Accelerating techniques on nested decomposition
(2017)In this paper, we consider the nested decomposition method in the context of multistage stochastic problems with scenario trees where we contribute with improvements in accelerating convergence to optimum. We first propose ... -
Active control of wind turbines through varying blade tip sweep
(2019)In this research work an introduction to the concept of an actively controlled horizontal axis wind turbine through varying blade tip sweep, is presented. The concept refers to variable tip swept rotor blades, that have ... -
Analysis of the impact of automatic shading control scenarios on occupant's comfort and energy load
(2021)Building envelopes should be responsive to boundary conditions changing in short-time, daily, or seasonal patterns. To this end, adaptive facades provide the ability to react, or benefit from, outdoor fluctuations and ... -
Application of a One-Dimensional Computational Model for the Prediction of Deposition from a Dry Powder Inhaler
(2017)Background: Accurate prediction of the regional deposition of inhaled dry powders as a function of powder properties and breathing pattern is a long-term research goal for pulmonary drug delivery. In the present work, ... -
Approaching reactive species in the frame of their clinical significance: A toxicological appraisal
(2020)Redox biology and toxicology are interrelated fields that have produced valuable evidence regarding the role and clinical significance of reactive species. These issues are analyzed herein by presenting 6 arguments, as ... -
Bayesian estimation of the true prevalence of paratuberculosis in Hungarian dairy cattle herds
(2020)Paratuberculosis is a chronic incurable disease caused by Mycobacterium avium subsp. paratuberculosis (MAP), which leads to extensive economic losses on dairy farms, and may also pose serious public health risk to the ... -
Bootstrap-based testing approaches for the assessment of the diagnostic accuracy of biomarkers subject to a limit of detection
(2019)Assessment of the diagnostic accuracy of biomarkers through receiver operating characteristic curve analysis frequently involves a limit of detection imposed by the laboratory analytical system precision. As a consequence, ... -
Bubble rise dynamics in a viscoplastic material
(2015)The axisymmetric dynamics of a bubble rising in a Bingham fluid under the action of buoyancy is studied. The Volume-of-Fluid (VOF) method is used to solve the equations of mass and momentum conservation, coupled to an ... -
CARROT - A tool for fast and accurate soft error rate estimation
(2006)We present a soft error rate (SER) analysis methodology within a simulation and design environment that covers a broad spectrum of design problems and parameters. Our approach includes modeling of the particle hit at the ... -
Chirality transfer from a 3D macro shape to the molecular level by controlling asymmetric secondary flows
(2022)Homochirality is a fundamental feature of living systems, and its origin is still an unsolved mystery. Previous investigations showed that external physical forces can bias a spontaneous symmetry breaking process towards ... -
Comparison of journal bearing operational magnitudes calculated using various modern theoretical simulation models
(2001)This paper presents comparative theoretical results regarding the computational estimation of operational magnitudes of hydrodynamically lubricated finite journal bearings which are either smooth or of negligible roughness ... -
Comparison of quadratic and non-linear programming (QP and NLP) optimization models in groundwater management
(2004)This project is concerned with the comparison of two algorithms used in groundwater management models based on Quadratic Programming (QP) and Non-linear Programming (NLP) models,. A quadratic objective function is used and ... -
A computational study of austenite formation kinetics in rapidly heated steels
(2007)Surface hardening of steels involves rapid austenitization and subsequent quenching of the surface. The resulting extent of hardening largely depends on the rate of austenitization of the surface under the applied high ... -
Confidence intervals for differences between volumes under receiver operating characteristic surfaces (VUS) and generalized Youden indices (GYIs)
(2018)This article explores both existing and new methods for the construction of confidence intervals for differences of indices of diagnostic accuracy of competing pairs of biomarkers in three-class classification problems and ... -
Control and optimization of the Corona effects and breakdown of small rod-plate air gaps stressed by dc and impulse voltages
(2013)In the present paper methods of controlling Corona and breakdown in small rod-plate air gaps are investigated. Combining experimental and simulation-theoretical work, it is resulted that when the rod's diameter is bigger, ... -
Decentralized blockchain-based consensus for Optimal Power Flow solutions
(2021)We design, implement and analyze a decentralized consensus algorithm based on the blockchain technology for the solution of the Optimal Power Flow problem. The proposed algorithm enables independent power grid nodes, without ... -
Detecting different topologies immanent in scale-free networks with the same degree distribution
(2019)The scale-free (SF) property is a major concept in complex networks, and it is based on the definition that an SF network has a degree distribution that follows a power-law (PL) pattern. This paper highlights that not all ... -
Detection of future changes in trends and scaling exponents in extreme short-term rainfall at selected stations in Slovakia
(2018)This paper analyses projected changes in short-term rainfall events during the warm season (April - October) in an ensemble of 30 regional climate model (RCM) simulations. The analysis of trend changes and changes in scaling ... -
