Optimal Surplus-Dependent Reinsurance under Regime-Switching in a Brownian Risk Model

open access: yesRisks, 2021
In this paper, we consider a company that wishes to determine the optimal reinsurance strategy minimising the total expected discounted amount of capital injections needed to prevent the ruin. The company’s surplus process is assumed to follow a Brownian

Speciation, Structural Refinement, and Distribution of Ti Sites in Titanium Silicalite‐1 From 47/49Ti NMR Crystallography at 28.2 Tesla

open access: yesAngewandte Chemie, EarlyView.
Titanium silicalite‐1 (TS‐1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI‐zeolite. Applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS‐1 catalysts enables the development of an NMR crystallography protocol and the ...

Triangle Inequality for Inverse Optimal Control

open access: yesIEEE Access, 2023
Inverse optimal control (IOC) is a problem of estimating a cost function based on the behaviors of an expert that behaves optimally with respect to the cost function.

Intermolecular Nuclear Spin Hyperpolarization Transfer via Cross‐Relaxation Triggers RASER of Solute Molecules

open access: yesAngewandte Chemie, EarlyView.
Radiofrequency amplification by stimulated emission of radiation (RASER) of solutes was achieved via parahydrogen‐induced polarization (PHIP) and polarization transfer from the produced hyperpolarization donors to solutes via the intermolecular nuclear Overhauser effect (NOE).

Optimal feedback control for undamped wave equations by solving a HJB equation [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2015
In this paper, optimal feedback control for one-dimensional semi-linear wave equations is considered. The feedback law based on the dynamic programming principle requires to solve the evolutionary Hamilton-Jacobi-Bellman (HJB) equation. To avoid the so--called ``curse of dimensionality'', instead of classical discretization methods based on finite ...

A new domain decomposition method for an HJB equation

open access: yesJournal of Computational and Applied Mathematics, 2003
This note is concerned with a second-order Hamilton-Jacobi-Bellman (HJB) equation. First, the authors explain that this kind of problems can be regarded as a quasivaritional inequality problem. Further, they proceed by a domain decomposition to establish the solution.

Optimal Control of Investment-Reinsurance Problem for an Insurer with Jump-Diffusion Risk Process: Independence of Brownian Motions

open access: yesAbstract and Applied Analysis, 2014
This paper investigates the excess-of-loss reinsurance and investment problem for a compound Poisson jump-diffusion risk process, with the risk asset price modeled by a constant elasticity of variance (CEV) model.

Optimal Feedback Control of Cancer Chemotherapy Using Hamilton–Jacobi–Bellman Equation

open access: yesComplexity, 2022
Cancer chemotherapy has been the most common cancer treatment. However, it has side effects that kill both tumor cells and immune cells, which can ravage the patient’s immune system. Chemotherapy should be administered depending on the patient’s immunity

Optimal Portfolio Selection of Mean-Variance Utility with Stochastic Interest Rate

open access: yesJournal of Function Spaces, 2020
In order to tackle the problem of how investors in financial markets allocate wealth to stochastic interest rate governed by a nested stochastic differential equations (SDEs), this paper employs the Nash equilibrium theory of the subgame perfect ...
