Constitutive analysis for the quantification of hardness decay in a superlattice CrN/NbN hard-coating
( Elsevier B.V. , 2015 , Article)In the present study, a constitutive analysis of the evolution of the mechanical response of a CrN/NbN superlattice coating exposed to high temperature has been performed. Parametric approaches were used to obtain a single ... -
Constitutive models for the prediction of the hot deformation behavior of the 10%Cr steel alloy
( MDPI AG , 2019 , Article)The aim of this paper is to establish a reliable model that provides the best fit to the specific behavior of the flow stresses of the 10%Cr steel alloy at the time of hot deformation. Modified Johnson-Cook and strain-compensated ... -
Constrained metric learning by permutation inducing isometries
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)The choice of metric critically affects the performance of classification and clustering algorithms. Metric learning algorithms attempt to improve performance, by learning a more appropriate metric. Unfortunately, most of ... -
Constraint violations in stochastically generated data: Detection and correction strategies
( Hindawi Publishing Corporation , 2014 , Article)We consider the generation of stochastic data under constraints where the constraints can be expressed in terms of different parameter sets. Obviously, the constraints and the generated data must remain the same over each ... -
Constraint-enhanced role engineering via answer set programming
( Association for Computing Machinery , 2012 , Conference Paper)Role engineering (RE) aims to develop and maintain appropriate role-based access control (RBAC) configurations. However, RE with constraints in place is not well-studied. Constraints usually describe organizations' security ... -
Constraints and Facilitators of Sport Participation in Qatar: Perceptions of Ooredoo Marathon Participants
( Cognizant Communication Corporation , 2021 , Article)The Qatari government has increasingly supported education of Qatar residents on the importance of physical activity, along with developing and improving sport infrastructure, and bidding for and hosting a collection of ... -
Construct Validity in Psychology and Educational Measurement

Construct validity of an instrument for assessment of reflective writing-based portfolios of medical students
( Dove Medical Press , 2020 , Article)Purpose: Assessment of reflective writing for medical students is challenging, and there is lack of an available instrument with good psychometric properties. The authors developed a new instrument for assessment of ... -
The construct validity of session RPE during an intensive camp in young male Karate athletes
( CIC Edizioni Internazionali S.r.l. , 2014 , Article)Background: the aim of this study was to assess the validity of the session rating of perceived exertion (RPE) method and two objective HR-based methods for quantifying karate’s training load (TL) in young Karatekas. ... -
Constructability and Economical Comparison Between Two Proposed Permanent Shoring Systems in Qatar: A Case Study
( Qatar Univesrity Press , 2020 , Conference Paper)This paper introduces the constructability and economic feasibility study of using one of the proposed two types of permanent shoring system for a highway project in Qatar. The cast-in-situ cantilever retaining wall and ... -
Constructing an Intelligent Model Based on Support Vector Regression to Simulate the Solubility of Drugs in Polymeric Media
( MDPI , 2022 , Article)This study constructs a machine learning method to simultaneously analyze the thermodynamic behavior of many polymer-drug systems. The solubility temperature of Acetaminophen, Celecoxib, Chloramphenicol, D-Mannitol, ... -
Constructing and testing the psychometrics of an instrument to measure the attitudes, benefits, and threats associated with the use of Artificial Intelligence tools in higher education
( Kaplan Singapore , 2023 , Article)Under the acceleration in the body of information regarding AI technology and the paucity of instruments that assess the views and reactions of consumers, we have constructed this instrument to measure the attitudes, ... -
Constructing three-dimensional mesoporous bouquet-posy-like TiO2 superstructures with radially oriented mesochannels and single-crystal walls
( American Chemical Society , 2017 , Article)Constructing three-dimensional (3-D) hierarchical mesostructures with unique morphology, pore orientation, single-crystal nature, and functionality remains a great challenge in materials science. Here, we report a confined ... -
Constructing water-resistant CH3NH3PbI3 perovskite films: Via coordination interaction
( Royal Society of Chemistry , 2016 , Article)Organic-inorganic halide CH3NH3PbI3 (MAPbI3) perovskite solar cells (PSCs) have attracted intensive attention due to their high power conversion efficiency and low fabrication cost. However, MAPbI3 is known to be very ... -
CONSTRUCTION CHANGE ORDER MANAGEMENT PROJECT SUPPORT SYSTEM UTILIZING DELPHI METHOD
( Vilnius Gediminas Technical University , 2022 , Article)Change orders are a major challenge in the construction industry due to the associated time and cost impacts. Thus, managing change effectively assists in alleviating cost overruns and delays. Avoiding change orders and ... -
Construction mediation as a developmental process
( Bloomsbury Qatar Foundation Journals , 2013 , Article)This paper seeks to argue that mediation has been hitherto conceived in the construction industry, and indeed by practitioners in other related disciplines such as property management, as largely a “problem-solving” ... -
Construction of (n+ 1) -dimensional dual-mode nonlinear equations: multiple shock wave solutions for (3 + 1) -dimensional dual-mode Gardner-type and KdV-type
( Springer International Publishing , 2019 , Article)The goal of this study is to offer an exclusive functional conversion to produce (n+ 1) -dimensional dual-mode nonlinear equations. This transformation has been implemented and new (3 + 1) -dimensional dual-mode Gradner-type ... -
Construction of a Bacillus thuringiensis genetically-engineered strain harbouring the secreted Cry1Ia delta-endotoxin in its crystal
( Springer Netherlands , 2011 , Article)Unlike other Bacillus thuringiensis Cry proteins, Cry1 Ia does not form a crystal since it is a secreted delta-endotoxin. We have engineered a Cry1 Iac chimeric protein by substituting the C-terminal part of Cry1 Ia by the ...
