We consider the integrated fractional Brownian motion with Hurst index 0 < H < 1. The main aim consists in studying its links with the quasi-helix with approximately stationary increments class of centered Gaussian processes. More precisely, we compute some well-chosen quantities which depend on the moments of the integrated fractional Brownian motion. Firstly, we check if one can obtain appropriate...
The paper suggests an adaptation of a grouping genetic algorithm for solving the capacitated p-median problem. We propose a new encoding of the individual solutions that enables an efficient implementation of the crossover operation. A hybrid metaheuristic that combines the grouping genetic algorithm with the post-processing solver is proposed as well. Numerical experiments performed on benchmark...
The paper is concerned with an application of the simplified impact model of critical infrastructure safety related to climate-weather change process to safety and risk prediction for Baltic Oil Terminal Critical Infrastructure operating at the variable climate-weather conditions. There are presented the identified oil terminal safety parameters and the climate-weather change process parameters and...
Electrocardiogram (ECG) signals obtained during driving simulations provide an indication of physiological response during complex driving tasks. The present study contributes to the literature on this response through the analysis of features in time-frequency representations, specifically, continuous wavelet transforms (CWTs). The main frequency band in the CWT of ECG signals, which corresponds...
