A linear programming-based framework of interval power flow analysis for distribution systems

open access: yesInternational Journal of Electrical Power & Energy Systems
The interval power flow (IPF) method is widely employed to address the uncertainties of renewable energy sources (RESs) in power systems. However, limited research exists on the application of mathematical optimization-based approaches to compute IPF ...

Analysis of linear mechanical structures with uncertainties by means of interval methods

open access: yesComputer Assisted Methods in Engineering and Science, 2023
One of the simplest ways of representation of uncertain or inexact data, as well as inexact computations with them, is based on interval arithmetic. In this approach, an uncertain (real) number is represented by an interval (a continuous bounded subset)

Mechanical Models with Interval Parameters [PDF]

open access: yes, 2005
In this paper we consider modelling of composite material with inclusions where the elastic material properties of both matrix and inclusions are uncertain and vary within prescribed bounds.

On the nonlinearity of quantum dynamical entropy

open access: yes, 2018
Linearity of a dynamical entropy means that the dynamical entropy of the n-fold composition of a dynamical map with itself is equal to n times the dynamical entropy of the map for every positive integer n.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

An Application of Interval Arithmetic for Solving Fully Fuzzy Linear Systems with Trapezoidal Fuzzy Numbers

open access: yesAdvances in Fuzzy Systems, 2018
We present a method for solving fully fuzzy linear systems using interval aspects of fuzzy numbers. This new method uses a decomposition technique to convert a fully fuzzy linear system into two types of decomposition in the form of interval matrices. It

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Controllability Robustness of Linear Interval Systems with/without State Delay and with Unstructured Parametric Uncertainties

open access: yesAbstract and Applied Analysis, 2013
The robust controllability problem for the linear interval systems with/without state delay and with unstructured parametric uncertainties is studied in this paper.

Robust $H_{\infty}$ Interval Observer for Linear Systems With a Controllable Convergence Rate: A Parametric Method

open access: yesIEEE Access, 2019
In this paper, the design method of a robust interval observer for linear systems with time-varying disturbances is proposed. First, the H∞ gain performance is established by constructing the transfer function from disturbances to error dynamic ...

Dynamics of piecewise contractions of the interval

open access: yes, 2012
We study the asymptotical behaviour of iterates of piecewise contractive maps of the interval. It is known that Poincar\'e first return maps induced by some Cherry flows on transverse intervals are, up to topological conjugacy, piecewise contractions ...
