Analysis of heat affected zone in welded aluminum alloys using inverse and direct modeling
(2008)The concept of constructing parameter spaces for process control and the prediction of properties within the heat affected zone (HAZ) of welds using inverse modeling is examined. These parameter spaces can be, in principle, ... -
Climatic impacts on the runoff generation processes in British Columbia, Canada
(2002)The potential impact of future climate change on runoff generation processes in two southern British Columbia catchments was explored using the Canadian Centre for Climate Modelling Analysis General Circulation Model ... -
Computational kinetics simulation of the dissolution and coarsening in the HAZ during laser welding of 6061-T6 Al-alloy
(2007)Laser beam welding (LBW) has become common practice in the production lines of several industrial sectors including the electronics, domestic appliances, and automotive industries. The advantages of LBW over conventional ... -
Effects of temper condition and corrosion on the fatigue performance of a laser-welded Al-Cu-Mg-Ag (2139) alloy
(2010)The effects of temper condition and corrosion on the fatigue behavior of a laser beam welded Al-Cu-Mg-Ag alloy (2139) have been investigated. Natural aging (T3 temper) and artificial aging (T8 temper) have been applied ... -
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 ... -
Hydroclimatic variability of regional droughts in Greece using the palmer moisture anomaly index
(2002)The hydroclimatic variability of droughts at a regional scale in the semiarid climate of Greece was examined in this paper. The moisture anomaly Z-index of the Palmer Drought Severity Index (PDSI) was employed for a ... -
Modelling of microsegregation and homogenization of 6061 extrudable Al-alloy
(2007)A simulation of the evolution of the as-cast microstructure during the homogenization heat treatment of A6061 aluminum alloy is presented. The microstructure is dendritic with phase and solute segregation. The alloy ... -
Nonstationary Frequency Analysis of Annual Maximum Rainfall Using Climate Covariates
(2015)The perception that hydrometeorological processes are non stationary on timescales that are applicable to extreme value analysis is recently well documented due to natural climate variability or human intervention. In this ... -
Phase fraction mapping in the as-cast microstructure of extrudable 6xxx aluminum alloys
(2014)The mapping of Mg2Si and beta-AlFeSi phase fractions in the as-cast microstructure of Al-Mg-Si-Fe-Mn (6xxx series) alloys has been performed over the useful composition range (0-1.2 mass%) of the principal alloying elements ... -
The role of SO42- surface distribution in arsenic removal by iron oxy-hydroxides
(2014)This study investigates the contribution of chemisorbed SO42- in improving arsenic removal properties of iron oxy-hydroxides through an ion-exchange mechanism. An analytical methodology was developed for the accurate ... -
Severity-duration-frequency analysis of droughts and wet periods in Greece
(2000)There is an escalation in the frequency and severity of extreme events due to a number of environmental and/or anthropogenic factors. Droughts and exceptionally wet periods are regional phenomena, which are considered as ...
