Diurnal variations in helium emission

Graphic method for reducing spectrophotoelectric data of twilight helium emissio

Methods for measuring the loudness and noisiness of complex sounds

Physical and temporal aspects of sound which influence the rating of subjective noisiness are intensity, spectrum shape and bandwidth, spectral complexity, and duration. Objective rating methods include a graphic method, full octave and one-third octave methods, and methods that measure one value over all frequencies

Chart description for genus-two Lefschetz fibrations and a theorem on their stabilization

Chart descriptions are a graphic method to describe monodromy representations of various topological objects. Here we introduce a chart description for genus-two Lefschetz fibrations, and show that any genus-two Lefschetz fibration can be stabilized by fiber-sum with certain basic Lefschetz fibrations.Comment: 17 pages, 18 figure

Some Applications of the Graphic Method

There are discussed three groups of problems which are solved with the help of the graphic method

Algebra of Non-Local Charges in Supersymmetric Non-Linear Sigma Models

We propose a graphic method to derive the classical algebra (Dirac brackets) of non-local conserved charges in the two dimensional supersymmetric non-linear $O(N)$ sigma model. As in the purely bosonic theory we find a cubic Yangian algebra. We also consider the extension of graphic methods to other integrable theories.Comment: LateX file, 19 pages, figures included with epsf; file with figures has been replace

Graphic method of selection parameters V-belt transmissions

A simplified method for selecting the parameters of V-belt transmissions is considered. This method allows to choose the type of wedge belt and pulley diameters for V-belt transmission, depending on the conditions of its operation. The method is based on the norms of ISO 5292 - 80 and the national standard GOST 1284.3 – 96
