We prove an analogue of Fekete's subadditivity lemma for functions several real variables which are subadditive in each variable taken singularly. This extends both the classical case one variable, and a similar result integer variables. While doing so, we that with property mentioned above bounded every closed subset their domain. The arguments expand on those Chapter 6 E. Hille's 1948 textbook.

This study deals with the main characteristics of the Maximal Length, Gold, Kasami, Walsh and variable-length orthogonal codes and their functions in code-division multiple access(CDMA) networks. The important properties of the sequences are examined. A method of multiple spreading for channelization and scrambling in CDMA is described. Auto and cross correlation properties of some codes are me...

The paper describes one of possible approaches to control of multi-variable control loops. In the approach to control is used the so called RGA (Relative Gain Array) method, simple approach to ensure of invariance of control loop and simple approach to a design of the so called primary controllers. The RGA serve to determine the optimal input-output variable pairings especially for a multi-vari...
