Summary: In this article the questions of improvement of existing methods of in-situ measurements of industrial noise sources characteristics in populated areas are considered.
Key words: industrial noise, noise characteristic, sound pressure level, field measurements, workplace, adjacent territory
Summary: The article describes the algorithm for calculating the acoustic efficiency of noise protection measures at the design stages, in new construction step or under reconstruction, by taking into account the spectral component for major traffic noise sources in populated areas.
Key words: traffic noise source, acoustic efficiency, design stages, sound pressure level, noise range.
Annotation. The use of electrostatically devoted to the development of a "Project" of Power Electrostatic Spray (EPMS).
The authors argue that using an electrostatic method spraying liquid and high potential difference electric field of the Earth, it is possible to obtain electrical energy and artificial cold.
EPMS authors positioned as an alternative to the currently used devices of solar and wind energy, and the efficiency of EPMS will be much to surpass last on all counts. Currently, the authors are ready to create an experimental pilot sample EPMS, but without the involvement of specialists from other fields of science, that is hard to do.
In this regard, one of the goals of the publication of this popular science article is bringing to "Draft" people are willing to participate.
The authors believe that the implementation of the "Project" creation of EPMS, will virtually solve the problem of energy supply of mankind now and in the long run.
Note that the use of the potential of the electric field of the Earth are made for over 200 years. There are many hypotheses projects how it can be done, but almost managed to do it exactly the authors.

Summary: Despite the fact that the existing algorithms for routing data packets are already well established, there are researchers who are trying to find alternative methods for finding the shortest path through the network. One such method uses genetic algorithms (GA). GA is an evolutionary search algorithm is used to solve optimization problems and modeling by successive selection, combination and variation of the desired parameters.
Keywords: genetic algorithm (GA), routing, shortest path, chromosome, crossover, mutation.
