    Purpose: This main aim of the article is to explore possible approaches to innovation marketing management by the example of urban passenger transportation. Design/Methodology/Approach: In modern conditions with the digitalization of the economy enterprises that provide transportation services are aimed at managing through artificial intelligence. Modern transport depends on the preferences of the population, based on philosophy of automation, intellectualization while at the same time is focused on the quality of transportation, elimination of losses and cost reduction. The specifics of marketing activities in the urban passenger transportation market is of particular importance in this study, taking into account the formation of the marketing innovation toolkit in the urban passenger transportation market under these specifics. Findings: A model for innovational marketing management in the urban passenger transportation sector was developed and justified, which includes six key innovation management blocks based on marketing functions: research, forecasting, information, organizational, advertising and practice. Practical implications: In practice, it is about creating a concept necessary for the provision of transport services for passengers transportation, based on the use of innovational marketing. The basic directions for the introduction of innovations at the enterprises of urban passenger transport are proposed. Originality/value: In the field of urban passenger transportation in the digital economy, new opportunities are opening up for development by applying innovational marketing, the practical implementation of which ensures increased efficiency and increases the demand for public transport services.peer-reviewe

    Optimal conditions for light pulses coherence transformation in thin nonlinear media

    Average Number of Coherent Modes for Pulse Random Fields

    Get PDF
    Some consequences of spatio-temporal symmetry for the deterministic decomposition of complex light fields into factorized components are considered. This enables to reveal interrelations between spatial and temporal coherence properties of wave. An estimation of average number of the decomposition terms is obtained in the case of statistical ensemble of light pulses.Comment: LaTeX, 10 pages, no figures; to be published in Proc.

    Purity-bounded uncertainty relations in multidimensional space -- generalized purity

    Full text link
    Uncertainty relations for mixed quantum states (precisely, purity-bounded position-momentum relations, developed by Bastiaans and then by Man'ko and Dodonov) are studied in general multi-dimensional case. An expression for family of mixed states at the lower bound of uncertainty relation is obtained. It is shown, that in case of entropy-bounded uncertainty relations, lower-bound state is thermal, and a transition from one-dimensional problem to multi-dimensional one is trivial. Results of numerical calculation of the relation lower bound for different types of generalized purity are presented. Analytical expressions for general purity-bounded relations for highly mixed states are obtained.Comment: 12 pages, 2 figures. draft version, to appear in J. Phys. A Partially based on a poster "Multidimensional uncertainty relations for states with given generalized purity" presented on X Intl. Conf. on Quantum Optics'2004 (Minsk, Belarus, May 30 -- June 3, 2004) More actual report is to be presented on ICSSUR-2005, Besan\c{c}on, France and on EQEC'05, Munich.

    Full text link
    An entanglement measure for pure-state continuous-variable bi-partite problem, the Schmidt number, is analytically calculated for one simple model of atom-field scattering.Comment: 3 pages, 1 figure; based on the poster presentation reported on the 11th International Conference on Quantum Optics (ICQO'2006, Minsk, May 26 -- 31, 2006), to be published in special issue of Optics and Spectroscop

    New uncertainty relations for tomographic entropy: Application to squeezed states and solitons

    Get PDF
    Using the tomographic probability distribution (symplectic tomogram) describing the quantum state (instead of the wave function or density matrix) and properties of recently introduced tomographic entropy associated with the probability distribution, the new uncertainty relation for the tomographic entropy is obtained. Examples of the entropic uncertainty relation for squeezed states and solitons of the Bose--Einstein condensate are considered.Comment: 18 pages, 2 figures, to be published in European Physical Journal
