Lower bounds for adaptive linearity tests [PDF]

open access: yes, 2008
Linearity tests are randomized algorithms which have oracle access to the truth table of some function f, and are supposed to distinguish between linear functions and functions which are far from linear.

Pulmonary function tests [PDF]

open access: yesRheumatology, 2008
Systemic sclerosis-associated interstitial lung disease (SSc-ILD) is the leading cause of morbidity and mortality in SSc patients. In autopsy studies, up to 70% of the SSc patients show histological evidence of lung involvement. In surgical lung biopsies from SSc-ILD patients, a pattern of non-specific interstitial pneumonia is present in a majority ...

Sperm function test

open access: yesJournal of Human Reproductive Sciences, 2015
With absolute normal semen analysis parameters it may not be necessary to shift to specialized tests early but in cases with borderline parameters or with history of fertilization failure in past it becomes necessary to do a battery of tests to evaluate different parameters of spermatozoa.

Linear operators that preserve some test functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
The paper centers around a pair of sequences of linear positive operators. The former has the degree of exactness one and the latter has its degree of exactness null, but, as a novelty, it reproduces the third test function of Korovkin theorem ...

Market-based generator cost functions for power system test cases

open access: yesIET Cyber-Physical Systems, 2018
Post-restructuring, generators are dispatched using cleared offers in the day-ahead market in the cyber-physical power system. This study proposes a novel method to design generator cost functions to emulate existing market costs for power system test ...
