Adaptive GLR Change Detector for Increasing Reliability of Vessel Performance System
(2019)In this paper a new adaptive GLR (generalized likelihood ratio) detector which is able to detect the stable periods of the operation of a vessel has been presented. To assess the performance of a vessel, the stable periods ... -
Aerodynamic shape optimization for minimum robust drag and lift reliability constraint
(2016)A methodology for shape optimization of aerodynamic bodies under uncertainties is presented. Flow-related and geometrical uncertainties are considered and quantified by probability distribution functions. The optimal shape ... -
Assessment of operation management for beer packaging line based on field failure data: A case study
(2010)Reliability analysis for packaging of beer production over a period of 9-month was carried out. The most important failure modes were identified and the descriptive statistics at failure and machine level were calculated. ... -
Calibration and signal interpretation for single and multiple hot-wire/hot-film probes
(1996)The use of single and multiple hot-wire/hot-film probes for subsonic flows is discussed with emphasis on the digital methods and procedures. An account is given of the major factors which influence the reliability of ... -
Coordinated broadcast-based request-reply and group management for tightly-coupled wireless systems
(2016)As the domain of cyber-physical systems continues to grow, an increasing number of tightly-coupled distributed applications will be implemented on top of wireless networking technologies. Some of these applications, including ... -
Day ahead energy market and Reliability Unit Commitment: An integrated approach
(2014)The restructured electricity markets typically involve a Day-Ahead Market (DAM), which clears bid-in demand that may be generally different (lower) than the demand forecast. This difference gives rise to reliability concerns ... -
Efficient techniques for bayesian inverse modeling of large-order computational models
(2013)Bayesian tools for inverse modeling are based on asymptotic approximations and Stochastic Simulation Algorithms (SSA). Such tools require a number of moderate to large number of system re-analyses. For large-order numerical ... -
Estimation of the prediction error correlation model in bayesian model updating
(2013)In Bayesian model updating, probability density functions of model parameters are updated accounting both for the information contained in the data and for uncertainties present in the measurements and model predictions, ... -
Goal orientation and participation motivation in tennis young players
(2013)Motivation is during the last decades at the center of scientific interest both in physical education and sport. The purpose of the study was to assess the construct validity, the reliability and the correlation between ... -
Market design for the simultaneous optimization of the Day-Ahead market and the reliability unit commitment applications
(2013)The design of restructured electricity markets requires a mechanism to ensure that differences between the bid-in demand that clears in the Day-Ahead Market (DAM) and the ISO's demand forecast do not compromise reliability ... -
Model-reduction techniques for reliability-based design problems of complex structural systems
(2016)This work presents a strategy for dealing with reliability-based design problems of a class of linear and nonlinear finite element models under stochastic excitation. In general, the solution of this class of problems is ... -
Motivation of 10-12 years old Cypriot students toward sports participation
(2011)The purpose of this study was to examine the reliability and validity of the Greek version of the Participation Motivation Questionnaire (PMQ) on Cypriot students. The sample consisted of 152 children aged 10-12 years old, ... -
Multi-Sensor Data Fusion for the Vessel Trim Analyzer and Optimization Platform
(2019)The purpose of this paper is to describe a platform and the multi-sensor Data Fusion., that is used to analyze the power consumed regarding the Vessel's trim during past Voyages and to provide decision making support about ... -
Parametric analysis of axially loaded RHS gap K-joints by means of 2-D and 3-D F.E. models
(2003)In the present paper the behaviour of steel structural RHS gap K-joints under static loading is studied by applying the Finite Element Method. The analysis is performed by the development of both 2-D and 3-D models of gap ... -
