A new proposal for analyzing combustion process stability based on the Hamming distance
Souza, J.W.G.; Pereira, H.B.B.; Santos, A.A.B.; Senna, V.; … - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 301-306
In this paper, the concentration of soot during controlled combustion is analyzed using two fuels: acetylene (AC) and natural gas (NG). The stability was evaluated within the spatio-temporal standards generated by the system evolution, which was based on the measuring technique known as the...

Optical diagnostics of the combustion process in a PFI SI boosted engine fueled with butanol–gasoline blend
Tornatore, Cinzia; Marchitto, Luca; Valentino, Gerardo; … - In: Energy 45 (2012) 1, pp. 277-287
Alcohol blends with hydrocarbon fuels for spark-ignition engine increase fuel octane rating and power for a given engine displacement and compression ratio. In this work, the influence of butanol addition to gasoline was investigated. The experiments were performed in a ported fuel injection...

Second-law analyses applied to a spark ignition engine under surrogate fuels for gasoline
Hongqing, Feng; Huijie, Li - In: Energy 35 (2010) 9, pp. 3551-3556
Availability analysis is applied to cylinder of a spark ignition engine during the combustion process under surrogate fuels (iso-octane, n-heptane, toluene, and methyl-cyclohexane) for gasoline using a two-zone combustion model. Special attention is given to identification and quantification of...

Understanding the thermodynamic inefficiencies in combustion processes
Tsatsaronis, George; Morosuk, Tatiana; Koch, Daniela; … - In: Energy 62 (2013) C, pp. 3-11
The thermodynamic inefficiencies associated with any energy conversion process are expressed by the exergy destruction and the exergy losses associated with the process. Combustion processes exhibit very high thermodynamic inefficiencies caused by chemical reaction, heat transfer, friction, and...

Gaussian process regression based optimal design of combustion systems using flame images
Chen, Junghui; Chan, Lester Lik Teck; Cheng, Yi-Cheng - In: Applied Energy 111 (2013) C, pp. 153-160
With the advanced methods of digital image processing and optical sensing, it is possible to have continuous imaging carried out on-line in combustion processes. In this paper, a method that extracts characteristics from the flame images is presented to immediately predict the outlet content of...

A Simple Note on Informational Cascades
Fiore, Annamaria; Morone, Andrea - In: Economics: The Open-Access, Open-Assessment E-Journal 2 (2008) 2008-1, pp. 1-21
Seminal models of herd behaviour and informational cascades point out existence of negative information externalities, and propose to ?destroy? information in order to achieve social improvements. Although in the last years many features of herd behaviour and informational cascades have been...
