Unintended and unwanted high frequency oscillation motion is sometimes observed in small-scale experimental works and in numerical simulations when soil is subjected to simple harmonic input motions. This high frequency motion has been often attribut

An algorithm to find the roots and poles of a complex function depending on two arguments (one complex and one real) is proposed. Such problems are common in many fields of science for instance in electromagnetism, acoustics, stability analyses, spec

The sense of security is an individual’s one-sided personal expression referring to one’s awareness of existing threats and potential possibilities of their prevention. Thus we can observe a permanent development of technologies developed to meet

The finite pore volume Guggenheim–Anderson–de Boer (fpv-GAB) adsorption isotherm model has been considered as a simple tool which not only enables us to analyze the shape of isotherms theoretically, but also provides information about pore diamet

In most cases, machine components, which come in contact with each other, are made of steel. Common steel types include 100Cr6 and X105CrMo17 are widely used in rolling bearings, which are subjected to high static loads. However, more and more sophis

Using GCMC simulations, we discuss the mechanism of argon adsorption onto intercalated graphene nano-containers (NanoBuds). The mechanism is related to the shapes of the high-resolution α S -plots. Next, we have tested the applicability of these mat

Recently, a radial basis functions (RBFs) method, which was originally proposed for interpolation problems, has been developed and applied to solve partial differential equations and eigenproblems. Properties of that method (meshfree algorithm) allow
