A comparison of classical scheduling approaches in power-constrained block-test scheduling [PDF]

open access: yes, 2000
Classical scheduling approaches are applied here to overcome the problem of unequal-length block-test scheduling under power dissipation constraints. List scheduling-like approaches are proposed first as greedy algorithms to tackle the fore mentioned ...

Comparison of the power of statistical tests in connection with the discussion about the reproducibility criterion

open access: yesСтатистика и экономика, 2018
The criterion of reproducibility, as well as its functioning in post-non-classical science, are discussed in the Russian methodology of science. At the same time, critics avoid statistical calculations in their arguments.

A Hybrid Model to Simulate Test Cases of Electrical Power Systems

open access: yesApplied Sciences, 2020
The development of solution algorithms for power system problems is based on hypothetical test systems and test cases. These systems are very scarce, and the degree of variability is relatively low.

The Power of Rank Tests [PDF]

open access: yesThe Annals of Mathematical Statistics, 1953
Simple nonparametric classes of alternatives are defined for various nonparametric hypotheses. The power of a number of such tests against these alternatives is obtained and illustrated with some numerical results. Optimum rank tests against certain types of alternatives are derived, and optimum properties of Wilcoxon’s one- and two-sample tests and of

Hypothesis Testing on the Location Parameter of a Skew-Normal Distribution (SND) with Application

open access: yesITM Web of Conferences, 2018
This work deals with testing a hypothesis on the location parameter (μ) of a skew-normal distribution (SND) based on a random sample of size n. The details of this work can be summarized in four major components: (a) First we review some useful results ...

Development of a movable standing wave resonant test system for fundamental power couplers with an extraordinary power gain

open access: yesPhysical Review Accelerators and Beams, 2022
Off-line high-power tests of the fundamental power couplers prior to their on-line operations are of importance for ensuring their operating reliability and stability. To test the couplers using a limited power supply effectively, a movable standing wave
