Optical performance of piezoelectrically actuated MEMS tunable lenses with various pupil geometries
(Journal article; Peer reviewed, 2017)Abstract. A square geometry for the diaphragm of microelectromechanical systems (MEMS) tunable lenses with circular pupils is often used. This square diaphragm introduces aberrations that would not be present for a circular ... -
Optically induced refractive errors reduces fixation stability but saccade latency remains stable
(Journal article; Peer reviewed, 2016)The purpose of this study was to investigate the effect of optically induced refractive errors on saccade latency and fixation stability. Sixteen healthy, young adults (two males), with normal visual acuity and normal ... -
Optimal control strategies with nonlinear optimization for an Electric Submersible Pump lifted oil field
(Journal article; Peer reviewed, 2013)In an Electric Submersible Pump (ESP) lifted oil field, the ESP of each oil well should be operated inside its operating window. The total power consumed by the ESPs in the oil field should be minimized. The speed of the ... -
Optimal design and operation of a UASB reactor for dairy cattle manure
(Journal article; Peer reviewed, 2015-02-01)Optimal design and operation of a planned full-scale UASB reactor at a dairy farm are determined using optimization algorithms based on steady state simulations of a dynamic AD process model combined with models of the ... -
Optimal foraging by a large ungulate in an extreme environment: Wild mountain reindeer select snow-free feeding habitats in winter
(Journal article; Peer reviewed, 2021)Optimal foraging models predict that individual animals will optimize net energy gain by intensifying forage activity and/or reducing forage energy cost. Then, the free distribution model predicts an animal's distribution ... -
Optimal Frequency Support of Variable-Speed Hydropower Plants at Telemark and Vestfold, Norway: Future Scenarios of Nordic Power System
(Peer reviewed; Journal article, 2020)The integration of renewable resources is quickly growing in the Nordic power system (NPS), and it has led to increasing challenges for the operation and control of the NPS. Nordic countries require that the first-generation ... -
An Optimal Method for Speech Recognition Based on Neural Network
(Peer reviewed; Journal article, 2023)Natural language processing technologies have become more widely available in recent years, making them more useful in everyday situations. Machine learning systems that employ accessible datasets and corporate work to ... -
Optimal Operation of Stand-Alone Microgrid Considering Emission Issues and Demand Response Program Using Whale Optimization Algorithm
(Peer reviewed; Journal article, 2021)Microgrids are new technologies for integrating renewable energies into power systems. Optimal operation of renewable energy sources in standalone micro-grids is an intensive task due to the continuous variation of their ... -
Optimal Operation of the Peat Drying Process in Steam Tube Dryers
(Journal article; Peer reviewed, 2015-11-25)Ukraine is an energy-dependent country and aims to reduce the import of natural gas, heat, and power in general. This implies extracting fuel from her own natural resources; one relevant and readily available energy carrier ... -
Optimal Settings of Fast Active Power Controller: Nordic Case
(Chapter, 2020)The Nordic power system is continuously changing, and it has been experiencing a growing replacing of conventional power plants with renewable power plants, this together with other factors are causing reduction of the ... -
Optimal Tuning of Active Power Gradient Control for Frequency Support in Multi-Energy Systems
(Chapter, 2020)Coping with severe active power imbalances constitutes a challenging task in low inertia multi-energy systems. The phase out of the majority of conventional power plants with large size synchronous generators entails that ... -
Optimal UFLS Settings: An Assessment of Frequency System Response Indicators
(Chapter, 2020)This paper investigates the positive changes in the system frequency response indicators caused by the implementation of a set of optimal settings of an under-frequency load shedding (UFLS) scheme. The optimal UFLS scheme ... -
Optimal under-frequency load shedding setting at Altai-Uliastai regional power system, Mongolia
(Peer reviewed; Journal article, 2020)The Altai-Uliastai regional power system (AURPS) is a regional power system radially interconnected to the power system of Mongolia. The 110 kV interconnection is exceptionally long and susceptible to frequent trips because ... -
Optimism and alienation – colour schemes and soundscapes as means for the social construction of risk in climate education videos
(Peer reviewed; Journal article, 2020)While the field of climate change communication has become increasingly interested in visual representations, there has been a lack of research that attempts to capture the breadth and variety of semiotic resources being ... -
Optimization of gas velocity and pressure drop in CO2 absorption column
(Journal article; Peer reviewed, 2017)For a traditional amine-based CO2 capture system, the absorber column accounts for a significant part of the overall capital- and operating cost. One important design factor of absorber columns is the gas velocity through ... -
Optimization of lift gas allocation in a gas lifted oil field as non-linear optimization problem.
(Journal article; Peer reviewed, 2012)Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a field with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally ... -
