Flood frequency estimation by a derived distribution procedure
(2002)An event rainfall-runoff simulation procedure based on the method of derived distributions is proposed for the estimation of flood frequency for ungauged watersheds. The procedure uses a stochastic rainfall generation model ... -
Flood producing mechanisms identification in southern British Columbia, Canada
(2000)The causes of peak flows in two climatically different mountainous-forested basins of British Columbia have been identified. The U.B.C. watershed model was used to identify the causes of peak flows, since this model ... -
Forecasting of Remotely Sensed Daily Evapotranspiration Data Over Nile Delta Region, Egypt
(2013)Daily evapotranspiration is a major component in crops water consumption management plans. Consequently, forecasting of daily evapotranspiration is the keystone of any effective water resources management plans in fragile ... -
Framework for Monitoring and Assessing Performance Quality of Railway Network Infrastructure: Hellenic Railways Case Study
(2014)In accordance with European Policy, management, maintenance, upgrading, and repair of existing infrastructures play a very important role in their optimal use. Availability and access to information regarding the track-support ... -
Geoinformatic Intelligence Methodologies for Drought Spatiotemporal Variability in Greece
(2012)One of the most important hazards in terms of cost, frequency of occurrence and impact on humans is drought. Drought indices are estimations of precipitation shortage and water supply deficit. Satellite drought indices are ... -
Impact of building design and occupancy on office comfort and energy performance in different climates
(2014)The building sector has a significant share in a county's total greenhouse gas emissions, and as a reaction to the Kyoto commitment most countries are constantly adjusting building energy requirements in order to reduce ... -
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 ... -
Integrated Water Management Plans for the Restoration of Lake Koronia, Greece
(2007)Lake Koronia is a very important ecosystem of Greece which is almost vanishing because of non sustainable water management practice in the region. The ongoing unsystematic economic growth of the area has resulted to water ... -
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 ... -
Load Path Effects in Circular Steel Columns under Bidirectional Lateral Cyclic Loading
(2015)Rigorous numerical analyses are conducted to study the effects of bidirectional lateral cyclic loading on the hysteretic response of stocky circular thin-walled steel columns. Four unidirectional and eight bidirectional ... -
Loads on Track, Ballast Fouling, and Life Cycle under Dynamic Loading in Railways
(2010)In this paper a new method is presented for the estimation of actions on sleepers and the pressures that develop under the seating surface of the sleeper and are transmitted on the ballast. Results from laboratory tests ... -
A mathematical approach to define threshold values of pavement characteristics
(2014)Transportation authorities managing road networks have to define threshold values of acceptance for pavement surface characteristics. This procedure is either based on relevant experience or drawn from a combination of ... -
Mathematical Macromodeling of Infilled Frames: State of the Art
(2011)The primary objective of this paper is to present a general review of the different macromodels used for the analysis of infilled frames. A number of distinct approaches in the field of analysis of infilled frames since ... -
MODAL DYNAMICS APPROXIMATIONS OF CANTILEVERS UNDER PARTIAL FOLLOWER LOAD
(2010)Presented herein is a modified Galerkin discretization procedure for determining the qualitative dynamic behavior of elastic cantilevers with internal damping under partial follower step loading at their tips. For this ... -
A modeling system for the evaluation of water resources management strategies in thessaly, greece
(2007)A modeling system was developed to evaluate the sustainability of water resources management strategies in the two major basins of Thessaly Region in Greece, namely the Pinios River and the Lake Karla basins. The intense ... -
Multi-Criteria Analysis Framework for Potential Flood Prone Areas Mapping
(2015)A fundamental component of the European natural disaster management policy is the detection of potential flood-prone areas, which is directly connected to the European Directive (2007/60). This study presents a framework ... -
Multi-objective framework for structural model identification
(2005)Structural identification based on measured dynamic data is formulated in a multi-objective context that allows the simultaneous minimization of the various objectives related to the fit between measured and model predicted ... -
A Multiobjective Model for Maximizing Fleet Availability under the Presence of Flight and Maintenance Requirements
(2009)Every aircraft, military or civilian, must be grounded for maintenance after it has completed a certain number of flight hours since its last maintenance check. In this paper, we address the problem of deciding which ...
