Optimal Pricing of Production Changes in Cascaded River Systems with Limited Storage
(Chapter, 2019)Optimization of hydroelectric power production is often executed for river systems consisting of several powerplants and reservoirs located in the same region. For hydropower stations located along the same river, the ... -
Optimal production and maintenance scheduling for a multiproduct batch plant considering degradation
(Peer reviewed; Journal article, 2020)Performance decay due to asset degradation is an important constraint in industrial production and therefore needs to be actively considered. This paper focuses on short-term scheduling for multiproduct batch processes ... -
Optimal Quadrature for univariate and tensor product splines
(Journal article; Peer reviewed, 2016)Numerical integration is a core subroutine in many engineering applications, including the finite element method (FEM). Isogeometric analysis is a FEM technology that uses smooth B-spline and NURBS basis functions. ... -
Optimal recovery of a radiating source with multiple frequencies along one line
(Peer reviewed; Journal article, 2020)We study an inverse problem where an unknown radiating source is observed with collimated detectors along a single line and the medium has a known attenuation. The research is motivated by applications in SPECT and beam ... -
Optimal recovery of thermal energy in liquid air energy storage
(Peer reviewed; Journal article, 2021)The increasing share of renewables in energy systems requires energy storage technologies to handle intermittent energy sources and varying energy sinks. Liquid air energy storage (LAES) is a promising technology since it ... -
Optimal release time determination using FMOCCP involving randomized cost budget for FSDE-based software reliability growth model
(Peer reviewed; Journal article, 2019)This paper presents a software reliability growth model (SRGM) based on a fuzzy stochastic differential equation (FSDE) approach. The software shall comprise of dependent and independent main and sub-components owing to a ... -
Optimal reliability growth program for repairable and warranted products
(Chapter, 2019)Considering a two-dimensional and non-renewing free repair warranty (NFRW) policy, this paper proposes a modified reliability growth model to support the decision making of the manufacturer on the choice of a reliability ... -
Optimal Renewable Energy Distribution Between Gasifier and Electrolyzer for Syngas Generation in a Power and Biomass-to-Liquid Fuel Process
(Peer reviewed; Journal article, 2022)By adding energy as hydrogen to the biomass-to-liquid (BtL) process, several published studies have shown that carbon efficiency can be increased substantially. Hydrogen can be produced from renewable electrical energy ... -
Optimal Risk Adoption and Capacity Investment in Technological Innovations
(Journal article; Peer reviewed, 2021)Technological innovations often formulate new market regimes and create incentives to abandon existing, less attractive ones. However, this decision depends not only on market forces, such as economic and technological ... -
Optimal scheduling of flexible thermal power plants with lifetime enhancement under uncertainty
(Peer reviewed; Journal article, 2021)Renewable energy sources have been the focal point to decarbonise the power sector. The large deployment of these intermittent power generation units requires mechanisms to balance the grid. Thermal power plants can provide ... -
Optimal scheduling of multiple spatio-temporally dependent observations for remote estimation using age-of-information
(Journal article; Peer reviewed, 2022)This article proposes an optimal scheduling policy for a system where spatiotemporally dependent sensor observations are broadcast to remote estimators over a resource-limited broadcast channel. We consider a system with ... -
Optimal scheduling of multiple spatio-temporally dependent observations using age-of-information
(Chapter, 2020)This paper proposes an optimal scheduling policy for a remote estimation problem, where spatio-temporally dependent sensor observations are broadcasted to remote estimators. At each time instant only observations from a ... -
Optimal Scheduling of Plug-in Electric Vehicles in Distribution Systems Including PV, Wind and Hydropower Generation
