Optical Spectropolarimetry of Broad Line Active Galaxies
(Astronomical Society of the Pacific, 1999)We present new optical spectropolarimetry of two bright type 1 AGNs. The observations are part of a project on broad line active galaxies in which, through data analysis and modelling, we aim to identify the polarization ... -
Optical spectroscopy of the candidate luminous white dwarf in the young Large Magellanic Cloud cluster NGC 1818
(1999)An optical spectrum of the Elson et al. (1998) candidate luminous white dwarf in the young LMC cluster NGC1818 shows conclusively that it is not a degenerate star. A model atmosphere fit gives Teff 31,500K and log g 4.4, ... -
Optical waveguides by diffusion in II-VI compounds
(1972)Planar optical waveguides have been made by sealed ampoule diffusion of Cd and Se into ZnS and Cd into ZnSe. Three-dimensional diffused guides of Cd-diffused ZnSe have been made by using a masking layer of evaporated ... -
The optically unbiased GRB host (tough) survey. III : Redshift distribution
(2012-06-10)We present 10 new gamma-ray burst (GRB) redshifts and another five redshift limits based on host galaxy spectroscopy obtained as part of a large program conducted at the Very Large Telescope (VLT). The redshifts span the ... -
Optimal analog wavelet bases construction using hybrid optimization algorithm
(2016-12-01)An approach for the construction of optimal analog wavelet bases is presented. First, the definition of an analog wavelet is given. Based on the definition and the least-squares error criterion, a general framework for ... -
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 Cooperative Spectrum Sensing for Cognitive Radio
(2016-09-08)The rapid increasing interest in wireless communication has led to the continuous development of wireless devices and technologies. The modern convergence and interoperability of wireless technologies has further increased ... -
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 ...
