We consider a cyclic closed-queueing network with arbitrary service time distributions and derive first- and second-derivative estimators of some finite horizon performance metrics with respect to a ...

Covid-19 Response Minister Chris Hipkins unveiled a graph showing that second vaccine doses would be given before first jabs. A Ministry of Health staffer then tried to stop information about the ...

Having escaped prison and death, President Trump has returned to power seeking vindication and vengeance — and done more in his first 100 days to change the trajectory of the country than any ...

First, you can calculate the function’s so-called first derivative, or slope: the steepness of the function at a given point. Second, you can compute the rate at which the slope itself is changing ...

A stationary point (also known as a critical point) is a point on the graph of a function where its derivative is zero or undefined. These points are important because they often correspond to local ...

EPAM will further combine its digital transformation expertise with First Derivative’s generative AI-enabled financial and business solutions.

The direct determination of the explicitly constrained first- and second-order derivatives was also considered, and various additional expressions were obtained for generating information about the ...

Well test analyses that include the first and second derivative of pressure plotted on a semilog scale can help detect radial flow.

In this paper, the problem of calculation of first and second derivatives in general non-linear dynamical systems is addressed and an attempt of solution by means of signal flow graph (SFG) techniques ...
