In-Cylinder Equivalence Ratio Measurements in an EGR Equipped Engine
Journal of Engineering for Gas Turbines and Power, 2010 A single-cylinder natural gas fueled engine equipped with an exhaust gas recirculation (EGR) system was ignited using a laser. The broadband emission from the spark kernel was spectrally resolved, and the peaks corresponding to Hα, N, and O atoms were measured for a range of conditions with global equivalence ratios ranging between 0.6 and 1.0 and for ...

The ratio of equivalent mutants: A key to analyzing mutation equivalence
Journal of Systems and Software, 2021Abstract Mutation testing is the art of generating syntactic versions (called mutants) of a base program, and is widely used in software testing, most notably the assessment of test suites. Mutants are useful only to the extent that they are semantically distinct from the base program, but some may well be semantically equivalent to the base program,

SAE Technical Paper Series, 1977
<div class="htmlview paragraph">Mixture strength, or equivalence ratio, is the primary factor affecting the fuel consumption and exhaust emissions of a gasoline engine. A new instrument has recently been developed to monitor equivalence ratio. The response time of the instrument is 1/2 second, so that the effects of engine transient conditions ...

Ratios and equations equivalent to the meyer ratio and equation for acids
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19711. Ratios and equations equivalent to the Meyer ratio and equation for acids were derived. 2. The molar extinction coefficients of anions and nondissociated molecules of acids can be determined in certain cases according to the Meyer equation. 3.

Fourier-ratio deconvolution and its Bayesian equivalent
Micron, 2008We discuss how an inner-shell electron energy-loss spectrum can be processed using Bayesian (maximum-entropy or maximum-likelihood) deconvolution to simultaneously remove plural scattering and improve the energy resolution. As in Fourier-ratio deconvolution, a low-loss spectrum (recorded from the same area of specimen) is used as a kernel or resolution

Likelihood Ratio Tests for the Non Equivalence of Means
Communications in Statistics - Simulation and Computation, 2011We derive likelihood ratio (LR) tests for the null hypothesis of equivalence that the normal means fall into a practical indifference zone. The LR test can easily be constructed and applied to k ≥ 2 treatments. Simulation results indicate that the LR test might be slightly anticonservative statistically, but when the sample sizes are large, it always ...

Four Ways to Determine Equivalent Ratios
Mathematics Teaching in the Middle School, 2018Ratios and proportions are important concepts that occur in real life, but they are difficult to learn and complicated to teach (Lamon 2007). In general, proportional reasoning in the middle grades is an area in need of attention because of its connection to later concepts (Ojose 2015).
