The Application of the γ-Reθt Transition Model Using Sustaining Turbulence
Energies, 2022 The freestream turbulence intensity is an important parameter for Tollmien–Schlichting waves and is also used as one of the key variables for the local- and transport-equation-based transition model in the simulations.

Investigated stress-strain relationships of municipal solid waste incineration bottom ash
Geomatics, Natural Hazards & Risk, 2020 To investigate the stress-strain relationship of municipal solid waste incineration bottom ash (MSWIBA), taking MSWIBA samples with a dry density of ρd = 1.5 g/cm3 as examples, a series of consolidated drained triaxial tests were carried out on MSWIBA ...

Observation Model for Indoor Positioning
Sensors, 2020 The IEEE 802.11mc WiFi standard provides a protocol for a cellphone to measure its distance from WiFi access points (APs). The position of the cellphone can then be estimated from the reported distances using known positions of the APs. There are several

Transition prediction in the Ising-model
PLoS ONE, 2021 Dynamical systems can be subject to critical transitions where a system’s state abruptly shifts from one stable equilibrium to another. To a certain extent such transitions can be predicted with a set of methods known as early warning signals.

Dilatancy transition in a granular model [PDF]
, 2010 We introduce a model of granular matter and use a stress ensemble to analyze shearing. Monte Carlo simulation shows the model to exhibit a second order phase transition, associated with the onset of dilatancy.Comment: Future versions can be obtained from:

Extension of the KDO turbulence/transition model to account for roughness
Advances in Aerodynamics, 2022 Wall roughness significantly influences both laminar-turbulent transition process and fully developed turbulence. A wall roughness extension for the KDO turbulence/transition model is developed.

Continuous phase transition in a spin-glass model without time-reversal symmetry [PDF]
, 1998 We investigate the phase transition in a strongly disordered short-range three-spin interaction model characterized by the absence of time reversal symmetry in the Hamiltonian.

Modelling low income transitions [PDF]
Journal of Applied Econometrics, 2004 AbstractWe examine the determinants of low income transitions using first‐order Markov models that control for initial conditions effects (those found to be poor in the base year may be a non‐random sample) and for attrition (panel retention may also be non‐random). The model estimates, derived from British panel data for the 1990s, indicate that there

Doubling the Accuracy of Indoor Positioning: Frequency Diversity
Sensors, 2020 Determination of indoor position based on fine time measurement (FTM) of the round trip time (RTT) of a signal between an initiator (smartphone) and a responder (Wi-Fi access point) enables a number of applications.

Semiparametric transition models [PDF]
Econometric Reviews, 2021 A new semiparametric time series model is introduced – the semiparametric transition (SETR) model – that generalizes the threshold and smooth transition models by letting the transition function to be of an unknown form. Estimation is based on a combination of the (local) least squares estimations of the transition function and regression parameters ...
