Advancements of nanotechnologies in crop promotion and soil fertility: Benefits, life cycle assessment, and legislation policies
(2021)Increasing agricultural production has become one of the key components to bridge the gap between securing food resources and sustainable development goals (SDGs), namely, no poverty, zero hunger, preservation of natural ... -
Comparative Analysis of Methodologies for Calculating the Economic Life of Construction Equipment
(2020)The most profitable period of owning and operating a machine is during its economic life. To find the “sweet spot”, i.e. the time in the life cycle of the machine where owning and operating costs reach the minimum point, ... -
Comparison of magnitude of actions on track in high-speed and heavy-haul railroads
(2012)In modern high-speed railways the necessity for achieving low life-cycle costs has led to a well-compacted-almost undeflected-substructure. Applications of excellent quality substructure are encountered in the French network ... -
THE ECONOMIC AND ENVIRONMENTAL IMPACTS OF CASTOR SUPPLY CHAIN: A GREEK CASE STUDY
(2022)Castor is a candidate crop that grows in marginal lands in the Mediterranean area. The objective of the present study was to evaluate the economic and environmental impacts under the Mediterranean climate and farming ... -
Environmental assessment of precision farming techniques in a pear orchard
(2017)Pears require a substantial number of inputs for satisfactory yield and quality. High inputs increase costs, reducecompetitiveness and induce environmental problems. In thecurrent study the environmental profile of a pear ... -
Fast Bayesian structural damage localization and quantification using high fidelity FE models and CMS techniques
(2012)Bayesian estimators are proposed for damage identification (localization and quantification) of civil infrastructure using vibration measurements. The actual damage occurring in the structure is predicted by Bayesian model ... -
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 ... -
Influence of rail pad stiffness on track stressing, life-cycle and noise emission
(2010)In this paper the results for the influence of the rail pad stiffness on the Railway Track stressing and its Life-Cycle is presented, as derived from a research program performed in Greece due to the appearance of extended ... -
Influence of the prediction error correlation model on Bayesian FE model updating results
(2012)Bayesian finite element (FE) model updating is a probabilistic method for uncertainty quantification in FE model updating, where the well-known Bayes' theorem is used to update probability density functions of model ... -
An information theoretic framework for optimal experimental design
(2017)An information theoretic framework for optimal experimental design is presented. The objective function is rooted in information theory, and is the expected Kullback-Leibler divergence between the prior and posterior pdf ... -
Input-state-parameter estimation of structural systems from limited output information
(2019)A successive Bayesian filtering framework for addressing the joint input-state-parameter estimation problem is proposed in this study. Following the notion of analytical, rather than hardware redundancy, the envisaged ... -
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 ... -
Machine learning product key performance indicators and alignment to model evaluation
(2021)Machine Learning has seen amazing progress the past years with increasing commercial use from industries across the business spectrum. Businesses strive for alignment of vision and mission statement to the actual products ... -
On the potential of dynamic sub-structuring methods for model updating
(2019)While purely data-driven assessment is feasible for the first levels of the Structural Health Monitoring (SHM) process, namely damage detection and arguably damage localization, this does not hold true for more advanced ... -
Output-only fatigue prediction of uncertain steel structures
(2016)A fatigue estimation framework for steel structures is proposed in this study, under realistic assump-tions on the sensor network capacity and under the premise of uncertainty in the structural information available ... -
Prediction of fatigue damage accumulation in metallic structures by the estimation of strains from operational vibrations
(2012)This work deals with the problem of estimating damage accumulation due to fatigue in the entire body of a metallic structure using operational vibration measurements collected from a limited number of sensors installed on ... -
Product R & D, process R & D and market dynamics: A simulation study
(2002)This paper presents a simulation study carried out for the investigation of the dynamics of the combined development-production-selling system of a firm. Different product line management strategies were evaluated with ... -
Resilience assessment of tunnels: Framework and application for tunnels in alluvial deposits exposed to seismic hazard
(2022)Transport infrastructure is the backbone of the economy and society, while at the same time is exposed to multiple hazards. Previous natural disasters, including earthquakes, had a significant impact on transport networks ... -
SLICES, a scientific instrument for the networking community
(2022)A science is defined by a set of encyclopedic knowledge related to facts or phenomena following rules or evidenced by experimentally-driven observations. Computer Science and in particular computer networks is a relatively ... -
Success stories from consumer technology-helping and saving lives
