The procedure involves two levels of test abstraction; firstly a bench test-rig, designed to fit in a hydraulic test machine, using real valve and seat insert specimens simulating combustion loading, and secondly a motorised cylinder-head, to study the effect of impact on valve closure without the application of combustion loading.
In the tensile test, six levels of test temperature (−30, 0, 20, 50, 80 and 110 °C) and five levels of crosshead speed (2, 10, 100, 500 and 1500 mm/min) were designed.
There are three levels of testing, Basic, Standard, and Extended.
The significance of the CNVs was evaluated in two levels of statistical tests: (i) SNP site-based testing to measure the disease-association on a specific SNP site and (ii) Window-based testing to measure the CNV-pattern differentiation in and around the selected SNP site.
Some of the players were unfamiliar with the test so the first two levels of the test were incorporated into the warm-up to familiarise players with the test protocol.
We also selected two levels of pre-test risk for the at-risk relative, each with a further three levels of post-test risk.
Two levels of pressure support were tested: clinically set level (PS basal) and 50%% increase (PS + 50).
There were 18 eligible wards in Trust A and 14 in Trust B. Two levels of the intervention were tested: Basic Feedback and Feedback Plus.
In terms of the achievement tests, two levels of the IEP were included in the analysis for the first research question: Level 2 and Bridge.
In order to enhance the knowledge of the behavior of such connection, this paper presents experimental results for monotonic and cyclic tests (for two levels of strain rate) on stapled and threaded nailed connections.
