TRANSITION IN THE FRETTING PHENOMENON [PDF]

open access: yesFiabilitate şi Durabilitate, 2022
Fretting regimes were first mapped by Vingsbo. In a similar way, three fretting regimes will be considered: stick regime,slip regime and mixed regime.

Bubble Column Reactors: the Variables Influencing the Mono-dispersed Homogeneous Flow Regime

open access: yesChemical Engineering Transactions, 2023
The fluid dynamics of large-diameter bubble columns explicates in six flow regimes emergin upon an increase in the gas flow rate and can be described and predicted via correct modelling of the flow regime transition coordinates. This study focuses on the

Cold-to-warm flow regime transition in snow avalanches [PDF]

open access: yesThe Cryosphere, 2018
Large avalanches usually encounter different snow conditions along their track. When they release as slab avalanches comprising cold snow, they can subsequently develop into powder snow avalanches entraining snow as they move down the mountain. Typically,

Modelling Thermally Induced Non-Equilibrium Gas Flows by Coupling Kinetic and Extended Thermodynamic Methods

open access: yesEntropy, 2019
Thermally induced non-equilibrium gas flows have been simulated in the present study by coupling kinetic and extended thermodynamic methods. Three different types of thermally induced gas flows, including temperature-discontinuity- and temperature ...

Unitary Matrix Models and Phase Transition [PDF]

open access: yes, 1997
We study the unitary matrix model with a topological term. We call the topological term the theta term. In the symmetric model there is the phase transition between the strong and weak coupling regime at $\lambda_{c}=2$. If the Wilson term is bigger than

Analysis of the Moment Method and the Discrete Velocity Method in Modeling Non-Equilibrium Rarefied Gas Flows: A Comparative Study

open access: yesApplied Sciences, 2019
In the present study, the performance of the moment method, in terms of accuracy and computational efficiency, was evaluated at both the macro- and microscopic levels.

Autonomy as Anticipation of the World of Work at School

open access: yesSwiss Journal of Sociology, 2019
Schools are under increasing pressure to prepare students for the transition to post-compulsory education and vocational training. Beyond the support of the students’ professional orientation, the focus is on students’ learning of soft skills.

The Behavior of Earnings Quality in Different Business Cycles Using Panel Smooth Transition Regression (PSTR) Model [PDF]

open access: yesبررسی‌های حسابداری و حسابرسی, 2018
This paper investigates the threshold effects of business cycles on earnings quality for the period of 2005 to 2015, using Panel Smooth Transition Regression (PSTR) model as one of the most prominent regime-switching models.

Quantum Zeno effect as a topological phase transition in full counting statistics and spin noise spectroscopy [PDF]

open access: yes, 2014
When the interaction of a quantum system with a detector is changing from weak to strong coupling limits, the system experiences a transition from the regime with quantum mechanical coherent oscillations to the regime with a frozen dynamics.
