This article discusses a new approach to financial analysis of a company, using the technique known as a function of fractal interpolation, to calculate missing observations in a database containing financial information about an organization. Numerical experiments were carried out to compare the effects of using traditional linear interpolation with the function of fractal interpolation, revealing that the data adjusts better to the fractal method.

A Company

In an era of increasing energy production from renewable sources, the demand for components for renewable energy systems has dramatically increased. Consequently, managers and investors are interested in knowing whether a company associated with the semiconductor and related device manufacturing sector, especially the photovoltaic (PV) systems manufacturers, is a money-making business. We apply a new approach that extends prior research by applying decision trees (DTs) to identify ratios (i.e., indicators), which discriminate between companies within the sector that do (designated as “green”) and do not (“red”) produce elements of PV systems. Our results indicate that on the basis of selected ratios, green companies can be distinguished from the red companies without an in-depth analysis of the product portfolio. We also find that green companies, especially operating in China are characterized by lower financial performance, thus providing a negative (and unexpected) answer to the question posed in the title.

To find out the performance of a company it is necessary to have a financial analysis, where in analyzing the financial statements will get a view of the good and bad financial performance. For this reason, this study aims to analyze the effect of the Liquidity Ratio, Solvency Ratio, Profitability Ratio, and Activity Ratio on profit growth with company size as a moderating variable. The population in this study was all trade retail companies that listed in Indonesia Stock Exchange in the period 2015-2018. The research samples was determined by using purposive sampling technique, so that obtained 21 trade retail companies that quality as the sample. The analysis technique used is moderation regression analysis. Based on the research result showed that Solvability, Profitability and Activity ratios has an effect on profit growth and company size is a moderation variabel. Liquidity Ratio has no effect on profit growth and company size not a moderating variable between Liquidity on profit growth.

The existing methods and approaches for analysing an organization’s personnel capacity have been considered, a retrospective review of the well-known classifications of Russian scientists has been carried out. The authors have studied the papers devoted to the practical aspects of assessing the personnel capacity of industrial enterprises in the context of a number of areas, including: personnel management, sustainable development management, increasing the competitiveness and market value of a company. A new approach to analysing personnel capacity has been proposed in the form of assessment of personnel security or the current level of personnel risks, which are, in turn, attributed to such components of personnel capacity as qualification / working experience, ability / speed of reproduction of labor resources.

The Waves

The Pierson - Moskowitz model is only applicable to full growth state of the waves, and it has low authenticity and hopping phenomenon under the condition of offshore shallow water. This paper proposes a simulation model of offshore wave based on the improved P-M spectrum and multiple fractal interpolation methods. In order to calculate the sea wave with shallow water, a spectrum peak regulation factor and a depth of the water factor are introduced to the P - M spectrum model. Based on this model, the wavelength and wave speed are used as the initial values of wave height. Then, the amplitude and the number of iterations in diamond square fractal method are controlled to obtain the fractal static sea. In order to reduce the influence of the hopping phenomenon to the simulation authenticity, meanwhile, a multiple dynamic non-uniform interpolation method is proposed. The experimental results show that the proposed model can simulate offshore wave with better effect and in real time.

We investigate a new type of preconditioner which is based on the analytic factorization of the operator into two parabolic factors. Approximate analytic factorizations lead to new block ILU preconditioners. We analyze the preconditioner at the continuous level where it is possible to optimize its performance. Numerical experiments illustrate the effectiveness of the new approach.

In this paper, we consider fast and high-order algorithms for calculation of highly oscillatory and nearly singular integrals. Based on operators with regard to Chebyshev polynomials, we propose a class of spectral efficient Levin quadrature for oscillatory integrals over rectangle domains, and give detailed convergence analysis. Furthermore, with the help of adaptive mesh refinement, we are able to develop an efficient algorithm to compute highly oscillatory and nearly singular integrals. In contrast to existing methods, approximations derived from the new approach do not suffer from high oscillatory and singularity. Finally, several numerical experiments are included to illustrate the performance of given quadrature rules.

Performance a nalysis of an organization has a major role in setting t he strategy followed especially during the financial crisis. In what follows we performed a financial analysis, based on data from the balance sheet and profit and loss account of a company that produces and sells crystal sugar, using a system of indicators that are relevant. Using the results of this economic analysis we can draw certain conclusions according to which can forecast future developments. I tried to use a number of indicators of a system that defines, in the end, a model for analyzing the economic performance of a compa ny. The research focused on the application of the diagnostic performance of agreed financial data recorded by that company.

Taking into account that the complex grain structure is difficult to describe by using traditional analytical methods, in this study, in order to establish ceramic grain shapes of sintered BaTiO3, new approach on correlation between microstructure and properties of doped BaTiO3 ceramics based on fractal geometry has been developed. BaTiO3 ceramics doped with various dopants (MnCO3, Er2O3, Yb2O3) were prepared using conventional solid state procedure, and were sintered at 1350oC for four hours. The microstructure of sintered specimens was investigated by SEM-5300. Using method of fractal modeling a reconstruction of microstructure configurations, like grains shapes, or intergranular contacts has been successfully done. Furthermore, the area of grains surface was calculated using fractal correction that expresses the irregularity of grains surface through fractal dimension. The presented results, indicate that fractal method for ceramics structure analysis provides a new approach for describing, predicting and modeling the grain shape and relations between the BaTiO3-ceramic structure and dielectrical properties.
