Constraining uncertainty in climate sensitivity : an ensemble simulation approach based on glacial climate
… For this objective we first generate a large ensemble of model simulations, covering different feedback strengths, and then request their consistency with present-day observational data and proxy-data from the Last Glacial Maximum (LGM). Our analyses are based on an ensemble of fully-coupled …

Climate impact of aviation NOx̳ emissions : radiative forcing, temperature, and temporal heterogeneity
… mW/m² per Tg of NOx emissions). However, few simulations assess the surface air temperature (SAT) response, or conduct a large ensemble simulation with climate feedback in the cases where SAT is predicted. We aim to quantify the climate forcing and temperature response of aviation NOx …

Equilibrium and Non-equilibrium Monte Carlo Simulations of Microphases and Cluster Crystals
… systems, we here develop novel Monte Carlo simulation methods. A thermodynamic integration scheme allows us to calculate the free energy of specific modulated phases, while a [N]pT ensemble simulation approach, in which both particle number and lattice spacing fluctuate, allows us to explore …

Adjoint Methods and Inverse Modeling for Process Variation Analysis in Silicon Photonics
… cost of time, either the computational cost from simulation, or the cycle length of fabrication process. Therefore, here we explore some of the powerful tools that can shorten the simulation or experiment time, and provide alternative, efficient, or economical approaches for process variation …
