Response matrix minimization used in groundwater management with mathematical programming: A case study in a transboundary aquifer in Northern Greece
(2006)
Groundwater has always been considered to be a readily available source of water for domestic, agricultural and industrial use. The last decades, the lack of policymaking for the utilization of groundwater, has led to ...
Comparison of quadratic and non-linear programming (QP and NLP) optimization models in groundwater management
(2004)
This project is concerned with the comparison of two algorithms used in groundwater management models based on Quadratic Programming (QP) and Non-linear Programming (NLP) models,. A quadratic objective function is used and ...
Assessment of seismic design procedures based on the total cost
(2006)
The assessment of seismic design codes has become the subject of intensive research work which revealed several weak points of the codes that originated from the limitations in predicting with acceptable precision the ...
A linear model for the continuous network design problem
(2006)
This article is concerned with the continuous network design problem on traffic networks, assuming system optimum traffic flow conditions and time-dependent demand. A linear programming formulation is introduced based on ...
Impact of climate change on comfort and energy performance in offices
(2012)
This paper investigates the impact of a climate change scenario on comfort and energy performance in offices, in relation to the influence of building design and occupants. It focuses on a typical cellular office room in ...
Fatigue predictions in entire body of metallic structures from a limited number of vibration sensors using Kalman filtering
(2011)
A methodology is proposed for estimating damage accumulation due to fatigue in the entire body of a metallic structure using output-only vibration measurements from a sensor network installed at a limited number of structural ...
Variability of updated finite element models and their predictions consistent with vibration measurements
(2012)
A case study on a small-scale laboratory vehicle frame is used to investigate the variability of the updated finite element (FE) models that arises from model and measurement errors and demonstrate the effect of this ...
Corrosion of exposed rebars, associated mechanical degradation and correlation with accelerated corrosion tests
(2011)
In a large number of steel reinforced concrete buildings in Greece, spalling of the cement has left the steel reinforcement (rebars) exposed to the atmosphere. This has led to corrosion of the exposed rebars, especially ...
Pipe Networks Risk Assessment Based on Survival Analysis
(2011)
Integrated management of pipe networks should include methods for monitoring, repairing and replacing deteriorating components (usually pipes), but also methods and everyday operating practices towards a proactive risk ...
A New Analytical Model to Predict the Hydraulic Conductivity of Unsaturated Soils
(1996)
A new analytical model is presented for the prediction of hydraulic conductivity. The new model is based on the Brutsaert characteristic curve psi(theta) and the Mualem integral relation. It is presented by a series expansion ...
