Optimal business model adaptation plan for a company under a transition scenario
Tackling climate change is one of the biggest challenges of today. Limiting climate change translates to drastically cutting carbon emissions to net zero as soon as possible. More and more commitments have been made by various authorities and companies to mitigate their GHG emissions accordingly, notably the Paris Agreement in 2015 that sets the ’w...
$hp$-optimal convergence of the original DG method for linear hyperbolic problems on special simplicial meshes
We prove hp-optimal error estimates for the original DG method when approximating solutions to first-order hyperbolic problems with constant convection fields in the $L^2$ and DG norms. The main theoretical tools used in the analysis are novel $hp$-optimal approximation properties of the special projector introduced in [Cockburn, Dong, Guzman, SINU...
Power system planning in the energy transition era: the case of Vietnam's Power Development Plan 8
This review examines Vietnam's eighth Power Development Plan (PDP8), analyzing how it reveals tensions between traditional energy planning concepts and emerging realities. PDP8 aimed to balance renewable energy and natural gas priorities amidst Vietnam's rapidly changing energy landscape. The planning process struggled to incorporate uncertainties ...
Mean-field limits for Consensus-Based Optimization and Sampling
For algorithms based on interacting particle systems that admit a mean-field description, convergence analysis is often more accessible at the mean-field level. In order to transpose convergence results obtained at the mean-field level to the finite ensemble size setting, it is desirable to show that the particle dynamics converge in an appropriate...
Constructive approaches to concentration inequalities with independent random variables
Concentration inequalities, a major tool in probability theory, quantify how much a random variable deviates from a certain quantity. This paper proposes a systematic convex optimization approach to studying and generating concentration inequalities with independent random variables. Specifically, we extend the generalized problem of moments to ind...
