This contribution is devoted to the wavelet based adaptive numerical solution of the Black-Scholes equation for pricing European options. We apply the Crank-Nicolson scheme with Richardson extrapolation for time discretization ...

Differential evolution algorithms represent nowadays an efficient framework to cope with complex optimization tasks with many variables and involved constraints. Nevertheless, the classic differential evolution algorithms ...

Solving problems in geometry, whether planar or spatial, is for students generally more difficult than solving problems in other branches of mathematics, e.g. in arithmetic or in algebra. Therefore, it is necessary to ...

Financial management in agricultural enterprises is affected by a range of factors that are not present in other sectors. One of the factors that affect the performance of enterprises is the legal or organizational form ...

The objective of this work was to investigate dimensional parameters of 3D printed parts from glass ceramic photopolymer before and after debinding and sintering in a kiln. During experiments batches of green bodies were ...

The research claims that traditions are not static. They develop and adapt based on the present situation. Due to the recent climate extremes coming to formerly mild climate locations, their architectures can learn from ...

Measurement of thermal resistance of polymer sheets and fibrous layers is important in various applications including those within the engineering, ergonomics, clothing design and personal protective equipment fields. ...

Thanks to their chemical and physical properties, the cutting fluids can significantly affect the process of machining - the use of cutting fluid reduces the roughness of the machined surface and increases the tool life. ...

The actual trend in the automotive industry is to discover electric vehicles and bring them to the market in a few years. There are some pilot products in electric cars production and still a lot of open questions connected ...

Nanoparticles (NPs) of TiO2 or SiO2 (size of 10–25 nm) added to a cooling lubricant emulsion (CLE) have a positive effect on the machining process due to a reduction in the average friction coefficient, a reduction in the ...
