This article pursues two tasks. The first is to clarify the value and productivity of Williams’s Keywords: a vocabulary culture society (first edition 1976, second expanded 1983a) for project Cultural Studies. clarification helped, I argue, by reading it alongside Vološinov’s Marxism philosophy language (published in Russian 1929, translated into English 1973). related task speculative developm...

The application of the model geometric Brownian motion (GBM) for problem modeling and forecasting prices cryptocurrencies is analyzed. For prediction solution stochastic differential equation GBM used, which has a linear drift diffusion coefficients. Different scenarios price movement are considered.
 Keywords: (GBM), modeling, forecasting, cryptocurrency.

We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

Observed high-frequency …nancial prices can be considered as comprising two components, a true price and a market microstructure noise perturbation. It is an empirical regularity, coherent with classical market microstructure theories of price determination, that the second moment of market microstructure noise is time-varying. We study the optimal, from a …nite-sample forecast MSE standpoint, ...

In industries, how to improve forecasting accuracy such as sales, shipping is an important issue. There are many researches made on this. In this paper, a hybrid method is introduced and plural methods are compared. Focusing that the equation of exponential smoothing method(ESM) is equivalent to (1,1) order ARMA model equation, new method of estimation of smoothing constant in exponential smoot...
