DOI: 10.1007/s11831-018-9275-2
Abstract: We study the numerical approximation of partial differential equations with random input data. Such problems arise when the uncertainty of the underlying system is taken into account using a probability setting. The main goal of… read more here.

DOI: 10.1080/03461238.2021.1938199
Abstract: We study an optimal dividend problem for an insurer who simultaneously controls investment weights in a financial market, liability ratio in the insurance business, and dividend payout rate. The insurer seeks an optimal strategy to… read more here.

DOI: 10.1080/24705314.2023.2168171
Abstract: ABSTRACT Structures are usually designed to undergo some yielding, cracking and damage during any catastrophic events like earthquakes. It is necessary to identify these damage locations to avoid the failure of the structure. In this… read more here.

DOI: 10.1364/ol.475601
Abstract: The interest in high quality factor (high-Q) resonances in metasurfaces has been rekindled with the rise of the bound states in the continuum (BIC) paradigm, which describes resonances with apparently limitlessly high quality-factors (Q-factors). The application of… read more here.
