2D and 3D soil moisture imaging using a sensor-based platform moving inside a subsurface network of pipes
(2013)In this study a prototype sensor-based platform moving inside a subsurface network of pipes with the task of monitoring the soil moisture content is presented. It comprises of a mobile platform, a modified commercial soil ... -
Accurate modeling of the cyclic response of structural components constructed of steel with yield plateau
(2012)A time-independent constitutive model for structural steels with a yield plateau is presented. The model is based on the basic principles of time-independent plasticity. The model couples the nonlinear kinematic hardening ... -
Air temperature regime in a forced ventilated greenhouse with rose crop
(2005)The use of forced ventilation for greenhouse cooling and air humidity regulation purposes has been expanded around Mediterranean area. The aim of the present study was the experimental investigation of the variables, as ... -
Application of the Sebs Water Balance Model in Estimating Daily Evapotranspiration and Evaporative Fraction from Remote Sensing Data Over the Nile Delta
(2011)Estimation of evapotranspiration is always a major component in water resources management. The reliable estimation of daily evapotranspiration supports decision makers to review the current land use practices in terms of ... -
Assessment and Modelling of Groundwater Quality Data by Environmetric Methods in the Context of Public Health
(2010)Various chemometric methods were used to analyze and model potable water quality data. Twenty water quality parameters were measured at 164 different sites in three representative areas (low land, semi-mountainous, 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 ... -
An assessment of two fundamental flat triangular shell elements with drilling rotations
(2000)An approach for adding drilling rotations to the constant strain triangle, such that the added rotation stiffness contributes a minimum to the strain energy of the triangle is presented. The element is combined with a ... -
Axial compression capacity of welded-slip pipeline joints
(2007)Using advanced numerical tools, which account for the cold-expansion manufacturing process, the axial capacity of welded slip pipeline joints under compressive loading is investigated. The numerical results are in good ... -
Behavior and Design of Corner Joints under Opening Bending Moment
(2014)The results of an experimental program concerning the influence of reinforcement detailing on the behavior of corners subjected to opening moment are presented. The motive for this work was the damage observed in an actual ... -
Behavior and ductility of reinforced concrete short columns using global truss model
(2006)The main results of an experimental program on eight full-scale reinforced concrete short columns are presented. The specimens were subjected to compression and cyclic reversed uniaxial shear displacements. The parameters ... -
Behaviour of short columns subjected to cyclic shear displacements: Experimental results
(2007)In this paper we present the results of an experimental program on eight reinforced concrete columns subjected to constant axial load and reversed statically imposed displacements. The loading conditions simulated those ... -
Bending resistance of composite slabs made with thin-walled steel sheeting with indentations or embossments
(2008)The paper studies the behaviour of thin-walled steel sheeting with embossments. The study aims to determine the contribution of the embossed areas of the steel sheeting to the total strength in pure tension and in pure ... -
Cluster Modeling of Driving Behavior Under Fatigue
(2014)A road safety campaign, as one of the measures used to influence road user behavior to follow the driving regulations and to safeguard safety on the road network, may contribute to the reduction of the number of people ... -
Comparison of Magnitude of Actions on Track in High-Speed and Heavy-Haul Railroads Influence of Resilient Fastenings
(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 ... -
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 ... -
Component mode synthesis techniques for finite element model updating
(2013)Deterministic and Bayesian finite element (FE) model updating techniques are computationally very demanding operations due to the large number of FE model re-analyses required. Component mode synthesis techniques are ... -
Constitutive Model for Cyclic Response of Structural Steels with Yield Plateau
(2011)A rate-independent cyclic plasticity model for structural steels with a yield plateau is proposed. The model couples nonlinear kinematic hardening with a memory surface in the plastic strain space, to account for the ... -
A constrained multi-agent system compensating for self-lucrative behaviours in water resource sharing
(2012)This paper presents the development of a multi-agent model for simulating realistic water-sharing scenarios and a means of studying and assessing an ecosystem's viability by taking under consideration environmental and ... -
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 ...
