Compression ratio for the fuel: In the case of SI engines, the compression ratio of the fuel is in the range of 6 to 10 depending on the size of the engine and the power to be produced. In CI engines, the compression ratio for air is 16 to 20. The high compressi...
The results indicated that combustion chambers which were acceptable for CI mode are not appropriate for HCCI mode of engine operation. This comes from the characteristics of chemical reactions and fuel injection. The standard injectors on the market for CI and SI engines have different ...
Susceptibility mapping of shallow landslides using kernel-based Gaussian process, support vector machines and logistic regression.J. Afr. Earth Sci. 118, 53-64. [37] Conoscenti, C., Ciaccio, M., Caraballo-Arias, N.A., Gomez-Gutierrez, A., Rotigliano, E., Agnesi, V., 2015. ...
All of these things have increased the demand for low-cost micro-electronic devices [1,2]. With the research developments, the conventional electronic devices are converted into portable electronic devices, wireless sensor networks (WSNs), and micro-energy harvesting (MEH) systems. WSNs gather ...

It compares the CI H 2 engine to an equivalent diesel engine to draw fundamental insights about the mixing and combustion processes. The Converge computational fluid dynamics solver is used for all simulations. The results show that the brake thermal efficiency of the CI H 2 engine is comparable...
With LA-TDS, callers with limited English proficiency had a significant decrease in time to recognition of cardiac arrest (OR, 0.59; 95% CI, 0.41-0.84; P = .005) and dispatch of resources (OR, 0.71; 95% CI, 0.54-0.94; P = .02). Conclusions and Relevance The LA-TDS ...
