New Aspects of Solution Feasibility in a Context of Personalized Therapy Optimization

open access: yesApplied Sciences, 2022
In this work, the feasibility of a personalized therapy design is considered. We attempt to determine whether all of the obtained results of computer simulations should be presented to medical personnel.

Numerical Infeasibilities of Nanofibrous Mats Process Design

open access: yesApplied Sciences, 2021
A new computer-aided method to design electrospun, nanofibrous mats was implemented and tested. In this work, the standard nonlinear algebraic model led to the terminal fiber diameter FD being examined in detail.

An α-Model Parametrization Algorithm for Optimization with Differential-Algebraic Equations

open access: yesApplied Sciences, 2022
An optimization task with nonlinear differential-algebraic equations (DAEs) was approached. In special cases in heat and mass transfer engineering, a classical direct shooting approach cannot provide a solution of the DAE system, even in a relatively ...

Dragged metrics [PDF]

open access: yesGeneral Relativity and Gravitation, 2013
We show that the path of any accelerated body in an arbitrary space-time geometry $g_{ }$ can be described as geodesics in a dragged metric $\hat{q}_{ }$ that depends only on the background metric and on the motion of the body. Such procedure allows the interpretation of all kind of non-gravitational forces as modifications of the metric of space-

Coulomb drag of viscous electron fluids: Drag viscosity and negative drag conductivity

open access: yesPhysical Review B, 2023
We show that Coulomb drag in hydrodynamic bilayer systems leads to additional viscosity terms in the hydrodynamic equations, i.e., the drag and drag-Hall viscosities, besides the well-known kinematic and Hall viscosities. These new viscosity terms arise from a change of the stress tensor due to the interlayer Coulomb interactions.

Model-Based Fiber Diameter Determination Approach to Fine Particulate Matter Fraction (PM2.5) Removal in HVAC Systems

open access: yesApplied Sciences, 2021
Particulate Matter (PM) is a general term to classify air pollutants consisting of airborne particles. The particles vary in composition and size, and the sizes of particles range from 2.5 µm (PM2.5) to 10 µm (PM10).

“Houses. Cats. Cars. Trees. Me”: Outward and Inward Journeys in Joe Brainard’s Collage Travelogues

open access: yesStudia Anglica Posnaniensia, 2021
This article examines two brief travelogues by the American writer and visual artist Joe Brainard (1942–1994) as formally unique fusions of the travel journal and literary collage, in which the experience of travel becomes a catalyst for introspection ...

Turbulent drag on a low-frequency vibrating grid in superfluid He-4 at very low temperatures [PDF]

open access: yes, 2012
We present measurements of the dissipative turbulent drag on a vibrating grid in superfluid He-4 over a wide range of (low) frequencies. At high velocities, the dissipative drag is independent of frequency and is approximately the same as that measured ...

Semiclassical theory of electron drag in strong magnetic fields [PDF]

open access: yes, 2004
We present a semiclassical theory for electron drag between two parallel two-dimensional electron systems in a strong magnetic field, which provides a transparent picture of the most salient qualitative features of anomalous drag phenomena observed in ...
