Global convergence of RTLSQEP: A solver of regularized total least squares problems via quadratic eigenproblems

open access: yesMathematical Modelling and Analysis, 2008
The total least squares (TLS) method is a successful approach for linear problems if both the matrix and the right hand side are contaminated by some noise.

Investigation of $$\varXi _c^0$$ Ξ c 0 in a chiral quark model

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Recently, three new states of $$\varXi _c^0$$ Ξ c 0 were observed in the invariant mass spectrum of $$\varLambda ^+_cK^-$$ Λ c + K - by LHCb collaboration.

Numerical simulation of flow over a rough bed [PDF]

open access: yes, 2007
This paper presents results of a direct numerical simulation (DNS) of turbulent flow over the rough bed of an open channel. We consider a hexagonal arrangement of spheres on the channel bed.

Numerical analysis of the shock train evolution in planar nozzles with throat length [PDF]

open access: yesFME Transactions, 2023
In the present investigation, the behavior of compressible flow in planar nozzles with throat length is analyzed to determine the flow velocity range and pressure fluctuations in the throat section.

Direct numerical simulation of 'short' laminar separation bubbles with turbulent reattachment [PDF]

open access: yes, 2000
Direct numerical simulation of the incompressible Navier–Stokes equations is used to study flows where laminar boundary-layer separation is followed by turbulent reattachment forming a closed region known as a laminar separation bubble.

Numerical Simulation of the Hepatic Circulation

open access: yesThe International Journal of Artificial Organs, 2004
Availability of donor livers and the relatively short preservation time limit the success of liver transplantation. The use of hypothermic machine perfusion could pave the way for expansion of the donor pool. To better define optimal settings of such a device, the feasibility of using a numerical simulation model of the hepatic circulation is ...

Numerical simulation of electrocardiograms

open access: yes, 2012
This chapter presents a concise overview of various mathematical and numerical problems raised by the simulation of electrocardiograms (ECGs). A model for the propagation of the electrical activation in the heart and in the torso is proposed. Some of its mathematical properties are analyzed.

Improved Bayesian Network-Based Risk Model and Its Application in Disaster Risk Assessment

open access: yesInternational Journal of Disaster Risk Science, 2018
The application of Bayesian network (BN) theory in risk assessment is an emerging trend. But in cases where data are incomplete and variables are mutually related, its application is restricted. To overcome these problems, an improved BN assessment model
