A NEW TEST OF TOTAL SPERMICIDAL POWER
Reproduction, 1962A new test for total spermicidal power is described. The procedure involving mixing semen and spermicidal solution is carried out at 35-37 degrees C. The spermatozoa are exposed to attack for 60 seconds and the mixture is observed microscopically. If moving spermatozoa are observed the test is scored "fail." If there are no signs of life the test ...

A Comparison Between the Power of the Durbin-Watson Test and the Power of the BLUS Test
Journal of the American Statistical Association, 1969Abstract In an earlier paper [5] the authors compared the power of the BLUS test with the probability of a correct decision of the Durbin-Watson bounds test. A method to compute the distribution of the Von Neumann ratio under the null hypothesis and under the alternative hypothesis was given.

The revealing power of a test case
Software Testing, Verification and Reliability, 1992Abstract‘Propagation, infection, and execution analysis’ (termed PIE) is used for predicting where faults can more easily hide in software. To make such predictions, programs are dynamically executed with test cases, and information concerning the test cases is collected into a histogram, each bin of which represents a single test case.

A test of long-run purchasing power parity
Economics Letters, 2001There is a continuing debate whether purchasing power parity holds as a long-run equilibrium relationship. This note applies an exact small-sample, pointwise most powerful invariant unit root test to annual, long-horizon real exchange rates. This test finds clear and consistent evidence in favor of the true purchasing power parity relationship.

1999
In Chapter 3, you were introduced to some practical, easily computed tests of hypotheses. But are they the best tests one can use? And are they always appropriate? In this chapter, we consider the assumptions that underlie a statistical test and look at some of a test’s formal properties: its significance level, power, and robustness.

A Power Analysis of Tests for Paired Lifetime Data
Lifetime Data Analysis, 2005A power analysis is used to compare tests developed for a new lifetime model applicable for certain paired-data experiments. Two pivotal quantities are available for exact parametric testing of the equality of the marginal survival distributions. Here, the power of each test will be calculated to find the more powerful test.

Test results of a HTS power transformer connected to a power grid
Physica C: Superconductivity, 2002Abstract A 22 kV/6.9 kV–1 MVA high-Tc superconducting (HTS) power transformer has been developed as a prototype with single-phase part of a 3 MVA HTS power transformer. The prototype unit is cooled by a continuous subcooled liquid nitrogen (LN2) supply system with cryocoolers.

A Test of Power, a Test of Faith
1972The conclusion of the Twelve Years’ Truce gave the United Provinces an interlude of peace abroad, but at home it was followed by one of the most severe conflicts to afflict the Republic in its entire history. The struggle which marked the decade from 1609 to 1619 pitted the Arminians or Remonstrants against the Gomarians or Contra-Remonstrants, but ...

Design and testing of a power electronic synthetic inductor
International Journal of Electronics, 2007In many applications inductors are often replaced with circuits, typically based upon operational amplifiers, which emulate an inductance for reasons of package size or to closer approximate the desired ideal behaviour. A power electronic synthetic inductor offers an alternative circuit which can emulate an inductor with relatively low power ...

Reliability of a New Medicine Ball Throw Power Test
Journal of Applied Biomechanics, 2017The purpose of this study was to examine the reliability of a new upper body medicine ball push-press (MBP-P) test. Twenty-three strength trained volunteers performed a series of supine MBP-P throws using loads representing 5% and10% of their 5RM bench press (5 repetitions at each load).
