On the Inherent Instability of Biocognition: Toward New Probability Models and Statistical Tools

open access: yesEntropy, 2022
A central conundrum enshrouds biocognition: almost all such phenomena are inherently unstable and must be constantly controlled by external regulatory machinery to ensure proper function, in much the same sense that blood pressure and the ‘stream of ...

Finite Element Simulation of Thermo-Mechanical Model with Phase Change

open access: yesComputation, 2021
In this work, we consider a mathematical model and finite element implementation of heat transfer and mechanics of soils with phase change. We present the construction of the simplified mathematical model based on the definition of water and ice fraction

Phonons of Phase‐Change Materials

open access: yesphysica status solidi (RRL) – Rapid Research Letters, 2022
Phase‐change materials (PCMs) undergo a reversible transition from a semiconducting to a metallic state, nicely termed “incipient metal.” This transition is driven by a Peierls distortion. A model of covalent bonding is developed in a tight‐binding scheme that accounts for the drastic evolution of some properties of PCMs, among which the Grüneisen ...

Study of phase and physical property changes during gas lift injection of high CO2‐content associated gas in the offshore M oil field

open access: yesEnergy Science & Engineering, 2023
The gas lift in the offshore M field will be performed with high CO2‐content associated gas, but the change of wellbore temperature and pressure during the injection process will lead to the change of phase and physical parameters of associated gas ...

Thermal and rheological properties of microencapsulated phase change materials [PDF]

open access: yes, 2011
The use of microencapsulated phase change materials (MPCMs) is one of the most efficient ways of storing thermal energy. When the microencapsulated phase change material (MPCM) is dispersed into the carrier fluid, microencapsulated phase change slurry ...

The Effect of a Phase Change on the Temperature Evolution during the Deposition Stage in Fused Filament Fabrication

open access: yesComputers, 2021
Additive Manufacturing Techniques such as Fused Filament Fabrication (FFF) produce 3D parts with complex geometries directly from a computer model without the need of using molds and tools, by gradually depositing material(s), usually in layers.
