Abstract The purpose of this investigation is to enable the solar irradiance forecast function implementing a common camera devise instead of specialized instrument thereby serve for other researches. Development of various simulated tools requires higher accuracy surrounding weather condition data. Previous studies mainly focus on the improvement of precision for professional monitor equipment i.e. total sky imager, which is limited to the scope of users. In this research, a fisheye lens graph is rectified following a particular algorithm based on the image forming principle. Moreover, solar irradiance prediction adopts the advanced BP neutral network method being proved to be valid. Final results indicate that after rectifying the special perspective images under fisheye direction, colour threshold configuration could remarkably recognize the cloud image. The conclusion shows that common camera fisheye lens coupled with BP neural network successfully predict the solar irradiance.

               The authors of the article discuss from the standpoint of the G.P. Melnikov's systemic typology of languages the phenomena characteristic for speech works of all functional styles of the modern Russian literary language that indicates violation of flectionality of the Russian language. The external preservation of inflexion and grammatical coordination in the event of violation of the forecast function in the designation of  cause-effect relationships of the developing events, does not indicate flexiveness.

The article offers a description of the general algorithm for the formation of a mathematical (stochastic) model of countering cartels as a massive negative social and legal phenomenon. The specified model allows to realize (calculate) the forecast function is a necessary element of state programs (“road maps”) to counter illegal manifestations. The formation of a mathematical model should be preceded by a stage of theoretical modeling, which establishes the constituent elements and relationships of the subject of study. It is proved that the prognostic model of the social-legal phenomenon should be based on the provisions of probability theory. A specific technique is proposed for calculating a system of stochastic indicators (mathematical expectation and standard deviation) of the corresponding model on a single methodological basis. Proposals were made for forecasting methods in relation to quantitative probabilistic models of fighting cartels. The importance of the constant (periodic) verification of the initial statistical data and the correct interpretation of the results of prediction calculations is substantiated. The directions of the practical use of the proposed model for the creation of a comparative monitoring system for the cartelization of the EAEU product markets are proposed.

First of all, this paper analyzes the calculation process of the load forecast of power system, and puts forward a new ideas of varieties of load forecasting method according to the classification on this basis, this paper will establish a global predictive function corresponding to different kinds of load forecasting methods, and designed the software on the load forecasting on the basis of such function. This paper describes the programming ideas of using the global predictive function to conduct the single forecast method and combined forecast, which demonstrates its advantages. Finally this paper has introduced the realization of global predictive function in Visual Basic language in programming, and the corresponding interface-building and use method. Actual use shows that, the use of global predictive function can significantly reduce the program size, add flexibility in the load forecasting software, which improves the scalability as well as the extensibility of the program.
