In this paper, we investigate the structure of the Fučík Spectrum for the second order boundary value problem with one non-local boundary condition. We provide a new compact form of the implicit description of the Fučík Spectrum in the first quadrant. Presented compact form of...

The problem when a random variable exceeds some boundary is very often studied problem in many fields of science. The classical approach focuses on situation when random variable overlap a fix value. More general methods interested in situation with two random variables and the...

The purpose of this work is to study the existence of a solution to the nonlinear second order ordinary differential equation u''(x) + m2 u(x) + g(x, u) = f(x) , x ∈ [0, T] , u(0) = u(π) = 0 , where m ∈ N, g is a Carathéodory function,...

This paper is focused on a possible methodology for estimating of regression curve by nonparametric kernel regression approach. The main objective is a description of nonparametric regression function with using Nadaraya-Watson approach including a real data application for beer consumption in&#x...

The paper investigates sports betting arbitrage and demonstrates it on data from English football between seasons 2013–14 and 2017–18. Several strategies of arbitrage betting are proposed, e.g., preference for favourite or outsider, and they are used for betting in four top level Englis...

Finite element model of an airfoil segment made of laminated glass fiber composite is created. The model is calibrated using data from experimental tests, namely the modal characteristics and vibrations measured with laser sensors in selected locations. Passive monitoring method is applied&#...

This paper is focused on the possible methodologies for comparing two time series by estimating the probability that both time series will increase or decrease (of course in probability) in the same time. It can be considered as the specific measure of dependence (more precise...

The article deals with a description of results from research and development of a radial compressor stage with 3D rotor blades. The experimental facility and the measurement and evaluation process is described briefly in the first part. The comparison of measured and computed charac...

The aim of this paper is to present our recent existence and uniqueness results for a one-dimensional damped model of a suspension bridge and compare them to previous results for either damped or non-damped one-dimensional beam models.

Big data technology (BDT) is a new technological paradigm that is driving the entire economy, including low-tech industries such as agriculture where it is implemented under the banner of precision farming (PF). Big data analytics system will then provide pilot managers with highly ...

In this study, the influence of main laser cladding parameters on the final microstructure of cladded WC-NiCrBSi coating is discussed. As the used powder is the blend of 60% tungsten carbide spherical particles and 40 % NiCrBSi matrix, the carbides’ morphology and distribution in&#...

Laser remelting of thermally sprayed coatings is a promising possibility how to improve their functional properties. However, it requires precise control of processing parameters to achieve desired depth of remelting. In this study, the near-infrared (NIR) camera is used to measure the ...

The influence of heat treatment on the microstructure, mechanical and sliding wear properties of Hastelloy C-276 HVOF sprayed coatings was evaluated. The applied furnace heat treatment modified the coatings microstructure, leading to precipitation hardening and oxidation of inter-splat boundaries, but...

In the contribution we talk about using geometric software in the courses of geometry at University of West Bohemia. We present a few examples we use in the practical lesson of course Differential geometry.

There are two main reasons for changing rules in the ice hockey. The first reason is a safety of players and spectators and the second reason is an attractiveness of matches. This paper studies effects of rule changes that were made because of the second reason, e.g....

In this paper, we use random matrix theory to analyse eigenvalues and see if there is a presence of pertinent information by using Marčenko–Pastur distribution. Thus, we analyse cross correlations between price fluctuations of different stocks using methods of random matrix theory. More...

In this paper we will investigate one certain application of polynomial 2-surfaces possessing the polynomial area element in the Minkowski space $\R^{3,1}$, where they coincide with the so called MOS surfaces (i.e., medial surface transforms with rational domain boundaries). We formulate...

This paper is devoted to the construction of polynomial surfaces with Pythagorean normals (PN surfaces) interpolating given data subject to prescribed constraints on the surface area of the patch. This is a problem analogous to the interpolation with Pythagorean hodograph (PH) curves sa...

The home team advantage in association football is a well known phenomenon. The aim of this study is to offer a different view on the home team advantage. Usually, in association football, each two teams – team A and team B – play twice in a season. Once as...

Cajal-like interstitial cells (IC-LC) play important role in both physiological and pathological function of the bladder. The authors developed relative simple mathematical model consisting of five nonlinear ODEs. The model accuracy was verified using published experimental results. Deeper analysis of...
