An empirical examination of moral hazards and adverse selection on PPP projects: A case study of Ghana
( Emerald Group Publishing Ltd. , 2018 , Article)Purpose: Failures of public?private partnership (PPP) projects are often ascribed to the agency problem, which arise under conditions of inadequate and asymmetric information when a principal (the client) hires an agent ... -
An empirical investigation of critical success factors and performance measures for green manufacturing in cement industry
( Emerald Group Publishing Ltd. , 2016 , Article)Purpose - The purpose of this paper is to aim for the development and analysis of green manufacturing (GM)-based framework on the identified critical success factors (CSFs) and performance measures (PMs) in the context of ... -
An empirical investigation of quality performance expectations in the software industry: A gap analysis approach
( Inderscience , 2014 , Article)The assessment of quality is pervasive but vital in organisations. It is particularly important in the design of an effective quality management system. The assessment is often considered from the perspective of fulfilling ... -
AN EMPIRICAL INVESTIGATION OF THE IMPACT OF DIGITAL TEACHING AND LEARNING ON UNIVERSITY STUDENTS' SATISFACTION LEVELDURING COVID-19 PANDEMIC IN QATAR
(06-2 , Master Thesis)Life is changing rapidly for many reasons, which affects people's mindsets as well as their behaviour. Today, most people rely on technology on a daily basis. Furthermore, the global COVID-19 pandemic has pushed the world ... -
An Empirical Study for PCA- and LDA-Based Feature Reduction for Gas Identification
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)Increasing the number of sensors in a gas identification system generally improves its performance as this will add extra features for analysis. However, this affects the computational complexity, especially if the ... -
An empirical study of intuition and its context
( IEEE Computer Society , 2016 , Conference Paper)Our knowledge of what determines intuitive decision making is still in its early stages, although there is an increasing interest in intuition in the last decade. In order to fill this gap, this study examines the differential ... -
An empirical study on lean awareness and potential for lean implementations in Qatar industries
( Springer-Verlag London Ltd , 2016 , Article)In this study, an investigation on the level of recognition of lean concepts, principles, tools, and techniques in different industrial sectors in Qatar was carried out. The general aim of the study was to determine lean ... -
An energy saving mechanism based on vacation queuing theory in data center networks
( Springer , 2018 , Conference Paper)To satisfy the growing need for computing resources, data centers consume a huge amount of power which raises serious concerns regarding the scale of the energy consumption and wastage. One of the important reasons for ... -
An energy-efficient distributed clustering algorithm for heterogeneous WSNs
( Springer International Publishing , 2015 , Article)Wireless sensor networks (WSNs) were envisaged to become the fabric of our environment and society. However, they are yet unable to surmount many operational challenges such as limited network lifetime, which strangle their ... -
An engineered microfluidic blood-brain barrier model to evaluate the anti-metastatic activity of β-boswellic acid
( John Wiley and Sons Inc , 2021 , Article)Background The development of anti-cancer drugs with the ability to inhibit brain metastasis through the blood-brain barrier (BBB) is substantially limited due to the lack of reliable in vitro models. Main Methods In ... -
An enhanced distance-dependent electric field model for contact-separation triboelectric nanogenerator: Air-breakdown limit as a case study
( Elsevier , 2023 , Article)Theoretical models have been proposed to bring an in-depth understanding of the working mechanisms of triboelectric nanogenerators (TENGs), aiming to enhance their output performance. This work proposes an enhanced ... -
An Enhanced Dynamic-programming Technique For Finding Approximate Overlaps
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)The next generation sequencing technology creates a huge number of sequences (reads), which constitute the input for genome assemblers. After prefiltering the sequences, it is required to detect exact overlaps between the ... -
An enhanced electrocoagulation process for the removal of fe and mn from municipal wastewater using dielectrophoresis (Dep)
( MDPI AG , 2021 , Article)In this study the removal of Fe and Mn from primary treated municipal wastewater using a new electrode configuration in electrocoagulation was evaluated. The used electrode configuration induced a dielectrophoretic (DEP) ... -
An enhanced ensemble deep random vector functional link network for driver fatigue recognition
( Elsevier , 2023 , Article)This work investigated the use of an ensemble deep random vector functional link (edRVFL) network for electroencephalogram (EEG)-based driver fatigue recognition. Against the low feature learning capability of the edRVFL ... -
An enhanced hybrid piezoelectric-electromagnetic energy harvester using dual-mass system for vortex-induced vibrations
( SAGE Publications Inc. , 2021 , Article)This article proposes a novel hybrid piezoelectric-electromagnetic vortex-induced vibration energy harvester from flow of water inside of a pipe. The piezoelectric energy harvester was modeled with a macro-fiber composite ... -
An enhanced nonparametric EWMA sign control chart using sequential mechanism
( Public Library of Science , 2019 , Article)Control charts play a significant role to monitor the performance of a process. Nonparametric control charts are helpful when the probability model of the process output is not known. In such cases, the sampling mechanism ... -
An enhanced performance IPT based battery charger for electric vehicles application
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)World-wide scientists/engineers were motivated to research in the area of renewable energy resources and to reduce the consumption of fossil fuels.
