Dilution in pressurized enclosures – critical points [PDF]

open access: yesMATEC Web of Conferences, 2022
The risk of explosion can occur in all activities involving flammable substances which, when mixed with air, can form an explosive atmosphere. Explosion protection is intended to prevent the ignition of explosive atmospheres. Pressurization, as a type of

Risk-based Approach in Obtaining and Analysing the Characteristics of Baikal Skullcap Suspension Cultures

open access: yesРазработка и регистрация лекарственных средств, 2022
Introduction. The use of biologically active compounds of Baikal skullcap (Scutellaria baicalensis Georgi) becomes especially important under pandemic conditions. The plant's value becomes the cause of overexploitation of the skullcap subterranean parts,

Critical points and the presence of pathogenic bacteria in iced beverage processing lines

open access: yesJournal of Infection in Developing Countries, 2017
Introduction: Ice can be contaminated by pathogenic bacteria. This study aimed to identify critical points in iced beverage production and distribution lines to examine the presence of pathogenic bacteria in a beverage and its processing environment, as

First-Order Comprehensive Adjoint Sensitivity Analysis Methodology for Critical Points in Coupled Nonlinear Systems. II: Application to a Nuclear Reactor Thermal-Hydraulics Safety Benchmark

open access: yesFluids, 2021
Responses defined at critical points are particularly important for reactor safety analyses and licensing (e.g., the maximum fuel and/or clad temperature).

First-Order Comprehensive Adjoint Sensitivity Analysis Methodology for Critical Points in Coupled Nonlinear Systems. I: Mathematical Framework

open access: yesFluids, 2021
This work presents the novel first-order comprehensive adjoint sensitivity analysis methodology for critical points (1st-CASAM-CP), which enables the exact and efficient computation of the first-order sensitivities of responses defined at critical points

Investigation of spectrum curves for a Sturm-Liouville problem with two-point nonlocal boundary conditions

open access: yesMathematical Modelling and Analysis, 2020
The article investigates the Sturm–Liouville problem with one classical and another nonlocal two-point boundary condition. We analyze zeroes, poles and critical points of the characteristic function and how the properties of this function depend on ...

Simple dynamical systems

open access: yesApplied General Topology, 2019
In this paper, we study the class of simple systems on R induced by homeomorphisms having finitely many non-ordinary points. We characterize the family of homeomorphisms on R having finitely many non-ordinary points upto (order) conjugacy.

Existence and multiplicity results for nonlinear problems involving the p(x)-Laplace operator [PDF]

open access: yesOpuscula Mathematica, 2014
In this paper we study the following nonlinear boundary-value problem \[-\Delta_{p(x)} u=\lambda f(x,u) \quad \text{ in } \Omega,\] \[|\nabla u|^{p(x)-2}\frac{\partial u}{\partial \nu}+\beta(x)|u|^{p(x)-2}u=\mu g(x,u) \quad \text{ on } \partial\Omega ...

Using Sigmoid Growth Models to Simulate Greenhouse Tomato Growth and Development

open access: yesHorticulturae, 2022
Mathematical modeling has been used to describe the characteristics of crop growth. Establishing a growth model can help to better understand the responses of crops to their environment and improve the efficiency of agricultural production.

UNCONVENTIONAL QUANTUM CRITICAL POINTS [PDF]

open access: yesInternational Journal of Modern Physics B, 2012
In this paper we review the theory of unconventional quantum critical points that are beyond the Landau's paradigm. Three types of unconventional QCPs will be discussed: (1) The transition between topological order and semiclassical spin ordered phase; (2) The transition between topological order and valence bond solid phase; (3) The direct second ...
