Issue of telecom channel organization between different devices is studied. Types of devises and equipments is observed. Estimation of cost for variants of telecom channel organization is carried out.
Feature of the development of any complex electronic equipment is the need to solve multiobjective problems with complex view of the objective function and the set of constraints. In particular, as the criteria for evaluation and comparison of variants of structural and algorithmic implementation of SAС can be used: the depth of control, reliability of the whole system, including controls, speed, cost, flexibility and versatility.
The article is devoted to the analysis of results of application profitable and cost-based approaches to estimation of cost of the real estate objects which frequently appears much below their real market prices. Opportunities of the comparative approach use to an estimation of the real estate objects are considered, allowing to receive parameters of a real supply and demand in the market, and also in its frameworks of a mark method as alternatives of existing ways of an estimation.
This paper aims at explaining the differences in valuation of banking firms in Russia through the impact of selected elements of corporate governance. We rely upon value-based management theory to test the hypothesis that expenses on corporate governance system create shareholder value. The price at which share stakes are acquired by strategic foreign investors is for us a criterion of market-proven value, so we use the standard valuation tool, i.e. price-to-book-value of equity (P/BV) multiple, as the dependent variable. The set of corporate governance parameters whose materiality for a would-be external investor we would like to test includes: the degree of concentration of ownership and control; maturity of corporate governing bodies; degree of Board independence; qualification of external auditors; stability of governing bodies (Management Board and Board of Directors); and availability of external credit ratings from the world’s leading rating agencies. We test our approach on a sample of acquisition deals and public offerings over the period 2004-2008 that we develop for the first time. Firstly, we find out which factors are statistically significant and relevant to a bank’s selling price. Secondly, a least squares multiple linear regression model is devised to check how each individual variable impacts the dependent variable. We discover that external investors attach value to high concentration of ownership, external credit rating coverage, stability of the Board of Directors, and involvement of well-established external auditors. Investors of a strategic nature tend to pay a higher acquisition premium. Independence of the Board of Directors might be perceived by external strategic investors as a disadvantage and might destroy shareholder value.
This article is the first part of the historical review of the occurrence and development of concep- tual approaches to measuring goodwill in economic science since the end of the 19 century to the 70-ies of 20 century. The problem of goodwill measurement arose in economic science at the end of the 19th century and still discussed in the academic and practitioner communities around the world. Despite numerous studies and the adoption of accounting standards issued by various pro- fessional organizations internationally, existing opinions on this issue vary and change frequently. The need to preserve the established recognition criteria, on the one hand, and the need to provide useful information, on the other, has led to a number of controversial issues in the measurement and recognition of goodwill. In the study we analyze the historical experience in the form of goodwill perceptions, identifying historical patterns suitable for improvement of modern theory and practice of measuring goodwill. Methodological basis of the study consists of the works of distinguished sci- entists in the fields of accounting, international and generally accepted standards of accounting and reporting. The authenticity of the author’s findings confirmed by a logical use of scientific methods such as historical-and-comparative, historical-and-typological and historical-and-system method. The author track back the transformation of methods of measuring goodwill in academic research and normative documents of the nineteenth and twentieth centuries. Separate section is devoted to modern concepts of goodwill measurement, which represents an alternative to the existing account- ing standards. а gradual, cumulative and cyclical process of development of methods for measuring goodwill was identified. We found that in periods of economic growth the paradigm of current value usually dominates, while in periods of recession the historical cost paradigm is rolled back.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
