI MINOR
Big Data in Water Resources Engineering (BDWRE), 2022Hydrologists must have huge theoretical and practical knowledge of irrigation networks such as rivers, canals, streams, channels, and minors. Because whole irrigation system relies on a gauge and discharges relationship which is essential for controlling floods, water resource management, and hydrologic modeling. The true and consistent figures of flow

Extrapolation of rating curves
Hydrotechnical Construction, 1981A linear relation was established between vav and hav for open channel flows, which is confirmed by the hydrometric data for a large number of rivers and gauging sites. This relation is a more accurate characteristic of the river flow than that obtained by the Chezy formula, which requires, moreover, the determination of additional parameters.

Catch Curves and Mortality Rates
Transactions of the American Fisheries Society, 1961Abstract The assumptions necessary to obtain a valid estimate of survival rate from a single catch curve are discussed. An example of the best estimate of survival rate and its variance is worked out for the case that age is known exactly for the entire sample. A test for validity of the model is illustrated. Methods of estimating the survival rate are

Curve Fitting for Error Rate Data
2019 XVI International Symposium "Problems of Redundancy in Information and Control Systems" (REDUNDANCY), 2019The problem of fitting experimental or simulated error rate data with analytical curves is analyzed. The comparison is made between the maximum likelihood (ML) fitting and widely used minimization of squared error in log domain (Log-MSQ). It is shown that ML fitting demonstrates lower sensitivity to a particular sample realization of error events, and ...

Zero curves can be derived from government bonds or LIBOR/swap instruments. The LIBOR/swap term structure offers several advantages over government curves, and is a robust tool for pricing and hedging financial products. Correlations among governments and other fixed-income products have declined, making the swap term structure a more efficient hedging

Reproduction of Hysteresis in Rating Curves
Journal of Hydraulic Engineering, 2004The well-known Jones formula has long been used to convert a stage hydrograph to a discharge hydrograph under many unsteady flow situations. The logic behind the formula can be explained with the use of the approximate convection–diffusion equation in its development. However, its applicability criterion has not yet been quantified.
