Comparison of two types of synchronization of external-cavity semiconductor lasers
(2002-01-01)
Article
Accés obertWe study numerically the synchronization of external-cavity semiconductor lasers in a master–slave configuration, based on a Lang–Kobayashi-type model. Depending on the feedback and coupling strengths, the slave laser ... -
Comparison of two voltage control strategies for a wind power plant
(IEEE, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialLarger percentages of wind power penetration translate to more demanding requirements from grid codes. Recently, voltage support at the point of connection has been introduced by several grid codes from around the world, ... -
Comparison of unstructured grid and overset grid approaches for flow computations around a ship with an energy-saving duct
(CIMNE, 2015)
Text en actes de congrés
Accés obertTwo approaches for CFD simulations for a complex geometry of a ship with an energy-saving duct are compared. One method is an unstructured grid method in which the single block grid can cover the whole ... -
Comparison of upper airway respiratory resistance measurements with the esophageal pressure/airflow relationship during sleep
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialMeasurement of upper airway resistance is of interest in sleep disordered breathing to estimate upper airway patency. Resistance is calculated with the airflow and respiratory effort signals. However, there is no consensus ... -
Comparison of various approaches to design wind-PV rural electrification projects in remote areas of developing countries
(2018-01-01)
Article
Accés obertNowadays, around 1.1 billion people in rural and remote areas of developing countries remain without electricity. Stand-alone projects that combine the wind and photovoltaic generation technologies as well as microgrids ... -
Comparison of various coupling methods for 1D diffusion equations with a analytical solution of two phase Stefan problem
(CIMNE, 2019)
Text en actes de congrés
Accés obertWe implemented loose and tight coupling methods to understand thermal diffusion between ocean and ice by means of a simplified one-dimensional model set-up proposed by Stefan. A Stefan problem is a prototypical ... -
Comparison of various guidance strategies to achieve time constraints in optimal descents
(2019-01-01)
Article
Accés obertContinuous Descent Operations (CDOs) have been subject of extensive research in the last decades. Even if proving successful in reducing the environmental impact [1], such operations suffer from a well-known drawback: the ... -
Comparison of video-based methods for respiration rhythm measurement
(2019-05-01)
Article
Accés obertThe aim of this work is to characterize the di erences in the respiratory rhythm obtained through three video based methods by comparing the obtained respiratory signals with the one obtained with the gold standard method ... -
Comparison of Virtual Networks Solutions for Community Clouds

Projecte/Treball Final de Carrera
Accés obert
Realitzat a/amb: Kungliga Tekniska högskolanIn this thesis we will study, compare and analyze the possibility of using Tinc, IPOP or SDN-based solutions such as OpenFlow to establish a VPN for community clouds. -
Comparison of visual and optical quality of monofocal versus multifocal intraocular lenses
(2019-02-10)
Article
Accés obert -
Comparison of visual performance between two aspheric monofocal intraocular lens models
(Taylor & Francis, 2021-12-07)
Article
Accés obertClinical relevance It is important to distinguish between visual acuity, optical quality and quality of vision when outcomes obtained with intraocular lenses are evaluated. These parameters, that includeobjective and ... -
Comparison of wear models using a lagrangian approach
(CIMNE, 2015)
Text en actes de congrés
Accés obertAbrasive wear of hydraulic machines is commonly simulated with grid based methods. In this work we present a mesh-free approach for modeling abrasive wear. The transport fluid is modeled with the Smoothed Particle Hydrodynamics ... -
Comparison of weathering variables on chrome-tanned and wet-white leather ageing
