Do High Temperatures Affect Firm Demography? Evidence From Italy
Business Strategy and the Environment, EarlyView.ABSTRACT This study analyses the impact of high temperatures and heat stress on Italian firm demography during 2009–2022. Combining provincial‐firm‐level data with a high‐resolution multidecadal meteorological dataset, we investigate whether high temperatures—absolute and anomalous—affect firm entry and exit rates.

Numerical Comparison of Piston-, Flap-, and Double-Flap-Type Wave Makers in a Numerical Wave Tank
Journal of Marine Science and EngineeringIn naval and ocean engineering, accurate simulation of incident waves is essential for predicting the motion response of offshore structures. Traditional wave generation methods, such as piston- and flap-type wave makers, often face challenges in ...

Numerical simulation of liquid sloshing in LNG tanks using a compressible two-fluid flow model
, 2009 In this investigation the Reynolds-Averaged Navier-Stokes (RANS) equations are modified to account for variable density and viscosity of the two-fluids flow (i.e. water-air), assuming both fluids compressible.

A hidden Markov model and reinforcement learning‐based strategy for fault‐tolerant control
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study introduces a data‐driven control strategy integrating hidden Markov models (HMM) and reinforcement learning (RL) to achieve resilient, fault‐tolerant operation against persistent disturbances in nonlinear chemical processes. Called hidden Markov model and reinforcement learning (HMMRL), this strategy is evaluated in two case studies

Higher-order Spectral Method for Regular and Irregular Wave Simulations
한국해양공학회지, 2020 In this study, a nonlinear wave simulation code is developed using a higher-order spectral (HOS) method. The HOS method is very efficient because it can determine the solution of the boundary value problem using fast Fourier transform (FFT) without ...
