An examination of susceptibility to spear phishing cyber attacks in non-English speaking communities
(
Elsevier
, 2020 , Article)
PurposeSpear phishing is a fraudulent practice that targets specific and well-researched users in an organization to collect their credentials. Previous studies have addressed the underlying drivers that significantly ...
Phase-I monitoring of high-dimensional covariance matrix using an adaptive thresholding LASSO rule
(
Elsevier
, 2020 , Article)
High-dimensional variability monitoring and diagnosing is of great prominence for the quality improvement and cost reduction. Most of the existing control charts are mainly based on the assumption that the in-control ...
Experimental analysis of water evaporation losses in cooling towers using filters
(
Elsevier
, 2020 , Article)
Water evaporation losses in cooling towers account for considerable amount of fresh water consumption, which calls for proven and economically viable technologies to address this problem. The use of filters mounted on to ...
Turbulence modeling using Z-F, RSM, LES and WMLES for flow analysis in Z-Shape ducts
(
American Society of Mechanical Engineers (ASME)
, 2020 , Conference Paper)
Turbulent flow in Z-shape duct configuration is investigated and analyzed using Reynolds Stress Model (RSM), Large Eddy Simulation (LES), ζ-f Model, and Wall-Modeled Large Eddy Simulation (WMLES). The results are validated ...
Heat transfer measurements of Polyalpha-Olefin- boron nitride nanofluids for thermal management and lubrication applications
(
Elsevier
, 2020 , Article)
In this paper, the first study is reported combining Polyalpha-Olefin (PAO) oil with hexagonal Boron Nitride (hBN) to produce new class of nanofluids for heat transfer and lubrication applications. The heat transfer ...
Turbulence Modeling Using Z-F Model and RSM for Flow Analysis in Z-SHAPE Ducts
(
Wiley
, 2020 , Article)
Turbulent flow in Z-shape duct configuration is investigated using Reynolds stress model (RSM) and ζ-f model and compared to experimental results. Both RSM and ζ-f models are based on steady-state RANS solutions. The focus ...
Isobaric Expansion Engines Powered by Low-Grade Heat-Working Fluid Performance and Selection Database for Power and Thermomechanical Refrigeration
(
Wiley-VCH Verlag
, 2020 , Article)
A database is developed for the most suitable working fluids for Worthington-type and Bush-type isobaric engines based on their performances for a wide range of heat source temperature, from 40 to 300 °C, and operating ...
Large-eddy simulation of the flow in Z-Shape duct
(
Cogent OA
, 2020 , Article)
A numerical study is conducted of the transient flow in a z-shape three-dimensional duct using large-eddy simulation (LES) with dynamic eddy viscosity subgrid-scale (SGS) model with a fully structured grid system. The ...
Students' perceptions of flipped classrooms, gender, and country difference
(
IGI Global
, 2020 , Article)
Information technology and the Internet has enabled faculty and educational institutions to implement new teaching methods to enrich the educational environment. The flipped classroom (FC) method changed the teaching ...
