It is shown that the forced Korteweg-de Vries (KdV) equation studied in the recent papers [A.H. Salas, Computing solutions to a forced KdV equation, Nonlinear Anal. RWA 12 (2011) 1314-1320] and [M.L. Gandarias, M.S. Bruzón, Some conservation laws for a forced KdV equation, Nonlinear Anal. RWA 13 (2012) 2692-2700] is reduced to the classical (constant-coefficient) KdV equation by point transformations for all values of variable coefficients. The equivalence-based approach proposed in [R.O. Popovych, O.O. Vaneeva, More common errors in finding exact solutions of nonlinear differential equations: part I, Commun. Nonlinear Sci. Numer. Simul. 15 (2010) 3887-3899] allows one to obtain more results in a much simpler way. © 2012 Published by Elsevier Ltd. Source

Purpose: This study focused on foreign and domestic experience of performance-based budgeting method utilization for formation, monitoring and evaluation of the indicators that appear during preparation of budget requests, applications, and in progress reports of the budget process. Methodology: The research analyzed and visualized the algorithm of interaction between the budget process participants. We simulated the possible process of comparison of the results achieved in accordance with the strategic objectives and ways of their achievement, actual opportunity of objective evaluation of the results of budget programs and the subsequent decision making based on reporting information. Findings: The results proved individual elements that distinguish performance-based budgeting method from other methods of budgeting. In general, this method represents the system of formation (execute) of the budget of corresponding level that shows correlation between planned (made) budget expenditures and expected (achieved) results. Originality: Based on the research of successful international experience of the performance-based budgeting method we have developed practical recommendations concerning ways of improvement of implementation mechanism of this method in Ukraine. Comprehensive application of performance-based budgeting method must ensure maximum availability of budget information. This may allow people to understand whether or not the money is spent effectively, what goals are set by budget entities and public authorities, and whether these goals meet the essential needs of the community. Practical value: The problem of identification of budgeting results complicates adequate perception and rapid decision making of budget holders regarding quality and necessity of certain services provided by them. The research revealed the nature of the component of results identification in performance-based budgeting. It highlighted challenges of the results identification process in order to improve the methods of budget programs monitoring. The research results may be used by specialists in the research of the budget process and employees of financial institutions and budget holders. Source

The present paper concerns the use of multi-frequency phase method to measure the range of radar. It is shown that the measuring information about the range of targets is retained and can be obtained by appropriate mathematical transformations using the conversion of low-frequency signal with a rectangular envelope of the spectrum to the radio frequency by amplitude modulation techniques, probing targets and then converted back. © 2013 CriMiCo'2013 Organising Committee, CrSTC.

A mathematical model of a mixed empirical Poisson random cap process (RCP) on the sphere S 2 is investigated using the theory of mixed empirical marked point processes. The first-order moment measure of the RCP is proposed for spherical sets of special form. © 2011 Springer Science+Business Media, Inc. Source
