Efficiency at Maximum Power of Endoreversible Quantum Otto Engine with Partial Thermalization in 3D Harmonic Potential

open access: yesJIF (Jurnal Ilmu Fisika), 2023
We study partial thermalization to the efficiency of a quantum Otto engine using Bose-Einstein Condensation in potential harmonic 3D. Partial thermalization occurs at finite-time isochoric process, preventing the medium from achieving equilibrium with ...

Enhancing Quantum Otto Engine Performance in Generalized External Potential on Bose-Einstein Condensation Regime [PDF]

open access: yes, 2023
We examine a quantum Otto engine using both Bose-Einstein Condensation (BEC) and normal Bose gas as working medium trapped in generalized external potential. We treated the engine quasi-statically and endoreversibly. Since the expansion and compression in both quasi-static and endoreversible take place isentropic, the expression of efficiency is ...

Boosting micromachine studies with Stokesian Dynamics [PDF]

open access: yesPhys. Fluids 34, 037102 (2022), 2021
Artificial microswimmers, nano and microrobots, are essential in many applications from engineering to biology and medicine. We present a Stokesian Dynamics study of the dynamical properties and efficiency of one of the simplest artificial swimmer, the three linked spheres swimmer (TLS), extensively shown to be an excellent and model example of a ...

Stroke volume estimation by thoracocardiography is better when glottis is closed [PDF]

open access: yesConference proceedings : Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 2007 (2007) 1074-7, 2008
Thoracocardiography approach pretends to non-invasively monitor stroke volume by inductive plethysmographic recording of ventricular volume curves by a transducer placed on the chest. The purpose of this study was to investigate the potential of thoracocardiography to estimate stroke volumes while apnea with open glottis.
