An Automated Method for Quality Control in MRI Systems: Methods and Considerations
(2020)Objective: The purpose of this study was to develop an automated method for performing quality control (QC) tests in magnetic resonance imaging (MRI) systems, investigate the effect of different definitions of QC parameters ... -
Characterization of the allowable perturbations for disturbance rejection and data sensitivity
(1996)In this paper the problem of disturbance rejection and data sensitivity is studied for the case of linear time invariant systems. Using a proportional state feedback law, the necessary and sufficient conditions for the ... -
A delay-resilient and quality-aware mechanism over incomplete contextual data streams
(2016)We study the case of scheduling a Contextual Information Process (CIP) over incomplete multivariate contextual data streams coming from sensing devices in Internet of Things (IoT) environments. CIPs like data fusion, concept ... -
Dynamic cross-layer association in 802.11-based mesh networks
(2007)In IEEE 802.11-based wireless mesh networks a user is associated with an access point (AP) in order to communicate and be part of the overall network. The association mechanism specified by the IEEE 802.11 standard does ... -
Dynamic modelling of an ultra high temperature PCM with combined heat and electricity production for application at residential buildings
(2020)The present study investigates the thermal performance of an ultra-high temperature (> 1000 °C) latent heat thermal energy storage system that utilizes silicon as a phase-change (PCM) material. Application of this system ... -
The effect of railway local irregularities on ground vibration
(2015)The environmental effects of ground-borne vibrations generated due to localised railway defects is a growing concern in urban areas. Frequency domain modelling approaches are well suited for predicting vibration levels on ... -
The effect of sorptivity on cumulative infiltration
(2021)Hydraulic parameters of the soil play a considerable role in the hydrological cycle, irrigation planning, drainage, groundwater recharge, and water resources management. One of the most important hydraulic parameters of ... -
Efficacy of n-3 fatty acid supplementation on rheumatoid arthritis’ disease activity indicators: a systematic review and meta-analysis of randomized placebo-controlled trials
(2022)Theoretical evidence and previous studies suggest that oralnutrient supplementation (ONS) with n-3 fatty acids for rheumatoid arthritis (RA) has the potential to lower disease activity indicators and non-steroidal ... -
Estimation of models for cumulative infiltration of soil using machine learning methods
(2021)Knowledge of cumulative infiltration of soil is necessary for irrigation, surface flow, groundwater recharge and many other hydrological processes. In the present study, the Support Vector Machine (SVM), artificial neural ... -
Estimation of the recharging rate of groundwater using random forest technique
(2020)Accurate knowledge of the recharging rate is essential for several groundwater-related studies and projects mainly in the water scarcity regions. In this study, a comparison between different methods of soft computing-based ... -
FEA of Drug-Eluting Stents and Sensitivity Analysis of a Continuum Damage Model for the Degradation of PLGA Coating
(2021)Drug-Eluting Stents (DES) are commonly used in coronary angioplasty operations as a solution against artery stenosis and restenosis. Computational Bioengineering allows for the in-silico analysis of their performance. The ... -
Gas-surface interaction in rarefied gas flows through long capillaries via the linearized Boltzmann equation with various boundary conditions
(2022)Reliable gas–surface interaction modeling is of major importance in consistent simulation of rarefied gas flows with applications in vacuum technology and micro-electromechanical systems. The effectiveness of the most ... -
Greek wholesale electricity market: Forthcoming market changes and bid/cost recovery
(2012)The Greek wholesale electricity market is based on a day-ahead unit commitment market clearing and generation dispatch formulation with co-optimization of energy and reserves without the participation of transmission. An ... -
Impact of emissions cost on the mid-term generation scheduling in the Greek Electricity Market
(2010)The EU Emissions Trading Scheme, Europe's main mechanism for implementing EU climate policy, is driving thermal electricity generation units to incorporate their emissions cost into their variable costs. In this paper, we ... -
Industry performance evaluation with the use of financial ratios: An application of bootstrapped DEA
(2012)In data envelopment analysis (DEA) context financial data/ratios have been used in order to produce a unified measure of performance metric. However, several scholars have indicated that the inclusion of financial ratios ... -
Lca-based environmental performance of olive cultivation in northwestern greece: from rainfed to irrigated through conventional and smart crop management practices
(2021)Olive cultivation is expanding rapidly in the northwestern part of Greece, under both rainfed and irrigated practices. Irrigation can result in larger yields and economic returns, but trade-offs in the water–energy–pollution ... -
