The article is devoted to the simulation of viscous incompressible fluid flow based on solving the Navier-Stokes equations. As a numerical model we chose isogeometrical approach. Primary goal of using isogemetric analysis is to be always geometrically exact, independently of the discretizati...

Depreciation has its cost and financial aspect. Depreciation can be taken as a source of funds in company in case of profit and is used to cover operating expenses. This leads to their appreciation by rate of return costs and generates fund. There are two forms of&#x...

The aim of the paper is to demonstrate the possibility of using parametric and nonparametric methods for estimating the term structure of interest rates. First, the principles of several yield curves construction are described and later, advantages and disadvantages of parametric models ...

This article is focused on a stock market portfolio optimization. The used method is a modification of traditional Markowitz model which extends the original one for adaptive approaches of parameter estimations. One of the basic factors which significantly influence optimal portfolio is ...

The Wonderland Population-Development-Environment Model (PDE) allows to study the interactions between the economic, demographic and environment factors of an idealized world, thereby enabling them to obtain insights transferable to the real world. This model was first introduced by Sanderson in ...

This paper deals with the problem of time series prediction, particularly for the economic time series. In real-life situations, there are many macroeconomic indicators affecting operating and strategic decisions of a company (Unemployment, Inflation, Gross Domestic Product, etc.). This approach ...

Kelly showed in his well-known paper that if a result of a bet or an investment is uncertain, it is not advisable to bet or invest the whole capital as this leads, with certainty, to bankruptcy. Instead of investing the whole capital Kelly proposed to invest a f...
