The device described activator of motor fuels by the patent RF No. 2411074, which is facilitated by the fractional composition of gasoline, aviation and diesels fuel, rapeseed oil, as well as modification of them hydrocarbon molecules-family in the fuel. The prospects of application of the activator. Activator tested three bench motor in Russia, environmental testing of exhaust emissions of engines in Rochester Institute (USA), control hematological indicators of eight grades of gasoline and three grades of diesel fuel, tens of chromatogram fuels before and after activation, control freezing point and smoke of diesel engines. Activator generates a unique water-fuel emulsion. Chromatograms of activated diesel and gasoline fuels showed a decrease in the proportion of heavy hydrocarbons and the formation of light molecules: hexane, heptane, 3 metal-pentane to 37 %, reducing the sulphur content from 0.032 to 0.015 %, resins from 7.4 to 0.8 mg/100 ml. In gasoline, the content of ...

To overcome the common problem, i.e., protocol complexity, of conventional underwater node estimation techniques, a statistical signal processing technique was proposed as an alternative. The technique uses cross-correlation as signal processing tool and hence it is called cross-correlation based underwater node estimation technique. This technique can overcome the protocol complexities, human interaction, over cost, etc., of conventional techniques. However, to introduce the readers with different technical aspects regarding this technique, the paper is introduced. We have used mean, and standard deviation as our estimation parameter to estimate nodes. At the same time, we have illustrated a brief discussion on effect of signal length, underwater bandwidth, etc., simultaneously in this paper. This writing can boost the researches in this field.

Due to the increase of consumption in the world of energy and the pollution caused by fossil fuel combustion processes, it is necessary to generate new technologies for the use of alternative fuels, allowing to reduce the dependence on fossil fuels such as oil, gas and coal. In general, the combustion processes of fossil fuels produce greenhouse gases which increase the temperature of the environment and the deterioration of the ozone layer. Chemical equilibrium was used to estimate the species produced by adiabatic gasification with different air-vapor mixtures. By running the NASA CEA software (chemical equilibrium with applications), a thermochemical simulation was performed under two parameters: the equivalence ratio (ER) defined as stoichiometric air/air supplied to the reactor (1.5-6) and the steam-fuel ratio (0-1). Thus, the syngas composition showed the following ranges: CO (0% -14.7%), H 2 (0% - 36.7%), CH 4 (0% -4.3%), Co 2 (17% -22.7%). The calorific value of t...
