Appraisal of road pavement evaluation methods
(2019)Road pavement evaluation methods are based either on simple index of a surface characteristic, such as International Roughness Index (IRI) for roughness, Rut Depth (RD) for rutting, Sideway Force Coefficient (SFC) for ... -
Direct numerical simulation of particle-laden turbulent channel flows with two- and four-way coupling effects: Budgets of Reynolds stress and streamwise enstrophy
(2016)The budgets of the Reynolds stress and streamwise enstrophy are evaluated through direct numerical simulations for the turbulent particle-laden flow in a vertical channel with momentum exchange between the two phases. The ... -
Direct numerical simulation of particle-laden turbulent channel flows with two- and four-way coupling effects: Models of terms in the Reynolds stress budgets
(2017)In the first part of this study (Dritselis 2016 Fluid Dyn. Res. 48 015507), the Reynolds stress budgets were evaluated through point-particle direct numerical simulations (pp-DNSs) for the particle-laden turbulent flow in ... -
A Distance Learning VR Technology Tool for Science Labs
(2022)Distance learning technology and online learning are here to stay. The pandemic crisis made that very clear but the increasing number of the students who are grown up as 'digital natives' and want to communicate and learn ... -
Distributed Estimation in Wireless Sensor Networks with an Interference Canceling Fusion Center
(2016)In this paper, we consider Distributed Estimation (DES) in a Wireless Sensor Network (WSN) and assume that the number of sensors in the WSN is larger than the available number of transmission slots. With classic DES, the ... -
Economic assessment of pavement maintenance and strengthening techniques in view of implementation cost
(2020)Road and pavement maintenance affect directly traffic safety and comfort. At the same time, maintenance treatments cause traffic discomfort and absorb valuable resources, thus, the choice of maintenance and rehabilitation ... -
The eLOD ontology: Modeling economic open data
(2016)For decades, valuable economic data was out of reach for most of the people. Gradually, public budgets and tenders are becoming openly available and global initiatives promote financial transparency and data innovation. ... -
Energy project portfolio selection and scheduling
(2022)In the present work, we formulated an integrated method in order to confront two problems regarding a project portfolio that contains energy projects and/or proposals for projects to be implemented in the future. More ... -
Exploiting Significance of Computations for Energy-Constrained Approximate Computing
(2016)Approximate execution is a viable technique for environments with energy constraints, provided that applications are given the mechanisms to produce outputs of the highest possible quality within the available energy budget. ... -
A heuristic approach for overlay content-caching network design in 5G wireless networks
(2016)With a wide variety of mobile applications and social networks, there is a growing demand for anytime, anywhere access to high quality video and other multimedia content. Fifth generation wireless networks are aiming to ... -
Load management of electric vehicles charging in new generation power markets based on fuzzy logic and the concept of virtual budget
(2019)The aim of the current study is the development and the evaluation of a fully automated controller based on fuzzy logic for the control of the charging time of Electric Vehicles (EVs) based on user's preferences and the ... -
A Measure Generator Tool for Sustainable Urban Mobility
(2021)The present paper details the development of a designated software that facilitates the selection of the appropriate measures to achieve high level sustainable urban mobility. The main objective of this tool is to combine ... -
A multi-periodic optimization modeling approach for the establishment of a bike sharing network: A case study of the City of Athens
(2014)This study introduces a novel mathematical formulation that addresses the strategic design of a bicycle sharing network. The developed pure integer linear program takes into consideration data such as the potential future ... -
A Mutliple Stakeholders' Software Requirements Prioritization Approach based on Intuitionistic Fuzzy Sets
(2022)Prioritization of requirements in a software project is a crucial activity for the project success. Taking into account the time and budget constraints imposed by the available project resources, it is often not possible ... -
On the statistical memory architecture exploration and optimization
(2015)The worsening of process variations and the consequent increased spreads in circuit performance and consumed power hinder the satisfaction of the targeted budgets and lead to yield loss. Corner based design and adoption ... -
Optimal sensor placement for parameter estimation and virtual sensing of strains on an offshore wind turbine considering sensor installation cost
(2022)This paper proposes an optimal sensor placement (OSP) framework for parameter estimation, virtual sensing, and condition monitoring using information theory. The framework uses a Bayesian OSP method combined with modal ... -
Optimal Trade-Off between Depth and Coverage for a Vertical UOWC Link
