Wave theory analysis of the Hungarian vehicle fleet especially focusing on emission categories

Szendro G., Horvath E., Torok A.

Production Engineering Archives

2015

Vol. 8, No. 3

2--5

Toyotarity means the improvement of quality, decrease of production costs and production time, increase of safety and morale. With the help of tools of toyotarity strategic factors can be determined, production or service problems can be revealed. In this paper tools of toyotarity are obtained to analyse the driving factors of Hungarian vehicle fleet and car renewal. Product analysis was conducted on the basis of wavetheory.

Solution of the Rayleigh equation with the use of computer algebra

Gorelov S., Zharov V., Khlopkov Y.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

1998

nr 8

195-198

A solution procedure based on computer-algebra methods is applied to the eigenvalue problem for the Rayleigh equation with the Blasius velocity profile. The procedure can be used to manipulate power series containing a large number of terms. An expression for the phase velocity of the lowest-order harmonic is obtained in the form of a series in the wave-vector components. Representation of the series in terms of Fade approximants is considered with a view to improving their convergence.
