Automatic feature selection and weighting for the formation of homogeneous groups for regional IDF estimation
(Elsevier, 2019-08)The intensity-duration frequency (IDF) curve has been used as an effective tool to quantify the risk associated with the impact of extreme rainfall on civil infrastructure. However, recent changes in the rainfall climatology ... -
Changes in flood events inferred from centennial length streamflow data records
(Elsevier, 2018-11-01)This research examines ways that climate change may alter the risk of flooding in cold regions focusing on changes in the flood regimes and changes and shifts in the dominant flood generating processes at 27 natural ... -
Classification of Construction Projects
(World Academy of Science, 2015-07-01)In order to address construction project requirements and specifications, scholars and practitioners need to establish taxonomy according to a scheme that best fits their need. While existing characterization methods are ... -
Confirming the need for virus disinfection in municipal subsurface drinking water supplies
(Elsevier, 2019-06)Enteric viruses pose the greatest acute human health risks associated with subsurface drinking water supplies, yet quantitative risk assessment tools have rarely been used to develop health-based targets for virus treatment ... -
Development of a global road safety performance function using deep neural networks
(Elsevier, 2017-08-01)This paper explores the idea of applying a machine learning approach to develop a global road safety performance function (SFP) that can be used to predict the expected crash frequencies of different highways from different ... -
Effect of quality control parameter variations on the fatigue performance of aluminum friction stir welded joints
(Elsevier, 2019-01-01)This paper describes fatigue tests performed on 6061-T651 and 5083-H321 aluminum friction stir welded joints with dimensions and loading conditions typical for structural applications. Butt and lap joint details with various ... -
Effects of beam axial deformations on storey-based critical gravity loads in tension-only semi-braced steel frames
(Elsevier, 2021-04-01)If the beams in a structural frame are not connected to slabs or other rigid diaphragms, the beams will axially deform when the frame is subjected to lateral loads, reducing the critical loads and increasing local deflections ... -
Effects of column imperfections on capacity of steel frames in variable loading
(Journal of Constructional Steel Research, 2019-11-15)The presence of column initial imperfections in a steel frame can increase deflections and decrease its load carrying capacity. A method is proposed for evaluating the lateral stiffness, inter-storey displacement and ... -
Efficient treatment of climate data uncertainty in ensemble Kalman filter (EnKF) based on an existing historical climate ensemble dataset
(Elsevier, 2019-01)Successful data assimilation depends on the accurate estimation of forcing data uncertainty. Forcing data uncertainty is typically estimated based on statistical error models. In practice, the hyper-parameters of statistical ... -
Enriched mixed finite element models for dynamic analysis of continuous and fractured porous media
(Elsevier, 2019-01-01)Enriched Finite Element Models are presented to more accurately investigate the transient and wave propagation responses of continuous and fractured porous media based on mixture theory. Firstly, the Generalized Finite ... -
Estimates of gridded relative changes in 24-h extreme rainfall intensities based on pooled frequency analysis
(Elsevier, 2019-10)The potential effect of climate change needs to be considered in urban infrastructure design and risk assessment to improve reliability. The present study proposes a methodology for obtaining grid-scale relative changes ... -
Event-based model calibration approaches for selecting representative distributed parameters in semi-urban watersheds
(Elsevier, 2018-08-01)The objective of this study is to propose an event-based calibration approach for selecting representative semi-distributed hydrologic model parameters and to enhance peak flow prediction at multiple sites of a semi-urban ... -
A hybrid Bayesian network model for predicting delays in train operations
(Elsevier, 2019-01)We present a Bayesian network-(BN) based train delay prediction model to tackle the complexity and dependency nature of train operations. Three different BN schemes, namely, heuristic hill-climbing, primitive linear and ... -
In-situ chemical oxidation of chlorendic acid by persulfate: Elucidation of the roles of adsorption and oxidation on chlorendic acid removal
(Elsevier, 2019-10-15)The oxidation of chlorendic acid (CA), a polychlorinated recalcitrant contaminant, by heat-, mineral-, and base-activated persulfate was investigated. In pH 3–12 homogeneous (i.e., solid-free) solutions, CA was oxidized ... -
Modeling the Modal Shift towards a More Sustainable Transport by Stated Preference in Riyadh, Saudi Arabia
(MDPI, 2021-01-01)The need to gain a comprehensive understanding of road travelers’ choice of mode and their perceptions of using sustainable urban mobility modes have evolved to shape the form of future transport planning and policymaking. ... -
