Optimal generic attack against basic Boneh-Boyen signatures
(Springer-Verlag, 2022-11-19)The Boneh-Boyen digital signature scheme is a pairing-based signature scheme that features short signatures consisting of one group element, the minimum possible size. In contrast to earlier short signature schemes such ... -
Optimal inventory decisions for a risk-averse retailer when offering layaway
(Elsevier, 2020-07-01)Layaway allows economically disadvantaged budget-constrained consumers to purchase expensive items through amortized payments and nominal program fees, as opposed to using high-interest financing options such as credit ... -
Optimal inventory decisions when offering layaway
(Taylor & Francis, 2019)This paper presents an inventory management policy for a retailer offering a layaway programme. Layaway is a service provided by retailers that allows budget constrained consumers who have sufficiently high valuations to ... -
Optimal Investing Strategies for Participating Contracts
(Elsevier, 2017-03)Participating contracts are popular insurance policies, in which the payoff to a policyholder is linked to the performance of a portfolio managed by the insurer. We consider the portfolio selection problem of an insurer ... -
Optimal investment-reinsurance strategies with state dependent risk aversion and VaR constraints in correlated markets
(Elsevier, 2019-03)In this paper, we investigate the optimal time-consistent investment–reinsurance strategies for an insurer with state dependent risk aversion and Value-at-Risk (VaR) constraints. The insurer can purchase proportional ... -
An optimal power management strategy for power split plug-in hybrid electric vehicles
(Inderscience, 2012-10-22)Model Predictive Control (MPC) can be an interesting concept for designing a power management strategy for Hybrid Electric Vehicles (HEVs) according to its capability of online optimisation by receiving current information ... -
Optimal processing route for the utilization and conversion of municipal solid waste into energy and valuable products
(Elsevier, 2018-02-10)A systematic design of municipal solid waste (MSW) management system can lead to identify a promising and/or sustainable way of handling MSW by processing it into energy and valuable products. In this study, a systematic ... -
Optimal randomized ordering policies for a capacitated two-echelon distribution inventory system
(Elsevier, 2018-10-01)We propose a new formulation for controlling inventory in a two-echelon distribution system consisting of one warehouse and multiple non-identical retailers. In such a system, customer demand occurs based on a normal ... -
Optimal sampling methods for modelling the occupancy of Arctic grayling (Thymallus arcticus) in the Canadian Barrenlands
(Canadian Science Publishing, 2017)In occupancy models, imperfect detectability of animals is usually corrected for by using temporally-repeated surveys to estimate probability of detection. Substituting spatial replicates for temporal replicates could be ... -
Optimal Sensor Configuration and Fault-Tolerant Estimation of Vehicle States
(SAE International, 2013-04-08)This paper discusses observability of the vehicle states using different sensor configurations as well as fault-tolerant estimation of these states. The optimality of the sensor configurations is assessed through different ... -
Optimal Torque Control for an Electric-Drive Vehicle with In-Wheel Motors: Implementation and Experiments
(SAE International, 2013-04-08)This paper presents the implementation of an off-line optimized torque vectoring controller on an electric-drive vehicle with four in-wheel motors for driver assistance and handling performance enhancement. The controller ... -
Optimization and control of a thin film growth process: A hybrid first principles/artificial neural network based multiscale modelling approach
(Elsevier, 2018-11-02)This work details the construction and evaluation of a low computational cost hybrid multiscale thin film deposition model that couples artificial neural networks (ANNs) with a mechanistic (first-principles) multiscale ... -
Optimization of lipid production in Chlorella vulgaris for biodiesel production using flux balance analysis
(Elsevier, 2019-01-15)Microalgae, the world’s largest group of photosynthetic organisms, convert atmospheric CO2 to polar and neutral lipids using sunlight, which after esterification can be utilized for biodiesel production. In the present ... -
Optimization of muscle activation schemes in a finite element neck model simulating volunteer frontal impact scenarios
(Elsevier, 2020-03-07)Neck muscle activation is increasingly important for accurate prediction of occupant response in automotive impact scenarios and occupant excursion resulting from active safety systems such as autonomous emergency braking. ... -
Optimization of the hydrodynamic characteristics of a karst conduit with CFPv2 coupled to OSTRICH
(Elsevier, 2018-12-01)In order to better define the characteristics of a karst conduit, an integrated hydrogeological study including numerical modeling using CFPv2 is conducted at a karst aquifer in the Zagros Mountain Region of Iran. The ... -
Optimizing hydrological consistency by incorporating hydrological signatures into model calibration objectives
(American Geophysical Union, 2015-05-31)The simulated outcome of a calibrated hydrologic model should be hydrologically consistent with the measured response data. Hydrologic modelers typically calibrate models to optimize residual-based goodness-of-fit measures, ... -
‘Optimulation’ in Chemical Reaction Engineering: The Oxidative Coupling of Methane as a Case Study
(ACS, 2018-06-07)The optimization of reacting systems, including chemical, biological, and macromolecular reactions, is of great importance from both theoretical and practical standpoints. Even though several classical deterministic and ... -
An Optokinetic Nystagmus Detection Method for Use With Young Children
(Institute of Electrical and Electronics Engineers, 2015-03-05)The detection of vision problems in early childhood can prevent neurodevelopmental disorders such as amblyopia. However, accurate clinical assessment of visual function in young children is challenging. optokinetic nystagmus ... -
