Mapping ephemeral stream networks in desert environments using very-high-spatial-resolution multispectral remote sensing
(Elsevier Inc., 2016)Mapping of ephemeral streams in desert environments is crucial to understanding the impacts to hydrologic and ecosystem functions caused by land-use changes. Available mapping methods at the watershed-scale typically ... -
Meshfree analysis with the aid of NURBS boundary.
(Springer Verlag, 2016-09)We present a meshfree analysis framework to integrate the geometric exactness of non-uniform rational B-splines (NURBS)-based isogeometric analysis (IGA) (Hughes et al., Comput Methods Appl Mech Eng 194:4135–4195, 2005) ... -
Modeling flight delay propagation: A new analytical-econometric approach.
(Elsevier, 2016-11)Flight delay presents a widespread phenomenon in the air transportation system, costing billions of dollars every year. Some delay originating from an upstream flight spreads to downstream flights. This phenomenon is defined ... -
Modeling interdependencies between vehicle transaction, residential relocation and job change
(Springer Verlag, 2011-07-14)This paper introduces a vehicle transaction timing model which is conditional on household residential and job relocation timings. Further, the household residential location and members’ job relocation timing decisions ... -
Negative extensibility metamaterials: Occurrence and design-space topology
(American Physical Society, 2017-08)A negative extensibility material structure pulls back and contracts when the external tensile load reaches a certain critical level. In this paper, we reveal basic mathematical features of the nonlinear strain energy ... -
Network-Based and Binless Frequency Analyses
(PLoS One, 2015-11-03)We introduce and develop a new network-based and binless methodology to perform frequency analyses and produce histograms. In contrast with traditional frequency analysis techniques that use fixed intervals to bin values, ... -
Network-based and binless frequency analyses.
(Public Library of Science, 2015-11-03)We introduce and develop a new network-based and binless methodology to perform frequency analyses and produce histograms. In contrast with traditional frequency analysis techniques that use fixed intervals to bin values, ... -
A Network-based Frequency Analysis of Inclusive Wealth to Track Sustainable Development in World Countries
(Elsevier, 2018-07-15)Using human (HC), natural (NC), and produced (PC) capital from Inclusive Wealth as representatives of the triple bottom line of sustainability and utilizing elements of network science, we introduce a Network-based Frequency ... -
Nonadiabatic chemical-to-electrical energy conversion in heterojunction nanostructures
(American Physical Society, 2010-05-15)Nonadiabatic energy dissipation by electron subsystem of nanostructured solids unveil interesting opportunities for the solid-state energy conversion and sensor applications. We found that planar Pt/GaP and Pd/GaP Schottky ... -
A Nonthermal Chemicurrent Effect of Hydrogen Adsorption on Pt/SiC Planar Nanostructures at Normal Ambient Conditions
(Elsevier, 2012-11)Reaction induced currents in planar metal/semiconductor nanostructures can provide a direct insight into underlying charge transfer processes involved in chemical energy dissipation at solid surfaces. This letter provides ... -
Novel Leak Localization in Pressurized Pipeline Networks using Acoustic Emission and Geometric Connectivity
(Elsevier, 2012-04)Time dependent aging and instantaneous threats can cause the initiation of damage in the buried and on-ground pipelines. Damage may propagate all through the structural thickness and cause leaking. The leakage detection ... -
Numerical Investigation of Statistical Variation of Concrete Material Properties between Scales
(Wiley, 2017-06-07)Concrete is typically treated as a homogeneous material at the continuum scale. However, the randomness in micro-structures has profound influence on its mechanical behavior. In this work, the relationship of the statistical ... -
Numerical simulation of mixed mode (I and II) fracture behavior of pre-cracked rock using the strong discontinuity approach.
(Elsevier Inc., 2016-02-10)The existence of macroscopic flaws in geomaterial structures profoundly influences their load-carrying capacity and failure patterns. This paper is devoted to the numerical investigation of mixed–mode fracture propagation ... -
