Optimal Control Design For Robust Fuzzy Friction Compensation in a Robot Joint
(2009)This paper presents a methodology for the compensation of nonlinear friction in a robot joint structure based on a fuzzy local modeling technique. To enhance the tracking performance of the robot joint, a dynamic model is ... -
Optimal Coordination of Directional Overcurrent Relays Using Hybrid Firefly–Genetic Algorithm
(2023-07-12)The application of directional overcurrent relays (DOCRs) plays an important role in protecting power systems and ensuring their safe, reliable, and efficient operation. However, coordinating DOCRs involves solving a highly ... -
Optimal design of climate change policies through the EU's rural development policy : Final Report
(European Commission, 2013-02-28)In 2013 the current Rural Development Programme (RDP) comes to an end and consequently consultations have been initiated to develop the programme post-2013. This presents an opportunity to develop more holistic RDP measures ... -
Optimal Design of Environmental-Friendly Hybrid Power Generation System
(Springer Nature, 2021-04-30)Combination of both renewable and fuel-based generation systems is an advantageous approach to develop off-grid distributed power plants. This approach requires evaluation of the techno-economic potential of each source ... -
Optimal energy efficiency in cell-free massive MIMO systems: A stochastic geometry approach
(Institute of Electrical and Electronics Engineers (IEEE), 2020-10-08)The increasing demand for green wireless communications and the benefits of the promising cell-free (CF) massive multiple-input-multiple-output (mMIMO) systems towards their optimal energy efficiency (EE) are the focal ... -
Optimal Fractional-Order PI Control Design for a Variable Speed PMSG-Based Wind Turbine
(2021-12-29)This paper focusses on the design of optimal control strategies for a variable-speed wind energy system based on Permanent Magnet Synchronous Generator (PMSG). The fractional order PI controller, denoted PIλ, is an extension ... -
Optimal healthcare delivery to care homes in the UK: a realist evaluation of what supports effective working to improve healthcare outcomes
(2018-07-01)Introduction: care home residents have high healthcare needs not fully met by prevailing healthcare models. This study explored how healthcare configuration influences resource use. Methods: a realist evaluation using ... -
An optimal inventory pricing and ordering strategy subject to stock and price dependent demand
(2021-11-23)This article considers the deterministic optimalcontrol problem of profit maximization for inventory replenishedat a variable rate and depleted by demand which is assumed tovary with price and stock availability. Optimal ... -
Optimal metallicity diagnostics for MUSE observations of low-z galaxies
(2024-01-01)The relatively red wavelength range (4800-9300 Å) of the VLT Multi Unit Spectroscopic Explorer (MUSE) limits which metallicity diagnostics can be used; in particular excluding those requiring the []λλ3726,29 doublet. We ... -
Optimal Modeled Six-Phase Space Vector Pulse Width Modulation Method for Stator Voltage Harmonic Suppression
(2018-09-29)Dual Y shift 30 six-phase motors are expected to be extensively applied in high-power yet energy-effective fields, and a harmonic-suppressing control strategy plays a vital role in extending their prominent features of low ... -
Optimal NHS service delivery to care homes: a realist evaluation of the features and mechanisms that support effective working for the continuing care of older people in residential settings
(2017-11-01)The OPTIMAL study argued that it is probable that there are key activities within different models of health-care provision that are important for residents’ health care. Objectives: To understand ‘what works, for whom, ... -
Optimal noise in spiking neural networks for the detection of chemicals by simulated agents
(MIT Press, 2008)We created a spiking neural controller for an agent that could use two different types of information encoding strategies depending on the level of chemical concentration present in the environment. The first goal of this ... -
Optimal Quality-of-Service Scheduling for Energy-Harvesting Powered Wireless Communications
(2016-01-19)In this paper, a new dynamic string tautening algorithm is proposed to generate the most energy-efficient off-line schedule for delay-limited traffic of transmitters with non-negligible circuit power. The algorithm is based ... -
Optimal tests to minimise bleeding and ischaemic complications in patients on extracorporeal membrane oxygenation
(2021-05-13)Patients supported with extracorporeal membrane oxygenation (ECMO) experience a very high frequency of bleeding and ischaemic complications, including stroke and systemic embolism. These patients require systemic ... -
Optimal treatment for obsessive compulsive disorder : A randomized controlled feasibility study of the clinical-effectiveness and cost-effectiveness of cognitive-behavioural therapy, selective serotonin reuptake inhibitors and their combination in the management of obsessive compulsive disorder
(2018-11-01)Established treatments for obsessive compulsive disorder (OCD) include cognitive behaviour therapy (CBT) and selective serotonin reuptake inhibitor (SSRI) medication. Combined treatment may outperform monotherapy, but few ... -
